This article systematically analyzes the historical evolution of the name， origin， medicinal parts， processing and other aspects of Euphorbiae Pekinensis Radix（EPR） by referring to the herbal medicine， medical books， prescription books and other documents of the past dynasties， combined with the relevant modern research materials， so as to provide a basis for the development and utilization of famous classical formulas containing this herbal medicine. According to research， EPR was first recorded in the Shennong Bencaojing in the name of Daji， and it is the correct name of the herbal medicine in all dynasties， there are also other aliases such as Qiongju， Hongya Daji， and Xiamaxian. The dried roots of Euphorbia pekinensis from Euphorbiaceae was the mainstream of the past dynasties. Before the Ming dynasty， the above ground parts of E. pekinensis were used as Zeqi in herbal works. However， since LI Shizhen in the Ming dynasty proposed that the origin of Zeqi should be E. helioscopia， the aerial part of EPR is no longer used as medicine. Since modern times， the roots of Knoxia valerianoides has been used as EPR， and has become the mainstream of commodities， which should be corrected. Throughout history， it has been recorded that the main producing areas were Jiangsu， Anhui， Zhejiang， Shanxi and other regions， while modern botanical survey have shown that EPR is a widespread species distributed throughout the country. In ancient times， the harvesting time of EPR was mostly the twelfth lunar month， while in modern time， it is more common to harvest in autumn and winter. The main processing methods of EPR in ancient times were vinegar processing， wine processing， and stir frying， while in modern times， it is uniformly vinegar processing. In the medicinal properties and clinical aspects， the records are basically consistent throughout history， mainly characterized by bitter taste， cold and toxic nature. Its main efficacy is expelling water retention and reducing swelling. Based on the textual research， it is suggested to choose the dried roots of E. pekinensis when famous classical formulas containing EPR， processing method can be based on the original specified prescription requirements， if the processing method is not clear， it is recommended to use vinegar-processed products as medicine.

Objective:To investigate the distribution characteristics of urinary tract pathogens in patients with community-acquired urinary tract infection and their sensitivity to nenoxacin and levofloxacin.Methods:This prospective, multicenter clinical trial included patients with community-acquired urinary tract infection who were admitted to urological clinics at 9 clinical research centers from November 2021 to August 2022.Inclusion criteria: Patients aged 18-70 years with community-acquired acute uncomplicated cystitis(AUC), recurrent acute episodes of urinary tract infection(rUTI), and non-febrile complicated urinary tract infection(cUTI) with signs of urinary tract irritation and abnormal elevation of routine white blood cells in urine. Exclusion criteria: ①Patients who received effective antimicrobial therapy within 72 h before enrollment and lasted for more than 24 h. ②Fever (>37.3℃) or symptoms of upper urinary tract infection such as low back pain, tapping pain in the kidney area, etc. ③Indwelling urinary catheter. At the first visit, clean midstream urine samples were taken for bacterial culture, and the distribution characteristics of urinary pathogens of different types of urinary tract infections were analyzed. Extended spectrum β-lactamases (ESBLs) were measured for Gram-negative bacteria. The susceptibility of nenoxacin and levofloxacin to urinary tract pathogens was determined by disk diffusion method. Drug resistance rate, sensitivity rate were analyzed between different disease groups.Results:There were 404 enrolled patients from 9 hospitals, including 364 (90.1%) females and 40 (9.9%) males. A total of 177 strains of pathogenic bacteria were isolated, among which the highest proportion of Escherichia coli was 66.1% (117/177).Klebsiella pneumoniae was followed by 6.8% (12/177) and Streptococcus agalactis 5.1% (9/177). The bacterial spectrum distribution of AUC and rUTI were similar, and the proportions of Escherichia coli were 70.6% (85/119) and 65.9% (29/44), respectively. However, the proportions of Escherichia coli isolated from cUTI patients were only 28.6% (4/14) and Enterococcus faecalis 7.1%(1/14). The overall detection rate of ESBLs in Gram-negative bacteria was 30.9%(43/139). The sensitivity rate of nenoxacin was 74.6%(91/122), and the resistance rate was 25.4%(31/122). The overall sensitivity rate of levofloxacin was 44.9%(70/156) and the resistance rate was 36.5%(57/156). The rate of resistance of urinary tract pathogens to levofloxacin was 48.2% (27/56) in patients with previous urinary tract infection history, and 30.0% (30/100) in patients with no previous urinary tract infection history, the difference was statistically significant( P=0.023).The sensitivity rate of Gram-negative bacteria to nenofloxacin was 70.7% (65/92) and that to levofloxacin was 50.0% (46/92, P<0.001). The sensitivity of Gram-positive bacteria to nenofloxacin was 80.0% (16/20), and that to levofloxacin was 70.0% (14/20, P=0.009). Conclusions:The bacterial profile of out-patient community acquired urinary tract infection varies greatly according to different diseases. The proportion of Escherichia coli in AUC and rUTI patients is higher than that in cUTI. The detection rate of ESBLs in Gram-negative bacteria was lower than the domestic average.Patients with a history of urinary tract infection had a high risk of treatment failure with levofloxacin. The sensitivity of common urinary tract pathogens to nenofloxacin was higher than levofloxacin.

Objective To understand the current situation of human brain donation in Hebei Province by analyzing the basic information of Human Brain Bank samples of Hebei Medical University in order to provide basic data support for subsequent scientific research.Methods The samples collected from the Human Brain Bank of Hebei Medical University were analyzed(from December 2019 to February 2024),including gender,age,cause of death,as well as quality control data such as postmortem delay time,pH value of cerebrospinal fluid and and RNA integrity number and result of neuropathological diagnosis.Results Until February 2024,30 human brain samples were collected and stored in the Human Brain Bank of Hebei Medical University,with a male to female ratio of 9∶1.Donors over 70 years old accounted for 53％.Cardiovascular and cerebrovascular diseases(36.67％)and nervous system diseases(23.33％)accounted for a high proportion of the death causes.The location of brain tissue donors in Shijiazhuang accounted for 90％donations,and the others were from outside the city.The postmortem delay time was relatively short,90％within 12 hours and 10％more than 12 hours.69.23％of the brain samples had RNA integrity values greater than 6.Cerebrospinal fluid pH values ranged from 5.8 to 7.5,with an average value of 6.60±0.45.Brain weights ranged from 906-1496 g,with an average value of(1210.78±197.84)g.Three apolipoprotein E(APOE)alleles were detected including five genotypes(ε2/ε3,ε2/ε4,ε3/ε3,ε3/ε4,ε4/ε4).Eleven staining methods related to neuropathological diagnosis had been established and used.A total of 12 cases were diagnosed as neurodegenerative diseases(including Alzheimer's disease,Parkinson's disease,multiple system atrophy,corticobasal degeneration and progressive supranuclear palsy,etc.),accounting for 40％donated brains.The comorbidity rate of samples over 80 years old was 100％.Conclusion The summary and analyses of the data of brain donors in the Human Brain Bank of Hebei Medical University can reflect the current situation of the construction and operation of the brain bank in Hebei Province,and it can also be more targeted to understand and identify potential donors.Our information can provide reference for the construction of brain bank and provides more reliable materials and data support for scientific research.

The pathogenesis of the nephrotic syndrome is complex and the pathological types are diverse, so the minor symptoms in its early phases are difficult to detect. Renal biopsy is the gold indicator for the diagnosis of renal pathology and progression, but poor patient compliance shows, and the optimal treatment time is often delayed. Therefore, the discovery of biomarkers for early diagnosis and disease progression monitoring is of great clinical significance. In this study, doxorubicin-injured podocyte models were used to simulate human kidney disease at different stages of progression. LC-MS-based metabolomic technology combined with statistical methods was used to screen and identify the potential biomarkers associated with early injury or progression of podocytes. The results of cell viability, apoptosis tests and podocyte structural protein analysis showed that the model was successfully constructed, and the degree of podocyte injury was significantly different between the two modeling methods. According to VIP > 1 and P < 0.05 based on the orthogonal partial least squares discriminant analysis (OPLS-DA) model, nine differential metabolites reflecting early podocyte injury and twelve differential metabolites reflecting the injury progression were screened, respectively. ROC analysis was adopted to focus on the potential biomarkers that can reflecting the early podocyte injury including L-tryptophan, guanosine triphosphate (GTP), 5′-thymidylic acid (dTMP) and thymidine, and the biomarkers reflecting the injury progression of podocytes composed of L-phenylalanine, L-tyrosine acid, uridine 5′-diphosphate (UDP) and guanosine 5′-diphosphate (GDP) AUC > 0.85. It indicated that these eight metabolites may have high sensitivity and diagnostic ability. This study provides a reference for the research on biomarkers of progressive diseases.

Objective To describe the research hotspots and authors'cooperative relationships in the field of pharmacoepidemiology mentioned in the 2022 International Conference on Pharmacoepidemiology and Therapeutic Risk Management(ICPE),and compare with those result of ICPE 2021.Methods Taking the 2021-2022 ICPE abstracts as the data source,we used Python to extract literature information.R software networkD3 package was used to draw network diagrams of cooperative relationships among authors and organizations.Term frequency-inverse document frequency technology in tidytext package was used to conduct weighted statistics on the frequency of tokens to identify hotspot diseases,drugs,databases,etc.Results 2 086 ICPE abstracts were included.Between 2021 and 2022,the number of abstracts,authors,and organizations increased by 58.8%,42.3%,and 24.9%respectively.In 2022,there were a total of 387 core authors(including 14 from China,all from Hong Kong and Taiwan district),forming 26 close cooperation groups(including 2 Chinese groups).161 core organizations(including 8 in China),constituted 18 close cooperation groups(including 1 Chinese-foreign group and 1 Chinese domestic group).The topic of COVID-19,type 2 diabetes,and rheumatoid arthritis have always been deeply discussed,meanwhile,the discussion popularity of breast cancer,Parkinson's disease and dementia have increased significantly.Opioids,sodium-glucose transporters 2 inhibitors,and antipsychotics have always been popular drugs,and the popularity of antidepressants,COVID-19 vaccines and antihypertensive drugs have increased markedly.The hotspot databases included Clinical Practice Research Datalink,IBM MarketScan Commercial Claims and Encounters,and Food and Drug Administration Adverse Event Reporting System,etc.Conclusion From 2021 to 2022,the scale of ICPE has expanded,and academic cooperation has become more extensive and in-depth.However,there is still a big gap between the participation and cooperation scale of scholars from Chinese mainland and foreign countries.Breast cancer,Parkinson's disease,dementia,antidepressants,and COVID-19 vaccines are new hot topics at ICPE 2022.The research hotspots and cooperation networks displayed in this article have certain reference values for Chinese pharmacoepidemiologists in selecting future research topics and partners.

OBJECTIVE: To compare the safety of low-dose cyclophosphamide and high-dose cyclophosphamide in the treatment of systemic lupus erythematosus (SLE). METHODS: A total of 1 022 patients with systemic lupus erythematosus from 24 hospitals in China between March 2017 to July 2018 were enrolled. Their clinical manifestations, laboratory tests, adverse events, reasons for stopping receiving intravenous cyclophosphamide and comorbidities were collected. Among them, 506 SLE patients received short-interval low-dose intravenous cyclophosphamide therapy (SILD IV-CYC, 400 mg every two weeks), and 256 patients underwent high-dose cyclophosphamide therapy (HD IV-CYC, 500 mg/m² of body surface area every month), the side effects between the two groups were compared, the remaining 260 SLE patients were treated with IV-CYC irregularly. Moreover, a total of 377 patients in SILD IV-CYC group and 214 patients in HD IV-CYC group had medical records of the reasons for stopping recei-ving IV-CYC. The reasons for stopping receiving IV-CYC in these two groups were analyzed. RESULTS: In this study, only 40.27%(238/591)of the SLE patients stopped receiving intravenous cyclophosphamide for the causes of disease improvement, however, up to 33.67% (199/591) of the patients for the reason of drug-related side effects. There were 83 patients out of 214 (38.79%) with high-dose intravenous cyclophosphamide treatment who stopped receiving IV-CYC for the drug-related side effects, which was significantly higher than that in the low-dose cyclophosphamide group (30.77%, 116/337, P=0.048). Of theses 506 patients in SILD IV-CYC group, 88 (17.39%) patients experienced gastrointestinal reactions, 66 (13.04%) suffered from infections, 49 (9.68%) had myelosuppression and 68 (13.44%) had alopecia, respectively. Among the 256 patients in the HD IV-CYC group, 80 (31.25%) experienced gastrointestinal reactions, 57 (22.27%) suffered from infections, 51 (19.92%) had myelosuppression and 49 (19.14%) had alopecia. Moreover, 71 (25.18%) of 282 female patients with age between 16 to 45 years in SILD IV-CYC group had abnormal menstruation, while menstrual disorder occurred in 39.72% (56/141) patients of HD IV-CYC group. There was no difference of drug-induced hepatic injury, hemorrhagic cystitis and fatigue between the two groups. CONCLUSION Low-dose cyclophosphamide showed a lower prevalence of adverse events than high-dose cyclophosphamide in systemic lupus erythematosus patients.

OBJECTIVE: To develop a new classification of acromion based on the subacromial impingement theory and the Rockwood tilt view. And explore the application value of the new classification in the diagnosis and treatment of rotator cuff tear. METHODS: The clinical data of 101 patients underwent shoulder arthroscopic surgery for impingement syndrome or rotator cuff tear from January to December 2017 were retrospectively analyzed. There were 34 males and 67 females, aged from 34 to 76 years with an average of (56.31±9.63) years old, course of disease from 2 to 12 months with average of 6 months. Preoperative radiographs of the routine anteroposterior view, Rockwood tilt view and the supraspinatus outlet view were obtained. Based on the subacromial impingement theory and Rockwood radiographs, the morphology of the acromion can be divided into three types:typeⅠ(flat type), typeⅡ(bump type), and type Ⅲ (impingement type). Two observers classified 101 shoulder Rockwood radiographs according to the new classification method and the supraspinatus Outlet radiographs according to the traditional acromial morphological classification method. Supraspinatus tendon injuries were classified into no tear, partial-thickness tear, and full-thickness tear according to the arthroscopic findings. Concordance test (Kappa value) between the inter-observer and intra-observer was carried out for the new classification method and the traditional classification method respectively. The rank sum test was used to compare the mean acromiohumeral distance(AHD) of the three acromion forms in the new acromion classification method. Spearman rank correlation test and Gamma method were used to analyze the correlation between the new acromion classification method and the degree of supraspinatus tendon tear. RESULTS: The inter-observer consistency analysis of the new classification system was significantly better than that of the traditional classification (0.827 vs 0.278), the intra-observer consistency analysis of the new classification system were also significantly better than that of the traditional classification (0.921 vs 0.448, 0.890 vs 0.539). There was no statistical significance in the AHD among three types of the new classification(H=2.186, P>0.05). In all 101 patients, the highest proportion of impingement type acromion was 45.5% (46 cases), followed by bump type acromion was 36.6% (37 cases), and flat type acromion was 17.8% (18 cases). The incidence of supraspinatus tendon tear in the patients with impingement type acromion was significantly higher than that of the other two types of acromion, there was a spearman rank correlation between the new acromion type and the degree of the supraspinatus tendon tear(rs=0.719, P<0.001). CONCLUSION Rockwood radiographs of the shoulder can well display the anterolateral osteophytes of the acromion. The new acromion classification method based on Rockwood radiographs has high reliability and good reproducibility, in which impingement type of acromion is closely related to supraspinatus tendon tear. Compared with the traditional classification and AHD, the new classification method has more diagnostic value than for rotator cuff injury.

Objective: To investigate the occupational hazard factors and exposure levels of workers during the construction of power transmission and transformation projects. Methods: Analysis and identification of occupational hazard factors were carried out for typical construction process of 6 power transmission projects and 3 substation projects in September 2018. The on-site occupational health investigation was carried out to detect and analyze the exposure levels of workers to occupational hazard factors. Results: The time weighted average concentration (C(TWA)) of crushing workers exposed to silica dust and welders exposed to welding fume in substation projects were 2.72 and 14.03 mg/m(3), respectively. The 8 h equivalent sound level results of exposure noise of carpenters in power transmission projects and crushing workers, reinforcement workers, carpenters, scaffolders, road builders in substation projects were 87.9, 92.5, 87.1, 92.5, 93.0 and 90.2 dB (A) , respectively. The 4-hour time equal energy frequency weighted vibration acceleration of hand-transmitted vibration of bricklayer in power transmission projects, bricklayer, general worker 3, road builder 1 and road builder 2 of substation projects were 5.36, 5.21, 5.28, 10.71 and 5.22 m/s(2), respectively. The effective irradiance of electric welding arc light of welders' limbs in power transmission projects and substation projects were 401.19, 319.68 μW/cm(2), respectively. All of the above exceeded the requirements of occupational exposure limits. The occupational radiation levels and exposure limits of hazardous chemical factors met the requirements of each post. Conclusion: During the construction of power transmission and transformation projects, the exposure levels of occupational hazard factors in multiple posts exceed the standard. The main responsibility of employers for occupational disease prevention and control should be implemented, and targeted comprehensive measures should be taken to reduce the exposure levels of occupational hazard factors of workers.

Objective: To investigate the safety and feasibility of caudal-medial approach combined with "page-turning" middle lymphadenectomy in the laparoscopic right hemicolectomy. Methods: A descriptive cohort study was conducted. Clinical data of 35 patients who underwent laparoscopic radical right hemicolectomy using caudal-medial approach combined with "page-turning" middle lymphadenectomy at Department of Gastrointestinal Surgery, Guangdong Hospital of Chinese Medicine from April 2018 to May 2020 were retrospectively analyzed. All operations were performed consecutively by the same surgeon. The caudal-medial approach was used to dissect the right Toldt's fascia and the anterior pancreaticoduodenal space in a caudal-to-cranial and medial-to-lateral manner guided by the duodenum. The "page-turning" middle lymphadenectomy was used to dissect the mesocolon along the superior mesenteric vein with ileocolic vein, Henle's trunk and pancreas exposed preferentially. Results: All the 35 patients completed the operation successfully, and there was no damage and bleeding of superior mesenteric vessels and their branches. The operative time was (186.9±46.2) minutes, and the blood loss was 50 (10-200) ml. The first time to flatus was (2.1±0.6) days, and the time to fluid intake was (2.5±0.8) days. The postoperative hospital stay was 6 (3-18) d. The overall morbidity of postoperative complication was 8.6% (3/35), including grade II in 1 cases (2.8%) and grade IIIa in 2 case (5.7%) according to the Clavien-Dindo grading standard. The total number of lymph node dissected was 30.2±5.6, and the positive lymph node was 0 (0-7). Tumor staging revealed 5 cases of stage I, 18 cases of stage II, 11 cases of stage III, and 1 case of stage IVA. In this study, the median follow-up time was 15 (4-29) months. One patient died due to cerebrovascular accident 12 months after surgery, and no tumor recurrence or metastasis was observed in all other patients. Conclusions: Laparoscopic radical right hemicolectomy using caudal-medial approach combined with "page-turning" middle lymphadenectomy is safe and feasible. The anterior pancreaticoduodenal space is preferentially mobilized, which reduces the difficulty of central vascular dissection.
