Objective Reports are rarely seen on the treatment of blood blister-like aneurysm(BBA)of the internal carotid artery with the overlapping low-profile visualized intraluminal support device(LVIS)stent. This study was to investigate the effects of overlapping versus non-overlapping LVIS stent-assisted coiling in the treatment of BBA. Methods We retrospectively analyzed the clinical data about 15 cases of BBA of the internal carotid artery treated in our hospital from February 2015 to February 2017,11 by o-verlapping and the other 4 by non-overlapping LVIS stent-assisted coiling. Using Raymond-Roy Occlusion Classification(RROC),we evaluated the effects of treatment immediately and at 1 week after operation. We followed up the patients from April 2015 to October 2017 and analyzed the results of follow-up digital subtraction angiogra-phy(DSA)and modified Rankin Scale scores(mRS)of the patients. Results RROC showed 10 cases of grade Ⅰ and 1 case of grade Ⅲocclusion in the overlapping group and 3 cases of gradeⅠand 1 case of gradeⅡin the non-overlapping group right after operation. In com-parison,there were 11 cases of gradeⅠin the overlapping group and 2 cases of grade Ⅰ and 2 cases of grade Ⅱ in the non-overlapping group at 1 week postoperatively.DSA at the end of the follow-up exhibited 9 cases of gradeⅠand 1 case of gradeⅡin the overlapping group and 1 case of grade Ⅰ,2 cases of grade Ⅱ and 1 case of gradeⅢin the non-overlapping group. Satisfactory prognosis was ob-served in all the 15 cases,with mRS=0 in 9 cases and mRS = 1 in 2 cases in the overlapping group and with mRS=0 in 3 cases in mRS=1 in 1 case in the non-overlapping group. Conclusion Overlapping LVIS stent-assisted coiling is safe and effective for treat-ment of BBA of the internal carotid artery.

Objective Intravascular interventional embolization has become the preferred method for the treatment of anterior communicating artery aneurysms.The purpose of this paper was to study the guiding significance of dual vessel fusion technique for in -terventional surgery of complex anterior communicating artery aneurysms. Methods A retrospective analysis was conducted on the clinical data of 31 patients with complicated anterior communicating artery aneurysms in our department from March 2015 to June 2016. All patients underwent two-vessel fusion, DSA angiography, and three-dimensional reconstruction of unilateral internal carotid artery and the images were compared to identify whether the aneurysm met the true size,the exact convergence point of bilateral A 1 and ante-rior communicating artery, anterior communicating artery aneurysm and anterior communicating artery and so on. Results There were 31 cases identified by dual vessel fusion technique on the consistency of aneurysms to true volume and 28 cases by three-dimensional reconstruction of unilateral internal carotid artery.There were 31 cases identified by dual vessel fusion technique on the exact convergence point of bilateral A 1 and anterior communicating artery and 9 cases by DSA angiography.There were 31 cases identified by dual vessel fusion technique on variations of anterior communicating artery complex and 24 cases by DSA angiography.There were 27 pa-tients who attained the optimal DSA machine projection angle by the dual vessel fusion technique which was the same as that of the unilateral internal carotid artery,in addition,the other 4 cases got better optimal DSA machine projection angle than those by three-dimensional reconstruction of unilateral internal carotid artery. Conclusion The dual vessel fusion technique helps surgeons to fully understand the anatomical relationship between anterior communicating artery complex and aneurysm,which has important guiding significance in making surgical strategies for complicated anterior communicating artery aneurysms,selecting embolization work angles and real-time observation during embolization.

Objective To observe the effect of the intensive training of core stabilization on the general function of patients with femoral neck fractures in old patients after hip arthroplasty. Methods From January, 2011 to December, 2012, 60 old patients accepted hip arthroplas-ty for femoral neck fractures were randomly divided into control group (n=30) and observation group (n=30). The control group received routine rehabilitation training 50 minutes each time, and the observation group received intensive training of core muscles 20 minutes each time based on the routine rehabilitation training 30 minutes each time, twice a day, five days a week for two weeks. Both groups were evalu-ated with Harris Hip Score (HHS), Charnley Hip Score (CHS) and modified Barthel Index (MBI) before training and one week, two weeks and three months after training. Results There was no significant difference in the scores of HHS, CHS and MBI before and one week after training (P>0.05). All the scores increased with time in both groups (F>248.165, P<0.001). The scores of HHS, CHS and MBI were signifi-cantly higher in the observation group than in the control group two weeks and three months after training (t>3.211, P<0.001). Conclusion Early intensive training of core stabilization may facilitate to recover hip function and activity of daily living in old patients after hip arthro-plasty.

Based on the principles of the in vitro staining technique, hypotonic swelling test, and water test, the Eosin Y-water test method was developed to simultaneously detect the integrity of the sperm head and tail and sperm membrane structure and function. As a widely used method in clinical laboratories in China, the Eosin Y-water test is methodologically characterized by three advantages. Firstly, both the sperm head and tail can be detected at the same time, which allows easy and comprehensive assessment of membrane damage in different parts of sperm. Secondly, distilled water is used instead of the usual formula solution to simplify and standardize the test by eliminating any potential effects on the water molecules through the sperm membrane due to different osmotic pressure or different sugar proportions and electrolyte solutions. Thirdly, the test takes less time and thus can be repeated before and after treatment. This article focuses on the fundamental principles and modification of the Eosin Y-water test and its application in sperm function examination and routine semen analysis for male infertility, assessment of the quality of sperm retrieved by testicular fine needle aspiration, semen cryopreservation program development, and evaluation of sperm membrane integrity after microwave radiation.

Increasingly accumulated results from randomized controlled trials and other clinical studies have demonstrated that male circumcision reduces the risks of acquisition and transmission of HIV, HPV, HSV-2, and other sexually transmitted infections, and thus has a potential role in preventing cervical cancer, penile cancer and prostate cancer. The prevalence of male circumcision in China is currently less than 5%. The clinical evaluation studies and randomized controlled trials of the Shang Ring device showed excellent safety profiles, extremely high acceptability, and satisfaction among the participants and service providers in Africa and China. Given the recent recommendations by the World Health Organization and the Joint United Nations Program on HIV/AIDS (UNAIDS), voluntary medical male circumcision should be promoted in China at the national level as an important alternative intervention to reduce reproductive tract infections and prevent both males and females from reproductive tract cancers. More emphasis is required on the studies of the long-term health benefits of male circumcision in uro-andrology.

The STandards for Reporting Interventions in Clinical Trials Of Moxibustion (STRICTOM), in the form of a checklist and descriptions of checklist items, were designed to improve reporting of moxibustion trials, and thereby facilitating their interpretation and replication. The STRICTOM checklist included 7 items and 16 sub-items. These set out reporting guidelines for the moxibustion rationale, details of moxibustion, treatment regimen, other components of treatment, treatment provider background, control and comparator interventions, and precaution measures. In addition, there were descriptions of each item and examples of good reporting. It is intended that the STRICTOM can be used in conjunction with the main CONSORT Statement, extensions for nonpharmacologic treatment and pragmatic trials, and thereby raise the quality of reporting of clinical trials of moxibustion. Further comments will be solicited from the experts of the CONSORT Group, the STRICTA Group, acupuncture and moxibustion societies, and clinical trial authors for optimizing the STRICTOM.

OBJECTIVETo investigate the expression variation and significance of ERK1/2 MAPK signaling transduction pathway in the pathogenesis of esophageal squamous cell carcinoma (ESCC) in Kazakh patients.

METHODSThe expression level of p-ERK1/2 after serum starvation and treatment with U0126 inhibitor was detected in esophageal cancer cell line EC9706 by Western blot assay. The mRNA level of total ERK1/2 (t-ERK1/2) and expression level of t-ERK1/2 and p-ERK1/2 proteins of 25 pairs of ESCC and adjacent normal esophageal mucosal tissues of Kazakh patients were examined and identified by real-time quantitative PCR (qRT-PCR) and Western blotting, respectively. The expression of p-ERK1/2 protein was verified by immunohistochemistry in 126 paraffin-embeded specimens, including 19 normal esophageal mucosa, 55 esophageal carcinomas in situ and 52 invasive carcinomas.

RESULTSERK1/2 MAPK signaling transduction pathway was in an active status in the EC9706 cells. The expression level of p-ERK1/2 in Ec9706 cells reached a peak at 10 min after transient serum stimulation, and p-ERK1/2 expression was totally restrained after the treatment with 50 µmol/L U0126. In the 25 pairs of ESCC and adjacent normal mucosa, the t-ERK1 mRNA level was 1.92 ± 3.49 in the ESCC tissues and 3.67 ± 7.47 in the adjacent normal mucosa. The t-ERK1 mRNA level in ESCC tissues was significantly lower than that in adjacent normal mucosa (P < 0.05), whereas there was no significant difference of t-ERK2 mRNA level between them(P > 0.05). The expression levels of p-ERK1 and p-ERK2 proteins were 0.87 ± 0.14 and 0.79 ± 0.10 in the ESCC tissues, and 1.10 ± 0.13 and 1.32 ± 0.12 in the adjacent normal mucosae. p-ERK1/2 protein in the ESCC tissues was significantly lower than that in the adjacent normal tissue (P < 0.01). However, there was no significant difference between their t-ERK1/2 protein levels (P > 0.05). In the 126 cases of paraffin-embeded specimens, positive expressions of both p-ERK1 and p-ERK2 in esophageal cancer tissues were 7.7% (4/52), significantly lower than those in adjacent normal mucosa (31.6%, 6/19) and carcinoma in situ (85.5%, 47/55, P < 0.05).

CONCLUSIONSERK1/2 MAPK signaling pathway is in an active status in esophageal cancer and adjacent normal mucosa. Our results imply that the activation of p-ERK1/2 MAPK signaling transduction pathway plays a role in the early pathogenesis of ESCC in Kazakh patients.

This study was purposed to investigate the differences of cyto biological characteristics and protein expression levels between bortezomib-resistant T-lymphoblastic lymphoma/leukemia cell lines JurkatB containing PSMB5 G322A mutation and their parent cell line Jurkat, The cytotoxicities of bortezomib and chemotherapeutic drugs to JurkatB5 cells (end selection concentration of bortezomib was 500 nmol/L), JurkatB8 (end selection concentration 800 nmol/L) and Jurkat cells were analyzed. The cell growth curves were drawn with viable cell counts by trypan blue assay, the colony formation rate were assayed by soft-agar colony culture, and the cell distributions in cell cycle were analyzed by flow cytometry, mRNA expression levels of multidrug resistance (MDR) genes MDR1, LRP and MRP were measured by real-time fluorescence quantitative RT-PCR, the differences of protein expression levels were detected by SpringBio antibody microarray containing 720 proteins. The results showed that the drug resistance multiples for 48 hours of JurkatB5 and JurkatB8 cells (relative to Jurkat) to bortezomib were increased by 33.52 and 39.04 times, respectively. JurkatB5 and JurkatB8 cells did not display significant cross-resistance to daunorubicin, adriamycin, vindesine, and etoposide after exposure for 48 hours. There were no significant differences in the cell growth curve, colony formation rate and cell distributions in cell cycle between JurkatB5, JurkatB8 and Jurkat cells (p > 0.05). There were no significant differences of mRNA expression levels of MDR1, LRP, MRP between JurkatB5 and Jurkat cells (p > 0.05). There were 264 analyzable expression points detected by antibody microarray. Among them, 252 protein expression levels were not significantly different between JurkatB5, JurkatB8 and Jurkat cells (< 2-fold), including 15 drug resistance-related proteins. 12 proteins were detected at higher or lower expression levels in JurkatB5 or JurkatB8 cells then that in Jurkat cells (cell division cycle protein 34, cell division cycle protein 37, CD34 Type II, matrix metalloproteinase-2, tenascin, Golgi complex, involucrin, histone deacetylase 1, perforin, prolactin, retinoic acid receptor β, integrin β-1), but no proteins were detected in JurkatB5 and JurkatB8 cells with higher or lower expression levels than that in Jurkat cells. It is concluded that there are no significant differences in the characteristics of cellular biology between Jurkat and JurkatB with bortezomib-resistant and PSMB5 G322A mutation. There are no significant phenotype change of MDR and overexpression of genes related to MDR in PSMB5 mutated cells. There are no significantly differential expressions of a majority of known proteins related to drug resistance, tumor cells growth, proliferation, apoptosis, malignancy degree, aggressiveness.

OBJECTIVEThe aim of this study was to explore the possibility of creating a toxin, C-CPE-ETA', by fusing C-terminal high affinity binding domain of CPE (C-CPE) with a truncated form of Pseudomonas aeruginosa exotoxin A (ETA') and to examine whether C-CPE-ETA' could specifically target CLDN-3, 4 molecule and the targeted toxin was cytotoxic against CLDN-3,4-overexpressing ovarian cancer.

METHODSCLDN-3 and CLDN-4 expressions were analyzed at the mRNA level in three ovarian cancer cell lines and epithelial ovarian cancer tissues from 20 patients. After transforming an expression plasmid of C-CPE-ETA' into E. coli BL21 (DE3) plysS strain, the recombinant protein was purified using His-Bind resin chromatography column and analyzed by Western blot and Coomassie blue staining. The specific binding, proapoptotic and cytolytic activities were evaluated by flow cytometry, fluorescence microscopy with the JC-1 probe and MTT assay in CLDN-3,4-overexpressing ovarian cancer cells.

RESULTSQuantitive RT-PCR results showed there existed high levels of CLDN-3 and CLDN-4 in ovarian cancer cells, CAOV3, OVCAR3 and SKOV3. Moreover, high expressions of CLDN-3 and CLDN-4 were observed in 90.0% (18/20) and 60.0% (12/20) of ovarian cancer tissues, with an expression level 10-fold higher than that in the normal ovarian tissue. A 58 000 recombinant protein C-CPE-ETA' was demonstrated by Western blot and Coomassie blue staining. Purified and recombinant C-CPE-ETA' was bound with high affinity to CLDN-3,4-overexpressing ovarian cancer cells, CAOV3, OVCAR3 and SKOV3 cells. C-CPE-ETA' was strongly proapoptotic and cytotoxic towards the CLDN-3,4-overexpressing ovarian cancer cells. The concentration of IC(50) was 7.364 ng/ml for CAOV3 cells, 8.110 ng/ml for OVCAR3 cells and 22.340 ng/ml for SKOV3 cells, respectively. However, control CLDN-3,4-deficient cell line HUVEC was not susceptible to the recombinant C-CPE-ETA' at a concentration up to 10 µg/ml.

CONCLUSIONSThe C-CPE-ETA' protein exhibits remarkably specific cytotoxicity for CLDN-3,4-overexpressing ovarian cancer cells. Its therapeutic potential warrants further development for ovarian cancer molecular targeted therapy.
