Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective: This study aimed to investigate whether cytokine profiles and virological markers might add value in monitoring the effects of peginterferon (PEG-IFN) therapy for hepatitis B e-antigen (HBeAg) positive chronic hepatitis B (CHB). Methods: HBeAg positive patients with CHB were treated with PEG-IFN for 48 weeks. Clinical biochemical, and HBV serological indexes, as well as cytokines, were detected at baseline and every 12 weeks. Results: A total of 116 patients with CHB were enrolled in this study; 100 patients completed the 48-week treatment and follow-up, of whom 38 achieved serum HBeAg disappearance, 25 achieved HBeAg seroconversion, 37 showed HBsAg decreases ≥ 1 log ₁₀ IU/mL, 9 showed HBsAg disappearance, and 8 became HBsAb positive. The cytokine levels at baseline and during treatment were similar between the HBeAg disappearance group and non-disappearance group. The disappearance of HBeAg was independently associated with HBeAg levels at weeks 12 and 24, and with the HBeAg decline at week 24 ( P < 0.05). The HBsAg response was independently associated with HBsAg, the HBsAg decline, HBeAg, the HBeAg decline at week 12, and HBsAg at week 24 ( P< 0.05). Conclusion There was no significant correlation between the response to interferon (IFN) and cytokines during PEG-IFN treatment. The changes in virological markers predicted the response to IFN after 48 weeks.

Objective: To trace and characterize the whole genome of SARS-CoV-2 of confirmed cases in the outbreak of COVID-19 on July 31, 2021 in Henan Province. Method: Genome-wide sequencing and comparative analysis were performed on positive nucleic acid samples of SARS-CoV-2 from 167 local cases related to the epidemic on July 31, 2021, to analyze the consistency and evolution of the whole genome sequence of virus. Results: Through high-throughput sequencing, a total of 106 cases of SARS-CoV-2 whole genome sequences were obtained. The results of genome analysis showed that the whole genome sequences of 106 cases belonged to the VOC/Delta variant strain (B.1.617.2 clade), and the whole genome sequences of 106 cases were shared with the genomes of 3 imported cases from Myanmar admitted to a hospital in Zhengzhou. On the basis of 45 nucleotide sites, 1-5 nucleotide variation sites were added, and the genome sequence was highly homologous. Conclusion: Combined with the comprehensive analysis of viral genomics, transmission path simulation experiments and epidemiology, it is determined that the local new epidemic in Henan Province is caused by imported cases in the nosocomial area, and the spillover has caused localized infection in the community. At the same time, it spills over to some provincial cities and results in localized clustered epidemics.

BACKGROUND: Various prediction tools have been developed to predict biochemical recurrence (BCR) after radical prostatectomy (RP); however, few of the previous prediction tools used serum prostate-specific antigen (PSA) nadir after RP and maximum tumor diameter (MTD) at the same time. In this study, a nomogram incorporating MTD and PSA nadir was developed to predict BCR-free survival (BCRFS). METHODS: A total of 337 patients who underwent RP between January 2010 and March 2017 were retrospectively enrolled in this study. The maximum diameter of the index lesion was measured on magnetic resonance imaging (MRI). Cox regression analysis was performed to evaluate independent predictors of BCR. A nomogram was subsequently developed for the prediction of BCRFS at 3 and 5 years after RP. Time-dependent receiver operating characteristic (ROC) curve and decision curve analyses were performed to identify the advantage of the new nomogram in comparison with the cancer of the prostate risk assessment post-surgical (CAPRA-S) score. RESULTS: A novel nomogram was developed to predict BCR by including PSA nadir, MTD, Gleason score, surgical margin (SM), and seminal vesicle invasion (SVI), considering these variables were significantly associated with BCR in both univariate and multivariate analyses (P < 0.05). In addition, a basic model including Gleason score, SM, and SVI was developed and used as a control to assess the incremental predictive power of the new model. The concordance index of our model was slightly higher than CAPRA-S model (0.76 vs. 0.70, P = 0.02) and it was significantly higher than that of the basic model (0.76 vs. 0.66, P = 0.001). Time-dependent ROC curve and decision curve analyses also demonstrated the advantages of the new nomogram. CONCLUSIONS PSA nadir after RP and MTD based on MRI before surgery are independent predictors of BCR. By incorporating PSA nadir and MTD into the conventional predictive model, our newly developed nomogram significantly improved the accuracy in predicting BCRFS after RP.

Objective:To observe the effects of traditional Chinese exercise Wuqinxi on balance, walking and quality of life for patients with Parkinson's disease. Methods:From December, 2018 to December, 2020, 62 inpatients with Parkinson's disease in the Affiliated Hospital of Shandong University of Chinese Medicine were randomly divided into control group (n = 31) and observation group (n = 31). The control group received routine medicine and rehabilitation training, while the observation group received Wuqinxi in addition, for eight weeks. The trajectory length and ellipse area of the center of pressure in 30 seconds were measured with PRO-KIN before and after treatment, while they were assessed with Berg Balance Scale (BBS), Timed 'Up and Go' Test (TUGT) and Parkinson's Disease Quality of Life Scale-39 (PDQ-39). Results:The trajectory length and ellipse area of the center of pressure, BBS score, TUGT time, and PDQ-39 score improved in both groups after treatment (t > 11.225, P < 0.001), and all improved more in the observation group than in the control group (t > 5.919, P < 0.001). Conclusions:Wuqinxi training is effective on balance, walking and quality of life for patients with Parkinson's disease.

In order to analyze the expression of genes involved in steroidal saponin biosynthesis pathway in Polygonatum cyrtonema tubers, it is very important to select internal reference genes that are stably expressed at different development stages and in response to abiotic stress. According to the previously established P. cyrtonema transcriptome database and reported internal reference genes in plant, this study systematically analyzed eight candidate internal reference genes including histone H2 A, glyceraldehyde-3-phosphate dehydrogenase, ACTIN, β-tubulin, ubiquitin-conjugating enzyme-E2-10, elongation factor 1-alpha isoform, 18 S rRNA and α-tubulin 4 for expression stability in P. cyrtonema tubers at different development stages and in response to methyl jasmonate(MeJA) stress by using Real time fluorescence quantitative PCR(qPCR). Based on the statistical analysis of qPCR results by using GeNorm, NormFinder and BestKeeper softwares, the expression of ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform are the most stable in P. cyrtonema tubes at different development stages and in response to MeJA stress. The two internal reference genes were further validated by analyzing the expression of 4 genes involved in steroidal saponin biosynthesis pathways. In conclusion, ubiquitin-conjugating enzyme-E2-10 and elongation factor 1-alpha isoform can be used as the most appropriate internal reference genes for qPCR analysis in P. cyrtonema. This study also provide a foundation for future investigate the molecular mechanism of steroidal saponin biosynthesis pathways in P. cyrtonema.

Background:The role of local treatment in oligometastatic prostate cancer (PCa) is gaining interest with the oligometastases hypothesis proposed and the improvement of various surgical methods and techniques.This study aimed to compare the short-term therapeutic outcomes of robotic-assisted laparoscopic radical prostatectomy (RALP) for oligometastatic prostate cancer (OPC) vs.localized PCa using propensity score matching.Methods:Totally 508 consecutive patients underwent RALP as a first-line treatment.The patients were divided into two groups according to oligometastatic state:the OPC group (n =41) or the localized PCa group (n =467).Oligometastatic disease was defined as the presence of two or fewer suspicious lesions.The association between the oligometastatic state and therapeutic outcomes of RALP was evaluated,including biochemical recurrence (BCR) and overall survival (OS).A Cox proportional hazards model was used to assess the possible risk factors for BCR.Results:Totally 41 pairs of patients were matched.The median operative time,the median blood loss,the overall positive surgical margin rate,the median post-operative hospital stays,and the post-operative urinary continence recovery rate between the two groups showed no statistical significance.The 4-year BCR survival rates of the OPC group and localized PCa group were 56.7％ and 60.8％,respectively,without a significant difference (P=0.804).The 5-year OS rates were 96.3％ and 100％,respectively (P =0.326).Additionally,the results of Cox regression showed that oligometastatic state was not an independent risk factor for BCR (P =0.682).Conclusions:Our findings supported the safety and effectiveness of RALP in OPC.Additionally,oligometastatic state and sites did not have an adverse effect on BCR independently.

Objective To observe the clinical efficacy of acupuncture plus intradermal needle in treating mild-to-moderate post-stroke depression (PSD). Method Ninty patients with mild-to-moderate PSD were randomized into group A, B and C, with 30 cases in each group. All the groups were intervened by selecting Baihui (GV20), Shenting (GV24) and Yintang (GV29). Group A received acupuncture plus intradermal needle; group B, intradermal needle alone; group C, acupuncture plus sham acupuncture. Hamilton depression rating scale (HDRS) score and Barthel index (BI) score in the three groups were observed before and at the end of the treatment, and the clinical efficacies of the three groups were compared. Result The HDRS score and BI score showed a significant change after the treatment in the three groups (P<0.01). After the treatment, the HDRS score and BI score in the group A and group B was significantly different from those in group C (P<0.05). The total effective rate was 90.0％ in group A versus 86.7％in group B, and 73.3％ in group C; there was a statistically significant difference between group C and group A or B (P<0.01, P<0.05). Conclusion Both acupuncture plus intradermal needle and intradermal needle alone are effective approaches in treating mild-to-moderate PSD. The treatment efficacy of these two methods is similar.

Objective: In order to investigate the effect of Shufeng Jiedu Capsule (SJC) compatibility on anti-inflammation of pneumonia model rats. SJC whole prescription and its components with effect of heat-clearing and toxin-removing and exterior-releasing were studied. Methods: The pneumonia model of rats induced by Streptococcus pneumoniae was used, divided into control group, model group, cephalexin group, SJC whole prescription group (whole prescription group), SJC exterior-releasing group (exterior-releasing group), and SJC heat-clearing and toxin-removing group (heat clearing and detoxifying group). After administration for 6 d, the colony count of peripheral blood and alveolar lavage fluid (BALF), the number of white blood cell (WBC) and its classification in peripheral blood and alveolar lavage fluid, the contents of nuclear transcription factor-kappa B (NF-κB) and cyclooxygenase (COX-1 and COX-2) were tested to evaluate the compatibility rationality. Results: Compared with model group, the whole prescription group, exterior-releasing group, and heat-clearing and toxin-removing group significantly reduced the colony count of peripheral blood and alveolar lavage fluid, significantly reduced the number of WBC in peripheral blood, significantly increased the proportion of eosinophils and reduced the proportion of basophils. The Q values of rats in the whole prescription group were beyond 1 on two indicators, which were the number of WBC and the proportion of eosinophils. The number of WBC in alveolar lavage fluid and the contents of NF-κB and COX-2 decreased significantly in the whole prescription group, exterior-releasing group and heat-clearing and toxin-removing group. Conclusion: SJC has significant anti-inflammatory effect and therapeutic effect on Streptococcus pneumoniae infection in rats. The exterior-relieving component and the heat-clearing and toxin-removing component have significant synergistic effects.
