Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

ObjectiveTo investigate effect of conducting training of autism spectrum disorder （ASD） early screening skill on improving the ability to early identify ASD of medical staffs in primary care hospitals. MethodsIn September 2021， the training of ASD early screening skills was carried out for medical staffs from 20 primary care hospitals in Chengdu. After training， the training effect was evaluated. The numbers of referrals from primary care hospitals to superior hospitals， confirmed ASD as well as their average diagnostic age of children with ASD before and after training were used as evaluation indicators. ResultsAfter training， the number of children with suspected ASD referred by primary care hospitals was more than that before training ［（16.65±11.60） vs. （3.40±2.23）， t=5.431， P<0.01］， the number of children diagnosed with ASD was more than that before training［（6.85±4.93） vs. （2.45±1.67）， t=4.171， P<0.01］， and the differences were statistically significant. As for the diagnosed age of ASD children， after training， the average age was lower than that before training ［（34.95±11.67） vs. （42.2±14.64）， t=-2.553， P=0.019］. ConclusionTraining of ASD early screening skills for medical staffs in primary care hospitals may help to improve their ability to early screening ASD children.

OBJECTIVE: To explore the genetic basis for an individual with a para-Bombay phenotype. METHODS: A proband with mismatched forward and reverse serotypes for the ABO blood group was identified. Weakly expressed ABH blood type antigen on the surface of red blood cells was verified by absorption and release test, and the blood group substances in saliva was detected by sialic acid test. Exons 6 and 7 of the ABO gene and exons of the FUT1 and FUT2 genes were subjected to direct sequencing. RESULTS: The proband was found to be of O type by forward ABO serotyping and AB type by reverse ABO serotyping, though H and substance A and B were detected in her saliva. DNA sequencing revealed that she has harbored c.35C/T, c.328G/A, and c.504delC compound heterozygous variants of the FUT1 gene. Haploid analysis showed that her FUT1 genotype was h328A/h35T+504delC, which has been uploaded to the NCBI website (No. MW323551). CONCLUSION The para-Bombay phenotype of the proband may be attributed to the novel compound heterozygous variants including c.504delC of the FUT1 gene, which may affect its function by altering the activity of FUT1 glycotransferase.

Objective:To evaluate the long-term efficacy of double-tunnel peroral endoscopic myotomy (POEM) and traditional POEM in the treatment of achalasia cardia.Methods:A randomized controlled trial was performed on the data of 30 patients with achalasia cardia, who underwent POEM in the First Affiliated Hospital of Nanjing Medical University from June 2018 to June 2019. The 30 consecutive patients were randomly assigned to double-tunnel POEM group (15 cases, a second tunnel was established opposite to the traditional one) and traditional POEM group (15 cases). Intraoperative information was recorded, and patients were followed up regularly to compare the efficacy and complications between the two groups.Results:Double-tunnel POEM and traditional POEM were all completed with technical success. There were no significant differences in the intraoperative complications (5/15 VS 4/15, P=1.000), hospitalization time or cost between the two groups. The follow-up time was 17.20±4.83 months and 15.33±4.67 months in the traditional POEM group and the double-tunnel POEM group, respectively. The Eckardt scores after surgery between the two groups had no significant difference [1.53 (2.00) VS 1.60 (3.00), Z=-0.363, P=0.744]. The symptom relief cases were both 14 in the two groups. The postoperative 4-second integrated relaxation pressure (4 s IRP) of the double-tunnel group (11.27±3.14 mmHg) was significantly lower than that of the traditional group (15.05±4.21 mmHg, t=2.794, P=0.009). There was no significant difference in postoperative gastroesophageal reflux disease questionnaire scores between the two groups (4.40±1.64 VS 4.20±1.42, t=0.357, P=0.724). Conclusion:Double-tunnel POEM has almost the same efficacy as the traditional POEM except for a lower post-POEM 4 sIRP.

Objective:To investigate the influencing factors of the therapeutic effect of epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) in patients with epidermal growth factor receptor (EGFR) mutant advanced non-small cell lung cancer (NSCLC).Methods:The clinical data of 104 EGFR mutant advanced NSCLC patients who received EGFR-TKI treatment in Wuxi No.2 Hospital Affiliated to Nanjing Medical University from January 2015 to October 2019 were collected. The correlation of different types of EGFR mutation with the clinicopathological characteristics, the hematological examination results and the treatment mode of patients was analyzed. Cox proportional hazard model was used to analyze the association of the progression-free survival (PFS) time of patients receiving EGFR-TKI treatment with the different types of EGFR mutation, the clinicopathological characteristics, hematological related indexes and treatment mode. Kaplan-Meier method was used to analyze the independent influencing factors for the PFS of the stratified patients.Results:The overall disease control rate (DCR) of patients receiving EGFR-TKI treatment was 92.3% (96/104). Cox univariate analysis showed that the levels of carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), D-dimer, and previous surgical treatment history of patients receiving EGFR-TKI treatment were associated with PFS of patients (all P < 0.05). Cox multi-factor analysis showed that EGFR mutation type ( HR =2.371, 95% CI 1.298-4.332, P = 0.005), combination therapy ( HR = 0.489, 95% CI 0.245-0.978, P = 0.043) and choice of therapeutic drugs ( HR = 0.261, 95% CI 0.113-0.606, P = 0.002) were independent influencing factors for the PFS of patients receiving EGFR-TKI treatment. The PFS of EGFR 19 exon-mutant patients with advanced NSCLC was longer than that of those with EGFR 21 exon-mutant (median PFS time: 14.0 months vs.9.5 months, P<0.05); the PFS of combination of radiotherapy or chemotherapy was longer than that of EGFR-TKI single therapy (median PFS time: 15.0 months vs. 9.0 months, P<0.05), the PFS of patients receiving erlotinib was better than that of those receiving gefitinib ( P<0.05). According to EGFR mutation types, it was found that EGFR 19 exon-mutant patients receiving EGFR-TKI in first-line treatment could obtain better PFS than those who receiving EGFR-TKI in second-line and above treatment (median PFS time: 14.0 months vs. 9.5 months, P<0.05). When receiving EGFR-TKI, EGFR 19 exon-mutant patients with CA125 <85 U/ml could obtain longer PFS time than those with CA125 ≥85 U/ml (median PFS time: 14.0 months vs. 6.5 months, P<0.05). Conclusions:The therapeutic effect of EGFR-TKI in EGFR-mutant patients with advanced NSCLC is positive. EGFR 19 exon-mutant NSCLC patients with low-level CA125 receiving EGFR-TKI in first-line treatment can obtain better PFS.

Objective:To investigate the effects and the mechanism of renal protection of curcumin on oxidative stress and lipid metabolism in diabetic rats.Methods:60 Wistar rats were randomly divided into normal control group ( n=20) and diabetic model preparation group ( n=40). Rats in the normal control group were fed with normal diet, while rats in the diabetes model group were fed with high sugar and high fat diet. After 4 weeks of feeding, rats in the diabetic model preparation group were injected with streptozotocin (60 mg/kg) intraperitoneally once. A total of 35 rats were successfully modeled and then randomly divided into diabetic model group ( n=17) and curcumin group ( n=18). The diabetic model group continued to be fed with high sugar and high fat diet, and the curcumin group was given high sugar and high fat diet and 200 mg/(kg·d) curcumin (1% carboxymethyl fiber sodium prepared into suspension) intervention every day; while the normal control group and the diabetic model group were given 1% carboxymethyl fiber sodium of the same volume. The body weight, kidney index, blood glucose , serum creatinine, urea nitrogen, blood lipid and 24-hour urinary microalbumin excretion rate (24 h UAER) of rats in each group were measured. Superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GSH-Px) and m-alondialdehyde (MDA) in serum and kidney tissues were measured. Results:Compared with the control group, the levels of the body weight, kidney index, blood glucose, serum creatinine, urea nitrogen, triglyceride, total cholesterol and 24 h UAER in the diabetic model group increased significantly. The level of MDA in serum and kidney tissues increased significantly ( P<0.05), while the levels of SOD, CAT and GSH-Px activities in serum and kidney tissues decreased significantly ( P<0.05). Compared with diabetic model group, the levels of the body weight increased, while the kidney index, blood glucose, serum creatinine, urea nitrogen , triglyceride, total cholesterol and 24 h UAER in the curcumin group decreased significantly, the level of MDA in serum and kidney tissues decreased significantly ( P<0.05); the levels of SOD, CAT and GSH-Px in serum and kidney tissues increased significantly ( P<0.05) in the curcumin group. Conclusions:Curcumin may play a renal protective role in diabetic rats by inhibiting oxidative stress in serum and kidney and reducing blood lipid.
