Objective To investigate the prevalence of hypothyroidism during the second trimester and its relationship with thyroid peroxidase antibody (TPOAb). Methods Two thousand one hundred and forty one pregnant women whose gestational age between 14 to 28 weeks,accepted their prenatal care at the outpatient clinic of International Peace Maternity & Child Health Hospital from March 1,2010 to July 31,2010 were enrolled into this study. Serum TPOAb,thyroidstimulating hormone (TSH) and free thyroxine (FT4) of these women were detected. Logistic regression model was used to analyze the risk factors of subclinical hypothyroidism and positive TPOAb,while Spearman rank correlation was used to analyze the relationship between the levels of TSH,FT4 and TPOAb. Results (1) Subclinical hypothyroidism was detected in 13.36％ (286/2141) patients. Isolated maternal hypothyroxinemia occurs in 0.14％ (3/2141) of pregnant women.No overt hypothyroidism patient was detected and 6.26％ (134/2141) of all pregnant women exhibited positive TPOAb(≥50 U/ml).(2) Positive rate of TPOAb in subclinical hypothyroidism group,isolated maternal hypothyroxinemia group and normal thyroid function group was 13.64％ (39/286),0/3 and 5.06％ (86/1701) respectively,and there was difference among the three groups (x2 =30.82,P＜0.01).The positive rate of TPOAb did not relate to fetal gender,maternal age,gestational age,gravidity and parity.(3) TPOAb had positive relationship with TSH level (r=0.12,P＜0.01),while did not relate to FT4 level (r=-0.04,P=0.09). (4) Positive TPOAb (OR 3.18,95％ CI:2.10-4.83,P＜0.01) and gravidity (OR=1.21,95％ CI:1.02-1.43,P=0.030)were risk factors of subclinical hypothyroidism. Conclusions Hypothyroidism is common during the second trimester. It is necessary to screen TPOAb in pregnant women as TPOAb is an independent and important predictor of subclinical hypothyroidism.

Traditional Chinese medicine (TCM) is an important part of modern medicine. Application of modern ana-lytical techniques to identify the authenticity of TCM and evaluate its quality is an important and critical content in the process of the modernization and internationalization of TCM. This paper described the development and charac-teristics of a 1H-NMR-based metabolomics technology, and reviewed its application in the species identification, quality evaluation of Daodi Y aocai (i.e., genuine medicinal materials), processing theory and the best harvest time of TCM. Besides, based on previous work, further discussion was given on technical methods and key question of the 1H-NMR metabolomics method. This paper provided a methodological reference for the species identification and quality evaluation of TCM and other herbal medicines.

On the base of element and metabolism balancing,the mathematic model of the human-like collagen expression phase with recombinant Escherichia coli BL21 was developed and the unknown parameters in the model were estimated with the method of nonlinear optimization.The model was in agreement with the growth kinetics and the metabolic kinetics,and the key calculated parameters of ?h,?p and mx were 1.173 mol?C-mol-1,293.814 mol?C-mol-1 and 17.878 mol?C-mol-1?h-1 respectively.This model could preferably predict the macroscopic reaction rates,and in the synthesis phase of human-like collagen,the specific growth rate should be controlled at 0.04 h-1 with controlling glucose feeding rate to gain the highest specific production rate of human-like collagen.

Objective Alstr(o)m syndrome (AS) is a rare,autosomal recessive inherited disease characterized by various clinical manifestations.The aim of this study was to review the clinical characteristics and laboratory findings of AS.Methods Two cases of AS was reported.Combined with the clinical data of 7 cases of AS which had been reported in China,the clinical characteristics and laboratory findings of AS were reviewed.Results Visual disorder( median onset age:6.0 years ) and dysaudia( median onset age:10.3 years ) were found in 9 patients,short stature and obesity in 8 patients,acanthosis nigricans in 7 patients,diabetes mellitus( median onset age:14.5 years) in 6 patients,and heart disease in 4 patients; hyperuricemia was detected in 6 patients,hepatic dysfunction and hypertriglyceridemia in 5 patients.Conclusions Visual disorder was the first presentation in patients with AS.Deafness,obesity,diabetes,and short stature were common.These findings were helpful in making an early and accurate diagnosis and appropriate treatment.

This paper was to explore the relationship between plasma omentin and obesity and insulin resistance in patients of polycystic ovary syndrome(PCOS).The results showed that there were statistically significant differences in serum omentin levels among control group,PCOS-normal weight group,and PCOS-overweight group [(115.29 ± 33.92),(111.12 ± 34.50),and (42.85 ± 19.39) pg/ml,P＜ 0.05].Omentin were negatively correlated with homeostasis model assessment for insulin resistance(HOMA-IR) and body mass index(BMI).In the multiple stepwise regression analysis,only omentin was negatively correlated with BMI.Omentin may be involved in the development of PCOS by affecting obesity.

Objective:To screen the peptide binding to human bladder carcinoma cells specifically by using phage display technology in vivo.Methods: Nude mice were inoculated with bladder carcinoma cells BIU87 for establishing tumor-bearing mice model.The Ph.D.-C7CTM Peptide Library was injected intravenously via tail vein.Then we screened Phage containing exogenous peptides binding to bladder transitional carcinoma cells specifically.The phage peptide homed to the tumor tissues was obtained after 3 rounds screening in vivo.The phage clones affinity to BIU87 were identified by immunohistochemistry and ELISA.The positive peptide was synthetized by chemical methods after sequencing the positive monoclonal phage DNA.The tumor cell specificity of target peptide was identified by confocal laser scanning microscope and flow cytometry.Results:After 3 rounds screening in vivo,enrichment rate of phage was 4.334×102 times.Immunohistochemistry results showed that the dyeing of the tumor tissue had a rising trend following each round of phage screening,while liver had a lot of non-specific binding phage because the phages were metabolized through liver and kid-ney.The 30 phage clones were identified by ELISA and 10 clones had a strong affinity on BIU87 among 24 positive clones.Three amino acid sequences of positive phage clones were obtained.The highest rate of repeat sequences CSSPIGRHC(8/10) named NYZL1 and the FITC-C6-NYZL1 peptide was synthesized.Our results showed that it could bind to bladder carcinoma cells BIU87 specifically.Conclusion:We obtained the small molecular peptide NYZL1 binding to human bladder carcinoma specifically by means of phage display in vivo,which provide a theoretical basis for bladder carcinoma early diagnosis and targeted therapy.

Objective To investigate the effect of Ginsensode Rgl on the expression of Neurogranin (Ng) and behavioral alteration in cortex and hippocampus of rats with chronic stress model.Methods A total of 36 adult male SD rats were randomly divided into control group (CON),model group (CUS) and treatment group (CUS-G).The chronic stress model was established by chronic unpredictable stress.The Morris water maze was used to study the learning and memory ability.The content of Ng in cortex,hippocampus was detected by RT-PCR and Western blot.Results The water maze test showed that after chronic stress,animal learning and memory ability decreased significantly,while the treatment group rats escape latency was significantly reduced (P＜0.05);after 6 weeks of stress,the cortex and hippocampus Ng mRNA levelschronic stress rats were markedly lower than that of model rats respectively (P＜0.05,P＜0.01,P＜0.05).The cerebral cortex and hippocampus Ng mRNA levels in treatment group were significantly increased compared with that of model group respectively (P＜0.01,P＜ 0.05,P＜0.05);The cerebral cortex and hippocampus Ng levels of chronic stress rat were significantly decreased when compared with that of the model rats respectively (P＜0.05,P＜0.01,P＜0.05),The cerebral cortex and hippocampus Ng content were significantly increased in treatment group compared with the model group respectively (P＜0.01,P＜0.05).Conclusions Chronic stress can change the behaviors of nice in recognization and memory The contents of Ng and the supplement of Ginsensode Rg1 have positive adjustment.

OBJECTIVETo compare the clinical effects between hip anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery and posterior K-L approach combined with quadratus femoris bone flap transplantation for the treatment of femoral neck fracture of Garden III-IV in young and middle-aged patients.

METHODSFrom January 2004 to January 2011,46 patients with femoral neck fractures were treated by two kinds of operation. Among them, 20 cases were treated with anterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery, included 12 males and 8 females with an average age of (32.1 ± 7.3) years old, involved 12 cases of Garden III and 8 cases of Garden IV. The other 26 cases were treated with posterior K-L approach combined with quadratus femoris bone flap transplantation, included 20 males and 6 females with an average age of (37.8 ± 6.9) years old, involved 16 cases of Garden III and 10 cases of Garden IV. The index of hospitalization (hospitalization time, total cost, operative time, intraoperative blood loss, postoperative complications), the quality index of operation (fracture reduction, position of internal fixation, fracture healing time, nonunion and femoral head necrosis) of two groups were observed and compared. Hip joint function were evaluated by Harris score.

RESULTSAll patients were followed up from 28 to 41 months with an average of 36 months. The intraoperative blood loss of group S-P (92.3 ± 10.4) ml was less than that of group K-L (132.4 ± 11.2) ml, there was significant difference between two groups (P < 0.05). The operation time of group S-P (81.4 ± 9.2) min was more than that of group K-L (67.1 ± 4.5) min, the difference was statistically significant (P < 0.05). One case in group S-P and 9 cases in group K-L appeared postoperative complications, there was significant difference between two groups (P < 0.05). The fracture healing time of S-P group (83.5 ± 7.3) d was shorter than that of group K-L (103.2 ± 12.6) d, there was significant difference between two groups (P < 0.05). At 30 months after operation, there were significant difference in Harris scoring between two groups (P < 0.05).

CONCLUSIONAnterior S-P approach combined with iliac bone flap transplantation with deep circumflex iliac artery for treatment of femoral neck fracture of Garden III-IV of young and middle-aged patients, it has characteristics in clear anatomic and easy to operate. As compared with K-L approach, S-P approach can better reserve residual blood supply of femoral neck. While combining with the iliac bone flap transplantation with deep circumflex iliac artery, it could better reconstruct the blood supply of femoral neck to promote fracture healing.
