The effects of solid-state fermentation (SSF) and submerged fermentation (SmF) and the addition of olive oil on the whole-cell lipase production by Rhizopus chinensis CCTCC M201021 were investigated.Compared with SSF, higher biomass, hydrolytic activity and synthetic activity were observed in SmF.By the addition of olive oil, the synthetic activity of whole-cell lipase in both fermentations was enhanced significantly, especially in SmF, while the biomass and the hydrolytic activity were also increased.Hence, olive oil serves as both carbon source and the inducer of lipases in fermentation.It was also found that the synthetic activity of whole-cell lipase was not accordant to the hydrolytic activity during both SmF and SSF, suggesting that isoenzymes with difference in lipase properties may be produced by Rhizopus chinensis.

To explore the relationship between thyroid autoantibodies and thyroid function in school children aged 8-10 years,adults,pregnant women,and lactating women in China,in order to provide reference for the prevention and monitoring of thyroid disease.Healthy 8-10 years old school children (693 cases),adults (698 cases),pregnant women(325 cases),and lactating women(332 cases) from six iodine sufficient areas were enrolled.Serum TSH,FT4,and FT3 were determined by chemiluminescent immunoassay,while antithyroid antibody by radioimmunoassay.The positive rate of thyroid autoantibodies in females was significantly higher than that in the male (5.6％ vs 2.0％ in school children,and 22.8％ vs 3.2％ in adults) ; while positive rate of autoantibodies in pregnant and lactating women (8.9％,8.7％) were significantly lower than that in the other healthy adult women (22.8％).The incidence of abnormal thyroid function in antibody-positive people was higher than that in negative ones in all groups,and abnormal thyroid function showed mainly as subclinical hypothyroidism.In addition,lactating women with negative autoantibodies presented a higher incidence of abnormal thyroid function,mainly as low FT4.The abnormal thyroid function is related with the positive thyroid autoantibodies,indicating that it is essential to follow-up these people with positive antibodies in order to facilitate prevention,early diagnosis,and treatment of thyroid disease.Reference data for thyroid hormones in lactating women should be establisbed as soon as possible.

Objective To study the different selections of delivery mode of pregnant women, and compare their outcomes. Methods Data of 7 509 pregnant women hospitalized in the General Hospital of Tianjin Medical University between January 2013 and December 2014 were retrospectively analyzed. Of them, there were 6 229 cases of primipara and 1 280 cases of multipara. The numbers of vaginal delivery and cesarean delivery were statistical analyzed between primipara and multipara. The cesarean delivery indications of multipara was also studied. The vaginal delivery rates and cesarean delivery rates, and their outcomes were compared between primipara and scar uterus maternal pregnancy. Results The cesarean delivery rate was higher in multipara than that of primipara (69.06%vs. 57.54%,χ2=59.19, P<0.05). Among them, 631 cases were uterine scar pregnancy, 39 cases (6.18%) were vaginal delivery and 592 cases (93.82%) were cesarean delivery. The uterine scar was the main indicator for cesarean delivery in multipara. Compared the outcomes of cesarean delivery, the weight of neonatal body mass was relatively light, the hospital stay was shorter, the amount of 24 h postpartum bleeding and postpartum fever were less in vaginal delivery in primipara and pregnant women with uterine scar ( P<0.05). There were no significant differences in scores of newborn. There were no significant differences in outcomes of vaginal delivery between primipara and pregnant women with uterine scar. Compared outcomes of cesarean delivery between multipara with scar uterus and primipara, there were increased maternal blood loss and postpartum fever in multipara with scar uterus (P<0.05). Conclusion The cesarean delivery is still the mainly mode for multipara. The vaginal delivery is the best mode for pregnant women with scar uterus compared with that of primipara. The vaginal delivery is the safer way of delivery for pregnant women.

BACKGROUND:Nowadays, the internal fixation materials for the clinical treatment of unstable femoral intertrochanteric fractures are broadly divided into two categories:intramedul ary fixation system and
extramedul ary fixation system. However, the effects of the treatments usual y lack of macro evaluation.
OBJECTIVE:To compare the effect of intramedul ary fixation system and extramedul ary internal fixation system in the treatment of unstable femoral intertrochanteric fractures.
METHODS:217 patients with unstable femoral intertrochanteric fracture (Evans typing: Ⅲ type to Ⅴ type and R type) were treated by using intramedul ary fixation system and extramedul ary internal fixation system:18
cases were treated with dynamic condylar screw, 67 cases were treated with dynamic hip screw, 43 cases were treated with reconstruction nail, 72 cases were treated with proximal femoral anti-rotation blade nail, and 17 cases were treated with new generation of antegrade interlocking intramedul ary nail. The operative time, length of
incision, blood loss, time in bed, fracture healing time, complications and Harris hip score were analyzed and compared.
RESULTS AND CONCLUSION:In the aspects of operative time, blood loss, time in bed, complications and
Harris hip score, the intramedul ary fixation system was superior to extramedul ary internal fixation system. But there were significant differences in the aspects of length of incision and fracture healing time between two
methods. The results showed that the treatment of unstable femoral intertrochanteric fractures by using
intramedul ary fixation system was better than the extramedul ary internal fixation system, as the intramedul ary fixation system could effectively shorten the operative time and reduce blood loss. This stable and reliable fixation enables patients to take early postoperative functional exercise, and could significantly shorten the time in bed and reduce the incidence of complications and it is conducive to postoperative hip function recovery.
Therefore, intramedul ary fixation system is an ideal method for the treatment of unstable femoral intertrochanteric fractures.

To explore the value of acoustic radiation force impulse (ARFI) technique in the differential diagnosis of benign and malignant hepatic neoplasms.Retrospective analysis of touch tissue quantification (VTQ) and general ultrasonic examination of interesting region were performed for hepatocellular carcinoma (HCC),hepatic hemangioma,focal nodular hyperplasia (FNH) and controls.Significant differences existed between HCC and hepatic hemangioma,hepatic FNH and controls (all P ＜0.01).No significant difference existed between primary and metastatic HCC (P ＞ 0.05).There was no significant difference between hepatic hemangioma,FNH and controls (all P ＞ 0.05).With a cut-off VTQ value of 1.95 m/s,the sensitivity and accuracy rate in the differentiation of benign and malignant hepatic neoplasms was 90％ and 83％ respectively.The sensitivity and accuracy rate in general ultrasound examination of hepatic neoplasms was 88％ and 70％ respectively.Significant differences existed in accuracy rate between two methods (P ＜ 0.01).It was confirmed that ARFI could reflect the stiffness of liver neoplasm noninvasively.Compared with general ultrasonography,ARFI is better at differentiating benign and malignant hepatic neoplasms.

Objective To evaluate the effect of the needle free injection system (INJEX30) and insulin pen on insulin absorption and glycemic control in diabetic patients.Methods A total of 30 diabetic patients on insulin therapy without obvious complications were enrolled in the study with average BMI of 25.24 kg/m2.A comparison study was carried out in those subjects with the INJEX30 and insulin pen at 1 st day and 5th day.After an overnight fasting of 8-10 h,a standard mixed meal(50 g bread,50 g egg and 250 ml milk) was given to each patient.Blood samples at 0,20,40,60 min of the standard mixed meal were collected to test plasma glucose,serum insulin and C peptide.Results No difference was shown in fasting plasma glucose,serum insulin and C peptide between the patients with the two injection methods.The area under the curve (AUC) of plasma glucose and serum C peptide was significantly lower after the INJEX30 injection than that after insulin pen injection [plasma glucose AUC (542 ± 172) min · mmol · L-1 vs (601 ±199) min· mmol · L-1,P ＜0.01; C peptide AUC (70 ±53) min · μg · L-1 vs (80 ±58) min · μg · L-1,P ＜0.01].The AUC of serum insulin was significantly higher after the INJEX30 injection than that after insulin pen injection [serum insulin AUC(5621 ± 3790) min · mIU · L-1 vs(4285 ± 3376) min · mIU · L-1,P ＜0.01].No difference was found in the AUC of serum insulin between the two injection methods in the patients with BMI below 25.24 kg/m2,while the AUC of serum insulin was significantly higher after the INJEX30 injection than the insulin pen injection in the patients with BMI above 25.24 kg/m2 [serum insulin AUC(6453 ± 4099) min · mIU · L-1 vs (4879 ± 3701) min · mIU · L-1,P ＜0.01].Conclusion The INJEX30 improves the serum insulin level which may lead to a beneficial effect on the glycemic control.Such effect is more obvious in the overweight patients.

Objective To decrease radiation induced toxicities especially mucostis in patients with locally advanced nasopharyngeal carcinoma( NPC ) who underwent concurrent radiochemotherapy, the maximum tolerated dose and dose limited toxicities of capecitabine combination with cisplatin were observed. Methods From Aug 2006 to Oct 2007, 24 patients with intensity modulated radiotherapy(IMRT) and concurrent chemotherapy with capecitabine and cisplatin for nasopharyngeal carcinoma(stages Ⅲ-Ⅳ) were enrolled in this study. There were four dose-level groups of Capecitabine[625-1250 mg/(m2 ·d) , d1-14]and fixed cisplatin dose[20 mg/(m ·d) ,d1-5) ]MRI and CT scan were used for evaluation of tumor shrinkage. Treatment related toxicities were evaluated according to the common toxicity criteria( NCI-CTC Version 3.0). Results The acute side-effects include Grade 3 or Grade 4 mucosal toxicity(lasting for at least 5 d) and Grade 3 or Grade 4 non-mucosal toxicity were evaluated. Group 625 mg/m2 and Group 825 mg/m2 had none, Group 1000 mg/m2 had 6 patients and Group 1250 mg/m2 had 3 patients for mucosal toxicity, which were the main dose-limited toxicity and relevant to the dose of capecitabine apparently( P < 0. 05 ). There was also a trend of increase by the dose level of capecitabine for other toxicities. The median follow-up time for all patients was 28. 5 months. The locoregional recurrence occurred in 2 patients and distant metastasis in 2 patients. Two-year overall survival rate and locoregional control rate were 100% and 91.7%, respectively.Complete response and partialresponse were found on MRI or CT scan in patients of 29. 2% at the end of treatment and 83. 3% after three months, respectively. Conclusions The combination regimen of capecitabine and cisplatin is safe and effective according to the preliminary result. Toxicities related to radiochemotherapy for NPC were significantly associated with the dose level of chemotherapy.

Objective: This study aims to analyze the effects of catastrophic disease insurance (CDI), especially to evaluate the influences of CDI on the discrepancy of benefits between the patients covered by the Employee's Medical Insurance (EMI) and the Resident's Medical Insurance (RMI).Methods: The data used in the study are collected from the health insurance database of Zhuhai City in the years of 2012 and 2014.A descriptive analysis is made to depict the general situation of CDI in the city, and a logistic regression model is used to analyze the factors that affect the probability to get the benefits of CDI.Moreover, a triple difference model is built up to probe into the CDI's effects on the discrepancy of reimbursement ratio between patients covered by EMI and RMI.Results: The benefits of CDI favor the patients with old age, high medical expenditures and chronic diseases.When other factors are controlled, patients covered by EMI have lower probability to get CDI benefits than those covered by RMI.Within the patients with high medical expenditures who have gotten the CDI benefits, those covered by EMI enjoy higher reimbursement ratio than those covered by RMI, but CDI decreases the discrepancy by 3.2%.Conclusions: Since the CDI gives more favor to the vulnerable population and narrows the gap of the benefits between EMI and RMI, the policy improves the equity of health security.

Objective To discuss how to use the core elements of international classification of functioning,disability and health(ICF) as a guide in stroke operation treatment to develop targeted,effective therapy plan and rehabilitation goals,establish individualized treatment of rehabilitation,and to observe the effect of limb movement function in stroke patients. Methods Sixty cases patients with stroke and aged from 40 to 65 years old were selected. The body function and structure of all stroke patients were marked by comprehensive evaluation scores of The National Institutes of Health Stroke Scale ( NIHSS ) and Fugl?Meyer assessment. And then they were randomly divided into two groups,30 cases in each group. The observation group used the Chinese version of brief ICF Core Sets for evaluation, and set individualized treatment according to the results of the assessment;The control group, according to the conventional rehabilitation process, involved in training routine physical therapy. Again 8 weeks after treatment for patients with evaluation,the assessment results was compared with the results of the first assessment. Results Before treatment, the NIHSS, Fugl?Meyer assessment and Chinese version of brief ICF core elements scale scores for the observation group were 7. 95±2. 37,34. 5±4. 0 and 82. 15±17. 96,for the control group were 7. 58±2. 25,34. 8±4. 0 and 81. 55±18. 78. After treatment,the above three rating scale scores, for the observation group were improved to 4. 78 ± 1. 63, 56. 3 ± 4. 2, 60. 45 ±11. 04,for the control group were improved to 5. 13±1. 75,48. 1±3. 8,73. 56±16. 89. The two groups were significantly improved ( observation group:t=4. 94, 15. 51, 18. 59, P<0. 05;control group:t=3. 17, 14. 66, 12. 33,P<0. 05). After treatment,compared with the control group of three rating scale scores(5. 13±1. 75,48. 1
±3. 8 and 73. 56±16. 89),the observation group(4. 78±1. 63,56. 3±4. 2 and 60. 45±11. 04) improved more apparently(t=3. 15,14. 54,15. 45,P<0. 05) . Conclusion Guided by the idea of ICF and scale,with the demand of the patients as the center,to develop personalized physical therapy,can achieve more productive and more targeted rehabilitation goals.
