Objective To investigate the expression and significance of Matriptase and HAI-1 protein in prostate cancer (CaP). Methods Specimens of 46 prostate cancers,20 benign prostate hyperplasias (BPH),10 high-grade intraepithelial neoplasias (PIN),and 10 normal prostates (NP) were used. Expressions of Matriptase and HAI-1 proteins in specimens were detected by SP of immunohistochemistry. The results were analyzed in relation to the clinicopathological data. Results The protein levels of Matriptase in CaP tissues were significantly higher than PIN tissues(Z＝-2.150,P＝0.032),and the expression of matriptase in CaP and PIN was higher than that in BPH and NP (Z＝-3.270,P＝0.001;Z＝-2.817,P＝0.005). No statistically significant difference was observed between BPH and NP group (Z＝-0.895,P＝0.325). A progressive increase in the protein levels of Matriptase was observed with increasing tumor grade (rs＝0.583,P＜0.01) and clinical stages（rs＝0.611,P＜0.01）in CaP specimens. The protein levels of HAI-1 in BPH and NP tissues were significantly higher than CaP and PIN tissues（Z＝-3.277,-3.315,P＜0.01）,the levels of HAI-1 in PIN were higher than CaP (Z＝-2.310,P＝0.020). No statistically significant difference was found between BPH and NP (Z＝-0.872,P＝0.330). A progressive decrease in the protein levels of HAI-1 was observed with increasing tumor grades（rs＝-0.634,P＜0.01） and clinical stages（rs＝-0.521,P＜0.01）. The expressions of Matriptase and HAI-1 in CaP tissues showed negative correlations（rs＝-0.712,-0.560,-0.465,respectively,P＜0.01）. Conclusions The abnormal expressions of Matriptase and HAI-1 proteins may be important events during the progression of CaP in humans. Matriptase and HAI-1 Protein may be used as parameters for assessing the malignancy and prognosis of CaP.

Objective To explore the impacts of preeclampsia and the different extent of proteinuria on maternal and perinatal outcomes.Methods The retrospective analysis was conducted according to the perinatal clinical data of preelacmpsia,pregnancy-induced hypertension in pregnant women and normal pregnant women from the Fifth People's Hospital of Shanghai,excluding twins,diabetic mellitus and patients with chronic kidney disease previously.Patients were divided into three groups on the basis of their conditions:① preeclampsia patients (A group,220 cases); ② patients with gestational hypertension (B group,189 cases); ③ normal pregnant (C group,220 cases).Patients with pre-eclampsia according to the degree of proteinuria were further divided into three subgroups:A1:patients with mild proteinuria (n =109); A2:patients with moderate proteinuria (n =72); A3:patients with severe proteinuria (n =39).Results Compared with the other two groups,the patients in A group had higher blood pressure,serum creatinine,uric acid,cesarean section rate,perinatal prematurity,stillbirth,fetal distress and neonatal asphyxia in preeclampsia group.However,the serum albumin level,eGFR,neonatal birth weight,length and Apgar scores were lower in A group compared with B and C group (P ＜ 0.05).In three subgroups,serum creatinine level,uric acid level,cesarean section rate,perinatal prematurity and fetal distress were significantly increased in A3 group compared with A1 group,while the serum albumin level,eGFR,gestational age and neonatal birth weight were obviously lower in A3 group than in A1 group (P ＜ 0.05).In patients with preeclampsia,24 h urinary protein was negatively related with the levels of serum albumin and eGFR (P ＜ 0.05),and positivly related with the blood pressure,serum creatinine and caesarean production rate (P ＜ 0.05).Large amounts of proteinuria was a risk factor of adverse outcome for pregnant patients with preeclampsia (OR =2.899,P ＜ 0.05).Conclusions Preeclampsia patients with large amount of proteinuria have poor maternal and perinatal outcomes.Massive proteinuria is a risk factor of adverse outcome for patients with pre-eclampsia.

AIM To observe the endometrium receptivity of polycystic ovary syndrome patients and research advance of expression of HOXA10 in endometrium.METHODS Eighty PCOS patients were divided into treatment group and control group,40 persons in each group randomly.The control group was treated with clomiphene (CC) + human menopausal gonadotropin (HMG) + human chorionic gonadotropin (HCG),and the treatment group was treated with CC + HMG + HCG + Yin-Nourishing Yang-Supplementing.After 3 periods,take a record for below:endometrial thickness (Em) in the middle,advanced stage and mid-secretory phase of hyperplasia endometrii,the levels of spiral artery PI/RI in midluteum endometrium,the levels in serum of E2 and P in midluteum endometrium,the expression of HOXA10 mRNA from both groups,clinical pregnancy rate and abortion rate for each group.RESULTS Compared with the control group,endometrial thickness in the treatment group was increased and there is statistical difference in the middle and late follicle phases (P ＜ 0.05),but there was no statistical difference in midluteum endometrium (P ＞ 0.05);the level of E2 and P in the treatment group were raised (P ＜0.05) with statistical significance;PI and RI were obviously contracted (P ＜ 0.01).Expression of HOXA10 mRNA was increased (P ＜ 0.01).Compared with the control group,the treatment group had a significant difference in pregnancy rate (P ＜ 0.05).The abortion rate was lower,but there was no statistical significance (P ＞ 0.05).CONCLUSION Yin-Nourishing Yang-Supplementing Treatment can obtain higher pregnancy rate and lower abortion rate of PCOS patients and the mechanism might be associated with raising the expression of HOXA10 mRNA and reducing spiral artery PI/RI,also improving the function of corpus luteum treatment,then to improve the receptivity of endometrium.Yin-Nourishing Yang-Supplementing Treatment is well worth popularizing in further clinical application.

Background The different incisions in phacoemulsification,including the length,location and shape etc.,can cause surgery-induced astigmatism ( SIA ).But the SIA caused by 2.2 mm,3.0 mm corneal limbal incision after phacoemulsification,especially the change of posterior corneal surface astigmatism is still rarely reported. Objective This study was to investigate the anterior,posterior and total corneal SIA and compare their differences between phacoemulsification and foldable intraocular lens (IOL) implantation with 2.2 mm and 3.0 mm corneal limbal incisions. Methods Seventy-one eyes of 47 cases were randomly divided into two groups with matched age,visual acuity and astigmatism degree.Phacoemulsification and IOL implantation with 2.2 mm incision at the steepest corneal meridian was performed on the patients of 2.2 mm incision group,and the same surgery was adopted with 3.0 mm incision as 3.0 mm incision group.Corneal curvature radius and central corneal thickness were measured by Pentacam at 1 day before surgery and 1 week,1 month and 3 months after surgery respectively.The anterior and posterior corneal surface SIAs were calculated according to the flat axis and steep axis of corneal curvature and the air and the cornea refractive index.Based on the anterior and posterior surface SIAs,the total corneal SIA was then calculated using the vector analysis method.Jaffe/Clayman vector method was used to calculate the anterior and posterior and total corneal SIAs in the different time points,and the differences were compared between the two groups.Oral informed consent was obtained from each subject prior to the trial. Results The mean anterior and posterior surface corneal SIAs appeared to be lower in 2.2 mm incision group compared with 3.0 mm incision group at postoperative 1 day,1 week,1 month and 3 months but were not significantly different among groups at various time points ( anterior SIA:P =0.290 ; posterior SIA:P =0.740 ; total SIA:0.434 ).The mean anterior corneal surface SIAs were significantly lower at the postoperative 3 months than those at postoperative 1 day,1 week in both groups(2.2 mm incision group:P=0.020,0.036;3.0 mm incision group:P=0.006,0.023 ).The posterior corneal surface SIAs were (0.70±0.43 ) D and (0.75 ±0.54 ) D at 1 day in 2.2 mm incision group and 3.0 mm inscision group,respectively,and significantly decreased posterior corneal surface SIAs were found in postoperative 1 week,1 month and 3 months compared with 1 day in both groups ( 2.2 mm incision group:all P =0.001 ; 3.0 mm incision group:P=0.028,0.044,0.032).The total corneal surface SIA showed significant differences between 1 day and 1 week,1 month,3 months after surgery ( 2.2 mm incision group:P =0.015,0.002,0.002 ; 3.0 mm incision group:P =0.049,0.007,0.016 ). Conclusions There are no significant differences in the anterior,posterior and total corneal surface SIAs between 2.2 mm and 3.0 mm incisions after phacoemulsification with IOL implantation.The SIA is gradually reduced with the prolongation of postoperative time.

Objective To investigate the epidemiological characteristics of incipient neonatal hyperbilirubinemia. Methods The clinical data of admitted neonates with hyperbilirubinemia were retrospectively analyzed from June 2012 to May 2013. Results Two hundred and eight-four neonates with hyperbilirubinemia were enrolled and the ratio of male:female was 1.51:1. For the causes of hyperbilirubinemia, the incidences of ABO hemolytic and sepsis were higher in term infants than those in preterm infants, and the incidences of pneumonia, necrotizing enterocolitis and intracranial hemorrhage were higher in preterm infants than those in term infants (P<0.05). Compared with the preterm infants, the term infants had jaundice appearance and peak at earlier time, shorter duration of jaundice, faster decline rate of jaundice, higher levels of albumin and indirect bilirubin at the peak of jaundice (P<0.01). In the term infants, the time of jaundice appearance and peak were earlier in hemolytic group than those in non-hemolytic group (P<0.05). In preterm infants, the peak of transcutaneous bilirubin was higher in hemolytic group than that in non-hemolytic group (P<0.05). Six cases with bilirubin encephalopathy had abnormalities cranial MRI imaging, and the MRI was not entirely consistent with the peak level of bilirubin. Conclusions There are clinical differences between hemolytic and non-hemolytic hyperbilirubinemia in both term and preterm infants.

Objective: To observe the effects of needles with different diameters on the gastrointestinal function in mice. Methods: Eighteen Kunming mice were randomly divided into group of 0.25 mm needle, group of 0.35 mm needle, and control group. The acupoint of Zusanli (ST 36) was needled once a day for 5 days. The effects of needles with different diameters were observed by measuring the distance of the carbon moved in the intestine. Results: The distance of the carbon moved in the intestine was longer in the acupuncture group than in the control group (P<0.05), and it was longer in the group of 0.35 mm needle than in the group of 0.30 mm needle, there was no significant difference (P>0.05). Conclusion: Acupuncture treatment can enhance the peristalsis function of stomach and intestine in mice. The diameter of needle has no effect on the gastrointestinal function.

Aim To establish experimental colitis model in Balb/c mice by Trinitrobenzene Sulfonic Acid (TNBS) enema. Methods Several doses of TNBS instilled into mice colon induced experimental colitis, then mortality rates of mice were observed. Severity of colitis was evaluated by the Disease Activity Index (DAI),Morphologic and Histologic analysis and Myeloperoxidase (MPO) analysis. We also observed the T cell proliferation of spleen. Results It showed that the mice mortality rate was increased when the mice were given the higher dose of TNBS. Most survived mice showed chronic inflammation in reduction colon. Histological examinations of the colon showed multiple erosive lesions and inflammatory cell infiltration composed of macrophages, lymphocytes, neutrophils in lamina propria and beyond mucosal layer. Some colon showed crypt distortion or reduction and high vascular density. Conclusion A TNBS dose of 1.5mg for each mouse was chosen for an appropriate experimental dose since the group showed less mortality rate and appropriate experimental colitis.

ObjectiveTo observe the growth of BT-325 human glioma cells after interfering volume-regulated chloride channel ClC-2 gene.MethodsTwo expression recombinant vectors of ClC-2 gene were designed and constructed. The primary plasmid, pSUPER.puro-shRNA, and the two recombinant plasmids, pSUPER.puro-shRNA-ClC-21 and pSUPER.puro-shRNA-ClC-22, were transfected into BT-325 cells by LipofectamineTM2000 (Groups: control, PP1 and PP2, respectively). The mRNA expression of ClC-2 gene was detected with reverse transcription polymerasse chain reaction (RT-PCR), the cellular survival was determined with MTT assay, and the cell cycle was measured with flow cytometry (FCM). ResultsClC-2 mRNA expression and the growth of the cells in PP1 and PP2 groups were significantly lower than that of control group. The cell cycle progression was blocked in G1 phase (PP1 and PP2 vs control,P<0.01). ConclusionThe growth of BT-325 human glioma cells is prevented by knockdown of ClC-2 gene expression, which may be one of the novel targets to inhibit growth of human malignant glioma cells.

OBJECTIVEThis study simulated clinical implant surgery using squeeze technique by establishing a rational animal model. To measure the morphologic parameters in order to observe the agglutination of the cancellous bone after being compressed. The study wanted to get some favourable support of implant squeeze technique in bone healing and obtaining primary stabilities of implants, so as to provide some reasonable and valid guidance in the application and improvement of implant squeeze technique.

METHODSThe cancellous bone in condyles of femur of dog had been chosen as the experimental position, prepared the implant holes using squeeze technique according to different compressing extent (0, 0.6, 1.2, 2.0 mm), and then inserted the corresponding implants into them. After different healing periods (1, 2, 4, 12 weeks), the mongrel dogs were sacrificed and the hard tissue slices were made and then the morphologic parameters were measured.

RESULTSThe morphologic parameter of the bone tissue shows that after being compressed, the trabecular bone thickness was almost constant, while the trabecular bone number increased, and the trabecular bone spacing decreased, obviously in the 1-week and 2-week groups. The differences went down gradually along with the extend of healing time.

CONCLUSIONThe clinical implant surgery using squeeze technique can improve peri-implant bone density so it is good for obtaining primary stabilities of implants.
