Objective:To explore the effect of handicraft training administered over the Internet on sensation disorders and on the mental status and life quality of stroke survivors.Methods:A total of 75 stroke survivors in the sequelae stage and with sensory disturbance were randomly divided into a general training group of 26 (group A), a handicraft training group of 26 (group B), and a handicraft training group of 23 using Internet instruction (group C). In addition to 40 minutes of routine physical and sensory training rehabilitation every morning, groups A and B were given traditional training and handicraft training, while group C was given handicraft training delivered over the Internet for 40 minutes every afternoon, five days a week for 4 weeks. The traditional training involved inserting wooden boards, plate grinding, as well as sorting beans. The handicraft training involved digital painting, making non-woven flowers, silk screening flowers and paper-rolling. Before and after the 4 weeks of treatment, all of the subjects were assessed using the Fugl-Meyer sensory assessment (FMA-S), the Hamilton Anxiety Scale (HAMA), the Modified Barthel Index (MBI), and the physical component summary scale (PCS) and mental component summary scale (MCS) of the 36-item short-form health survey.Results:After the treatment, significant improvement was observed in their average scores of all three groups in all of the assessments. Groups B and C showed significantly greater improvement in the average FMA-S, HAMA and MBI scores than group A. And the average HAMA and MCS scores of group C were significantly better than those of group B.Conclusion:Handicraft training delivered over the Internet can improve the sensory functioning, mental status and life quality of stroke survivors in the sequelae stage with sensory disturbance.

Objective To identify a novel HLA allele, HLA-B*4086, in Chinese population and to investigate its pedigree. Methods An exceptional reaction pattern was detected in routine HLA typing of a CMDP (China Marrow Donor Programme) sample by PCR-sequence specific oligonucleotide primer (PCR-SSOP) assay. A new HLA-B allele was confirmed by sequence-based typing. Then family investigation was performed. Results DNA sequencing confirmed a new HLA allele. Compared with the closest macthing allele HLA-B*40060101, the novel allele has a difference at nt419 (A→T) in exon 3, which resulted in an amino acid change from Tyr to Phe at codon 140. Family investigation indicated the new allele derives from mother of the carrier. Conclusions One novel HLA allele was confirmed by sequencing based typing and it had been designated as HLA-B*4086 by the WHO Nomenclature Committee. This novel allele was inherited from mother of the carrier.

[Objective]To evaluate the effects of sutureless technique in comparison to conventional techniques for repair of total anomalous pulmonary venous connection(TAPVC)with the method of propensity score analysis.[Methods]From October 2007 to December 2013,179 consecutive patients were enrolled in this study. Patients were operated with sutureless technique(n = 81)or Conventional technique(n=98),and followed up at an interval of 1 month,3 months,6 months and then once a year post-operation. During analysis,three type of propensity-score matching methods,including nearest neighbor caliper matching,Mahalanobis metric matching with propensity score ,optimal full matching were used to create balanced groups of patients receiving each treatment. Surgeons’performance difference was assessed with random frailty proportional hazards models with gamma. Composite endpoints was defined by postoperative death or late death or postoperative pulmonary venous obstruction(PVO),which was evaluated with Kaplan-Meier curve and multivariable Cox proportional hazard model,adjusted by Preoperative-PVO,age,gender,weight and TAPVC type.[Results]Nearest neighbor caliper matching method was the best choice during propensity score analysis. After matching ,sutureless group included 73 patients and Conventional group73 patients. In sutureless group,cardiopulmonary bypass(CPB)time(Z=2.18, P=0.030),cross-clamp time(Z=3.63,P<0.001),rate of composite endpoints(HR 95%CI=0.20(0.06~0.61),P=0.005),late death(HR 95%CI=0.03(0.01~0.55),P=0.017)were significantly better than that in Conventional group. In subgroup analysis ,for patients with pre-PVO,decreased composite endpoints was seen in sutureless group.[Conclusion]Comparison using thepropensity score analysis demonstrated that sutureless strategy for primary repair of TAPVC may associate with decreased mortality rate of post-PVO and CPB time and cross-clamp time.

OBJECTIVETo explore the effect of mild to moderate hypothermia on the expressions of apoptosis-related genes in the brain tissue of rats after cardiopulmonary resuscitation (CPR).
METHODSCPR models were established by asphyxia in 15 male SD rats, which were randomized equally into normal temperature group, 34 degrees celsius hypothermia group and 32 degrees celsius hypothermia group. The brain tissues of the rats were obtained after treatment for 12 h to observe the pathological changes. The expression of caspase-3 in cerebral cortex neurons was determined with immunohistochemistry, and the expressions of Bcl-2 and Bax were detected by Western blotting.
RESULTSCompared with normal temperature group, the two hypothermia groups (especially 32 degrees celsius group) showed significantly decreased expression of caspase-3 in the cortical neurons (P<0.05). Bcl-2 protein expression was significantly increased in the hypothermia groups, especially in 32 degrees celsius hypothermia group (P<0.05). There was no significant difference in Bax protein expression among the 3 groups.
CONCLUSIONMild hypothermia can relieve brain injury by down-regulating caspase-3 expression and up-regulating Bcl-2 protein expression to inhibit apoptosis of the brain neurons. Hypothermia at 32 degrees celsius offers better protection of the brain tissue than hypothermia at 34 degrees celsius.

Objective:To investigate the clinical characteristics, changes in lactate dehydrogenase (LDH) levels, and prognosis in cases of Amanita oberwinklerana poisoning.Methods:A retrospective analysis was conducted on the clinical data of 12 patients who were diagnosed with Amanita oberwinklerana poisoning at Xiangya Changde Hospital between January 2019 and December 2022. The analysis included an assessment of clinical manifestations, renal function changes, LDH levels, and patient prognosis. All statistical analyses were performed using SPSS25.0 Comparisons of ratios between groups were performed using the t test, correlation analyses were performed using scatter diagram and Pearson correlation method, P<0.05 was considered statistically significant. Results:The latency period for symptom onset ranged from 6 to 18 hours, with early symptoms primarily consisting of nausea and vomiting. Three patients developed anuria in the early stage. All patients experienced acute kidney injury (AKI) accompanied by mild liver injury. LDH levels were significantly elevated compared to other types of mushroom poisoning cases ( P < 0.01), with a mean peak value exceeding 2000 U/L. While no correlation was found between LDH levels and kidney injury severity, a positive correlation was observed between LDH levels and length of the course. All 12 patients recovered following dialysis treatment, with recovery periods ranging from 20 to 60 days. No cases of chronic renal failure or mortality were reported. Conclusions:Amanita oberwinklerana poisoning primarily causes acute renal injury. A significant elevation in LDH levels may serve as a potential marker for this type of poisoning. LDH levels did not correlate with kidney injury severity, while positively corrected with the length of the course. All patients in this study achieved good prognosis with full renal recovery.
