Objective To evaluate the feasibility, advantages and pitfalls of trans-gastric, trans-colonic and trans-umbilical peritoneoscopy, and to compare pure natural orifice transluminal endoscopic surgery (NOTES) with hybrid NOTES. Methods Two female pigs of 30kg were used in the study, one for pure NOTES, the other for hybrid NOTES. Each pig received trans-gastric, trans-colonic and trans-umbilical peritoneoscopy, respectively, followed by postmortem examination for organic lesions and closure of incisions.The two approaches were compared in terms of intra-operative situation and manipulation. Results The vital signs of the pigs were stable during the procedures, with no peri-incision organic lesions. There were blind areas in trans-gastric as well as in trans-colonic peritoneoscopy. It was easier to close the colonic incision than the gastric one. The situation in trans-umbilical peritoneoscopy was similar to laparoscopic surgery. Hybrid NOTES seemed superior to pure NOTES with regard to safe access, stable pneumo-peritoneum and adequate visualization. Conclusion Three routes for NOTES appear to be reasonable and feasible. Hybrid NOTES is more effective and safer than pure NOTES with current instruments.

Objective To study whether the correlation exists between 6 kinds of autoimmune antibodies and female infertility . Methods The protein microarray technique was adopted to detect serum antibodies of anti-sperm antibodies(ASAb) ,anti-endome-trial(AEmAb) ,anti-zona pellucida(AZpAb) ,anti-ovarian(AVoAb) ,anti-hCG(AhCG Ab) and anti-trophoblastic(ATAb) in 140 ca-ses of female infertility and the correlation between these 6 kinds of antibody with female infertility was evaluated .Results Com-pared with the control group ,except AvoAb ,the positive rates of other 5 kinds of antibody had statistically significant differences (P<0 .05) .In the infertility group ,the positive rate of the combined detection of these 6 kinds of autoimmune antibody had statisti-cal difference compared with that of single item detection (P<0 .05) .The positive rate of these 6 kinds of autoimmune antibody in the primary infertility group and the secondary infertility group had statistical difference compared with the control group ;the posi-tive rate of these 6 kinds of autoimmune antibody in the secondary infertility caused by different etiologies had no statistical differ-ence (P>0 .05) .The positive rate of ANA had no statistical difference between the infertility group and the control group (P>0 .05) ,but the titers of ANA in the experimenter were ≥1∶100(6/7) and most of karyotypes were nuclear coarse (5/7) ,which was differed from the low positive titer in the control group .The positive rate of ANA had statistical difference between the infertility related antibody positive and the infertility related antibody negative in the infertility patients .Conclusion ASAb ,AZpAb AEmAb , AhCGAb and ATAb are related with female sterility .The combined detection of these 6 kinds of antibody can significantly increase the detection sensitivity .

Drinking a great amount of alcohol over a long period of time has serious effect on people's health and their families.It has been the chief concern for many experts to find ways to help people to give up alcohol.Radix pueraria is the most typical traditional Chinese herb to help giving up driking alcohol.Some experts had done some deep-seated pharmacological researches on the effect of puerarin and daidzin,the contents distilled from Radix pueraria,on treating alcohol-dependence disease.The present paper is a general survey of recent developments of this research.

Interleukin 24 ( IL-24) has a good prospect in tumor therapy because it can specifically inhibit proliferation in a variety of tumor cells in vitro and in vivo and induce apoptosis of tumor cells without affecting normal cells .Gene therapies which use recombinant adenovirus as a vector have some limitations that restrict the clinical application of IL-24. In comparison, protein drugs have tremendous advantages .In this paper, the progress in research on IL-24 gene engineering protein is elaborated .

Objective To evaluate the value of united nerve electrophysiological tests in the diagnosis of diabetic peripheral neuropathy (DNP).Methods The quantitative temperature threshold (QTT), including the cold sensation threshold (CST) , thermal sensation threshold (WST), cold pain threshold (CPT) and thermal pain threshold (HPT), sympathetic skin response (SSR) and nerve conduction velocity (NCV) were measured for 85 diabetic patients.Results The abnormal rate of QTT was 84.71％ , significantly higher than that of SSR and NCV (56.47％ and 31.76％ respectively).However, no significant difference was found in the abnormal rate of QTT between the DPN asymptomatic group and DPN symptomatic group (78.85％ and 93.94％ respectively).There was significant difference in the abnormal rate of SSR (48.08％ and 69.70％ respectively) and the abnormal rate of NCV (19.23％ and 51.52％ respectively) between the above two groups(P ＜ 0.05).There was no difference in the abnormal rate of QTT for patients with short or long course of disease (77.77％ and 89.80％ respectively), but significant difference in the abnormal rate of SSR (44.44％ and 65.31％ respectively) and the abnormal rate of NCV (19.44％ and 40.82％ respectively) Conclusion The abnormal rate of QTT was highest in detecting the diabetic patients, and it is not related to clinical symptoms or disease course.However, the abnormal rates of SSR and NCV were related to clinical symptoms and course.It is more sensitive to diagnose DPN using united electrophysiological tests of QTT, SSR and NCV.

Objective To further understand the cellular events of myocarditis,we have examined the myocardial mitochondria structure and activity of ATPase in mice with myocarditis,and observe the interventional effect of different doses of carptopril.Methods Sixty male Balb/c mice were randomly divided into 5 groups:infected coxsackie B3 virus(CVB3)group,infected CVB3 and treated with carptopril(in a dose of 10,30,or 100 mg/kg,twice a day)groups and control group.Captopril was administered after infection.The activity of Na+-K+-adenosine triphosphatase(Na+-K+-ATPase)and Ca2+-adenosine triphosphatase(Ca2+-ATPase)of myocardial mitochondrial as well as the morphological of myocardial mitochondrial were investigated on day 14.Results The activity of mitochondrial Na+-K+-ATPase and Ca2+-ATPase were significantly higher(Pa0.05).Conclusions The favorable effects of captopril exerts on myocyte mitochondria were shown in a dose-dependent manner.Thirty and 100 mg/kg,twice a day captopril protecs the membrane integrity and thus plays a role at the recovery of depressed mitochondrial Na+-K+-ATPase and Ca2+-ATPase activity and also in myocytes injury.

Objective To evaluate the effects of 131I treatment for Graves hyperthyroidism patients with leucopenia and the alteration of WBC levels after treatment.Methods A total of 257 Graves hyperthyroidism cases were retrospectively studied after 131I treatment.Based on baseline WBC count,119 cases with WBC count ＜4.0 × 109/L before 131I treatment were diagnosed with leucopenia and 138 cases had normal WBC.There were no significant differences in age,weight of thyroid,131I uptake rate in 24 h,dose of 131I and course of the disease between the two groups (all t ＜ 0.972,all P ＞ 0.05).WBC,lymphocyte,neutrophil and platelet counts were recorded before and 1,3,6 and 12 months after 131I therapy.The therapeutic effects were graded as clinical cure,improvement,invalidation and hypothyroidism.Statistical analyses,including independent samples t test,x2 test and one-way analysis of variance,were performed using SPSS 13.0.Results The WBC levels in the leucopenia group were (3.49 ± 0.43) × 109/L,(4.06 ±0.98) × 109/L,(4.20 ±1.04) × 109/L,(4.37 ±0.93) × 109/L and (4.88 ± 1.20) × 109/L before 131I treatment and 1,3,6,12 months after 131I treatment,respectively; while,those in the normal WBC group were (5.70 ± 1.08) × 109/L,(5.50 ± 1.14) × 109/L,(5.74 ±0.99) × 109/L,(5.95 ± 1.14) × 109/L and (6.07 ± 1.17) × 109/L,respectively.There was no statistically significant difference of WBC levels before and 1 month after 131 I treatment (t =1.662,P ＞ 0.05) in the normal WBC group,but WBC levels at those timepoints were significantly different in the leucopenia group (t =3.816,P ＜ 0.05).In the leucopenia group,there was no significant change of lymphocytes before and after 131I treatment,while the average neutrophil count showed an increasing trend during the 1,3,6 and 12 months after 131I treatment (F =40.583,t:1.468-11.264,all P ＜ 0.05).The average platelet counts at 6 and 12 months after 131I treatment were (187.80 ± 36.03) × 109/L and (206.88 ± 26.04) × 109/L respectively,which were higher than that before 131I treatment (F =9.735,t =2.604,4.892,all P ＜0.05).In the normal WBC group,there were no statistical differences of WBC changes before and after 131I treatment except for a lower lymphocyte count at 1 month after 131I treatment than that at baseline ((1.79 ± 0.37) × 109/L vs (1.99 ±0.63) × 109/L;F =12.868,t =3.284,both P ＜ 0.05).The treatment effects of the two groups were not significantly different (x2 =0.739,P ＞ 0.05).Conclusions 131I treatment presents similar therapeutic effects on Graves hyperthyroidism patients with leucopenia and those with normal WBC levels.WBC levels in patients with leucopenia may recover to baseline during the post-treatment follow-up.Thus 131I treatment is a safe and effective method for Graves hyperthyroidism patients with leucopenia.

Objective To compare the dissolution behavior between domestic trepibutone tablets and original reference product, and provide a basis for evaluating the quality consistency of generic drugs. Methods Four dissolution media recommended by Japanese Orange Book and a domestic standard dissolution media were selected to determined the dissolution profile,and f2 factor was calculated to investigate the consistency of stripping curves. Results In water,pH 4.0 and pH 1.2,the f2 of domestic formulation and reference formulation was under 50,and the dissolution profile was inconsistent.Dissolution behavior of domestic preparations of different manufacturers was dissimilar.In water,the f2 of domestic preparations of different batches of the same manufacturer was over 99.9,and the dissolution behavior was similar. Conclusion The dissolution method of existing domestic standard can not distinguish the dissolution behavior of different products,and it should be revised and completed.There is still great difference in quality between the domestic preparations and reference preparations.
