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 choice of smoking cessation methods and its influencing factors in moderate-to-severe nicotine-dependent population.Methods·A retrospective clinical analysis was conducted for170 moderate-to-severe nicotine-dependent smoking-quitters (Fagerstr(o)m scale ≥ 4).Different smoking cessation methods (pharmacotherapy and non-pharmacotherapy) and abstinence rates of the selected population (7 d point prevalence abstinence rates and sustained abstinence rates 1,3,and 6 months after treatment) were compared and possible influencing factors were analyzed.Results·The differences in choosing the smoking cessation method in moderate-to-severe nicotine-dependent population with different ages,levels of education,and employment status were statistically significant (P=0.000).The Logistics regression analysis showed that the level of education was the major factor for choosing the smoking cessation method (P=0.006).The 7 d prevalence abstinence rate was much lower for pharmacotherapy than for non-pharmacotherapy 1 month after treatment (P=0.000) and was much higher for pharmacotherapy than for non-pharmacotherapy 3 and 6 months after treatment (P=0.000).The sustained abstinence rate was much higher for pharmacotherapy than for non-pharmacotherapy 3 and 6 months after treatment (P=0.002,P=0.000).Conclusion·For moderate-to-severe nicotine-dependent smoking-quitters,attention should be paid to the formulation and implementation of personalized strategies.The choice of smoking cessation methods depends on the age,level of education,and employment status.Reasonable pharmacotherapies can significantly increase the abstinence rate.

Objective To evaluate the clinical efficacy and safety of endoscopic submucosal dissection (ESD) guided with endoscopic ultrasonography (EUS) for rectal neuroendocrine neoplasms(NENs).Methods A retrospective analysis was performed on 58 patients with rectal ENEs who underwent ESD from January 2011 to December 2015 in JiangSu Province Hospital.Manifestations of EUS, clinicopathological characteristics, proliferation activity grade, complete resection rate, complications and follow-up results of lesion were studied.Results Those treated by ESD included 58 patients with 64 lesions of rectal NENs.EUS results showed that 3 lesions originated from mucosa, 3 from muscularis mucosa and 58 from submucosa.A total of 34 lesions located within 5 cm from anus, 26 in 6-10 cm from anus and 4 more than 10 cm from anus.All 64 lesions were successfully treated by ESD.The mean maximum diameter of the lesions was 0.8 cm(0.2-3.5 cm), and the mean procedure time was 31 min(10-60 min).The complete resection rate was 93.8% (60/64).There were 4 patients with positive basal surgical margin, and two of them underwent additional surgery and two others were treated with argon plasma coagulation after rejecting surgery and ESD.Histological examination determined that 59 lesions were pathologic grade 1(G1) and 5 were pathologic grade 2(G2).Delayed bleeding occurred in 4 cases after ESD,which was managed by medicine in 1 case and endoscopic treatment in 3 cases.No perforation occurred after ESD.During a mean follow-up period of 22.9 months(3-48 months), no lymph node metastasis or distant metastasis was observed.Conclusion EUS is able to distinguish the origin of rectal NENs and aid determining the range and depth of ESD.ESD appears to be a safe, feasible and effective procedure for providing accurate histopathologica1 evaluations as well as curative treatments for rectal NENs limited to submucosa.

To discover an efficient approach for the conversion of antibacterial fluoroquinolones into an antitumor activity, a fused heterocycle ring core, thiazolo［3, 2-b］［1, 2, 4］triazol-5-one was used as an isostere and further modified with an arylidene group. Then, 12 novel C-3 fused heterocyclic unsaturated ketones, 1- ethyl-6-fluoro-7-(4-methyl-piperazin-1-yl)-3-［6-arylidene-thiazolo［3, 2-b］［1, 2, 4］triazol-5(6H)-one-3-yl］- quinolon-4(1H)-ones(6a-6l), were designed and synthesized from pefloxacin(1). The structures were characterized by elemental analysis and spectral data, and the in vitro antitumor activity of the title compounds against SMMC-7721, Capan-1 and HL60 cell lines was evaluated. The preliminary pharmacological results demonstrated that the title compounds exhibited more significantly antiproliferative activity than the parent 1. The compounds with fluorophenyl or o-methoxyphenyl showed comparable activity to the comparasion doxorubicin. Thus, it appears to be an alternative route for a fused heterocyclic unsaturated ketone as an isostere of the C-3 carboxylic group to improve the antitumor activity.
