ObjectiveThis paper aims to investigate and evaluate the staged efficacy and safety of the representative empirical prescription of the “Zhu Ke Jiao” theory， Qijia Rougan prescription， combined with entecavir in the treatment of hepatic fibrosis in chronic hepatitis B. MethodsA multicenter randomized controlled clinical study was conducted， and 101 patients diagnosed with chronic hepatitis B-related hepatic fibrosis （CHB-HF） who met the diagnosis and inclusion criteria were randomly assigned to an observation group （Qijia Rougan prescription + entecavir） and a control group （entecavir）. The treatment duration was 24 weeks. Liver stiffness measurement （LSM）， fibrosis-4 index （FIB-4）， portal vein diameter， hepatitis B serology， biochemical indicators， hepatic fibrosis markers in serum ［hyaluronic acid （HA）， laminin （LN）， procollagen Ⅲ peptide （PⅢP）， and type Ⅳ collagen （Ⅳ-C）］， and traditional Chinese medicine syndrome scores were used as efficacy evaluation indicators. Efficacy assessments and explorations of different staged subgroups of Qijia Rougan prescription were conducted according to LSM values based on the Metavir pathological staging standard. ResultsA total of 98 cases were included for statistical analysis， with 49 cases in the observation group and 49 in the control group. The general data of the patients in both groups were comparable. Compared with the same group before treatment， the observation group showed a significant reduction in LSM and FIB-4 （P<0.01）， as well as notable improvements in LN， Ⅳ-C， and various TCM syndrome scores （P<0.05， P<0.01）. When compared to the control group after treatment， the observation group demonstrated significant improvements in LSM， FIB-4， and various TCM syndrome score indicators （P<0.05， P<0.01）， indicating that the observation group performed better than the control group. Subgroup analysis of the regression of hepatic fibrosis stages showed that compared to the same group before treatment， the observation group had better improvement in regression of stages F2 and F3 （P<0.05）. When compared to the control group after treatment， the observation group exhibited superior improvement in regression of stage F3 （P<0.05）. No adverse events occurred in either group during the treatment period. ConclusionCompared with entecavir alone， the combination of Qijia Rougan prescription and entecavir significantly improves the degree of hepatic fibrosis and clinical TCM symptoms in patients. The optimal intervention period is primarily during stage F3， which is a potential “interception” point of the “Zhu Ke Jiao” theory.

OBJECTIVE To analyze the quantity transfer rule in the processing of Astragalus membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. METHODS Three batches of A. membranaceus decoction pieces processed through moistening-soaking and steaming-soaking followed by cutting were prepared. The HPLC overlapping fingerprints of A. membranaceus and its decoction pieces were established through the Similarity Evaluation System of Chromatographic Fingerprints of TCM （2012 edition）. Combined with the previous qualitative analysis results， the common peaks were identified， the changes of common peak area were analyzed， and the principal component analysis was carried out. The contents of calycosin-7-glucoside， astragaloside Ⅰ and astragaloside Ⅳ in A. membranaceus and its decoction pieces were determined by HPLC， and the content differences of each component in different samples were compared. RESULTS The results of fingerprint analysis showed that 17 common peaks were identified. After steaming-soaking and moistening-soaking of A. membranaceus， the proportion of common peak area in the decoction pieces changed compared with the original medicine （for example， in A. membranaceus steaming-soaking decoction pieces， the proportion of peak area of malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ decreased， while the proportion of peak area of calycosin-7-glucoside increased）. The results of principal component analysis showed that A. membranaceus， and its decoction pieces after moistening-soaking and steaming-soaking followed by cutting were all clustered into one category respectively. The results of content determination showed that， compared with A. membranaceus， the average content of calycosin-7-glucoside in A. membranaceus moistening-soaking decoction pieces was significantly reduced （P＜0.05）； the average contents of calycosin-7-glucoside and astragaloside Ⅳ in A. membranaceus steaming- soaking decoction pieces were significantly increased （P＜0.05）； there was no significant difference in the average content of astragaloside Ⅳ in A. membranaceus moistening-soaking decoction pieces and astragaloside Ⅰ in the two decoction pieces （P＞ 0.05）. CONCLUSIONS There are differences in the quantity transfer rules of A. membranaceus before and after moistening-soaking and steaming-soaking followed by cutting. Steaming-soaking followed by cutting may make the transformation of unstable components （such as malonyl calycosin-7-glucoside and malonyl astragaloside Ⅰ） more complete.

Bamboo leaf flavonoids(BLF)are compounds extracted from bamboo leaves,possessing properties including antioxidant,antimicrobial and anti-inflammatory properties.This study aimed to investigate the effects of BLF on liver damage,antioxidant function,and related gene expression in rats induced by diquat(DQ).Thirty-two 5-week-old male Sprague-Dawley(SD)rats were randomly divided into four experimental groups:the control group(Con),1 000 mg/kg BLF group(BLF),DQ stress group(DQ),and 1 000 mg/kg BLF+DQ stress group(BLF-DQ).The results showed that compared to the Con,the DQ group exhibited significantly decreased serum AST lev-els(P＜0.05),as well as decreased levels of T-AOC,GPX,SOD,and CAT in the liver(P＜0.05),and increased MDA levels in rats(P＜0.05).Additionally,the gene expression levels of HO-1,GPX,CAT,SOD1,and Nrf2 in the liver were significantly reduced(P＜0.05).In contrast,1 000 mg/kg BLF significantly decreased serum AST and ALT levels(P＜0.05),increased levels of T-AOC,GPX,CAT,and SOD in liver(P＜0.05),and significantly increased gene expression of HO-1,GPX,CAT,SOD1,Nrf2,and NQO1(P＜0.05).Compared to the DQ group,BLF-DQ significant-ly decreased liver index(P＜0.05),reduced serum AST and ALT levels(P＜0.05),increased lev-els of CAT,GPX,and T-AOC in liver(P＜0.05),decreased MDA levels(P＜0.05),and signifi-cantly upregulated gene expression levels of HO-1,GPX,CAT,SOD1,and Nrf2(P＜0.05).These findings indicated that BLF alleviate liver damage caused by DQ stress in rats,improve liver an-tioxidant function inhibition,activate the Nrf2 signaling pathway and PINK/Parkin mitophagy-re-lated gene expression.

Objective:To compare ocular surface dry eye-related indexes and tear cytokine level changes in chronic ocular graft-versus-host disease (oGVHD) patients after receiving topical treatment of 0.05% cyclosporine or 0.1% tacrolimus eye drops.Methods:A randomized controlled study was conducted.A total of 60 chronic oGVHD patients (60 eyes) were recruited at Beijing University Third Hospital from April 2020 to April 2021.The patients were divided into tacrolimus group and cyclosporine group by a random number table, with 30 patients (30 eyes) in each group.Patients in tacrolimus group used 0.1% tacrolimus eye drops (twice a day) and patients in cyclosporine group used 0.05% cyclosporine eye drops (4 times a day).Additionally, 0.1% flumetholon (twice a day), deproteinized calf blood extract (3 times a day), and 0.1% sodium hyaluronate eye drops (8 times a day) were applied for anti-inflammation and lubrication in both groups.Patients were screened according to exclusion criteria after 1-month treatment.Eventually, 21 patients (21 eyes) in tacrolimus group and 12 patients (12 eyes) in cyclosporine group were included for further study.Patients were examined before and 1 month after treatment.The primary evaluation indexes included Ocular Surface Disease Index (OSDI), corneal fluorescein staining scores and tear film break-up time (BUT).Expressions of interleukin (IL)-6, IL-8, IL-17, epidermal growth factor (EGF), and tumor necrosis factor-α (TNF-α) in tears were detected before and after treatment using Luminex chip.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Peking University Third Hospital (No.M2020489).Written informed consent was obtained from each subject before any medical examination.Results:The OSDI differences between before and after treatment were 0.4(-5.6, 2.5) in tacrolimus group and 27.2(4.6, 45.0) in cyclosporine group, and the OSDI improvement was significantly greater in cyclosporine group than in tacrolimus group ( Z=-2.547, P=0.009).The differences of corneal fluorescein staining scores and BUT between before and after treatment were 5.0(2.5, 10.0) scores and 3.5(-0.5, 13.8) seconds in tacrolimus group, 0.0(-3.0, 0.0) scores and -1.5(-3.0, 0.0) seconds in cyclosporine group, respectively, with no significantly difference between both groups ( Z=-0.526, -0.804; both at P>0.05).The differences of IL-6, IL-8, IL-17, EGF and TNF-α expressions between before and after treatment in tacrolimus group and cyclosporine group were not significantly different ( Z=-0.487, -0.112, -0.412, -1.085, -1.198; all at P>0.05). Conclusions:Altered levels of all tested cytokines in oGVHD tears are of no significant differences between tacrolimus and cyclos porine treatment.In addition, 0.05% cyclosporine eye drops may be more comfortable than 1% tacrolimus for chronic oGVHD patients.

Objective:To evaluate the effect of modified Shengjiang Powder acupoint application on hypertension patients with phlegm-heat syndrome. Methods:A total of 61 patients in Shijiazhuang hospital of traditional chinese medicine (TCM) meeting the inclusion criteria from September 2018 to September 2019 were randomly divided into two groups, the treatment group was 30 cases, the control group was 31 cases. The control group was given Amlodipine Besylate Tablets orally, and the treatment group added modified Shengjiang Powder acupoint application, and both groups were treated for 4 weeks. TCM syndrome scores were performed before and after treatment, and 24 h ambulatory blood pressure were measured with an ambulatory blood pressure monitor, including daytime mean systolic blood pressure (dMSBP), daytime mean diastolic blood pressure (dMDBP), night time mean systolic blood pressure (nMSBP), and night time mean diastolic blood pressure (nMDBP), 24-hour mean systolic blood pressure (24 hMSBP), 24-hour mean diastolic blood pressure (24 hMDSBP) and blood pressure circadian rhythm detection. Results:After treatment, the nMSBP and 24 hMSBP in the treatment group were significantly lower than those control group ( t values were -2.331,-1.511, P values were 0.045, 0.033), the blood pressure circadian rhythm [(8.87 ± 8.33)% vs. (6.94 ± 6.12)%, t=1.034] of the treatment group was significantly higher than those of the control group ( P<0.05); mdizziness, headache, head wraps, vomiting, sputum salivation, upset, mouth pain, insomnia scores of the treatment group after treatment were significantly lower than those in the control group ( P<0.05). Conclusion:The modified Shengjiang Powder acupoint application can reduce the blood pressure level of hypertension patients with phlegm-heat syndrome, especially for the improvement of night blood pressure, and improve the clinical symptoms.

Objective To analyze the basic clinical characteristics,auxiliary diagnostic indexes,bacterial infection spectrum and drug resistance of child urinary tract infection to provide the basis for the prevention,diagnosis and treatment of child UTI.Methods The clinical data in the inpatients with UTI or complicating UTI in our hospital from January 2012 to March 2014 were collected. The repeated strains were excluded.The differences in the pathogens between the patients with complicated UTI and the patients with non-complicated UTI were comprehensively analyzed.Results The onset peak of child UTI for the first time was 0 -0.5 years old.Escherichia coli ,Klebsiella and Pseudomonas aeruginosa are the major pathogens of child UTI,in which 110 strains were Escherichia coli,accounting for 52.9%.The enterobacteriaceae pathogens of UTI had higher sensitivity to carbapenems antibacterial drugs,with the resistance rate of less than 10%;the resistance rate of others detected antibacterial drugs was more than 20%.Con-clusion UTI in the children inpatients of this area has higher drug resistance rate,in the treatment of child UTI,the antibacterial drugs should be rationally used by combining the bacterial drug resistance situation in the local place and the disease severity in or-der to avoid the aggravation of bacterial drug resistance.
