Objective To understand the status quo and demanding of resident pension service in Chongqing urban communities to provide the reference for constructing the community pension service system.Methods The questionnaire survey was conducted on 1 080 residents aged 50 years old or older in the nine districts of Chongqing City.Results 89.1％ of the respondents didn't have any pension service,but the currently facing maximal difficulty Was the low proportion of medicare reimbursement,the main service that the elderly wanted to get was life care,security safeguards services and ordinary medical help;73.4％ of the respondents were willing to try the integrated pension service model.Conclusion The government or related departments should optimize new pension resources,increase the funding sources,make reasonable overall planning and construct the pension service model.

OBJECTIVETo observe the therapeutic effect of acupuncture on gastrointestinal dysmotility in liver cirrhosis.

METHODSForty cases of gastrointestinal dysmotility in liver cirrhosis were randomized into an acupuncture group and a motilium group, 20 cases in each one. In the acupuncture group, on the basis of the conventional treatment, electroacupuncture was applied at Zusanli (ST 36), Sanyinjiao (SP 6) and Taichong (LR 3) for 30 min, once a day. In the motilium group, on the basis of the conventional treatment, motilium was taken orally 30 min before meals, 10 mg each time, three times a day. The treatment was required for 2 weeks in both groups. The changes in the digestive tract symptom score and liver function Child-Pugh score were observed and the efficacy was assessed.

RESULTSThe total effective rate of digestive tract symptoms was 85.0% (17/20) in the acupuncture group and 70.0% (14/20) in the motilium group. The score improvements in abdominal distention, belching and vomiting in the acupuncture group were superior to those in the motilium group (all P < 0.05). In the acupuncture group, the liver function Child-Pugh total score was 8.40 +/- 0.22 before treatment and reduced to 5.36 +/- 0.17 after treatment, in which the scores for ascites, serum bilirubin and albumin were all reduced (all P < 0.05) and the reducing range was increased in tendency with the improvements in digestive tract symptoms. In the motilium group, Child-Pugh score was not changed obviously as compared with that before treatment. CONCLUSION Acupuncture effectively alleviates digestive tract symptoms and improves liver function for the patients of liver cirrhosis, its efficacy on gastrointestinal dysmotility in liver cirrhosis is superior to motilium.

Objective:To evaluate clinical efficacy of bipedicled scrotal flaps combined with keystone-design perforator island flaps in repairing postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum.Methods:Clinical data were collected from 6 male patients with extramammary Paget′s disease of the perineum in Dermatology Hospital of Jiangxi Province from February 2018 to March 2019, and analyzed retrospectively. These patients were aged from 70 to 84 years (median, 77.5 years) , skin lesions involved the mons pubis, penis and scrotum, and the area of postoperative skin defects varied from 18 to 133 cm 2 (median, 96 cm 2) in size. In all the patients, mons pubis defects after tumor resection were repaired with abdominal keystone-design perforator island flaps, and scrotal and penile defects were repaired with bipedicled scrotal flaps using the remaining scrotal tissues. These patients were followed up at 1 and 3 months after surgery and every 3 months thereafter. Results:All the 6 patients were followed up for 3 - 36 months, with an average of 10 months. All flaps survived with a good color and texture match, and favorable function and appearance were achieved in both the donor and recipient sites.Conclusions:The bipedicled scrotal flaps combined with keystone-design perforator island flaps can repair postoperative large-area defects in male patients with extramammary Paget′s disease of the perineum. Moreover, the operation is simple, and good blood supply can be achieved.

OBJECTIVETo investigate the effects of microwave irradiation on the expression and regulation of heat shock proteins (HSPs) in primary cultured rat hippocampal neurons.

METHODSNeurons were exposed to 90 mW/cm(2) microwave irradiation for 10 minutes. Western blot was used to determine the expression of HSP27, HSP70, HSP90 and heat shock factor 1 (HSF1) at 0, 3, 6, 12 and 24 hour respectively. Real-time RT-PCR was used to determine the mRNA expression of HSF1. DNA-binding activity of HSF1 was measured by electrophoretic mobility shift assay (EMSA).

RESULTSThe protein expression of HSP27 was significantly increased by 22%, 36%, 18% at 3, 6, 12 h, respectively (P < 0.05). The protein expression of HSP70 was significantly increased by 23%, 32%, 26% at 3, 6, 12 h, respectively (P < 0.05, P < 0.01). The protein expression of HSP90 was significantly increased by 27%, 33% at 6, 12 h, respectively (P < 0.05, P < 0.01). The DNA-binding activity of HSF1 was stimulated, however, no significant change of the expression of HSF1 was observed on both the mRNA and protein levels.

CONCLUSIONThe transcriptional activity of HSF1 is activated by microwave irradiation, which promotes the expression of HSPs. Heat shock response which contributes to establish a cytoprotective state is induced by microwave irradiation in primary cultured rat hippocampal neurons.

OBJECTIVETo explore the clinicopathological correlation between CD4(+) T lymphocyte count and superficial lymphadenopathy HIV/AIDS patients.

METHODSA total of 1066 HIV/AIDS patients were included in this study. The incidence of superficial lymphadenopathy, peripheral blood CD4(+) T lymphocyte counts and histological features of superficial lymphadenopathy were analyzed.

RESULTSAmong 1066 patients, 126 cases (11.8%) presented with superficial lymphadenopathy. Of the 126 cases, there were 69 cases with CD4(+) T lymphocyte counts < 100/µl and clinical diagnoses including tuberculosis (37 cases), reactive hyperplasia (8 cases), AIDS-related lymphadenopathy (18 cases), penicillium diseases (12 cases), fungal infection (5 cases) and non-tuberculous mycobacterial infection (1 case). Twenty-six cases had CD4(+) T lymphocyte counts between 100/µl to 200/µl and clinical diagnosis including tuberculosis (12 cases), reactive hyperplasia (8 cases), AIDS-related lymphadenopathy(6 cases), penicillium disease (2 cases) and non-Hodgkin lymphoma (1 case). Twenty-nine cases had CD4(+) T lymphocyte counts > 200/µl and clinical diagnoses including tuberculosis (11 cases), reactive hyperplasia (12 cases), AIDS-related lymphadenopathy (3 cases), Penicillium diseases (1 case) and non-Hodgkin lymphoma (4 cases). The CD4(+) T lymphocyte counts among patients with tuberculosis, AIDS-related lymphadenopathy and Penicillium diseases were significantly different (χ(2) = 8.861, P = 0.012). A significant correlation between the incidence of superficial lymphadenopathy and CD4(+) T lymphocyte counts was found (χ(2) = 375.41, P = 0.000).

CONCLUSIONSThe most common cause of superficial lymphadenopathy in HIV/AIDS patients is tuberculosis, followed by lymph node reactive hyperplasia, AIDS-related lymphadenopathy and Penicillium disease. Low CD4(+) T lymphocyte count correlates with an increased incidence of superficial lymphadenopathy and the risk of opportunity infection. Therefore, determination of peripheral blood CD4(+) T lymphocyte count should become an integral marker for the early diagnosis and treatment of superficial lymphadenopathy in HIV/AIDS patients.

OBJECTIVEThe aim of this study is to explore the cytotoxic effect of CD8+ T subsets in peripheral blood with chronic hepatitis B subjects who are at immune tolerance phase and immune clearance phase (before and after three months' treatment with interferon-alpha), further to investigate their impact in the pathogenesis of chronic hepatitis B and antiviral therapy.

METHODSThe subjects of chronic hepatitis B, including 20 subjects of immune tolerance phase and 20 subjects of immune clearance phase, are enrolled in the study. And we use flow cytometry to detect Lysosome-associated membrane protein-1 (LAMP-1, CD107a) and Granzyme B (GrB) expression of CD8(high) and CD8(low) T cells in peripheral blood with chronic hepatitis B subjects.

RESULTS(1) At immune clearance phase, the CD8+ T subsets expressing GrB and CD107a are higher than counterpart of immune tolerance phase. (2) At immune tolerance phase and immune clearance phase in HBV infection, the CD8(low) T cells expressing GrB and CD107a are higher than that of CD8(high) T cells. (3) After three months' treatment with interferon-a, except for GrB+ CD107a+ CD8(high) T cells, CD8(high) T cells expressing GrB and CD107a present a tendency of ascensus at the same time with that of CD8(low) T cells a tendency of descensus except for GrB(-)CD107a+ CD8(low) T cells. (4) The CD8+ T cell expressing GrB and CD107a, correlate positively with HBV DNA load at immune tolerance phase, but correlated negatively at immune clearance phase.

CONCLUSIONS(1) GrB and CD107a molecule expressed by different CD8+ T cell subsets play an important role in disease evolution and antivirus therapy of chronic hepatitis B, the cytotoxic effect of CD8(high) T cell subset became more and more stronger during the treatment of IFN-alpha, and the cytotoxic effect of CD8(low) T cell subset couldn't be neglected before antivirus therapy. (2) To some degree, the correlation between HBV-DNA load and the expression of GrB and CD107a at different CD8+ T cell subsets, could hint the relationship between virus and immune response.

OBJECTIVETo explore the pathophysiological and biomechanical features of skeletal muscular injury for providing a rational basis for its treatment, prevention and rehabilitation.

METHODSIn 70 adult rabbits, the left tibialis anterior (TA) muscle was stretched to injury, while the right TA muscle served as control. Histological, enzymohistochemical and biomechanical changes were observed on days 0, 1, 2, 3, and 7 after injury. Cytochrome oxidase (CCO), acid phosphatase (ACP), ATPase, succinate dehydrogenase (SDH), malate dehydrogenase (MDH), NADH-diaphorase (NADHD), glutamatedehydrogenase (GDH), alpha-glycerophosphate dehydrogenase (alpha-GPD) and lactate dehydrogenase (LDH) were measured. The examined biomechanical parameters included maximal contractile force, ultimate load, length, energy absorption, tangent stiffness, and rupture site.

RESULTSPartial or complete rupture of TA muscle occurred near the muscle-tendon junction. There was an intense inflammatory reaction on day 1 and 2 after injury. Endomysium fibrosis and myotube formation were observed on day 3, and developed further on day 7. The activity of cell oxidases (CCO, ATPase, MDH, alpha-GPD, SDH, NADHD and GDH) showed a significant drop from day 0 to 2, and resumed with different levels on day 3. The increment of enzymatic activities continued on day 7 and the levels of NADHD and alpha-GPD reached to the levels of control muscle. Maximal contractile force was 70.17%+/-3.82% of controls immediately after injury, 54.82%+/-3.09% at 1 day, 66.41%+/-4.36% at 2 days, 78.39%+/-4.90% at 3 days and 93.64%+/-5.02% at 7 days. Ultimate load was 85.78%+/-7.54% of controls at the moment of injury, 61.44%+/-5.91% at 1 day, 49.17%+/-4.26% at 2 days, 64.43%+/-5.02% at 3 days, and 76.71%+/-6.46% at 7 days.

CONCLUSIONSEndomysium fibrosis and scar formation at the injured site are responsible for frequent recurrence of skeletal muscle injury. Recovery of tensile load slower than that of maximal contractile force may be another cause. Whether the injured muscle returns to normal exercise is mainly determined by the tensility on which the muscle-tendon can bear rather than the maximal contractile force.
