Objective To investigate the correlation between nocturnal penile tumescence (NPT) test results and metabolic syndrome (MS).Methods In this prospective study,75 cases were enrolled,including 25 healthy volunteers (group A),25 erectile dysfunction (ED) patients with normal NPT results (group B),and 25 ED patients with abnormal NPT results (group C).At the time of recruitment,all the participants had serum total testosterone higher than 9.9 nmol/L,and were free of MS.At baseline,there was no significant differences in waistline,body mass index,fasting plasma glucose (FPG),mean arterial pressure (MAP),triglyceride,high density lipoprotein (HDL),cholesterol,and serum total testosterone among the three groups (P＞0.05).And there was no significant difference in international index of erectile function 5 score between group B and C.A follow-up survey was conducted three years after baseline to measure the above metabolic indicators and to compare the incidence of MS among the three groups.Results In the three-year follow-up survey,2 participants in group A were lost to follow-up,compared to 3 participants in group B and 5 participants in group C.In the three-year follow-up survey,there was no significant difference in all the indicators between group A and B; between group A and C,significant differences were observed in MAP,FPG,HDL,and cholesterol (P＜0.05); between group B and C,significant differences were observed in MAP and HDL (P＜0.05).In the three-year follow-up survey,2 participants in group A developed MS,compared to 3 MS patients in group B and 7 MS patients in group C.There was a significant difference in the incidence of MS among the three groups (P＜0.05).Conclusions To some extent,NPT reflects and predicts the development and progress of MS.Therefore,NPT can be used as an early indicator of MS.

?AIM: To discuss the effect of laser exposure on visual acuity and macula.?METHODS: Retrospective and consecutive case series. A retrospective analysis of 11 patients (11 eyes) with laser retinal injury was carried out from January 2014 to June 2015 in Ophthalmology Department of No. 474 Hospital of Chinese PLA. All individuals underwent visual acuity, best corrected visual acuity ( BCVA ) , and spectral-domain optical coherence tomography ( SD-OCT) for macular at first visit, and fundus fluorescein angiography ( FFA ) , visual field, and multifocal electroretinogram ( mf ERG ) were perform if necessary. Symptomatic therapies, supportive therapies and pars plana vitrectomy ( PPV ) were performed depended on the patient’s condition. The patients were followed-up at 1, 3 and 6mo after the first visit, and patients were undertaken visual acuity, BCVA, macular SD-OCT and so on.?RESULTS: Eight patients ( 73%) were under 18 years old and all patients were young males, who were injured by laser pointers when playing. Three patients ( 27%) over 18 years old were injured accidentally at work. Ten (91%) patients’ BCVA were ≤0. 3, while one ( 9%) patient’s BCVA was higher ≥0. 3. Full-thickness macular holes ( the diameter 224-519 μm ) were detected in 10 patients (91%), while sub-foveal RPE changes and IS/OS injury in 1 patient ( 9%) . Macular hole with traction or cystoid edema in 6 eyes (55%) were received PPV, while the other 5 eyes ( 4 eyes with stable macular hole and 1 eyes with RPE injury ) received conservative treatment. Macular hole closed successfully in 1 eye ( 17%) after PPV, while macular hole in the other 5 eyes ( 83%) were stable after PPV of which the cystoid edema faded. The 4 patients with macular hole and 1 patient with RPE injury were stable during follow-up period. However, the BCVA in all patients had no significant improvement at end.?CONCLUSION: Exposure to laser devices could lead to severe macula injury that could reduce central vision, which is permanent.

Objective To investigate the role of p38MAPK in the differentiation of murine osteoblasts, and to observe the expressions of receptor activator of nuclear factor-κB ligand (RANKL) and osteoprotegerin (OPG). Methods The calvarial osteoblasts of newborn BALB/c mice were cultured in MEM medium containing 10% NCS. Raloxifene (10~(-7) mol/L) and 17β-estradiol (10~(-8) mol/L) were added respectively when cells reached 70%-80% confluence combined with or without 5 μmol/L SB202190, an inhibitor of p38MAPK. The osteoblasts alkaline phosphatase activity assays were performed 72 hours later using PNPP method, and mRNA levels of alkaliphosphatase (ALP), OPG and RANKL were determined by RT-PCR. Results 17β-estradiol and raloxifene increased ALP activity and ALP mRNA level in osteoblasts in vitro which were blocked by p38MAPK inhibitor.The mRNA levels of RANKL and OPG were up-regulated by 17β-estradiol and raloxifene while the ratio of OPG/RANKL kept constant. SB202190 (5 μmol/L) inhibited the highly expressed RANKL and OPG in osteoblasts, and obviously decreased the ratio of OPG/RANKL. Conclusions p38MAPK inhibition blocked the differentiation of osteoblasts and decreased the up-regulated OPG and RANKL expressions in osteoblasts significantly (P<0.05).

Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4％ and 73.5％, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.

BACKGROUND: Pathophysiological mechanism of local microenvironment is complex after central nerve injury; especially,both inflammatory reaction at an acute phase and formation of secondary glial scar have tremendous effects on effective regeneration of axon, regeneration and arrangement of local nerve cells, proliferation and migration of local stem cells;therefore, it becomes a basic reason for blocking nerve repair in an early period. Thus, how to effectively resist inflammatory factors in injured region at an acute phase and how to optimize microenvironment of neural regeneration are the most important strategies for repairing spinal cord injury in recent years.OBJECTIVE: To design, establish and screen the best expression of interleukin-6 receptor (IL-6R) α to inhibit shRNA adenovirus expression vector by using spinal cord injury models.DESIGN: Duplicative measurement study.SETTING: Department of Spine Surgery, the Second People's Hospital of Shenzhen.MATERIALS: A total of 40 healthy Wistar rats, either gender, 8-10 weeks old, were selected in this study. Rabbit-anti-rat glial fibrillary acidic protein (GFAP) antibody Ⅰ was provided by Santa Cruz Compan; siRNA eukaryon expression plasmid pGenesil (cohtaining green fluorescent expression system) was provided by Wuhan Jingsai Bioengineering Company.METHODS: The experiment was carried out in ImmuneOpening Laboratory, Basic Medical Faulty, Tongji Medical College, Huazhong University of Science and Technology, and Medica Laboratory Center, the Second People's Hospital of Shenzhen in November 2006. Three pairs of shRNA template which composed of 19 bp reverse repeated motif of IL-6 receptor (IL-6R) α target sequence with 9 bp spacer were designed and synthesized, then the recombinant adenovirus expression vectors with green fluorescence protein were constructed in vitro respectively. The acute spinal cord injury models were completed, and the adenovirus recombinants were regionally injected post 12 hours after spinal cord injury;in addition, the inhibitory effect of RNA interference (RNAi) on expression of IL-6R in local region after spinal cord injury were detected by using real-time fluorescence quantitative reverse transcription polymerase chain reaction (RT-PCR) and Western blot so as to screen adenovirus expression vector which had the best inhibitory effect on expression of IL-6R.MAIN OUTCOME MEASURES: Inhibitory effect of RNAi on expressions of IL-6R RNA and protein in local region after spinal cord injury.RESULTS: Sequence analysis showed that IL-6R-shRNA recombinant adenovirus expression vector was successfully constructed, and optimal IL-6R-shRNA recombinant adenovirus expression vector was screened by using real-time fluorescence quantitative RT-PCR and Western blot. The IL-6R expressions were 49% and 56% at the levels of mRNA and protein, respectively.CONCLUSION: The IL-6R--shRNA recombinant adenovirus expression vector is successfully constructed and screened.The gene expression of IL-6R can be highly inhibited after acute spinal cord injury.

BACKGROUND: The comparative study concerning the safety of umbilical cord and bone marrow-derived mesenchymal stem cells transplantation for the treatment of nervous system lesions is insufficient. OBJECTIVE: To assess the safety of umbilical cord and bone marrow-derived mesenchymal stem cells transplantation for treatment of nervous system lesions. METHODS: A total of 214 cases with neuropathy were randomly divided into A, B groups. Patients in the A group received umbilical cord derived stem cell transplantation, and those in the B group received bone marrow-derived mesenchymal stem cells transplantation. Totally (5-12)×108 stem cells were transplanted into each patient. RESULTS AND CONCLUSION: The count of lymphocytes, alanine aminotransferase, aspartate aminotransferase, IgA, and IgM were increased compared with those before treatment in both groups (P < 0.01); However there were no significant differences between two groups (P > 0.05). Moreover, white blood cell count and red blood cell count in cerebrospinal fluid of all patients were significantly greater than the normal level. There were no significant differences between two groups (P > 0.05). No significant differences of the positive rate of Pandy test and the incidence rate of adverse effect were found in both groups (P > 0.05). The safety of umbilical cord and bone marrow-derived mesenchymal stem cell transplantation for treatment of nervous system lesions showed no marked differences.

Objective To summarize our experience with off-pump coronary artery bypass grafting (OPCAB) during previous 13 years. Methods Data from 3703 patients who underwent OPCAB between October 1996 and December 2008 were collected and analyzed in this study. Following perioperative variables were reviewed and evaluated: changes in the number of patients, demographic characteristics of patients, coexisting conditions such as hypertension, and diabetes, grafting options,numbers of grafts per patient, and postoperative complications and clinical outcomes. Patients were divided into four age subgroups: those who were less than 45 years were assigned to group 1, those who were 45 to 60 years were assigned to group 2,those who were 60 to 75 years were assigned to group 3, and those older than 75 years of age were assigned to group 4. Perioperative data, including the use of internal mammary artery and the constituent of the grafts, were collected retrospectively and analyzed. Results Three thousand and twenty-five patients were male (81.7%) and 678 were female ( 18.3% ), mean age was (61.35 ±9.38) years old. The number of patients who underwent OPCAB increased steadily over time. The mean grafts per patient were 3.3 ± 0.8. The use of left internal mammary artery and "hybrid" bypass grafts composed of vein and artery played a predominant role in this cohort (P<0.05) . During this period of 13 years, intra-aortic balloon counterpulsation (IABP)was performed in 41 patients and continuous renal replacement therapy (CRRT)was required in 12 patients. Main complications included rethoracotomy for bleeding and tamponade in 1.49% of patients, deep sternal wound infection requiring re-exploration in 1.38%, perioperative myocardial infarction in 1.03%, neurological adverse events in 0.62%, tracheotomy in 0.59%, acute renal dysfunction in 0.77%, and other complications in 0.77%. The overall in-hospital mortality was 0.7% (26 of 3703 patients). A trend toward a reduction in morbidity and mortality was shown in this study. Diseases associated with hospital mortality were cardiac sudden death, multiple organ dysfunction syndrome, low cardiac output syndrome, severe infection, extensive myocardial infarction and neurological adverse events. Conclusion The indications for OPCAB, an innovative revascularization strategy, have been expanded and the curative rate for OPCAB has been improved in recent years. Appropriate and practical grafting strategies, as well as complete perioperative management, are considered as contributors to the improved outcomes.
