Objective To summarize the characteristics of fetal hand deformity in prenatal two-and three-dimensional u1trasonography. To analyze the causes of missed diagnosis of prenatal u1trasonography in detecting fetal hand deformity. Methods Systematic continuous sequence approach was performed with two-and three-dimensional u1trasonography in 11 854 cases to detect the fetal hand development, deformity and accompanied malformations. Prenatal sonographic features of fetal hand deformities (59 cases) were correlated with the morphology and X-ray characteristics of the delivered fetuses. Results Fifty-nine cases of fetal hand deformity were diagnosed out of 11 854 fetuses by prenatal u1trasonography:44 cases of abnormal wrist posture,1 case of full-ifnger absence, 2 cases of metacarpal and phalanx absence, 3 cases of clinodactyly, 2 cases of forearm and hand absence, 1 case of syndacty, 1 case of polydacty, 5 cases of lethal bone dysplasia. The detection rate was 0.50%(59/11 854). Eight cases were missed:3 cases of partial ifnger absence, 2 cases of clinodactyly, 1 case of syndacty, and 2 cases of polydacty. The rate of missed diagnosis is 11.90%(8/67). Abnormal wrist posture showed a hook-shaped hand in the wrist. Full-finger absence showed that one or multiple ifngers were absent. Metacarpal and phalanx absence showed no fetal hands. Clinodactyly showed that four ifngers were not in the same plane. Forearm and hand missing showed that ulna, metacarpal and phalangeal were absent. Syndacty showed a beak-like hand. Multi-ifnger indicated six ifngers in one hand. Lethal bone dysplasia showed very short limbs. Conclusions Prenatal u1trasonography played an important role in detecting and diagnosing severe type of fetal hand deformity. The detection rate of fetal hand deformities can be greatly improved by appropriate use of the scan-time, fetal position, systematic continuous sequence approach and real three-dimensional u1trasonography.

Objective Modified upper abdominal cluster transplantation (MCT), which was inspired by the classical cluster transplant technique, has been proven more effective and feasible in the treatment of patients with end stage liver diseases associated with insulin-dependent diabetes mellitus (DM) than orthotopic liver transplantation (OLT) alone. In this study, we summarized our experience with MCT in 5 consecutive patients suffering from end stage liver diseases associated with insulin-dependent type 2 DM in our single center.Methods Five patients with hepatitis B-related chronic liver cirrhosis and insulin dependent type 2 DM received MCT in our single center. The biliary and exocrine pancreatic drainage reconstructions were achieved by a Roux-en-Y duodenojejunostomy or a side-to-side duodenojejunostomy. A quadruple immunosuppressive regimen based on tacrolimus including Basiliximab induction, mycophenolate mofetil (MMF) and steroids was used in the early stage post-transplant, and then converted to tacrolimus monotherapy.Results All of the patients experienced an uneventful post-operative recovery. They were rendered independent from insulin therapy shortly after transplantation. The fasting glucose and glycosylated hemoglobin levels were within normal range. In addition, the fasting C-peptide value was increased from much lower than the normal range pre-transplant to within normal range post-transplant and maintained stable since then. However, the third patient suffered from graft verse host disease (GVHD) 20 days post-operatively and died from severe infection on the post-operative 47 days. The other 4 patients had returned to work and a normal lifestyle over 22, 15, 5 and 4 months of follow-up.Conclusion MCT is an effective method in treating patients suffering from end stage liver diseases combined with insulin-dependent type 2 DM. Whether a cluster graft would increase the risk of GVHD needs further investigation.

OBJECTIVETo evaluate the feasibility of cone beam computed tomography (CBCT) for the evaluation of trabecular bone structure in mandibular condyle and to investigate the distribution of the trabecular bone structure within mandibular condyle.

METHODSEighty condyles from 40 healthy young volunteers (aged 20-32) were scanned by CBCT. A coronoid image was acquired of each condyle and divided into 8 regions where regions of interest were specified. After CBCT images were binarized, four morphological parameters including bone volume fraction, trabecular thickness, trabecular number and trabecular separation were computed.

RESULTSAll parameters were significantly different between the superior zone and middle/inferior zone of the condyle (P < 0.05). Superior zone showed the largest bone volume fraction (52.2%), the highest trabecular number (1.33 mm(-1)), the thinnest trabecular thickness (393.48 microm), and the smallest trabecular separation (361.59 microm). Inferior zone showed the smallest bone volume fraction (49.64%). These results were not significantly different between bilateral sides of the condyles (P > 0.05).

CONCLUSIONSTrabecular bone structure was inhomogeneous within the condyle, but symmetrical between bilateral sides of the condyles. CBCT combined with image processing is a feasible tool in evaluating trabecular bone structure of human mandibular condyle.

ObjectiveSLC2A9 is a novel identified urate transporter that affects serum uric acid levels. The present study is aimed to investigate rs7442295 polymorphism in intron 6 of SLC2A9 in a population of Chinese male gout or hypemricaemia subjects. MethodsA total of 268 gout patients and 288 healthy male volunteers were included. Blood pressure, body mass index(BMI), serum uric acid, glucose, lipid,urea and creatine were detected. DNA was purified from peripheral blood and the rs7442295 polymorphism was evaluated using high resolution melting ( HRM ) analysis and direct sequencing. Data were analyzed with t test or chi-square test. Results A/A and A/G genotypes were unambiguously distinguished with HRM technology. The occurrence of the homozygous type (G/G) was completely absent among the study population.The prevalence of the A/A and A/G genotype was 96.2％ and 3.8％ respectively. However, no significant differences of genotype frequencies were found in gout patients and normal subjects(x2=0.003, P=0.82; x2=0.003, P=1.00). But the serum uric acid levels in individuals with the A/G genotype[(293±100) μmol/L]were significantly lower than those with the A/A genotype[(392±133) μmol/L](t=2.426, P＜0.01 ). The A/G genotype frequency was significantly higher in the low-uric acid group than in the high uric-acid group (x2=6.279, P=0.01 ). Genotyping based on HRM was fully concordant with sequencing. Conclusion The polymorphism rs7442295 in SLC2A9 may be a genetic marker to assess risk of hyperuricemia among Chinese male Hart population. HRM is a simple, fast, reliable and close-tube technology for genotyping.

Objective To investigate the effect of electroacupuncture on the expressions of endoplasmic reticulum stress-related proteins in the substantia nigra in a rat model of rotenone-induced Parkinson disease.Methods One hundred and twenty healthy male SD rats were randomized to normal, sham operation, model, electroacupuncture pretreatment, and 7-day, 14-day, 21-day and 28-day electroacupuncture treatment groups, 15 rats each. A model of Parkinson disease was made by subcutaneous injection of rotenone in the nape. The sham operation group received an injection of equal volume of sunflower oil emulsion. The normal, sham operation and model groups were not treated. The electroacupuncture treatment group received electroacupuncture at points Fengfu (GV 16)and Taichong (LR 3) after model making. The electroacupuncture pretreatment group received model making after 7 days of electroacupuncture treatment. TH and α-syn positive cells expressions in rat substantia nigra were determined by immunohistochemical method. BiP and CHOP expressions in rat substantia nigra were examined by Western blotting. Results The model group rats had obvious syndrome characteristic of PD and rat behavior score decreased significantly after electroacupuncture intervention (P<0.01).α-syn positive cells expression and BiP and CHOP expressions in rat substantia nigra increased significantly and TH positive cells expression in rat substantia nigra decreased significantly in the model group compare with the normal and sham operation groups (P<0.01).α-syn positive cells expression and BiP and CHOP expressions in rat substantia nigra decreased significantly and TH positive cells expression in rat substantia nigra increased significantly in every electroacupuncture treatment group compare with the model group (P<0.01).Conclusions The mechanism of electroacupuncture prevention and treatment of Parkinson disease may be related to its significant inhibition of the expressions of endoplasmic reticulum stress-related proteins and protection of dopaminergic neurons.

Objective To study the effect of metformin on glucolipid metabolic disorders and liver lipid deposition caused by clozapine in rats.Methods From 1 d to 4 d,Clozapine 5 mg·kg -1 ·d -1 was gavaged,and the dose increased to 25 mg·kg -1 ·d -1 from the 5th day.Metformin 100 mg·kg -1 ·d -1 or 400 mg·kg -1 ·d -1 or simvastatin 1 mg· kg -1 ·d -1 was gavaged from the 15th day.The total period of dosing was 8 weeks.Body mass,fasting blood sugar (FBS) and postprandial 2 hours blood glucose (2hPBG)were measured at baseline,3 d,1 week,2 weeks,4 weeks,6 weeks and 8 weeks.At the end of the 8th week,serum cholesterol (TC),triglyceride (TG),low density lipoprotein (LDL -C), high density lipoprotein (HDL -C),fructosamine (FA)and insulin (IRS)were measured and liver HE staining was done.Results There were no significant differences of the measured indexes between control group and metformin group at the all test points.By the end of the 6th and 8th week,compared with control group,the body mass,FBS,2hPBG,IRS, FA,TC,TG and LDL -C were significantly increased in clozapine group (P <0.05 ),while HDL -C decreased in clozapine group (P <0.05).Compared with clozapine group,body mass,FBS,2hPBG,IRS,FA,TC,TG and LDL -C were significantly decreased by metformin or simvastatin administration (P <0.05),while HDL -C increased(P <0.05).Rat liver cells in clozapine group were not neat around the small blood vessels;there were more white fat cells and hepatocellular lipid calm far away from the blood vessels.However,in other groups,there were moderate white fat cells, and there were not much hepatocellular lipid calm far away from the blood vessels.Conclusion Metformin could effectively prevent and treat weight gain,glucolipid metabolic disorder and liver lipid deposition caused by clozapine.

OBJECTIVETo study the effect of Tadalafil combined with behavior therapy in helping obtain semen from infertile men in whom masturbation has failed.

METHODSSixty male infertile patients from whom masturbation had failed to obtain semen were equally assigned to receive Tadalafil combined with behavior therapy (combination group) or Tadalafil only (control group). All the patients took Tadalafil 20 mg orally the night before the day of semen collection by masturbation. Before this procedure, the patients of the combination group practiced masturbation 16 - 24 times at home.

RESULTSThe average ages of the patients were (37.0 +/- 5.1) yr and (37.5 +/- 5.2) yr and their IIEF-5 scores were 16.50 +/- 1.25 and 16.90 +/- 1.09 in the combination and the control group, respectively, neither with statistically significant difference between the two groups. Semen was successfully obtained from 9 patients (30.0%) of the combination group and 1 patient (3.33%) of the control group, with statistically significant difference between the two groups (chi2 = 7.680, P < 0.01).

CONCLUSIONBy training the patients and establishing a conditioned response to masturbation, Tadalafil combined with behavior therapy can significantly increase the success rate of semen collection from the male infertile patients in whom masturbation fails.

BACKGROUNDThe accurate and comprehensive assessment of glycemic control in patients with diabetes is important for optimizing glycemic management and for formulating personalized diabetic treatment schemes. This study aimed to analyze the correlation between 1,5-anhydroglucitol (1,5-AG) and glycemic excursions in type 2 diabetic patients.

METHODSSeventy-one outpatients with type 2 diabetes mellitus were randomly recruited from Chinese People's Liberation Army General Hospital. Using a continuous glucose monitoring system (CGMS), these patients' blood glucose levels were monitored for three consecutive days to obtain mean blood glucose (MBG) data. Intraday glycemic excursions were evaluated using the mean amplitude of glycemic excursions (MAGE), the largest amplitude of glycemic excursions (LAGE), standard deviation of blood glucose (SDBG) and the M-value. Interday glycemic excursion was assessed by absolute mean of daily difference (MODD). Postprandial glycemic fluctuations were evaluated using postprandial glucose excursions (PPGE) and postprandial incremental area under the curve (iAUC). Fasting venous blood samples were collected to measure serum 1,5-AG, whole-blood hemoglobin A1c (HbA1c) and serum glycated albumin (GA). Clinical markers of glycemia and parameters of glycemic excursions from CGMS were analyzed using the Pearson correlation coefficient and multivariate stepwise regression.

RESULTSPearson correlation analysis revealed that 1,5-AG was significantly correlated with MAGE, SDBG, M-value, LAGE, PPGE and iAUC (r values were -0.509, -0.430, -0.530, -0.462, -0.416 and -0.435, respectively, P < 0.01), especially in moderately and well-controlled patients, based on defined HbA1c levels. Multivariate stepwise regression analysis revealed a negative correlation between 1,5-AG and the above parameters, but not HbA1c and GA. Finally, HbA1c and GA were positively correlated with MBG and fasting blood glucose (FBG).

CONCLUSIONS1,5-AG was much better than HbA1c and GA as a marker of glycemic excursions in type 2 diabetic patients. Based on these results 1,5-AG is the best metric for assessing postprandial glucose levels in moderately and well-controlled patients, while HbA1c and GA were superior to 1,5-AG for monitoring MBG and FBG.
