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.

Objective: To compare the effect of scalp acupuncture and scalp acupuncture plus acupuncture exercise therapy (AET) on walking ability in children with spastic cerebral palsy (CP). Methods: A total of 60 spastic CP children with gross motor function classification system (GMFCS) grades Ⅰ-Ⅲ were divided into a control group and an observation group by the random number table method, with 30 cases in each group. Both groups were treated with the same conventional rehabilitation and scalp acupuncture therapy for CP. The control group received conventional rehabilitation first and then scalp acupuncture. The observation group received AET, which was to receive the conventional rehabilitation and scalp acupuncture simultaneously. Before and after treatment, the clinical efficacy was evaluated by the modified Ashworth scale (MAS) score, scores of dimensions D and E of the gross motor function measure (GMFM) scale, walking speed, and walking distance. Results: During treatment, there were 2 dropouts in the observation group. After 3 courses of treatment, the MAS scores in both the control group and observation group decreased compared with the same group before treatment (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance were increased (P<0.05); the between-group comparison showed that the MAS score in the observation group was lower than that in the control group (P<0.05), and the scores of dimensions D and E of the GMFM, walking speed, and walking distance in the observation group were higher or longer than those in the control group (P<0.05). Conclusion: W ith the same treatments, scalp acupuncture combined with AET is superior to the conventional scalp acupuncture method in reducing lower-limb muscle tone, improving standing balance ability, and walking stability in children with spastic CP.

OBJECTIVE: To assess the association of 7 single nucleotide polymorphisms (SNPs) including rs13278062 (TNFRSF10A), rs3750846 (ARMS2-HTRA1), rs429358 (APOE), rs5817082 (CEPT), rs2043085 (LIPC), rs1626340 (TGFBR1), and rs8135665 (SLC16A8) identified through genome-wide association study (GWAS) with age-related macular degeneration (AMD) among ethnic Han Chinese from Sichuan, China. METHODS: A cohort of 576 AMD patients and 572 healthy controls were enrolled in a case-control study. The SNPs were genotyped by a Mass array MALDI-TOF System. On the premise that the genotype distribution of each SNP locus in both groups satisfied Hardy-Weinberg equilibrium, the genetic pattern was analyzed and the scores of allele and genotype frequencies ware compared. RESULTS: There was a significant association between TNFRSF10A rs13278062 and AMD under the heterozygous model (P = 0.000, OR = 1.529, 95%CI = 1.196-1.954) and the dominant model (P = 0.002, OR = 1.459, 95%CI = 1.154-1.865), suggesting that subjects carrying rs13278062GT and rs13278062TT + GT are more likely to develop the AMD, whereas no significant difference was observed for rs13278062 under other models. No association was detected with the other six SNPs and AMD under various genetic models. CONCLUSION This case-control association study has indicated that TNFRSF10A rs13278062 is associated with AMD under the heterozygous and dominant models, suggesting that the TNFRSF10A variant may be involved in the development of AMD among ethnic Han Chinese population.

Background: Gastric cancer is one of the common gastrointestinal malignancies. Early diagnosis can reduce the mortality rate significantly. In the Chinese consensus published in 2017, the New Gastric Cancer Screening Scoring System was recommended to be used for risk stratification of gastric cancer. Aims: To preliminarily explore the value of the New Gastric Cancer Screening Scoring System in early gastric cancer screening in asymptomatic community population. Methods: At several communities in Suzhou City Xiangcheng District, a questionnaire survey was conducted in asymptomatic community residents willing to accept voluntary serum tests to collect information on high risk factors of gastric cancer. Serum pepsinogen (PG), PGⅡ, gastrin 17 (G-17) and Helicobacter pylori (Hp) IgG were tested simultaneously. Risk stratification of gastric cancer was carried out in accordance with the New Gastric Cancer Screening Scoring System. Gastroscopy was recommended for moderate to high risk individuals. Results: A total of 540 asymptomatic individuals completed the study, of which 11 were categorized as high risk (2.0%), 168 as moderate risk (31.1%), and 361 as low risk (66.9%). Sixty-four moderate to high risk individuals completed the gastroscopy with a response rate of 35.8%. Four precancerous lesions were detected (6.2%), including 3 gastric low-grade intraepithelial neoplasia and 1 duodenal adenoma. No gastric cancer was detected. Conclusions: The New Gastric Cancer Screening Scoring System is useful for risk stratification of gastric cancer in asymptomatic population and may provide a basis for further endoscopic examination. However, the value of this scoring system in low risk areas of gastric cancer needs to be further verified.

Objective:To investigate the clinical manifestations, treatments and prognosis of subacute arsenic poisoning.Methods:In January 2020, a retrospective analysis was carried out on 11 patients hospitalized with subacute arsenic poisoning caused by arsenic contaminated drinking water. We observed manifestations, treatments and prognosis.Results:The main clinical presentations of subacute arsenic poisoningin were gastroenteritis in early phase, some of them had other organ damage, such as skin, blood, liver, kidney, cardiovascular and so on. The later phase was mainly peripheral nervous system damage. The treatment was mainly to chelate arsenic, protect target organs and treat toxic peripheral neuropathy. Most were significantly recoveried, but the recovery of severe toxic peripheral neuropathy was tardy.Conclusion:Acute gastroenteritis is the mainly early manifestation of subacute arsenic poisoning caused by digestive tract, and toxic peripheral neuropathy in the later phase. The prognosis is good, but the recovery of severe toxic peripheral neuropathy is tardy.
