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 As primary Sj?gren's syndrome(pSS)primarily affects the salivary glands,saliva can serve as an indicator of the glands'pathophysiology and the disease's status.This study aims to illustrate the salivary proteomic profiles of pSS patients and identify potential candidate biomarkers for diagnosis. Methods The discovery set contained 49 samples(24 from pSS and 25 from age-and gender-matched healthy controls[HCs])and the validation set included 25 samples(12 from pSS and 13 from HCs).Totally 36 pSS patients and 38 HCs were centrally randomized into the discovery set or to the validation set at a 2:1 ratio.Unstimulated whole saliva samples from pSS patients and HCs were analyzed using a data-independent acquisition(DIA)strategy on a 2D LC-HRMS/MS platform to reveal differential proteins.The crucial proteins were verified using DIA analysis and annotated using gene ontology(GO)and International Pharmaceutical Abstracts(IPA)analysis.A prediction model for SS was established using random forests. Results A total of 1,963 proteins were discovered,and 136 proteins exhibited differential representation in pSS patients.The bioinformatic research indicated that these proteins were primarily linked to immunological functions,metabolism,and inflammation.A panel of 19 protein biomarkers was identified by ranking order based on P-value and random forest algorichm,and was validated as the predictive biomarkers exhibiting good performance with area under the curve(AUC)of 0.817 for discovery set and 0.882 for validation set. Conclusions The candidate protein panel discovered may aid in pSS diagnosis.Salivary proteomic analysis is a promising non-invasive method for prognostic evaluation and early and precise treatments for pSS patients.DIA offers the best time efficiency and data dependability and may be a suitable option for future research on the salivary proteome.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM To establish a UPLC-MS/MS method for the simultaneous content determination of gallic acid,protocatechuic acid,neomangiferin,catechin,caffeic acid,mangiferin,isomangiferin,albiflorin,paeoniflorin,vitexin,liquiritin,scutellarin,baicalin,liquiritigenin,timosaponin BⅡ,quercetin,wogonoside,benzoylpaeoniflorin,isoliquiritigenin,honokiol,magnolol,norarecaidine,arecaidine,arecoline,epicatechin,baicalein,glycyrrhizinate and wogonin in Dayuan Drink.METHODS The analysis was performed on a 35℃thermostatic Syncronis C18 column(100 mm×2.1 mm,1.7 μm),with the mobile phase comprising of 0.1%formic acid-acetonitrile flowing at 0.3 mL/min in a gradient elution manner,and electron spray inoization source was adopted in positive and negative ion scanning with select reaction monitoring mode.RESULTS Twenty-eight constituents showed good linear relationships within their own ranges(R2≥0.991 0),whose average recoveries were 95.60%-103.53%with the RSDs of 0.60%-5.45%.CONCLUSION This rapid,simple,selective,accurate and reliable method can be used for the quality control of Dayuan Drink.

Objective To explore the effectiveness and safety of guiding painless gastroscopic entry with plica aryepiglottica movement as the mark.Methods A total of 200 patients with elective painless gas-troscopic examination from January 2022 to August 2022 were selected,92 males and 108 female,aged 18-60 years old,BMI 18-30 kg/m2 and ASA grade Ⅰ-Ⅲ.The patients were divided into the two groups:the con-trol group (group C) and observation group (group O) by adopting the random number table method,100 ca-ses in each group.The disappearance of eyelash reflex in the group C served as the entry timing of gastrosco-py,while the plica aryepiglottica non-movement under the gastroscopic view in the group O served as the en-try timing of gastroscopy.The bispectral index (BIS) value during gastroscopic operation persistently main-tained 40-60.The main observation indicators were the adverse reactions caused by gastroscopic operation (body movement reactions,bucking,hiccup,laryngeal spasm,etc.),and the secondary observation indicators were:general data of the two groups,SpO2,HR,SBP and DBP values after entering the room (T0),at the en-try time of gastroscopy (T1),3 min after gastroscopic entry (T2),6 min after gastroscopic entry (T3) and at the time of gastroscopic retraction (T4),and the time of medication to gastroscopy,gastroscopic operation time and intraoperative medication supplementation.Results A total of 192 cases were ultimately included,99 cases in the group C and 93 cases in the group O.There was no statistically significant difference in general da-ta between the two groups (P>0.05);compared with the group C,the use amount of cyclophosphamide dur-ing anesthesia induction in the group O was increased (P<0.05).Compared with the group C,the incidence rates of body movement reaction,bucking,hiccup and total adverse reactions in the group O were decreased (P<0.05);SpO2,HR,SBP and DBP at different time points had no statistically significant differences be-tween the two groups (P>0.05).Conclusion Using the glottic movement as the marker to guide the pain-less gastroscopy entry is effective and safe,and could reduce the adverse reactions such as body movement re-action,bucking and hiccup caused by gastroscopic entry.Observing the plica aryepiglottica movement in the gastrocopic entry operation is simple and easy to perform,which could serve an objective gastroscopic entry timing mark and is worth promoting and using in clinic.

Objective:To investigate the effect of genetic polymorphism of MTHFR C677T (rs1801133) on methotrexate (MTX) related toxicity in pediatric mature B-cell lymphoma patients. Methods:Fifty-eight intermediate and high risk patients under 18 years of age with mature B-cell lymphoma who received 5 g/m2 MTX (24 h intravenous infusion) in Sun Yat-sen University Cancer Center from August 2014 to December 2021 were included,and their toxicity of high-dose MTX (HD-MTX) were monitored and analyzed. Results:Among the 58 pediatric patients,the number of CC,CT,and TT genotypes for MTHFR C677T was 33,19 and 6,respectively. A total of 101 courses of HD-MTX therapy were counted,of which plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion were observed in 35 courses,≤0.2 μmol/L in 66 courses. Inter-group comparison showed that plasma MTX level>0.2 μmol/L at 48 h post-MTX infusion increased the risk of developing oral mucositis (P<0.05). Compared with wild-type (CC genotype),patients in the mutant group (CT+TT genotype) were more likely to develop myelosuppression,manifested as anemia,leucopenia,neutropenia and thrombocytopenia. However,plasma MTX level at 48 h was not associated with MTHFR C677T gene polymorphism. Conclusion:The risk of developing oral mucositis in children with mature B-cell lymphoma is associated with plasma MTX concentration. Polymorphism of MTHFR C677T gene is not related to plasma MTX concentration in children with mature B-cell lymphoma,but is related to grade Ⅲ to Ⅳ hematological toxicity.

Objective:To investigate the clinical application of Grunenwald incision in cervicothoracic junction surgery.Methods:The clinical data of 25 patients with cervicothoracic junction tumor and 1 patient with cervicothoracic junction trauma in the single treatment group of Department of Thoracic Surgery, the Fourth Hospital of Hebei Medical University from December 2011 to September 2021 were analyzed retrospectively, including 19 males and 7 females, aged 9-73 years old. Among the 26 patients, there were 9 cases of upper mediastinal tumor, 6 cases of superior sulcus tumor, 4 cases of thyroid tumor invading the upper mediastinal, 4 cases of chest wall tumor, 2 cases of esophageal cancer combined with supraclavicular lymph node metastasis, and 1 case of foreign body penetrating injury at the cervicothoracic junction. Grunenwald incision or additional posterolateral thoracic incision, median sternal incision, neck collar incision were used in all patients. The degree of tumor resection was evaluated. The operation time, intraoperative blood loss, length of hospital stay were observed, and the postoperative follow-up was analyzed.Results:There was no perioperative death in the whole group. 14 cases were treated with Grunenwald incision alone, 6 cases with additional posterolateral chest incision, 4 cases with additional neck collar incision, and 2 cases with additional median sternal incision. The tumors were completely resection in 22 cases, palliative tumor resection in 3 cases, and complete foreign body removal in 1 case. Postoperative pathology included 4 cases of schwannoma; 3 cases of lung adenocarcinoma, thyroid cancer and myofibroblastoma, respectively; 2 cases of supraclavicular lymph node metastasis of esophageal cancer and lung squamous carcinoma, respectively; 1 case of large cell neuroendocrine carcinoma, metastatic carcinoma of the first rib after lung squamous cell carcinoma, ganglioneuroma, nodular goiter, hemangioma, well differentiated liposarcoma, vascular endothelial tumor and cavernous angioma, respectively. The operation time was 120-430 min, with a mean of(226.92±88.40)min. The intraoperative blood loss was 100-1 000 ml, with a mean of(273.46±196.34)ml. The length of hospital stay was 6-26 days, with a mean of(12.73±4.46 )days. 26 patients were followed up for 6-130 months, with a mean of(57.88±43.64) months. During the follow-up period, 6 patients died.Conclusion:Grunenwald incision can provide good exposure of the structures near the cervicothoracic junction, preserve the integrity of sternoclavicular joint, reduce shoulder deformity, and has advantages for patients with cervicothoracic junction tumors, high rib resection, and cervicothoracic junction trauma.

Effective treatments for neuropathic pain are lacking due to our limited understanding of the mechanisms. The circRNAs are mainly enriched in the central nervous system. However, their function in various physiological and pathological conditions have yet to be determined. Here, we identified circFhit, an exon-intron circRNA expressed in GABAergic neurons, which reduced the inhibitory synaptic transmission in the spinal dorsal horn to mediate spared nerve injury-induced neuropathic pain. Moreover, we found that circFhit decreased the expression of GAD65 and induced hyperexcitation in NK1R⁺ neurons by promoting the expression of its parental gene Fhit in cis. Mechanistically, circFhit was directly bound to the intronic region of Fhit, and formed a circFhit/HNRNPK complex to promote Pol II phosphorylation and H2B monoubiquitination by recruiting CDK9 and RNF40 to the Fhit intron. In summary, we revealed that the exon-intron circFhit contributes to GABAergic neuron-mediated NK1R⁺ neuronal hyperexcitation and neuropathic pain via regulating Fhit in cis.

OBJECTIVE: To investigate the safety and efficacy of reinforced radiculoplasty in the treatment of symptomatic sacral Tarlov cysts (TCs). METHODS: A retrospective analysis was performed on the clinical data and follow-up data of 71 patients with symptomatic sacral TCs who underwent reinforced radiculoplasty in the Neurosurgery Department of Peking University Third Hospital from June 2018 to March 2021. All the operations were performed under neuroelectrophysiological monitoring. Intraoperative cyst exploration, partial resection of the cyst wall, narrowing of the leak, nerve root sleeve radiculoplasty and artificial dural reinforcement were performed. The incidence of postoperative complications and new neurological dysfunction was analyzed. Visual analogue scale (VAS) was used to assess the changes of pain before and after surgery. The Japanese Orthopedics Association (JOA) low back pain score was used to evaluate the changes in nerve function before and after surgery. RESULTS: In the study, 71 patients had 101 TCs, 19 (18.8%) TCs originated from the left S1 nerve, 26 (25.7%) originated from the left S2 nerve, 3 (3.0%) originated from the left S3 nerve, 14 (13.9%) originated from the right S1 nerve, 33 (32.7%) originated from the right S2 nerve, 6 (5.9%) originated from the right S3 nerve, all the TCs underwent reinforced radiculoplasty. Deep infection (1 case), subcutaneous effusion (1 case), fat li-quefaction (1 case) and urinary tract infection (4 cases) were recorded postoperatively. The patients were followed up for 12-43 months (median, 26 months). Two cases had new urinary retention after operation, and the catheter was removed at the end of the first and second months respectively. One case had new fecal weakness, which improved after 3 months. Compared with preoperation, VAS decreased significantly at the last follow-up [median, 6 (4-9) vs. 1 (0-5), Z=-7.272, P < 0.001], JOA score increased significantly [median, 20 (16-25) vs. 27 (18-29), Z=-7.265, P < 0.001]. There were 18 cured cases (25.4%), 41 excellent cases (57.7%), 8 effective cases (11.3%), and 4 invalid cases (5.6%). The total efficiency was 94.4% (67/71). Two (1.98%) cysts recurred. CONCLUSION For patients with symptomatic sacral TCs, reinforced radiculoplasty can significantly improve the pain and nerve function, which is safe and reliable.
