Metabolic syndrome( MS) is a group of clinical symptoms,which is based on the pathophysiol-ogy of insulin resistance that mainly includes obesity,hyperglycemia,hypertension,dyslipidemia,nonalcoholic fatty liver disease and other components.In recent years,many studies have suggested that the occurrence of colorectal cancer( CRC) is closely related with the MS components.This article reviews the research progress on the associa-tion between the major components of MS and the pathogenesis of CRC.

Objective To determine the predictive value of fetal fibronectin (fFN) alone or combined with cervical length (CD for preterm birth in pregnant women with preterm labor. Methods Pregnant women were collected from three hospitals. fFN level in discharges from the posterior fornix and the CL under vaginal ultrasound scan were measured for all subjects who presented with preterm labor between 24-34+6 gestational weeks with intact membranes, cervical dilation

Objective To evaluate the efficacy and safety of combination therapy of Endostar and oxaliplatin plus S-1 ( SOX regimen) in patients with advanced Primary carcinoma of the liver. Methods 32 advanced primary liver cancer patients admitted from February 2012 to August 2014 were assigned to SOX regimen as systemic chemotherapy: oxaliplatin 130 mg/m2 iv d1; S-1 (80 ~ 120 mg, twice-daily) for 14 days; 150 mg Endostar which was dissolved in 210 mL normal saline for 120 h durative transfusion. Treatment was repeated every 21 days. Objective clinical efficacy and adverse effect was assessed every 2 cycles. Serum alpha fetoprotein (AFP) level was also monitored according to the schedule. Results All 32 patients were available to be assessed, the objective response rate (ORR), disease control rate (DCR) ,the clinical benefit response rates (CBR), 1 year survival rate was 15.6%, 46.9%, 56.3%, 58.3% respectively. The serum AFP respond rate was 19.4%. Major adverse effects were myelosuppression and fatigue , mostly graded at 1 ~ 2. There were no treatment-related death. Conclusions These preliminary results suggest that continuous intravenous pumping of Endostar combined with SOX regimen could provide survival benefits with tolerable adverse effects.

OBJECTIVE:To observe therapeutic efficacy and safety of S-1 capsules combined with recombinant human end-ostatin in the treatment of middle and advanced primary liver carcinoma. METHODS:Totally 94 patients with middle and advanced primary liver carcinoma in the First College of Clinical Medical Science of China Three Gorges university during Feb. 2012-Dec. 2014 were divided into combination group(48 cases)and control group(46 cases)according to random number table. Both groups were given S-1 capsules 40-60 mg orally within 30 min after breakfast and supper. Combination group additionally received Recom-binant human endostatin injection 150 mg added into 0.9%Sodium chloride injection 210 mL with portable micro pump for continu-ous pump of 120 h. A course involved 14 d treatment and 7 d interval. Short-term objective therapeutic efficacy,clinical benefit re-sponse (CBR) and ADR were evaluated after 2 courses. Disease progression time and average survival period were compared be-tween 2 groups. RESULTS:Objective response rate,disease control rate,disease progression time and average survival period of combination group were 14.6%,66.7%,(5.5 ± 1.3) months,(10.7 ± 3.8) months;those of control group were 8.7%,45.6%, (4.8±1.2)months,(8.9±3.3)months,with statistical significance between 2 groups(P<0.05). CBR rate of combination group (79.2%)was significantly higher than control group(52.2%),with statistical significance(P<0.05). There was no statistical sig-nificance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:S-1 combined with recombinant human end-ostatin show good therapeutic efficacy and tolerance for patients with middle and advanced primary liver carcinoma,and do not in-crease the incidence of ADR.

Objective To investigate the changes in prevalence of nutritional risk and undemutrition in patients with head and neck cancer during radiotherapy.Methods In this longitudinal observational study,a convenience sampling method was used to recruit patients with head and neck cancer who were receiving radiotherapy in Beijing Cancer Hospital.Nutritional Risk Screening 2002 (NRS 2002) was applied to assess the prevalence of nutritional risk in the patients,and Patient-Generated Subjective Global Assessment (PG-SGA) and body composition test to determine the prevalence of malnutrition (undernutrition) before,during and after radiotherapy.Results 56 patients finished the three follow-up exams.Along with the progress of radiotherapy,the scores of NRS 2002 increased gradually (1.64±1.09 vs.2.30 ±1.06 vs.3.14 ±1.07,x2 =46.639,P＜0.001),and the prevalence of nutritional risk also increased gradually (21.43％ vs.37.50％ vs.71.43％,x2 =29.700,P ＜0.001);the total scores of PG-SGA [1 (1-13) vs.6 (1-15) vs.12 (1-18),x2 =63.206,P＜0.001] and dimensions of weight [0 (0-4) vs.1 (0-4) vs.3 (0-6),x2 =40.798,P＜0.001],intake [0 (0-2) vs.1 (0-2) vs.2 (0-4),x2=64.707,P＜0.001] and symptoms [0 (0-7) vs.2 (0-10) vs.6 (0-11),x2 =61.562,P ＜ 0.001] all increased gradually with statistical significance.The prevalence of malnutrition in different stage of radiotherapy were significantly different (x2 =64.999,P ＜ 0.001).The body composition analysis in 40 patients showed that all the indicators of body composition decreased significantly along with the progress of radiotherapy.There was a great loss in patients' body weight during radiotherapy,especially the fat-free mass.Conclusions The prevalence of nutritional risk and undernutrition may increase in patients with head and neck cancer during radiotherapy.Lean body mass accounted for most of the weight loss.We should pay more attention to those patients' nutritional status during radiotherapy.

OBJECTIVE To investigate the resistance of clinical isolated strains to the commonly used antibacterials in our hospital 2007-2008.METHODS Clinical isolated strains and sensitivity of drugs were detected by ATB system.The result of drug sensitivity was judged by CLSI standard and analyzed with statistical software WHONET5.3.RESULTS Altogether 3150 strains bacteria were isolated,17.4% were Gram-positive strains and 82.6% were Gram-negative strains,and the top five isolates were Pseudomonas aeruginosa,Escherichia coli,Klebsiella pneumoniae,Acinetobacter baumannii,and Staphylococcus aureus.The reasistance rate of Gram-positive strains to minocycline was 15.4%.Five VRE strains were isolated.Various Enterobacteriaceae bacteria were sensitive to imipenem meropenem,cefoperazone-sulbactam and piperacillin-tazobactam,and their rate was 86.5% to 97.7%.Some of Acinetobacter and Stenotrophomonas maltophilia were multidrug resistant.CONCLUSIONS It is serous that multidrug resistance of isolated strains of the patients exists in our hospital.

Objective To evaluate the feasibility of transfection of Sonic hedgehog gene (SHH)into bone marrow mesenchymal stem cells(BMMSC).Methods After the SHH gene was transfected into BMMSC by electroporation apparatus,the transfection rate was evaluated by fluorescence inverted microscope.The growth curves of untransfected and transfected BMMSC were drawn,respectively,to observe the influence of transfection on cells.The expression of SHH gene in the BMMSC was detected by PCR,RT-PCR,Western-blot analyses.Results Through fluorescence inverted microscope,the observed transfection rate was appropriately 30％,PCR showed a obvious increase of SHH expression in transfected cells than that in untransfected cells,and it is quantified by qPCR for appropriately 7 times.Western-blot further demonstrated that the SHH protein expression in transfected cells had a distinct increase.However,it was observed that the exponential phase of BMMSCSHH growth curve delayed.The growth curves of both overlap 12 days after transfection.Conclusions This electroporation method can transfect exogenous SHH gene into BMMSC sufficiently with the effective protein expression in BMMSCSHH.It is the foundation of further research of genetic therapy for ischemic heart disease.

Objective To investigate the clinical effect of McDonald cervical cerclage and the affecting factors. Methods Between January 2002 to December 2013 in Peking University First Hospital we performed McDonald cervical cerclage for 116 single pregnant women. They were defined as the successful group who deliveried the live babies after 28 weeks after the cerclage and the failure group who deliveried in the second trimester. According to the surgical indications they were divided into preventive cerclage group and therapeutic cerclage group. Then we analyzed the curative effect and the affecting factors in the groups. Results (1) In the 116 cases, 12 cases (10.3%) failed, and 104 cases (89.7%) succeeded. In the successful group, 37 cases (35.6%,37/104) deliveried pretermly and 67 cases (64.4%) deliveried termly. And there were 56 cases of vaginal delivery (53.8%), and 48 cases (46.2%) of cesarean section. (2) Among the 116 cases, 48 cases (41.4%) were included in prophylactic cerclage group, the gestational age was (16.3± 2.2) weeks, 68 (58.6%) cases were included in therapeutic group, the gestational age was (24.0±2.2) weeks. The operation time was (22±9) minutes in preventive group and (24±13) minutes in therapeutic group,there was no statistical difference between the two groups (P>0.05). Live-birth rate between preventive cerclage group and therapeutic cerclage group was no statistically significant difference (P>0.05). The term birth rate (72.9%, 35/48) in preventive group was higher than that in therapeutic group (47.1%, 32/68), the difference was statistically significant (P<0.01). Neonatal hospitalization rate was lower in preventive group (14.6%, 7/48) than therapeutic group (36.8%, 25/68) , the difference was statistically significant (P< 0.01). (3) In the failure group placental pathology was examed in 7 cases. The placental tissue showed a large number of neutrophils infiltrating in 6 cases (6/7). In the successful group, 27 pregnant women deliveried between 28 to 33+6 weeks (26.0%,27/104), 10 pregnant women deliveried between 34 to 36+6 weeks 10 cases (9.6%, 10/104), 67 cases deliveried after 37 weeks (64.4%, 67/104). A lot of factors including maternal age, the previous cervix operation history, perioperative application of progesterone, operation time and preoperative invasive procedure were compared between the successful group and the failure group. Only maternal age and preoperative invasive proedcure were statistically significant (P<0.05) and the others had no statistical significance (P>0.05). (4) There were 68 cases in the therapeutic group, 7 cases failed, and 61 cases succeeded;the preoperative cervical os in failure group [ (21 ± 20) mm] was wider than that in successful group [(14±5) mm], the difference was statistically significant (P<0.05);and preoperative vaginal ultrasound measurement of cervical canal length were (18 ± 8) mm versus (19 ± 10) mm, there was no statistically significant difference (P>0.05). Conclusions The McDonald cervical cerclage for cervical incompetence is a simple, safe and high successful rate of intervention measures. The term labor rate of prophylactic cervical cerclage was higher than that of the therapeutic cerclage. Older maternal age and preoperative invasive procedure may be the risk factors for cerclage. The infection may play an important factor leading to the failure of McDonald cervical cerclage.

Objective To investigate the correlation between stenosis of middle cerebral artery (MCA) and cerebral perfusion in patients with unilateral MCA stenosis.Methods Computed tomography perfusion (CTP) was performed in 34 patients with unilateral MCA stenosis,admitted to our hospital trom April 2012 to March 2013.The CTP parameters of mean transit time,cerebral blood flow,cerebral blood volume and time to peak were measured in regions supplied by anterior cerebral artery,MCA and posterior cerebral artery.All patients were divided into severe stenosis group and moderate stenosis group; the correlation between MCA stenosis and cerebral perfusion was analyzed.Results A decreased perfusion was detected in 25 patients (73.5％),and it was more likely found in the severe stenosis group (18/20,90％) than that in the moderate stenosis group (7/14,50％,P=0.017).The degree ofMCA stenosis was positively correlated with the changes of cerebral perfusion (r=0.381,P=0.026).The ratio of patients with transient ischemic attack (TIA) between the normal cerebral perfusion group and decreased cerebral perfusion group had statistical difference (11.11％ vs.72.00％,P=0.004).Conclusion Cerebral perfusion is significantly correlated with the severity of MCA stenosis in unilateral MCA stenosis patients; the proportion of TIA in the low cerebral perfusion patients is higher than that in the normal cerebral perfusion ones.
