Pancreatic cancer is a common digestive tract carcinoma. It is strongly occult and lack of early diagnostic indicators, and the patients have quite low survival rates. The pathogenesis of pancreatic cancer remains unclear. It has been reported that smoking, family history, diabetes mellitus and obesity are associated with the incidence of pancreatic cancer; moreover, type 2 diabetes mellitus (T2DM) often occur as a comorbidity. Insulin resistance and compensatory hyperinsulinemia are the main metabolic characteristics of T2DM, which play an important role in the development and progression of pancreatic cancer. The molecular mechanisms of insulin resistance and hyperinsulinemia promoting pancreatic cancer are reviewed in this paper, in order to provide the evidence for the prevention and treatment of pancreatic cancer.

Objective To evaluate the effects of isoflurane anesthesia on the cognitive function and expression of translocator protein 18 kDa ( TSPO) in the brain tissues of aged rats. Methods Twelve pathogen?free male Sprage?Dawley rats, aged 20 months, weighing 500-550 g, were randomly divided into 2 groups ( n=6 each) using a random number table: control group ( group C) and isoflurane anesthesia group ( group I) . The rats inhaled 2% isoflurane in 100% O2 for 4 h in group I, or 100% O2 for 4 h in group C. The rats underwent Morris water maze test at 24 h after anethesia. The escape latency and frequency of crossing the original platform were recorded. Then the rats were sacrificed, and the hippocampus and cerebral cortex were isolated for determination of the expression of TSPO and Iba1 by Western blot and quantitative real?time reverse transcriptase?polymerase chain reaction. Results Compared with group C, the escape latency was significantly prolonged, the frequency of crossing the original platform was decreased, and the expression of TSPO and Iba1 protein and mRNA in the hippocampus and cerebral cortex was up?regulated in group I ( P<0. 05 ) . Conclusion Isoflurane anesthesia results in decreased cognitive function through up?regulating the expression of TSPO in the brain tissues of aged rats.

Objective To compare and analyze the clinical effect and adverse reaction of oral azithromycin,oral and intravenous erythromycin on the treatment of mycoplasma infection in respiratory tract.Methods In our hospital in January 2015～March 2016 year,clinical datas of 110 cases with mycoplasma infection in respiratory tract in children were analyzed retrospectively.The total cases were randomly divided into the oral azithromycin treatment group(38 cases),oral erythromycin treatment group(36 cases)and erythromycin intravenous group(36 cases).The therapeutic effects and the adverse reactions were evaluated in the three groups.ResultsThe effective rate in the oral azithromycin group was significantly higher than that of the two other groups.The time of fever fading,rales and cough disappearance and the hospitalized day in the the oral azithromycin group were significantly shorter than that in the other two groups.Serum IL-8,TNF-alpha and hs-CRP level and the adverse reaction rate in the the oral azithromycin was significantly lower than that in the other two groups.The differences of all above the indexes were statistically significant(all P<0.05),the above index in the oral erythromycin group and erythromycin intravenous group was no statistical significance.Conclusion Compared with different medication route of erythromycin,it can get better results which oral azithromycin was used on the treatment of children with respiratory tract mycoplasma infection,the adverse reactions rate is lower,is a safe and effective treatment.

Kinesin-2 family proteins, including KIF3A, KIF3B, KIF3C and KIF17, are members of the kinesin superfamily motor proteins , which transport various proteins and vesicles in the cell and play diverse biological functions . Recently, studies on members of kinesin-2 family proteins suggest that they play fundamental roles during ciliary transport , whose defects can lead to abnormal cilia development , the major cause of human ciliopathies .In this review , we will sum-marize the functions of this motor protein family during ciliogenesis and focus mainly on their roles in the development of model organisms .

ObjectiveTo evaluate the efficacy of preemptive analgesia with parecoxib for acute postoperative pain after pulmenary lobectomy.MethodsSixty ASA Ⅱ or Ⅲ patients of both sexes aged 20-64 yr weighing 50-80 kg undergoing elective pulmonary lobectomy were randomly divided into 3 groups ( n =20 each): control group (group C); group A (parecoxib 40 mg was injected iv at 20 min before surgery) and group B (parecoxib 40 mg was injected iv when skin was sutured).Patient controlled intravenous analgesia (PCIA) with sufentanil and ramosetron (continuous background dose 2 ml/h,bolus dose 0.5 ml,lockout time 15 min) was used after surgery.When VAS score ＞ 3,iv bolus of tramadol 1-2 mg/kg was injected as rescue medicine.Agitation condition was observed after operation.The number of successfully delivered doses and the number of attempt were recorded.The consumption sufentanil and the number of rescue medicine were recorded during 24 h after surgery.ResultsThe incidence of postoperation agitation,number of successfully delivered doses and number of attempt,consumption sufentanil and number of rescue medicine were significantly lower in groups A and B than in group C.The consumption sufentanil and number of rescue medicine were significantly lower in group A than in group B ( P ＜0.05).ConclusionParecoxib can use for preemptive analgesia in patients after thoracic surgery,reduce the complication during anesthesia recovery and the opioid analgesics consupmtion.

In order to evaluate the factor. which affect the five year survival rate and prognosti c factors of the early carcinoma of the esophagus and the gastric cardia treated with endoscopic Nd : YAG laser therapy , thirty-three patients were followed. Of the 33 patients , 32 ( 97% ) cases were cured , resul- ting in the disappearance of the cancer cells. They were followed up for 3 3- 78 months , with a mean of 55. 3 months. The survival rate of the 32 patients treated with endoscopic laser was computed with the Product limit estimate method ,and was compared with the natural history of early superficial carcinoma . of the esophagus and the gastric cardia. The five year survival rate was in 97% of the 32 patients treated with laser therapy ,in contrast to 67% (P

Naive and chronically infected C57BL/6 mice were challenged percutaneously over the ear pinna with Schistosoma japonicum cercariae. After 15 hours, the number of EOS increased significantly in the skin of chronically infected mice. Inflammatory cells aggre-gated in the vicinity of schisto.somula or entrapped intact and disintegrated schistosomula, forming granulocytic micro-abscesses in both groups. Ultrastructure studies revealed that flattened EOS tightly attached to the schistosomulum surface and degranulated. Local tegument damage occurred in the area of attacbment. NEU adherence did not seem to be as intimate as EOS, and degranulation was not seen. The tegument of the attached schis-tosoniulum remained normal. The result suggested that EOS appeared to be the efficient killer cell against skin phase schistosomula of S. japonicum (Figs. 1-6).

ObjectiveTo evaluate clinical efficacy ofYupingfeng Granules combined with western medicine for children with recurrent respiratory tract infection (RRTI).Methods CNKI, VIP, WANFANG DATA, SinoMed, PubMed, Embase, and Cochrane Library were searched for the randomized controlled trials (RCTs) that investigated the clinical and immune effects ofYupingfeng Granules in children with RRTI from inception to October 2015. Two researchers independently screened studies according to the inclusion and exclusion criteria, extracted data and evaluated the methodological quality of included studies. Then Meta analysis was performed through the software RevMan 5.3.Results A total of 8 articles involving 550 patients were included. The results of Meta analysis showed effective rate ofYupingfeng Granules combined with western medicine for children with RRTI [OR=4.16, 95%CI (2.49, 6.95),P<0.000 01], IgA level [MD=0.52, 95%CI (0.26, 0.78),P<0.000 1], IgG level [MD=2.75, 95%CI (1.25, 4.25),P=0.000 3], CD4+ level [MD=6.15, 95%CI (4.76, 7.54),P<0.000 01], CD4+/CD8+ level [MD=0.36, 95%CI (0.25, 0.47),P<0.000 01]. All of the above were superior to single western medicine treatment. There was no statistical significance in levels of IgM and CD8+(P>0.05). ConclusionYupingfeng Granules combined with western medicine can improve effective rate, antibody level and T-cell level in the treatment of children with RRTI. The overall clinical efficacy is better than single western medicine treatment. However, RCTs with large samples, multiple centers and high quality are needed for further verification.
