Progress in risk factors for gallstone formation and prevention strategies for stony stage / 国际外科学杂志

Gallstone is a common and frequent disease and frequent incidence, secondary infection and cancer seriously affect the health of patients. Academic organizations in different regions have issued multiple guidelines and consensus to promote the normative diagnosis and treatment of gallstones. However, in clinical practice, most symptomatic gallstones are treated, while the formation and prevention process of gallstones are ignored, making the concept of treating without a disease has not been strengthened.This article reviews the risk factors and mechanisms of gallstone formation, and points out the importance of effective prevention during stone formation. In the stage of gallstone formation, the high risk factors of stone formation can be analyzed through two aspects of injury factors and protective factors, and the high risk groups of stone formation can be screened out. According to the pathophysiological progression of gallstones, personalized prevention and follow-up strategies can be developed for the stone formation stage of gallstones.

Disputes and thinking on the clinical diagnosis and treatment of asymptomatic gallstones / 国际外科学杂志

Cholecystolithiasis is a common clinical disease, which can be secondary to cholecystitis, cholangitis, pancreatitis and gallbladder cancer. Many patients with gallstone have no obvious clinical symptoms such as biliary colic. Some patients are indeed asymptomatic because there are not obstruction and inflammation. However, some patients have no symptoms due to ignorance, mistaken for stomach pain, enteritis, etc. Some patients have no symptoms because of insensitivity and insufficient perception. For other patients with abnormal gallbladder morphology and structure, non-functional gallbladder must be no pain. To clarify the concept, diagnosis and classification of asymptomatic gallstones according to pathophysiological stages is conducive to the development of personalized management strategies. According to guidelines formulated by different periods, different regions and different medical institutions, there are many controversies regarding the management of asymptomatic gallstones, including regular follow-up, drug treatment, surgical resection or gallblades-saving lithotomy. Reasonable personalized diagnosis and treatment requires more in-depth basic research evidence.

Research progress in surgical diagnosis and treatment of gallstones and acute calculous cholecystitis in the elderly / 国际外科学杂志

Gallstones and acute calculous cholecystitis are common diseases in surgery. China has entered an aging society. Elderly patients are a high incidence group of gallstones and acute calculous cholecystitis. Their surgical diagnosis and treatment strategies need to be formulated individually, and reasonable diagnosis and treatment methods should be comprehensively selected according to the patient′s condition and the medical level of the medical institution. For those who are in good physical condition and can tolerate the operation, it is recommended to give priority to surgical treatment, and the minimally invasive surgery mainly suitable for laparoscopic cholecystectomy (LC) is preferred. Open surgery is more appropriate for complicated conditions or patients whose general conditions are not suitable for laparoscopic surgery. Other minimally invasive treatment measures can be applied at the same time. For patients who can not tolerate surgical treatment, puncture, endoscopy, intervention and other means can be selected, combined with drugs for conservative treatment, so as to obtain the opportunity of surgical treatment or improve the prognosis. In this paper, the latest research literature at home and abroad has been collected to review and summarize the latest research progress in the physiology and aging characteristics of the biliary tract in the elderly, the diagnosis and treatment of gallstones and acute calculous cholecystitis. It is hoped that this paper can provide reference for the clinical diagnosis and treatment of such diseases, and think and prospect the future research.

Clinical effect of diode laser on treatment of moderate to severe acne / 中华医学美学美容杂志

Objective To evaluate the efficacy and safety of 650 nm,810 nm diode laser on the treatment of moderate to severe acne.Methods A total of 87 patients with moderate to severe acne were divided into diode laser group (group A) and medication group (group B).In group A,the patients were irradiated with 650,810 nm diode laser at the fluence of 400-450 mW distance of 2-3 cm.In group B,the patients were treated with roxithromycin combined with vitamin B6 and gel lincomycini.Clinical follow-up was performed every week for 4 months.All the adverse effects were recorded.Results There was no significantly statistical difference in the cure rate between the two groups (group A versus group B at 2 weeks:65.0 ％ versus 42.6 ％,P＞0.05; at 4 weeks:92.5 ％ versus 76.5 ％,P＞0.05).However,the recurrence rate of group A was much lower than that of group B (30.0 ％ versus 61.7 ％,P＜0.01).There were no severe adverse effects in both groups during the period of the follow-up.Conclusions Compared to the medication,650,810 nm diode laser appears to be associated with lower recurrence rate in the treatment of moderate to severe acne.
