[Objective]To evluate the influence of subacromial space caused by the relative position of acromion and humeral head,and to provide theoretical guidance for diagnosis,prevention and treatment of subacromial impingement syndrome.[Method]From October 2006 to March 2007,31 shoulders(13 men and 18 women with average age of 54.3)with subacromial impingement syndrome,from our department,were selected to form the patient group,An age and gender-matched of 40 asymptomatic shoulders(18 men and 22 women with average age of 52.8)formed the control group.The acromion index was measured on the Grashey view.The distance from the glenoid plane to the lateral border of the acromion was divided by the distance from the glenoid plane to the lateral aspect of the humeral head to calculate the acromion index.[Result]The average acromion index(and standard deviation)was(0.72?0.05),in patient group,(0.61?0.04)in the asymptomatic,normal shoulders.The difference between the index in the shoulders with subacromial impingement syndrome and the index in normal shoulder was highly significantly(P

Objective To study the effects of green tea extract on the decrease of serum lipids and body mass index in middle-aged person.Methods A total of 248 middle-aged person with mild hypercholesterolemia were randomly divided into 2 groups and assigned to receive tablets containing green tea extract or placebo for 20 weeks.The serum lipids and body mass index were measured.Results The levels of serum total cholesterol and lower-density lipoprotein,and the body mass index were significantly decreased with the treatment of green tea extract(all P

Objective To investigate the changes in ATPase activity of diaphragm in rats with acute organophosphorus poisoning (AOPP) and to explore the effect of Xuebijing injection on the ATPase activity. Methods 24 clean healthy Spraue-Dawley(SD)rats were divided into control group,model group and Xuebijing treatment group by means of random number table,with 8 rats in each group. AOPP model was established by intra-gastrical administration of 50 mg/kg oxide dimethoate. In Xuebijing treatment group,after oxide dimethoate administration,intraperitoneal injection of Xuebijing(10 mL/kg)was given at the same time,while in control group and model group,equal amount of normal saline(NS)was injected via the same route. The rats were sacrificed at 6 hours after model formation,and their diaphragms were taken sterilely. The activities of Na+-K+-ATPase and Ca2+-ATPsae of diaphragms were detected by enzyme linked immunosorbent assay(ELISA). The histopathological changes in diaphragms of rats were observed with light microscopy. Results 6 hours after intoxication,the diaphragm Na+-K+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:5.22±0.74 vs. 9.98±0.37,P<0.01),while the Na+-K+-ATPase activity in Xuebijing treatment group(6.93±1.14) was markedly higher than that in model group(P<0.05). The diaphragm Ca2+-ATPase activity of rats in model group was markedly lower than that in control group(mmol?h-1?g-1:7.45±0.74 vs. 12.08±0.74,P<0.01),while the Ca2+-ATPase activity in Xuebijing treatment group(9.35±1.67)was obviously higher than that in model group(P<0.05)after intoxication for 6 hours. Light microscope observation indicated that there were swelling and necrosis in diaphragm in model group,while in Xuebijing treatment group no necrosis was found. Conclusion The diaphragm was degenerated and necrotic in AOPP rats,Xuebijing injection can lessen the injury in such rats,and the curative effect may be related to the improvement of the Na+-K+-ATPase and Ca2+-ATPsae activities of diaphragm.

Epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) targeted treatment has been a standard therapy for advanced non-small cell lung cancer (NSCLC), but it is not tolerated well by all patients. In China, some studies have reported that traditional Chinese medicinal herbs (TCMHs) may increase efficacy and reduce toxicity when combined with EGFR-TKI, but outside of China few studies of this kind have been attempted.

Objective: To observe the effects of 8 week inspiratory muscle training on lung function, respiratory muscle strength, exercise performance, body composition and lipid metabolism in obese college students, and to provide a reference for optimizing rehabilitation plan for obese patients. Methods: A total of 58 obese college students were randomly divided into experimental group(n=28) and control group(n=30). The experimental group received inspiratory muscle training with 50% of maximal inspiratory pressure(P Imax), 3 times a week for a total of 8 weeks. Except for the intensity set to 5% P Imax, other parameters in the control group were the same as those in the experimental group. Lung function, respiratory muscle strength, exercise performance, body composition and blood lipids were measured before and after intervention. Results: The completion rates of the training program (adherence) in the experimental group and the control group were 98.0% and 99.2%, respectively. No serious adverse events occurred during intervention. After intervention, P Imax and 6 minute walk test (6MWT) distance increased (t=-7.44, -4.11, P<0.05), ratings of perceived exertion (RPE) and heart rate decreased after 6MWT (t=2.13, 2.63, P<0.05), but there was no significant difference in lung function, body composition and blood lipid level in the experimental group (P>0.05). There was no significant change in the above indexes in the control group (P>0.05). Conclusion Eight week inspiratory muscle training can effectively improve inspiratory muscle strength and exercise performance in obese college students, whereas it had no effects on expiratory muscle strength, lung function, body composition and blood lipid profiles.

Amniotic epithelial cells (AECs) have been expected to be a good cell source for stem cell-based cardiac repair. Activin A signaling is required for cardiac differentiation in human embryonic stem cells (ESCs), and bone morphogenetic protein-4 (BMP-4) is an important regulator that controls stem cell fates. Previous study has established an efficient protocol to generate cardiomyocytes from human ESCs via induction with Activin A and BMP-4. The aim of present study was to test the hypothesis that Activin A and BMP-4 could also induce AECs to differentiate into cardiomyocytes in vitro. Human AECs (hAECs) were isolated from human term placenta by trypsin digestion according to the previous reports. Freshly isolated hAECs were examined to detect the expression of cytokeratin 19 by immunocytochemistry. High-density undifferentiated hAECs at passage 1 were sequential treated with 100 ng/ ml human recombinant Actvin A and 10 ng/ml BMP-4. The expression of cardiac-specific genes was examined before and after in vitro induction of cellular differentiation. Freshly isolated hAEC could express cytokeratin 19, the specific marker of epithelial cells. The data showed that hAECs treated with Activin A and BMP-4 were able to express cardiac-specific genes, including Nkx2.5 and alpha-actinin. Our results demonstrated that Activin A and BMP-4 could induce cardiomyocyte differentiation of hAECs, which might be a novel approach to induce differentiation of AECs into cardiomyocytes-like cells.

OBJECTIVETo evaluate facial morphology characteristics of patients with unilateral complete cleft lip and palate (UCCLP) after cleft palate repair in different periods.

METHODS46 nonsyndromic UCCLP patients were chosen as test group and divided into three kinds (under 4-year-old, 4-7-year-old, over 7-year-old) according to periods of palate repair. 38 age and gender matched non-clefts children were involved as control group. 26 cephalometric measurements were measured to evaluate facial morphology of four groups.

RESULTSCompared with patients who received palate repair before 4-year-old, patients who received repair after 4-year-old had more protrusive ANS point (Ba-N-ANS, Ba-ANS) and less Y-axis angle. Patients who received palate repair after 7-yesr-old had greater A-PMP and ANS-PMP than patients who received palate repair before 4-year-old, patients who received palate repair before 7-year-old had smaller ANS-Me but after had no significant difference when compared with non-clefts.

CONCLUSIONWhenever palate repair is undertaken in the period of maxillary growth and development, patients' maxillary growth would be restrained, the delayed repair sample have better lower face height, maxillary protrusion, maxillary sagittal length and mandible growing direction when compared with the early repair sample, that is to say, the delayed repair sample have preferable head-face morphology.

BACKGROUND:Acute myocardial infarction can cause cardiac remodeling and heart failure,as well as skeletal myopathy,affecting patients'quality of life.Exercise therapy is an important rehabilitation method for patients with heart failure;however,the optimal exercise prescription has not been clarified. OBJECTIVE:To compare the effects of different exercise modes(aerobic exercise,resistance exercise)on skeletal muscle remodeling in rats with acute myocardial infarction induced heart failure and to explore the possible mechanism,so as to provide a basis for optimizing the exercise rehabilitation program. METHODS:Forty-eight Sprague-Dawley rats were randomly divided into sham operation group,myocardial infarction group,aerobic exercise group and resistance exercise group.Coronary artery ligation was used to create model of heart failure.After 3 months,animals in the aerobic exercise group and resistance exercise group underwent 12 weeks of corresponding exercise mode interventions,while those in the sham operation group and myocardial infarction group were kept quietly in mouse cages.After the experiment,maximal running speed and maximal weight-bearing load were measured by graded treadmill exercise test and ladder-climbing test respectively,and heart structure and function were evaluated by echocardiography.The heart was isolated,and hematoxylin-eosin staining and Sirius red staining were performed to detect cardiac remodeling.For the gstrocnemius muscle,ATPase staining was performed to observe changes in muscle fiber type and cell cross-sectional area,dihydroethidium method was used to evaluate reactive oxygen species levels,enzyme-linked immunosorbent method was used to determine malondialdehyde content and antioxidant enzyme activity,western blot was used to determine the expression of ubiquitin-proteasome system proteins,and the number of activated satellite cells(Pax7+/MyoD+)were detected by double immunofluorescence staining. RESULTS AND CONCLUSION:(1)Exercise performance:Compared with the sham operation group,maximal running speed and maximal weight-bearing load in the myocardial infarction group decreased(P<0.05);compared with the myocardial infarction group,the maximal running speed of the aerobic exercise group and the maximal weight-bearing load of the resistance exercise group increased(P<0.05).(2)Cardiac remodeling:Compared with the sham operation group,infarction area,myocardial cell cross-sectional area,and collagen content in the myocardial infarction group increased(P<0.05),while leftventricular ejection fraction and shortening fraction decreased(P<0.05);compared with the myocardial infarction group,there was no statistical difference in the above parameters in both aerobic exercise resistance exercise groups(P>0.05).(3)Skeletal muscle remodeling:Compared with the sham operation group,gastrocnemius muscle mass,gastrocnemius muscle mass index,cell cross-sectional area,superoxide dismutase activity,glutathione peroxidase activity,and the number of activated satellite cells decreased in myocardial infarction group(P<0.05),while reactive oxygen species content,malondialdehyde content,and the protein expression of ubiquitin,MuRF1 and MAFbx increased(P<0.05);compared with the myocardial infarction group,gastrocnemius muscle mass index,superoxide dismutase activity,the number of activated satellite cells increased in both aerobic exercise and resistance exercise groups(P<0.05),while reactive oxygen species content and the protein expression of ubiquitin,MuRF1,and MAFbx decreased(P<0.05);compared with the aerobic exercise group,gastrocnemius muscle mass,gastrocnemius muscle mass index,cell cross-sectional area,reactive oxygen species content,malondialdehyde content,the number of activated satellite cells increased in resistance exercise group(P<0.05),while superoxide dismutase activity,glutathione peroxidase activity down-regulated(P<0.05).To conclude,aerobic exercise and resistance exercise can both improve exercise performance of rats with heart failure,and the mechanism is related to reducing oxidative stress,inhibiting ubiquitin-proteasome system activity and activating satellite cells to improve skeletal muscle remodeling.Aerobic exercise has a better effect on improving skeletal muscle oxidative stress,while resistance exercise has a more significant effect on promoting skeletal muscle regeneration.

Objective To evaluate the clinical characteristics and the clinical outcomes of perianal abscess (PA) in neonates.Methods A retrospective review was performed on the collected data of 185 patients of PA in neonates prospectively admitted to Binzhou Medical University Hospital from January 2008 to December 2015.Patients were divided into 2 groups on the parents' intention:nonsurgical treatment and surgical treatment,the standard surgical treatment for PA was incision and drainage with the use of packing.The standard surgical treatment for PA was surgical incision drainage of lower abscess under local anesthesia by the use of filling tamponade iodoform gauze,while the patients receiving conservative treatment took hip bath perianally with topical 1 ∶ 5 000 potassium permanganate,besmearing erythromycin eye ointment outside locally.Incision-thread-drawing procedure was recommended in fistula-in-ano (FIA) after 6 months.Antibiotics were administered in all patients in the early days.The clinical data of age,gender,accompanying diseases,abscess amount and location,treatment approach,healing time and recurrence rates were analyzed with statistical method.Results All patients were boys,time of visiting hospital was 1-25 day,the average time 7.5 days;60 cases (32.4％)had neonatal diarrhea,45 cases (24.3％)had neonatal jaundice,but no patients had severe fever.A single skin lesion was present in 145 patients (78.4％),2 lesions in 30 patients (16.2％),and 10 patients had 3 lesions (5.4％).The most commonly affected sites were at 9 o'clock clockwise direction with 115 (62.2％)lesions on lithotomy position,followed by 3 o'clock clockwise direction with 65(35.1％) lesions by 1 o'clock clockwise direction with 3 (1.6％) lesions and 6 o'clock clockwise direction with 2 (1.1％) lesions.Bacteria cultures were obtained from 123 patients (90.4％,123/136 cases) of surgical treatment and 35 patients (71.4％,35/49 cases) of nonsurgical treatment obtained the results of bacteria culture.The average healing time was (21 ±2) days (10-60 days) in the surgical treatment group,and (36 ± 3) days (9-90 days) in the nonsurgical treatment group,7 out of 136(5.1％) patients had a recurrence with surgical treatment,incision drainage was performed again with the use of packing,and FIA was not found,10 out of 49 (20.4％) patients had a recurrence with nonsurgical treatment group,and 6 out of 49 (12.2％) were spontaneously resolves within the first year of life,4 out of 49 (8.1％) developed into FIA,incision-thread-drawing procedure was performed after 6 months.The significant difference was observed between and nonsurgical treatment and surgical treatment in healing time (t =-6.707,P =0.000),recurrence (x2 =11.347,P =0.001) and FIA formation rate (x2 =10.054,P=0.002).Conclusions PA is an entity in neonates.Incision and drainage of PA is an effective and safe therapy in the early days.Surgery for PA may result in low recurrence rates,a low rate of evolution toward FIA,and a short healing time,which should be considered as the primary treatment.The key procedure is to keep the drainage unobstructed by the use of filling gauze drainage to prevent crissum abscess recurrence.Postoperative care with antibiotics is effective to shorten hospital stays.

Objective To study the effect of carbon fiber postural fixation plate on radiotherapy dose of cervical cancer.Methods The carbon fiber postural fixation plate model was created in the RayStation plan-ning system,and the difference of attenuation coefficient between the model plate in the planning system and the real plate in the actual measurement was compared to verify the accuracy of the position fixing plate mod-el.A total of 10 patients with cervical cancer were selected,and the plate-free plan was designed on the CT im-age without the fixed plate model,and the dose was calculated.After the plate-free plan was completed,the plan was transplanted to the CT image with the fixed plate model to obtain the plate plan,and the dose was calculated.The dosimetric differences of target volume(PTV)and organ at risk(OAR)between the plate-free plan and the plate plan were compared.Two ArcCHECK verification phantoms were established in the RayStation planning system,which were the ArcCHECK verification phantom with the postural fixation plate model and the ArcCHECK verification phantom without the postural fixation plate model.The 10 cervical cancer plans were transplanted into two verification phantoms for dose calculation.Under the Xinhua accelera-tor,ArcCHECK was placed on the postural fixation plate to perform the validation plan,and the effect of the postural fixation plate model in the planning system on the gamma passing rate of the verification plan was compared.Results For the accuracy of the position fixation plate model was created in the planning system:the deviation(d)of the attenuation coefficient obtained in the planning system and the actual measurement is less than 0.3％.For the cervical cancer plan:compared with the plate without plan,the dose of PTV and OAR in the plate with plan was significantly lower.The average dose of PTV was about 1％lower,and the degree of OAR was different,ranging within 3％.For cervical cancer plan verification:the gamma pass rate of the plate model verification plan was significantly higher than that of the platefree plan model verification plan,and the pass rates of 3 mm/3％and 2 mm/2％were increased by 0.69％and 1.50％,respectively.Conclusion The carbon fiber postural fixation plate has a certain effect on the radiotherapy dose of cervical cancer patients.In order to ensure the accuracy of the target dose,it is recommended to add the postural fixation plate model in the plan design.
