Objective To investigate the formaldehyde pollution in a tunnel. Methods The concentration of formaldehyde was determined in rooms for different function,in rooms with different number of furniture,in different position in a tunnel and at different time of using air cleaner in Oct. 2006. Results The total rate of exceed standard of formaldehyde level in the tunnel was 82.9%,the rate of exceed standard in the rooms disposed by all the furniture was 100%,the rate of exceed standard in the front of the tunnel was lowest (63.6%). Using the air cleaner,the rate of exceed standard decreased in degree. Conclusion The main source of formaldehyde pollution in a tunnel is furniture,formaldehyde is the main air pollutant in a tunnel.

Objective]The paper summarizes academic thought of Professor ZHAO Zhiqiang syndrome differentiation and treatment of adenomatous polyp of colon. [Method]By learning from ZHAO Zhiqiang and studying the medical record of adenomatous polyp of colon,sum up professor ZHAO Zhiqiang′ s experiences from etiology and pathogenesis, differential treatment, administered medical herbs and prescription ,and with one case for detailed explanation. [Results] Professor ZHAO thinks that the pathogeny raletes to exopathy, diet, emotion, weakness of the spleen and stomach, physique, smoke poison,influence of other diseases,the key of pathogenesis is phlegm, blood stasis and toxin stagnation, accumulation of intestine, Qi is out of adjustment, the conduction loss of us, He believes that the syndrome diagnosis of the disease is different from others, the syndrome diagnosis should include disease syndrome elements, syndrome elements of disease location and morbid state, disease syndrome elements should need the help of the modern medical endoscope and pathology, and ill treatment to detoxify the anti-cancer variable as the core, supplemented with Ruanjian Sanjie,coordinating zang and fu, modification according to symptoms.[Conclusion] Professor ZHAO's treatment of adenomatous polyp of colon has rich experience and prominent features, it is worth clinical promotion.

Objective To explore the safety and effectiveness of enhanced recovery after surgery (ERAS) after laparoscopic radical gastrectomy for gastric cancer.Methods From January 2014 to December 2015,167 gastric cancer patients undergoing laparoscopic radical gastrectomy with D2 lymphadenectomy were divided into the enhanced recovery after surgery group (ERASG,67 cases) and 102 cases the conventional surgery group (CSG,102 cases).The general status,tumor stage,postoperative recovery,complications,hospitalization time and 30 day readmission were compared between ERASG and CSG.Results The first exhaust time in ERASG and CSG were (2.6 ± 1.1) days and (3.8 ± 1.3) days (t =-6.494,P ＜ 0.01).Statistical analysis showed that there was no significant difference in the postoperative hospitalization time,30 day readmission rate,complications,anastomotic leakage,wound infection,pneumonia,gastric retention and intestinal obstruction between of ERASG and CSG (all P ＞ 0.05).Conclusions Patients in ERASG have quicker postoperative recovery than those in CSG,with similar postoperative complications.

目的探讨认知康复在脑损伤恢复期的重要性和必要性。方法 60例患者随机分为非介入认知康复组(A组)和介入认知康复组(B组),每组30例。A组为只接受部分康复项目(OT、PT、ST或高压氧),B组在A组的基础上加用认知训练。通常康复训练进行3—4次/天,45分钟/次。高压氧治疗每日1次,10—12天为1个疗程,治疗3—5个疗程,平均36个疗程。结果A组与B组比较在LOTCA评价、FIM评价和Fugl-Meyer评价上都有显著性差异,其中LOTCA评价有非常显著性差异。 结论认知康复在脑损伤恢复后期是必要的。

Objective To explore the incidence rate and the risk factors of deep vein thrombosis (DVT) in patients with traumatic fractures so as to provide references for prevention of DVT.Methods All of 534 Patients with fresh four extremities or pelvic fracture between January 2010 and December 2013 were involved in this study.The incidence of DVT under 5 risk factors including general state, injury type, fracture condition, operation and laboratory examination were analyzed.Each patient underwent three Doppler ultrasound exams in actions as the epidemiology diagnostic criterion for DVT.Results The total incidence rate of DVT in 534 patients was 11.99％.The univariate analysis showed that male patients with age≥60 years, BMI≥25 kg/m2, history of smoking, lack of exercises, history of diabetes, hypertension and coronary artery disease had higher incidence rate of DVT.In different injury types, the fall injury caused the highest incidence rate of DVT (45.71％).There were different DVT rates for different fracture sites, with the highest incidence rate of DVT for femur shaft fracture (20.69％).The incidence rate of DVT was 50.00％ for fractures of more than three parts, 15.29％ for fractures of two parts and only 3.98％ for sole part.The incidence rate of DVT for comminuted fractures was higher than others.The operation duration, massive transfusion during operation and general anesthesia were related with the increase of incidence of DVT.Positive ACA and enhancement of D-dimer, Fib and CRP were related with the increase of incidence of DVT.Conclusion The incidence of DVT in patients with traumatic fractures approaches a considerable level.It has relationships with age≥60 years, BMI≥25 kg/m2, history of smoking, fall injury, fracture of femoral shaft and hip, more than three parts of fractures, comminuted fractures, operation duration≥2 hours, largely blood transfused, massive transfusion during operation, general anesthesia, positive ACA, enhancement of D-dimer, Fib and CRP.The surgeons should recognize the importance to prevent DVT and PE in the traumatic patients.

Objective To explore the clinical effect of IFN combined with adefovir dipivoxil in the treatment of patients with the hepatitis B and hepatitis C overlapping infection.Methods 90 cases of hepatitis B overlapping infection of hepatitis C were divided into control group(n =43) and treatment group(n =47).The control group was treated with IFN,the treatment group was treated with IFN and adefovir dipivoxil.Results The treatment group was better than the control group in the liver function,HBV DNA,HCV RNA.At the 24th weeks,the negative rates of HBV DNA and HCV RNA in the control group were 14 (32.6%) and 18 (41.9%),while there were were 38 (80.9%) and 34(72.3%) in the treatment group.There was significant differences between the two groups(x2 =6.43,5.28,all P ＜ 0.05).Conclusion The clinical efficacy of IFN combined with adefovir dipivoxil for the hepatitis B and hepatitis C overlapping infection patients was significant better than IFN,which is worthy of clinical application.

Objective To explore the impact of puerarin treatment on autophagy in rats with traumatic brain injury (TBⅠ) and the underlying mechanism.Methods Seventy five Sprague-Dawley (SD) rats were randomized into 5 groups:sham group (S group,n =15),traumatic brain injury group (TBⅠ group,n =15),TBⅠ + puerarin treatment group (TBⅠ + Pue group,n =15),TBⅠ + JNK inhibitor group (TBⅠ + SP group,n =15),and TBⅠ + JNK activator + Pue (TBⅠ + An + Pue group,n =15).Feeney method was applied to make rats with TBⅠ model.Mter that,head water content and neurological deficit score (NDS) were measured and recorded at day 1,3 and 7 in each group.Western blot was used to measure the JNK activity and autophagic marker proteins,including LC3B and Beclin1.Results Compared to S group,the head water content and NDS were decreased significantly among the others (P ＜ 0.05).The head water content and NDS in TBⅠ + Pue and TBⅠ + SP groups was decreased remarkably compared with TBⅠ group.Combined with puerarin and animycin treatments failed to reduce head water content and NDS compared to the TBⅠ + Pue group.Activated autophagy could be observed in TBⅠ group compared to S group.Compared to group S,LC3Ⅱ,Beclin1 and P-JNK1 were increased significantly.Pue and SP could reduce their expressions,respectively.Combined with puerarin and animycin treatments failed to reduce LC3Ⅱ,Beclin1 and P-JNK1 compared to TBⅠ + Pue group.Conclusions Puerarin could protect rats with TBⅠ via inhibiting autophagy,JNK signal pathway could involve the process of puerarin regulating autophagy.
