ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

Objective To analyze and compare the change of disease burden attributed to high temperature in the Chinese population in 2019 compared with 1990. Methods Based on the global burden of disease study data in 2019, the number of deaths, mortality, disability-adjusted life years (DALY) and DALY rate attributable to high temperature in Chinese population of different ages and genders in 1990 and 2019 were extracted to analyze the changing trend of disease burden attributable to high temperature exposure in Chinese population and its main causes. The Joinpoint regression model was used to analyze the trend of changes in standardized attributable DALY rates. Results Compared with 1990, the number of disease deaths attributable to high temperature in China in 2019 increased from 10 700 to 13 900, and the attributable DALY decreased from 532,200 to 276 100 person-years. The standardized mortality and DALY rates decreased by 35.25% and 65.20%, respectively. The burden attributable to high temperature was higher in males than in females, and the burden was relatively heavier in the population aged 70 and above. In 2019, chronic non-communicable diseases were the main cause of the attributable burden of high temperature exposure, and ischemic heart disease had the highest DALY burden, with an age-standardized DALY rate of 4.64/100 000. Conclusion The absolute death burden attributable to high temperature exposure in Chinese population is still increasing. It is necessary to pay more attention to high-risk groups such as men and the elderly, continue to strengthen environmental protection, and formulate relevant interventions in a targeted way to further reduce the disease burden caused by high temperature exposure.

Objective:To investigate the effect of intraoperative protection of the supraclavicular nerve on the healing of clavicular 1/3 mid-shaft fracture.Methods:A retrospective study was conducted to analyze the 83 patients who had been treated for clavicular 1/3 mid-shaft fractures at Department of Orthopaedics, The First Central Hospital of Baoding from June 2021 to March 2022. There were 57 males and 26 females with an age of (48.1±12.8) years. The patients were divided into 2 groups according to whether the supraclavicular nerve was protected or not during operation. There were 39 cases in the observation group (the supraclavicular nerve was protected during operation) and 44 cases in the control group (the supraclavicular nerve was not protected during operation). The incision length, operation time, intraoperative blood loss, hospital stay, visual analogue scale (VAS) pain scores before operation and 3, 6 and 12 months after operation, fracture healing at 3, 6 and 12 months after operation, and postoperative complications were recorded and compared between the 2 groups. Additionally, the number of microvessels in the middle clavicle was recorded and compared between the affected and healthy sides in 8 patients in the observation group at 6 weeks after operation.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The operation time for the observation group [(72.2±5.4) min] was significantly longer than that for the control group [(61.1±4.7) min]. The VAS scores at postoperative 3 and 6 months for the observation group [2.7 (2.4, 3.1) and 2.1 (1.9, 2.6) points] were significantly lower than those for the control group [3.5 (3.2, 3.8) and 2.7 (2.4, 2.9) points] ( P<0.05). The fracture healing rates at postoperative 3 and 6 months in the observation group [97.4% (38/39) and 100% (39/39)] were significantly higher than those in the control group [81.8% (36/44) and 86.4% (38/44)] ( P<0.05), but there was no significant difference in the fracture healing between the 2 groups at 12 months after operation ( P>0.05). At 6 weeks after operation, the number of microvessels in the middle clavicle was respectively 85.3±0.7 and 87.1±0.8 in the 8 patients in the observation group, showing no significant difference ( P>0.05). After operation, delayed incision healing occurred in 3 cases in the observation group and in 4 cases in the control group, and abnormal sensation of the skin around the incision occurred in 9 cases in the observation group and in 26 cases in the control group, showing a significant difference between the 2 groups ( P<0.05). Conclusion:Intraoperative protection of the supra-clavicular nerve is beneficial for reduction of early postoperative pain and improvement of early fracture healing, and may have a positive effect on the postoperative reconstruction of microvascular network.

A total of 15 patients with allergic rhinitis were interviewed semi structurally, and the results were analyzed by thematic analysis.Results:The experience of the health education accurately linking system was refined into three themes, namely, the practicality of the health education content, the effectiveness of the health education form, and the shortcomings of the education content and form.Conclusions:Through the health education accurately linking system as the carrier, the system presents standardized health education knowledge as the core of clinical application interviews. It is necessary to increase access to health information. The content of propaganda and education can mainly be short videos. The disease knowledge module can be improved according to the severity of the disease, so as to improve the quality of health education and promote the occurrence of health behaviors.

Objective:To evaluate the left ventricular myocardial work parameters of the animal models with left bundle branch block (LBBB) and evaluate the effects of LBBB on left ventricular function and motion pattern by pressure-strain loops (PSL) of speckle tracking imaging (STI).Methods:In Twenty-four healthy male beagles, LBBB was induced by radio frequency ablation under anesthesia, and blood pressure was measured at the same time. Electrocardiograms and echocardiography images were acquired before (baseline), 30 minutes after (acute-LBBB) and 3 months after(chronic-LBBB) the creation of LBBB respectively. STI was applied to measure the left ventricular global longitudinal strain (GLS) and obtain the the PSL of each time point to evaluate the left ventricular global and segmental myocardial work parameters.Results:Compared to the baseline, the global work efficiencies(GWE) were obviously reduced ( P<0.05) and global wasted works(GWW) were significantly increased ( P<0.01) in the acute-LBBB and chronic-LBBB, significant differences were observed in GLS between acute-LBBB and baseline( P=0.04). In baseline, the work efficiency (WEsept) and the constructive work (CWsept) in the basal and middle segments of the septal wall were both obviously higher than the corresponding segments of left ventricular lateral wall( P<0.01), while the distribution of the wasted work(WWsept) was opposite( P<0.01). In acute-LBBB, the WEsept of all segments were significantly decreased ( P<0.05), the WWsept were obviously increased( P<0.05), the CWsept of basal segment was significantly reduced( P=0.01), while the wasted work in the basal segment of lateral wall(WWlat) was increased( P=0.04) compared with the baseline. Compared with the acute-LBBB, the WEsept of basal and middle segments were mildly recovery( P=0.03) in chronic-LBBB, but were still lower than the baseline ( P=0.001), the changes of the other myocardial work parameters of septal and lateral wall were similar to the acute-LBBB. Conclusions:Both acute-LBBB and chronic-LBBB can lead to the changes of left ventricular global and segmental myocardial work parameters. The myocardial work parameters of left ventricle can quantitatively analyze the changes of left ventricular function and motion pattern of the LBBB.

Objective: To study the incidence and clinicopathological features of intermediate fibroblastic/myofibroblastic tumors(IF/MFT) in infants and the young children. Methods: All available cases with soft tissue tumors in infants and children were retrieved from the files of Women and Children′s Hospital Affiliated to Qingdao University, from January 2012 to December 2017.The incidence rate of IF/MFT was observed.Cases of IF/MFT were identified and investigated by light microscopy and immunohistochemistry by reviewing the related literature. Results: Among 290 soft tissue tumors, 15 cases(5.2%) were IF/MFT, accounted for 88.2%(15/17 cases) of borderline soft tissue tumors.Twelve cases were male, 3 cases were female, the median age was 8 months, and 4 cases were congenital.Clinically, 11 cases were presented with slow-growing painless masses located in the trunk or extremities.According to histopathology, 9 cases(60.0%) were categorized as infantile fibromatosis(IFM), including 5 cases(33.3%) desmoid-type and 4 cases(26.7%) diffuse-type; 3 cases(20.0%) as lipofibromatosis(LFM); 2 cases(13.3%) as infantile fibrosarcoma(IFS) and 1 case(6.7%) as giant cell fibroblastoma(GCF). All 15 tumors were characterized by the presence of spindle fibroblasts and myofibroblasts with infiltration of the surrounding structures.Immunohistochemically, all the 15 cases were diffusely positive for Vimentin(Vim), but negative for Myogenin, MyoD1, Desmin and S-100.Smooth muscle actin(SMA), β-catenin and Bcl-2 were positive in some cases to a certain degree.The Ki-67 proliferation index was higher in diffuse-type IFM and IFS, the former was 5.0%-20.0%, and the latter was about 20.0%, however, the other cases showed Ki-67 <5.0%.The main clinical treatment was complete or extensive excision. Conclusions IF/MFT accounts for a high proportion of intermediate soft tissue tumors in infants and young children, mostly seen in male children, and IFM and LFM are the main types.The clinical signs and symptoms associated with these tumors are often nonspecific, and their histopathologic manifestations may overlap.The final diagnosis of IF/MFT must depend on the characteristics of age, location, histopathologic changes and immunohistoche-mical findings.

To unravel the genetic mechanisms of disease and physiological traits, it requires comprehensive sequencing analysis of large sample size in Chinese populations. Here, we report the primary results of the Chinese Academy of Sciences Precision Medicine Initiative (CASPMI) project launched by the Chinese Academy of Sciences, including the de novo assembly of a northern Han reference genome (NH1.0) and whole genome analyses of 597 healthy people coming from most areas in China. Given the two existing reference genomes for Han Chinese (YH and HX1) were both from the south, we constructed NH1.0, a new reference genome from a northern individual, by combining the sequencing strategies of PacBio, 10× Genomics, and Bionano mapping. Using this integrated approach, we obtained an N50 scaffold size of 46.63 Mb for the NH1.0 genome and performed a comparative genome analysis of NH1.0 with YH and HX1. In order to generate a genomic variation map of Chinese populations, we performed the whole-genome sequencing of 597 participants and identified 24.85 million (M) single nucleotide variants (SNVs), 3.85 M small indels, and 106,382 structural variations. In the association analysis with collected phenotypes, we found that the T allele of rs1549293 in KAT8 significantly correlated with the waist circumference in northern Han males. Moreover, significant genetic diversity in MTHFR, TCN2, FADS1, and FADS2, which associate with circulating folate, vitamin B12, or lipid metabolism, was observed between northerners and southerners. Especially, for the homocysteine-increasing allele of rs1801133 (MTHFR 677T), we hypothesize that there exists a "comfort" zone for a high frequency of 677T between latitudes of 35-45 degree North. Taken together, our results provide a high-quality northern Han reference genome and novel population-specific data sets of genetic variants for use in the personalized and precision medicine.

Objective: To investigate the value of abnormal expression of HLA-DR on peripheral blood monocytes in evaluating the immune function status, clinical prognosis and severity of patients with hand, foot and mouth disease (HFMD). Methods: From June 2017 to October 2018, 100 cases of mild HFMD, 80 cases of severe HFMD, 32 cases of critical HFMD and 40 healthy children (control group) were recruited in this study. The patients were divided into two groups, lower DR group (DR-L, HLA-DR expression<30%) and normal DR group (DR-N, HLA-DR expression>30%) according to the HLA-DR expression on monocytes. Flow cytometry was used to detect the CD14⁺ monocytes expressing HLA-DR and the absolute count of lymphocyte subsets. Immunoturbidimetry was used to detect the levels of IgG, IgM and IgA in plasma samples. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the levels of IFN-γ and IL-10 in plasma samples. Pediatric critical illness score (PCIS) and the pediatric risk of mortality Ⅲ (PRISM Ⅲ) were used to estimate the severity of HFMD. Results: ① There were significant differences in HLA-DR expression on monocytes among children with mild, severe and critical HFMD (F=47.102, P<0.05). Patients with critical HFMD had the lowest HLA-DR expression (P<0.05). ② The numbers of CD14⁺ monocytes, CD3⁺ T cells, CD4⁺ T cells, CD8⁺ T cells, B cells and NK cells in peripheral blood of the DR-L group were significantly lower than those of the DR-N group and the normal group, especially in patients with severe or critical HFMD (P<0.05). ③ There was no significant difference in the level of IgG, IgA or IgM among the DR-L, DR-N and control groups (P>0.05). ④ Compared with the DR-N group, the DR-L group showed decreased IFN-γ level and increased IL-10 level in plasma (P<0.05). The ratio of IFN-γ/IL-10 of the DR-L group was lower than that of the DR-N group and control group (P<0.05). HLA-DR expression was negatively correlated with the concentration of IL-10 in plasma (r=-0.704, P<0.05), and positively correlated with the IFN-γ/IL-10 ratio (r=0.773, P<0.05). ⑤ Compared with the DR-N group, the DR-L group showed lower PCIS and higher PRISM Ⅲ. HLA-DR expression was positively correlated with PCIS (r=0.715, P=0.00) and negatively correlated with PRISM Ⅲ (r=-0.610, P=0.00). ⑥ The incidence of pulmonary edema, pulmonary hemorrhage and cardiopulmonary failure and the mortality of HFMD patients in the DR-L group were significantly higher than those in the DR-N group (P<0.05). Conclusions Patients with severe or critical HFMD had cellular immune dysfunction and abnormal HLA-DR expression on CD14⁺ monocytes. Assessing the expression of HLA-DR on monocytes could be used to evaluate the cellular immunity of patients with severe or critical HFMD. Lower expression of HLA-DR on CD14⁺ monocytes might be associated with severe HFMD and poor prognosis.
