Objective To explore the role of transforming growth factor (TFG)-? and matrix metalloproteinases(MMPs)in the development of frozen shoulder. Methods Twenty-four patients who underwent shoulder arthroscopy were included,and were divided into frozen shoulder group ( n =12) and control group ( n =12; n =2 for shoulder instability,n =5 for rotator cuff tear and n =5 for subacromial impingement). Joint capsule tissues at the rotator cuff interval were obtained,and the expression of TGF-?,MMP-1,MMP-2,MMP-3,MMP-9 and MMP-12 mRNA and protein was detected by Real-time PCR and Western blotting,respectively. Results The expression of TGF-? mRNA in frozen shoulder group and control group was 3.36?10 4?2.18?10 3 and 1.85?10 4?3.31?10 3,respectively,the expression of TGF-? protein was 1.55?0.33 and 1.13?0.21,respectively,and there were significant differences between these two groups ( P

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.

Kidney injury and decreased chemosensitivity of tumor cells are obstacles with cisplatin (CDDP) chemotherapy. Down-regulation of the organic cation transporter 2 (OCT2) and multidrug resistance-associated protein 2 (MRP2) is a key means to alleviate CDDP-induced kidney injury and increase chemosensitivity. Astragaloside IV (AS IV) is obtained from the well-known traditional Chinese herb Astragalus membranaceus. This study explored the role of AS IV in preventing kidney injury and enhancing the antitumor effect of CDDP by suppressing OCT2 expression in kidney and MRP2 in tumors. This project was reviewed and approved by the Animal Ethics Committee of the First Hospital of Jilin University. The effects of AS IV on CDDP inhibition of tumor growth and promotion of apoptosis were assessed in Lewis lung tumor (LLC)-bearing mice by H&E and TUNEL staining. Kidney injury was assessed by serum biochemical parameters and H&E staining. We used Western blotting and immunohistochemistry assays to detect OCT2 and MRP2 expression in kidney and tumor. The concentration of CDDP in kidney and tumor was measured by HPLC-MS/MS. AS IV enhanced CDDP chemosensitivity by increasing tumor cell apoptosis and slowing tumor growth, and decreased kidney injury as evidenced by lower blood creatinine (Cr) and blood urea nitrogen (BUN). Co-administration of AS IV suppressed MRP2 overexpression induced by CDDP in tumor tissues and may be an important mechanism for enhancing CDDP chemosensitivity. Moreover, AS IV reduced CDDP-induced kidney injury in mice along with suppression of OCT2 expression in kidney. The concentration of CDDP was increased in tumor but decreased in kidney. In total, AS IV not only enhanced the antitumor effect of CDDP by suppressing MRP2 expression in tumor cells, but also decreased kidney injury induced by CDDP. The results provide new insight into the combined use of a chemotherapy drug and natural ingredients to treat cancer.

OBJECTIVETo evaluate the pre-clinical effect of YJ-XCC1Z3 on the treatment of depression with the mice mouse.

METHODYJ-XCC1Z3 was administered at the dose of 405 mg x kg(-1) and 135 mg x kg(-1) to observe the locomotor activity with the mouse locomotor activity recorder apparatus, to observe the effect of YJ-XCC1Z3 on the duration of immohility in the mouse forced swimming test and tail suspension test, to observe the effect of YJ-XCC1Z3 on the body temperature and the metabolism of monoamine neurotransmitters in mouse brain in the mouse model of reserpine induced hypothermia, and to observe the effect of YJ-XCC1 Z3 on the times of 5-HTP induced head-twitches in mice.

RESULTThere were no significant changes in the locomotor activity, but a significant reduction in the immobility time was observed in the mice treated with YJ-XCC1Z3 405 mg x kg(-1) and imipramine in the forced swimming test and the tail suspension test. YJ-XCC1Z3 135 mg x kg(-1) and 405 mg x kg(-1) could improve the range of reserpine induced hypothermia in mice, and the latter could also enhance the times of 5-HTP induced head-twitches in mice. YJ-XCC1Z3 405 mg x kg(-1) and 135 mg x kg(-1) could increase the content of 5-HT and NE and decrease the ratio of 5-HIAA/5-HT in mouse brain, but the dose of 405 mg x kg(-1) could decrease the content of DA. The dose of 405 mg x kg(-1) could increase the content of 5-HIAA and had no obvious effect on the content of HVA and DOPAC.

CONCLUSIONYJ-XCC1Z3 shows potent antidepressant effect by improving the behaviour of the mouse in depression and not inducing hyperlocomotion in the mice. This effect results in the increase of the content of 5-HT and NE in the mouse brain. YJ-XCC1Z3 can decrease the metabolism of 5-HT to effect the content of 5-HT.

OBJECTIVETo investigate the relationship of gut flora and gut-derived endotoxin with minimal hepatic encephalopathy (MHE).

METHODSPatients with hepatitis B virus-related liver cirrhosis (HBV-LC) were screened for MHE using the number connect test-A (NCT-A) and digital symbol test (DST) and divided into the following groups: HBV-LC with (+) MHE (n = 26) and HBV-liver cirrhosis without (-) MHE (n = 25); in addition, one healthy immediate family member of each patient in the HBV-LC + MHE group was enrolled as a control. Each participant provided fecal and blood samples. PCR amplification and 454 pyrosequencing were used to detect bacterial 16S rRNA in feces. Turbidimetric Limulus amebocyte lysate assay was used to detect level of endotoxin in serum. The significance of inter-group differences was assessed by one-way ANOVA or Student's t-test.

RESULTSThe three groups showed different distributions of gut flora. The differences in the microbial communities' members and distributions were related to disease or health status, but not to the patient's genetic makeup or diet. In particular, the HBV-LC + MHE patients showed significantly lower amounts of different bacterial species and abundance of these species than the other two (non-MHE) groups (P less than 0.05). The healthy control family members had a richer diversity of gut flora than their counterparts with HBV-LC + MHE (P less than 0.05). The HBV-LV + MHE patients also had higher serum levels of endotoxin.

CONCLUSIONDevelopment of minimal hepatic encephalopathy in patients with HBV-LC may be related to a gut flora disorder or higher levels of endotoxin in serum.

OBJECTIVETo introduce the procedure of the 1st ray stabilization combined with resection of the lesser metatarsal heads for patient with severe forefoot deformity caused by rheumatoid arthritis (RA) and evaluate the short to mid-term clinical results.

METHODSFrom Oct. 2006 to Aug. 2010,97 patients (129 feet) aged from 36 to 67 years (average 54), with forefoot deformity caused by rheumatoid arthritis were reviwed. There were 88 males and 9 females,65 single lateral involved and 32 bilateral involved, the average duration of disease was 17 years (6 to 32 years). The 1st ray instability and lesser metatarsophalangeal (MTP) joint stiff dislocation were found in all cases. The first ray stabilization combined with resection of the lesser metatarsal head procedure were performed for all cases. The radiographic Hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measurde and the JSSF (Japanese Society for Surgery of the Foot) score were evaluated before operation and every follow up.

RESULTSThe average followed-up was 37 months (6 to 52 months) for all patients except 5 (7 feet) and 1 died for acute cardiac infarction 1 year after operation. The average JSSF score improved from (33.2 +/- 8.2) points preoperative to (67.3 +/- 3.1) points at final followed-up (P < 0.01); the average HVA was corrected from (50.0 +/- 11.8) degrees preoperative to (21.2 +/- 3.2) degrees at final follow up (P < 0.01); the average IMA was corrected from (15.5 +/- 3.6) degrees preoperative to (9.7 +/- 6.6) degrees at final follow up (P < 0.01). MTP joint nonunion was found in 4 feet. A radiographic high density mass was found in the 1st cuneiform bone during 8 to 11 months followed-up in 3 feet; delayed wound healing was happened in 9 feet; MTP joint infection was happened in 2 feet; tarsometatarsal joint infection was happened in 1 foot; lesser MTP joints deformity recurrence were found in 16 feet.

CONCLUSIONThe characters of forefoot with RA in later stage are the 1st ray deformity and instability compound with the lesser toes deformity. The 1st ray stability procedure which include the 1st MTP arthrodesis and the Lapidus procedure can correct the 1st ray deformities and rebuilt its stability. The lesser toes metatarsal head resection is effective in correct their deformity. This combined procedure is reliable. It is suitable for patients with severe Hallux valgus, increased IMA, tarsometatarsal joint instability and the lesser MTP joint stiff dislocation.

Objective:To explore effects and mechanism of resveratrol on apoptosis of vascular smooth muscle cell in diabetic rats. Methods: The mRNA level of monocyte chemoattractant protein 1 (MCP1),macrophage migration inhibitory factor (MIF) and in-terleukin 18 (IL-18) was detected by quantitative real-time reverse transcription PCR (qRT-PCR). Myocardial fibrosis was analyzed by hematoxylin-eosin (HE) staining and Masson staining. Apoptosis was tested by flow cytometry. The expression of Cleaved caspase-3, Cleaved caspase-9,B cell lymphoma 2 (Bcl-2),Bcl-2-associated X protein (Bax),PI3K,p-PI3K,AKT and p-AKT was measured by Western blot. Results: The mRNA levels of MCP1,MIF and IL-18 in STZ-induced diabetic were reduced by resveratrol (P＜0. 05). The aggravation of myocardial fibrosis in STZ-induced diabetic rats was ameliorated by resveratrol. Apoptosis of vascular smooth muscle cell in STZ-induced diabetic rat group was higher than control group (P＜0. 05 ) . Compared with STZ-induced diabetic rat group, apoptosis of vascular smooth muscle cell in STZ+ resveratrol group was decreased (P＜0. 05). What′s more,the expression of Cleaved caspase-3,Cleaved caspase-9 and Bax in STZ-induced diabetic rats were inhibited by resveratrol(P＜0. 05). And the expression of Bcl-2 in STZ-induced diabetic rats was elevated by resveratrol(P＜0. 05). Compared with control group,the rate of p-PI3K/PI3K and p-AKT/AKT in STZ-induced diabetic rat group was decreased (P＜0. 05). The rate of p-PI3K/PI3K and p-AKT/AKT in STZ+ resveratrol group was higher than STZ-induced diabetic rat group ( P＜0. 05). Conclusion: Resveratrol represses apoptosis of vascular smooth muscle cell in STZ-induced diabetic rats through activating of PI3K/AKT signal pathway.
