The distillery wastewater of guangdong Jiujiang Distillery, which is characteristic of containing high organic matters and rich total nitrogen, was treated by a combination of methane fermentation and denitrification/nitrification processes. 80% of COD in the raw wastewater was removed by methane fermentation at the COD volumetric loading rate of 20 kg COD/（m^3·d） using the expanded granule sludge bed （EGSB） process. However, almost all the organic nitrogen in the raw wastewater was converted into ammonia by ammonification there. Ammonia and volatile fatty acids （VFA） remaining in the anaerobically treated wastewater were simultaneously removed utilizing VFA as an electron donor by denitrification occurring in the other EGSB reactor and nitrification using PEG-immobilized nitrifying bacteria with recirculation process. An aerobic biological contact oxidization reactor was designed between denitrification/nitrification reactor for further COD removal. With the above treatment system, 18000-28000 mg/L of COD in raw wastewater was reduced to less than 100 mg/L. Also, ammonia in the effluent of the system was not detected and the system had a high removal rate for 900-1200 mg/L of TN in the raw wastewater, only leaving 400 mg/L of nitrate nitrogen.

Chinese Medical Journal 2006年第11期119卷 930-938页

作者： ZHANG Jun-hua huang yu-guang Department of Anesthesiology Peking Union Medical College Hospital Chinese Academy of Medical Sciences Beijing 100730China

Objective To review the relationship between the immune system and the mechanism of pain. Data sources Related researches published in the period of 1987-2005 were systematically reviewed. Study selection Articles about the immune system and pain were selected. Data extraction Data were mainly extracted from 74 articles which are listed in the reference section of this review. Results Pain was classically viewed as being mediated solely by neurons. However, growing evidence has showed the possible relationships between the immune system and the central nervous system. In this article, we reviewed the role of the immune system in the development of pain, together with the importance of the glia in this process. These findings suggest a novel approach to pain control in the future. Conclusions The immune system plays a potential but important role in the development of pain.

Calpain Inhibitor Reduces Cancer-induced Bone Pain Possibly Through Inhibition of Osteoclastogenesis in Rat Cancer-induced Bone Pain Model

引用

Chinese Medical Journal 2015年第8期128卷 1102-1107页

作者： Jia-Ying Xu yu Jiang Wei Liu yu-guang huang Department of Anesthesiology Peking Union Medical College Hospital Chinese Academy of Medical Sciences Beijing 100730 China Department of Anesthesiology Sun Yat-sen University Cancer Center State Key Laboratory of Oncology in South China Guangzhou Guangdong 510060 China

Background： Calpain, a calcium-dependent cysteine protease, has been demonstrated to regulate osteoclastogenesis, which is considered one of the major reasons for cancer-induced bone pain （CIBP）. In the present study, calpain inhibitor was applied in a rat CIBP model to determine whether it could reduce CIBP through regulation of osteoclastogenesis activity. Methods： A rat CIBP model was established with intratibial injection of Walker 256 cells. Then, the efficacy of intraperitoneal administered calpain inhibitor III （MDL28170, 1 mg/kg） on mechanical withdrawal threshold （MWT） of bilateral hind paws was examined on postoperative days （PODs） 2, 5, 8, 11, and 14. On POD 14, the calpain inhibitor＇s effect on tumor bone tartrate-resistant acid phosphatase （TRAP） stain and radiology was also carefully investigated. Results： Pain behavioral tests in rats showed that the calpain inhibitor effectively attenuated MWTs of both the surgical side and contralateral side hind paws on POD 5, 8, and 11 （P 〈 0.05）. TRAP-positive cell count of the surgical side bone was significantly decreased in the calpain inhibitor group compared with the vehicle group （P 〈 0.05）. However, bone resorption and destruction measured by radiographs showed no difference between the two groups. Conclusions： Calpain inhibitor can effectively reduce CIBP of both the surgical side and nonsurgical side after tumor injection in a rat CIBP model. It may be due to the inhibition of receptor activator of nuclear factor-kappa B ligand-induced osteoclastogenesis. Whether a calpain inhibitor could be a novel therapeutic target to treat CIBP needs further investigation.

引用

Chinese Medical Journal 2011年第22期124卷 3721-3725页

作者： DU Jin huang yu-guang yu Xue-rong ZHAO Na Department of Anaesthesiology Subei People＇s Hospital Yangzhou University Yangzhou Jiangsu 225001 China

Background Ketamine is hypothesized to reduce perioperative endocrine-metabolic and inflammatory responses in cardiac surgery patients. This randomized, placebo-controlled, double-blind study was performed to determine whether perioperative endocrine-metabolic and inflammatory responses are attenuated by preoperative administration of ketamine to healthy females receiving elective laparoscopic surgery. Methods Forty female patients with American Society of Anesthesiologist classification Ⅰ or Ⅱwho elected to receive gynecological laparoscopic surgery were randomly assigned to the ketamine-treated （group K; n = 20） or control （group C n = 20） group. At 2 minutes prior to induction patients in group K received ketamine （0.25 mg/kg） whereas those in group C received normal saline. All patients received standardized general anesthesia. Serum glucose and cortisol values were measured before ketamine administration （TO）, 2 minutes after tracheal intubation （T1）, 30 minutes after skin incision （T2）, 2 minutes after tracheal extubation （T3） and 1 hour postoperatively （T4）. Serum interleukin-6 and tumor necrosis factor-α values were determined at TO and T4. Postoperative analgesic efficacy, side effects of administered drugs, and time to discharge were recorded. Results Compared with subjects in group C, those in group K had lower serum glucose values at T1, T2, T3 and T4 and lower serum cortisol values at T4 （P 〈0.05）. Postoperative interleukin-6 and tumor necrosis factor-α concentrations for group K were lower than those for group C （P 〈0.05）. Postoperative visual analog scale scores at rest, cumulative fentanyl consumption, and time to discharge were lower in group K as compared to group C （P 〈0.05）. No significant differences in drug side effects were observed postoperatively between the two groups. Conclusion Endocrine-metabolic and inflammatory responses to laparoscopic surgery are attenuated in part by Dre-incisienal administration of ketamine.

Chinese Medical Journal 2010年第24期123卷 3725-3727页

作者： ZHU Bin MA Lu-lu YE Tie-hu huang yu-guang Department of Anesthesiology Peking Union Medical College Hospital Chinese Academy of Medical Sciences & Peking Union Medical College Beijing 100730 China

Primary tracheal tumors comprise a rare group of benign and malignant tumors of the trachea. Since they cause progressive airway obstruction, no matter benign or malignant, they are life-threatening if not properly treated. Tracheal surgery is the most effective treatmentand has produced a decent resectability rates for tracheal tumors varying from 63% to 90%. The procedure for tracheal tumors usually includes two key steps, tracheal resection and airway reconstruction, which generate not just challenges for thoracic surgeons but particularly for anesthesiologists. We report a successful case of peri-anesthesia management for the tracheal surgery.

引用

Chinese Medical Journal 2013年第18期126卷 3464-3469页

作者： LIU Zi-jia yu Chun-hua XU Li HAN Wei JIANG Jing-mei huang yu-guang Department of Anesthesiology Peking Union Medical College Hospital Peking Union Medical College Chinese Academy of Medicine Science Beijing 100730 China Department of Epidemiology and Statistics Peking Union Medical College School of Basic Medicine Chinese Academy of Medical Sciences Institute of Basic Medical Sciences Beijing 100005 China

Background Few studies have investigated perioperative major adverse cardiac events （MACEs） in elderly Chinese patients with coronary heart disease （CHD） undergoing noncardiac surgery. This study examined the incidence and risk factors for perioperative MACE in elderly patients who underwent noncardiac surgery, and established a risk stratification system. Methods This retrospective observational clinical study included 482 patients aged -〉60 years with CHD who underwent elective major noncardiac surgery at the Peking Union Medical College Hospital. The primary outcome was MACE within 30 days after surgery. Risk factors were evaluated using multivariate Logistic regression analysis. Results Perioperative MACE occurred in 61（12.66%） of the study patients. Five independent risk factors for perioperative MACE were identified： history of heart failure, preoperative arrhythmia, preoperative diastolic blood pressure 〈75 mmHg, American Society of Anesthesiologists grade 3 or higher, and intraoperative blood transfusion. The area under the receiver operating characteristic curve for the risk-index score was 0.710＋0.037. Analysis of the risk stratification system showed that the incidence of perioperative MACE increased significantly with increasing levels of risk. Conclusions Elderly Chinese patients with CHD who undergo noncardiac surgery have a high risk of perioperative MACE. Five independent risk factors for perioperative MACE were identified. Our risk stratification system may be useful for assessing perioperative cardiac risk in elderly patients undergoing noncardiac surgery.
