Objective To compare the diagnostic clinical significance between loop electrosurgical excision procedure (LEEP) and colposcopical biopsy for cervical intracpithelial neoplasia(CIN). Methods 130 cases of pa-tients diagnosed as CIN under colposcopical biopsy were treated by LEEP in court of gynecology clinic. The conven-tional pathologic diagnosis was recorded in all conization specimens. Results The coincidence rate between colpo-scopical biopsy and LEEP biopsy in CIN Ⅰ, CIN Ⅱ, CIN Ⅲ (not comprised carcinoma in situ) was 55.26%,66.10% ,78.79% respectively;The total coincidence rate was 66.15%. The accuracy of colposcopic biopsy for diag-nosing CINⅢ was higher than that for CIN Ⅰ and CIN Ⅱ,but there was no statistical difference. Conclusion Colpo-scopical biopsy for cervical lesions can be achieved for the frist time the results of pathology, have limitations. LEEP biopsy can compensate partially the deficiency of colposcopic biopsy. In a dear diagnosis of CIN, LEEP biopsy and colposcopical biopsy may complement each other, and achieve thcrpeutic effects.

Vitamin D has a wide range of biochemical effects. Insufficiency/ deficiency of vitamin D increases the risk of insulin resistance by ways of inflammation,adipocytokines,oxidative stress and mitochondria function,it could lead to metabolic disorder of glucose and lipid,which closely relates to the incidence and development of obesity and metabolic syndrome on children. This paper presents the relationship between vitamin D with obesity and metabolic syndrome on children,states the possible mechanisms of regulation of glucose/ lipid metabolism and insulin resistance by vitamin D.

OBJECTIVE:To provide reference for rational application of cephalosporins in the clinic. METHODS:The applica-tion of cephalosporins antibiotics in our hospital during 2010-2014 was analyzed dynamically in respects of consumption sum, DDD,DDC,DDDs,etc. RESULTS:During 2010-2014,the proportion of total consumption sum of antibiotics in total consump-tion sum kept below 30%,and decreased year by year,decreasing from 27.35% in 2010 to 14.70% in 2014. Among antibiotics, the consumption sum and DDDs of cephalosporins were the highest;consumption sum decreased year by year,decreasing from 44.50% in 2010 to 30.49% in 2014;DDDs increased year by year,increasing from 11.00×104 in 2012 to 14.22×104 in 2014. The consumption sum and DDDs of second generation cephalosporins were the highest. The consumption sum of cefotiam ranked the first place;DDDs of cefprozi ranked the first place during 2010-2011,while cefotiam ranked the first place during 2012-2014. DDC of cefpirome was the highest during 2010-2011,and that of cefamandole was the highest during 2012-2014,indicating it was expensive. The serial number ratio of cefprozi and cefuroxim was always >1 during those years,which indicated it was cheap and used frequently;that of most drugs were close to 1. CONCLUSIONS:The application of cephalosporins in our hospital tend to be rational,but the propaganda and supervision of rational use of antibiotics should be further strengthened.

The data may provide a scientific basis for people’s diet structure and medical use.

Objective: To explore the effect of curcumin on proliferation and apoptosis of TK6 human diploid lymphoblastoid cells.Methods: MTT colorometric assay, 3H-TdR incorporation, cell cycle analysis were used to evaluate the effect on proliferation, and morphology microstructure. Flow cytometry was used to detect the effect on apoptosis induction on TK6 cell.Results: Curcumin could inhibit proliferation by blocking transition from G0/G1 to S phase, induce apoptosis in TK6 cells. The effective dose for proliferation inhibition and apoptosis induction is 20 ?mol/L.Conclusion: Apoptosis induction is one of important mechanisms for anti-mutagenic, anti-tumor action of curcumin.

Objective To investitgate the level of polychlorinated biphenyls in retail livestock meat.Methods Totally 28 samples of three kinds of meat including of beef,pork and mutton were collected during Aug-Dec.,2008.Twelve dioxin-like polychlorinated biphenyls(DL-PCBs) and six marker PCBs were extracted by Soxhlet extractor,cleaned up by FMS and qualitative and quantitative analyzedsis by isotope dilution high-resolution gas chromatography/high resolution mass spectrometry(HRGC/ HRMS).Results Levels of total 18 compounds including of 12 DL-PCBs and indicator PCBs in beef,pork and mutton were 1 607.60 pg/g fat,435.82 pg/ g fat,and 505.17 pg/g fat respectively,DL-PCBs concentration were 456.19 pg/g fat,46.37 pg/g fat and 77.50 pg/g fat respectively.Maker-PCBs concentration were 1 151.41 pg/g fat,389.45pg/g fat and 427.67 pg/g fat respectively.The levels of PCB toxicity equivalent(TEQ)(the median value)were:0.84 pg/g fat in beef,0.15 pg/g fat in pork,0.28 pg/g fat in mutton respectively.The TEQ concentration of PCB(median value) was lower than the EU action level limit value.In all samples,PCB118 was the greatest contributor to the total contaminated concentration,and PCB126 was the dominant contributor to toxicity equivalent(TEQ).Six of 28 samples exceeded the limit value of the EU action level.Conclusion The results show that PCBs contamination exists in a city from the six samples exceeding the EU standard limit.It should take measures to explore the cause of contamination of PCBs compounds and control the pollution in order to guarantee food safety effectively.

Objective To investigate the effects of 1,25-dihydroxyvitamin D_3 on the bone metabolism of primary osteoporosis.Methods Female New Zealand white rabbits aged 8 months were ovariectomized bilaterally as models of postmenopausal osteoporosis and they were randomly divided into 4 groups: pseudo-ovariectomized group(Sham group),ovariectomized group(OVX group),calcii gluconas group(OC group),calcii gluconas and 1,25-dihydroxyvitamin D_3 group(OCR group).Both female New Zealand white rabbits aged 3 years and male New Zealand white rabbits aged 4 years were selected as models of senile osteoporosis.They were randomly divided into 3 groups:control group,calcii gluconas group(Calcium group),calcii gluconas and 1,25-dihydroxyvitamin D_3 group(CR group).Rabbits in OC group and Calcium group were given calcii gluconas and in OCR group and CR group were given calcii gluconas and 1,25-dihydroxyvitamin D_3.The bone metabolic biochemical indexes were determined among all the experimental animals after they were given drug for 8 weeks.Results After the experimental animals were given drug for 8 weeks,the serum calcium(Ca),serum phosphorus(P) and alkaline phosphatase(ALP) of OCR group were significantly higher than those of OVX group and OC group(all P

Objective To compare the effects of propofol with thiopentone on preventing riskiness of tracheal intubation. Methods In 224 elective surgical patients under general anesthesia, the riskiness of tracheal intubation was evaluated following the administration of fentanyl 2?g/kg combined with propofol 2.0mg/kg (group P) or thiopentone 5.0 mg/kg (group T) respectively, with multivariate analysis. Results Risk rate was 36. 04 % in group T and 17. 70 % in group P (P 0 .05). Conclusions There is certainly clinical advantage of propofol compared to thiopentone in terms of preventing riskiness of tracheal intubation if hypotension of propofol is unconcerned.

Objective To explore the influence of percutaneous gastrostomy-jejunostomy ( PEG-J) on the nutritional status and prognosis of critically ill patients in ICU .Methods Totally 58 patients who received me-chanical ventilation in the ICU of Changshu No .1 People's Hospital from January 2013 to December 2015 were di-vided into two groups according to random number table:treatment group ( n=28, enteral nutrition by establis-hing PEG-J tube in 120 hours after excluding contraindications );and control group ( n=30, nasogastric tube as the way of giving enteral nutrition and if delayed gastric emptying happened , nasogastric tube would be replaced by nasointestinal tube).The incidence of ventilation-associated pneumonia (VAP) within 28 days, duration of ICU stay, and duration of mechanical ventilation were compared between these two groups .Results The inci-dence of 28-day VAP (7.14%vs.26.67%, P=0.049), duration of ICU stay [ (13.6 ±5.9) d vs.(16.8 ± 4.4) d, P=0.024], duration of mechanical ventilation [ (8.1 ±5.0) d vs.(10.7 ±4.5) d, P=0.041] were significantly lower or shorter in treatment group than in control group .Conclusions The use of PEG-J tube for enteral nutrition in critically ill patients is reliable and safe .It also helps to reduce VAP .
