A total of 185 patients with type 2 diabetes mellitus (T2DM) were consisted of male group (n =95) and postmenopausal female group (n =90).The parameters of fasting plasma glucose,HbA1c,fasting insulin,fasting C peptide,homeostasis model assessment insulin resistant index (HOMA-IR) and β-cell function (HOMA-β),blood lipid,body mass index,and waist to hip ratio were collected and analyzed by Pearson correlation analysis and stepwise multiple regression analysis.The relationships between osteocalcin and these parameters were investigated.The results revealed that osteocalcin was negatively correlated with HbA1C (P＜0.05),and osteocalcin was an independent relevant factor affecting HbA1Clevels.Osteocalcin may be involved in the regulation of glucose metabolism in T2DM.

Objective To observe the effects of blood pressure by intravenous infusion of different doses ofoxytocin in cesarean section.Methods Sixty full-term pregnant women undergoing cesarean section with continuous epidural anesthesia were divided into three groups by random digits table method with 20 cases each:group A,B and C.Three groups were injected 10 U oxytocin in uterine muscle after infant delivery.Group A,B and C received 5,10 and 20 U oxytocin (sodium lactate ringer,500 ml) continuous intravenous infusion at the speed of 10 ml/min.If happened uterine contractions bad,they were sublingual administering 0.2 mg misoprostol.If happened severe hypotension,they were intravenous injected 5 mg ephedrine.The change of mean arterial pressure (MAP) and heat rate before anesthesia (T0),after fetal childbirth (T1),5 m in (T2),10 min (T3),30 min (T4) after infusion of oxytocin and the dosage of ephedrine and misoprostol were recorded.Results There were no significant differences in MAP and heart rate at every time point between group A and B (P＞ 0.05).MAP decreased and heart rate increased in group C at T2,T3 compared with those in group A and B,and there were significant differences (P＜ 0.05).The number of cases of sublingual misoprostol were increased in group A (7 cases) compared with that in group B (2 cases) and group C(1 case).The 8 patients injected ephedrine in group C were more than group A(1 case) and group B (3 cases).Conclusion Cesarean section after the delivery of the fetus in the uterus muscle injection of oxytocin 10 U,after 10 U of oxytocin added 500 ml sodium lactate ringer injection at the speed of 10 ml/min intravenous infusion has little effect on the blood pressure and heart rate,and has good uterine contractions.

Meningioma of unusual age of onset, location, histogenesis and histologic type is reported. The patient, 4 year-old girl, had an intradural spinal meningioma arising from lumbar nerve root with no dural attachement. The meningioma revealed glycogen-rich, clear cell type with extensive and blocky hyalinization of the stroma. The tumor shared common fibrous sheath with attached lumbar nerve, and nerve fibers were scattered within the tumor. Ultrastructurally, the tumor cells had abundant glycogen particles, intermediate filaments and intercellular desmosomes. Hyalinized material revealed large amianthoid collagen fibers.

Objective To evaluate the application value of cardiopulmonary ultrasound(CPUS) in patients with interstitial lung diseases(ILD).Methods Ninety patients with clinically diagnosed interstitial lung diseases and 30 healthy subjects were included in this study.The conventional echocardiographic parameters and right ventricular free wall longitudinal strain (RVLS_FW) were measured in all patients and healthy subjects.The degree of pulmonary fibrosis or the disease severity of each ILD patient was scored using a semi-quantitative scoring method.Patients’ pulmonary function parameters and clinical outcome score (GAP score) were recorded.Fourteen patients belong to other types of ILD and 19 patients with incomplete clinical data were unable to perform GAP scoring,finally 57 patients' clinical and ultrasonographic parameters were measured.On the basis of the pulmonary arterial systolic pressure (PASP) obtained by Doppler echocardiography,90 patients were divided into two groups:ILD patients with pulmonary hypertension(ILDpH,PASP ≥36 mmHg,1 mmHg =0.133 kPa) and ILD patients without PH (ILDNpH,PASP＜ 36 mmHg).Comparsion between ILDpH,ILDNpH and healthy subjects were then evaluated.According to the GAP score,all cases were divided into three groups:low risk,moderate risk and high risk.Statistical analysis was performed to examine the relationship between CPUS parameters and clinical parameters.Results ①Compared with ILDNpH patients,ILDpH patients had significantly lower right ventricular function,wider basal right ventricular diameter (RVD),proximal right ventricular outflow diameter (DRvor1) and right pulmonary artery diameter (DRPA).Compared with healthy subjects,ILDNpH patients had mildly lower right ventricular function and wider left pulmonary artery diameter (DLPA) and right ventricular outflow tract dimensions at the distal or pulmonic valve (DRvoT2).②A good correlation was found between lung ultrasound (LUS) scores and pulmonary function parameters,especially diffusion capacity for carbon monoxide of the lung(DLco)(r =-0.68,P ＜0.001).③With the increased risk of patients,the right ventricular function was gradually decreased,DRVOT2,DRPA,DLPA were gradually widened,and the lung ultrasound score was gradually increased.A weak correlation was found between GAP scores with RVLS_FW,LUS scores,DRpA(r =0.44,0.34,0.31,P ＜0.05).Conclusions CPUS parameters are useful in the assessment of interstitial lung disease and could reflect the prognosis of ILD patients to some extent.Therefore,on the basis of GAP scores,addition of RVLS_FW and LUS score will be more helpful to evaluate the prognosis ofILD patients.

Objective To evaluate the outcomes of open reduction and internal fixation of complex tibial plateau fractures with improved three combined approaches.Methods In the period from July 2014 to February 2016,7 complex tibial plateau fractures underwent surgical treatment.These patients included 5 male and 2 female,aged from 24 to 68 years old (average,39.7± 15.3 years).According to Schatzker classification,they were all of type V.And all of type 41B-3.1 by AO/OTA classification.All these fractures were exposed and reduction via three combined approaches.First let the patients lied in lateral prone position,expose the anterolateral and the posterolateral of the tibia1 plateau,and fix the fractures of the posterior in the posterolateral approach,then fix the fractures of the lateral in the anterolateral approach.Then turn the patients to supine position,fix the fractures of the medial in the anteromedial incision.All patients received regular reexamination.The knee function was evaluated at the final follow-up using The Hospital for Special Surgery (HSS) score,the activity of the knee was evaluated by Lysholm score,and the stability of the knee was checked by Lachmantest and Pivot-shift test.The tibial plateau angle,the posterior slope angle and Rasmussen X-ray score were assessed on the X-ray films.Results The average time of operation is (3.3±0.9) h,and the hemorrhage volume in operation was (341± 106) ml for the 7 patients.The wounds of 6 patients healed by (11.8± 1.3) days,while the wound of the rest one of them occurred fat liquefaction after operation who is very fat (BMI ＞ 30) and suffered from diabetes.His wound healed by 21 days.These patients obtained follow-ups of 8 to 14 months (average,11.4±2.8 months).The average full weight-bearing time was 2-3 months (average,2.5±0.4 months).The fractures healed after 8 to 16 weeks (average,11.1 ±2.8 weeks).No displacement of the fractures or breakage of the implants occurred in our series.Nobody has activity limitation of the knee or pain because of the implant,and no never symptoms were noted postoperatively,so we would not take out the implant for these patients.The mean HSS score was 93.1±4.8 (range,from 85 to 100) at the final follow-up,and the excellent rate is 100％.The Lysholm score was 97.1±3.6 (range,from 90 to 100) at the final follow-up.The Lachman test and the Pivot-shift test were negative in our patients,and the mean knee flexion was 128.6±12.8°(range,from 105°to 140°).The fractures were all anatomical reduction by the X-ray after operation,and there had being no displacement of the fractures or breakage of the implants occurred during the follow-up period.The mean posterior slope angle was 8.29±2.87° (range,from 4 °to 12°),which was 8.71±2.63° (range,from 5 °to 14°) 6months after operation.The mean tibial plateau angle was 86.00± 1.41° (range,from 84 °to 88°),which was 86.43± 1.62° (range,from 84 °to 89°) 6 months after operation.The mean Rasmussen X-ray score was 16.86±1.57 (range,from 14 to 18),which was 16.57±1.51 (range,from 14 to 18) 6 months after operation,and the excellent rate are 100％.Conclusion For the complex tibial plateau fractures which simultaneous involved the medial,the lateral and the posterior,the improved three combined approaches showed the advantages of the convenient operation,the satisfactory results of reduction and fixation,and the less trauma and secondary damage,and could be worth for clinic.

Objective To investigate the characteristics of intestinal flora in infants with different feeding patterns.Methods Sixty-two cases of health infants(30-120 d)were divided into 4 groups according to their feeding patterns:breast feeding,imported powder milk feeding,domestic powder milk feeding and mixed feeding.Samples of their fresh feces in each group were collected and divided into sections equally:the bifidobacteria were isolated in anaerobic box and the number was counted for one section;for the other section,total DNA of intestinal flora was extracted and enterobacterial repetitive intergenic consensus (ERIC) fingerprints were amplified with the method of ERIC-PCR.After that,the specific bands observed in different groups were cloned and sequenced and alignmented.Results The colonies of bifidobacteria were more in breast feeding and mixed feeding groups[(9.10 ± 1.33) cfu/g;(8.62 ± 1.35) cfu/g]than those in domestic powder milk feeding and imported powder milk feeding groups[(7.62 ± 1.22) cfu/g;(7.32 ± 0.80) cfu/g,t =3.23,P ＜ 0.05];while there was no significant difference between breast feeding and mixed feeding groups,and between 2 powder milk feeding groups.Two specific bands were found from the ERIC fingerprints (A:1 100 bp mainly in breast feeding,domestic powder milk feeding and mixed feeding groups;B:1 000 bp mainly in imported powder milk feeding group).Sequencing and analysis of Basic Local Alignment Search Tool showed that homologous bacteria of A and B fragments were bifidobacterium longum.The encoding protein of A fragments might be related to the enzymes of carbohydrate metabolism,and B fragments were related to the enzymes of protein metabolism.Conclusions The colonies of bifidobacteria in intestinal tract are more in breast feeding and mixed feeding infants than those in formula feeding groups.The distribution of intestinal flora in domestic powder milk feeding infants is more similar to that of the breast feeding infants.

Objective To further understand factors that influence health-related quality of life (HRQOL) in patients with ulcerative colitis (UC),especially the role of perceived stress and coping modes in Chinese patients with UC.Methods This study was a cross-sectional study.Patients with UC were recruited from July 2013 to September 2014 in Peking Union Medical College Hospital.HRQOL was measured using the inflammatory bowel disease questionnaire (IBDQ).Perceived stress was measured by Perceived Stress Scale (PSS).Coping strategy was evaluated using Medical Coping Modes Questionnaire (MCMQ).Demographic data,course of the disease,clinical disease activity,and disease phenotype according to Montreal classification were also collected.Univariate analyses were conducted to determine which variables were associated with HRQOL,and those were statistically significant were entered into a multivariate regression model.Results We recruited 214 patients (response rate 92.2％),whose median age was 37.5 (29.0,49.3) years old and median course of UC was 4 (2,9) years.Through univariate analyses,better HRQOL was significantly associated with regular medical visits,lower number of previous relapses and hospitalizations,no steroid use,Montreal E1,lower Mayo scores,clinical remission,less perceived stress and less acceptance strategy use.However,multivariate analyses revealed that perceived stress (OR =1.112,95％ CI 1.058-1.169),acceptance (OR =0.310,95％ CI 0.141-0.685),number of hospitalizations (OR =2.924,95 ％ CI 1.328-6.437) and clinical activity (OR =5.058,95 ％ CI 2.312-11.066) were most strongly related to HRQOL.Conclusions HRQOL of UC patients are not only associated with clinical activity of the disease,but also associated with coping strategy and perceivedstress.Further research needs to focus on whether or not relieving stress and guiding patients to cope with ulcerative colitis would improve HRQOL.

Objective To detect the tissue stiffness of liver lesions by using acoustic radiation force impulse imaging (ARFI) and to evaluate the clinical value on the characteristics of liver lesions.Methods ARFI was perforrned in 91 patients with 103 liver lesions (56 benign,48 malignant).Tbe elastographic images of virtual touch tissue imaging (VTI) and the values of virtual touch tissue quantification (VTQ) were analyzed.The area under the curve and cutoff value for VTQ value were used to assess diagnostic performance.Results On the elastographic images of VTI,79.17 ％ (31/55) malignant liver lesions and 56.36 ％ (38/48) benign liver lesions appeared stiffer compared with the surrounding liver parenchyma.There was statistical difference between malignant and benign liver lesions (x2 =0.627,P ＜ 0.01).The VTQ values of malignant and benign liver lesions were (2.64±0.65) m/s and (1.72±0.39) m/s,respectively,and there was statistical difference between them (t =8.638,P ＜ 0.01).With a cutoff value of 2.10 m/s for VTQ value,the sensitivity and specificity of diagnosis for liver malignancy were 83.3 ％ and 81.8 ％,respectively.Conclusion ARFI can provide information of the tissue stiffuess in live lesions,which is helpful in the differentiation between benign and malignant liver lesions and might become the imaging modality in the future.

Objective To evaluate the effect of obstructive jaundice on recovery from sevoflurane anesthesia in pediatric patients. Methods A total of 80 pediatric patients scheduled for elective surgery were included, 42 pediatric patients with biliary atresia scheduled for Kasai operation served as obstructive jaundice group ( group OJ ) , and 38 pediatric patients scheduled for other operations served as control group ( group C) . Pediatric patients were 1-4 months old and full?term infants, and weighed 3.2-8.0 kg. Anesthesia was maintained with inhalation of 2%-4% sevoflurane during surgery, and pediatric patients inhaled 4% sevoflurane staring from peritoneum closure until the end of surgery. The duration from closing sevoflurane vaporizer to BIS value reaching 60, 70, 80 and 90 was recorded. The duration from stop of sevoflurane inhalation to BIS value returning to 60, 70, 80 and 90 was recorded. The duration from termination of sevoflurane inhalation to the time for tidal volume returning to 6 ml∕kg, to the time for muscle strength recovering to grade Ⅲ, to spontaneous eye opening and to tracheal extubation, and the corresponding BIS values were recorded. BIS value while entering the operating room, BIS value at the end of surgery, and the highest BIS value during recovery from anesthesia were recorded. The occurrence of delayed emergence from anesthesia was recorded. Results Compared with group C, the duration from termination of sevoflurane inhalation to spontaneous eye opening and to tracheal extubation were significantly prolonged, and BIS value at the end of surgery was decreased, and no significant change was found in the other parameters in group OJ. No pediatric patients developed delayed emergence from anesthesia in the two groups. Conclusion When only sevoflurane is used for inhalation anesthesia, although the time for recovery from anesthesia is prolonged, it shows no significant difference clinically in pediatric patients with obstructive jaundice.
