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 construct a post competency evaluation index system for nurses in medical and nursing institutions.Methods:Using the competency iceberg model as the theoretical framework, through literature review and qualitative interview, the first draft of the competency evaluation index system of nurses in medical and nursing institutions was constructed. From September to November 2022, 24 experts were invited for two rounds of expert letter consultation. After collecting expert opinions, the final draft was formed after screening, modification and improvement of each index, and the weight of each evaluation index was determined by analytic hierarchy process.Results:The effective recovery rates of two rounds of correspondence were 75.0% (18/24) and 100.0% (18/18), and the expert authority coefficients were 0.917 and 0.909, respectively. The Kendall's coordination coefficient of all indicators of the second round of correspondence was 0.210 ( P< 0.01). The final evaluation index system consisted of 6 first-level indicators, 25 second-level indicators and 86 third-level indicators. All judgment matrices had consistency. Conclusions:The competency evaluation index system for nurses in medical and nursing institutions constructed in this study has good reliability and applicability, which can provide reference basis for the selection, training, assessment and management of nurses in medical and nursing institutions.

Objective:To analyze clinical factors related to nosocomial infection in children with extracorporeal membrane oxygenation(ECMO)support.Methods:General data, infection data and relevant factors in children with ECMO support in Bayi Children′s Hospital, the 7 th Medical Center of People′s Liberation Army General Hospital and Henan Provincial People′s Hospital from September 2012 to February 2020 were reviewed.Relevant factors of nosocomial infection in them were analyzed. Results:Among 163 cases, 36(22.1%) children supported with ECMO had infections during the period of ECMO, and 72 pathogenic microorganisms were detected, including 67 bacteria (33 Acinetobacter baumannii, 21 Klebsiella pneumoniae, and 6 Pseudomonas aeruginosa) and 5 fungi.Pathogens from the respiratory system, blood system, urinary tract and abdominal cavity were detected in 45 cases(62.5%), 25 cases (34.7%), 1 case (1.4%), and 1 case (1.4%), respectively.Drug sensitivity analysis of the Acinetobacter baumannii showed that it was the extensively resistant strain.Compared with uninfected children supported with ECMO, ECMO support time[(10.0±6.7) d], hospitalization[(34.0±25.3) d], hospitalization cost[(234 368±113 234) yuan], preoperative oxygenation index(52.8±23.0) and lactate value[(9.6±5.9) mmol/L]were significantly higher in nosocomial infection ones[(4.6±3.2) d, (24.3±19.8) d, (161 416±65 847) yuan, 35.6±10.4, (5.6±5.4) mmol/L] supported with ECMO (all P<0.05). There was no significant difference in the mortality between 2 groups ( P>0.05). In addition, lactate level (9.8 mmol/L) and oxygenation index (36.0±12.7) were significantly higher in died children(2.7 mmol/L, 22.1±10.4) with nosocomial infection during the period of ECMO support than those of survivors (all P<0.05). Multivariate Logistic regression analysis showed that ECMO support time( OR=7.054, 95% CI: 2.206-25.525) and preoperative lactate value( OR=2.250, 95% CI: 1.378-4.611) were independent risk factors of nosocomial infection. Conclusions:Correcting underlying diseases of ECMO supporting and shortening the duration of ECMO can reduce the incidence and mortality of nosocomial infection in children who are supported with ECMO.

Objective: To analyze the epidemiological characteristics of coronavirus disease 2019 （COVID-19） cases reported in Ningbo from January 22 to February 22, 2020, so as to provide guidance for the prevention and control of the COVID-19 epidemic. Methods: The confirmed cases of COVID-19 reported by Ningbo were selected from National Diseases Prevention and Control Information System to analyze the epidemiological characteristics by descriptive epidemiological method, including time, spatial and population distribution, clinical symptoms and exposure history. Results: A total of 157 confirmed cases of COVID-19 were reported and there was no death. The first confirmed case was reported on January 22. On the incidence curve, the peak was from January 22 to February 4, with a maximum of 15 cases in a single day. The incidence curve presented sustained human-to-human transmission. The number of the cases showed a declining trend from February 5. The confirmed cases were reported in all 10 counties（cities or districts）,among which 69（43.95%）cases were reported in Haishu District. The confirmed cases were mainly 30-69 years old,accounting for 78.34%;were mainly farmers,household workers and retired people,accounting for 59.87%;and were mainly clinically mild,accounting for 87.90%.There were 51 imported cases, accounting for 32.48%. The initial confirmed case was a local case. In the early stage of the epidemic, local cases and imported cases prevalent together,which was due to the outbreak caused by the large-scale buddhist activity on January 19.This event resulted in 67 confirmed cases and 15 asymptomatic cases. There totally reported 22 clusters with 138 （87.90%）confirmed cases. Conclusions In the early stage of the COVID-19 epidemic in Ningbo, the imported cases and local cases prevalent at the same time. Most of the cases were female, aged from 30 to 69 years, and their occupation were farmers, household workers and retired people. With comprehensive measures taken, the epidemic of COVID-19 in Ningbo have been under control.

Objective:To evaluate the efficacy and mechanism of continuous blood purification(CBP) in the treatment of severe sepsis in children.Methods:A total of 42 patients with severe sepsis were enrolled in the study.According to the parents undefined desire to treatment, on the basis of the same treatment condition, 30 cases in the blood purification group were treated with CBP, and 12 cases in the control group were given the routine treatment without CBP treatment.The difference of each index between the two groups at the baseline(before treatment) and 72 hours after treatment were observed.Results:The differences of heart rate, mean arterial pressure and brain natriuretic peptide before and after treatment in the blood purification group were significantly higher than those in control group( P<0.05), and the differences of oxygenation index, 24-hour average urine volume, blood urea nitrogen, creatinine and Glasgow coma score in the blood purification group were significantly higher than those in control group( P<0.05). The difference of capillary refill time, lactic acid and central venous oxygen saturation in blood purification group were significantly higher than those in control group( P<0.05). The level of white blood cell count, C-reactive protein, procalcitonin and interleukin-6 in blood purification group were significantly higher than those in control group, with all significant difference( P<0.05). There was significant difference in critical illness score between two groups after treatment and before treatment.The mortality rate of the blood purification group was significantly lower than that in control group( P<0.01). Conclusion:CBP can improve cardiovascular function, brain function, renal function, tissue perfusion, inflammation index, internal environment, and improve the score of children with severe sepsis.

Since December 2019, novel coronavirus pneumonia (NCP) has been reported in Wuhan, Hubei Province, and spreads rapidly to all through Hubei Province and even to the whole country. The virus is 2019 novel coronavirus (2019-nCoV), never been seen previously in human, but all the population is generally susceptible. The virus spreads through many ways and is highly infectious, which brings great difficulties to the prevention and control of NCP. Based on the needs of orthopedic trauma patients for emergency surgery and review of the latest NCP diagnosis and treatment strategy and the latest principles and principles of evidence-based medicine in traumatic orthopedics, the authors put forward this expert consensus to systematically standardize the clinical pathway and protective measures of emergency surgery for orthopedic trauma patients during prevention and control of NCP and provide reference for the emergency surgical treatment of orthopedic trauma patients in hospitals at all levels.

Objective: To investigate the clinical features and prognosis of intracranial embryonal tumors in children. Methods: Clinical data of 27 patients with intracranial embryonal tumors who were admitted to Beijing Shijitan Hospital, Capital Medical University be-tween May 2011 and December 2018 were retrospectively analyzed. Results: The study included 27 patients, comprising 17 male and 10 female children, with a median age of 7 years. Twelve patients underwent gross total resection, and 15 patients underwent subto-tal resection. After surgery, all 27 patients underwent craniospinal irradiation. The dose of craniospinal irradiation was 27-30.6 Gy, and the dose of the tumor bed was 55.8-60 Gy. Twenty-two patients underwent chemotherapy regimen composed of irinotecan, vtncris-tine, etoposide, nedaplatin after radiotherapy. The median follow-up period was 22 (4-93) months. Nine patients are alive without lo-cal or distant recurrence. Eighteen patients died; the causes of death were intracranial recurrence and spinal cord metastasis. The 1-, 3-, and 5-year survival rates were 79.4%, 50.2%, and 36.5%, respectively. Conclusions: Intracranial embryonal tumors in children are rare and malignant and can metastasize along the neuroaxis. Surgery, adjuvant radiotherapy, and chemotherapy are important for pa-tients with intracranial embryonal tumors. Moreover, the prognosis is poor.

Objective: To evaluate the safety and efficacy of ombitasvir/paritaprevir/ritonavir (OBV/PTV/r) 25/150/100 mg once daily combined with dasabuvir 250mg, twice daily in non-cirrhotic Chinese adult patients with newly diagnosed and treated chronic HCV genotype 1b infection. Methods: A randomized, double-blind, placebo-controlled, multicenter phase 3 clinical trial was conducted in mainland China, Korea, and Taiwan.Safety and efficacy of OBV/PTV/r plus DSV administered for 12 weeks were evaluated in a newly diagnosed and treated (interferon alpha /pegylated interferon alpha) and ribavirin non-cirrhotic adults with chronic HCVgenotype 1b infection. Patients randomly received OBV/PTV/r plus DSV for 12 weeks (Group A), or placebo for 12 weeks (Group B) followed by an open-label phase of OBV/PTV/r plus DSV for 12 weeks. Sustained response (SVR12) rate obtained at 12 weeks and (SVR24) 24 weeks after discontinuation of treatment, and the incidence of adverse events and laboratory abnormalities after double-blind and open-label phase treatment were assessed. Results: A total of 410 cases of Chinese patients were included and randomly assigned to group A and B (with 205 cases in each group) in a 1:1 ratio. The rates of SVR12 and SVR24 were 99% (95% CI: 94.8% - 99.8%) in the newly diagnosed patients in group A (205 patients) and the rates of SVR12 and SVR24 were 100% in treated patients (95% CI: 96.3% - 100%). Different baseline characteristics had no effect on SVR12 and SVR24 rates. Most of the adverse events occurred were mild, asymptomatic, and≥ 3 laboratory abnormalities during treatment were rare, including elevation of alanine aminotransferase (2 cases in double-blind stage A group), aspartate aminotransferase (Double-blind stage A (3 cases) and total bilirubin (1 case in open-label phase B group); however, those mild adverse events could be recovered after drug withdrawal or discontinuation. only1 person discontinued drugs due to adverse events (Group B, open-label phase). Conclusion The 12 weeks treatment course of OBV/PTV/r combined with DSV produced 99% ~ 100% rates of SVR12 and SVR24 in non-cirrhotic Asian adult patients with newly diagnosed and treated chronic HCV genotype 1b infection, and the tolerance and safety were good.

OBJECTIVETo identify the feasibility and safety of fossa infratemporalis approach for blind-needle at sphenopalatine ganglion so as to provide anatomical evidence for the operation and the prevention of non-immediate adverse reaction.

METHODSThe variations of pterygopalatine fossae in sixty dry skulls were observed by selecting measuring points for facial skull width. The brains of six wet skulls were taken out,then acupuncture of fossa infratemporalis approach was applied. Sphenopalatine ganglion was separated accurately with the pterygopalatine segment of maxillary arteria retained in the pterygopalatine fossa after its paries posterior was opened. We detected whether the needle was inserted into pterygopalatine fossa. Measurements showed needle inserted depth, facial skull width,the distance between the needle and sphenopalatine ganglion,the distance between the needle and the pterygopalatine segment of maxillary arteria,the distance between the pterygopalatine segment of maxillary arteria and the crotaphitic nerve in pterygopalatine fossa.

RESULTSThe distance between the slight hollow under bilateral arcus superciliaris was selected as skull width, and 3 dry skulls showed the variation of pterygopalatine fossa. Needles were inserted into the pterygopalatine fossae of the wet skulls (12 times). The proportion of the inserting depth to the distance between the slight hollow under bilateral arcus superciliaris was 44%-54%. Only twice did the needle contact sphenopalatine ganglion. The average distances between the sphenopalatine ganglion and the needle were (5.88±3.70) mm in the left side and (6.43±5.54) mm in the right side. The average distances between the needle and the pterygopalatine segment of maxillary arteria were (2.77±3.99) mm left and (2.53±3.10) mm right. The average distances between the pterygopalatine segment of maxillary arteria and the crotaphitic nerve in pterygopalatine fossa were (2.83±4.05) mm left and (2.67±4.95) mm right. The mean data between the two sides had no statistic significance about all the above indices (all>0.05).

CONCLUSIONSFossa infratemporalis approach is feasible for blind-needle at sphenopalatine ganglion with less possibility to contact it. The effect of treating nasitis may achieved by little distance to nerve. Pricking at the pterygopalatine segment of maxillary arteria may induce non-immediate adverse reaction. The safety and efficacy should be comprehensively considered. There is a proportional relationship between the width of the skull and the insertion depth of the needle. The inserting depth of 44 percent may appropriate accounted for skull width.

objective:To investigate the clinical features and prognosis of pinealoblastoma in children. Methods:The clinical data of 10 patients with pinealoblastoma were retrospectively analyzed. These patients were admitted to the Department of Radiation Oncology, Beijing Shijitan Hospital, Capital Medical University from December 2011 to December 2015. Results:This study included 10 patients, with 8 males and 2 females, with a median age of 7 years. Of the 10 patients, 5 underwent gross total resection and 5 underwent sub-total resection. The 10 patients were exposed to craniospinal irradiation after surgery. The median doses of craniospinal irradiation and tumor bed were 30.6 (25.5-36) Gy and 55.8 (50.4-60) Gy, respectively. Of the 10 patients, 4 underwent chemotherapy 1 month af-ter radiotherapy. The median follow-up period was 16.5 (1.5-49) months. The 10 patients survived. No local and distant recurrences were observed. Conclusion:Pinealoblastomas are rare, malignant, and pineal regional lesions that can metastasize along the neuroax-is. Surgery combined with adjuvant radiotherapy and chemotherapy should be applied to patients with pinealoblastoma. Prognosis is also favorable.
