This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

Objective:To observe the clinical characteristics and guideline compliance of chronic obstructive pulmonary disease (COPD) patients with initial triple therapy in real-life world.Methods:This study is a cross-sectional study. The subjects of the study were COPD patients admitted to 13 hospitals in Hunan Province and Guangxi Zhuang Autonomous Region from December 2016 to December 2021. The initial treatment was triple inhaled drugs. The data collected included gender, age, diagnosis, body mass index (BMI), history of acute exacerbation (AE) in the past year, pulmonary function, COPD Assessment Test (CAT) score, modified British Medical Research Council Dyspnea Questionnaire (mMRC), inhaled drugs and other indicators. The characteristics and differences of COPD patients before and after 2020 were analyzed.Results:7 184 patients with COPD were enrolled in this study, including 2 409 COPD patients treated with initial triple therapy, accounting for 33.5%(2 409/7 184). Taking January 1st, 2020 as the cut-off point, 1 825 COPD patients (75.8%) received initial treatment with triple inhaled drugs before 2020 and 584 patients (24.2%) after 2020 were included in this study. Compared with COPD patients before 2020, the COPD patients after 2020 had higher FEV 1% [(40.9±15.5 )% vs (39.3±15.5)%, P=0.040], lower CAT [(15.8±6.5)point vs (17.5±6.2)point, P<0.001], less AE in the past year [1(0, 2)times vs 1(0, 2)times, P=0.001] and higher rate of non-AE [255(43.7%) vs 581(37.1%), P=0.006]. In addition, before 2020, patients with COPD were mainly treated with open triple drugs (1 825/1 825, 100%); after 2020, 306 patients (52.4%) received open triple inhaled drugs, and 278 patients (47.6%) received closed triple inhaled drugs. Conclusions:In real-life world, most of patients with COPD treated with triple therapy have severe lung function, obvious symptoms and high risk of acute exacerbation. The real-world prescribing of triple therapy in patients with COPD does not always reflect recommendations in guidelines and strategies, and overtreatment is common. After 2020, prescribing triple therapy for COPD patients is more positive and worse consistency with guideline.

Objective:To investigate the availability, prices and affordability of essential medicines in pediatric population across China, in the hope of improving rational use of medicines.Methods:A multicenter cross-sectional survey of medicine prices, availability and affordability was conducted in 17 provinces, municipalities and autonomous region across east, south-central part, west and north of China. Data on 42 medicines used in pediatric population, both original and generic, were collected in 55 public hospitals from May 26 to June 2, 2017. Availability was expressed as the percentage of hospitals with stock of the target medicine on the day of data collection,and median price ratio (MPR) was the ratio of price upon investigation to international reference. Based on national minimum daily wage, affordability represents the number of working days needed to earn the expense which covers a standard course using the target medicine. Statistical software SPSS 13.0 was applied for descriptive analysis of availability, MPR and affordability.Results:Mean Availability of original and generic medicine was 33% and 32%, with median MPR being 5.43 and 1.55. Among the 19 medicines with price information for both original and generic product, the median MPR was 7.73 and 2.04 respectively. Regarding the five medicines used to treat four common pediatric diseases (pneumonia,peptic ulcer, congenital hypothyroidism, refractory nephrotic syndrome), the affordability was 0.63 (0.16-6.17) d for generic medicine, and 1.03 (0.16-11.53) d for its original counterpart.Conclusions:The availability to both original and generic products of the 42 medicines used in pediatric population was low in China. The prices of generic medicines seem to be lower and affordability higher than those of original medicines. There is an urgent need to improve the availability and affordability of pediatric medicines.

Objective To compare the biomechanical performance of Kangli hollow screws with sliding compression locking plate system (KHS) and conventional cannulated lag screws for fixation of type Pauwels Ⅲ femoral neck fracture.Methods 7 cadaveric femurs were selected,vertical fractures (Pauwels Ⅲ fracture,at 70° to the horizontal) were artificially conducted in these cadaveric proximal femurs by an orthopaedic surgeon and fixed by KHS screws with plate system or conventional cannulated lag screws.Samples were positioned at 75° of the femoral shaft to the horizontal,embedded in the mould and fixed in the experimental console.Optical sensors were set at the femoral neck around the osteotomy line.Then the loading were input in the vertical,horizontal lateral direction and rotating direction around the femoral neck axis,the maximal and minimal values between the fractured fragments and the corresponding values of the loading were recorded.The values of stiffness in three directions were calculated and compared.The CT data of the left femur of a 25 year-old healthy male volunteer was input into the co(m)esponding software and vertical femoral neck fracture model was generated.Two finite element analysis models were obtained after the fracture being fixed using these two different implants,and the Von Mises stress distribution on the femur,implants and the interface between the fractured fragments and the relative motion between the fractured fragments were compared.Results In the vertical,horizontal lateral direction and rotating direction around the femoral neck axis,the stiffness of the KHS were 3 904±1 148 N/mm,4 324±1 234 N/mm and 11.45±4.95 N · m/° respectively,higher than those of the CSs method with the values of 3 020±1 150 N/mm,3 020± 854 N/mm.and 6.53±4.83 N· m/° respectively.The differences between the two groups were statistically significant (t=2.7194,4.7694 and 2.9424;P=0.0347,0.0050 and 0.0423).In the finite element analysis test,the maximal Von Mises stress values distributing on the femur and the screws in the KHS group were 40.1 MPa and 126.4 MPa,and those in the CSs group were 98.1 MPa and 145.5 MPa respectively,and both values of the former were lower than the latter.But the Von Mises stress value on the interface between the fractured fragments in the KHS group was 14.37 MPa,which was much higher than that in the CSs groupwhich was 9.39 MPa.The gap at the fracture site of the CSs fixation model was dramatically larger than that of KHS fixation model.Conclusion The KHS screws and plate system could provide better immobilization effect for vertical femoral neck fracture compared to the cannulated lag screws.The risk of the screws failure was lower and the fracture union would be easier to obtained by the fixation of KHS screws with plate system.

Method The rats were divided into normal group,model group and sulfotan-shinone sodium group randomly.During the experiment,acute lung injury was induced by oleic acid in rats.Sulfo-tanshinone sodium group was treated by intraperitoneal injection of sulfotanshinone sodium for 14 days consecutively. The 12 rats were sacrificed at 7thand 14thday after last administration.The indexes of weight,arterial partial pres-sure of oxygen(PaO2),oxygenation index(PaO2/FiO2),lung index and wet/dry ratio,IL-1,TNF-α,PCⅢ,TGF-β1 and the lung histopathology of rats were observed. Results There was no difference in rat weight between the groups.The values of PaO2and PaO2/FiO2were increased.The lung index and wet/dry ratio,IL-1,TNF-α,PCⅢ, TGF-β1 and IQA were all reduced. The lung histopathology damage was significantly lightened.as compared with the model group. Conclusion It has treatment effect of sulfotanshinone sodium in lung fibrosis in the ALI rats, which may be related with the adjustment on inflammatory factor.

Objective To explore the effects of tutor psychological counseling on adaptation in freshmen of university. Methods From September 2015 to September 2016, we selected 212 five-year undergraduate freshmen majored in clinical medicine from two classes of 2015 in Hubei University of Medicine as subjects by convenience sampling. Students of class 1 of clinical medicine were set as the experimental group (n=105). Students of class 2 of clinical medicine were set as the control group (n=107). Students of control group were taught according to conventional methods. Otherwise, students of the experimental group accepted targeted psychological counseling by instructors assisted by tutor. All of the students were evaluated with the China College Student Adjustment Scale (CCSAS) when they enrolled and one year after they enrolled. Results After implementing psychological counseling, the scores of 7 dimensions of CCSAS including interpersonal relationship, learning adaptation, campus adaptation, occupational selection, emotion, self-adaptation, satisfaction of students of the experimental group were (35.87±4.528), (45.10±7.682), (29.21±4.243), (33.02±4.290), (29.84±5.000), (29.07±5.432), (18.75±3.419) higher than those [(33.66±5.234), (37.91±8.280), (25.84±4.685), (28.79±3.683), (27.13±4.535), (25.21±4.455), (17.15±3.618)]of the control group with significant differences (t=-3.275, -6.559, -5.422, -7.698, -4.131, -5.650, -3.314; P<0.01).
