OBJECTIVE:To provide reference for variety breeding,high yield and high quality cultivation of Momordica cochi-nchinensis. METHODS:Based on Chinese Pharmacopoeia (2015 edition,Vol Ⅰ),HPLC for determining the content of gyp-sogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis was optimized,the contents of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis from 14 production places of 8 provinces were compared,and cluster analysis was conduct-ed. Correlation of longitude,latitude and altitude with content of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchi-nensis was analyzed by SPSS17.0 software. RESULTS:Gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis showed good linear relationship in 0.05-0.5 mg/mL,regression equation was Y=4361.95X+67.3808(R2=0.9997);the limits of quantification and detection were 15.62 ng and 4.67 ng,respectively. Average recovery was 99.76%(RSD=1.36%,n=9). The content of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis from 14 production places of 8 provinces had ex-tremely significant differences(P<0.01). Clustering analysis results indicated that M. cochinchinensis from 14 production places of 8 provinces were divided into Ⅰ,Ⅱ,Ⅲ,Ⅳ groups. Contents of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochi-nchinensis of Ⅲ,Ⅳ groups were relatively high,including Guangxi Pingnan,Guizhou Jiangkou,Guizhou Dejiang,Fujian Jian-yang and Hunan Huitong,in which,Guangxi Pingnan,Guizhou Jiangkou,Guizhou Dejiang and Hunan Huitong had high altitude and low latitude,Fujian Jianyang had high altitude. The content of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochi-nchinensis was positively correlated with altitude,while negatively correlated with longitude and latitude. CONCLUSIONS:HPLC is simple,accurate and reproducible for determining the content of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochi-nchinensis,and the determined contents of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis from 14 produc-tion places of 8 provinces have reached the standard of Chinese Pharmacopoeia (2015 edition,Vol Ⅰ). Cultivation in Guangxi Pingnan,Guizhou Jiangkou,Guizhou Dejiang,Hunan Huitong and other areas with high altitude and low latitude helps to improve the content accumulation of gypsogenin 3-O-β-D-glucuronic acid methyl ester in M. cochinchinensis.

Objective To evaluate the early effect of Wallis interspinous dynamic stabilization system (Wallis system) in treatment of lumbar degenerative disease. Methods From January 2008 to Jan-uary 2009,21 patients(23 intervertebral spaces) with early lumbar disc herniation and lumbar spinal stenosis were treated with Wallis system. Four intervertebral spaces of L_(3-4) 19 intervertebral spaces of L_(4-5). Observed the time of total operation and implantation,the blood loss,and early recovery. The patients' visual analogue scale (VAS) and Oswestry disability index (ODI) scores were evaluated before and after operation. Results All patients were followed up for average (12.5 ± 0.4) months (7-18 months) after operation. The VAS and ODI scores at 7 days after operation dropped from (7.5 ± 1.5), (40.0 ± 2.0) scores before operation to (2.5 ± 0.5), (23.0 ± 1.5) scores (P < 0.01). Conclusion It is safe and easy to use Wallis system in the treatment of lumbar degenerative disease, with the advantage of mini-invasion and early effect.

Objective:To analyze the changes of thyroid volume before and after supplementation with lipiodol pills in children with goiter, and to evaluate the recovery effect of lipiodol pills supplementation on children with goiter in the short term.Methods:In October 2018, 4 townships and towns in Linxia Hui Autonomous Prefecture with relatively serious historical conditions and high goiter rate of children aged 8 to 10 were selected for thyroid examination in 19 primary schools within the jurisdiction. Sixty children with goiter were selected as research subjects; at the same time, 138 children of the same age with normal thyroid B-ultrasound examination results were selected as control in the same period. Under the condition of normal diet, children with goiter were intervened by taking 200 mg lipiodol pills at one time. After 6 months, the thyroid volume of children with goiter and control children was measured by B-ultrasound.Results:Fifty-three children with goiter were finally included, with a sex ratio of 1.00 ∶ 1.04 (26 ∶ 27). There were 138 control children in the same period, with a sex ratio of 1.00 ∶ 1.30 (60 ∶ 78). Six months after taking lipiodol pills, the median thyroid volume of children with goiter was 3.7 ml, which was significantly different from that before supplementing with lipidol pills (5.8 ml, Z = - 7.95, P < 0.001), and not significantly different from that of control children (4.1 ml) in the same period ( Z = - 0.91, P = 0.365). Among them, 90.6% (48/53) of children with goiter recovered to the normal range, and 100.0% (15/15), 81.8% (18/22) and 93.8% (15/16) children's thyroid recovered returned to the normal range in the 8-, 9-, and 10-year-old age groups, respectively, and the highest proportion was in the 8-year-old age group. Stratified by age and gender, the thyroid volume of children with goiter in all age groups and gender after supplementation with lipiodol pills was lower than that before supplementation with lipiodol pills ( P < 0.001), but there was no difference compared with the control children in the same period ( P > 0.05). After supplementing with lipiodol pills, the diameters of thyroid in children with goiter were significantly lower than those before supplementing with lipiodol pills ( P < 0.001). Compared with the control children in the same period, there were significant differences in the right width, left length and right long diameter of the thyroid ( P < 0.05). Conclusion:Supplementing lipiodol pills can restore the thyroid volume of 8 - 10 year old children with goiter to normal range in a short term, and can effectively treat simple goiter.

Objective:To explore the pathogenesis of flunarizine-induced parkinsonism from gut-brain axis perspective.Methods:Thirty male C57BL/6 mice were randomly divided into control group and flunarizine group ( n=15). Mice in the control group were given 0.1 mL 50% polyethylene glycol 400+50% saline by gavage once/d for 2 weeks, while mice in the flunarizine group were given 6 mg/mL flunarizine+50% polyethylene glycol 400+50% saline by gavage at a daily dose of 30 mg/kg for 2 weeks. Body mass was recorded 1, 3, 5, 7, 10 and 14 d after drug administration, and motor function was assessed by rotarod test 14 d after drug administration; 16s RNA sequencing was performed in the feces to observe the intestinal flora; intestinal transit function was detected by Evans blue by gavage; and then, the mice were sacrificed and homogenate or frozen sections (brain and intestinal tissues) were prepared; dopamine-ergic neuron expression was detected by Western blotting; RT-qPCR was applied to detect the expressions of inflammatory factors in the substantia nigra, and immunofluorescent staining was used to detect the expressions of ZO-1 and Claudin-5 in the intestinal epithelial tissues. Results:Compared with the control group, the flunarizine group had lower body mass ratio 1, 3, 5, 7, 10 and 14 d after drug administration (ratio to body mass before drug administration). Compared with the control group, the flunarizine group had significantly shortened residence time in rod rotating and lower rotational speed when falling ( P<0.05). Compared with the control group, the flunarizine group had decreased tyrosine hydroxylase protein in the substantia nigra without significant difference ( P>0.05). Compared with the control group, the flunarizine group had significantly increased interleukin-6 and tumor necrosis factor-α in the substantia nigra (1.00±0.00 vs. 2.79±0.83; 1.00±0.00 vs. 3.39±1.37), significantly lower intestinal Evans blue propulsion rate (80.67%±4.51% vs. 50.67%±6.03%), and statistically decreased ZO-1 and Claudin-5 expressions in the colonic epithelial tissues (27.01±1.41 vs. 16.32±2.83; 37.00±2.80 vs. 24.52±2.12, P<0.05). Totally, 576 microorganisms were noted in both control group and flunarizine group, 744 in the control group alone, and 634 in the flunarizine group alone. The intestinal flora β diversity indices in the 2 groups were significantly different based on weighted Unifrac-principle coordinates analysis (PCoA, PCoA1: 39.88%; PCoA2: 30.69%). Compared with the control group, the microbial colony structure of mice in flunarizine group was dominated by phylum thick-walled bacteria and phylum warty microbacteria, and by families Muribaculaceae, Lachnospiraceae and Akkermansiaceae. Compared with the control group, the flunarizine group had significantly decreased relative abundance of Ackermannia spp. and Lactobacillus spp. in the intestinal flora ( P<0.05). Conclusion:Flunarizine may contribute to the pathogenesis of DIP by causing structural disturbances in the intestinal flora and inducing neuroinflammation based on the gut-brain axis.
