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.

With the spread of novel coronavirus pneumonia (NCP) in December 2019, the management and rehabilitation of elderly patients with hip fractures and protection of medical staff face new challenges, and need to be adjusted appropriately under this very circumstances. Hip fractures in the elderly account for more than half of osteoporotic fractures. Expert group formulate this consensus so as to make better decision against this epidemic and protect patients' families and medical staff. This consensus elaborates not only epidemic condition of NCP, but also general principles of medical admission, treatment and protection for both medical staff and patients, in order to provide some reference and promote the standardization of clinical diagnosis and treatment of elderly patients with hip fractures under the condition of NCP.

TSCI have dyskinesia and sensory disturbance that can cause various life-threaten complications. The patients with traumatic spinal cord injury (TSCI), seriously affecting the quality of life of patients.

OBJECTIVE： To investigate the characteristics and regularity of hepatotoxicity induced by quinolones， and to provide reference for clinical use of drug safely. METHODS： Using “quinolone” “floxacin” “hepatotoxicity” “hepatic injury”as retrieval words， relevant literatures about hepatotoxicity induced by quinolones were retrieved from domestic and foreign databases as CNKI， Wanfang， VIP， PubMed （during database establishment to 31th， Dec. 2017）. Those literatures were summarized and analyzed. RESULTS： A total of 59 valid literatures were collected， including 61 cases of hepatotoxicity induced by quinolones， 8 types of drugs as ciprofloxacin， moxifloxacin， ofloxacin， lomefloxacin， norfloxacin， levofloxacin， gatifloxacin and enoxacin. Ciprofloxacin， levofloxacin， moxifloxacin and ofloxacin were the most common drugs that caused hepatotoxicity， involving 19， 13， 11， 7 cases， respectively； accumulative constitute ratio was 81.97％. The ratio of male to female was 1.54 ∶ 1， and hepatotoxicity always happened at the age of 61 to 80 （30 cases， 49.18％）. Primary diseases of 46 cases were single disease （75.41％）， and mainly were infection of respiratory system and urogenital system. There were 15 cases of combined disease （24.59％）. Thirty-one cases used quinolones alone， most of which was ciprofloxacin. There were 30 cases of drug combination. Thirty-four cases were given drug intravenously and mainly were domestic cases. The hepatotoxicity first occurred within 10 minutes after administration and at the latest 8 weeks after administration. Forty-nine patients suffered from hepatotoxicity within 10 days after medication， accounting for 80.33％. Besides general fatigue， nausea and vomiting， clinical symptoms also included abnormal elevation of alanine aminotransferase， aspartate aminotransferase and total bilirubin，etc. Fifty-four patients were improved after withdrawal or symptomatic treatment， while 7 patients died. The results of causality evaluation of drug-induced hepatic injury showed that there were 4 probably association cases， 45 likely association cases and 12 possible association cases. CONCLUSIONS： The hepatotoxicity caused by quinolones is related to drug variety， patient’s age， primary disease， drug combination and route of administration， and mostly occurs within 10 days after administration. Great importance should be attached to patient’s liver function indexes， strengthen medication monitoring， and carefully combined use of drugs.

Objective: To explore the clinical effects of antibiotic bone cement in the treatment of diabetic foot ulcers. Methods: According to the treatment methods, 18 patients with diabetic foot ulcers (11 males and 7 females, aged 53-79 years), who were conformed to the study criteria and admitted to our hospital from January 2016 to January 2017, were enrolled in traditional group; 18 patients with diabetic foot ulcers (11 males and 7 females, aged 55-80 years), who were conformed to the study criteria and admitted to our hospital from February 2017 to February 2018, were enrolled in bone cement group. Wounds of patients in traditional group were treated with vacuum sealing drainage after conventional debridement. Wounds of patients in bone cement group were covered with antibiotic bone cement after conventional debridement. The number of patients with positive bacterial culture in wound exudate in the 2 groups on admission and 3, 6, 9, and 15 days after surgery, the length of hospital stay, the number of operation, and the wound complete healing time were retrospectively recorded. Data were processed with Fisher′s exact probability test and independent sample t test. Results: Compared with (29±10) d and (4.6±1.2) times of patients in traditional group, the length of hospital stay [(9±3) d] of patients was obviously shortened, the number of operation [(1.3±0.6) times] of patients was obviously reduced, the number of patients with positive bacterial culture in wound exudate at each time point post surgery was obviously reduced (t=8.177, 9.896, P<0.05 or P<0.01) in bone cement group. There were no statistically significant differences in the number of patients with positive bacterial culture in wound exudate on admission and wound complete healing time between patients in the 2 groups (t=0.175, P>0.05). Conclusions The antibiotic bone cement treatment of diabetic foot ulcers can reduce the number of patients with positive bacterial culture in wound exudate and the number of operation, as well as shorten the length of hospital stay.

Objective: To compare the pharmacokinetics and bioavailability of pirfenidone in the fasted and fed states in healthy volunteers. Methods: An open-label, randomized crossover study was conducted in 12 healthy subjects. Food effects were examined by comparing pharmacokinetic data of pirfenidone after administration of a single oral 400 mg dose under fasted or fed conditions. Plas-ma pirfenidone concentration was determined by an HPLC method and its pharmacokinetic parameters were calculated with DAS v2. 0 software. Results: Under fasted and fed conditions, the concentration-time profiles of pirfenidone were fitted a one-compartment model and the pharmacokinetic parameters were as follows: t1/2were (2. 16 ± 0. 47) and (2. 05 ± 0. 42) h;tmaxwere(0. 69 ± 0. 16)and (1. 46 ± 0. 40)h;Cmaxwere (12. 95 ± 1. 79) and (9. 16 ± 2. 87) mg·L-1;AUC0-12were (44. 97 ± 15. 06) and (36. 19 ± 14. 44) mg·h·L-1;AUC0-∞were (46. 55 ± 16. 79) and (37. 41 ± 15. 43) mg·h·L-1, respectively. When compared with that of the fasted group, tmaxwas significantly increased (P<0. 001) while Cmaxand AUC were remarkedly decreased in the fed group (P<0. 001 and P<0. 01, respectively). Conclusion: Concomitant food intake significantly influences the pharmacokinetics and bioavail-ability of pirfenidone as indicated by reducing its extent and rate of absorption, which is associated with better tolerability.

Objective:To investigate the clinical characteristics and causes of serotonin syndrome induced by tramadol in order to provide references for rational drug use in clinical practice. Methods:The relevant literatures published in domestic medical journals from the building of database to 2016 were retrieved in PubMed, EMbase, CNKI and WanFang database and statistically analyzed in respects of types and relevance evaluation of adverse drug reactions, the age and gender distribution of patients, the application of drugs,occurrence time of serotonin syndrome,clinical manifestations,treatment and outcome. Results:A total of 21 cases of seroto-nin syndrome induced by tramadol were collected. Totally 19 cases were caused by combined drug use, among which 12 cases were combined with selective serotonin reuptake inhibitors. The results of relevance evaluation showed 19 cases of possible relevance and 2 cases of probable relevance. Totally 10 cases of severe adverse drug reactions were reported and 11 cases of common adverse drug reac-tions were exhibited. One patient was heterozygous for CYP2D6 polymorphisms(CYP2D6?1/?4) causing decreased metabolizing a-bility to tramadol. Totally 28.6% of patients developed symptoms in 24h after the addition of new serotonergic agents or increase the dosage of serotonergic agents. In most cases,the patients' syndrome resolved with discontinuation of at least one serotonergic drug and symptomatic treatment,usually in less than one week. Conclusion:When prescribing tramadol,physicians should be aware of seroto-nin syndrome induced by drug-drug interactions and possible pharmacogenetic factors. It is important that safety monitoring should be carried out in patients during the application of drugs to reduce the harm of adverse drug reactions.
