Objective@#To investigate the activities of daily living and the use of assistive devices among disabled people demanding assistive devices in Jiading Township, Jiading District, Shanghai Municipality, so as to provide the evidence for the implementation of rehabilitation interventions and the selection of assistive devices for the disabled people living in the community.@*Methods@#The disabled people demanding assistive devices were sampled from 17 communities in Jiading Township in January 2020. A face-to-face questionnaire survey was conducted to collect participants'age, gender, type of disability, provision and use of assistive devices. The activities of daily living were evaluated using the Activities of Daily Living Scale, and the difference in the frequency of assistive device use was compared among the disabled people with different activities of daily living.@*Results@#A total of 377 questionnaires were allocated, and 328 valid questionnaires were recovered, with an effective recovery rate of 87.00%. The respondents included 187 men ( 57.01% ) and 141 women (42.99%), and had a mean age of ( 71.78±13.86 ) years. Among all respondents, limb disability was predominant (248 people, 75.61%), and 84.45% (277 people) were provided with assistive devices. Assessment of activities of daily living showed complete self-care in 85 respondents ( 25.91% ), functional decline in 39 respondents ( 11.89% ) and functional dysfunction in 204 respondents ( 62.20% ). The proportion of functional dysfunction was predominantly detected among disabled people at ages of 80 years and older ( 79.63% ) ( P<0.05 ). Of the disabled people with assistive devices, 139 people used the devices daily ( 50.18% ), and the proportion of daily use of assistive devices was significantly higher in people with functional dysfunctions than in those with complete self-care ( 59.33% vs. 29.41%; P<0.05 ). In addition, no need was identified as the predominant cause of non-provision of assistive devices ( 29 people, 56.86% ). @*Conclusions@#Functional dysfunction of daily living is highly prevalent among the disabled people demanding assistive devices in Jiading Township, in whom the elderly are predominant, and the proportion of assistive device use is high among people with functional dysfunctions. The provision of assistive devices recommends to be improved based on assessment of activities of daily living.

Objective@#To investigate the origin of infection and risk factors of a case with SARS-CoV-2 infection associated with overseas countries in the Ningbo-Zhoushan Port, Zhejiang Province, so as to provide the evidence for improving the COVID-19 control measures at ports.@*Methods@#Ningbo Center for Disease Control and Prevention ( CDC ) and Beilun CDC conducted case finding and epidemiological surveys immediately after being informed. The general information, history of vaccination and the travel during the latest 14 days were collected from the positive case, and all close contacts were tracked. Saliva samples were collected for SARS-CoV-2 nucleic acid testing and whole-genome sequencing, and the sequencing results were aligned with the GISAID's EpiCoV database. The origin of infection and transmission route of the positive case was investigated.@*Results@#A case was identified positive for SARS-CoV-2 nucleic acid during company M's routine screening in the Ningbo-Zhoushan Port on August 10, 2021, and was confirmed positive for SARS-CoV-2 nucleic acid by Beilun CDC and Ningbo CDC on August 11. Whole-genome sequencing showed SARS-CoV-2 B.1.617.2 ( Delta ) variant, which shared the highest homology with the virus sequence uploaded by Russia on June, 2021 ( Russia/MOW-RII-MH27356S/2021 ). The case was a bundling worker for overseas container ships, and reported communicated with foreign boatmen and contacted materials without protected interventions on the SINOKOR AKITA Container Ship between August 4 and 5, 2021. This ship anchored at Vladivostok, Russia from July 27 to 29, anchored at Ningbo Harbor on August 4, and departed on August 5. Then, 11 boatmen from this ship were tested positive for SARS-CoV-2 nucleic acid on August 8. One asymptomatic case was reported in this epidemic; 254 close contacts and 617 secondary close contacts were identified, and all were tested negative for SARS-CoV-2 nucleic acid. No new cases with SARS-CoV-2 infections were detected until August 25, 2021, and the emergency response was therefore terminated.@*Conclusions@#The infection was a sporadic COVID-19 epidemic associated with overseas countries, which was caused by Delta variant infection through contacts with foreign boatmen or materials by a bundling worker in Ningbo-Zhoushan Port; fortunately, no epidemic spread occurred. Intensified closed-loop management and increased frequency of SARS-CoV-2 nucleic acid test among high-risk populations, and improving the precision and rapid emergency treatment of COVID-19 epidemics are required for the containment of COVID-19 at ports.

Objective@#To investigate the expression of phosphoglycerate mutase 1 (PGAM1) in the mouse testis after exposure to single heat stress (SHS).@*METHODS@#We randomly assigned 32 C57 male mice to an SHS (n = 16) and a control group (n = 16), the former bathed in water at 43 ℃ and the latter at 25 ℃ for 15 minutes. At 1 and 7 days after exposure, we harvested the testicular tissue for observation of the morphological changes of testicular cells by HE staining and determination of the location and expression of the PGAM1 protein by immunohistochemistry and Western blot.@*RESULTS@#The testis volume of the mice were reduced significantly, the spermatogenic tubules were disorganized, and the cells were reduced in number after heat stress and basically disappeared after 7 days. Immunohistochemistry showed extensive expression of the PGAM1 protein in the testicular spermatogenic tubules of the SHS-exposed mice, significantly higher than in the control group at 1 day after exposure, which was down-regulated in the testis tissue at 7 days, but still markedly higher than that in the control. Western blot exhibited significantly up-regulated expression of the PGAM1 protein after heat stress compared with that in the control group.@*CONCLUSIONS@#The expression of the PGAM1 protein undergoes dynamic changes in the mouse testis after exposed to single heat stress, which is related to heat stress-induced proliferation and division of testicular spermatogenic cells.

OBJECTIVE: The purpose of this study was to evaluate the effects of Tashinone II A-sulfoacid-natrum on the pain threshold and potential molecular mechanism for neuropathic cancer pain. METHODS: Forty‑five male Balb/c mice were divided into control group model group and experiment group with each 15. The sciatic nerve muscle plexus of experiment and model group were given injection containing S180 sarcoma cell 2 × 106 mL for each mouse. Mice in the experiment group were given Tashinone II A-sulfoacid-natrum 25 mg/kg once a day intraperitoneal injection. Moreover, mice in the control group were given physiological saline 25 mg/kg, once a day intraperitoneal injection. The mechanical withdraw threshold and thermal withdraw latency were recorded before S180 sarcoma cell injection and in the time point of day 3, 6, 9, 12, and 14. After 14 days treatment, the mice were treated to death and the sciatic nerve CX3CR1 and nuclear factor kappa B (NF‑κB) mRNA was tested by quantitative polymerase chain reaction. RESULTS: Compared with control group, the mechanical and thermal pain threshold of experiment group was significant decreased (P < 0.05). However, compared with the model group, the mechanical, and thermal pain threshold of experiment group was significant elevated in time point of day 3, 6, 9, 12, 14 for mechanical pain threshold and day 9, 12 14 for thermal pain threshold (P < 0.05); the pain threshold for the experiment and model group was decreased in the first 9 days and then elevated gradually. Compared with control group, the CX3CR1 and NF‑κB mRNA relative expression in mice sciatic nerve of experiment group was significant elevated (P < 0.05); but compared with model group, the CX3CR1 and NF‑κB mRNA relative expression of experiment group was significant decreased (P < 0.05). CONCLUSION: Tashinone II A-sulfoacid-natrum can elevates the mechanical and thermal pain threshold through inhibiting the NF‑κB in neuropathic cancer pain rat.

To evaluate the safety and efficacy of transrectal high-intensity focused ultrasound (HIFU) in the treatment of benign prostatic hyperplasia (BPH), serial studies were conducted in 150 BPH pa- tients before and 30 min, 1, 2, 6 and 12 month(s) after Sonablate-500TM HIFU treatment. A sili- con-coated indwelling 16F latex catheter was placed during the determination of the therapy zone. Preoperative and postoperative evaluations were made by using the international prostate symptom score (IPSS), quality of life (QOL), uroflowmetric findings and transrectal ultrasound, and incidence of complications. The cystourethrography was done in 23 patients within 1 year postoperatively. The results showed that after HIFU treatment, IPSS and QOL scores were significantly decreased at 1, 2, 6 and 12 month(s) (P<0.01). Maximum urine flow rate (6.0 to 17.2 mL/s, P<0.01), PVR (75.0 to 30.3,P<0.01) and prostatic volume (65.0 to 38.1 mL, P<0.05) were significantly improved 12 months after the operation. Recurrent urinary retention (n=2) and urethrorectal fistula (n=1) occurred at the 15th postoperative day. The duration of the HIFU prostate ablation was 25-90 rain. The mean time for an indwelling catheter was 3-19 days. These data demonstrate that treatment of BPH with Sonab- late-500TM HIFU is safe and effective.

<p><b>OBJECTIVE</b>To investigate the influence of hypoxia induction factor-1alpha (HIF-1alpha) on glycosis of rat myocardial cell under hypoxic condition.</p><p><b>METHODS</b>The myocardial cells of the rats were routinely isolated and cultured. The cells were divided into single hypoxia (H) and HIF-1alpha inhibiting (I) groups. The cells in H group were cultured in glucose-free medium with mixed low-oxygen gas [1% O2, 94% N2 and 5% CO2 (v/v)]. While the cells in I group were cultured with low-oxygen gas after the cell model of low expression of HIF-1alpha protein constructed by RNAi technique. The cells in both groups were all observed before hypoxia (routine culture) and at the time points of 1, 3, 6, 12 and 24 hours of hypoxia. The LA (lactate acid ) content in the supernatant of the culture and the activity of the key enzymes in glycolysis such as hexokinase (HK), phosphofructokinase (PFK) and lactate dehydrogenase (LDH) of both groups of cells were determined at all the time points.</p><p><b>RESULTS</b>(1) After hypoxia, the HK and PFK activities of the rat myocardial cells in H and I groups were obviously increased at the beginning and decreased thereafter when compared with that before hypoxia. While the activities of HK and PFK in H group at 1, 3 and 6 hours after hypoxia were evidently higher than those in I group (P <0.05 or 0.01), and the peak activity of them in H and I groups was 159 +/- 13 U/g vs 133 +/- 55 U/g, and 298 +/- 44 U/g vs 188 +/- 55 U/g, respectively. (2) Compared with normal control (92 +/- 12 U/g), the LDH activity of the cells in H group after hypoxia increased significantly, reaching the peak at 6 hours after hypoxia (2 568 +/- 125 U/g, P < 0. 01), and it decreased thereafter, while that in I group peaked at 3 hours after hypoxia (2125 +/- 126 U/g, P <0.01). The LA content in the culture supernatant in H group increased significantly after hypoxia with the passage of time, while that in I group increased in smaller magnitude (P <0.01).</p><p><b>CONCLUSION</b>High expression of HIF-1alpha in the rat myocardial cells after hypoxia could directly cause continuous enhancement of cell glycolysis, which was beneficial to the protection of myocardial cells under hypoxic condition.</p>
