Objective To investigate the level of serum retinol-binding protein 4 (RBP4) and related factors in chronic hepatitis C (CHC). Methods Fifty-six patients with CHC (CHC group) and 35 healthy volunteers (control group) were selected. Serum RBP4 level was measured by ELISA method.Fasting blood glucose ( FBG ), triglycerides (TG), total cholesterol ( TC ), alanine aminotransferase (ALT),γ-glutamyl transpeptidase (γ-GT) were measured, HCV-RNA level was tested by qualitative polymerase chain reaction(q-PCR). Results There were no significant difference in FBG, TC,TG, γ-GT between two groups (P ＞ 0.05 ). Serum RBP4 level in CHC group [(33.38 ± 6.43 ) mg/L] was higher than that in control group [(26.11 ± 3.35) mg/L](P＜ 0.01),the CHC patients with ALT normal (26 cases) had significantly higher RBP4 level [( 38.96 ± 4.09) mg/L] compared with ALT abnormal [30 cases, ( 28.53 ± 3.43 ) mg/L](P ＜ 0.01 ). ALT level was negative with RBP4 in CHC group (r = -0.6368, P ＜ 0.05 ). Conclusion Serum RBP4 level is significantly associated with CHC and negatively correlated with ALT level,but not associated with FBG, TC,TG, γ-GT and HCV-RNA.

As a method of choice in the treatment of ampulary carcinoma,pancreaticoduodenectomy often demands open procedure.With the development of minimally invasive techniques,laparoscopic pancreaticoduodenectomy was realized in recent years.Because laparoscopic pancreaticoduodenectomy is high technique-demanding,its popularization is restricted.With flexible robotic arnls and three-dimensional imaging,Da Vinci surgical system has overcome the shortcomings of traditional laparoscope to some extent.In March 2010.a 60-year-old female patient with ampulary carcinoma underwent Da Vinci surgical system-assisted pancreaticoduodenectomy at the Southwest Hospital.The mean operation time and blood loss were 490 minutes and 450 ml respectively,and no blood transfusion was required.Out-of-bed activity began shortly after the operation.The gastric tube was removed and fluid diet was given on postoperative day 3.The patient was discharged on postoperative day 10 without incidence of complications.The Success of this case preliminarily demonstrats that Da Vinci snrgical system-assisted pancreaticoduodenectomy is safe and feasible.

To examine the relationship between genetic variants in the interleukin-6 receptor gene and obesity. The result showed that the carriers of Asp358 homozygotes had higher risk in developing obesity when compared with Ala358 homozygotes (OR = 1.32,95% CI 1.07-1.68, P = 0. 041). Interleukin-6 receptor gene pulymorphism was significantly associated with obesity.

Objective To investigate the changes of PPARr mRNA and protein expressions in rats with ANP. Methods 36 rats were randomly divided into sham group and ANP group. The rats were sacrificed 3 h, 6 h,12 h after ANP induction, the levels of serum amylase were measured, the pancreatic pathological changes were determined and the expressions of pancreatic PPARr mRNA and protein was examined by RT- PCR and immunohistochemistry. Results In ANP group, the level of serum amylase at 6h was (7170.83± 1635.59) U/L, the scores of pathological changes were 6.67±1.03 and 13.00±2.36, which were much higher than those of sham group (P<0.01) ; the PPARr mRNA expression was 0.18±0.05, and there were no obvious differences compared with that of sham group (0.22±0.03 ) ; PPARr protein expression was 4.17 ±0.98, which was significantly higher than that of sham group (1.83±0.71, P<0.05). Conclusions Inflammatory injury resulted in increased deactivation of pancreatic acinar PPARr, meanwhile PPARr gene expression was inhibited by feedback.

Objective To compare the risk of tumor invasion and metastasis under paravertebral block (PVB) combined with general anesthesia versus general anesthesia in the patients undergoing radical resection for lung cancer performed via video-assisted thoracoscope in terms of plasma concentrations of vascular endothelial growth factor (VEGF) and matrix metalloproteinase-9 (MMP-9).Methods Forty ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 30-64 yr,with body mass index of 18-25 kg/m2,scheduled for elective radical resection for lung cancer performed via video-assisted thoracoscope,were randomly divided into 2 groups (n =20 each) using a random number table:general anesthesia group (group G) and PVB combined with general anesthesia (group PG).PVB of T4-7 was performed successfully with local injection of 0.375％ ropivacaine 5 ml before induction of anesthesia.Double-lumen endotracheal tube was placed after induction of anesthesia,and the patients were mechanically ventilated.Anesthesia was maintained with inhalation of sevoflurane (end-tidal concentration 1％-2％),and intravenous infusion of remifentanil 0.2-0.3 μg · kg-1 · min-1,and intermittent intravenous boluses of atracurium.Before anesthesia and at 24 h after surgery,the venous blood samples were collected for measurement of plasma concentrations of VEGF and MMP-9.Results The plasma VEGF and MMP-9 concentrations were significantly lower after surgery in group PG than in group G.Conclusion PVB combined with general anesthesia significantly decreases the risk of tumor invasion and metastasis in the patients undergoing radical lung cancer resection performed via video-assisted thoracoscope in comparison to general anesthesia.

Objective To observe the clinical efficacy of Wenshen Xiaochuan Paste Recipe (WXPR) in preventing bronchial asthma, and to explore the mechanism. Methods Eighty patients were randomly divided into treatment group and control group. Each group had 40 patients. The control group was treated by conventional western medicine such as inhalation of steroid, and the treatment group was given oral use of WXPR based on the treatment for the control group. Treatment for both groups covered 60 days, and the follow-up lasted 10 months. The clinical outcomes included the clinical efficacy and immune indexes of peripheral blood T lymphocyte subsets CD3+, CD4+, CD8+and CD4+/CD8+ratio, and the serum IgE level. Results (1) After treatment and 12 months later, the scores of asthma control test (ACT ) in the two groups were increased obviously as compared with those before treatment, and there were statistically significant differences (P<0.05 or P<0.01) . The differences of ACT scores between the two groups were insignificant after treatment ( P>0.05) , but were significant ( P<0.05) 12 months later. (2) Within one year after treatment, the frequency of acute asthma attack was decreased in both groups (P<0.05 compared with that before treatment), and the treatment group had better effect on decreasing the attack frequency than the control group (P<0.05). (3) After treatment, the serum IgE, CD4+level, and CD4+/CD8+ ratio were decreased significantly, while CD8+ level was increased in the treatment group, and there were statistically significant differences ( P<0.05 compared with those before treatment). However, the differences of immune indexes in the control group were insignificant before and after treatment ( P>0.05). The improvement of immune indexes in the treatment group was superior to that in the control group ( P<0.05). Conclusion WXPR has good clinical efficacy in preventing and treating bronchial asthma. The mechanism is related with the inhibition of airway inflammation and improvement of immune function probably through regulating T lymphocyte subsets and lowering serum IgE level in asthma patients.

Pulmonary cyst is a relatively common benign lesion.It is easy to be misdiagnosed when the cyst complicated with infection.Tnis paper reported a case of a giant traumatic pulmonary cyst (diameter 10 cm) combined with chronic infection.Firstly,the patient was diagnosed as cholesterol pleurisy after undergoing thoracoscopic biopsy.With repeated pleural effusion,the patient was scheduled for right anterolateral thoracotomy,which showed a thin-walled cyst (10 cm in diameter) attached to parietal and diaphragm,with the stem of cavity originated from the right lower lobe after the cyst cavity was dissociated.Pathological examination revealed that it was apseudocyst,which could be diagnosed as traumatic pulmonary cyst combined with chronic infection according to history of trauma.After undergoing right lower lobectomy and stripping of fiberboard,the prognosis was good.Traumatic pulmonary cyst,which was discovered interval 10 years after chest trauma,was rare.Traumatic pulmonary cyst combined with cholesterol cystic fluid was very rare.Huge pulmonary cyst complicated with infection was easily misdiagnosed as loculated pleural effusion.Therefore,to be correct diagnosis and treatment,clinician must carefully ask medical history.In addition,early image examination should be considered in those patients with chest trauma whether there are clinical symptoms or not.
