Objective To evaluate the best mean for the treatment of varicocele. Methods The clini-cal effects of the high ligation of spermatic vein under the small incisal opening of the poritneum meta abdom-inal membrane and the ligation of spermatic vein under the laparoscope for the varicocele were retrospectively reviewed. The operating time, the postoperative days and the cost of hospitalization were compared of the two methods. Results Comparing with the group of operation and the group of laparoscope. Among the 158 vat-icocele patients with unilateral or bilateral varicocele, there was not statistical difference in the operating time between the two methods (P > 0. 05), whi]e there was significant difference in the postoperative days and the cost of hospitalization(P <0. 05). Conclusions When the bilateral varicoceles were simultaneously ligated, the high ligation of spermatic vein under the laparoscope was the best selection; if the unilateral varicocele was highly ligated or the patients were unconditional or the patients were not fit for laparoscopic operation, the high ligation of spermatic vein under the small incisal opening of peritoneum was the best operating method.

OBJECTIVETo observe the influence of Xinmaitong capsule (XMT) on serum matrix metalloproteinases-9, high sensitive C-reactive protein levels in patients with acute coronary syndrome.

METHOD63 cases were divided by randomized, contrastive assigned to XMT group (n = 31) and control group (n = 32). The serum levels of MMP-9 and hs-CRP before and after treatment in 12 weeks were detected.

RESULTAfter treatment, the serum levels of MMP-9 in control group had no changed and the levels of hs-CRP reduced. The serum levels of MMP-9 and hs-CRP in XMT group had significantly decreased. The serum levels of MMP-9 and hs-CRP had positive correlation, but had no correlation to levels of serum lipids.

CONCLUSIONXMT decreased breakdown of matrix collagen, and inflammatory reaction in the patients of ACS, which may have effect on plaque stabilization.

The human basic Krüppel-like factor (hBKLF) is a newly cloned human transcription factor from the cDNA library of fetal liver. It belongs to the Krüppel-like transcription factor family. Previous expression study showed that it is a hematopoietic related factor. This study was aimed to investigate the effect of hBKLF on cell proliferation, differentiation and hemoglobin synthesis by using K562 cell line as model. The sense and antisense expression plasmids of hBKLF were constructed, and transfected into K562 cells by lipofectamine. After G418 selection for 4 weeks, the cell line with stable expression of the gene was obtained. Then the hBKLF expression level, proliferation ability, colony formation and hemoglobin production were detected by RT-PCR and Western blot, MTT method, methyl cellulose semisolid culture method and benzidine test respectively. The morphologic change of cell was observed with inverted microscope. The results showed that the sense plasmid could increase hBKLF level and antisense plasmid could decrease hBKLF expression. When hBKLF level was down-regulated, K562 cells could proliferate more quickly and synthesize more hemoglobin. But there were no differences in colony formation ability and no apparent morphologic change. It is concluded that hBKLF can inhibit hematopoietic cell proliferation and hemoglobin synthesis. It is suggested that hBKLF plays an important role in the proliferation and differentiation of hematopoietic cells.

BACKGROUND: Recently, it is thought that endothelial function is a new independent risk factor of atherosclerotic disease. However, the differences in endothelial function between Tibetan and Han nationality populations have not been fully investigated.OBJ ECTIVE: To investigate the differences in endothelial function between Tibetan and Han nationality population.DESIGN: Controlled analysis.SETTING: Department of Cardiology, General Hospital; Department of Cardiology, Tibet General Hospital of Chinese PLA.PARTICIPANTS: Totally 272 Tibetan male subjects, aged (43±9) years, were enrolled in this study to stand for Tibetan nationality populations. All of them were native residents in Lhasa city. And 580 Qinghai-Tibetan railway constructers with Han nationality, aged (42±11) years, were enrolled in this study to stand for Han nationality populations. All of them were male subjects from Sichuan province and lived in Lhasa city for at least 1 year. All the participants received regular physical examination between February and May 2006 in the General Hospital of Tibet Military Area Command of Chinese PLA. All the subjects lived in the same high-altitude area (the altitude of Lhasa is 3 658 m). Informed consents were obtained from all the participants.METHODS: ①Height, body mass, waist circumference, hip circumference, systolic blood pressure(SBP) and diastolic blood pressure (DBP) were measured. Body mass index (BMI) was measured as body mass/height2. ② Measurement of brachial artery flow-mediated dilation (FMD): All the participants, who were in the fasting state, were examined in supine position following 20-minute rest. The room temperature was about 20 ℃. In the right arm, a sphygmomanometer cuff was positioned 5 cm below the antecubital fossa. A 10-MHz transducer (Vivid 7, GE Corporation, USA) was used to image the right brachial artery. After obtaining the baseline imaging, the blood pressure cuff was inflated 50 mm Hg (1 mm Hg=0.133 kPa) above the participant's SBP to occlude the brachial artery for 4 minutes. The brachial artery was then imaged during cuff inflation and 2 minutes after cuff release. After the cuff was released and reactive hyperaemia occurred, that was, flow in the brachial artery increased to accommodate the dilated resistance vessels in the forearm. In order to ensure the reliability of the data, the cuff placement and image record were performed by two designated performers. Computer-assisted analysis software was used to calculate brachial artery diameters. The absolute and relative changes of brachial artery FMD were automatically calculated out with the attached software of Vivid 7 ultrasonic diagnosis instrument. ③Biochemical study: The biochemical parameters were obtained after an overnight fasting for 12 hours. Venous blood was sampled for the measurement of total cholesterol, triglyceride (TG), high-density lipoprotein cholesterol and low-density lipoprotein cholesterol (LDL-C). ④ Analysis of variance was used to evaluate the measurement data. Chi-square statistic was used to compare enumeration data.MAIN OUTCOME MEASURES: Comparison of change in BMI, waist-hip ratio, blood pressure, blood lipid, baseline brachial diameter and brachial diameter between 2 groups.RESULTS: Totally 272 Tibetan nationality populations and 583 Han nationality populations participated in the final analysis. ① Brachial artery FMD: The baseline brachial artery diameter of Tibetan nationality populations was significantly larger than that of Han nationality population [(4.28±0.06) mm vs. (4.03±0.04) mm, t =71.915 6, P ＜0.01]; The absolute and relative changes of brachial artery of Tibetan nationality populations were significantly smaller than those of Han nationality populations, respectively [(0.124±0.005) mm vs. (0.141±0.006) mm; (2.934±0.204)% vs.(3.587±0.152)%, t = 40.582 0,52.173 2, P ＜ 0.01]. ②Physical study results: BMI and waist-hip ratio of Tibetan nationality populations were significantly larger than those of Han nationality populations [(30.1±2.5) kg/m2 vs. (26.5±3.4) kg/m2, 0.92±0.07 vs. 0.88±0.05, t =15.595 1, 9.525 4, P ＜ 0.01]. ③TG and LDL-C levels of Tibetan nationality population were (2.31±1.31) mmol/L and (3.49±0.91) mmol/L, respectively, which were significantly higler than those of Han nationality population [(1.97±1.44) mmol/L and (3.07±0.86) mmol/L, t =3.420 0, 6.522 3, P ＜ 0.01].CONCLUSION: ① Brachial artery FMD of Tibetan nationality population is poorer than that of Han nationality population,I.e. Poor vascular reactivity. ② Tibetan nationality populations have severe abdominal obesity and higher level of blood lipid as compared with Han nationality populations.

Objective To explore the effect of berberine chloride on the expression of insulin degrading enzyme (IDE) in the rat models with Alzheimer's disease (AD). Methods Eighteen adult male SD rats, weighting 220-250 g, were randomly divided into normal control group, Aβ1-40 group and Aβ40+berberine chloride group (n=6). The rat models with AD were established by stereotactically injecting condensed Aβ1-40 (5 μg) into the bilateral hippocampus of rats. The rats in the Aβ1-40+berberine chloride group were given berberine chloride (50 mg/kg) by intragastric administration once daily for 14 d. The expressions of IDE were assayed by real time polymerase chain reaction (real-time PCR) and Western blotting. Results The relative quantity of mRNA expression of IDE was (34.2±6.7) in the Aβ1-40+berberine group, which was significantly increased as compared with that in the Aβ1-40 group (45.7±12.8) and normal control group (23.4±11.3, P＜0.05). The relative quantity of protein expression of IDE was (0.61 ±0.05) in the Aββ1-40+berberine group, which was significantly increased as compared with that in the Aβ1-40group (0.46±0.07) and the normal control group (0.23±0.03, P＜0.05). Conclusion The injection of Aβ1-40 (5 μg) in the hippocampus can highly increase the expressions of IDE, thus resulting in the increase effect of Aβ clearance.

BACKGROUND AND PURPOSE: There is some controversy regarding heterozygous mutations of the gene encoding parkin (PARK2) as risk factors for Parkinson's disease (PD), and all previous studies have been performed in non-Asian populations. Dosage mutation of PARK2, rather than a point mutation or small insertion/deletion mutation, was reported to be a risk factor for familial PD; dosage mutation of PARK2 is common in Asian populations. METHODS: We performed a gene-dosage analysis of PARK2 using real-time polymerase chain reaction for 189 patients with early-onset PD or familial PD, and 191 control individuals. In the case of PD patients with heterozygous gene-dosage mutation, we performed a sequencing analysis to exclude compound heterozygous mutations. The association between heterozygous mutation of PARK2 and PD was tested. RESULTS: We identified 22 PD patients with PARK2 mutations (11.6%). Five patients (2.6%) had compound heterozygous mutations, and 13 patients (6.9%) had a heterozygous mutation. The phase could not be determined in one patient. Three small sequence variations were found in 30 mutated alleles (10.0%). Gene-dosage mutation accounted for 90% of all of the mutations found. The frequency of a heterozygous PARK2 gene-dosage mutation was higher in PD patients than in the controls. CONCLUSIONS: Heterozygous gene-dosage mutation of PARK2 is a genetic risk factor for patients with early-onset or familial PD in Koreans.

Microcopic polyangiitis (MPA) is a systemic disorder affecting small vessels. In MPA, the central nervous system involvements have rarely been reported. We experienced a case of MPA with subdural effusion and pachymeningitis in a 50-year-old woman. The diagnosis of MPA was made by the presence of mononeuritis multiplex, hematuria, pachymeningitis, and p-ANCA seropositivity in this patient. Subdural effusion was of exudates and an active suppurative inflammation was observed on the dural biopsy.

Rhesus monkeys (5 in each group) were inoculated with recombinant fusion protein of cholera toxin B subunit and multi-valent epitopes of Plasmodium falciparum intranasal or intramuscular (i.m.). Immune-responses and protective effect were evaluated. The antibody titer (Geometry mean) against CTB reached 1:512 (intranasal) and 1:10000 (i.m.) 14 day after 3rd immunization, and antibodies against P. falciparum were also elucidated, the titers in i.m. group were also significantly higher than that in intranasal group. The monkeys were challenged with 1.25 x 10(8) sporozoites of P. cynomolgi, Patent infection was observed in all 5 monkeys in control group inoculated with PBS in 10 - 14 days after challenge. Patent infection was also observed in 5 animals inoculated via intranasal and 2 animals in intramuscular group 19th days after challenge, But the infection last only 4 days in 3 animals in intranasal group and 2 animals in intramuscular group. The results demonstrated that the vaccine candidate could induce protective immune-responses in rhesus monkey against the challenge of P. cynomolgi.

OBJECTIVETo study the effectiveness and safety of immunosuppressive therapy (IST) in the treatment of childhood aplastic anemia (AA) and to study the main factors influencing the effectiveness.

METHODSThe clinical data of 55 children with severe aplastic anemia (SAA) and 51 children with chronic aplastic anemia (CAA) were retrospectively analyzed. All patients received IST from January 2007 to December 2010.

RESULTSIn children with CAA, the effective rate of antithymocyte globulin (ATG) plus cyclosporine A(CsA) combination therapy was significantly higher than that of CsA alone (80% vs 44%; P<0.05); in children with SAA, the effective rate of ATG plus CsA combination therapy was also significantly higher than that of CsA alone (75% vs 40%; P<0.05). No patients developed clonal disease such as myelodysplastic syndrome, paroxysmal nocturn hemoglobinuria or acute myelocytic leukemia. In patients treated with the ATG plus CsA combination therapy, the response rate was relatively high for children whose disease course was less than six months, bone marrow hematopoietic area was more than 40%, had no severe infections, and experienced granulocyte colony stimulating factor (G-CSF) reaction during the early treatment; however, it was not related to AA subtypes and age.

CONCLUSIONSATG plus CsA combination therapy is effective and safe in the treatment of childhood AA. The disease course, bone marrow hematopoietic area, severe infections and G-CSF reaction to early treatment are the main factors influencing the therapeutic effects.
