ABSTRACT

Objective:To observe the effect of extracorporeal shock wave therapy on tendon adhesion in late period after hand tendon repair. Methods:From July, 2017 to December, 2018, 40 patients with tendon adhesion after hand tendon repair more than three months were collected. They were randomly divided into control group (n = 20) and experimental group (n = 20). Two groups received routine therapy, and the experimental group added extracorporeal shock wave therapy. Before and two months after treatment, the total active movement (TAM) of the fingers and the grip strength were messured. Results:There was no significant difference in TAM of the fingers and the grip strength before treatment (P > 0.05). After treatment, TAM of the fingers and the grip strength significantly increased (|t| > 10.284,P < 0.001), and were higher in the experimental group than in the control group (t > 0.386,P < 0.001). Conclusion:Extracorporeal shock wave therapy could facilitate to improve the tendon slippage and hand function in patients with tendon adhesion after hand tendon repair.

ABSTRACT

Object To study the effects of the number of arcs in the treatment of cervical cancer with volumetric modulated arc therapy (VMAT) on the treatment plan, and to provide reference for the selection of the number of arcs in the clinical application.Methods CT images of 10 patients with cervical cancer were selected, it's the radiation therapist that delineated the target area and organs, the prescribed dose was 5040 cGy per 28 times to the target area, and single arc (Arc1), double arc (Arc2) and three (Arc3) plan were designed by RayStation planning system to compare the differences with the dosimetry characteristics of target and organs. The time required for planning optimization was recorded, and the difference between the monitor unit and the delivery time in the three plans was analyzed. A dose validation tool for PTW was used to verify the dose to analyze the influence of the number of arc on the passing rate of gamma verification.Results Single arc plan (Arc1), double arc plan (Arc2) and three arc plan (Arc3) for 10 cases of cervical cancer all proved to meet the clinical requirements. With the increase of arc number, the target area distribution got improved, V40, V45 and Dmean in the organs at risk of rectum, bladder, and femoral head gradually decreased in case of doses of 40 and 45 Gy, and V35, V40 and V45 in the normal tissue were lowered in case of the doses of 35, 40 and 45 Gy. With the increase of the arc number, the optimization time and the delivery time of the plan increased, while the difference between the monitor unit of the three plans was smaller. The passing rate of the three plans was more than 99.5%, and the difference was small.Conclusion Cervical cancer VMAT plan has the target dose distribution and the protection of organs at risk enhanced with the increase of the number of arcs, while the treatment time and cost increased.

ABSTRACT

BACKGROUND: Treatment of orthopedics diseases is largely based on reconstruction to restore the normal structure of the human motor system. However, the human body's ability to repair cannot meet clinical requirements for the treatment of some diseases. In order to solve the problem of tissue regeneration in life science, stem cell therapy has emerged in recent years. OBJECTIVE: To summarize the research progress of stem cells in orthopedics diseases. METHODS: A computer-based search of CNKI, WanFang and PubMed databases was performed for relevant articles concerning stem cell therapy for orthopedics diseases published from 2000 to 2017. Representative and innovative results were analyzed in result analysis. RESULTS AND CONCLUSION: Studies have shown that stem cells have advantages in the treatment of diseases involving the bone, cartilage, spinal cord injury, tendon and ligament injury, and degenerative disc disease. However, further investigations with large sample, long-term follow-up and higher evidence level are warranted. Meanwhile, a good understanding of the natural course of diseases is essential to better utilize stem cell therapy in clinical practice. Combination of stem cell therapy with traditional surgery can achieve better outcomes in patients.

ABSTRACT

·AIM:To determine the effect of anterior-posterior joint surgery on choroidal thickness in patients with proliferative diabetic retinopathy (PDR). · METHODS: A retrospective, case - control study enrolled 60 eyes of 60 patients with PDR diagnosed at Qingdao Municipal Hospital. The patients, who had conditions that warranted anterior - posterior joint surgery,were divided into a clinically significant macular edema group (PDR/CSME+;31 patients,31 eyes) and a non-CSME group (PDR/CSME-;29 patients,29 eyes). Twenty-seven eyes of 27 normal patients were included in the control group. All affected eyes underwent anterior - posterior joint surgery. After surgery, the subfoveal choroidal thickness (SFCT), and the nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT), which were obtained at a distance of 1500μ m from the fovea in the nasal and temporal directions, respectively, were measured in the control and PDR groups by enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) at 1wk,1,3, and 6mo after surgery. Changes in choroidal thickness after anterior - posterior joint surgery were compared between the groups. ·RESULTS:The SFCT,NCT,and TCT were significantly thicker at 1mo than at 1wk, 3, and 6mo after surgery in the PDR/CSME+ and PDR/CSME- groups(P<0.05). The SFCT, NCT, and TCT were significantly thinner at 6mo than at 1wk,1,and 3mo after surgery in the PDR/CSME+and PDR/CSME- groups(P<0.05). The SFCT,NCT,and TCT in the PDR/CSME+ and PDR/CSME- groups at 1wk, 1, and 3mo after surgery were significantly thicker than those in the control group (all P<0.05), but the SFCT, NCT, and TCT at 6mo after surgery showed no significant difference compared with the control group (all P>0.05). There was no significant difference in the SFCT,NCT, or TCT at 1wk, 1, 3, or 6mo between the PDR/CSME+ and PDR/CSME- groups (P>0.05). ·CONCLUSION:The choroidal thickness of PDR patients increases within 1mo after surgery, and decreased after 1mo,but is not significantly different between the control group and the PDR groups at 6mo after surgery. Whether PDR is associated with CSME has no effect on the choroidal thickness after surgery.

ABSTRACT

Objective To investigate the epidemiology characteristics of crawfish related rhabdomyolysis (RM) in Nanjing, 2016.Methods Outpatient and inpatient electronic medical system of 21 hospitals in Nanjing during 2016 were retrospectively searched, and all the patients diagnosed with RM were selected. The patients with none crayfish-related RM was excluded. The epidemiology characteristics were depicted. The geographic information system (GIS) was used to collect, manage and analyze the spatial data, to visualize it, to analyze the spatial distribution features of the disease, and to explore the cause of disease prediction. GeoDa 1.8 software was used to analyze the global and local spatial auto-correlation.Results A total of 1183 patients with crawfish related RM were initially screened, excluding 59 patients with RM caused by trauma, severe exercise, heat stroke, myositis, poisoning, drugs, and genetic diseases, and 1124 patients were enrolled. The proportion of men was 36.48% (410/1124) with an incidence of 12.54/100 thousands; while of women was 63.52% (714/1124) with an incidence of 21.86/100 thousands. The median age at onset was 34 (28, 43) years. From July to August, the incidence of crawfish related RM was the highest, accounting for 96.53% of the total number of cases. The top four incidence areas were Pukou (41.54/100 thousands), Jianye (25.94/100 thousands), Qixia (25.73/100 thousands), Gulou (25.04/100 thousands), all of which were adjacent to the Yangtze River. Global spatial autocorrelation analysis showed: MoranI = 0.427,Z = 2.646,P = 0.003, suggesting that the crawfish related RM had positive spatial autocorrelation. The results showed that the spatial structure of crawfish related RM existed in Nanjing in 2016. Local spatial autocorrelation analysis showed that the high-high concentration areas were Pukou, Jianye and Liuhe. The incidences of above three areas which were the Nanjing section of the lower reaches of the Yangtze River flowed through the region and surrounding areas were higher than the overall incidence of Nanjing.Conclusion The prevalence of crawfish related RM in Nanjing during 2016 had an obvious region-concentrated character and global spatial autocorrelation with the high prevalent regions mainly concentrated in the urban areas adjacent to the Yangtze River.

ABSTRACT

AlM: To silent hypoxia inducible factor-1α ( HlF-1α) gene in malignant melanoma of the choroid cell by small interference RNA ( siRNA ) and investigate its effect on the expression of matrix metalloproteinase-2 ( MMP-2 ) in the choroid cell line human uveal melanoma cell (OCM-1) in hypoxia environment.METHODS:OCM-1 cells cultured on culture flask were divided into normal group and hypoxia group. Hypoxia group were divided into five groups: simple hypoxic group, and interference group, and negative control group, and positive control group, and liposome group. Normal group cells were cultured on DMEM culture flask with 10% FBS, 100U/mL penicillin, 100μg/mL streptomycin as well as high concentration of glucose. The cells were maintained at 37℃ in a humidified 5% CO2 incubator. Cells in good condition were selected for experiment. For hypoxia group, chemical hypoxia inducer CoCl2 was added into nutrient medium at the concentration of 100μmol/L to simulate hypoxia microenvironment. We designed and synthesised siRNA ( siRNA + negative control+positive control ) , the target sequences of the HlF-1α to transfect hypoxic malignant melanoma of the choroid cell. SiRNA including HlF-1α siRNA, β-actin siRNA and negative control group synthesized in vitro transfected hypoxic OCM - 1 cell through Lipofectamine2000. The expression of HlF-1α, MMP-2 gene and the protein were detected by RT-PCR and Western blot. RESULTS: Compared with the normal group, the expression of HlF-1α mRNA was not obviously changed (P>0. 05), but the expression of HlF-1α protein and MMP- 2 mRNA protein was significantly higher ( P0. 05).CONCLUSlON: Hypoxia status may upregulate the HlF-1α in OCM-1 cells by increasing the expression of protein. Hypoxia can also inactivate MMP-2, resulting in upregulation of MMP-2 RNA and the expression of its protein. The expression of HlF-1α and MMP-2 mRNA can be down-upregulated by transfecting OCM-1 with HlF-1α siRNA.

ABSTRACT

Background Neovascular glaucoma (NVG) is a serious ocular disease which may cause blindness.The primary pathogenesis of NVG is ischemic retinopathy derived by central retinal vein occlusion (CRVO) and diabetic retinopathy (DR).Clinical characteristics of NVG are variable based on the difference of primary diseases,such as CRVO and DR.However,there is a few studies regarding the diffcrcnces of NVG initiated by CRVO and DR.Objective This study was to compare the clinical characteristics in NVG patients secondary to CRVO and DR.Methods A series case observational study was carried out in Hiserve Hospital of Qingdao University from January 2009 to June 2012.Twenty-nine eyes of 27 patients with NVG caused by CRVO (10 eyes of 10 patients) and DR (19 eyes of 17 patients) were included.The history of underlying diseases,course of NVG,intraocular pressure(IOP),fundus findings and complications after treatment were analyzed and compared between the CRVO-derived NVG and DR-derived NVG.All patients underwent panretinal photocoagulation,improving microcirculation therapy,anti-glaucoma (drug or surgery) and causative disease treatment,and some of them received vitrectomy or/and cataract surgery.Two eyes from each group received intravitreal injection of ranibizumab.The follow-up time in both groups was (14.00±10.13) months and (17.89±12.52) months,respectively.Results The median time of underlying disease was 3.3 months (2 weeks to 6 months) in the CRVO patients and 11.1 months (4 to 36 mouths) in the DR patients,with a significant difference between them (Z =-2.40,P<0.05).CRVO-derived NVG progress was much faster than that of DR-derived NVG.The number of the eyes with visual acuity improvement after treatment was 2 in the CRVO-derived NVG and 15 in the DR-derived NVG;while the number of the eyes with unchanged or worse visual acuity was 8 and 4 in the CRVO-derived NVG eyes and the DR-derived NVG eyes (x2 =9.38,P<0.01).The difference of IOP in pre-and post-treatment was (37.00±9.91)mmHg in the CRVOderived NVG eyes and (8.92±12.05)mmHg in the DR-derived NVG eyes,showing a significant difference between them (t =6.30,P<0.01).In the CRVO-derived NVG eyes,optic disc edema,retinal hemorrhage,and vein dilatation were seen in 6 eyes,and mild optic disc edema and retinal hemorrhage were observed in 4 eyes.After treatment,fundus could not be seen in 4 eyes,in other 2 eyes optic disc and retinal laser spots were unclearly observed.In addition,pale optic disc and retinal vessel occlusion appeared in 2 eyes,and silver wire-like arteries exhibited in 2 eyes.In pre-treated DR-derived NVG eyes,fundus could not be seen in 8 eyes and Ⅲ-Ⅳv stages of DR findings appeared in 11 eyes.After treatment,retinopathy was stabilized in 16 eyes of 15 cases.Advanced retinopathy(V-Ⅵ stages of DR findings) was revealed in 3 eyes of 3 cases.The incidence of the complication after treatment was 100.0% in the CRVO-derived NVG eyes and 21.1% in the DR-derived NVG eyes (x2=5.18,P<0.05).Conclusions The clinical characteristics of NVG secondary to CRVO and DR are variable,an appropriate treatment option should be selected according to different features of NVG.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinical features, diagnosis, treatment, and prognosis of epithelioid sarcoma (ES).</p><p><b>METHODS</b>The clinical data of 13 cases with epithelioid sarcoma in the Tianjin Medical University Cancer Institute and Hospital from March 1995 to December 2009 were collected and analyzed. There were 10 males and 3 females in the group, with an average age of 41.5 years (range: 13 to 68 years). Nine patients had classic ES and 4 had proximal-type ES. Surgery was the mainstay of treatment. After the operation, four patients received radiotherapy, five received chemotherapy, and one received chemoradiotherapy.</p><p><b>RESULTS</b>Of the 13 cases, only 1 had multi-locus lesion. The average tumor size was (6.07 ± 1.34) cm. The lymph node involvement was found in 46.2% of the patients. Local and distant failure occurred in 50% and 30% patients, respectively. The most common site for dissemination was the lung. Four cases died within 3 years after initial operation. The 1-, 2-, 5-, 10-year overall survival rates of the 11 cases were 72.7%, 54.5%, 27.3% and 9.1%, respectively, with a median survival time of 27 months.</p><p><b>CONCLUSIONS</b>Epithelioid sarcoma is a rare disease. The prognosis for patients with epithelioid sarcoma is poor because of a high propensity for local recurrence, lymph node metastases, and/or distant metastases. The definite diagnosis depends mainly on the pathologic examination. Wide surgical excision is the mainstay treatment, and radiation and chemotherapy have been used occasionally as adjuvant therapy but have had limited success.</p>

ABSTRACT

Background Retinopathy of prematurity is mainly due to retinal neovascularization.Objective This laboratory work was to evaluate the efficacy of different dosage of avastin for inhibiting retinal neovascularization.Methods Ninety 7-day-old clean C57BL/J6 mice were randomized into six groups as follows:air control group,hyperxia control group,hyperxia BSS group and avastin groups.C57BL/J6 mice in air control group were raised in regular air environments.The fifty mice were fed under the environment with 75% ±2% oxygen for 5 days to establish the retinal neovascularization models.The 1.25,2.50 and 5.00 g/L avastin (0.5 μl) were injected inteavtreally in forty-five mice models as low,moderate and high dosage avastin groups respectively,and 0.5 μl BSS was used at the same way in fifteen models as hyperxia BSS group.The mice were sacrificed in the 17-day-old age using excessive anesthesia method and the retina sections were prepared for the calculation of the numbers of vascular endothelial cell nuclei broken retinal inner membrane after hemotoxylin and eosin staining.The expression of CD34 in the retina was detected by immunochemistry.The morphology and distribution of retinal neovascular vessel in various groups were observed using retinal flat.The use of the animals followed the Regulations for the Administration of Affairs Concerning Experimental Animals by State Science and Technology Commission.Results The numbers of cell nuclei broken the inner limiting membrane was significant increased in the hyperxia group compared with the air control group( P<0.01 ),and those in difference doses of avastin were considerably reduced in comparison with hyperxia BSS group (P<0.01) and hyperxia group (P<0.01 ).The decrease of numbers of cell nuclei broken the inner limiting membrane was obvious in low dose of high dose of avastin compared with low dose of avastin (P<0.05 ).CD34 was positively expressed in retina internal membrane of hyperxia group.Retinal flat revealed the regular distribution and normal structure of retinal vessels in air control group and avastin groups.However,retinal and vitreous cavity neovascularization,leakage and enlarged non-perfusion regions in the perimeter of the retina were seen in hyperxia group and hyperxia BSS group. Conclusions Intravitreal injection of avastin can arrest retinal angiogenesis in oxygen-induced retinal neovascularization models in a dose-dependent manner.

ABSTRACT

AIM: To investigate the effect of ginsenoside-Rg3 on the expression of vascular endothelial growth factor (VEGF) and tumor necrosis factor-α (TNF-α) in retina with diabetic rats and its roles in preventing neovascularization in diabetes. METHODS: Sixty male Wistar rats were divided into 3 groups randomly: negative control group, diabetic control group and ginsenoside-Rg3 treatment group (5mg/kg, 0.2mg/mL) followed by establishing diabetic model. The expression of VEGF and TNF-α were measured after 8 weeks. RESULTS: There were significant differences among negative control group, diabetic control group and ginsenoside-Rg3 treatment group in the expression of VEGF and TNF-α (F=129.363, 211.992; all the P<0.01). VEGF and TNF-α expression were significantly higher in diabetic control group and ginsenoside-Rg3 treatment group than that in negative control group (P<0.01), with a significant reduction in ginsenoside-Rg3 treatment group than that in diabetic control group (P<0.01). CONCLUSION: Ginsenoside-Rg3 can down-regulate the expression of VEGF and TNF-α in retina, which may interfere in the development of diabetic retinopathy.

ABSTRACT

We investigated the effects of fish protein hydrolysate (FPH) on growth performance and humoral immune response of the large yellow croaker (Pseudosciaena crocea R.). One thousand and two hundred large yellow croakers [initial average weight: (162.75+/-23.85) g] were divided into four groups and reared in floating sea cages (3 m x 3 m x 3 m). The animals were fed with 4 diets: basal diet only (control) or diets supplemented with 5%, 10% and 15% (w/w) FPH. The results show that dietary FPH levels significantly influenced the growth and immunity of the large yellow croaker. Compared with the control group, total weight gain (TWG) in all treatment groups, relative weight gain (RWG) and specific growth rate (SGR) in fish fed with diets supplemented with 10% and 15% FPH were significantly increased (P<0.05). Similar results were observed in immune parameters [lysozyme activity, serum complements, immunoglobulin M (IgM)]. Lysozyme activity, complement C4 and IgM were also significantly increased (P<0.05) in fish fed with diets supplemented with 10% and 15% FPH, while complement C3 level was significantly increased (P<0.05) in all treatment groups. In general, with the supplementation of FPH, particularly at dose of 10%, the growth performance and immunity of the large yellow croaker can be improved effectively.

ABSTRACT

We examined the effects of conjugated linoleic acid (CLA) on growth, fatty acid composition and enzyme activity of fatty acid oxidation in the liver of large yellow croaker. We divided 1600 fish (average initial weight 150 g) into 4 groups and reared them in 8 cages. Four dietary treatments were formulated to contain 0%, 1%, 2% and 4% (w/w) CLA, respectively. The fish were fed for 10 weeks ad libitum twice daily. We found that the dietary CLA had no effect on growth, biometric parameters and whole body proximate (P>0.05), but showed some significant effects on the fatty acid composition in both muscle and the liver. The activities of lipogenic enzymes were slightly depressed in fish fed with increasing levels of CLA when compared with control (P>0.05). Dietary CLA supplementation had no effects on liver lipid content, but significantly increased the contents of saturated fatty acids (SFA) and polyunsaturated fatty acids (PUFA) (P<0.05) and decreased monounsaturated fatty acid (MUFA) content in both muscle and the liver. Dietary CLA inclusion resulted in significant increases of the biologically active cis-9, trans-11 and trans-10, cis-12 isomers in both tissues (P<0.05). The total accumulation of CLA was higher in the liver (3.83%, w/w) than in muscle (3.77%, w/w) when fed with 4% (w/w) CLA. This study demonstrates that large yellow croakers are capable of absorbing and depositing CLA and long-chain n-3 PUFA in the liver and muscle, showing that this species fed with CLA could be an important human food source for these healthful fatty acids.

ABSTRACT

Objective To evaluate the application of non-bioartificial liver support system (ALSS) combined with liver transplantation(LT) in treating mid-or end-stage chronic severe hepati- tis.Methods ALSS plus liver transplantation were employed in treating 28 patients with mid-or end- stage chronic severe hepatitis.Clinical data from the patients before and after treatment were collect- ed.The survive rate of ALSS plus LT group were compared with that of medication group 99 cases and medication plus ALSS group 30 cases.The data were analyzed with t test and X~2 test.Results After 57 times ALSS treatment,the serum total bilirubin(TBil),prothromin time(PT),bile acid, blood urea nitrogen(BUN),creatnine(Cr) and ammonia of all the 28 patients got improved(P 0.05).The clinical symptoms and signs of the patients were ameliorated at median 3 d(1~153 d). All patients were bridged to liver transplantation successfully after median 20 d(1~153 d).The 3 and 6 months post-operation survival rate of ALSS plus LT group(71.4%,71.4%) were significantly higher than those in medication group(18.2%,11.1%) and medication plus ALSS group(36.7%, 26.6%)(P

ABSTRACT

<p><b>OBJECTIVES</b>To investigate the role of focal adhesion kinase (FAK) in the pathogenesis of cardiac hypertrophy induced by hypertension.</p><p><b>METHODS</b>Using immunofluorescent labeling, confocal microscopy and Western blotting, the expression and subcellular localization of FAK in the cardiac myocytes of left ventricle were determined in 2, 6, 12, and 18 month-old rats with spontaneously hypertensive heart failure (SHHF) along with age-matched control Wistar-Kyoto (WKY) rats.</p><p><b>RESULTS</b>There was no significant difference of FAK expression between 2 month-old SHHF and WKY rats (50.5+/-6.9 vs. 49.8+/-5.0, n=6, P>0.05). In contrast with the control groups, the expression of FAK significantly increased in 6, 12 and 18 month-old SHHF rats (130.6+/-3.0 vs. 47.3+/-1.3, 144.7+/-5.4 vs. 46.4+/-3.1, 141.4+/-9.8 vs. 48.5+/-2.2, each groups n=6, P<0.05) with FAK protein primarily cumulated in the intercalated disks and nuclei.</p><p><b>CONCLUSIONS</b>FAK may play a role in the cell signaling transduction leading to cardiac hypertrophy, presumably through regulations of hypertrophic gene transcription and RNA processing.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To observe the clinical efficacy and adverse reactions of Paroxetine combined with electro-acupuncture (EA) in treating depression.</p><p><b>METHODS</b>Forty-two patients with depression were randomly assigned to the observation group (22 patients) treated with EA combined with Paroxetine, and the control group (20 patients) treated with Paroxetine alone, and the therapeutic course for both groups was 6 weeks. The therapeutic efficacy and adverse reactions were evaluated with scores by Hamilton depression scale (HAMD) and treatment emergent symptoms scale (TESS), respectively.</p><p><b>RESULTS</b>HAMD scores determined at the end of the 1st, 2nd, 4th, and 6th week of the treatment course were significantly lower in the observation group than those in the control group (P<0.05). The significant improvement rate evaluated at the end of the 6-week treatment was remarkably higher in the observation group than that in the control group (72.7% vs 40.0%). No significant difference of TESS scores was found between the two groups.</p><p><b>CONCLUSION</b>EA combined with Paroxetine has better clinical efficacy than that of Paroxetine alone, with milder adverse reaction and quicker initiation of effect.</p>
