This study aimed to develop a novel surgery classification for an endoscopic approach to middle ear *** retrospectively analyzed the surgical approaches and outcomes of patients with middle ear *** ear cholesteatoma surgeries were divided into four types and two special types as follows:type I,attic retraction pocket,which only requires tympanostomy tube placement or retraction pocket resection and cartilage reconstruction;typeⅡ,cholesteatoma which is limited to the attic or in which endoscopy can confirm complete removal of mastoid cholesteatoma lesions,including type Ⅱa,requiring only use of a curette,and type Ⅱ b,requiring use of an electric drill or chisel;type Ⅲ,cholesteatoma not limited to the attic,in which endoscopy cannot confirm complete removal of mastoid cholesteatoma lesions,requiring the combined use of endoscope and microscope to perform endoscopic tympanoplasty and"Canal Wall Up"mastoidectomy;type Ⅳ,extensive involvement of mastoid cavity cholesteatoma lesions and/or cases with a potential risk of complications,removal of which can only be performed under a microscope for"Canal Wall Down"*** addition,there were two special types:"difficult external auditory canal"and congenital cholesteatoma in *** our system,type I and type U middle ear cholesteatoma surgery was completely performed under an endoscope ***,estimating the extent of the lesions,determining the choice of mastoid opening and reestablishing ventilation are the key points for an endoscopic approach to middle ear *** classification of endoscopic middle ear cholesteatoma surgery may benefit the selection of surgical indications.

Developing a bridge capping layer between perovskite and hole transport layer materials（HTMs） in the n-i-p perovskite solar cells（pero-SCs） is an effective approach to modify the morphology of HTMs and passivate the perovskite ***, we select the quinoxaline-based bifunctional passivation agent, quinoxalin-6-yl-methylamine hydrochloride（Qx MACl）,as the bridging layer, and a D-A copolymer PBQ12 containing the same quinoxaline unit as an HTM for the n-i-p pero-SCs. Due to the π-π stacking among the common quinoxaline units in the bridge layer and HTM, Qx MACl induces the π-π stacking of the PBQ12 film and improves the film morphology of HTMs with better conductivity. Additionally, Qx MACl can effectively passivate the perovskite surface, and PBQ12 possesses appropriate energy levels and high hole mobility. The pero-SCs based on FAPbI3with PBQ12/Qx MACl treatment showed a higher power conversion efficiency（PCE） of 24.05% and outstanding stability, maintaining 95.4% and 92.1% of its initial PCE after 750 h of storage and after over 800 h of thermal annealing at 85 °C, respectively. To further enhance the PCE of the PBQ12/Qx MACl-based devices, we developed a non-metal ion dopant for the PBQ12 HTM. Through trace doping of PBQ12 HTM by the non-metal ion dopant, the PCE of the PBQ12/Qx MACl-based devices reached 25.24%（the calibrated PCE of 24.55% by the National Institute of Metrology, China）.

The prevalence of pleural effusion caused by hepatocirrhosis ranges from 0.4% to 30%. Some patients with hepatic hydrothorax （HH） fail to respond to aggressive medical management such as albumin application, diuretics, and thoracentesis, and remain refractory massive pleural fluid. The repeated suctions to relieve the symptoms such as respiratory distress are associated with significant hyponatremia and hypoalbuminemia caused by the large volumes of fluid loss. Review of the literature has revealed that, to date, no therapy is ideal. This report describes our experiments in treating HH of patients with cirrhosis and ascites by thoracoscopy and talc poudrage, to offer our efforts to approach the pathogenesis of HH and to explore the new therapeutic strategy.

We report on the first case of a Streptococcus gallolyticus meningocephalitis in China. The bacterium was first isolated from the patient's cerebrospinal fluid and has so far not been associated with human infections of the central nervous system. We hope our case report can give some references for the diagnosis and treatment of the Streptococcus gallolyticus meningocephalitis in China.

AIM: To evaluate the effect of glycine on plasma and liver tissue changes of tumor necrosis factor-α (TNF-α),endothelin-1 (ET-1) and nitric oxide (NO) contents in rats with obstructive ***: Ninety healthy Wistar rats of both sexes weighing 275±25 g were randomly divided into shamoperated, bile duct-ligated, and bile duct-ligated plus glycine-treated groups, the latter was performed with 5 %glycine solution substituting for tap water drunk ad libium for 5 days before and 6 days after operation. Blood and liver tissue were sampled at the time of sacrifice on the 8th day post operation. Plasma total bilirubin, endotoxin, levels,as well as TNF-α, ET-1 and NO contents in liver tissue were ***: Plasma endotoxin and total bilirubin levels were significantly higher in both bile duct-ligated and bile ductligated plus glycine-treated rats than in sham-operated animals (P=0.000613, 0.00921 and 0.00737, 0.00841respectively), whereas they did not display any statistically significant difference between the former groups (P=0.417and 0.374 respectively). likewise, TNF-α, ET-1 and NO contents in both plasma and liver tissue were significantly increased in both bile duct-ligated and bile duct-ligated plus glycine-treated rats compared with sham-operated animals (P=-0.00813, 0.00793, 0.00671, 0.00804, 0.00872, and 0.00947 in plasma and 0.00531, 0.00785, 0.00912, 0.00981and 0.00635 in liver tissue respectively). However, these inflammatory mediators in both plasma and liver tissue were significantly reduced in bile duct-ligated rats fed on 5 %glycine solution compared with that without (P=0.00953,0.00891, 0.0795, 0.00867, 0.0697 and 0.00907 in plasma and liver tissue respectively).CONCLUSION: Reduction of TNF-α, ET-1 and NO contents in plasma and liver tissue of rats fed on glycine may be helpful to alleviate pathological lesions in obstructive jaundice.
