Objective:To analyze the epidemiological and clinical features of infectious diseases of the central nervous system (CNS).Methods:A cross-sectional study and analysis were conducted to summarize the epidemiological and clinical characteristics of 9 918 patients with CNS infectious diseases, who were diagnosed and treated at 29 hospitals across China from January 1, 2001 to December 31, 2020. Data collected included demographic data, clinical manifestations, health economic indicators, and prognostic outcomes.Results:Among the 9 918 collected cases of CNS infectious diseases, 5 559 were male (56.0%) and 4 359 were female (44.0%), with an onset age of 38 (25, 53) years. Education level: slightly more junior high school education (2 651 cases, 26.7%), and less elementary school education and below (2 181 cases, 22.0%) were found. Occupational distribution: farmers were found predominant (3 215 cases, 32.4%), followed by workers (1 826 cases, 18.4%) and students (1 633 cases, 16.5%). Clinical manifestations: headache (6 074 cases, 61.2%), fever (5 869 cases, 59.2%) and positive meningeal irritation signs (2 273 cases, 22.9%) were the 3 most common clinical manifestations, followed by nausea and (or) vomiting (2 095 cases, 21.1%), impaired consciousness (2 077 cases, 20.9%), psychiatric symptom (1 866 cases, 18.8%) and epilepsy (1 627 cases, 16.4%), etc., and cranial nerve involvement was found in 669 cases (6.7%). Major pathogens included viruses in 6 814 cases (68.7%), Mycobacterium tuberculosis in 1 677 cases (16.9%), common bacteria in 864 cases (8.7%), fungi in 254 cases (2.6%), spirochetes of syphilis in 183 cases (1.8%), parasites in 121 cases (1.2%), and rickettsiae in 5 cases (0.1%). Urban-rural distribution: slightly more cases were found in the countryside (5 418 cases, 54.6%) than in the towns (4 500 cases, 45.4%). Distribution of onset by season: 2 412 cases (24.3%) fell ill in spring, 2 835 cases (28.6%) in summer, 2 187 cases (22.1%) in fall, and 2 484 cases (25.0%) in winter. Health economics: the duration of hospitalization was 15 (8, 27) days, and the cost of hospitalization was 1.53 (0.91, 3.02)×10 000 yuan. Prognosis: 9 531 cases (96.1%) were cured or improved, and 92 cases (0.9%) died. Conclusions:The pathogens responsible for CNS infectious diseases are predominantly viruses. Although the incidence is slightly higher during the summer months, the overall seasonal pattern is not particularly pronounced. These infections are more commonly observed in young and middle-aged males and present with a diverse range of clinical manifestations, contributing to a significant disease burden.

Hair roots induced by Agrobacterium rhizogene produce higher levels of secondary metabolites than non-induced plants, and the enhanced metabolic capacity is driven by the rol gene. We hypothesized that rol genes can be utilized to improve the biosynthesis of tropane alkaloids (TAs) in Atropa belladonna. In this study, the rolC gene from Agrobacterium rhizogene pRiA4 plasmid, driven by a CaMV35S promoter, was overexpressed in A. belladonna. The phenotypes, TAs content and transcriptional expression of key genes in TAs biosynthesis were analyzed in transgenic A. belladonna plants. Results show that transgenic A. belladonna exhibited a well-developed root system, male sterility, higher stamen column length than pistil, early flowering, internode shortening, smaller but more flowers, increased axillary buds and lateral buds, decreased apical dominance, and long and narrow leaves as compared to wild-type plants. Transgenic A. belladonna produced more TAs than wild-type plants, with the content of hyoscyamine, anisodamine and scopolamine reaching 2.58, 3.59 and 15.77-fold that of the control group, respectively. The gene expression of putrescine N-methyltransferase (PMT), tropinone reductase I (TRⅠ) and hyoscyamine 6-β-hydroxylase (H6H), key enzymes in TAs biosynthesis, were up-regulated compared with the control group. The above results indicate that the rolC gene enhances TAs biosynthesis in A. belladonna by up-regulating the expression of key enzymes in the TAs biosynthesis pathway, laying a foundation for genetic manipulation of A. belladonna to increase TAs content by increasing rolC gene expression.

Malocclusion is one of the three most common oral diseases reported by World Health Organization(WHO). In China, its incidence rate is rising. Malocclusion seriously affects the dental and maxillofacial function, facial appearance and growth development of nearly 260 million children in China, and what is more, it affects their physical and mental health development. Malocclusion occurrence is related to genetic and environmental factors. Early treatment of malocclusion can create a good dental and maxillofacial development environment, correct abnormal growth and control the adverse effects of abnormal genetic factors. It can effectively reduce the prevalence of children's malocclusion and enhance their physical and mental health. This is an urgent need from the economic perspective of our society, so it has great practical and social significance. Experts from the project group "standard diagnose and treatment protocols for early orthodontic intervention of malocclusions of children" which initiated by China National Health Institute of Hospital Administration wrote the "China Experts' Consensus on Preventive and Interceptive Orthodontic Treatments of Malocclusions of Children", which aims to guide and popularize the clinical practice, improve the clinical theory and practice level, and accelerate the disciplinary development of early treatment of children's malocclusion in China. The consensus elaborates the harmfulness of malocclusion and the necessity of early treatment, and brings up the principles and fundamental contents. Based on the law of dental and maxillofacial development, this paper puts forward the guiding suggestions of preventive and interceptive treatments in different stages of dental development ranging from fetus to early permanent dentition. It is a systematic project to promote and standardize the early treatment of malocclusion. Through scientific and comprehensive stratified clinical practice and professional training, the clinical system of early treatment of malocclusion in China will eventually be perfected, so as to comprehensively care for children's dental and maxillofacial health, and improve their oral and physical health in China.

This is a case study of a 58-year-old lady with metastatic nasopharyngeal carcinoma (NPC) who suffered a left neck of femur fracture. Unfortunately, there was an unexpected and rapid cancer progression, requiring her goals of care to transit from rehabilitation after her fracture to palliation. The case brings to light the need for family physicians to be poised to manage cancer patients at the end of life in the community, and work together with other stakeholders to deliver compassionate and supportive care.

Objective:To investigate the protective effects of Elabela(ELA) on the renal injury of db/db mice and its possible mechanism.Methods:Sixteen eight-week-old male db/db mice were intraperitoneally injected with ELA(5 mg·kg -1·day -1) or equivalent normal saline( n=8) for 8 weeks. Eight age-matched male db/m mice received equivalent normal saline injection as normal control. At the end of the experiment, blood and urine samples were obtained for HbA 1C and urinary albumin/creatinine(ACR) measurements. Immunohistochemistry was used to observe the expression of ELA. Histopathological changes in kidney tissue were observed by HE staining and Masson staining. The levels of collagen type Ⅳ(Col-Ⅳ) and transforming growth factor-β1(TGF-β1) as well as Yes-associated protein(YAP) phosphorylation in kidney tissue were examined by western blot. Results:Immunohistochemistry results showed that ELA expression was decreased in the renal tissue of db/db mice as compared with that of db/m mice( P<0.05). After ELA treatment, ACR and blood pressure were markedly decreased in db/db mice( P<0.05), but without significant changes in the body weight and HbA 1C. Renal tubular epithelial cells edema, basement membrane thickening, and increased collagen fiber in db/db were improved by ELA administration. Compared with db/m mice, the levels of TGF-β1 and Col-Ⅳ expression, as well as YAP phosphorylation were significantly increased in renal tissue of db/db mice(0.98±0.08 vs 0.68±0.10, 1.10±0.14 vs 0.51±0.08, 3.38±0.72 vs 0.81±0.13, all P<0.05), which were down-regulated after ELA administration(0.80±0.06, 0.51±0.05, 2.21±0.22, all P<0.05). Conclusion:ELA may improve the renal injury of db/db mice by regulating the signaling pathway of YAP, thereby delaying the development of diabetic nephropathy.

OBJECTIVE: To study the protective mechanism of Chinese medicine Suxiao Jiuxin Pills (, SXJ) on myocardial ischemia and reperfusion (I/R) injury. METHODS: Mouse myocardial I/R injury model was created by 30-min coronary artery occlusion followed by 24-h reperfusion, the mice were then divided into the sham group (n=7), the I/R group (n=13), the tirofiban group (TIR, positive drug treatment, n=9), and the SXJ group (n=11). Infarct size (IS), risk region (RR), and left ventricle (LV) were analyzed with double staining methods. In addition, H9C2 rat cardiomyocytes were cultured with NaSO to simulate I/R in vitro. The phosphorylation of extracellular regulated protein kinases1/2 (ERK1/2), protein kinase B (AKT), glycogen synthase kinase-3β (GSK3β), and protein expression of GATA4 in nucleus were detected with Western blot assay. RESULTS: The ratio of IS/RR in SXJ and TIR groups were lower than that in I/R group (SXJ, 22.4% ±6.6%; TIR, 20.8%±3.3%; vs. I/R, 35.4%±3.7%, P<0.05, respectively). In vitro experiments showed that SXJ increased the NaSO-enhanced phosphorylation of AKT/GSK3β and nuclear expression of GATA4. CONCLUSION SXJ prevents myocardial I/R injury in mice by activating AKT/GSK3β and GATA4 signaling pathways.

OBJECTIVE: To study the effect of low-dose dopamine adjuvant therapy on inflammatory factors and prognosis in preterm infants with necrotizing enterocolitis (NEC). METHODS: A total of 100 preterm infants with NEC from June 2017 to June 2019 were enrolled and divided into a dopamine treatment group and a conventional treatment group using a random number table, with 50 infants in each group. The infants in the conventional treatment group were given symptomatic treatment, and those in the dopamine treatment group were given low-dose dopamine adjuvant therapy in addition to the conventional treatment. ELISA was used to measure the levels of C-reactive protein (CRP), tumor necrosis factor-α (TNF-α), and interleukin-8 (IL-8). The two groups were compared in terms of time to relief of clinical symptoms, fasting time, treatment outcome, prognosis, and adverse reactions. RESULTS: Both groups had significant reductions in the levels of CRP, TNF-α, and IL-8 after treatment, and the dopamine treatment group had significantly lower levels of these markers than the conventional treatment group after treatment (P<0.05). Compared with the conventional treatment group, the dopamine treatment group had significantly shorter time to defecation improvement, time to relief of abdominal distension and diarrhea, and fasting time (P<0.05), a significantly higher response rate (P<0.05), and a significantly lower surgery rate (P<0.05). There were no significant differences in the mortality rate and incidence of adverse events between the two groups (P>0.05). CONCLUSIONS Low-dose dopamine adjuvant therapy can effectively improve the levels of inflammatory factors and clinical symptoms in preterm infants with NEC and has good safety, and therefore, it holds promise for clinical application.

Objective To evaluate the association between preoperative serum thyroglobulin concentration and aggressive behavior of papillary thyroid cancer(PTC).Methods A total of 334 PTC patients diagnosed by surgical pathology treated in our hospital from Jan.2013 to Dec.2017 were retrospectively reviewed.Patients were divided into two groups according to Tg levels and clinicopathological characteristics between the two groups were compared.Binary logistic regression analysis was conducted to evaluate the factors influencing extrathyroidal extension and lymph node metastasis of PTC.Results High level of preoperative serum Tg was signifcantly associated with old age,multifocality,larger maximum tumor size,more frequent extrathyroidal extension,lymph node metastasis,and advanced T and TNM stage(P＜0.05).Maximum tumor diameter ＞2 cm(P=0.031) and preoperative serum Tg level ＞17.21 ng/ml(P=0.028) were independent risk factors for extrathyroidal extension.Maximum tumor diameter ＞2 cm(P=0.007) and preoperative serum Tg levels ＞25.40 ng/ml (P=0.016) were independent risk factors for lymph node metastasis,whereas female was a significant protective predictive factor(P＜0.001).Conclusion Preoperative serum Tg levels may serve as an independent risk marker for extrathyroidal extension and lymph node metastasis of PTC,and partly contributes to predict aggressive behavior of PTC.
