Objective:To investigate the clinical efficacy and safety of modified Shaoyao Gancao decoction in the treatment of hyperprolactinemia caused by amisulpride. Methods:Ninety patients with hyperprolactinemia caused by amisulpride who received treatment in Kangci Hospital from June 2018 to October 2019 were included in this study. They were randomly divided into the placebo control, control and observation groups ( n = 30/group). The placebo control group was treated with the decoction with the taste and color (without drug ingredients) similar to that of modified Shaoyao Gancao decoction. The control group was treated with Shaoyao Gancao decoction. The observation group was treated with modified Shaoyao Gancao decoction. All patients were treated for 8 weeks. Clinical efficacy, serum prolactin level and Positive and Negative Syndrome Scale score before and after treatment, Treatment Emergent Symptom Scale score after treatment, glucose and lipid metabolism, liver and kidney function before and after treatment were compared among the three groups. Results:The effective rate in the placebo control, control and observation groups was 90.0% (27/30), 96.7% (29/30) and 100.0% (30/30), respectively, and the difference among the three groups was statistically significant (χ 2 = 7.027, P < 0.05). After treatment, serum prolactin level in the observation group [(48.2 ± 15.7) μg/L] was significantly lower than that in the control group [(52.5 ± 13.7) μg/L] and placebo control group [(57.7 ± 16.9) μg/L, t = 7.134, 7.034, both P < 0.05]. After treatment, Positive and Negative Syndrome Scale score in the observation group [(51.02 ± 3.98) points] was significantly lower than that in the control group [(54.07 ± 4.19) points] and placebo control group [(58.13 ± 4.24) points, t = 5.813, 6.317, both P < 0.05]. After treatment, Treatment Emergent Symptom Scale score in the observation group [(5.2 ± 1.3) points] was significantly higher than that in the control group [(4.9 ± 1.4) points] and placebo control group [(4.4 ± 1.2) points, t = 7.011, 7.231, both P < 0.05]. After treatment, blood glucose, low-density lipoprotein cholesterol, triglyceride, total cholesterol, alanine aminotransferase, aspartate aminotransferase levels in the observation group were significantly lower than those in the placebo control and control groups (all P < 0.05). Serum level of high-density lipoprotein cholesterol in the observation group was significantly higher than that in the placebo control and control groups (both P < 0.05). Conclusion:Modified Shaoyao Gancao decoction is highly effective in the treatment of hyperprolactinemia caused by amisulpride. It can reduce serum prolactin level and has good safety.

Objective To analyze the clinical data of diagnosis and treatment of Wegener' s granulomatosis (WG) in order to understand the nature of this disease. Methods The clinical data including clinical manifestations,laboratory findings imaging features,pathological changes and efficacy of treatment of 34 patients with WG admitted from January 2002 to March 2012 were analyzed.Results Of the 34 patients,male to female ratio was 18 to 16,and the average age subjected to WG onset was (45 ± 15)years old ranged from 18 to 81 years old.The average duration before the diagnosis confirmed was ( 140 ±72) mouths,while 29.4％ was diagnosed within 3 months. The presenting symptoms included initial involvements in lung (41.1％),nose (38.2％ ),eyes ( 11.7％ ),ear (8.8％ ) and constitutional symptoms such as fever (26.4％ ). Throughout the whole disease course,the incidence of systemic impairments were as follows:lung (76.4％),nose (73.5％),kidney (67.6),eyes (58.5％),ear (47.0％),nervous system (41.1％),oral ulcer (20.5％ ).Of laboratory findings,C - ANCA/PR3 -ANCA was positive in 61.7％ patients,P - ANCA/MPO - ANCA positive in 20.5％ patients,ANCA negative in 11.7％ patients,P- ANCA positive with MPO- ANCA negative in one patient (2.9 ％ ) and C -ANCA positive with PR3 and MPO positive in one patient (2.9％ ).Of imaging findings,nodules or masses were most commonly observed (34％), followed by fibrotic lesions (20.5％ ), cavitations ( 17.6％ )、opacities ( 17.6％ ).Typically pathological triad ( vasculitis,necross and granuloma formation)was found in one patient ( 4.3％ ),while two pathological changes of the triad occurred in 10 patients (43.4％). Pulmonary infection was highly prevalent (50％), and of them,20.5％ patients were misdiagnosed as tuberculosis,malignancy or abscess.After admission,high dose of corticosteroids and cyclophosphamide were administered as bolus and maintenance therapy. Plasma exchange,intravenous immunoglobulin,and rituximab were added for refractory cases and optimal response were obtained in most cases.Conclusions Wegeners granulomatosis is a clinically complicated entity and sometimes can have progression,leading to misdiagnosis. Early and prompt use of steroids and cyclophosphamide may confer good therapeutic efficacy and avoid life -threatening complications.

Objective To study the mechanism of some vegetables inhibiting human platelet aggregation function.Methods Some vegetable juice was mixed(tomato juice as positive control)with platelet-rich plasma(PRP),and maximum ratio of platelet aggregation was measured after induction by agonists on the aggregometer.The expression levels of platelet activation marker were detected,including fibrinogen receptor(Fib-R),P-selectin(CD62P),and the combination amount of fibrinogen on the surface of platelet by flow cytometry to validate the inhibitory effect of platelet aggregation by animal tests.Ordinary white rabbits were randomly divided into five groups,each group was fed with saline,cooked tomato juice,blanched garlic leaves juice,Chinese cabbage juice or spinach juice,respectively.And the maximum ratio of rabbit platelet aggregation in different time were observed.Results Cooked vegetable juice couldn't inhibit human platelet aggregation induced by AA,but blanched garlic leaves juice,Chinese cabbage juice and spinach juice could inhibit human platelet aggregation obviously induced by ADP.collagen or epinephrine.The inhibition intensity of platelet aggregation increased markedly along with the increase of the concentration of the cooked vegetables juice.Cooked juice of blanched garlic leaves,Chinese cabbage,spinach could not inhibit the expression of Fib-R and CD62P,Whereas they were able to significantly decrease the amount of Fib-R and fibrinogen binding. ADP-induced rabbit platelet aggregation ratios in the group fed with cooked juice of blanched garlic leaves,Chinese cabbage or spinach were significantly lower than control group after 3,5,8 weeks,respectively.The inhibition ratios of the platelet aggregation in cooked Chinese cabbage juice group were 45.7%,53.6%,48.5% after 3,5,8 weeks,respectively.Cooked juice of blanched garlic leaves group were 10.7%,66.7%,46.3%,respectively. Cooked spinach juice group were 8.7%,21.0%,42.6%,respectively.The collagen-induced rabbit platelet aggregation ratios in the groups fed with cooked juice of blanched garlic leaves or Chinese cabbage were significantly lower than control group after 5 and 8 weeks respectively. The inhibition ratios of the platelet aggregation in cooked Chinese cabbage juice group were 54.9%,56.3%after 5 and 8 weeks,respectively. Cooked juice of blanched garlic leaves group were 28.4%and 86.7%,respectively. Cooked tomato juice could not inhibit rabbit platelet aggregation in 8 weeks. Conclusions After induced by ADP or collagen,cooked juice of blanched garlic leaves,Chinese cabbage and spinach could significantly decrease the amount of Fib-R and fibrinogen binding,and inhibit platelet aggregation function significantly.It may have potential application of therapy or prlevention of thrombotic diseases.

Objective To investigate the correlation of prognosis with the immunophenotype in acute myeloid leukemia(AML)patients.Methods Immunophenotyping was performed in 131 patients with AML by mtdtieolor flow cytometry.Correlation of immunophenotype with other laboratory parameters such as initial white blood cell count(WBC),platelet count(PLT),hemoglobin(Hb),and the complete remission(CR)ratio was analyzed.Results In these AML patients,myeloid antigens CDl3,CD33 and myeloperoxidase(MPO)were more highly expressed than other antigens.Expression of CD34 and HLA-DR were lower in acute promyelocytic leukemia(M3)subtype.The expression of lymphocyte antigen CD19 and CD7 were the highest.CD7 expression was associated with age(t=-2.27,P＜0.05).CD14 was associated with initial WBC(Z=-2.284,P＜0.05).The overall CR ratio was 56.5%among all patients.CD34positive patients had a significantly lower CR rato(45.1%),compared with the CD34 negative patients whose CR ratio was 75.6%(x2=11.524,P=0.001).The CR ratio was significantly lower in cases expressing both CD34 and HLA-DR(74 patients with CR rate 41.9%)than in cases expressing only CD34 or HLA-DR(38 patients with CR rate 78.9%)and both negative(19 patients with CR rate 68.4%)(Z=-3.492,P＜0.01).However,other antigens,including CD7,CD19,CD13,CD33,CD38,CD15,CD64,CD14 and MPO had no significant association with CR ratio.Logistic regression analysis showed that age(60 years or older),initial WBC(more than 50 x 109/L),PLT(more than 30 x 109/L),Hb(less than 60g/L)and CD34 were independent adverse factors for achieving CR.Conclusions In AML patients,age,initial WBC,PLT,Hb and CD34 are associated with CR ratio.Detection of immunophenotype may help to estimate prognosis of patients with AML and guide the treatment of AML.

Objective:To explore the relations among screen-based sedentary behaviors ( SSB) , family factors and body mass index ( BMI) of children, and to study how family factors have effect on BMI through influencing SSB. Methods:A total of 1 846 students aged 7-11 years from 12 primary schools in one district of Beijing were included. Their body weight and height were measured to calculate the BMI. The time of SSB and family factors were investigated by using questionnaires. The time of SSB was the total time of watching TV and videos, playing computer games and iPad each day during the past 7 days recalled by children. The family factors included the parents’ education, occupation, the parents’ time of SSB, whether the parents told their child the harm of SSB, the parents’ time limit for the children’ s SSB. The parents’ education and occupation were used for calculating the family socioeconomic score. Results:The median time of SSB for children was 1 hour/day, and the interquartile range was 1 hour/day. The BMI of the children with the parents’ time limit for the children’ s SSB less than 120 min/day were smaller than the children with the parents’ time limit not less than 120 min/day, in both the boys (1. 63 kg/m2,P<0. 001) and the girls (0. 85 kg/m2, P=0. 004). The family socioeconomic score, the parents’ SSB time, whether the parents told their children the harm of SSB were not related to the children’ s BMI . The mediation effects of SSB time for children on the association between the parents’ time limit for the children’s SSB and BMI were-0. 222 kg/m2(95%CI:-0. 432, -0. 095) for boys and-0. 187 kg/m2 (95%CI: -0. 507, -0. 049) for girls , which accounted for 13. 67% of the total effects for boys and 22. 11% for girls. Conclusion:The parents’ time limit for the children’ s SSB has effect on their BMI through influencing their SSB time. Parents’ supervision on the behaviors of children produces larger benefit for BMI than health education conveyed by parents. Therefore, parents’ participation in su-pervising the behaviors of children are indispensable for preventing and controlling childhood obesity.

OBJECTIVE:To establish a method for simultaneous determination of residual methylparaben,ethylparaben,nipa-sol and benzalkonium chloride in marketed eye drops. METHODS:HPLC method was adopted. The determination was performed on Hypersil GOLD C18 column with mobile phase consisted of 0.005 mol/L ammonium acetate(10 mL triehtylamine in 1 L solu-tion,pH adjusted to 5.0±0.5 with glacial acetic acid)-acetonitrile(45:55,V/V)at the flow rate of 1.0 mL/min. The detection wave-length was 262 nm(methylparaben,ethylparaben,nipasol)and 214 nm(benzalkonium chloride),respectively. The column tem-perature was 30 ℃ and sample size was 20 μL. RESULTS:The linear range were 1.2350-15.4380 μg/mL for methylparaben(r=0.9999),1.3170-16.3836 μ g/mL for ethylparaben (r=0.9997),1.2072-15.0894 μ g/mL for nipasol (r=0.9996) and 17.776-222.0 μg/mL for benzalkonium chloride(r=0.9999),respectively. Limits of quantitation were 2.0,2.0,2.0,1.11 μg,re-spectively;limits of determination were 0.375,0.375,0.375,0.333 μg,respectively. RSDs of precision,stability and reproducibili-ty tests were all lower than 2.0%. The average recoveries were 98.14%-102.48%(RSD=1.6%,n=9),98.79%-102.42%(RSD=1.3%,n=9),98.19%-102.49%(RSD=1.5%,n=9)and 98.76%-100.53%(RSD=0.6%,n=9),respectively. CONCLUSIONS:The method is accurate,reproducible,simple and suitable for the determination of residual methylparaben,ethylparaben,nipasol and benzalkonium chloride in marketed eye drops.

Objective To evaluate the efficacy and safety of oral prednisone in patients with relapsing neuromyeli?tis optica. Methods Seventeen patients with relapsing neuromyelitis optica receiving long-term oral prednisone had been followed. The Expanded Disability Status Scale (EDSS) and annualized relapse rates were used to evaluate curative effect. Results During long-term oral prednisone treatment, patients had a significant reduction in the EDSS [(3.09 ± 0.85) vs. (4.06 ± 0.80), P<0.05] and the median annualized relapse rate was significant reduced [(0.34 ± 0.31) vs. (1.51 ± 0.57), P<0.005]. But the effect of different dosage of prednisone on annualized relapse rates was not different. No severe adverse re?actions were observed. Conclusions Treatment with long-term oral prednisone in patients with NMO significantly reduces relapse rates, improves neurological function and the treatment was well-tolerated.
