Chinese Journal of Practical Internal Medicine 2000;0(12):-
Gastric mucosa can be damaged by acute and chronic ethanol intake.Alcohol can cause acute and chronic gastric inflammation,such as mucosa hyperemia,edema,hemorrhage,erosion and ulcer formation.In this article we review the metabolism of ethanol,mechanism.The type of alcohol-induced gastric mucosal and therapy on gastric mucosal lesions induced by alcohol.
2.A Review of Environmental Estrogenic Effects of Alkylphenols
Journal of Environment and Health 1992;0(04):-
Alkylphenols(APs) , the second most widely used commercial non-ionic surfactants in the world, are the main degradated productions of alkylphenol ethoxylates (APEs). The structure, biodegradation, transportation and distribution in environment, environmental monitoring and management are reviewed in this paper. Many meaurement methods of APs show that APs possess estrogenoid effects, that mainly disturb endocrinal and reproductive system, especially, estrogen-dependent organs. APs are associated with decreased fertility, reproductive disfunction, inferbility and cancer formation. APs are able to bind estrogen receptors, to imitate or antagonize estrogen effects, to disturb formation and metabolism of endogenous hormones and receptors. APs are also able to change the structure, quantity and function of cells and to disturb the kinetics of cellcycle at cytological and molecular levels. The more work on epidemiological study and mechanism of APs are needed. Management program for controlling environmental pollution caused by APs is being speedily investigated and put into practice progressively. It is necessary to restrict the use of APEs.
3.Intramedullary pin versus plate for treatment of displaced mid-shaft clavicle fractures: a meta-analysis
Chinese Journal of Orthopaedic Trauma 2014;16(7):591-598
Objective To compare the clinical efficacy of intramedullary pin versus plate fixation for displaced mid-shaft clavicle fractures.Methods The databases,PubMed,CENTAL and CBM,were searched according to the standards of the Cochrane Collaboration for all the randomized controlled trials (RCTs) and clinical controlled trials (CCTs) comparing intramedullary pin with plate fixation for treatment of displaced mid-shaft clavicle fractures.In addition,hand search was also conducted in relevant journals.Time limit for search was from the beginning till December 2013.Trial quality was assessed using the modified Jadad scale and effective data were pooled for Meta analysis with software RevMan5.2.7,including wound infection,hospital stay,wound size,intraoperative blood loss,operation duration,implant irritation,implant problems,delayed union,malunion,nonunion,total complications and Constant scoring.Results Three RCTs and 7 CCTs with 697 patients were included in our study.The modified Jadad scoring showed fine quality of the 10 trials.Intramedullary fixation was significantly superior to plate fixation in wound size,intraoperative blood loss,operation duration,hospital stay,wound infection,and symptomatic hardware (P < 0.05),but led to a significantly higher rate of implant problems (P < 0.05).However,no significant differences were identified in total complication rate,delayed union,nonunion,malunion or Constant score (P > 0.05).Conclusions The superiority of intramedullary fixation for displaced mid-shaft clavicle fracture lies in its advantages of minimally invasion,such as limited incision,less intraoperative bleeding,shorter operation time and hospital stay,less wound infection and implant irritation.Ahhough intramedullary fixation may lead to a higher rate of implant problems,it shows no significant differences from plate fixation in bone healing and functional recovery.

In recent years,along with social economic development and population aging,more and more fracture patients have received internal fixation and artificial joint replacement.Postoperative infection related to orthopedic implants is a catastrophic complication which imposes serious psychological,physiological and economic burdens on the patients.Therefore,it is necessary to be able to make an early diagnosis of the infection.However,diagnosis of implant-related infection is always a clinical problem for orthopedists.Currently,it is thought to be a valuable way to judge orthopedic implant infection by monitoring inflammatory cytokines.This article will offer an overview on the progress in research of diagnosis values of different inflammatory cytokines in postoperative infection related to orthopedic implants.

Third-generation aromatase inhibitors (AIs) have been considered as standard adjuvant endocrine therapy for hor-mone-responsive breast cancer in postmenopausal women. Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) are prevalent among patients undergoing AI therapy;these symptoms result in reduced quality of life and poor dependence to AI treatment. The mechanisms mediating AIMSS and the effective management of AIMSS have not been extensively investigated. This article re-views the incidence, clinical characteristics, possible mechanisms, and treatment of AIMSS.

Objective To establish a method to detect viral integrity of human papillomavirus in women cervical HPV infection. Methods We amplified E6/E7 gene and E2 gene of HPV16,then inserted them into a plasmid containing single copy HBB gene. HPV16 infected cervical epithelium samples were screened out by genotyping with RDB of flow-through hybridization assay.Fluo-rescence quantitive PCR data of HBB,viral E2 gene and viral E6 gene of all samples were standardized by compared with respective parameters of the plasmid.The ratio IHPV and CHPV were calculated to find out E2 gene disruption and viral copies per cell in the cer-vical samples,respectively.Results The plasmid constructed for standardization was proved effective to make the FQ-PCR data of E2 gene,E6 gene and HBB gene comparable.Thirty-seven HPV16 positive cervical epithelium samples included 22 cases from women whose TCT were normal,and 15 cases from women who confirmed HIL/CIN 2-3 or above through colposcopic examina-tion plus biopsy.Fifteen samples were detected E2 gene disruption,including 10 HIL/CIN 2-3 or above samples and 5 TCT normal samples.E2 gene integrity in different groups were statistically significant different(P <0.05).The average viral copies per cell dis-played a significant decline along with E2 gene disruption(P <0.05).Conclusion The tandem single copy gene plasmid standard-ized methord for the detection of E2 gene disruption caused by viral integration in HPV16 infected cervical cells is feasible and effec-tive.

Objective To evaluate the renal involvement and therapeutic effect on ANCA-associated vasculitis(ASV) . Methods Fifty-six cases were diagnosed as ASV from Oct 1997 to Mar 2001. Among them, 21 cases received renal biopsies. According to disease activity and severity, Use following treatment protocols were choosed: (1) double pulse therapy; (2) single pulse therapy; (3) oral prednisone and/or low dose of CTX; (4) blood purification technique and/or immunosuppressive therapy. Remission rate was also analyzed. Results 96. 4% of case suffered with renal involvement. 91. 1% with acute renal failure, 96.4% with severe renal failure, 98. 2% with multiple organs involvement. The mortality was 19. 6% and the remission rate 67. 9%. 12. 5% of cases lost follow-up. ConclusionsRenal involvement is common and serious in ASV patients. Individualized and early therapy, as well as valuable urgent renal biopsy are necessary. To those who have entered ESRD, immunosuppressive agents could be used to decrease the extra-renal complication.
