Objective:To explore the associations of temperature, relative humidity, and their interaction effect with fall risk.Methods:Data on fall cases were collected using the national injury surveillance system from May to September, in 2006-2022 in Hubei Province. Combined with the meteorological and air pollution data, we conducted a time-stratified case-crossover design and used conditional logistic regression models and distributed lag nonlinear models to examine the exposure-response relationships between temperature, humidity, and fall risk. We further divided the low and the high temperature groups and the low and the high relative humidity groups and analyzed the excess risk ( ER) of falls attributed to dry-hot or wet-hot events. Finally, we calculated the additive interactions of temperature and humidity on fall risk. Results:A total of 55 401 fall cases were included. With the increase in temperature and relative humidity decrease, the exposure-response curves of fall showed nonlinear upward trends among all populations. Gender and age differences were found in temperature-fall and relative humidity-fall risk relationships. Compared with wet-non-hot (normal temperature and high relative humidity) events, the ER of fall in dry-hot (high temperature and low relative humidity) events was 14.80% (95% CI: 9.69%- 20.15%), and the ER of wet-hot (high temperature and high relative humidity) events was 9.59% (95% CI: 2.52%-17.13%). However, there was no statistically significant difference between dry-hot and wet-hot events in the fall, and no statistically significant difference between different genders, ages, occupations, and fall occurred place (all P>0.05). No significant synergistic additive interaction was found between temperature and relative humidity on fall risk (relative excess risk due to interaction=-0.08, 95% CI: -0.19-0.02). Conclusions:Higher temperatures and lower relative humidity were associated with increased fall risk. Both dry-hot and wet-hot events had a higher risk of fall, while high temperature and low humidity have no synergistic effect on fall risk.

Thoracic anesthesia with spontaneous respiration represents a form of precision anesthesia meticulously customized to individual patients.Considering the more stringent requirements this anesthesia approach imposes on the regulation of respiratory function,the writing group of the"Consensus of Experts on the Management of Thoracic Anesthesia with Spontaneous Respiration"has formulated elaborate guidelines regarding indications and contraindications,preoperative evaluation,anesthesia implementation,common complications,and treatment strategies.This was accomplished by referencing relevant domestic and international literature and integrating it with actual clinical requirements.The objective is to standardize the rational application of this anesthesia method.

Objective:To explore the method and effect of free thining anterolateral thigh perforator flap (ALTP) in repairing soft tissue defect of scar contracture deformity after hand trauma.Methods:From March, 2015 to August, 2019, 12 patients who suffered scar contracture after hand trauma were repaired with thin ALTP. First, completely resected the scar contracture tissue from the hands and restored the normal bone structure and force line of the hand. The area of hand wound defects were 5.0 cm×6.0 cm-8.0 cm×10.0 cm. The wound was repaired by free ALTP, and the flap was micro-thinned for the first time. The flaps did not carry broad fascia, and the donor sites were directly sutured. The wound healing, the flap appearance, texture, sensation, scarring of the donor area, and functional recovery of the affected hand were observed regularly after surgery. The patients were followed-up by outpatient review and WeChat.Results:All the flaps survived well after the operation. Two cases suffered crisis because hematoma entraps vein cause by bleeding from perforator branch. After surgical exploration, the flaps survived successfully. All 12 flaps were followed-up successfully, including 6 cases reviewed in outpatient clinic, 4 cases followed by WeChat video and 2 cases by telephone consultation. The follow-up time was 3-20 months, with an average of 11 months. The flaps were not bloated, soft, non-pigmented, and beautiful in appearance. Only linear scars remained in the donor sites. The gripp function, palm function, thumb opposition function and finger function of the affected hand were largely restored. According to the TAM method of Upper Limb Function Evaluation of the Chinese Medical Association: 7 cases were excellent, 4 cases were good, and 1 case was fair.Conclusion:The thinning ALTP can be used to repair the scar contracture deformity after hand trauma. It can carry different tissues for 3-dimensional repair. After operation, the flap has a beautiful appearance, the donor site can be closed directly, and the damage of donor site can be reduced. It is an effective method to repair the hand contracture deformity.

Cerebellar malfunction can lead to sleep disturbance such as excessive daytime sleepiness, suggesting that the cerebellum may be involved in regulating sleep and/or wakefulness. However, understanding the features of cerebellar regulation in sleep and wakefulness states requires a detailed characterization of neuronal activity within this area. By performing multiple-unit recordings in mice, we showed that Purkinje cells (PCs) in the cerebellar cortex exhibited increased firing activity prior to the transition from sleep to wakefulness. Notably, the increased PC activity resulted from the inputs of low-frequency non-PC units in the cerebellar cortex. Moreover, the increased PC activity was accompanied by decreased activity in neurons of the deep cerebellar nuclei at the non-rapid eye-movement sleep-wakefulness transition. Our results provide in vivo electrophysiological evidence that the cerebellum has the potential to actively regulate the sleep-wakefulness transition.

Objective: To screen the differentially expressed proteins of saponins in Pulsatillae Radix inhibiting the proliferation and induce apoptosis on NCI-H460 tumor cells based on proteome technology using nano LC-LTQ-Orbitrap-MS/MS, and preliminarily speculate the potential mechanism. Method: NCI-H460, SK-OV-3 and SGC-7901 tumor cells were cultured in vitro. Methylthiazoletetrazolium (MTT) assay was used to detect the inhibitory rate of saponins in Pulsatillae Radix on three tumor cell lines. Effect of saponins in Pulsatillae Radix on apoptosis was analyzed by Annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) staining flow cytometry and 4',6-diamidino-2-phenylindole (DAPI) staining. Apoptosis was analyzed using flow cytometry and DAPI stain. Nano LC-LTQ-Orbitrap-MS/MS was used to investigate the changes in the protein profiles on NCI-H460 cells treated with saponins in Pulsatillae Radix. Proteins exhibiting differential expression were analyzed by DAVID Bioinformatics Resources 6.8 and Kyoto encyclopedia of genes and genomes (KEGG) database. The differentially expressed proteins were verified by Western blot. Result: Saponins in Pulsatillae Radix could inhibit the proliferation of NCI-H460, SK-OV-3 and SGC-7901 tumor cells and induce apoptosis of NCI-H460 tumor cells. Effect of Saponins in Pulsatillae Radix on the proliferation and apoptosis of NCI-H460 tumor cells was mainly related to the regulation of biological function of ribosome, glycolysis/gluconeogenesis and other biological processes. It was possible to induce apoptosis of NCI-H460 tumor cells by interfering mitogen-activated protein kinase (MAPK) signaling pathway and regulating the Caspase pathway. Conclusion: Saponins in Pulsatillae Radix can inhibit the proliferation and induce the apoptosis of NCI-H460 tumor cells, the mechanism may be related to the intervention of MAPK signaling pathway and the regulation of Caspase pathway. These findings are helpful to elucidate the molecular mechanism of the anti-tumor effect of saponins in Pulsatillae Radix.

AIM:To observe the incidence of ocular fundus disease in preschool children examined by non-mydriatic fundus camera and evaluate its effectiveness compared with direct inspection shadow mirror.
METHODS: Three thousand eight hundred and ninety-six preschool children from April 2012 to October 2013 were examined by Topcon TRC-NW300 color fluorescence fundus camera and direct inspection shadow mirror, and images were saved immediately.
RESULTS: Detection rate of non - mydriatic fundus photography was higher than that of direct inspection shadow mirror. In 3 896 cases, 41 eyes were detected abnormal fundus accounting for 1. 05%. The retinal myelinated nerve fibers, morning glory syndrome, retinitis pigmentosa, congenital retinoschisis were common, accounted for 24. 39%, 21. 95%, 14. 63%, 12-20% respectively. The children eye diseases were often accompanied by abnormal vision (68. 30%), ametropia (63. 41%), strabismus (19. 51%).
CONCLUSION:Non-mydriatic fundus photography is a mydriatic method without medicine, so it is easy for preschool children to accept. Image results could directly display the fundus lesions. It shows important significance in the screening for preschool children eye diseases.

OBJECTIVETo identify and investigate clinicopathological features of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 translocations ("double-hit" lymphoma).

METHODSTissue microarray was constructed from formalin-fixed and paraffin-embedded tissue samples of aggressive B cell lymphomas diagnosed between 2009 and 2012, including 129 cases of diffuse large B cell lymphoma (DLBCL), 5 cases of B-cell lymphoma, unclassifiable with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma (BCLU), 7 cases of Burkitt lymphoma and 4 cases of high-grade follicular lymphoma with diffuse large B cell lymphoma component. Interphase fluorescence in-situ hybridization (FISH) was performed with a panel of probes including myc, bcl-2/IgH and bcl-6 to document related gene translocation and copy number changes. Medical record review was performed and follow-up data was recorded.

RESULTSAmong 145 cases, 5 cases (3.4%) of B cell lymphomas with concurrent myc and bcl-2/IgH or bcl-6 rearrangements (double-hit lymphomas) were identified, including 2 cases involving myc and bcl-2 translocations (1 DLBCL and 1 BCLU), and 3 cases involving myc and bcl-6 translocations (all DLBCLs). Three cases with concurrent bcl-2/IgH and bcl-6 translocations were found. Single gene translocations or increase of copy numbers were found in 66 cases, representing 51.2% (66/129) of all de novo DLBCLs. Ki-67 index of the 5 "double-hit" lymphomas ranged from 60% to 100%. Clinical follow-up data were available in 4 of the 5 "double-hit" lymphoma patients, three of whom died within 2 years and 1 patient was alive after 36 months of follow-up.

CONCLUSIONS"Double-hit" B-cell lymphomas are rare and can only be identified by molecular detection. They should not be considered synonymous with BCLU morphologically, and may present entities within other morphological spectra. Most of the patients have a poor prognosis. Further in-depth studies of larger case numbers are required to determine the pathologic and genetic variables of the lesion.
