ObjectiveTo observe the effect of multi-rehabilitation techniques on hemiplegic patients.Methods90 stroke patients with hemiplegia were randomly divided into the treatment group and control group with 45 cases in each group. Patients of the treatment group were treated with multi-rehabilitation techniques, and cases of the control group were treated only with instrument of never-muscle rehabilitation.ResultsAfter treatment, the extremity motor function and ability of daily living activities and muscle function of patients of two groups were improved significantly, but there was a significant difference between the treatment group and control group (P<0.05).ConclusionThe multi-rehabilitation techniques is more effective on stroke patients with hemiplegia.

Objective To study the optimum conditions for extracting total flavonoids from Acanthus illicifolius through the two extraction processes.Methods An orthogonal test of L_9 (3~4)was designed to select optimum operation conditions for extracting total flavonoids from Acanthus illicifolius through Soxhelt and ultrasonic extraction process.According to the output of total flavonoids under the different extraction conditions,which were selected as ethanol contents,extraction temperatures and extraction time for Soxhelt extraction process, and extraction time,ethanol contents and ratio of liquid to material for ultrasonic extraction process.Results The optimum conditions were established as follows:ethanol content 60%, extraction temperature 85℃and extraction time 2.5h in Soxhlet extraction process;Ethanol content 50%,extraction time 50min,ratio of liquid to material 40:1 in ultrasonic extraction process.The extraction temperature was the main factor on the Soxhlet extraction process, and the ethanol content on the ultrasonic extraction process.Conclusion The technology of ultrasonic extraction is better than that of Soxhlet extraction to extract the total flavonoids from Acanthus illicifolius.The max output of total flavonoid from Acanthus illicifolius can reach to 3.82%.

BACKGROUND:Recently, studies on three-dimensional reconstruction and biomechanics became more and more. Three-dimensional models of organs were established by modeling software based on image data using computer. Mechanical analysis was conducted using finite element analysis software. After literature retrieval, we found that the principle of three-dimensional reconstruction of human organs is not clear, and the process description is relatively simple. Some is not accorded with the fact. Above studies cannot guide related research. OBJECTIVE:To explore the principle, process, results and further application of three-dimensional reconstruction models of organs, and to provide evidence for future studies. METHODS:We retrieved China National Knowledge Infrastructure for representative literatures about three-dimensional reconstruction of human organs using the computer, and analyzed the principle, process, results and further application of three-dimensional reconstruction models of organs. RESULTS AND CONCLUSION:In combination with established three-dimensional bone models, we explained the principle, process, and application of three-dimensional reconstruction in detail, and laid the theoretical foundation for subsequent biomechanical research. With continuous development of tissue engineering technology, scholars have begun to study the pathogenesis of bone injury from various angles and different aspects so as to better prevent and treat this disease. The related research is stil in its primary stage, and stil needs further investigations. 

Objective To investigate the prevalence of DUOX2 mutations in Chinese patients with congenital hypothyroidism (CH) and to discuss the inheritance pattern of DUOX2 gene.Methods Blood samples were collected from 91 CH children and their genomic DNA was extracted from peripheral blood leukocytes.All exons and exon-intron boundaries of DUOX2 were analyzed by target next-generation sequencing and family trios was established to study the inheritance pattern of DUOX2 gene.Results Fifty-four out of 91 children with CH carried DUOX2 mutation, with a prevalence of 59.34%.Of the 54 CH children, 36 carried DUOX2 biallelic mutations.In all 12 family trios with probands carrying biallelic DUOX2 mutations, the parents carried heterozygous DUOX2 mutations while still showing normal thyroid function, suggesting that CH caused by DUOX2 mutations is inherited in an autosomal recessive manner.Conclusion DUOX2 gene is one of the most frequently mutated genes in Chinese CH patients and its inheritance pattern is an autosomal recessive one.

OBJECTIVETo study the effect of genistein on the expression of heme oxygenase-1 (HO-1) in rats with pulmonary arterial hypertension (PAH) induced by monocrotaline (MCT).

METHODSSixty male Sprague-Dawley rats were randomly divided into 4 groups (n=15), namely the control group, model group, low-dose (20 µg/kg) genistein group and high-dose (80 µg/kg) genistein group. The hemodynamic parameters were measured and the remodeling of pulmonary small arteries was observed by electron microscope (EM). The expression of HO-1 in the lung tissues were detected by Western blotting.

RESULTSCompared with the model group, genistein treatment significantly reduced the elevated mean pulmonary arterial pressure, improved the right ventricular hypertrophy index, and increased the expression of HO-1 in a dose-dependent manner.

CONCLUSIONGenistein attentuates pulmonary arterial hypertension in MCT-treated rats possibly by up-regulation of HO-1 in the lung tissues.

Objective: To understand the energy and major nutrients intake of high school students in Shanghai, and to provide basis for formulating target nutritional interventions and health education. Methods: The probability-proportional-to-size sampling technique was used to select 19 high schools, from which 9 boys and 9 girls from same class were randomly recruited for each grade. A total of 900 high school students were surveyed on their energy and major nutrients intake. Results: The medians of intake of energy, protein, fat, carbohydrate, calcium, sodium, iron, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber were 2 353 kcal/d, 97.3 g/d, 95.4 g/d, 265.4 g/d, 602.1 mg/d, 4 373 mg/d, 24.3 mg/d, 495.6 μgRE/d, 1.08 mg/d,1.21 mg/d, 83.2 mg/d and 1.01 g/d, respectively. Among of them, the medians of intake of energy, calcium, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber for boys and girls were lower than reference standard(P<0.05). The medians of intake of energy and major nutrients in high school students who lived in countryside were less than those lived in suburban and urban(P<0.05), except carbohydrates and iron. The percentages of energy supplied byprotein, fat and carbohydrate were 16.9%, 37.2%and 46.0%, respectively. Conclusion The energy and calorigenic nutrients intake can meet the demand of daily consumption in high school students in Shanghai, but the intake of dietary fiber, some minerals and vitamins have a various degrees of deficiency. The proportion of energy supplied bycalorigenic nutrients is unbalanced.

Objective To observe the protective effects of carnosic acid on retinal ganglion cells (RGCs) in acute ocular hypertension rats model.Methods Sixty male SPF SD rats (8-12 weeks) were randomly assigned to normal control group,carnosic-acid treated group and model control group with 20 rats for each group.The acute ocular hypertension animal model was induced by the perfusion of normal saline solution into anterior chamber of eyes to elevate the intraocular pressure (IOP) to 110 mmHg for 60 minutes in the rats of the carnosic-acid treated group and model control group,and then the carnosic-acid (dissolving in DMSO) was intraperitoneally injected for consecutive 7 days in the carnosic-acid treated group,and only DMSO was injected in the same way in the model control group.The rates were sacrificed 2 weeks after experiment and retinal sections were prepared for histopathological and apoptotic retinal ganglion cells (RGCs) examination by hemotoxylin & eosin staining and TUNEL staining,and immunofluorescence was employed to examine the survival cell number of RGCs.This study protocol was approved by the Ethic Committee for Experimental Animal of Three Gorges University.Results The retinal morphology and structure were clear in the normal control group.The edema of retinal tissue,loosely arranged RGCs and swollen nucleus were seen in the model control group.In the carnosic-acid treated group,the retinal morphology and structure were regular.The retinal nerve fiber layer (RNFL) thickness was (32.96±1.63),(58.96± 1.57) and (50.11±2.37)μm,and the apoptotic cell number was (6.92±2.96),(29.85±6.40) and (14.69± 2.98)/field,and the survived cell number was (2 363.17± 148.45),(1 308.67 ±106.02) and (1 614.17 ±96.39) / 0.235 mm2 in the normal control group,model control group and carnosic-acid treated group,respectively,with significant differences among the groups (F =339.284,81.583,122.68,all at P＜0.01).Compared with the normal control group,the RNFL thickness was thickened,the number of apoptotic RGCs was much more and the number of survived RGCs was decreased in the model control group,with significant differences (all at P＜0.01).In the carnosic-acid treated group,the RNFL thickness was thinner,the number of apoptotic RGCs was reduced and the number of survived RGCs was increased in comparison with the normal control group,with significant differences (all at P＜0.01).Conclusions Carnosic-acid plays a protective effect on RGCs by inhibiting the cell apoptosis in acute ocular hypertension rats.

Objective:To compare the effectivity and safety of ureteral stenting and percutaneous nephrostomy for patients with upper urinary calculi and sepsis.Methods:From June 2013 to June 2019, 429 patients with upper urinary calculi and urosepsis were accepted in the second hospital of Tianjin Medical University. According to surgical decompression, patients were divided into two groups, ureteral stenting (US, n=304) and percutaneous nephrostomy (PCN, n=125).121 patients were accompanied with septic shock in US group, 56 in PCN group. The effectivity of decompression was analyzed separately in patients with or without shock. For decompression, data included the success rate of decompression, the time of infection related parameters (temperature, blood WBC and CRP) returning to normal and the complications (progress of infection within 30min after decompression, perforation of ureter or pelvis). When urosepsis was cured, ureteroscopic lithotripsy was followed for all patients. The operation time, the stone free rate, the rate of using RIRS and the complications were compared.Results:For patients without septic shock, the success rate of decompression in PCN was higher (68/69)than that of US(165/183)( P =0.025); there was no significant difference in hospital stay for infection control and the time of infection related parameters (temperature, blood WBC and CRP) returning to normal ( P>0.05). The rate of infection progress within 30min in US(25/183) was higher than PCN(3/69)( P=0.036). When ureteroscopic lithotripsy was mentioned, the operation time in US(38.5±6.8 min) was longer than PCN(32.8±4.5 min)( P=0.000), the stone free rate and the rate of using RIRS were lower in PCN( P=0.044, P=0.0002). For patients with septic shock, the success rate of decompression in PCN was higher (55/56)than that of US(106/121)( P=0.022). The rate of infection progress within 30min after decompression was still higher in US ( P=0.048), the time of infection related parameters (temperature, blood WBC and CRP) returning to normal was shorter in PCN ( P=0.000, P=0.003, P=0.000). For lithotripsy, the operation time was longer in US ( P=0.017), the stone free rate and the rate of using RIRS were lower in PCN ( P=0.024, P=0.005). Conclusions:For patients with upper urinary calculi and urosepsis, both ureteral stenting and percutaneous nephrostomy can drainage the pelvis effectively. PCN provides quick recovery, especially when septic shock is involved. For the following ureteroscopic lithotripsy, PCN contributes to less operation time and higher stone free rate, reduces the use of flexible ureteroscope.
