Objective To investigate the serum cystatin C (CysC) level and explore its relationship with cytokines and atherosclerosis (AS) in maintenance hemodialysis (MHD) patients.Methods A total of 110 stable MHD patients undergoing hemodialysis for at least six months and 60 healthy control people were enrolled in the study.Serum levels of CysC and high-sensitivity Creactive protein (hsCRP) were measured by immunoturbidimetry.The serum levels of total homocysteine (tHcy),IL-1β,IL-6 and TNF-α were determined by ELISA.Prevalence of atherosclerosis was detected by carotid ultrasonography.The relationship of CysC level and cardiac geometry incidence in MHD patients was analyzed by Logistic regression model.Results The serum CysC level was significantly higher in MHD patients as compared with healthy controls [(6.19±0.95) mg/L vs (0.76±0.21) mg/L,P＜0.01],and the serum levels of hsCRP,tHcy,IL-1β,IL-6,TNF-α were significantly higher in MHD patients than those in healthy control group (P＜0.05 or P＜0.01).The serum CysC level was higher in MHD patients with carotid artery atherosclerosis compared to patients without carotid artery atherosclerosis (P＜0.05).CysC was positively correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α respectively (P＜0.05 or P＜O.01),and was positively correlated with carotid intimal medial thickness (IMT) and AS.Besides,a negative correlation was found between the serum CysC level and the serum albumin level (P＜0.05),while CysC was positively correlated with dialysis duration,systolic pressure and iPTH (P ＜0.05).Conclusion Serum CysC level is significantly higher in MHD patients and is correlated with hsCRP,tHcy,IL-1β,IL-6,TNF-α as well as carotid artery atherosclerosis,which indicates that CysC is an independent risk factor of AS in MHD patients.

A questionnaire survey on chronic heart failure management was conducted in 110 physicians from Xindu,Supo,Jiajiang and Xinhua community hospital in Chengdu from January 2007 to June 2010.Results showed that 77.3％ (85/110) of community physicians lacked knowledge about prevention,diagnosis and treatment of chronic heart failure,and the diagnostic accuracy rate was only 51.3％ (40/78) in these community hospitals.There was lack of awareness of the guideline of chronic heart failure:the rate of β blockers use was 15.0％ (6/40) and only 5.0％ (2/40) used the target dose; the rate of angiotensin converting enzyme inhibitor use was 17.5％ (7/40) and only 7.50％ (3/40) used the target dose.In addition,90％ (99/110) of community doctors lacked the education and management for patients with heart failure.The survey suggests that the current situation of chronic heart failure management in community physicians in Chengdu is unsatisfactory.It is necessary to strengthen the training of community physicians.

Objective To investigate the influence on the ovarian reserved function of Gn-RH injection in the bilateral laparoscopic cys-tectomy. Methods The clinical data of 100 patients with endometriosis undergoing bilateral laparoscopic cystectomy were included in this study. 50 patients treated by routine bilateral laparoscopic cystectomy were set as control group. 50 patients treated by Gn-RH injection addi-tionally during the surgery were set as study group. The operative situation,serum FSH level,FSH/LH,E2 level,ovarian reserved function, pregnancy situation and recurrent rate were compared between two groups. Results The operative duration and electrocautery times in study group was significantly less than those in control group(P<0. 01). The residual ovarian tissue capsule wall thickness in study group was sig-nificantly more than that in control group(P<0. 01). At different time points,the serum FSH level,FSH/LH and E2 level in study group were significantly less than those in control group(P<0. 01,P<0. 05). The incidence of ovarian reserved function damage in study group was significantly less than those in control group(P<0. 05). The pregnancy rate was significantly higher and the time between surgery and pregnancy was significantly shorter in study group than those in control group(P<0. 05,P<0. 01). The recurrent rate in study group was sig-nificantly less than those in control group(P<0. 01). Conclusion There is a influence on ovarian reserved function of bilateral laparoscopic cystectomy. By inject Gn-RH during surgery,the ovarian reserved function could be protected,which increase the pregnancy rate and reduce recurrence.

Objective To determine the correlation between aquaporin-4 antibody (AQP4-Ab) and optic neuropathy in patients with neuromyelitis optica spectrum disorder (NMOSD).Methods The clinical and biochemical data of 53 patients with NMOSD diagnosis based on AQP4-Ab level in Changhai Hospital between January 2010 and October 2015 were retrospectively analyzed.According to optic neuropathy occurrence,the NMOSD patients were divided into optic neuropathy and non-optic neuropathy groups.Clinical and biochemical characteristics were compared between the two groups.According to the serum AQP4-Ab levels,the NMOSD patients were divided into AQP4-Ab seropositive and seronegative groups.The incidence of optic neuropathy was compared between the two groups.The correlation between optic neuropathy and AQP4-Ab levels was analyzed.Results Between the optic neuropathy and non-optic neuropathy groups,no significant differences in sex,age at onset,disease course,serum alanine aminotransferase levels,protein levels in cerebral spinal fluid,IgG index,and oligoclonal band were observed (P ＞ 0.05).However,statistically significant differences were found in frequency,superficial sensory impairment,serum creatinine level,and serum AQP4-Ab level (P ＜ 0.05).Between the AQP4-Ab sempositive and semnegative groups,a statistically significant difference in the incidence of optic neuropathy was observed (F =4.93,P ＜ 0.05).The incidence of optic neuropathy positively correlated with AQP4-Ab levels (r =0.297,P ＜ 0.05).Conclusion NMOSD patients with AQP4-Ab seropositivity could be prone to optic neuropathy,and the correlation may be beneficial to early diagnosis,therapy,and monitoring of NMOSD.

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.

OBJECTIVETo compare therapeutic effects of electroacupuncture combined with manual acupuncture and simple electroacupuncture on simple obesity.

METHODSOne hundred and twenty cases were randomly divided into an electroacupuncture plus manual acupuncture group (observation group, n = 63) and a simple electroacupuncture group (electroacupuncture group, n = 57). Their clinical therapeutic effects and the time starting the therapeutic effect were compared.

RESULTSIn the observation group 57 cases (90.5%) were cured and the total effective rate was 100.0%, and in the electroacupuncture group 42 cases (73.7%) were cured and the total effective rate was 96.5%, with significant difference in the cured rate between the two groups (P < 0.05); and the time starting the therapeutic effect in the observation group was superior to the electroacupuncture group.

CONCLUSIONElectroacupuncture combined with manual acupuncture is superior to the simple electroacupuncture in the cured rate and the time starting the effect in treatment of simple obesity.

Objective To investigate the influence of acupuncture therapy on neural stem cell (NCS) proliferation and differentiation in the hippocampus of the senescence-accelerated prone-8 (SAP8) mouse. Methods Twenty-four SAP8 mice were randomly and equally divided into a model group and an acupuncture group. Twelve senescence-accelerated resistant ( SAR1 ) mice served as the control group. Acupuncture was administered at the Baihui (DU20) point to mice in the acupuncture group once daily for 21 consecutive days. Bromodeoxyuridine (BrdU) was used to detect the proliferation and differentiation of NCSs in the hippocampus through double-labeled immunofluoresSAR1 group, the positive cells in the SAP8 group were significantly fewer Compared to the SAP8 group, positive cells markers of neuron or glia cell positive cells appeared. Compared to the SAR1 group, the expression of BrdU/GFAP increased in the SAP8 group, and decreased after acupuncture but not significantly. BrdU/S-100 β cells decreased significantly in the SAP8 group, and increased after acupuncture, but again not significantly. Compared to the SAR1 group BrdU/GalC positive cells increased significantly in the SAP8 group and decreased significantly after acupuncture.Conclusions After acupuncture treatment for 21 days, the differentiation of hippocampal NSCs into oligodendrocytes was inhibited, but there was little effect on their differentiating into neurons and immature astrocytes.
