Objective:To explore the curative effect of Penumbra retrograde semi-retrieval Solitaire stents technique in the treatment of acute basilar artery occlusion.Methods:The clinical data of 15 patients with acute basilar artery occlusion in Shengjing Hospital of China Medical University from January 2017 to December 2019 were analyzed retrospectively. All patients were treated with Penumbra retrograde semi-retrieval Solitaire stents technique. The modified thrombolysis in cerebral infarction (mTICI) was used to evaluate the therapeutic effect.Results:Fifteen patients achieved vascular recanalization of occluded basilar artery, and mTICI 2b grade was in 3 cases, 3 grade in 12 cases. One operation completed vascular recanalization in 11 cases, 2 times in 3 cases,3 times in 1 case. CT images 24 to 48 h after operative showed no intracranial hemorrhage. The National Institutes of Health stroke scale (NIHSS) score at discharge was significantly lower than that before surgery: (4.8 ± 2.1) scores vs. (16.1 ± 5.7) scores, and there was statistical difference ( P<0.01). Conclusions:Penumbra retrograde semi-retrieval Solitaire stents technique can improve the efficiency of thrombus grasping and significantly improve patient symptoms.

Objective:
To investigate the trend in incidence of stroke in Nanshan District, Shenzhen City from 2010 to 2021, so as to provide the evidence for formulating the integrated strategy for stroke control.
Methods:
The data of stroke morbidity in Nanshan District from 2010 to 2021 were collected through Shenzhen Chronic Disease Prevention and Control Management System. The incidence of stroke was calculated, and standardized by the population of the Chinese Sixth National Census in 2010. The trends in stroke incidence were evaluated in Nanshan District from 2010 to 2021 using annual percent change (APC) and average annual percent change (AAPC), and gender-, age- and subtype-specific incidence of stroke was descriptively analyzed.
Results:
A total of 30 377 cases with stroke were reported in Nanshan District from 2010 to 2021, with a crude incidence rate of 190.45/105 and a standardized incidence rate of 405.65/105. The crude incidence rate of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021 (APC=5.38%, t=4.678, P=0.001), and a higher crude incidence rate of stroke was seen among men than among women (227.57/105 vs. 148.40/105; χ2=1 309.580, P<0.001). The incidence of stroke appeared a tendency towards a rise with age (χ2trend =435.717, P<0.001), and there was a tendency towards a rise in stroke incidence among residents under 40 years of age (APC=2.89%, t=2.538, P=0.029). The crude incidence of ischemic stroke was 151.24/105, which was higher than that of hemorrhagic stroke (39.21/105) (χ2=10 521.000, P<0.001).
Conclusions
The incidence of stroke appeared a tendency towards a rise in Nanshan District from 2010 to 2021, with ischemic stroke as the predominant subtype of stroke. Males and middle-aged and elderly residents should be given a high priority for stroke prevention and treatment.

Objective:
To investigate the prevalence of current smoking and smoking cessation, and identify the influencing factors among hypertensive patients in Nanshan District, Shenzhen City, so as to provide insights into smoking control among hypertensive patients.
Methods:
The demographic features, life style, status of smoking and smoking cessation in hypertensive patients were collected from 69 community health centers in Nanshan District from 2017 to 2019. The gender- and age-specific prevalence of smoking and smoking cessation was estimated among hypertensive patients, and the factors affecting hypertensive patients' smoking and smoking cessation were identified using a multivariable logistic regression model.
Results:
Totally 4 385 patients with hypertension were enrolled, with a mean age of (58.41±11.19) years, and the participants included 2 265 men (51.65%) and 2 120 women (48.35%). There were 724 current smokers, and the prevalence of current smoking was 16.51%, with 29.71% prevalence in males and 2.41% in females. There were 424 hypertensive patients quitting smoking, and the prevalence of smoking cessation was 36.93%, with 38.20% prevalence in males. Multivariable logistic regression analysis identified male ( OR=12.885, 95%CI: 9.567-17.354 ) and drinking ( OR=2.567, 95%CI: 2.118-3.111 ) as facilitating factors for current smoking among hypertensive patients, and increasing age (OR=0.723, 95%CI: 0.642-0.815) and high exercise frequency (OR=0.881, 95%CI: 0.817-0.950) as barrier factors, while male ( OR=7.309, 95%CI: 3.304-16.165), increasing age ( OR=1.381, 95%CI: 1.120-1.703 ), unmarried ( OR=1.819, 95%CI: 1.329-2.490 ), divorced ( OR=7.837, 95%CI: 1.254-48.975 ), retired ( OR=1.545, 95%CI: 1.095-2.180 ), unemployed (OR=1.801, 95%CI: 1.057-3.066), and high exercise frequency ( OR=1.221, 95%CI: 1.096-1.360 ) were identified as facilitating factors for smoking cessation among hypertensive patients and widowed ( OR=0.285, 95%CI: 0.089-0.906 ), high educational level ( OR=0.766, 95%CI: 0.619-0.949 ), and drinking ( OR=0.488, 95%CI: 0.368-0.647 ) as barrier factors.
Conclusions
The prevalence of smoking is lower, and the prevalence of smoking cessation is higher among hypertensive patients than among general populations in Nanshan District. Young and middle-aged, employed, widowed men with a high educational level are key populations for tobacco control, and alcohol consumption control and intensified exercises are important measures to reduce the prevalence of smoking and improve the prevalence of smoking cessation.

Objective:
To analyze the influencing factors for hospitalization costs among stroke patients with different subtypes, so as to provide the reference for reducing the economic burden of patients.
Methods:
Data of patients with hemorrhagic or ischemic stroke who were discharged from hospitals in Nanshan District, Shenzhen City from January 1, 2016 to December 31, 2021 were collected through Hospital Information System. Hospitalization costs were analyzed between hemorrhagic and ischemic stroke patients, and factors affecting hospitalization costs among stroke patients with different subtypes were identified using a structural equation model.
Results:
A total of 10 298 patients with stroke were recruited, including 2 820 patients with hemorrhagic stroke (27.38%) and 7 478 patients with ischemic stroke (72.62%). The patients with hemorrhagic stroke had a median duration of hospital stay of 19.00 (interquartile range, 18.00) d, and a median hospitalization cost of 26 759.48 (interquartile range, 51 000.87) Yuan. The patients with ischemic stroke had a median duration of hospital stay of 12.00 (interquartile range, 10.00) d, and a median hospitalization cost of 12 199.87 (interquartile range, 13 290.20) Yuan. Structural equation model analysis showed that department of hospitalization, discharge status, ways of leaving hospital, surgery and hypertension had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among hemorrhagic stroke patients, and duration of hospital stay had the highest total effect (0.684), followed by surgery (0.632). Employment status, admission route, department of hospitalization, ways of leaving hospital, payment mode, surgery and dyslipidemia had direct effects on hospitalization costs and indirect effects on hospitalization costs through duration of hospital stay among ischemic stroke patients, and duration of hospital stay (0.746), surgery (0.424) and department of hospitalization (0.151) ranked the top three in total effects.
Conclusion
The hospitalization cost is relatively high among stroke patients in Nanshan District, and duration of hospital stay and surgery have great influence on hospitalization costs among stroke patients with different subtypes.

A magnetic separator was used to separate magnetic bacteria based on their magnetotactic characteristics. Acidithiobacillus ferrooxidans, a bacterium that could synthesize intra-cellular nanometer magnetic particles, was investigated as an example. Strong magnetic and weak magnetic cells were separated and collected. On average, the number of the magnetic particles present in the strong magnetic cells is more than that of the weak magnetic cells. Moreover, semisolid-plate magnetophoresis showed that the magnetotaxis of strong magnetic cells was stronger than the weak magnetic cells. These results suggest that the magnetic separator can be used to isolate the magnetic bacteria, which will facilitate the research of magnetic bacteria.

OBJECTIVEThe aim of this study was to evaluate the effect of postoperative adjuvant therapy on the survival in patients with N1 lymph node metastasis of esophageal squamous cell carcinoma (ESCC).
METHODS110 patients with positive N1 lymph node metastasis of esophageal squamous carcinoma were included in this study. The surgery group included 46 cases and the postoperative adjuvant therapy group included 64 cases (24 cases in the adjuvant chemotherapy subgroup and 40 cases in the adjuvant concurrent chemoradiotherapy). The disease-free survival (DFS) and overall survival (OS) of the two groups were compared and the prognostic factors were analyzed by multivariate Cox model.
RESULTSIn the postoperative adjuvant therapy group, the DFS (16.8 months) and OS (21.3 months) were significantly prolonged compared with those in the surgery group (10.6 months, P=0.007) and (13.7 months, P=0.001), respectively. Postoperative adjuvant chemotherapy significantly extended the OS (31.1 months) of N1-positive patients compared with 13.7 months (P=0.002) in the surgery group. But there were no significant differences between the DFS in the two subgroups (16.3 and 16.8 months, P=0.346) and between the OS (23.4 and 21.3 months, P=0.491). Postoperative adjuvant therapy was an independent prognostic factor in the ESCC patients with N1 lymph node metastasis.
CONCLUSIONPostoperative adjuvant therapy can improve the prognosis and prolong the survival time in ESCC patients with positive N1 lymph node metastasis.

OBJECTIVE:To study the effect s of Bifidobacterium combined with L-carnitine on intestinal flora of dysbacteriosis diarrhea model rats. METHODS :Totally 30 SD rats were randomly divided into blank control group ,model group ,probiotics group(Bifidobacterium triple viable enteric coated capsules 70 mg/mL),L-carnitine group (L-carnitine injection 50 mg/mL)and L-carnitine+probiotics group (L-carnitine injection 50 mg/mL+Bifidobacterium triple viable enteric coated capsules 70 mg/mL). Except for blank control group ,the rats in other groups were given 50 mg/mL clindamycin phosphate intragastrically (2 mL/rat, once a day ,for 4 consecutive days )to establish the model of dysbacteriosis diarrhea. On the 5th day of the experiment ,the rats in administration groups were given corresponding drugs intragastrically ,blank control group and model group were given equal volume of normal saline intragastrically ;with the dosage volume of 1 mL/rat,once a day ,for consecutive 7 days. The general situation of rats in each group was observed during the experiment. The feces of normal control group and model group at the end of the modeling and the feces of the rats in administration group after the last administration were collected for genomic DNA extraction,polymerase chain reaction amplification ,library construction and high-throughput sequencing. After processing ,the effective data were analyzed by operational taxonomic unitsclustering and species annotation ,as well as Alpha and Beta diversity of compared with blank control group ,grade 1 feces and grade 2feces were found in model group. The diversity and richness of intestinal flora ,the ratio of Firmicutes/Bacteroidetes and zhongjuanwang7@163.com the abundance of probiotics such as Lactobacillus, Bifidobacterium and Ackermann were significantly decreased (P<0.05),while the abundance of pathogenic bacteria such as Enterococcus was significantly increased (P<0.05). At the end of the recovery period ,compared with model group ,the activity,fecal morphology and color of rats in probiotics group ,L-carnitine group and L-carnitine+probiotics group returned to normal,and the diversity and richness of intestinal flora had no significant difference (P>0.05). However ,the abundance of Lactobacillus in intestinal tract was increased to a certain extent ,and the abundance of Ackermann in intestinal tract of rats in L-carnitine+probiotics group was significantly increased (P<0.05). CONCLUSIONS :Although Bifidobacterium combined with L-carnitine have no significant effect on improving the diversity and richness of intestinal flora in dysbacteriosis diarrhea model rats,it could increase the abundance of probiotics to a certain extent.

ObjectiveTo analyze the incidence, recovery rate and associated factors of nonalcoholic fatty liver disease (NAFLD) among residents aged 65 years old and above in Xinqiao Community of Songjiang, Shanghai, and to provide basic data for further efficient community management. MethodsData of annual geriatric physical examination program for residents aged 65 and above were collected in Xinqiao Community, Songjiang from 2016 to 2022. Those residents who participated twice or more were included in this analysis. Data were collated into longitudinal form. For each participant, data of the first physical examination was used as baseline, and each subsequent examination was taken as follow-up. Incidence and recovery rate of NAFLD were calculated. Cox proportional hazard models were used to explore the associated factors and their changes with the onset and recovery of NAFLD. ResultsDuring the study period, a total of 11 983 residents participated in physical examinations, of which 8 644 participated twice or more, and 8 154 had no history of excessive alcohol consumption. B-ultrasound showed that there were 5 267 residents without NAFLD and 2 887 with NAFLD at baseline. After a median follow-up of 3.3 years, the incidence density of NAFLD in this population was estimated to be 11.5 per 100 person-years, and the recovery density was 23.4 per 100 person-years. The incidence density of NAFLD was negatively associated with age, and positively associated with baseline BMI, abdominal obesity, high fasting blood glucose, and high triglycerides. The recovery density was negatively associated with baseline BMI and abdominal obesity. Compared with those with normal BMI at both baseline and follow-up, those with persistent obesity showed the highest risk of NAFLD (males: HR: 3.19, 95%CI: 2.16-4.70; females: HR: 3.34, 95%CI: 2.46-4.54) and the lowest potential of recovery (males: HR: 0.58, 95%CI: 0.42-0.82; females: HR: 0.58, 95%CI: 0.44-0.77). Persistently high triglycerides were also associated with a higher risk of developing the disease. ConclusionResidents aged 65 years old and above in Xinqiao, Shanghai had a higher incidence and recovery rate of NAFLD. Women, being obese and having hyperlipidemia are at a higher risk for the development and persistence of NAFLD.
