Objective To study the mechanism of male infertility. Methods Forty sperms from 8 normal males as control and 60 sperms from 12 males with infertility were observed by SEM.The ultrastructure of acrosomes was analyzed and compared. Results Spermatozoa with obscure ringed rips in infertile group acounted for 66.7%(40/60),serrate 65.0%(39/60);but in control group,the proportions were 10.0 % (4/40) and 5.0%(2/40),respectively.The ratios of acrosome to head in infertile group were ( 70.0 ?8.0)%,greater than controls (57.7?6.4)%.The ratios of acrosome membrane which was not intact were 70.0%(42/60) in infertile group and 22.5%(9/40) in control group.Acrosomes with rough surface were 68.3%(41/60) and 20.0%(8/40) respectively in the 2 groups;Acrosomes with particles adhesive to the surface were 65.0%(39/60) and 27.5%(11/40) respectively. Conclusions Abnormal acrosome structure is one of the causes of male infertility.

Objective To explore a practicable method of serial sections of whole CNS in the rat, in which both neurons and nerve fibers were showed at the same section. Methods After perfused fixation and quick freezing, the tissues of whole CNS were cut into serial sections with cryostat followed by hematoxylin stain. Results The nerve fibers were stained in blue color while the neurons were showed black-blue and the background was light-yellow.Conclusion Our method was feasible to show both neurons and nerve fibers at the same section with quick freezing, freezing serial sectioning and improved hematoxylin staining.

Objective To investigate the efficacy of flupentixol and melitracen(Deanxit) in treatment of non-erosive reflux disease(NERD) and non-responding to proton pump inhibitor. Methods Fifty eight NERD pa-tients were randomly divided into two groups, the treatment group (n = 29) and control group (n = 29). Patients in control group were given esomeprazole 40 mg qd. Patients in the treatment group were given the same drug plus Deanxit 1 Tab qd. The clinical effect was evaluated and scored by Hemihon Anxiety Rating Scale (HAMA) after 4 weeks. Results The total efficacy rate of the treatment group was higher than control group (P < 0.01),and HAMA was lower in the treatment group than in control group (P < 0.01). Conclusions Adjuvant treatment of Deanxit combined with esomeprazole is effective to NERD patients who did not respond to proton pump inhibitor, can greatly improve anxious disorders.

ObjectiveTo investigate the risk factors of early postoperative complications after pancreaticoduodenectomy.MethodsThe clinical data of 159 patients undergoing pancreaticoduodenectomy from March 2005 to October 2010 was analyzed retrospectively.The related factors of early postoperative complications were analyzed.ResultsThe incidence rate of early postoperative complications was 30.8％ (49/159).Univariate analysis showed that preoperative fasting blood glucose level,total serum bilirubin level,serum albumin level,high density lipoproteins level and intraoperative bleeding were closely correlated with early postoperative complications in patients undergoing pancreaticoduodenectomy (P ＜ 0.05),but gender,age,preoperative jaundice,history of diabetes mellitus,operation time and whether portal vein reconstruction were no significantly associated with early postoperative complications in patients undergoing pancreaticoduodenectomy (P ＞ 0.05).Multivariate analysis showed that preoperative fasting blood glucose level( ≥6.1 mmol/L),total serum bilirubin level ( ≥ 171 μ mol/L) and serum albumin level( ＜ 35 g/L) were the important independent risk factors of early postoperative complications in patients undergoing pancreaticoduodenectomy.ConclusionThe risk factors of pancreaticoduodenectomy should be fully recognized and dealt with promptly.

The treatments for ankylosing spondylitis (AS) are still not effective, which partially due to its unclear patho?genesis. Interleukin (IL)-23/IL-17 axis is a significant immunologic pathway which has attracted much attention in the past few years. This article reviewed the role of IL-23/IL-17 axis in genetic and immunological pathogenesis of AS, and intro?duced the recent progresses in treatments of AS using anti-IL-23 or anti-IL-17 antibody. The important role of IL-23/IL-17 axis in the pathogenesis and treatment of AS indicates its potential use as a new therapeutic target.

According to the actual situation of taking part in the earthquake relief mission followed by the mobile field hospital,the characteristics of medical support mission and the main problems in the use of medical equipment of the mobile field hospital are summarized.Aimed at the problems,equipments are suggested to be added especially used for surgery,first aid,blood transfusion and some special subjects,and improvement should be made on the equipment of ultrasonic diagnosis,inspection and X-ray examination.Finally,the necessary sorts and quantity of the medical equipments needed in the mission are listed.

Objective To investigate the clinical appliance value of plantar pressure measurement in hemiplegic patients with acute cerebral infarction(ACI).Methods Plantar pressure was measurered and recorded by the means of Germany-made Zebris in 21 hemiplegic patients with ACI before and 30 d after treatment.Results Although plantar pressure on foot of the paralysed side was found remarkably decreased compared to that of the contralateral side before treatment(all P

Objective To explore the molecule mechanisms of migraine with hyperactivity of liver-yang related proteins. Methods Animal model of migraine with hyperactivity of liver-yang was established through electrical trigeminal ganglion stimulation,and by administering orally with Fuzi decoction. The total proteins of splenic lymphocytes in the rats were separated by immobilized pH gradient-based two-dimensional gel electrophoresis. With coomassie blue staining,the 2-DE images were analyzed by PDQuest 7.0 software. Matrix-Assisted Laser Desorption/Ionization-Time of Flight Mass Spectrometry (MALDI-TOF-MS) and database were used to identify the differential proteins. Result Ten differential spots protein were identified,and they were chloride intracellular channel 1,thioredoxin peroxidase Ⅰ,thioredoxin peroxidase Ⅱ,sequence 7 from patent WO9709348,Rho GDP dissociation inhibitor (GDI) alpha,actin related protein 2/3 complex neurofilament light polypeptide,proteasome subunit beta type and heat shock protein-27,annexin A1. Conclusion These protein may be involved in the development of migraine with hyperactivity of liver-yang. These data provide useful clues for elucidating the mechanisms of migraine with hyperactivity of liver-yang.

Objective To explore the clinical value of using heparin in DIC caused by Tsutsugamushi.Methods 27 cases of Tsutsugamushi with DIC were divided into two groups. The heparin treatment group(n = 15) and non-heparin treatment group(n = 12). The two groups were compared and analyzed. All the cases were diagnosed definitely depended on the "Tsutsugamushi-Disease-Diagnosis Standard".Results The group which use heparin improved in rectifying shock,terminating heorrhage,restoring the time of lab index of DIC,rating of MOF and death. Compared with the control group, the difference had statistical significance(P

Objective To develop a method detecting hMAM gene expression of breast cancer cell lines in peripheral blood.Methods The hMAM gene was cloned and confirmed by agarose gel electrophoresis and sequence analysise,the standard substance of real-time quantitative polymerase chain reaction (FQ-PCR )was prepared. The breast cancer cell lines MDA-MB453、MCF7 were cultured and the blood sample model was made.The hMAM expression of breast cancer cell lines blood model and 10 cases of breast cancer patient peripheral blood were detected by RT-PCR and FQ-PCR,GAPDH gene expression as contrast.Results The production of PCR was cloned and testified by sequence.The correlation coefficient(r) of standard curve line of FQ-PCR was -1.0. The x?s and CV were 718.9?120.5 and 16.7% respectively.The hMAM expression of one breast cancer cell lines MDA-MB453 in 104 blood cells could be detected, but not detected in the breast cancer cell lines MCF7. The hMAM expression was detected in 3 of 5 patients with sentinel nodes and in 1 of 5 patients with non-sentinel nodes.Conclusions It might be a good method for detecting breast cancer cell micrometastased in peripheral blood. The diffrernce of hMAM gene expression correlates with the type of breast cancer cell lines.
