Objective　To analyze the current status of influenza in Inner Mongolia Autonomous Region and provide targeted measures for the prevention and control of influenza in the entire region. Methods　We collected data on influenza cases reported in Inner Mongolia Autonomous Region from the "Disease Monitoring Information Report Management System" of the China Disease Prevention and Control Information System from 2018 to 2022. Statistical analysis was performed using IBM SPSS 22.0, and the comparative differences were assessed using the χ2 test. ArcGIS 10.5 was used to create thematic maps. In this study, SaTScan 9.5 was used for spatiotemporal scanning analysis of influenza incidence data in the entire region from 2018 to 2022, conducting retrospective spatiotemporal reordering scans. Results From 2018 to 2022, a total of 25 485 cases of influenza were documented in Inner Mongolia, with the highest number of cases reported in 2019 (9 933 cases). Cases were reported throughout the year, with a peak season occurring in the winter and early spring of the following year. There were 13 538 cases in males and 11 947 cases in females, with a male-to-female ratio of 1.13:1, indicating a higher incidence rate in males. Cases were mainly concentrated in individuals under the age of 20, especially in the age group of 0 to 10 years, There were significant differences in influenza incidence rates among different regions and years, showing alternate patterns of prevalence. Retrospective spatiotemporal scanning analysis of influenza cases in Inner Mongolia Autonomous Region from 2018 to 2022 revealed that, in terms of temporal distribution, the cluster of cases mainly occurred in November to December each year and in January of the following year. During the influenza season, cases exhibited significant spatiotemporal clustering in the region. Conclusions　The number of reported influenza cases in Inner Mongolia Autonomous Region varied from year to year but there was no increasing trend over time. Children under 10 years old were the primary susceptible population, and influenza exhibited significant seasonal variation and spatiotemporal clustering. It is recommended to strengthen public awareness and education on influenza prevention and vaccination before the influenza season each year, develop good hygiene habits, seek medical attention early when symptoms occur, and reduce the risk of clustered influenza outbreaks.

Two cases of nevus of Ota resistant to multiple sessions of Q-switched laser treatment are reported.Both of the patients were females,who developed beige or blue patches on the left side of the face (zygomatic region,cheek)several months after birth.No conjunctiva or sclera was involved.The lesions spread to the left retroauricular region and posterior neck during pregnancy in one patient.Histopathological examination of the lesions showed scattered melanocytes and melanophages in lower dermis and subcutaneous adipose tissue as well as apparent proliferation of collagen.Immunostaining for CD34 showed no abnormality in the distribution of vascular endothelial cells in these tissues.No obvious improvement was observed in either of the patient after more than 10 sessions(12 sessions in 1 case,and 13 sessions in the other case)of treatments with Q-switched alexandrite(755 nm)or Q-switched Nd:YAG laser(1064 nm).The immediate response of lesions to laser irradiation was unusual.Purpura or errhysis was absent in the lesions after repetitive irradiation with high-energy laser,but both were visible in the adjacent normal skin even after irradiation with low-energy laser.

Objective:To study the feasibility of using the bionic technology to construct small-caliber vascular prostheses with modified SIS.Methods: The vascular endothelial cells and smooth muscle cells were separated from canine saphenous artery,the cells blended with collagen gel,which were planted respectively on the SIS films,these films were rolled into the biologic three-layer prostheses around a 3mm diameter polyethylene tube;one-layer prostheses without these cells and collagen gel served as control.These 2 types of prostheses were implanted into the defect of bilateral canine femoral by anastomosis in 15 dogs.doppler colour ultrasonic,histology detection and electron microscope examination were done postoperatively.Results: By 12 weeks postoperatively,14 biologic vascular prostheses had kept well patency,the patency rate being 93.3%,the biologic structure like blood vessels had formed,the inner surface of the vessels had been covered with full endothelial cells,a lot of smooth muscle cells had been found in the media of vascular walls in regular line;the patency rate in control group was 60.0%,the endothelial cell coverage was incomplete.Conclusions: The bionic vascular prostheses showed potent blood compatibility,which could keep long-term patency in vivo.Curative effect of repairing the small-caliber vessel defect was well satisfactory.

Background Plasticity of visual system is one of the mechanisms of deprivation amblyopia.Our previous study showed that synapsin plays a role during visual developmental plasticity,and conventional protein kinase C-γ (cPKC-γ) probably is one of upstream kinases of synapsin.However,whether or how the cPKC-γ plays its effects on visual developmental plasticity is below understood.Objective This study was to investigate the dynamic expression of cPKC-γ in visual cortex of normal mice and explore the effects of abnormal visual experience on cPKC-γ expression.Methods The bilateral visual cortex tissues were obtained from 36 clean C57BL/6 mice at postnatal (P) 7,14,21,28,35,42 days respectively and 6 mice for each for the researching of cPKC-γ dynamical expression in visual cortex over aging.Other 24 C57BL/6 mice were randomized into developmental phase group and adult phase group,12 for each group.The monocular deprived (MD) models were established by suturing the upper and inferior eyelides in P14 mice for 14 days in 6 mice in the developmental phase group and 6 healthy mice served as controls,and MD models were established in the same way in 6 P60 mice in the adult phase group,and the same aged mice (6 mice) were used as controls.The mice were sacrificed and bilateral visual cortexes were obtained.The expression of cPKC-γ protein in the visual cortex was quantitatively detected using Western blot assay.The study protocol was approved by Ethic Committee of Tongren Eye Hospital.The use and care of the experimental mice followed the ARVO Statement.Results The cPKC-γ protein was faintly expressed in visual cortex in normal P7 mice,with the related expressing level of (39.74± 11.22)％ and (40.78± 10.37)％ in the left and right cortex,respectively.The expressing level of cPKC-γ protein was gradually increased over aging,with the peak value of (138.68±15.73)％ and (138.47±23.48)％ in P21 mice.A significant difference was found in the expression of cPKC-γ protein in various ages of mice (Fage =57.174,P =0.000),and the expression of cPKC-γ protein was not significantly different between the left and right visual cortexses (Flateral =0.059,P =0.809).No significant differences were found in the expression of cPKC-γ protein on bilateral visual cortexes among the mice of the developmental phase group and adult phase group (Fage =1.798,P =0.159) or among the MD group and normal control group (Fgroup =0.104,P=0.749).Conclusions The dynamic expression of cPKC-γ in the visual cortex of normal mice presents a consistant tend with the aging and development of visual critical period.MD does not affect the expression of cPKC-γ protein in bilateral visual cortexes.Further researches should be performed in the activity of cPKC-γ protein in MD mice.

The changes of interstitial cells of Cajal(ICC)distribution and connexin 43(Cx43)expression in gastric muscle layers were assayed in gastroparesis models of streptozotocin-induced diabetic rats.The results showed that gastric emptying was significantly delayed,the contraction frequency and amplitude of gastric muscle segments were greatly decreased,Cx43 gray values were significantly increased and Cx43 distributed homogeneously with ICC immunopositivity in the model rats.These changes appear to be related to the pathogenesis of diabetic gastroparesis.

Genuine medicinal materials with special characteristics of Traditional Chinese Medicine (TCM), is recognized as high quality medicine. Both ancient records and modern research considered that the origin is an important reason for the formation of genuine medicinal materials. However, blindly transplanting of genuine medicinal materials has led to the quality decline and counterfeit medicines appeared in production or sale progress, which may increase the risk of accidents in TCM. Frequent accidents emerged in Chinese herbal affects its export. What's more, it is a great threat to the medication safety in TCM clinical. There is an urgent need to implement traceability systems of TCM, which could provide convenient information record and traceability of TCM circulation. This paper reviews a variety of technical methods for genuine medicinal materials traceability, and proposed the establishment of genuine medicinal materials traceability system based on two-dimensional code and network database.

Objective To evaluate the imaging performance and characteristics of peripheral primitive neuroectodermal tumors (pPNET), in order to raise awareness of the disease and the diagnostic accuracy. Methods Thirteen patients with pPNET who confirmed by puncture or pathology were enrolled in this study. The CT and MRI features were retrospectively analyzed. Four patients received simple routine CT examination, and 9 patients had MRI examination based on X-ray, CT examination. Results The part of body involved was more widely.Two patients occurred in the sinuses, 1 patient in the chest wall, 1 patient in the lung, and 3 patients in the abdominal and pelvic(1 patient involved the pelvic floor through the pelvic wall lesions to basins), 1 patient in the spine, and 5 patients located in the extremities. The characteristics of pPNET by CT and MRI in soft tissue of 8 patients showed single large soft tissue mass, and the biggest was 11.2 cm × 10.6 cm. In bonds and joints of 5 patients, CT and MRI showed wide range of soft tissue mass, mixed internal signal/density with obviously uneven enhancement, significant bone destruction and dissolvable osseous changes, and no obvious tumor bone and calcification. Conclusions Each site has its relative imaging characteristics of pPNET. CT and MRI can show lesions involving the scope, internal structure, with or without adjacent tissue invasion and metastasis, and provide guidance for clinical treatment and selecting treatment regimen. But in the end, it depends on the diagnosis of pathological and immunohistochemical examination.
