Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

OBJECTIVE: To analyze the association between exposure to second-hand smoke (SHS) and 23 diseases, categorized into four classifications, among the Chinese population. METHODS: We searched the literature up to June 30, 2021, and eligible studies were identified according to the PECOS format: Participants and Competitors (Chinese population), Exposure (SHS), Outcomes (Disease or Death), and Study design (Case-control or Cohort). RESULTS: In total, 53 studies were selected. The odds ratio (OR) for all types of cancer was 1.79 (1.56-2.05), and for individual cancers was 1.92 (1.42-2.59) for lung cancer, 1.57 (1.40-1.76) for breast cancer, 1.52 (1.12-2.05) for bladder cancer, and 1.37 (1.08-1.73) for liver cancer. The OR for circulatory system diseases was 1.92 (1.29-2.85), with a value of 2.29 (1.26-4.159) for stroke. The OR of respiratory system diseases was 1.76 (1.13-2.74), with a value of 1.82 (1.07-3.11) for childhood asthma. The original ORs were also shown for other diseases. Subgroup analyses were performed for lung and breast cancer. The ORs varied according to time period and were significant during exposure in the household; For lung cancer, the OR was significant in women. CONCLUSION The effect of SHS exposure in China was similar to that in Western countries, but its definition and characterization require further clarification. Studies on the association between SHS exposure and certain diseases with high incidence rates are insufficient.

OBJECTIVE: To observe the clinical effect of electroacupuncture at acupoints of yangming meridians for sarcopenia. METHODS: A total of 60 patients with sarcopenia were randomized into an observation group and a control group, 30 cases in each group. In the control group, conventional nutrition intervention for sarcopenia was adopted. In the observation group, on the basis of the treatment in the control group, acupuncture was applied at bilateral Binao (LI 14), Quchi (LI 11), Zusanli (ST 36), Yanglingquan (GB 34), etc.,ipsilateral Quchi (LI 11) and Zusanli (ST 36) were connected to electroacupuncture, with discontinuous wave, 2 Hz in frequency, 1-10 mA in intensity, 2 times a week, with a interval of 3 days. A total of 12-week treatment was required in the two groups. Before and after treatment, the appendicular skeletal muscle mass index (ASMI), grip strength, 6 m-walking time, body fat percentage and body moisture percentage were observed in the two groups. RESULTS: Compared with those before treatment, after treatment, ASMI and grip strength were increased while 6 m-walking time was shortened in the two groups (P<0.05); body fat percentage was decreased while body moisture percentage was increased in the observation group (P<0.05). After treatment, in the observation group, ASMI, grip strength and body moisture percentage were increased (P<0.05), 6 m-walking time was shortened and body fat percentage was decreased (P<0.05) compared with those in the control group. CONCLUSION Electroacupuncture at acupoints of yangming meridians can effectively improve the skeletal muscle mass, muscle function, body fat percentage and body moisture percentage in patients with sarcopenia, and make the distribution of muscle and fat more reasonable.

OBJECTIVE: No consensus exists on the relative risk ( RR) of lung cancer (LC) attributable to active smoking in China. This study aimed to evaluate the unified RR of LC attributable to active smoking among the Chinese population. METHODS: A systematic literature search of seven databases was conducted to identify studies reporting active smoking among smokers versus nonsmokers in China. Primary articles on LC providing risk estimates with their 95% confidence intervals ( CIs) for "ever" "former" or "current" smokers from China were selected. Meta-analysis was used to estimate the pooled RR of active smoking. RESULTS: Forty-four unique studies were included. Compared with that of nonsmokers, the pooled RR (95% CI) for "ever" "former" and "current" smokers were 3.26 (2.79-3.82), 2.95 (1.71-5.08), and 5.16 (2.58-10.34) among men, 3.18 (2.78-3.63), 2.70 (2.08-3.51), and 4.27 (3.61-5.06) among women, and 2.71 (2.12-3.46), 2.66 (2.45-2.88), and 4.21 (3.25-5.45) in both sexes combined, respectively. CONCLUSION The RR of LC has remained relatively stable (range, 2-6) over the past four decades in China. Early quitting of smoking could reduce the RR to some extent; however, completely refraining from smoking is the best way to avoid its adverse effects.

Objective:To analyze the epidemiological characteristics and genotypes of human rhinovirus (HRV) in patients with upper respiratory tract infection in Qingdao in the winter of 2020.Methods:Throat swab samples were collected from 101 patients with upper respiratory tract infection in Qingdao from November 2020 to January 2021. Quantitative PCR was used to detect 15 common respiratory viruses in the samples. HRV-positive samples were further analyzed with RT-PCR to amplify and sequence HRV VP4/VP2 gene. A phylogenetic tree was constructed based on the sequencing results and homology analysis was conducted.Results:Six common respiratory viruses were detected in the 101 patients. Thirty-four cases (34/101, 33.66%) were single pathogen infection and two cases were multiple infection (2/101, 1.98%). The positive rate of HRV was the highest (21.78%, 22/101). Twenty HRV VP4/VP2 sequences were successfully amplified. Phylogenetic analysis showed that there were 16 strains of HRV-A subtype and four strains of HRV-C subtype and 14 serotypes were involved.Conclusions:HRV was one of the leading viral pathogens causing upper respiratory tract infection in Qingdao in the winter of 2020 and the predominant subtype was HRV-A.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective To investigate whether the protective effects of leonurine (SCM-198) against endotoxin induced uveitis (EIU) of SD rats caused by lipopolysaccharide (LPS) was existing,and discuss the underlying mechanisms.Methods Thirty-six normal healthy male SD rats were divided into 3 groups randomly with the same baseline bodyweight and feeding conditions.All rats received intragastric administration every day.The experimental group was devided into 4 subgroups,rats in these subgroups received SCM-198 intragastric administration by as the dose of 10,20,40 and 80 mg/kg bodyweight per day,rats in the negative control group received intragastric administration of normal saline 10 mL/kg per day,rats in the positive control group received intragastric administration ofdexamethasone (DEX) 0.5 mg/kg bodyweight per day.All rats received a 21-day-intragastric administration.The body weight of all rats was monitored every 7 days.The electroretinogram (ERG) examination was taken in the 18th day.All rats received a 100 mg S.typhi LPS intraperitoneal injection after the 21st intragastric administration.Twenty-four hours later,following anaesthesia,all rats received another ERG examination,and inflammation was scoring under microscope by 2 experienced ophthalmologists,after that the aqueous humor of all rats was collected from the left eye.The aqueous humor was kept in-80 ℃ immediately.Then the rats were sacrificed and the right eyes were immediately enucleated to finish the HE staining and immunohistochemistry (IHC) staining examination of tumor necrosis factor-α (TNF-α) and intercellular cell adhesion molecule-1 (ICAM-1).The total amount of protein in aqueous humor was detected by BCA test.Western blot was used to examine the expression of TNF-α,interleukin-1β (IL-1β),IL-6 and ICAM-1.All data was analyzed by SPSS 19.0,and differences were considered significant at P＜0.05.Results The body weight of the rats in positive control group was significantly lower (P＜0.05) than the experimental group and the negative control group after the 21-day-intragastric administration.The inflammatory score of experimental group was lower than that of the negative control group,but higher than the score of positive control group.The HE staining sections showed the similar results.The a wave of ERG in 0.01 cd of rats received 20 mg/kg SCM-198 daily intragastric administration after LPS injection was significantly lower than that before the LPS injection (P＜0.05),also lower than other groups after LPS injection.The expression of TNF-α,IL-6 and IL-1β in the aqueous humor of the rats in the subgroup of SCM-198 10 mg/kg daily intragastric administration was lower than other groups.Conclusions Intragastric administration of SCM-198 has protective effect against endotoxin induced uveitis in SD rats without obvious adverse reaction,which could alleviate the imflammatory reaction and the damage to the uvea construction.NF-κB plays an important role in the reaction.Thus,SCM-198 is a candidate potent compound with potential therapeutic applications in inflammation associated eye diseases.While the best mode and dose of administration should be further investigated.

This study aimed to clarify preliminarily the effects and mechanisms of Shenkang injection (SKI) promoting extracellular matrix(ECM)degradation via regulating extracellular-signal regulated protein kinase(ERK)1/2/matrix metalloproteinases(MMPs)signaling pathway in renal failure rats. Twenty rats were randomly divided into 4 groups：the Sham group,the Model group,the SKI group and the Enalapril maleate(EM)group. The model rats with renal failure were induced by intragastric administration of adenine and unilateral ureteral obstruction(UUO). After modeling, the rats in SKI group and EM group were intervened by intraperitoneal injection of SKI or intragastric administration of the EM suspension,while the rats in Sham group and Model group were administrated with distilled water respectively for 3 weeks. The 24 h urinary protein excretion(Upro)and urinary N-acety1-β-D-glucosaminidase(UNAG)in all rats were tested after drug administration. All rats were sacrificed after drug administration for 3 weeks,blood and kidney were collected,renal morphological characteristics were observed. Furthermore,serum biochemical indices and the protein expressions of collagen type IV(CIV),MMP-2,MMP-9,tissue inhibitors of metalloproteinase(TIMP)-1,ERK1/2 and phosphorylated-ERK1/2(p-ERK1/2)in the kidney were evaluated respectively. The results indicated that,after the intervention of SKI,serum creatinine(Scr),blood urea nitrogen(BUN),uric acid(UA),albumin(Alb),Upro,UNAG and renal morphological change in model rats were improved at different levels,respectively. Moreover,these actions were similar to EM. In addition to these,SKI adjusted the protein expressions of MMP-2,MMP-9 and TIMP-1,and down-regulated the protein expressions of p-ERK1/2 in the kidney. Moreover,these actions were different from EM. In conclusion,SKI promotes ECM degradation and delays the progression of renal failure possibly through regulating ERK1/2 signaling pathway activation in the kidney and intervening MMPs/TIMP-1 expressions in vivo.
