Objective To explore the effects of ziprasidone and clozapine on serum cholinesterase (CHE) concentration in schizophrenia patients. Methods 126 schizophrenia patients were randomly divided into the observation group and the control group. The observation group was treated with ziprasidone. The control group received clozapine. The serum CHE concentration was assayed at 7, 14 and 28 days after treatment. Results ① The PANSS scores in both groups were significantly reduced after treatment, while the control group was lower than the observation group (PANSS score for positive symptoms: 15.3±4.7 vs 22.4±4.8, P<0.01; negative symptoms: 14.6±4.5 vs 21.8±5.2, P<0.01; general psychiatric symptoms: 13.3±3.4 vs 19.2±3.9, P<0.01). ② CHE levels were decreased in both groups after treatment. The control group exhibited greater decrease than the observation group. ③ The observation group had lower adverse reaction rate (34.9%) compared to control group (71.4%). Conclusion ziprasidone has weaker inhibitory effect on CHE activity compared to clozapine. This may explain that ziprasidone has lower therapeutic efficacy and better safety profile.

Objective:To analyze the mutations of globin genes among patients suspected for thalassemia from the Shanghai area.Methods:A total of 4 644 patients diagnosed at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine between June 2016 and December 2019 were selected as the study subjects. The patients were tested for common mutations associated with thalassemia gene by Gap-PCR and reverse dot blotting (RDB). Patients were suspected to harbor rare mutations based on the inconsistency between hematological phenotypes and results of common mutation detection, and were further analyzed by Gap-PCR and Sanger sequencing.Results:Among the 4 644 patients, 2 194 (47.24%) were found to carry common thalassemia mutations, among which 701 (15.09%) were α-thalassemia, 1 448 (31.18%) were β-thalassemia, and 45 (0.97%) were both α- and β-thalassemia. Forty six samples were found to harbor rare mutations, which included 17 α-globin gene and 29 β-globin gene mutations. CD77(CCC>ACC) ( HBA2: c. 232C>A) of the α-globin gene, NG_000007.3: g. 70567_71015del449, codon 102(-A) ( HBB: c. 308_308delA) and IVS-Ⅱ-636 (A>G) ( HBB: c. 316-215A>G) of the β-globin gene were previously unreported new types of globin gene mutations. Conclusion:Among the 4 644 patients, the detection rate for common thalassemia mutations was 47.24%, whilst 46 samples were detected with rare gene mutations. The type of gene mutation types were diverse in the Shanghai area. The study has provided more accurate results for genetic diagnosis and counseling.

OBJECTIVETo evaluate the effects of health promotion for eight years on cardiovascular diseases based on the changes in knowledge (K), attitude (A) and behavior (B) (KAB) before and after intervention in rural population of Fangshan, Beijing.

METHODSFive townships in Fangshan District, Beijing were divided into intervention and control communities with cluster sampling. Totally 772 farmers were selected randomly for interviews with a questionnaire of KAB, including 424 in the intervention communities (IC) and 348 in the control communities (CC) in 1992. After community-based health promotion and education on cardiovascular prevention for eight years, 895 farmers, including 431 in IC and 464 in CC, were selected randomly again in 1999 to be interviewed with the same questionnaire of KAB used in 1992.

RESULTSFrom 1992 to 1999, knowledge of cardiovascular diseases was significantly improved in residents of IC (P < 0.01) and CC. Compared to the residents in CC, there was a net increase in knowledge in residents of IC. Significant improvement was found in 10 and 11 of the 18 items of knowledge in males and females (P < 0.01), respectively. Level of knowledge in cardiovascular diseases was significantly higher in the residents of IC than those of CC in 1999. Proportions of those with positive attitudes and appropriate behaviors were significantly elevated in the residents of IC (P < 0.01), as well as prevalence of smoking and alcohol drinking decreased. However, as compared to CC, attitude and behavior in most aspects in the residents of IC changed positively, but in few aspects changed negatively. It suggested knowledge improved better than attitude and behavior changed.

CONCLUSIONSCommunity-based health promotion and education for a longer term had obvious effects on improvement of knowledge in cardiovascular disease for rural population, but slower effects on changes in attitude and behavior, which suggested there still existed certain barriers to transform knowledge into healthy behavior.

Objective To investigate the phenotypic and functional properties of in vitro-induced He-lios+regulatory T cells(Helios+iTreg) and to analyze the differences between Helios+iTreg and Helios+thymic-derived natural Treg (Helios+nTreg). Methods CD4+CD25- effector T cells (CD4+CD25- Teff) that were separated from healthy subjects were cultured with anti-CD3 and anti-CD28 antibodies and stimulated with IL-2 and TGF-β to induce the generation of Helios+iTreg. Flow cytometry and real-time PCR were respectively used to analyze the differences in phenotype and CpG methylation in Treg-specific demethylated region (TSDR) be-tween Helios+iTreg and Helios+nTreg derived from the same donor. Results CD45RA was highly expressed on Helios+iTreg, but not on Helios+nTreg. Additionally, Helios+iTreg expressed significantly higher levels of CD127,ICOS and PD-1,but lower levels of CXCR3,CCR4 and CD25 than Helios+nTreg did. IFN-γ and IL-2 that expressed by Helios+iTreg were more than those by Helios+nTreg. It was also found that the level of CpG methylation in TSDR was much higher in Helios+iTreg than in Helios+nTreg. Conclusion Both nTreg and iTreg expressed Helios,but the phenotypic and functional properties of the two Treg subsets were different. It was suggested that Helios+iTreg and Helios+nTreg might play different roles in the immune system.

Objective To evaluate the clinical value and effect of biofeedback training therapy for functional constipation in elderly patients.Methods A total of 78 elderly patients with functional constipation were treated at the People's Hospital of Pudong New Area,and were divided randomly into two groups.The control group (n =39) received routine treatment plus oral polyethylene glycol,while the experimental group (n=39) received biofeedback training treatment in addition to what was offered to the control group.After treatment,constipation symptom scores,anorectal dynamic parameters and clinical effects were compared between the two groups.Results The scores on excrement characteristics,defecation difficulty,and time and frequency of defecation were better in the experimental group than those in the control group (t=5.670,4.740,4.170,5.530;P=0.016,0.034,0.039,0.022,respectively).The overall effectiveness rate was 94.9 ％ (37/39) in the experimental group,which was higher than that (71.8 ％,2 8/3 9) in the control group (x2 =4.493,P=0.030).Meanwhile,the levels of 3 SC and 10 SC in the two groups were higher than those before treatment,but the level of 10SR was lower than that before treatment (all P＜0.05).Moreover,improvement in 3SC,10SC and 10SR were more significant in the experiment group than in the control group (all P＜ 0.05).Conclusions Biofeedback training therapy is safe and effective for elderly patients with constipation to relieve constipation symptoms,enhance control of defecation and promote defecation.

Objective To evaluate the role of combined detections of routine blood test,serum iron and hemoglobin electrophoresis in screening thalassemia in non-high incidence area.Methods Peripheral blood and serum samples of 1 000 outpatients from the department of hematology and the department of gynecology and obstetrics were obtained.Common mutations of thalassemia were detected by using GAP-PCR and reverse dot blotting,and Sanger sequencing was performed to discover rare mutations of ct-and β-thalassemia.Routine blood test,serum iron and hemoglobin electrophoresis were also performed for every patient.Results Among 1 000 samples,225 (22.5％) are detected as α-thalassemia,403 (40.3％) β-thalassemia and 15 (1.5％) composite thalassemia.Among 225 α-thalassemia patients,28 were silent,138 were intermedia,and 59 were HbH disease.Of 403 β-thalassemia,390 were carriers,7 were double heterozygote,and 6 were homozygote.In all samples,there were 357 patients detected with no common mutations,38 patients had higher result values for both MCV and MCH and none detected with thalassemia gene.There were 48 patients who had higher serum iron but normal or lower MCV,42 of them (87.5％) had thalassemia gene.Furthermore,38 patients showed abnormal hemoglobin electrophoresis,35 of them were HbH disease,while the other 3 were HbF-related thalassemia.Five patients showed abnormal hemoglobin electrophoresis,lower MCV and MCH,as well as higher serum iron,had no frequent mutation but rare ones.Conclusion Patients with higher MCV and MCH can mostly be excluded to have thalassemia,while higher serum iron represents thalassemia possibility and can provide a preliminary indication of thalassemia type,and last but not least abnormal hemoglobin electrophoresis indicates the disease.It is recommended to further carry out sequencing of rare mutations for those who had abnormal results in the combined screening,and detected with no frequent mutation.Combination of these three examinations can improve the detection efficiency of patients with thalassemia.

Objective To evaluate the clinical efficacy of different combinations with "Shugan Jianpi" acupuncture and Yintang acupoint magnetic stimulation in the treatment of depression with liver depression and spleen deficiency type.Methods 160 patients with depression treated in hospital from December 2013 to June 2017 were divided into 4 groups according to the random number table,with 40 cases in each group.Group A received basic drug therapy," Shugan Jianpi" acupuncture combined with Yintang acupoint magnetic stimulation,group B received basic drug therapy combined with Yintang acupoint magnetic stimulation,group C received basic drug therapy combined with " Shugan Jianpi" acupuncture treatment,group D was treated with basic medicine only for 4 weeks.Hamilton Depression Scale (HAMD) was used to assess the short-term and long-term efficacy for 4 groups before treatment,after 2 weeks of treatment,after 4 weeks and 2 months after treatment and the safety of these 4 types of therapy was evaluated with the side effects scale (TESS).2 months after the treatment,the quality of life universal scale (SF-36) was evaluated for patients in 4 groups.Results After 2 weeks,4 weeks and 2 months of treatment,HAMD scores in the 4 groups were significantly lower than those before treatment (P＜0.05).After 2 weeks of treatment,HAMD score of A group was (15.28±3.45),and HAMD score of B,C,D group were ((18.30±3.57),(22.50±3.71),(27.30±4.82)) respectively.HAMD score of A group was significantly lower than those of B,C,D group (P＜0.05).After 4 weeks of treatment,HAMD scores in A,B group were significantly lower than those in C,D group (P ＜0.05).After 2 months of treatment,HAMD scores in all the 4 groups were further declined compared with those after 4 weeks of treatment (P＜ 0.05),however,there was no significant difference between the four groups (P＞0.05).The scores of each dimension of SF-36 in group A were significantly higher than those of group B,C and D (P＜0.05),and which in group B and C were significantly higher than those in D group after 2 months of treatment.(P＜0.05).There was no statistical difference among the 4 groups in TESS scores (P ＞0.05).Conclusion The results suggest that there is a synergistic effect in combination of the " ShuganJianpi" acupuncture combined with Yintang acupoint magnetic stimulation in the treatment of depression of liver qi stagnation and spleen deficiency type,and it can effectively reduce the degree and improve their quality of life in patients with depression.

Objective Neuromuscular electrical stimulation(NMES)-evoked kinesthetic information in muscle spindle can be purely extracted from the mixed motor and sensory afferents using Ischemic nerve block(INB).This study aims to investigate the somatosensory cortical response evoked by NMES activating muscle spindle afferents in forearm.Methods All subjects performed four experimental tasks designed according to a 2×2 factors,including one factor of the INB state(without INB and within INB)and the other of the stimulation intensity(above and below motor threshold).During the experiment,we recorded EEG data with 64 channels and then beta event-related desynchronization(Beta ERD)were utilized quantize somatosensory cortical excitability evoked by the tasks.The subjective perception about the sensation and movement of the right hand were evaluated by a psychophysical test after the right wrist was performed by INB.Results INB significantly reduced beta ERD on the contralateral somatosensory cortex evoked by NMES above the motor threshold,and there was significant difference of NMES-evoked beta ERD values on the contralateral somatosensory cortex between above and below motor threshold.Meanwhile,contralateral dominance of NMES-evoked beta ERD on the somatosensory cortex was transferred to ipsilateral hemisphere under INB.Conclusion INB can significantly reduce NMES-evoked somatosensory cortical response above motor threshold and decrease cortical perception on the stimulus intensity,which may be due to INB resulting in rapid functional reorganization of somatosensory cortex.

To observe the protective effect of alpha-mangostin (α-MG) on focal segmental glomurular sclerosis (FSGS) induced by adriamycin.
 Methods: Adriamycin nephropathy (AN) model was induced by adriamycin (10 mg/kg) via a tail vein. Then the mice were treated with α-MG (12.5 mg/kg) or normal salin once daily for 6 weeks. At the end of 6 weeks, the mice were sacrificed, and the kidneys and blood samples were collected. Histopathology of the kidneys were analyzed under the optical microscope. The serum levels of biochemical indicators, such as serum creatinine (SCr), blood urea nitrogen (BUN) and cholesterol were determined. The levels of superoxide anion, malondialdehyde (MDA), and glutathione (GSH), the activity of superoxide dismutase (SOD) and catalase (CAT) in kidney tissues were determined. Serum levels of IL-1β, IL-18, IL-10 and adiponectin were determined. The levels of TGF-β1, collagen I (Col I), α-SMA, silent information regulator 1 (Sirt1) and the nucleotide-binding domain (NOD)-like receptor protein 3 (NLRP3) in kidney tissues were determined using immunohistochemical staining, Western blot, and RT-PCR.
 Results: The levels of SCr, proteinuria, urine protein to creatinine ratio and serum cholesterol were attenuated in AN mice after α-MG treatment, while creatinine clearance rate and serum albumin were upregulated (P<0.05). α-MG treatment alleviated the glomerular and interstitial fibrosis, downregulated the expression of fibrosis markers, such as Col I and α-SMA (P<0.05). α-MG treatment reduced the production of superoxide anion, the levels of MDA and GSH, and increased the activity of CAT and SOD (P<0.05). α-MG treatment inhibitd the generation of pro-inflammatory cytokines, such as IL-1β and IL-18 and promoted the production of anti-inflammatory cytokines, such as the IL-10 and adiponectin (P<0.05); α-MG treatment promoted the expression of Sirt1, inhibitd the expression of NLRP3 in kidney tissues (P<0.05).
 Conclusion: α-MG could attenuates FSGS of mice induced by adriamycin ameliorate and improve renal function. α-MG exerts its anti-inflammatory and anti-oxidative effects by up-regulation the expression of Sirt1 and suppression of NLRP3.
