OBJECTIVETo observe the clinical efficacy difference in treatment of functional dyspepsia (FD) between syndrome differentiation based acupuncture and ordinary acupuncture.

METHODSSeventy FD patients were assigned to a syndrome differentiation based acupuncture group (Group A) and an ordinary acupuncture group (Group B) by Excel Software randomization. Zhongwan (RN12 ), Tianshu (ST25), and Zusanli (ST36) were needled as main points for patients in Group A. Meanwhile, different combined acupoints were needled according to syndrome differentiation. Only the same main points were needled for patients in Group B. All patients were needled once per day, 30 min each time, 6 days as one treatment cycle, 2 treatment cycles in total. Fasting serum levels of gastrin (GAS) and motilin (MTL) were determined before treatment and after 2 treatment cycles. 36-item Short-form Heath Survey (SF-36) and Nepean Dyspepsia Index [NDI, including Nepean Dyspepsia Symptom Index (NDSI) and Nepean Dyspepsia Life Quality Index (NDLQI)] were assessed before treatment, after 2 treatment cycles, and one month after treatment.

RESULTSCompared with before treatment in the same group, serum levels of GAS and MLT increased in the two groups after 2 treatment cycles (P <0. 05), but changes were more obvious in Group A (P <0. 05). Compared with before treatment in the same group, SF-36 and NDLQI score increased, and NDSI score decreased in the two groups after 2 treatment cycles and 1 month after treatment (all P <0. 05). Compared with Group B, SF-36 and NDLQI score increased in Group A after 2 treatment cycles and 1 month after treatment (P <0. 05, P <0. 01). But NDSI score at 1 month after treatment was lower in Group A than in Group B (P <0.01).

CONCLUSIONSyndrome differentiation based acupuncture could evidently improve dyspeptic symptoms of FD patients, and significantly improve their quality of life with remarkable curative effect.

Objective: To analyze and compare the features and strengths of different methods for calculating the biophysical properties of meridian points, and thus propose corresponding suggestions to fully achieve the research and application value of biophysical properties of meridian points.Methods: We searched and collected the literature on the imbalance of biophysical properties of meridian points between January 1, 2005 and March 1, 2020 in China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and PubMed database, and then analyzed, compared, and summarized the applied methods for calculating the imbalance degree of the biophysical properties of meridian points. Results: The current methods for calculating the imbalance degree of the biophysical properties of meridian points are diverse and can be summarized as the following three: direct comparison of the measured values of the left and right namesake points, difference method, and ratio method. The low uniformity of the calculation methods has limited the promotion and application of its research results. Conclusion: In future research on the biophysical properties of meridian points, multidisciplinary cooperation in terms of imbalance degree calculation methods, detection instruments, and health data models is necessary to achieve more widely applicable scientific conclusions and more generalized experimental results.

Objective:To evaluate the value of Facial Emotion Recognition Test (FERT) in the early diagnosis of behavioral variant frontotemporal dementia (bvFTD).Methods:A total of 27 patients with mild bvFTD, 27 patients with mild Alzheimer′s disease (AD) and 54 normal controls were successively collected in the Memory Clinic of Department of Neurology,Xuanwu Hospital, Capital Medical University from January 2018 to July 2019. The subjects were assessed by the FERT and a battery of neuropsychological background tests including Mini-Mental State Examination, Frontal Assessment Battery (FAB), and Auditory Verbal Learning Test (AVLT), etc. The discriminatory power of the FERT was evaluated using the receiver operating characteristic curve (ROC).Results:The average FERT scores of bvFTD, AD and control groups were 18.00 (14.00, 21.00), 25.00 (21.00, 28.00) and 28.00 (26.00, 30.00) respectively. The FERT scores of bvFTD group were significantly lower than those of control groups ( H=-55.278, P<0.001) and AD groups ( H=-28.407, P=0.002). ROC results showed that the FERT had a high discriminatory power for differentiating bvFTD from the controls, with an area under the curve (AUC) value of 0.969 (95% CI 0.931-1.000, P<0.001). Both the sensitivity and specificity were 92.6% with a cut-off value at 24. For differentiating bvFTD group from AD group, the AUC value for the FERT was 0.850 (95% CI 0.749-0.951, P<0.001), with sensitivity of 81.5% and specificity of 71.4% with a cut-off value of 22. Compared with the AUC values for the FAB and AVLT-Delayed Recall (0.776 and 0.714), the AUC value for the FERT was slightly higher, though the differences among them were not statistically significant. Conclusions:Disturbance of emotion processing is presented in the early stage of bvFTD. FERT is one of the sensitive and specific neuropsychological indicators for the early diagnosis of bvFTD.

Objective To study the relationship between the intervals of Mitomycin C treatment and cytotoxicity, apoptosis and drug resistance for bladder cancer cells.Methods The bladder transitional cell cancer line BIU-87 was treated for two hours every time for five times with intervals of 24, 48, 72 and 96 hours respectively.Cytotoxicity was measured by MTT.p53,bcl-2,Bax and p170 expression were analyzed by Western blot.Results The IC_(50)(?g/ml)were 4.41,0.71,2.83,4.51and 6.16 with treatment intervals of 24, 48, 72 and 96 hours respectively, p53 and bcl-2 were significantly down-regulated and bcl-2/Bax was re- duced at 24 hour treatment interval but not changed at 48,72 and 96 hour intervals,p170 was not detected at 24 hour treatment interval but increasingly expressed at 48,72 and 96 hours intervals.Conclusion The in- terval of Mitomycin C treatment is closely related with cytotoxieity and apoptosis and drug resistance of blad- der cancer cells.The intervals of intravesical instillations may play an important role in the effect of chemotherapy.

BACKGROUND: Although regulatory T cells (Tregs) are key to the maintenance of immunologic homeostasis and tolerance, little is known about Treg-mediated immunosuppression in the stage of sepsis. This article aimed to review the current literature on the role of Tregs in the pathophysiology of septic response, attempting to investigate the role of Tregs in immune dysfunction during sepsis. DATA SOURCES: A literature search was conducted in January 2014 using the China National Knowledge Infrastructure and PubMed. Articles on the role of Tregs in immune dysfunction during sepsis were identified. RESULTS: The identified articles indicated that Treg levels can be used for the assessment of the course of sepsis. The inhibition of Treg activity can promote the recovery of immune function. CONCLUSION: Since the mechanism of Tregs is complex during the sepsis, more studies are needed.

OBJECTIVETo study the effects of using Compound Danshen Injection (CDI) and low molecular weight heparin (LMWH) on early severe preeclampsia women.

METHODSRetrospective analysis was carried out in 95 patients with early severe preeclampsia from October 2008 to January 2011. They were assigned to 3 groups based on anticoagulant drugs. The routine therapy of magnesium sulfate (MgSO4) was given to the MgSO4 group (40 cases); the MgSO4 + CDI was given to those in the CDI group (23 cases), the MgSO4 + LMWH group was given to those in the LMWH group (32 cases). The general data of all patients were collected to analyze their effects on labor, postpartum hemorrhage, reasons for terminating the pregnancy, and maternal complications.

RESULTS(1) The average gestational week (weeks) of terminating the pregnancy was 31.7 +/- 1.9 in the MgSO4 group, 33.0 +/- 1.8 in the CDI group, and 32.8 +/- 1.7 in the LMWH group. The average weight of newborn babies (g) was 1 450.5 +/- 402.3 in the MgSO4 group, 1 582.2 +/- 332.5 in the CDI group, and 1 590.0 +/- 340.1 in the LMWH group. There was no obviously difference in the average gestational weeks or the average weight of newborn babies among the three groups. (2) The way of terminating the pregnancy was uterine-incision delivery. The main reasons for operation were sequenced as maternal complications, unsatisfied control of the blood pressure, and fetal distress. (3) The maternal complications in the three groups were sequenced as renal failure (12 cases), placental abruption (9 cases), hemolysis, increased liver enzymes and low platelet (HELLP) syndrome (8 cases). Sixteen (40.0%) had complications in the MgSO4 group, 12 (52.2%) in the CDI group, and 15 (46.9%) in the LMWH group. No statistic difference existed among the 3 groups.

CONCLUSIONSLMWH and CDI were helpful to improving the therapeutic effects of severe preeclampsia patients. They did not increase adverse drug reactions. They seemingly had effects on prolonging the gestational week.

OBJECTIVETo study the changes and clinical significance of serum levels of 25-(OH)D(3) and total IgE in children with asthma.

METHODSThirty children with asthma, 40 children with asthmatic bronchitis, and 40 healthy children were enrolled. Double-antibody radioimmunoassay was used to detect the levels of serum 25-(OH)D(3) and total IgE.

RESULTSSerum 25-(OH)D(3) levels (18±3 ng/Ml)decreased significantly in the asthmatic group compared with those in the asthmatic bronchitis group (43±3 ng/mL) and the control group (43±3 ng/mL) (P<0.01). In contrast, serum total IgE levels (192±16 IU/mL) increased significantly in the asthmatic group compared with those in the asthmatic bronchitis group (123±14 IU/mL) and the control group (118±15 IU/mL) (P<0.01). Serum 25-(OH)D(3) levels were negatively correlated with serum total IgE levels in asthmatic children (r=-0.783, P<0.01). There were no correlation between serum 25-(OH)D(3) levels and serum total IgE level in the asthmatic bronchitis and the control groups.

CONCLUSIONS25-(OH)D(3) may play an important role in the pathogenesis of asthma. The increased serum 25-(OH)D(3) level may inhibit total IgE expression, suggesting that increasing serum 25-(OH)D(3) level might be a new option for the prevention and treatment of asthma.
