Chinese Journal of Geriatric Heart Brain and Vessel Diseases 2017;19(9):971-973
Objective To study the diagnosis and treatment of syncope by analyzing its etiology.Methods Ninety-six syncope patients admitted to our hospital from 2014-01-01 to 2016-12-21were included in this study.The etiology of syncope was analyzed.Results Of the 96 syncope patients included in this study,50 (52.1 %) were diagnosed with nerve-mediated reflex syncope,31(32.3%) with orthostatic hypotensive syncope,10 (10.4%) with cardiogenic syncope due to arrhythmia,coronary atherosclerotic cardiopathy or pulmonary embolism,5 (5.2%) with other diseases.Conclusion Nerve-mediated reflex,orthostatic hypotension and cardiogenic factors are the causes of syncope.Attention should thus be paid to syncope caused by nervous system diseases.Clarification of the risk factors for syncope helps to reduce its potential risk.

Objective To explore the effectiveness of individual rehabilitation therapy in patients with nonspecific low back pain.Methods A total of 50 patients with nonspecific low back pain ( NLBP) between January 2013 and January 2015 were enrolled in this study.Individual rehabilitation therapy was performed based on their different pathogenesis and risk factor of low back pain.Visual analogue score (VAS),Oswestry disability index ( ODI) and Japanese orthopaedic association ( JOA) were used for the assessment of effectiveness of individual rehabilitation therapy.Results Compared with pre-rehabilitation, VAS and ODI scores were significantly decreased at two-week after rehabilitation(P<0.05),and were further decreased at six-week after rehabilitation(P<0.01).The mean score of JOA of 50 patients before rehabilitation was (10.83 ±2.94) score,which was decreased to (24.37±7.55 )score at six-week after rehabilitation(P<0.05),with 12 patients were cured,32 were improved obviously,6 were improved moderately.The rate of efficacy was 100%.Conclusion Individual rehabilitation therapy was an effective option for NLBP,with significant decrease of pain.

Objective To compare the effect of three different analgesic techniques on hyperglycemia and stress response to cholecystotomy so as to select a more reasonable analgesic modelMethods Thirty patients after cholecystotomy ,were randomly divided into three groups using three different analgesic techniques:postoperative intravenous morphine patient-controlled analgesia(PCA)(group M),postopetative epidural PCA(group E),and pre-emptive clonidine combined with postoperative epidurral PCA(group P)Blood glucose,plasma levels of stress hormones such as cotisol,insulin,glucagon,epinephrine and norepinephrine were measured at various timesResults All three analgesic techniques produced satisfactory pain reliefHyperglycemiawas inhibited more efficiently in group E and P than in group MThe secretions of stress hormoneswere less suppressed in group M than in other two groupsThe epidural analgesics requirement in group P was lower than in group E(P

To explore the anticancer effect of curcumin on human B cell non-Hodgkin's lymphoma and compare its effects on human B cell non-Hodgkin's lymphoma cells and normal peripheral blood mononuclear cells (NPBMNCs). MTT assay was used to study the effect of curcumin on the growth of Raji cells and NPBMNCs. The effect of curcumin on the apoptosis of Raji cells and NPBMNC were studied by flow cytometry and TDT-mediated dUTP nick and labeling (TUNEL). The effect of curcumin on the cell cycle of Raji cells were examined by propidium iodide staining flow cytometry. The results showed that curcumin strongly inhibited proliferation of Raji cells, 24 h IC50 for Raji cells was 22.8 +/- 1.82 micromol/L and curcumin induced Raji cell apoptosis in a time- and dose-dependent manner. Raji cells treated with curcumin showed G0/G1 or G2/M phase increase and S phase decrease. However, curcumin did not demonstrate apparent proliferation inhibition and apoptosis induction in NPBMNCs. It was concluded that curcumin is able to inhibit the proliferation of Raji cells by regulating the cell cycle and inducing the cell apoptosis. Morever, curcumin has low toxicity on NPBMNCs but can selectively induce apoptosis in Raji cells.

The anticancer activity of trichostain A (TSA) on human B cell non-Hodgkin's lymphoma and its mechanism were explored. The effect of TSA on the growth of Raji cells and normal peripheral blood mononuclear cells (NPBMNC) was studied by MTT assay. The effect of TSA on the apoptosis of Raji cells and NPBMNC was studied by flow cytometry and TDT-mediated dUTP nick end labeling (TUNEL). The effect of TSA on the cell cycle of Raji cells was studied by propidium iodide method. The results showed that TSA potently inhibited proliferation of Raji cells at microgram concentrations and induced apoptosis of Raji cells in a time- and concentration-dependent manner. Treatment with TSA induced accumulation of cells in G0/G1 or G2/M and a concomitant decrease of cell population in S phase. However, NPBMNC was less sensitive to the cytotoxic effect of TSA than Raji cells. It was concluded that TSA may inhibit the proliferation of Raji cells by regulating the cell cycle and inducing the cell apoptosis. Moreover, TSA demonstrates low toxicity in NPBMNC but selectively induces apoptosis of Raji cells.

Objective: Fungal keratitis is one of the most common diseases leading to blindness.It has a high incidence in China,and its early diagnosis and treatment are of vital importance.We aimed to investigate the value of laser confocal corneal microscopy in the clinical diagnosis of fungal keratitis.Methods: We conducted laser confocal corneal microscopy on 37 patients suspected of fungal keratitis,and compared the results with those obtained from the corneal tissue smears and fungal cultivation.Results: The fungus-infected corneas histologically exhibited defected epithelial cells,damaged subepithelial nerves and disordered stroma with reduced transparence.The hyphae showed bright,disordered,interlaced thread-or short rod-like structures.The positive rates of smear examination,fungus cultivation and laser confocal corneal microscopy were 48.65,62.16 and 78.39% for the 37 eyes,75.00,87.50 and100% for the 16 untreated eyes,and 28.57,42.85 and 61.90% for the other 21 pretreated eyes.Conclusion: Confocal laser corneal microscopy,rapid,effective and noninvasive,can be used as an important new alternative in the diagnosis of fungal keratitis

OBJECTIVE To investigate the conditions and associated risk factors of nosocomial infections caused by Stenotrophomonas maltophilia.METHODS Thirty isolates of S.maltophilia causing nosocomial infections were collected and identified with API 20NE test strips.Minimal inhibitory concentration(MIC) of 14 antimicrobial agents against 30 isolates was determined by broth microdilution method.Case-control study and multivariate Logistic regression analysis were used for statistics to verify risk factors of infections caused by S.maltophilia.RESULTS Thirty isolates of S.maltophilia were highly resistant to imipenem,meropenem,cefotaxime, aztreonam and amikacin,but showed certain susceptibility to cefoperazone/sulbactam,piperacillin/tazobactam,trimethoprim-sulfamethoxazole and ticarcillin/clavulanic acid(96.7%,76.7%,73.3% and 60.0%,respectively).The independent risk factors leading to infections of S.maltophilia were mechanical ventilation(OR=7.629) and over 60 days of length of stay(OR=4.466).CONCLUSIONS S.maltophilia shows multiresistance to commonly used antimicrobial agents.The mechanical ventilation and over 60 days of length of stay are the independant risk factors for nosocomial infections caused by S.maltophilia.
