No recurrent fistula was identified with postoperative follow-up 4 - 84 months. Conclusions After recurrent rectovaginal fistula with multiple surgical treatment,the blood supply of local tissue is poor,the scar is serious. Selecting the appropriate timing of operation, adequate preoperative preparation, the application of transverse colostomy and Mason operation in different period could significantly enhance the successful operation rate.

Objective To analyze the application value of the rapid testing for influenza during 2007-2008 flu season at fever clinic in Beijing Chaoyang hospital Methods 500 patients with diagnosis of influenza-like illness were prospectively enrolled. Pharyngeal swabs were collected for influenza viral culture and rapid testing for influenza. Demographic characteristics, age, symptoms, lab tests, symptom recovery time and medical expense were also collected. The sensitivity, specificity, positive predictive value and negative predictive value for rapid testing were analyzed. Results A total of 500 patients were enrolled between Dec 2007 and March 2008. Among them 498 cases were used for analysis. Influenza B was most common by virus culture methed(n=208,41.8%) ,followed by influenza A (n=51,10.2%). The average age was 35, and the ratio of male to female was 1.47:1. Compared with the group of positive culture, patients with influenza were more likely to get cough, sore throat, and nasal congestion (t=13.728, 4.014and 4.720,P<0.001 or 0.05, respectively). A total of 260 cases were subjected to rapid testing, Among them 18 cases were influenza A positive and 132 cases were influenza B positive. The rapid testing had a sensitivity of 77.1 % and a specificity of 70.1%. The positive predictive value was 78.6% and the negative predictive value was 68.2%. The rapid testing had enhanced the proportion of anti-viral treatment from 0 to 26% and reduced the proportion of antibiotic use from 63.4% to 20. 7%. Conclusions Influenza B is the most predominant pathogen during 2007-2008 flu season among patients with influenza-like illness in Beijing. The rapid testing with high sensitivity and specificity provides guidance on clinical practice.

Currently, power generation in China is dominated by thermal power, wind power, nuclear power, and hydropower enterprises. The power source mainly comes from thermal power generation. The occupational hazards in thermal power station are noise, high temperature, power frequency electric fields, dust, and chemical toxins and so on, with noise and dust (silica and coal dust) being the primary factors. The occupational hazards in wind power station are noise, power frequency electric fields, high temperature, low temperature, and chemical toxins (sulfur hexafluoride, toluene, styrene, etc.), with noise and power frequency electric fields being the major concerns. The occupational radiation hazards in nuclear power station are gamma rays, beta rays, X-rays, neutrons, alpha rays, and radioactive aerosols. There is special attention in radiation protection but not enough protection in non-radioactive hazards such as noise, high temperature, and ammonia. The occupational hazards in hydropower station are noise, power frequency electric fields, vibration, radon and its de-composites, and chemical toxins, with noise and power frequency electric fields being the primary hazards. Different categories of power generation enterprises should identify key hazards and work site for occupational disease prevention and control based on the features of occupational hazards. Improving occupational health management and protection levels are essential measures.

predictive value of PLR and NLR for T2DM complicated with CAS plaque.Methods A total of 369 T2DM patients admitted to the Department of Endocrinology,the Third Affiliated Hospital of Xinxiang Medical University from September 2019 to November 2021 were se-lected as research subjects.The clinical data such as gender,age,course of disease,body mass index(BMI),systolic blood pressure(SBP),diastolic blood pressure(DBP),personal history,and history of past illness of patients were collected by searching the electronic medical record system.Neutrophil(NC)count,lymphocyte count(LC)and platelet(PLT)count were detected by fully automated blood routine analyzer,and PLR,NLR were calculated;the levels of fasting blood glucose(FBG),total cholesterol(TC),triglycerides(TG),high-density lipoprotein-cholesterol(HDL-C)and low-density lipoprotein-cholesterol(LDL-C)were detected by biochemical analyzer;the level of glycosylated hemoglobin(HbA1c)were detected by high-performance liquid chromatography.The T2DM patients were divided into T2DM uncomplicated with CAS plaque group(n=94)and T2DM complicated with GAS plaque group(n=275)based on whether they complicated with CAS plaque or not;the general clinical data,blood indicators,and PLR,NLR of patients were compared between the two groups.The T2DM patients were divided into non plaque group(group A,n=94),1 plaque group(group B,n=79),2 plaque group(group C,n=89),and 3 or more plaques group(group D,n=107)based on the number of CAS plaques;the indicators with statistical differences between T2DM uncomplicated with CAS plaque group and T2DM complicated with CAS plaque group of patients were compared among the four groups.According to the PLR quartile,the patients were divided into P1 group(PLR≤94.87,n=93),P2 group(94.87＜PLR≤117.30,n=91),P3 group(117.30＜PLR ≤ 148.53,n=93),and P4 group(PLR＞148.53,n=92),and the detection rate of CAS plaques of patients was compared among the four groups;according to the NLR quartile,the patients were divided into N1 group(NLR≤1.59,n=92),N2 group(1.59＜NLR≤1.93,n=92),N3 group(1.93＜NLR≤2.50,n=93),and N4 group(NLR＞2.50,n=92),and the detection rate of CAS plaque of patients was compared among the four groups.The risk factors of T2DM complicated with CAS plaque was analysed by multivariate logistic regression analysis,and the predictive efficacy of PLR and NLR for T2DM complicated with CAS plaque were evaluated by receiver operating characteristic(ROC)curve.Results The age,course of T2DM,proportion of patients combined with hyper-tension,SBP,PLR,and NLR of patients in the T2DM complicated with CAS plaque group were significantly higher than those in the T2DM uncomplicated with CAS plaque group,while LC and TG levels were significantly lower than those in the T2DM uncomplicated with CAS plaque group(P＜0.05);there was no significant difference in gender,proportion of patients com-bined with hyperlipidemia,proportion of smoking history,proportion of drinking history,and the levels of DBP,BMI,NC,PLT,TC,HDL-C,LDL-C,FBG,HbA1c between the T2DM uncomplicated with CAS plaque group and T2DM complicated with CAS plaque group(P＞0.05).The age,proportion of patients combined with hypertension,course of T2DM,SBP,PLR,and NLR of patients in group B,group C,and group D were significantly higher than that in group A,while LC level was significantly lower than that in group A(P＜0.05).The TG level of patients in group D was significantly lower than those in group A(P＜0.05);there was no statistically significant difference in TG level of patients among group A,group B,and group C(P＞0.05).The age,proportion of patients combined with hypertension,and course of T2DM of patients in group C and group D were significantly higher than those in group B,while the SBP of patients in group D was significantly higher than that in group B(P＜0.05);there was no statistically significant difference in SBP of patients between group C and group B(P＞0.05).The age,proportion of patients combined with hypertension,course of T2DM,and SBP of patients in group D were significantly higher than those in group C(P＜0.05).There was no statistically significant difference in the levels of LC,TG,and PLR of patients among group B,group C,and group D(P＞0.05).The NLR of patients in group D was significantly higher than that in group B(P＜0.05);there was no statistically significant difference in NLR of patients between group C and group B(P＞0.05),and there was no statistically significant difference in NLR of patients between group D and group C(P＞0.05).The detection

group,N3 group,and N4 group showed a significant increase trend(x2=35.170,P=0.000).Multivariate logistic regression analysis showed that age,PLR,and NLR were independent risk factors for T2DM complicated with CAS plaque(odds ratio=1.107,1.017,1.940;P＜0.05).The opti-mal cutoff value of PLR in predicting T2DM complicated with CAS plaque was 119.95,with an area under the curve of 0.680,a sensitivity of 54.7％,and a specificity of 76.3％;the optimal cutoff value of NLR in predicting T2DM complicated with CAS plaque was 1.97,with an area under the curve of 0.698,a sensitivity of 56.5％,and a specificity of 79.6％.Conclusion PLR and NLR are associated with T2DM complicated with CAS plaque,which are independent risk factors for T2DM compli-cated with CAS plaque,and have certain predictive value for T2DM complicated with CAS plaque.

Objective　To investigate the prevalence,age distribution and risk factors of cerebral small vessel disease (CSVD) neuroimaging markers in Shanghai elderly community population.Methods　From August 2016 to October 2019,subjects aged above 50 years and qualified for the study were enrolled from Jingan,Qingpu and Minghang districts in Shanghai.Uniformly designed clinical research forms,neuropsychological assessment,laboratory tests and MRI were performed to gather information and to analyze the prevalence,severity and distribution of lacune,white matter hyperintensity (WMH),cerebral microbleed (CMB) and perivascular space (PVS).Associations between risk factors and neuroimaging markers were analyzed by multivariate logistic regression models.Results　 Among 870 enrolled subjects who had undergone MRI,median age was 68 years and 40.2% male.Lacune,WMH (Fazekas≥2),CMB and PVS were detected in 17.6%,29.4%,27.8%,96.5% of subjects respectively.With every 10 years’increase in age,there was a 35% increase in lacune,126% increase in WMH and 51% increase in CMB.Compared with non-hypertensive subjects,hypertensive subjects had a 1.98-fold of risk detecting lacune on MRI,while a 1.64,1.91,1.45 fold of risk for WMH,CMB and PVS.ConclusionsAge and hypertension are the major risk factors for CSVD in elderly community population.Age-stratified prevalence of single imaging marker and total CSVD score may have a clinical significance in diagnosing CSVD.

In response to the Opinions of the CPC Central Committee and the State Council on Promoting the Inheritance， Innovation， and Development of traditional Chinese medicine（TCM） and the spirit of the National Conference on TCM， Chinese Association of Chinese Medicine organized experts in Otorhinolaryngology Head and Neck Surgery of traditional Chinese and western medicine to discuss the clinical advantages of TCM and integrated traditional Chinese and western medicine in the treatment of allergic rhinitis （AR） and they reached a basic consensus. In recent years， the prevalence of AR has been on the rise， threatening the quality of life of patients and giving rise to a heavy burden to both the patients and the society. AR is resulted from immune imbalance rather than reduced immunity or hyperimmunity， and the imbalance is similar to the Yin-yang disharmony in TCM. In the treatment of this disease， western medicine features rapid onset. However， it is cost-intensive and causes severe surgical trauma， and the recurrence is common. TCM boasts diverse methods for AR， which can be used in all stages of this disease. It has advantages in controlling symptoms such as nasal congestion， runny nose， or dysosmia in the attack stage， preventing recurrence in the remission stage， and treating refractory AR or steroid-resistant AR. In particular， acupuncture enjoys a reputation in treatment of AR， which has been supported by evidence-based medicine and recommended by guidelines. While treating local symptoms of AR， TCM regulates the psychosomatic conditions， which facilitates chronic disease management and long-term follow-up. We should integrate the advantages of TCM and western medicine， give full play to the unique nonnegligible and irreplaceable advantages of TCM， formulate a comprehensive diagnosis and treatment scheme for learning and promotion， and summarize the research outcomes to promote the theoretical innovation of TCM on AR from the perspective of integrated traditional Chinese and western medicine.
