OBJECTIVE To formulate Guidelines for the standardized implementation of pharmacist-managed clinics （ 2026 edition ） in response to the challenges faced by such clinics in China， including uneven development， large discrepancies in service specifications， insufficient patient awareness， and limited medical insurance coverage. METHODS Led by the Pharmaceutical Affairs Professional Committee of the Chinese Hospital Association， the Evidence-based Pharmacy Professional Committee of the Chinese Pharmaceutical Association， and the Hospital Pharmacy Professional Committee of the Cross-strait Medical and Health Exchange Association， a total of 19 domestic hospital pharmacy experts were organized. Through a systematic review of national policies and literature research， current practical experience was summarized. Consensus on the contents of the guidelines was reached after in-depth discussions. RESULTS &CONCLUSIONS The guidelines covered five sections： definition and connotation of pharmacist-managed clinics， establishment requirements， implementation and management， post competency， and practical research. Firstly， the definition and connotation included three operational forms of pharmacist-managed clinics （independent mode， physician-pharmacist joint mode， and online pharmacist-managed clinic mode） and classified service modes （specialty-specific， drug-specific， and disease-specific pharmacist-managed clinics）. The establishment requirements were further refined， covering system construction （pharmaceutical service management system， quality control and assessment mechanism）， personnel qualifications （professional credentials， continuing education and professional training， etc）， service recipients， as well as service venues and facilities. Subsequently， the implementation and management of pharmacist-managed clinics were proposed， involving service procedures， intervention measures， documentation and records， patient education and follow-up， humanistic care， as well as risk management and quality control. Finally， post competency encompassed the competency requirements for pharmacists providing services in pharmacist-managed clinics， as well as the suggestions on teaching methods； practical research encouraged the conduct of high-quality pharmaceutical practice in the setting of pharmacist-managed clinics. The guidelines provide valuable guidance for the standardized implementation of pharmacist-managed clinics in China in terms of establishment， management， teaching， and research， fill the guideline gap in this field， and can promote the high-quality development of pharmacist-managed clinics.

As the most abundant and essential structural protein in the human body, collagen is ubiquitously present in the interstitium of nearly all solid organs, playing a crucial role in maintaining the structural integrity and functional stability of human tissues and organs. Disorders associated with collagen structure and metabolisms impose a significant burden on society and healthcare systems. Post-translational modifications (PTMs) are essential steps in collagen metabolism, and recent studies have indicated that aberrant regulation of PTMs plays a pivotal role in the pathogenesis and progress of collagen-related disorders, including liver, kidney, heart, lung, and skin fibrosis, as well as keloid. This review provides a comprehensive summary of the regulatory mechanisms of both traditional and novel PTMs in collagen metabolism and collagen-related diseases. Furthermore, we summarize the drugs that modulate PTMs and their effects, with the aim of elucidating the pathophysiology of collagen-related diseases and provide new insights for their diagnosis, prevention, and treatment.

AIM: To delineate the specific mutation responsible for retinitis pigmentosa(RP)in a Yi pedigree, and to analyze the correlation of RHO gene mutation with clinical phenotype.METHODS:A comprehensive clinical evaluation was conducted on the proband diagnosed with RP and other familial members, complemented by a thorough ophthalmic examination. Peripheral blood samples were obtained from the proband and familial members, from which genomic DNA was extracte. Subsequent whole exome sequencing(WES)was employed to identify the variant genes in the proband. The identified variant gene was validated through Sanger sequencing, then an in-depth analysis of the mutation genes was carried out using genetic databases to ascertain the pathogenic mutation sites. Furthermore, an exhaustive analysis was performed to delineate the genotype and phenotype characteristics.RESULTS:The RP pedigree encompasses 5 generations with 42 members, including 19 males and 23 females. A total of 13 cases of RP were identified, consisting of 4 males and 9 females, which conforms to the autosomal dominant inheritance pattern. The clinical features of this family include an early onset age, rapid progression, and a more severe condition. The patients were found to have night blindness around 6 years old, representing the earliest reported case of night blindness in RP families. The retina was manifested by progressive osteocytoid pigmentation of the fundus, a reduced visual field, and significantly decreased or even vanished a and b amplitudes of ERG. The combined results of WES and Sanger sequencing indicated that the proband had a heterozygous missense mutation of the RHO gene c.1040C>T:p.P347L, where the 1 040 base C of cDNA was replaced by T, causing codon 347 to encode leucine instead of proline. Interestingly, this mutation has not been reported in the Chinese population.CONCLUSION:This study confirmed that the mutant gene of RP in a Yi nationality pedigree was RHO(c.1040C>T). This variant leads to the change of codon 347 from encoding proline to encoding leucine, resulting in a severe clinical phenotype among family members. This study provides a certain molecular, clinical, and genetic basis for genetic counseling and gene diagnosis of RHO.

Anterior cruciate ligament (ACL) injury of the knee is a common sports injury that leads to knee instability, articular cartilage degeneration, periarticular ligaments and meniscus injuries. Arthroscopic anterior cruciate ligament reconstruction (ACLR) is the gold standard in the treatment of ACL injuries, but femoral fixation, being one of the main factors affecting postoperative function after ACLR, remains controversial with various methods and no universal standard. Interference screws as a commonly used fixation method are made of various materials, among which metal screws provide strong fixation but have the disadvantages of graft damage, interference with the MRI examination, and a removal surgery. Degradable metal has good mechanical properties but its degradation is unpredictable. Bioabsorbable interference screws do not require a second operation and do not interfere with the MRI examination, but there are risks of screw breakage, dislocation, and bone tunnel widening. Sheathed interference screws increase the tendon-bone contact area but require a high level of integrity of the bone tunnel. Suspension fixation, the most commonly used method for ACLR femoral side, provides high initial strength, but may cause tendon lengthening, wiper effect and bungee effect. Cross-pin fixation such as Rigidfix, fixes the graft with two absorbable transverse nails with even stress distribution. However, it has a limited choice of femoral tunnel location,poses a risk of cross-pin fracture, and is not suitable for patients with tendons smaller than 7 mm in diameter. Over-the-top fixation does not need the building of a femoral tunnel and is more commonly used in skeletally immature, partial ACL injuries and ACLR revision surgery, where damage to the epiphysis can be avoided and can be used as a means of reinforcement. However, it is not sufficient in patients with high requirements for knee flexion stability and requires longer tendon graft.

With the popularity of sports, the number of anterior cruciate ligament (ACL) injuries in children is increasing year by year. Most ACL injuries in children are tibial avulsion fractures or ACL body tears, seriously affecting the health and sports level of the patients. Due to the special anatomical structure of the patients, unclosed epiphysis makes the diagnosis and treatment of ACL injuries more complex. It is necessary to choose the optimal treatment regimen according to the bone maturity and the type and degree of ACL injuries to reduce the damage to the epiphysis and avoid the impact on the growth and development of the patients. It was treated with non-surgical treatment and then ACL reconstruction when the bones were mature in the past, which could cause secondary meniscus and cartilage damage. In recent years, non-surgical treatment has mainly been indicated for children with low-degree ACL injuries and small demand for exercise. With the increased ratio of early surgical treatment, the patients′ levels of recovery and return to sports after injury have been improved. However, improper surgery may still lead to complications such as growth and development disorders and postoperative re-injuries. Different from traditional ACL reconstruction, personalized diagnosis and treatment regimen of ACL injuries are very important for the patients at different stages of growth and development. For a better understanding of the diagnosis and treatment of ACL injuries in children, the authors reviewed the research progress on the diagnosis and treatment of ACL injuries in children from the aspects of the characteristics, diagnosis and evaluation, treatment methods, etc., hoping to provide a reference for the personalized diagnosis and treatment.

Objective To analyze the epidemiological characteristics of occupational hand-arm vibration disease (OHAVD) in Guangdong Province from 2006 to 2022. Methods The data of newly reported OHAVD cases and suspected occupational disease cases in Guangdong Province from 2006 to 2022 was collected from the Report Card of Occupational Diseases and Report Card of Suspected Occupational Diseases using Occupational Diseases and Health Hazard Factors Monitoring Information System under China Disease Prevention and Control Information System. Epidemiological characteristics of the newly reported OHAVD cases and related suspected occupational disease reports were analyzed. Results A total of 660 newly reported OHAVD cases were reported in Guangdong Province from 2006 to 2022. The number of cases showed a periodic fluctuating trend over the years. Males accounted for 98.64% of the newly reported OHAVD cases with a median age of 38 years and a median hand-transmitted vibration exposure period of 8.7 years. These cases were predominantly distributed in the Pearl River Delta region, including Zhongshan City, Dongguan City, Guangzhou City, Shenzhen City and Foshan City, accounting for 99.25%. The manufacturing enterprises had 98.79% of the cases, investment enterprises of Hong Kong, Macao and Taiwan merchants of China had 83.18% of the cases, and large- and medium-sized enterprises had 92.73% of the cases. The 660 cases were distributed in 440 enterprises, but there were some characteristics of group outbreaks. There were 20 enterprises (4.55% of the total number of enterprises) had more than three cases involving 219 cases (33.18%). There were five enterprises which had more than 10 cases and the cases number ranged from 12 to 56. Among 382 newly reported OHAVD cases from 2014 to 2022, 44.24% were identified as suspected occupational diseases before diagnosis, of which 59.76% (101/169) were determined by occupational health inspection institutions. Conclusion Newly reported OHAVD cases in Guangdong Province were aggregated in terms of regional distribution, industry, enterprise ownership, and enterprise scale, with a risk of group outbreaks. It is suggested to enhance the OHAVD prevention and control in male workers exposed to hand-transmitted vibrations in the Pearl River Delta's manufacturing enterprises.

BACKGROUND:Currently,there have been a variety of conservative and surgical treatment plans for spontaneous osteonecrosis of the knee,achieving excellent results.However,a broad consensus on indication and guide of surgical treatment has not been announced.In clinical practice,there is still a misunderstanding that unicondylar replacement or total knee arthroplasty should be performed upon the discovery of spontaneous osteonecrosis of the knee,while an urgent need for universal access to the concept of stepwise therapy. OBJECTIVE:To summarize and find the factors leading to the poor effect of conservative treatment in spontaneous osteonecrosis of the knee,which occurred on the medial femoral condyle,from the literature and clinical cases,at the same time,combined with the Koshino stage,to propose the strategy of stepwise spontaneous osteonecrosis of the knee treatment on the medial femoral condyle. METHODS:A systematic search of the literature database was conducted to summarize the factors leading to poor outcomes of conservative treatment in spontaneous osteonecrosis of the medial femoral condyle.Meanwhile,according to the Clinical&Health Records for analytics&Sharing system,the cases receiving conservative and surgical treatment in spontaneous osteonecrosis of the medial femoral condyle in the Department of Orthopedics of Guangdong Provincial Hospital of Chinese Medicine from January 2017 to January 2023 were analyzed retrospectively,then the causes of success and failure in typical cases were summarized and analyzed. RESULTS AND CONCLUSION:(1)Early diagnosis and treatment of spontaneous osteonecrosis of the knee were very important for prognosis.For sudden knee pain in some patients,if no obvious abnormality was found in the X-ray examination,and the symptoms persisted and could not be relieved for more than 1 week,an MRI examination was recommended to detect early spontaneous osteonecrosis of the knee.(2)The X-ray images of Koshino stage 1 and stage 2 of spontaneous osteonecrosis of the medial femoral condyle were difficult to be distinguished,which needed to be probed by MRI.MRI images of Koshino stage 1 were mainly characterized by bone marrow edema,and an osteonecrosis area with a clear boundary was not formed,while MR images of Koshino stage 2 showed a necrotic area with a clear boundary.(3)Five factors leading to the poor effect of conservative treatment on spontaneous osteonecrosis of the medial femoral condyle were summarized:a.The necrotic area was＞5 cm2;b.The necrotic area accounted for more than 40%of the condyle;c.relative compression percentage of medial meniscus≥33%(with or without medial meniscus injury and subchondral bone marrow edema);d.MRI depth of necrotic area(anterior-posterior diameter of sagittal necrotic area)＞20 mm;e.varus deformity of lower limb＞6°.(4)Conservative treatment of spontaneous osteonecrosis of the knee in Koshino stage 1 was good.For spontaneous osteonecrosis of the knee in Koshino stage 2,conservative treatment was preferred or combined with drilling decompression.If there was no relief or improvement of symptoms or in MRI after 3 months,while the patient had any of the previous five factors,then knee preservation surgery should be considered.For spontaneous osteonecrosis of the knee in Koshino stage 3 and stage 4,knee preservation surgery should be selected based on the previous five factors,including age,gender and activity level of the patient.Total knee arthroplasty was used for spontaneous osteonecrosis in Koshino stage 4,which was associated with symptomatic patellofemoral arthritis,valgus alignment,or necrotic area,which greatly affected the stability of unicondyle prosthesis.

Objective:To investigate the clinical efficacy of over-the-top reconstruction combined with the modified Lemaire technique in the treatment of anterior cruciate ligament (ACL) injuries with pivot-shift positive.Methods:From March 2020 to October 2021, a total of 46 patients with ACL injury and pivot-shift test grade II or above were admitted to Xinhua Hospital Affiliated to Dalian University. There were 28 males and 18 females, aged 28.0±10.5 years (range, 15-45 years). All cases were unilateral, including 17 cases of left knee and 29 cases of right knee. The pivot-shift test showed that 30 cases were grade II and 16 cases were grade III, and the cause of injury was sports injury. The semitendinosus muscle and gracilis muscle were harvested, and the ACL was reconstructed with the over-the-top combined modified Lemaire technique. The International Knee Documentation Committee (IKDC) score, Lysholm score and KT-2000 side-to-side difference before and after operation were compared.Results:All patients successfully completed the operation and were followed up for 26.6±2.3 months (range, 24-28 months). The Lysholm scores of the patients at 3 months and 24 months after operation were 73.6±4.3 and 91.6±2.8, which were higher than those before operation (58.5±4.6), and the difference was statistically significant ( F=18.351, P<0.001). The IKDC scores of patients at 3 months and 24 months after operation were 59.0±2.0 and 91.8±3.2, respectively, which were higher than those before operation 50.3±2.8, and the difference was statistically significant ( F=17.290, P<0.001). The side-to-side difference of KT-2000 was 1.7±0.8 mm and 1.5±0.4 mm at 3 and 24 months after operation, respectively, which was lower than that before operation (5.9±1.1 mm), and the difference was statistically significant ( F=14.192, P<0.001). At 24 months after operation, 3 patients had pivot shift test grade I and 4 patients had Lachman test grade I, but they complained of good knee stability and did not receive further treatment. At the last follow-up, there were no complications such as incision and intra-articular infection, deep vein thrombosis, knee stiffness, quadriceps musculus ossificans myositis, and reconstruction ligament rupture. All patients returned to sports with an average time of 15.7±2.6 months (range, 12-24 months). Conclusion:Over-the-top reconstruction combined with the modified Lemaire technique for the treatment of ACL injury with positive pivot shift test effectively improves knee function and promotes the patient's return to sports, with a low incidence of surgical complications.
