Early exercise training after stroke is a therapeutic strategy that has been paid w idespread attention. A series of studies found that early exercise training after stroke can increase expression of neurotrophic factors and maintain the integrity of the blood-brain barrier by inhibiting acute neuroinflammation and apoptosis, and reduce brain damage. This artice reviews the neuroprotective roles of early exercise training after stroke and their possible molecular mechanisms.

Objective:To compare the eradication rate and incidence of adverse reactions between cefuroxime-containing and amoxicillin-containing bismuth quadruple regimen in the treatment of Helicobacter pylori ( H. pylori), and to evaluate the efficacy and safety of cefuroxime in the H. pylori infection patients with positive penicillin skin test results. Methods:From December 2020 to December 2021, a total of 498 patients who received initial H. pylori eradication treatment at the H. pylori Specialized Outpatient Clinic of the First Affiliated Hospital of Soochow University were selected to participate in this prospective cohort study. According to the history of penicillin allergy or positive penicillin skin test results, the patients were divided into amoxicillin group and cefuroxime group. A total of 394 patients were included in the amoxicillin group, and the treatment regimen was esomeprazole 20 mg, bismuth 220 mg, amoxicillin 1 g and clarithromycin 500 mg orally twice a day. A total of 104 patients were included in the cefuroxime group, and the treatment regimen was esomeprazole 20 mg, bismuth 220 mg, cefuroxime 500 mg and clarithromycin 500 mg orally twice a day. The treatment period was 14 days. 13C-urea breath test was conducted during 4 to 8 weeks after the treatment. The eradication rates of the 2 groups were compared by intention-to-treat (ITT) analysis and per-protocol (PP) analysis. The incidence of adverse reactions was compared between the 2 groups. Chi-square test was used for statistical analysis. Results:The results of ITT analysis and PP analysis indicated that the eradication rates of amoxicillin group were 84.3% (332/394, 95% confidence interval (95% CI) 80.6% to 87.6%) and 90.5% (332/367, 95% CI 87.2% to 93.3%), respectively, and the eradication rates of cefuroxime group were 62.5% (65/104, 95% CI 52.7% to 71.7%) and 69.1% (65/94, 95% CI 58.8% to 78.7%), respectively. The eradication rates of amoxicillin group in ITT and PP analysis were both higher than those of cefuroxime group, and the differences were statistically significant ( χ2=24.11 and 28.44, both P<0.001). The incidence of adverse reactions of amoxicillin group and cefuroxime group was 10.9% (43/394) and 14.4% (15/104), respectively, and there was no significant difference ( P>0.05). Conclusion:Cefuroxime and clarithromycin containing bismuth quadruplex regimen failed to achieve a satisfactory eradication rate in patients with H. pylori infection and penicillin allergy.

Objective To analyze the nursing cost effectiveness of non-indwelling bladder catheter in thora-coscopic sublobectomy,and in order to further determine the feasibility of patients undergoing sublobectomy without indwelling catheter.Methods We prospectively collected the clinical data on a total of 254 patients undergoing thoracoscopic sublobectomy in the department of pulmonary surgery of Guangdong Provincial People's Hospital from May 2021 to January 2023.The patients were randomly divided into a study group(128 patients without catheter)and a control group(126 patients with catheter).The nursing cost-effectiveness indexes and postoperative comfort scores were compared between the two groups.Results Seven patients in the experimental group and sixteen patients in the control group needed repeated placement of urinary catheter There were no significant differences in the general demographic and clinical data between the two groups(P>0.05).The cost of materials related to urinary catheter,nursing cost,and total cost in the control group were higher than those in the study group.The total nursing time in the control group was longer than that in the study group.The per capita material cost,nursing cost and total cost in the control group were higher than those in the study group,and the differences were statistically significant(P<0.01).The total score of the comfort scale and the physiological and environmental dimension of postoperative comfort were significantly higher in the study group than in the control group,with statistical significances(P<0.05).Conclusions Thoracoscopic sublobectomy without indwelling bladder catheter can lower medical expense,reduce nursing workload,and improve postoperative comfort.

This paper proposes a new theoretical system for pattern identification of warm diseases , which consists of causal pattern identification and mechanism pattern identification .Mechanism pattern identifi-cation can be further divided into basic mechanism , systematic and symptomatic pattern identification . Basic mechanism of warm diseases arises from conflict ( between healthy and pathogenic qi ) and damage ( to healthy qi ) .Heat is divided into flaming heat and stagnating heat in the former pathogenesis while it is divided into warm heat and damp heat in the latter one .Pattern identification methods such as the De-fense, Qi, Nutrient, and Blood pattern identification and the Triple Energizer pattern identification should be integrated with the basic mechanism and symptomatic pattern identification , so that a more comprehensive theoretical system for pattern identification of warm diseases would be achieved , which would also help its clinical application .

Objective:To analyze the epidemiological and clinical characteristics of patients with brucellosis.Methods:Medical records of confirmed brucellosis patients ( n = 101) were collected from January 2015 to December 2022 at the First Affiliated Hospital of Nanjing Medical University. Patients were divided into acute phase group (≤3 months, n = 89) and non acute phase group (> 3 months, n = 12) according to the course of the disease. The epidemiological characteristics, clinical symptoms, laboratory indicators, treatment plan and curative effect of the patients were analyzed retrospectively. Results:Data of a total of 101 cases of brucellosis were collected, including 72 males and 29 females. The disease occurred throughout the year, with summer (June to August) being the peak period (43.56%, 44/101); 72.28% (73/101) cases had a clear history of contact with animal. Ninety-two point zero eight percent (93/101) of the patients visited the Department of Infectious Diseases for the first time. Clinical manifestations included fever, accounting for 82.18% (83/101), chills accounting for 36.63% (37/101), backache accounting for 33.66% (34/101), night sweats accounting for 22.77% (23/101), and arthralgia accounting for 20.79% (21/101). The symptoms of backache (75.00%, 9/12) and arthralgia (41.67%, 5/12) were more common in patients in the non acute phase group than those of the acute phase group [28.09% (25/89), 17.98% (16/89), P < 0.05]. The most common laboratory test abnormal items were elevated C-reactive protein (CRP, 68.32%, 69/101), erythrocyte sedimentation rate (ESR, 61.39%, 62/101), aspartate aminotransferase (AST, 58.42%, 59/101), and alanine aminotransferase (ALT, 48.51%, 49/101). Elevated ESR (66.29%, 59/89) was more common in patients in the acute phase group than that of the non acute phase group [25.00 (3/12), χ 2 = 7.48, P = 0.006]. All patients were treated with a combination therapy, with a recovery rate of 100.00% (101/101). Conclusions:Brucellosis patients are more common in males, with a higher incidence in summer and often accompanied by a history of contact with animal. The clinical manifestations are diverse and non-specific.

Background: Helicobacter pylori (Hp) is closely associated with peptic ulcer, gastric cancer and other gastrointestinal diseases. Eradication therapy is the main approach to prevent and treat Hp-associated diseases, and patient management is crucial for improving the efficacy of eradication therapy. Aims: To explore the effect of whole-course management on medication adherence and reexamination rate of Hp eradication therapy. Methods: Patients who received Hp eradication therapy in the Hp Specialist Clinic of the First Affiliated Hospital of Soochow University from June 2020 to November 2020 were recruited consecutively. One hundred and twelve patients who received eradication therapy between June 2020 and August 2020 were served as the control group, and 112 patients who received eradication therapy between September 2020 and November 2020 were served as the observation group. Patients in control group were informed only the medication method and reexamination time, while patients in observation group were given the whole-course management composed of informing medication method and reexamination time plus following up online by WeChat and reminding the reexamination by WeChat and by phone. Patients in both groups received a 14-day bismuth quadruple therapy, and were told to undergo

OBJECTIVETo assess whether the dietary supplement (bromelain) has the potential to reduce plasma fibrinogen and other cardiovascular disease (CVD) risk factors in patients with diabetes.

METHODSThis randomized placebo controlled, double blind, parallel design, efficacy study was carried out in China and investigated the effect of 12 weeks of bromelain (1,050 mg/day) on plasma fibrinogen. This randomized controlled trial (RCT) recruited 68 Chinese diabetic patients [32 males and 36 females; Han origin, mean age of 61.26 years (standard deviation (SD), 12.62 years)] with at least one CVD risk factor. Patients were randomized into either bromelain or placebo group. While bromelain group received bromelain capsule, the placebo group received placebo capsule which consisted inert ingredient and has no treatment effect. Subjects were required to take 1,050 mg (3×350 mg) of either bromelain or starch-filled placebo capsules, two to be taken (2×350 mg) after breakfast and another (350 mg) after dinner, daily for 12 weeks. Plasma fibrinogen, CVD risk factors and anthropometric indicators were determined at baseline and at 12 weeks.

RESULTSThe change in the fibrinogen level in the bromelain group at the end of the study showed a mean reduction of 0.13 g/L (standard deviation (SD) 0.86g/L) compared with the mean reduction of 0.36 g/L (SD 0.96 g/L) for the placebo group. However, there was no significant difference in the mean change in fibrinogen between the placebo and bromelain groups (mean difference=0.23g/L (SD 0.22 g/L), =0.291). Similarly, the difference in mean change in other CVD risk factors (blood lipids, blood pressure), blood glucose, C-reactive protein and anthropometric measures between the bromelain and placebo groups was also not statistically significant. Statistical differences in fibrinogen between bromelain and placebo groups before the trial despite randomization may have influenced the results of this study.

CONCLUSIONThis RCT failed to show a beneficial effect in reducing fibrinogen or influencing other selected CVD risk factors but suggests other avenues for subsequent research on bromelain.

The hydrolysis of xylo-oligosaccharides catalyzed by β-xylosidase plays an important role in the degradation of lignocellulose. However, the enzyme is easily inhibited by its catalytic product xylose, which severely limits its application. Based on molecular docking, this paper studied the xylose affinity of Aspergillus niger β-xylosidase An-xyl, which was significantly differentially expressed in the fermentation medium of tea stalks, through cloning, expression and characterization. The synergistic degradation effect of this enzyme and cellulase on lignocellulose in tea stems was investigated. Molecular docking showed that the affinity of An-xyl to xylose was lower than that of Aspergillus oryzae β-xylosidase with poor xylose tolerance. The K_i value of xylose inhibition constant of recombinant-expressed An-xyl was 433.2 mmol/L, higher than that of most β-xylosidases of the GH3 family. The K_m and V_max towards pNPX were 3.6 mmol/L and 10 000 μmol/(min·mL), respectively. The optimum temperature of An-xyl was 65 ℃, the optimum pH was 4.0, 61% of the An-xyl activity could be retained upon treatment at 65 ℃ for 300 min, and 80% of the An-xyl activity could be retained upon treatment at pH 2.0-8.0 for 24 h. The hydrolysis of tea stem by An-xyl and cellulase produced 19.3% and 38.6% higher reducing sugar content at 2 h and 4 h, respectively, than that of using cellulase alone. This study showed that the An-xyl mined from differential expression exhibited high xylose tolerance and higher catalytic activity and stability, and could hydrolyze tea stem lignocellulose synergistically, which enriched the resource of β-xylosidase with high xylose tolerance, thus may facilitate the advanced experimental research and its application.

Rapid detection and response to visual threats are critical for survival in animals. The amygdala (AMY) is hypothesized to be involved in this process, but how it interacts with the visual system to do this remains unclear. By recording flash-evoked potentials simultaneously from the superior colliculus (SC), lateral posterior nucleus of the thalamus, AMY, lateral geniculate nucleus (LGN) and visual cortex, which belong to the cortical and subcortical pathways for visual fear processing, we investigated the temporal relationship between these regions in visual processing in rats. A quick flash-evoked potential (FEP) component was identified in the AMY. This emerged as early as in the LGN and was approximately 25 ms prior to the earliest component recorded in the SC, which was assumed to be an important area in visual fear. This quick P1 component in the AMY was not affected by restraint stress or corticosterone injection, but was diminished by RU38486, a glucocorticoid receptor blocker. By injecting a monosynaptic retrograde AAV tracer into the AMY, we found that it received a direct projection from the retina. These results confirm the existence of a direct connection from the retina to the AMY, that the latency in the AMY to flashes is equivalent to that in the sensory thalamus, and that the response is modulated by glucocorticoids.
