Wavelength-interval switchable Brillouin–raman random fiber laser through Brillouin pump manipulation

Chinese Physics B 2024年第7期33卷 374-379页

A wavelength-interval switchable Brillouin–raman random fiber laser(BrrFL) based on Brillouin pump(BP) manipulation is proposed in this paper. The proposed wavelength-interval switchable BrrFL has a full-open cavity configuration, featuring multiwavelength output with wavelength interval of double Brillouin frequency shifts. Through simultaneously injecting the BP light and its first-order stimulated Brillouin-scattered light into the cavity, the laser output exhibits a wavelength interval of single Brillouin frequency shift. The wavelength-interval switching effect can be manipulated by controlling the power of the first-order stimulated Brillouin scattering light. The experimental results show the multiwavelength output can be switched between double Brillouin frequency shift multiwavelength emission with a broad bandwidth of approximately 60 nm and single Brillouin frequency shift multiwavelength emission of 44 nm. The flexible optically controlled random fiber laser with switchable wavelength interval makes it useful for a wide range of applications and holds significant potential in the field of wavelength-division multiplexing optical communication.

Adenocarcinoma and infection in a solitary hepatic cyst: A case report

World Journal of Gastroenterology 2005年第12期11卷 1881-1883页

Solitary non-parasitic liver cysts are being increasingly diagnosed due to the increased use of abdominal sonography. The majority of solitary liver cysts are asymptomatic; however, there are some complications which include infection, perforation, spontaneous hemorrhage, obstructive jaundice and neoplastic degeneration. In some cases a cystic liver lesion may mimic a tumor and is difficult to differentiate with standard imaging studies or fine needle aspiration cytology. Here in, we report a case of adenocarcinoma arising in a solitary hepatic cyst complicated with Klebsiella pneumoniae infection. High levels of CEA in the cyst fluid levels suggested malignancy, which was confirmed by pathology of the resected specimen.

AIM： To define the optimal injection volume of epinephrine with high efficacy for hemostasis and low complication rate in patients with actively bleeding ulcers. METHODS： This prospective, randomized, comparative trial was conducted in a medical center. A total of 228 patients with actively bleeding ulcers （spurting or oozing） were randomly assigned to three groups with 20, 30 and 40 mL endoscopic injections of an 1：10000 solution of epinephrine. The hemostatic effects and clinical outcomes were compared between the three groups. rESULTS： There were no significant differences in all background variables between the three groups. Initial hemostasis was achieved in 97.4%, 98.7% and 100% of patients respectively in the 20, 30 and 40 mL epinephrine groups. There were no significant differences in the rate of initial hemostasis between the three groups. The rate of peptic ulcer perforation was significantly higher in the 40 mL epinephrine group than in the 20 and 30 mL epinephrine groups （P 〈 0.05）. The rate of recurrent bleeding was significantly higher in the 20 mL epinephrine group （20.3%） than in the 30 （5.3%） and 40 mL （2.8 %） epinephrine groups （P 〈 0.01）. There were no significant differences in the rates of surgical intervention, the amount of transfusion requirements, the days of hospitalization, the deaths from bleeding and 30 d mortality between the three groups. The number of patients who developed epigastric pain due to endoscopic injection, was significantly higher in the 40 mL epinephrine group （51/76） than in the 20 （2/76） and 30 mL （5/76） epinephrine groups （P 〈 0.001）. Significant elevation of systolic blood pressure after endoscopic injection was observed in the 40 mL epinephrine group （P 〈 0.01）. Significant decreasing and normalization of pulse rates after endoscopic injections were observed in the 20 mL and 30 mL epinephrine groups （P 〈 0.01）.CONCLUSION： Injection of 30 mL diluted epinephrine （1：10000） can effectively prevent recurrent bleedin

AIM: To analyze systematically our experience over 22 years with symptomatic acquired diverticular disease of the jejunum and ileum, exploring the clinical manifestations and diagnosis of this rare but life-threatening ***: The medical records of patients with surgically confirmed symptomatic jejunoileal diverticular disease were retrospectively reviewed. Data collected included demographic data, laboratory results, clinical course (acute or chronic), preoperative diagnosis, and operative findings. Inclusion criteria were as follows: (1) surgical confirmation of jejunoileal diverticular disease and (2)exclusion of congenital diverticula (e.g. Meckel's diverticulum).rESULTS: From January 1982 to July 2004, 28 patients with a total of 29 operations met the study criteria. The male:female ratio was 14:14, and the mean age was 62.6±3.5 years. The most common manifestation was abdominal pain. In nearly half of the patients, the symptoms were chronic. Two patients died after surgery. Only four cases were correctly diagnosed prior to surgery, three by small bowel ***: Symptomatic acquired small bowel diverticular disease is difficult to diagnose. It should be considered in older patients with unexplained chronic abdominal symptoms. A small bowel series may be helpful in diagnosing this potentially life-threatening disease.

report of gossypiboma from the standpoint in medicine and law

World Journal of Gastroenterology 2005年第8期11卷 1248-1249页

作者： Li-rung Shyung Wen-Hsiung Chang shee-Chan Lin Shou-Chuan Shih Chin-roa Kao Sun-Yen Chou Division of Gastroenterology L.L.B. Department of LawNational Taiwan UniversityChina

We report on a case of gossypiboma. A 78-year-old man was admitted to our hospital with acute abdomen. He had undergone an operation for colon cancer 4 mo *** ultrasonography revealed an echogenic lesion with a hypoechoic rim and strong posterior acoustic shadowing in the lower abdomen. Diagnosis of gossypiboma can be made by ultrasonography to avoid loss-of-chance of survival. We reviewed the English literature briefly of gossypiboma from the medical and juridical view. According to the theory of loss-of-chance, the damage of plaintiff is the loss of the chance of survival or recovery, rather than the final harm. The victim would allow recovery for the loss of the chance from the defendant. But the plaintiff would show by a preponderance that he was deprived of a betterchance of a cure. Under the proposed rule, the compensable value of the victim would be the plaintiff's compensation for the loss of the victim's chance of survival.

AIM： To analyze the characteristics of multiple primary malignancies （MPMs） of digestive system; including incidence, types of tumor combinations, time intervals between development of multiple tumors, clinical course,and prognostic factors affecting survival and ***： Data from a total of 129 patients treated from January 1991 to December 2000 for pathologically proved MPMs, including at least one originating from the digestive system, were reviewed ***： Among 129 patients, 120 （93.02%） had two primary cancers and 9 （6.98%） had three primary cancers. The major sites of MPMs of the digestive system were large intestine, stomach, and liver. Associated nondigestive cancers included 40 cases of gynecological cancers, of which 31 were carcinoma of cervix and 10 cases of genitourinary cancers, of which 5 were bladder cancers. Other cancers originated from the lung, breast,nasopharynx, larynx, thyroid, brain, muscle, and *** tract cancers, especially cervical, ovarian,bladder, and prostate cancers were the most commonlyassociated non-G! cancers, followed by cancer of the lung and breasts. Forty-three cases were synchronous, while the rest （86 cases） were metachronous cancers. Staging of MPMs and treatment regimes correlated with the prognosis between survival and non-survival ***： As advances in cancer therapy bring about a progressively larger percentage of long-term survivors, the proportion of patients with subsequent primary lesions will increase. Early diagnosis of these lesions, based on an awareness of the possibility of second and third cancers, and multidiscipiinary treatment strategies will substantially increase the survival of these patients.
