Objective To study the relationship between the serum selenium(Se) concentra- tion and glutathione peroxidase(GSH-PX) levels in red blood cell in patients with pregnancy induced hypertension(PIH).Methods The serum Se concentration was measured by atomic absorbability assay and the GSH-PX levels were measured by cellular chemiluminescence assay.49 cases of PIH and 34 normal pregnant women were measured for serum Se concentration and GSH-PX levels in red blood cell from April,1994 to December,1994.Results The serum Se concentration and GSH-PX levels in red blood cell is different betwen PIH and control group.Compared serum Se concentration and GSH-PX levels were significant lower in the PIH patients than in the control subjects (P

The mechanisms of general anesthesia, which was introduced about 170 years ago, remain poorly under- stood. Even less well understood are the effects of general anesthesia on the human body. Recently we identified 18 G-protein coupled receptor (GPCR) genes of Daphnia pulex, an invertebrate model organism. Phylogenetic analysis identified these genes to be the homologs of the human γ-aminobutyric acid, type B (GABAB) receptor, metabotropic glutamate receptors (mGluR), adrenergic receptor, serotonin (5-HT) receptor, dopamine receptor and muscarinic acetylcholine receptor (mAChR). Using reverse transcription and quantitative PCR techniques, we systematically measured the effects of propofol, etomidate and ethanol on these 18 GPCR mRNA expressions in Daphnia pulex.

Objective To evaluate the value of high frequency ultrasound in sciatic nerve of rat with diabetic neuropathy.Methods Fifty male Sprague-Dawley rats were divided into 4 groups:Diabetic animals were induced by intravenous injection of streptozotocin after high fat feed for 1 month,after which rats were grouped as 3-month (n =12) and 5-month (n =20) diabetes.Control group were received the streptozotocin vehicle and were classified as 3-month group (n =8) and 5-month group (n =10).Ultrasounic study of cross sectional area (CSA) and pathologic study including number and area of nerve fiber were performed at 3 and 5 months according to the disigned.Results The CSA,number and area of nerve fiber in 5 month diabetes were significantly reduced than 5-month control group (t =5.121,P ＜ 0.05; t =7.113,P ＜0.05; t =6.328,P ＜0.05).The CSA were statistically with the number and area of nerve fiber in 5 month diabetic group (r =0.732,P ＜0.05 ; r =0.715,P ＜0.05).However,the CSA had no significant correlation with the number and area of nerve fiber between 3-month diabetes and control group (P ＞0.05).Conclusions The CSA of sciatic nerve can evaluate the diabetic neuropathy of rat,which might be regarded as a potential index in diagnose of diabetic neuropathy.

Objective To observe the influence of Qingwen Baidu decoction (QBD) on serum procalcitonin (PCT) and C-reactive protein (CRP) levels in septic rats and study the mechanism of heat-clearing and detoxifying method for treatment of sepsis. Methods Fifty male Sprague-Dawley (SD) rats were randomly divided into control group (n=5), model group (n=25), and heat-clearing and detoxifying experimental group (experimental group, n=20). The septic model was reproduced by intra-peritoneal injection of lipopolysaccharide (LPS, 5 mg/kg). In control group, an equal volume of normal saline was given. After modeling for 2 hours, the heat-clearing and detoxifying experimental group received QBD the first time (composition of the decoction: Gypsum Fibrosum Recens 30 g, Rehmanniae Radix 10 g, Bubali Cornu 15 g, Coptidis Rhizoma 4 g, Gardeniae Fructus 5 g, Platycodonis Radix 5 g, Scutellariae Radix 5 g, Anemarrhenae Rhizoma 5 g, Paeoniae Radix Rubra 5 g, Scrophulariae Radix 5 g, Forsythiae Fructus 5 g, Glycyrrhizae Radix 5 g, Moutan Cortex 5 g, Lophatheri Herba 5 g) by gavage (0.01 mL/g); the rest administration time was 08:00 to 09:00, once a day. The rats in model group were given an equal volume of warm water by gavage. At different time points after modeling, the blood of 5 rats in control group, model group, and experimental group was collected from the abdominal aorta. The serum PCT and CRP levels were tested by the enzyme linked immunosorbent assay (ELISA), and the pathological changes in lung and intestinal tissue were observed under a light microscope. Results Compared with the control group, the PCT level of the model group after modeling for 2 hours was significantly increased (ng/L:332.32±22.85 vs. 70.46±3.18, P<0.01), this situation continued until 72 hours after modeling. CRP level in the comparison between the control and model groups did not have statistical significant difference at 2, 8, and 48 hours after modeling (all P > 0.05). The level of CRP in model group was lower than that of control group at 24 hours and 72 hours after modeling (μg/L:281.34±32.81, 237.84±41.42 vs. 350.09±56.67, P<0.05 and P<0.01). There were no statistically significant differences in PCT levels between model group and experimental group after modeling for 8 hours and 24 hours (both P > 0.05). The PCT level of experimental group was significantly lower than that of model group beginning from 48 hours after modeling (ng/L: 321.57±28.00 vs. 358.12±10.14, P < 0.05), and this situation continued until 72 hours after modeling (ng/L: 269.50±49.10 vs. 347.69±26.90, P <0.05). The CRP level of experimental group was significantly lower than that of model group beginning from 8 hours after modeling (μg/L:232.73±13.29 vs. 335.35±53.78, P<0.05), this statistical significant difference between the two groups persisted until 72 hours after modeling (μg/L:177.31±6.70 vs. 237.84±41.42, P<0.05). Compared to those in the model group, the lung tissue inflammatory cell infiltration, the intestinal mucosal inflammation and interstitial edema were milder in the experimental group. Conclusion Heat-clearing and detoxifying therapy can effectively reduce the serum PCT and CRP levels of septic rats induced by LPS, and it can alleviate the infiltration of inflammatory cells in lung tissues so as to play a role in protection of tissue organ.

This study examined the effects of Bangdeyun on the expressions of nuclear factor-kappaB (NF-kappaB), interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) in the endometrium of mice with embryo implantation dysfunction (EID) during the implantation time (namely on pregnancy day 5, 6, 7 and 8) and explored the local immune regulatory effects of Bangdeyun. The gestational mice were randomly divided into normal group, model group and Bangdeyun-treated group. EID models of mice were established by using indomethacin. The endometrial expression of NF-kappaB was detected by immunohistochemistry and Western blotting. IFN-gamma and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). The results showed that in the normal group, NF-kappaB and IFN-gamma were weakly expressed and IL-10 was strongly expressed in the endometrium during the whole implantation period. In the model group, the expressions of NF-kappaB and IFN-gamma were increased on pregnancy day 5, 6 and 7, and IL-10 expression decreased during the whole implantation time when compared with those in the normal group (P<0.01 for all). In the Bangdeyun-treated group, little amount of NF-kappaB and IFN-gamma was expressed and IL-10 expression was strong, much the way they were expressed in the normal group (P>0.05). The expressions of NF-kappaB and IFN-gamma were much lower in the Bangdeyun-treated group than those in the model group on pregnancy day 5, 6 and 7 (P<0.01 for all), while the expression of IL-10 was much higher than in the model group during the whole implantation time (P<0.01). It was suggested Bangderun may favor a shift from Th1- to Th2-type immune response, therefore inhibiting the maternal immune rejection, inducing the immune tolerance and improving the fetal implantation.

Objective To investigate the application of fusion imaging in the initial prostate biopsy.Methods Retrospective analysis was made on 40 patients who underwent initial ultrasound-guided prostate biopsy in Shanghai Jiao Tong University Affiliated 6th People's Hospital from August 2014 to May 2015.All patients underwent preoperative magnetic resonance imaging (MRI) scans one week prior to surgery and the results showed that all patients had suspicious positive prostate cancer lesions,while there were no positive findings in the same area in sonography.All patients with prostate cancer have been confirmed by pathologic examination.Image fusion technology was used to guide the biopsy of lesions which were suspected as prostate cancer by MRI,and then the prostate underwent systematic biopsy by 10 needles under the guide of ultrasound.R× C Chi-square test was used to compare the positive ratio among imaging fusion biopsy,systematic biopsy and combined method in the diagnosis of prostate cancer.Fourfold table Chi-square test was used to compare to undetected rate between fusion imaging biopsy and systematic biopsy in the diagnosis of prostate cancer.The differences of detection rate in the Gleason score more than 7 points of prostate cancer between fusion imaging biopsy and systematic biopsy was compared by Fisher exact test.Results In this group of 40 patients with prostate biopsy,14 cases (35.0％) were diagnosed prostate cancer by systematic biopsy,19 cases (47.5％) were diagnosed prostate cancer by image fusion biopsy,and 22 cases (55.0％) were diagnosed prostate cancer by systematic biopsy combined with image fusion.The difference of diagnostic positive rate among combined method of biopsy,image fusion biopsy and systematic biopsy had not statistically significant (P ＞ 0.05).Three cases (13.6％,3/22) of prostate cancer patients were missed in image fusion method group,and 8 cases (36.4％,8/22) of prostate cancer patients have not been diagnosed by systematic biopsy,which indicated the umdetected rate of systematic biopsy is higher than that of image fusion biopsy in prostate cancer diagnosis,and there was a statistical difference between the two groups (x2=8.338,P=0.005).Among 19 cases of prostate cancer patients who were diagnosed by image fusion biopsy method,Gleason score were greater than 7 points in 15 cases (78.9％,15/22).Among 14 cases of prostate cancer patients who were diagnosed by systematic biopsy method,Gleason score were greater than 7 points in 6 cases (42.9％,6/14).The positive rate of Gleason score ≥ 7 points in fusion imaging biopsy was higher than that of systematic biopsy,which had a statistical difference (Fisher exact probability method,P=0.039).Conclusion Image fusion method can be used to reduce the tndetected rate of prostate cancer and improve the detection rate of the high-grade prostate cancer.

This study was aimed to investigate effect of aconite alkaloids on proliferation and apoptosis of hu-man gastric cancer cell line SGC-7901 . Effects of different concentrations of aconite alkaloids on proliferation of human gastric cancer cell line SGC-7901 were investigated with MTT assay; induced apoptosis and cell cy-cle blocking were detected with flow cytometer ( FCM ) . The results showed that the IC50 of aconite alkaloids on human gastric cancer cell line SGC-7901 was 0 . 2318 ± 0 . 0022 , 0 . 1601 ± 0 . 0227 , 0 . 1031 ± 0 . 0231 mg/ml at 24 h , 48 h and 72 h , respectively , compared to the control group with significant difference ( P <0.01). When the aconite alkaloids concentration was 0.8 mg/ml, it appeared with obvious apoptosis. The apop-tosis rate was ( 59 . 38 ± 5 . 05 )%. The FCM detection showed that compared with control group , the percentage of S-phase cells increased in the treatment group . And a typical sub-diploid peak appeared before G0 / G1 phase . It was concluded that aconite alkaloids can inhibit the proliferation of human gastric cancer cell line SGC-7901 in vitro, induce the apoptosis of cells and make SGC-7901 cells remain in S phase.

Objective To analyze the nursing interventions of two kinds of percutaneous nephrolithotomy (PCNL),so that we can provide personalized service for patients with PCNL and improved quality of nursing. Methods 140 cases of patients undergoing PCNL were chosen from January 2010 to January 2012.70 of them received standard PCNL,another 70 cases were given tubeless PCNL.The same nursing method was given before the operation,and personalized nursing was given according to difference in operation method.A self-designed questionnaire was conducted for satisfaction degree with nursing service of all patients on discharge. Results Satisfaction degree with psychological care,catheter nursing and complication nursing of tubeless PCNL was higher than standard PCNL. Conclusions Two methods of PCNL have become conventional therapy for upper urinary calculus,and careful nursing is very important,especially for tubeless PCNL.

Objective To observe the clinical effect and comfortable degree of the mode of super hair removal. Methods The mode of super hair removal was used to depilate the hair nearby the hair line, cheeks, upper lip, beard, ventrum, areola of breast, axillary cavity, extremities, bikini area and so on. The total number of sites was 1 000. Some sites that were especially susceptible to pain, for example, upper lip and buccal region, were smeared with compound lidocaine cream for 1 hour at least before treatment. Results Hairs in the areas of extremities, ventrum, back and axillary cavity generally needed 4 to 5 times to eradicate, and the patients had no evident discomfortableness; hairs near to the upper lip and lower mandible generally needed 5 to 7 times to reach the effect which the patient was content, and anesthetics was indispensable, or the patients would present discomfortableness. Conclusions The mode of super hair removal is more effective, quicker and more comfortable in comparison with conventional methods. Therefore, it deserves to be spread.
