Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To observe the effect of omeprazole enteric-coated capsules on clinical symptoms and serum inflammatory factor levels in children with chronic gastritis and peptic ulcer.Methods Children with chronic gastritis and peptic ulcer were divided into treatment group and control group by random number table method.The control group was given triple therapy of ranitidine hydrochloride tablets,amoxicillin and clarithromycin,while the treatment group was treated with omeprazole enteric-coated capsules combined with amoxicillin and clarithromycin.Clinical efficacy,symptom relief time,and changes in serum motilin(MOT),gastrin(GAS)and inflammatory factors[interlrukin-6(IL-6)and interlrukin-8(IL-8)]were compared between the two groups.Results There were 48 cases in treatment group and 48 cases in control group.After treatment,the total effective rates in treatment group and control group were 93.74％(45 cases/48 cases)and 85.42％(41 cases/48 cases),with significant difference(P＜0.05).After treatment,the disappearance time of ulcer induced pain in treatment group and control group were(1.51±0.26)and(2.08±0.42)d;the disappearance time of acid regurgitation were(2.29±0.40)and(2.93±0.33)d;the disappearance time of burning sensation were(2.37±0.21)and(2.85±0.54)d;the length of hospital stay were(6.21±1.07)and(6.94±1.25)d;serum MOT levels were(298.48±35.15)and(273.58±31.25)pg·mL-1;serum GAS levels were(167.28±19.46)and(128.32±18.61)ng·L-1;IL-6 levels were(58.67±5.39)and(76.14±6.63)mg·mL-1;IL-8 levels were(50.08±5.16)and(58.68±5.49)mg·mL-1.The above indexes were significantly different between control group and treatment group(all P＜0.05).The total incidence of adverse drug reactions in treatment group and control group were 8.33％and 12.50％,with no statistical significance(P＞0.05).Conclusion Omeprazole enteric-coated capsules in the treatment of children with chronic gastritis and peptic ulcer can effectively alleviate various clinical symptoms and improve clinical efficacy.At the same time,it can lower serum levels of inflammatory factors and improve inflammation,with good effect.

Objective To explore the role of Panax notoginseng saponins(PNS)in regulating the expression of sortilin and ATP-binding cassette transporter A1(ABCA1)in macrophages,and the effect of PNS on inhibiting formation of foam cells and the potential mechanism of PNS adjusting sortilin expression and cholesterol metabolism.Methods The macrophages were divided into five groups as follows:group A(only added with cell culture),group B(transfected with negative control lentivirus),group C(transfected with lentivirus-mediated sortilin overexpression),group D(transfected with lentivirus-mediated sortilin overexpression+60 μg·mL-1PNS),group E(transfected with lentivirus-mediated sortilin overexpression+10 μmol·L-1 mitogen-activated protein kinase kinase(MEK)inhibitor PD98059+60 μg·mL-1 PNS).The protein contents of sortilin,ABCA1,extracellular signal-regulated kinase(ERK)and phosphorylated-ERK(p-ERK)were evaluated with Western blot.All the cells in five groups were cultured with 50 μg·mL-1ox-LDL to form foam cells.The lipid in macrophages was investigated with red O assay.Results The relative expression levels of sortilin protein were 1.00±0.08,0.91±0.15,2.28±0.13,1.62±0.09 and 2.01±0.08;the relative expression levels of ABCA1 protein were 1.00±0.01,0.92±0.07,0.29±0.04,0.66±0.09 and 0.44±0.07;the ratios of p-ERK/ERK protein were 1.00±0.09,0.92±0.05,1.03±0.12,2.00±0.12 and 1.64±0.14;the contents of lipid in macrophages were(4.82±2.19)％,(6.70±0.88)％,(44.56±4.15)％,(27.66±3.25)％and(41.67±5.45)％.Except the ratios of p-ERK/ERK,the other parameters between group C and group A were statistically significant difference(all P＜0.01).Meanwhile,there were also statistically significant difference between group D and group C as well as group D and group E(P＜0.05,P＜0.01).Conclusion PNS inhibits the lipid accumulation in macrophages through upregulating ABCA1 and downregulating sortilin,and ERK signaling pathway may be as one of important mechanisms influencing the expression of sortilin and ABCA1 mediated by PNS.

The seminal vesicle is an important accessory gland of the male reproductive system.In the past,some scholars fo-cused more on its role in the fertilization process and neglected its relationship with male sexual function.Researches show that the se-minal vesicle is involved in multiple processes such as sexual desire,penile erection,and ejaculation.Treatment of sexual dysfunction by medication targeting the seminal vesicle has achieved certain therapeutic effects.This article discusses the relationship between the seminal vesicle and sexual function in terms of physiopathology,clinical study and basic research,hoping to provide some new ideas on the clinical diagnosis and treatment of sexual dysfunction.

Chronic nonbacterial prostatitis(CNP)is one of the most common diseases in urology and andrology,with a complex etiology and a high incidence rate.Traditional Chinese medicine plays an important role in the treatment of CNP and can produce thera-peutic effects through various action mechanisms.This article presents an overview of recent studies on the specific mechanisms of tra-ditional Chinese medicine acting on CNP,including the mechanisms underlying its effects of anti-infection,anti-inflammation,immune regulation,improvement of urodynamics,endocrine regulation,improvement of microcirculation,and regulation of gut microbiota,ai-ming to provide some reference for the clinical application and basic studies of traditional Chinese medicine in the treatment of CNP.

Ferroptosis is a form of cell death resulting from the disruption of iron metabolism within cells and excessive accumu-lation of lipid peroxides.Research indicates that,under the influence of various pathogenic factors,ferroptosis impacts the male repro-ductive system and fertility by affecting the synthesis of testicular hormones and regulation of cellular functions through different path-ways and numerators.This paper provides an overview of the action mechanisms of ferroptosis in the testis and its correlation with path-ogenicity,offering some new insights into the treatment of male reproductive system diseases.

Objective To explore the clinical characteristics of impulse control disorders(ICD)and related influencing factors in patients with cerebral hepatolenticular degeneration(HLD).Methods Eighty-nine patients with cerebral HLD who were hospitalized in the Brain Disease Center of the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine(AUTCM)from April 2023 to October 2023 were randomly collected and divided into the ICD group and the control group based on the Minnesota Impulsivity Disorder Interview(MIDI)scale,which assessed the patients'neurological function(UWDRS-Ⅰ),hepatic function(UWDRS-Ⅱ),cognition(MMSE),sleep(PSQI),anxiety(HAMA-14),depression(HAMD-17),and adherence to medications taken(MMAS-8);and univariate and multivariate forward stepwise Logistic regression models were used to screen the influencing factors related to ICD in patients with cerebral HLD.Results ICD were present in 44 patients,of which a higher proportion showed stereotyped behaviors and compulsive shopping.UWDRS-Ⅰ,UWDRS-Ⅱ,PSQI,HAMD and HAMA scores were higher in the ICD group than in the control group(P＜0.05).MMSE scores were lower in the ICD group than in the control group(P＜0.05).The ICD group had a younger age of onset and a longer disease duration than the control group(P＜0.05).The two groups were significantly different in terms of education level and smoking history(P＜0.05).Logistic regression analysis showed that a high level of education was a protective factor for the occurrence of ICD in patients with cerebral HLD(P＜0.05),and a high UWDRS-Ⅰ score was an independent risk factor for the occurrence of ICD(P＜0.05).Conclusion ICD in patients with cerebral HLD manifested as stereotypical behaviors and a higher percentage of compulsive shopping,the proportion of anxiety,depression,cognitive disorders,and sleep disorders was significantly higher among patients with ICD.Patients with cerebral HLD with a low level of education and severe neurological symptoms were more likely to develop ICD.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.
