The chemical constituents were systematically separated from the roots of Berberis polyantha by various chromatographic methods, including silica gel column chromatography, HP20 column chromatography, polyamide column chromatography, reversed-phase C_(18) column chromatography, and preparative high-performance liquid chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic techniques(1D NMR, 2D NMR, UV, MS, and CD). Four phenylpropanoids were isolated from the methanol extract of the roots of B. polyantha, and they were identified as(2R)-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone-O-β-D-glucopyranoside(1), methyl 4-hydroxy-3,5-dimethoxybenzoate(2),(+)-syringaresinol(3), and syringaresinol-4-O-β-D-glucopyranoside(4). Compound 1 was a new compound, and other compounds were isolated from this plant for the first time. The anti-inflammatory activity of these compounds was evaluated based on the release of nitric oxide(NO) in the culture of lipopolysaccharide(LPS)-induced RAW264.7 macrophages. At a concentration of 10 μmol·L~(-1), all the four compounds inhibited the LPS-induced release of NO in RAW264.7 cells, demonstrating potential anti-inflammatory properties.

OBJECTIVE: To investigate the effect of laparoscopic high ligation of spermatic cord vein in patients with chronic prostatitis and varicocele prostatitis. METHODS: A total of 90 varicocele patients were selected from January 2016 to December 2020, including 33 patients with chronic prostatitis. Changes of white blood cell count, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score and serum testosterone level in the expressed prostate secretion (EPS) were observed before and after the operation of laparoscopic high ligation of spermatic vein. RESULTS: All patients were followed up three months after the surgery. There was no significant difference in the white blood cell counts in EPS, NIH-CPSI score, and serum testosterone level in patients with varicocele-only who underwent high ligation surgery after the operation. However, the white blood cell count in the EPS of patients with chronic prostatitis was lower than that before 3 months of operation ( ［12.39±4.23］×109/L vs ［21.36±5.05］×109/L). The NIH-CPSI score was significantly lower than that before operation ( ［12.71±6.21］ vs ［26.76±8.43］). And the serum testosterone level was higher than that before operation (［4.34±1.77］ng/ml vs ［2.36±1.05］ng/ml). CONCLUSION Laparoscopic high ligation of the spermatic vein in patients with chronic prostatitis and varicocele could effectively reduce the number of white blood cells in the EPS, boost the level of serum testosterone and improves symptoms of chronic prostatitis.

Objective:To evaluate the clinical efficacy and safety of Longmu Zhuanggu granule for the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency. Method:This multicenter stratified， block-randomized， double-blind， double-dummy， positive drug （pidotimod granule） parallel controlled， and non-inferiority trail intended to included 240 children patients and divided them into the experimental group （n=120） and the control group （n=120） at the ratio of 1∶1. Patients in both groups were treated for eight successive weeks and followed up for 12 months. The cure rates， numbers of respiratory infections， average courses of disease， curative effects of traditional Chinese medicine （TCM） syndrome， curative effects of individual symptoms， curative effects of immune indexes， and safety indexes between the two groups were observed and compared. Result:A total of 237 subjects were collected from 10 research centers， including 119 cases in the control group and 118 in the experimental group. There were 236 cases enrolled into the full analysis set （FAS）， 210 into the per-protocol set （PPS）， and 236 into the safety set （SS）. The baseline data of the two groups were not significantly different from each other， indicating that they were comparable. The cure rates of the experimental group and control group were 75.21% （88/117） and 73.95%（88/119）， respectively， with the 95% confidence interval （CI） of difference between the two groups being 1.26% （-9.85%，12.37%） for FAS and 3.81% （-6.28%，13.90%） for PPS. The 95% CI fell within the 10% non-inferiority margin， implying that non-infertility test of the cure rate in the treatment of endpoint disease was valid， and the conclusions of FAS and PPS analysis were consistent. There was no significant difference in the number or course of upper respiratory infection， bronchitis， and pneumonia. The difference in curative effects of TCM syndrome between the two groups after four weeks of treatment was not remarkable. After eight weeks of treatment， the total effective rate of the experimental group was 84.62%（99/117）， statistically higher than 78.15%（93/119） of the control group（χ²=-3.26，P<0.05）. There were no significant differences in the disappearance rates of individual symptoms between the two groups after four weeks of treatment. After eight weeks of treatment， the experimental group and control group exhibited the disappearance rates of 67.50%（54/80） and 47.37%（36/76） for shortness of breath and laziness to speak， 75.00%（54/72） and 53.33%（40/75） for poor appetite， 54.55%（60/110） and 37.84%（42/111） for hyperhidrosis， respectively， with obviously better outcomes observed in the experimental group （P<0.05，P<0.01）. The inter-group comparison revealed significant differences in immune indexes after eight weeks of treatment. As demonstrated by comparison with the situations before treatment， IgA， IgG， IgM， and CD4 did not change significantly after treatment. Except for CD8 in the experimental group (P<0.05), there was no significant difference in other immune indexes before and after treatment There was no significant difference in the incidence of adverse reactions. Conclusion:Longmu Zhuanggu granule is not inferior to pidomod granule in the treatment of children recurrent respiratory infection due to lung-spleen Qi deficiency， and it exhibits good safety， implying its promising clinical application value.

Objective:To introduce the construction of Henan Cerebral Palsy Register and Rehabilitation Management System (HCPRRMS) and to explore the construction project of regional register and surveillance of cerebral palsy. Methods:The construction process, registration content and preliminary results of HCPRRMS were systematically introduced. Results:HCPRRMS was independent developed in 2014. Since March, 2015, the system has been used to register information of patients with cerebral palsy in the Third Affiliated Hospital of Zhengzhou University. Until September, 2019, a total of 23 child rehabilitation institutions had used the registration management system. There were 1357 patients with cerebral palsy registered in this system, in which 936 cases (68.98%) were male, 501 cases (36.92%) were with gestational weeks < 37, 443 cases (32.65%) were with birth weight < 2500 g, and 430 cases (31.69%) were born with hypoxic-ischemic encephalopathy. Among them, the spastic cerebral palsy patients (1117 cases, 86.74%) accounted for the highest proportion. There was significant difference among types of cerebral palsy and the classification of GMFCS. A total of 1117 patients with cerebral palsy showed MRI-identified brain abnormalities, in which, periventricular leukomalacia accounted for the most (480 cases). For the complications, epilepsy accounted for 14.44% (196 cases), vision impairment accounted for 8.03% (109 cases), hearing impairment accounted for 11.64% (158 cases). Among 769 cases aged more than two years, language-speech dysfunction accounted for 52.66% (424 cases); and among 216 cases aged more than four years, mental retardation accounted for 37.96% (82 cases). Conclusion:HCPRRMS could help to understand the risk factors, clinical characteristics, and complications of cerebral palsy.

Objective To explore the clinical characteristics of autoimmune disease with dual seropositive antibodies of leucine-rich glioma inactivated 1(LGI1)and contactin-associated protein 2(Caspr2).Methods The clinical data of seven patients with dual seropositive LGI1 and Caspr2 antibodies who were admitted to the Neurology Department of Peking Union Medical College Hospital from July 2014 to December 2017 were retrospectively analyzed.Results Central,peripheral and autonomic nervous systems were all involved in the seven cases;100%(7/7)presented with insomnia,myokymia,neuropahic pain and hyperhydrosis;71%(5/7)showed memory decline or psychiatric and behavioral symptoms;57%(4/7)had urinary hesitation or constipation;and 43%(3/7)had seizure.Electromyography showed 100%(6/6) of the patients had prolonged afterdischarges following normal M waves and/or abnormal spontaneous firing.Electroencephalography revealed slow waves or basic rhythm slowing in 71%(5/7)of patients.Electrocardiography showed sinus tachycardia,axis deviation,and prolonged QT intervals in 71%(5/7)of patients.One patient died from arrhythmia before immunotherapy.One died from pulmonary infection after immunotherapy.Improvement with immunotherapy was documented in the other five cases.No relapse was noted during the 1-2-year follow-up.Conclusions Autoimmune disease with dual seropositive antibodies of LGI1 and Caspr2 can diffusely affect the central,peripheral,and autonomic nervous systems.The possibility of this disease should be considered in patients with acute and subacute onset of neuropsychiatric symptoms,especially in patients with accompanying insomnia,myokymia,and hyperhydrosis.

In this study,liquiritigenin sulfonation was characterized using recombinant human sulfotransferases( SULTs). The chemical structure of liquiritigenin sulfate was determined by ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry( UPLC-Q-TOF-MS/MS). Then model fitting and parameter estimation were performed using the Graphpad Prism V5 software. Various SULT enzymes( SULT1 A1,1 A2,1 A3,1 B1,1 C2,1 C4,1 E1 and 2 A1) were able to catalyze the formation of liquiritigenin-7-O-sulfate. Sulfonation of liquiritigenin-7-hydroxy( 7-OH) by these eight SULT enzymes consistently displayed the classical Michaelis-Menten profile. According to the intrinsic clearance( CLint) value,the sulfonation rates of liquiritigenin-7-OH by expressed SULT enzymes followed the following rank order: SULT1 C4 > SULT1 A3 > SULT1 E1 > SULT1 A1 > SULT1 A2 > SULT1 B1 >SULT1 C2>SULT2 A1. Further,liquiritigenin-7-O-sulfonation was significantly correlated with the SULT1 A3 protein levels( P<0. 05).Then,human embryonic kidney( HEK) 293 cells over expressing SULT1 A3( named as HEK-SULT1 A3 cells) were conducted. As a result,liquiritigenin-7-O-sulfate( L-7-S) was rapidly generated upon incubation of the cells with liquiritigenin. Consistent with SULT1 A3,sulfonation of liquiritigenin-7-OH in HEK-SULT1 A3 cells also followed the Michaelis-Menten kinetics. The derived Vmaxvalues was( 0. 315±0. 009) μmol·min-1·g-1,Kmwas( 7. 04±0. 680) μmol·L^-1,and CLintwas( 0. 045±0. 005) L·min^-1·g^-1. Moreover,the sulfonation characters of liquiritigenin( 7-OH) in SULT1 A3 were strongly correlated with that in HEK-SULT1 A3 cells( P<0. 001).The results indicated that HEK-SULT1 A3 cells have shown the catalytic function of SULT1 A3 enzymes. In conclusion,liquiritigenin was subjected to efficient sulfonation,and SULT1 A3 enzyme plays an important role in the sulfonation of liquiritigenin-7-OH. Significant sulfonation should be the main reason for the low bioavailability of liquiritigenin. In addition,HEK-SULT1 A3 cells were conducted and successfully used to evaluate liquiritigenin sulfonation,which will provide an appropriate tool to accurately depict the sulfonation disposition of liquiritigenin in vivo.

Objective To measure the upper airway of obstructive sleep apnea hypopnea syndrome by 256 slice spiril CT, and to access the airway obstruction plane with the airway plane data in OSAHS patients.Through these measurements, we can provide assistance for clinical diagnosis and treatment.Methods This study randomly selected 178 patients diagnosed with OSAHS and 110 cases non-snoring healthy people as the control group by the Philips 256 slice CT.Under the nasopharyngeal area, velopharyngeal area, glossopharyngeal area, epiglottis area, we measured the cross-sectional area and volume of the narrowest plane in the two groups of quiet respiration and Müller status.Results The OSAHS group underwent quiet respiration and Müller status during CT scanning, and the two states about epiglottis area in cross-sectional area and volume had no significant difference, Other groups had differences between the parameters.There was a significant difference in the volume about velopharyngeal area and glossopharyngeal area. In the control group undergoing quiet respiration and Müller status during CT scanning, there was difference in velopharyngeal cross-sectional area.Other parameters had no significant difference.Conclusions The obstruction plate of OSAHS patients with 256-slice spiril CT measurement is mostly in the velopharyngeal area and glossopharyngeal area. The volume measurement of upper airway by CT can predict airway obstruction plate in patients with OSAHS.

Background: Prospective real-life data on the safety and effectiveness of rituximab in Chinese patients with diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) are limited. This real-world study aimed to evaluate long-term safety and effectiveness outcomes of rituximab plus chemotherapy (R-chemo) as first-line treatment in Chinese patients with DLBCL or FL. Hepatitis B virus (HBV) reactivation management was also investigated. Methods: A prospective, multicenter, single-arm, noninterventional study of previously untreated CD20-positive DLBCL or FL patients receiving first-line R-chemo treatment at 24 centers in China was conducted between January 17, 2011 and October 31, 2016. Enrolled patients underwent safety and effectiveness assessments after the last rituximab dose and were followed up for 3 years. Effectiveness endpoints included progression-free survival (PFS) and overall survival (OS). Safety endpoints were adverse events (AEs), serious AEs, drug-related AEs, and AEs of special interest. We also reported data on the incidence of HBV reactivation. Results: In total, 283 previously untreated CD20-positive DLBCL and 31 FL patients from 24 centers were enrolled. Three-year PFS was 59% (95% confidence interval [CI]: 50-67%) for DLBCL patients and 46% (95% CI: 20-69%) for FL patients. For DLBCL patients, multivariate analyses showed that PFS was not associated with international prognostic index, tumor maximum diameter, HBV infection status, or number of rituximab treatment cycles, and OS was only associated with age >60 years (P < 0.05). R-chemo was well tolerated. The incidence of HBV reactivation in hepatitis B surface antigen (HBsAg)-positive and HBsAg-negative/hepatitis B core antibody-positive patients was 13% (3/24) and 4% (3/69), respectively. Conclusions: R-chemo is effective and safe in real-world clinical practice as first-line treatment for DLBCL and FL in China, and that HBV reactivation during R-chemo is manageable with preventive measures and treatment.
