ABSTRACT
Objective:To evaluate the clinical effect of Huanglian-Wendan Decoction combined with Estazolam tablets in the treatment of post-stroke sleep disorders (PSSD) with syndrome of internal disturbance of phlegm-heat. Methods:A total of 96 patients with PSSD who met the inclusion criteria in the People's Hospital of Shenzhen Luohu District from September 2016 to June 2018 were randomly divided into the control group (47 cases) and the study group (49 cases) by random number table method. The control group took Estazolam tablets based on routine treatment, and the intervention group took Huanglian-Wendan Decoction based on the control group. Both groups were treated for 2 weeks. The TCM syndromes were recorded and scored before and after the treatment. The anxiety symptoms were assessed by Hamilton Anxiety Scale (HAMA) and the depression symptoms were assessed by Hamilton Depression Scale (HAMD) respectively. Sleep quality was assessed by Pittsburgh Sleep Quality Index (PSQI). The level of brain-derived neurotrophic factor (BDNF) was detected by ELISA, the level of 5-hydroxytryp-tamine (5-HT) was detected by high performance liquid-phase electrochemical detector. The adverse reactions were recorded and clinical efficacy was evaluated. Results:The total clinical effective rate of the intervention group was 91.8% (45/49), and 76.6% (36/47) in the control group. There was significant difference between the two groups ( χ2=4.227, P=0.040). After the treatment, the scores of HAMA, HAMD and PSQI in the intervention group were significantly lower than that of the control group ( t value were 4.081, 4.869 and 3.900, respectively, all Ps<0.001). The levels of serum BDNF (42.36 ± 6.78 ng/ml vs. 33.98 ± 6.41 ng/ml, t=6.217), 5-HT (127.21 ± 12.39 ng/ml vs. 101.46 ± 11.70 ng/ml, t=10.460) were significantly higher than that of the control group ( P<0.01). During the treatment, the incidence of adverse reactions was 14.9% (7/47) in the control group and 8.2% (4/49) in the intervention group, and there was no significant difference between the two groups ( χ2=1.071, P=0.301). Conclusions:Huanglian-Wendan Decoction combined with Estazolam tablets can improve the clinical symptoms, relieve anxiety and depression of PSSD patients with syndrome of internal disturbance of phlegm-heat, and improve sleep quality and clinical efficacy.
ABSTRACT
The effect of methanol addition on the heterologous expression of isoprenyl transferase NovQ was studied in Pichia pastoris Gpn12, with menadione and isopentenol as precursors to catalyze vitamin K2 (MK-3) synthesis. The expression of NovQ increased by 36% when 2% methanol was added every 24 h. The influence of initial pH, temperature, methanol addition, precursors (menadione, isopentenol) addition, catalytic time and cetyltrimethyl-ammonium bromide (CTAB) addition were explored in the P. pastoris whole-cell catalytic synthesis process of MK-3 in shaking flask. Three significant factors were then studied by response surface method. The optimal catalytic conditions obtained were as follows: catalytic temperature 31.56 ℃, menadione 295.54 mg/L, catalytic time 15.87 h. Consistent with the response surface prediction results, the optimized yield of MK-3 reached 98.47 mg/L in shaking flask, 35% higher than that of the control group. On this basis, the production in a 30-L fermenter reached 189.67 mg/L when the cell catalyst of 220 g/L (dry weight) was used to catalyze the synthesis for 24 h. This method laid the foundation for the large-scale production of MK-3 by P. pastoris Gpn12.
ABSTRACT
Objective To observe the therapeutic effect of Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets for chronic functional constipation. Methods Sixty patients with chronic functional constipation were randomly divided into treatment group and control group, 30 cases in each group. The treatment group was treated with Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets orally, and the control group was treated with oral administration of Prucalopride Succinate Tablets alone. The therapeutic effects on traditional Chinese medicine (TCM) symptoms and constipation, and the follow-up therapeutic effect of the two groups were evaluated after treatment. During the three months after the completion of treatment course, the recurrence of constipation was monitored. Results (1) The cure rate of the treatment group was 90.0％ and that of the control group was 60.0％, indicating that the therapeutic effect on TCM symptoms in the treatment group was stronger than that of the control group(P < 0.05).(2) In respect of the relief of constipation, the markedly effective rate was 93.3％ in the treatment group and was 50.0％ in the control group, and the overall effective rate was 100.0％ in the treatment group and was 73.3％ in the control group, the difference being significant between the two groups(P<0.05 or P<0.01).(3) During the treatment, the percentage of patients with weekly completely spontaneous defecation frequency ≥3 was 86.7％ in the treatment group, and was 53.3％ in the control group, the difference being significant (P < 0.05). (4) The results of 3-month follow-up after the completion of treatment course showed that one case from the treatment group had the recurrence of constipation, and the recurred cases from the control group were 6, the difference being significant (P < 0.05). Conclusion Oral use of Baizhu Shengjiang Decoction combined with Prucalopride Succinate Tablets exerts certain therapeutic effect for chronic functional constipation, which is effective both on relieving constipation symptoms and on reducing recurrence rate.
