OBJECTIVETo investigate the efficacy of the Chinese medicine Huzhangdanshenyin on male immune infertility, and provide an effective therapy for this disease.

METHODSNinety men with immune infertility were selected as the research subjects and randomly divided into two groups, 60 in the treatment group, treated by Huzhangdanshenyin, and the other 30 in the control, treated by prednisone, both for 3 months. The improvement of clinical symptoms, immunologic indexes (antisperm antibodies in serum and seminal plasma) and sperm indexes (semen liquefied duration, motility, viability, density and abnormal morphology rate) were observed and the results analyzed.

RESULTSThe total antisperm antibody reversing ratio of the treatment group was higher than that of the control (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms (P < 0.01), especially the serum antisperm antibody reversing ratio. There were significant differences in the clinical cure rate and total validity rate between the treatment group and the control (P < 0.01). After the treatment, the markers of the clinical symptoms were lower (P < 0.01), and the improvement of the clinical symptoms was better in the treatment group than in the control (P < 0.01), especially the symptoms of pain in the back and knees, distending and bearing-down sensation of the perineum and testis, hypersexuality and topalgias. Compared with pre-treatment, sperm motility and viability of the treatment group significantly improved (P < 0.01), and so did sperm density (P < 0.05). However, there were no significant differences in sperm density, semen liquefied duration, abnormal morphology rate and pH (P > 0.05) before and after the treatment.

CONCLUSIONThe Chinese medicine Huzhangdanshenyin works more effectively than prednisone in the treatment of male immune infertility. It could improve the antisperm antibody reversing ratio, clinical symptoms and signs and ameliorate sperm indexes with no obvious advierse effects.

OBJECTIVETo compare the difference between digital subtraction angiography (DSA) and type B ultrasonography in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.

METHODSNineteen patients with high voltage electrical injury of upper limbs were enrolled in the study as burn group, and another 12 healthy volunteers as controls. The endovascular membrane, vascular wall thickness, intra-vascular blood flow and endovascular thrombosis formation of ulnar and radial arteries at wound site and in regions 5, 10 and 15 cm proximal to the wounds were examined by DSA and type B ultrasonography and compared with imagings of healthy volunteers as control. The injury degree of the ulnar and radial arteries was examined during operation for evaluation to corroborate with DSA and ultrasonography findings. Necrotic and/or thrombotic vessels were excised and sent for pathomorphological examination.

RESULTSBy DSA images abnormal signs as thrombosis, vascular lumen stenosis and blood flow deceleration were found in 14 ulnar and 11 radial arteries, and the signs were more pronounced in ulnar arteries. By type B ultrasonography, abnormal signs as roughing of tunica intima, swelling or exfoliation, thickening of vascular wall, lumen stenosis, decreased blood flow, even necrosis of vascular wall and thrombosis were identified in 19 ulnar and 16 radial arteries in burn group (P < 0.05 approximately 0.01). The blood flow in ulnar artery 5 cm to the approximal part of the wound edge was obvious lower than that of the control (31.60 +/- 13.90 ml/min vs 47.70 +/- 9.60 ml/min, P < 0.05).

CONCLUSIONType B ultrasonography and DSA could be helpful in the evaluation of vascular injury in patients inflicted with high voltage electrical injury.

OBJECTIVETo investigate the possibility of applying multiplex ligation-dependent probe amplification (MLPA) to the detection of azoospermia factor (AZF) microdeletion on the Y chromosome in infertile men with azoospermia or severe oligozoospermia.

METHODSDNA samples were obtained from 147 azoospermia or severe oligozoospermia patients and 154 normal controls. After denatured at 95 degrees C, the samples were hybridized to the specific probes designed for the AZF region. With the ligase, the hybrid products were amplified by a pair of universal primers labeled with FAM fluorescence, and then separated by capillary electrophoresis for data analysis. Meanwhile all the samples were subjected to multiplex-PCR (mPCR) analysis for sequence-tagged sites (STS) in the AZF region.

RESULTSSTS deletion was detected in 22 (15.0%) of the 147 patients but not in the normal controls. By MLPA, 40 (27.2%) of the patients were found with specific probe omission in the AZF region, as compared with 20 cases in the control group.

CONCLUSIONCompared with mPCR, MLPA has a better sensitivity in detecting AZF microdeletions, and it provides more precise genetic information on the AZF regions, which may contribute to in-depth exploration into the etiological mechanism of impaired spermatogenesis.

[Objective]To investigate the characteristics of immunophenotypes in hepatocellular carcinoma(HCC) before liver transplantation.[Methods]The immunophenotypes of T-,B- cells,monocytes,dendritic cells(DC)and NK-cells in peripheral blood from 6 HCC patient who were ready to have liver transplantation and 6 healthy volunteers were analyzed by multicolor flow cytometry.[Results]In the patients,the proportions of CD4+PD-1+T cells,Treg cell (CD4+CD25+CD39+T cells),CD19+B cells,Plasmablasts(CD27highCD38highIgD-IgM-),classical monocytes(CD14high CD16-)and mature NK-cells(CD3-CD56high)were all higher than those in the healthy controls(all P<0.05).However, marginal zone B cell(CD27+IgD+),Non-switched B cells(CD27+CD38dimIgM+),intermediate monocytes(CD14high CD16+)and immature NK-cells(CD3-CD56+)were lower than those in the healthy controls(all P<0.05). And there wasn't any obvious difference in quantity being observed among other cell types.[Conclusion]There was difference in the immunophenotypes of immune cells in peripheral blood between HCC patients before liver transplantation and healthy people.And this finding exerts important effects on monitoring the immune status of the patients after liver transplantation and guiding the administrations of immunosuppressors.

OBJECTIVE: To explore the manifestations of jingjin (sinews/fascia) lesions and summarize their distribution rules in the patients with neck-type cervical spondylosis so as to provide the evidences for the development of clinical diagnosis and treatment scheme of acupuncture for cervical spondylosis. METHODS: A total of 120 patients with neck-type cervical spondylosis were collected. The meridian diagnostic method was used to examine the upper back of each patient, the manifestation category of jingjin lesions, locations and the affected muscle regions of twelve meridians were recorded. RESULTS: (1) The punctate lesions of jingjin were detected in 15 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (113 cases, 94.2% of lesion frequency). The lesion frequency of 10 regions was ≥50.0%. The punctate lesions were mainly distributed in the muscle regions of hand-shaoyang (349 cases) and foot-taiyang (333 cases). (2) The linear lesions of jingjin were detected in 10 regions, and the highest frequency of lesion occurred in the region from the inner upper corner of the scapula to Quyuan (SI 13) (77 cases, 64.2% of lesion frequency). The lesion frequency of 2 regions was ≥50.0%. The linear lesions occurred mainly in the muscle region of foot-taiyang (251 cases). (3) Eight regions were examined to be the planar lesions of jingjin, and the highest frequency of lesion was found in the site of Jianjing (GB 21) (84 cases, 70.0% of lesion frequency). The lesion frequency of 3 regions was ≥50.0%. The muscle region of foot-taiyang (260 cases) was predominated in the planar lesions. (4) The distribution of all of the punctate, linear and planar lesions of jingjin was analyzed statistically. It was found that 25 regions were involved and those with the high lesion frequency were distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13), the sites of Jianjing (GB 21) and Dazhui (GV 14), transverse processes of C₃ to C₅ and the area from the lateral border of the scapula to the teres minor, separately. The muscle regions of foot-taiyang, hand-shaoyang and hand-yangming were involved in various kinds of jingjin lesions. CONCLUSION Jingjin lesions in patients with neck-type cervical spondylosis can be divided into three categories, namely, punctate, linear and planar lesions; of which, the punctate lesions are dominated. A majority of jingjin lesions is related to the muscle region of foot-taiyang, and the lesion frequency is higher compared with the lesions to the muscle regions of hand-shaoyang and hand-yangming. Jingjin lesions are commonly distributed in the area from the inner upper corner of the scapula to Quyuan (SI 13).

Objective: To screen the differential expression profile of circular RNA (circRNA) in pancreatic cancer and analyze its potential function. Methods: Four pairs of pancreatic cancer tissues and corresponding adjacent pancreatic tissues were selected for high⁃throughput sequencing , and the differentially expressed circRNA was screened according to fold change > 2 and P < 0. 05. qRT⁃PCR was used to detect the expression of 5 randomly selected differentially expressed circRNA in 20 pairs of pancreatic cancer tissue samples. GO and KEGG enrichment analysis of differentially expressed circRNA was performed , and the top 50 circRNA⁃microRNA interaction network was constructed. The relationship between hsa_circ_0046523 and the clinicopathological features of pancreatic cancer was further analyzed , and the effects of hsa_circ_0046523 on the proliferation , migration and invasion of pancreatic cancer cells were observed by functional experiments. Results: A total of 17 182 circRNA were predicted by high⁃throughput sequencing , of which 302 circRNA were differentially expressed including 137 circRNA were upregulated and 165 circRNA were downregulated in pancreatic cancer tissues. The qRT⁃PCR results showed that the expression levels of hsa_circ_0046523 , hsa_circ_0004220 and hsa_circ_0000690 in pancreatic cancer tis⁃sues were significantly upregulated (P<0.05)，while the expression levels of hsa_ ir_0008676 and hisa _ circ_0004416 were significantly downregulated (P<0.05）.which was consistent with the sequencing results.GO analysis indicated that differentially expressed circRNA were mainly involved in substrate-dependent cell migration, protein kinase complex and cytoskeletal protein bindinig.KEGG pathway enrichment analysis showed that differentially expressed circRNA were mainly involved in protein digestion and absorption , ABC transporters , central carbon metabolism in cancer,and glycineserine and threonine metabolism pathways.The expression level of hsa_ circ_0046523 was closely correlated with tumor differentiation (P=0.002),T stage (P=0.006),lymph node metastasis (P=0.011) and TNM stage (P=0.001).Compared with HPDE6-C7 cells the expression of hsa_circ_0046523 significantly inc increased in pancreatic cancer SW1990, Mia PaCa-2BxPC-3 and Capan-2 ceIls (P<0.05). hsa_circ_ 0046523 knockdown significantly inhibited the proliferation, migration and invasion of pancreatic cancer Mia PaCa⁃2 BxPC⁃3 cells (P < 0. 05) . Conclusion There are characteristic differentially expressed circRNAs in pancreatic cancer tissues , and these differentially expressed circRNAs may be involved in the occurrence and development of pancreatic cancer.
