Objective To observe the effects of standardized three stage rehabilitation treatment on the neu- rological deficit scores (NDS) and ADL performance of ischemic stroke patients.Methods A total of 164 ischemic stroke patients were recruited and randomly divided into a rehabilitation group and a control group.The neurological function and ADL performance of the patients were assessed by using NDS and Modified Barthcl Index (MBI) at the admission,at the end of 1st,3rd and 6th months post stroke.Results No significant differences were found be- tween the rehabilitative and the control groups with regard to NDS and MBI at admission.The NDS demonstrated a decreasing tendency,while the MBI score an increasing tendency in both groups.In the control group,significant difference of NDS was found between admission and the end of 1st month as well as between the end of the 1 st and the 3rd months.In rehabilitation group,significant difference was revealed between all the time points with regard to NDS and MBI scores.At the end of the 1st,3rd and 6th months,the MBI scores of the rehabilitation group were signifi- cantly higher than those of the control group,indicating that the ADL performance of those treated with standardized three-stage rehabilitation protocol was improved quicker than those without the protocol.Conclusion Standardized three-stage rehabilitation treatment could improve the neurological function and ADL performance of the ischemic stroke patients.

Objective To evaluate the functional changes in the isometric,concentric and eccentric muscle strength of the knee extensors and flexors in patients with knee osteoarthritis,and to explore the relationship among these contractions.Methods A Biodex System-3 isokinetic test system was used to assess the isometric,concentric and eccentric strength of the knee extensors and flexors of the involved and uninvolved limbs of 54 patients suffering from osteoarthritis.Results The strength of the knee extensors and flexors of the involved limbs was significantly less than that of the uninvolved legs in the different contraction modes(P＜0.05).The difference was especially marked in concentric and eccentric contraction at low angular velocity.The hamstrings/quadriceps ratio and the dy- namic control ratio showed abnormalities in the muscle balance of the hamstrings and quadriceps.Conclusion Iso- kinetic testing should be applied and the hamstrings/quadriceps ratio and the dynamic control ratio should be analyzed in evaluating patients with knee osteoarthritis.

OBJECTIVE: To evaluate decision regret among patients receiving penile girth enhancement with acellular dermal matrix (PGE with ADM) and to investigate the potential indicators for decisional regret so as to facilitate the decision-making process for this special group. METHODS: In the study, 78 patients receiving PGE with ADM from Jun. 2016 to Jan. 2019 at Peking University People's Hospital and cooperative hospitals were eligible. Penile girth was taken by only one surgeon 1 week before surgery. Hospital anxiety and depression scale (HAD), international index of erectile function (IIEF) and a 10 cm long visual analogue scale named visualized penile image (VPI) were applied to measure psychological burden, erectile function and satisfaction with penile image respectively at the same time. All the patients were followed up for 3 months. Decision regret scale (DRS) was adopted for measuring decisional regret. Multivariate analysis of variance was applied to investigate the potential indicators for regret. Data analysis process was conducted with SPSS (version 24.0; SPSS, Chicago, IL, USA). RESULTS: Mean penile girth recorded before intervention was (8.29±0.30) cm and increased to (9.46±0.29) cm post surgery (t=76.28, P < 0.01). As for both subscales of HAD measuring psychological burden, a signi-ficant reduction in the mean score was seen, that is, 2.8±1.3 (t=19.28, P < 0.05) for anxiety and 3.0±1.2 (t=20.67, P < 0.05) for depression, respectively. The average score of VPI increased by 3.7±1.1 (t=30.63, P < 0.05). There was no significant change in the average score of IIEF measuring erectile satisfaction (t=1.60, P=0.11). Twenty-nine (38.2%) patients expressed regret to some degree, and the mean DRS score was 23.4±14.8. The scores of DRS correlated negatively with scores of visualized penis image (r=-0.348, P < 0.01), and positively with scores of anxiety (r=0.760, P < 0.01) and depression subscale (r=0.471, P < 0.01). The scores of DRS was irrelevant to those of IIEF (r=0.02, P=0.867). The patients with high annual income (> 120 000 yuan) and education level above undergraduate were more prone to experience decision regret after intervention (P < 0.01). CONCLUSION PGE with ADM did augment penile girth and lower psychological burden, the regret rate of which was acceptably low among the patients. High income and good education might indicate more post-operative regret. Additional decision-making aids should be offered to patients with high income and education level above high school.

OBJECTIVETo discuss diagnosis and treatment of post traumatic spasmodic flat foot.

METHODSFrom 2002 to 2007, 7 diagnosed patients were recruited and underwent following procedures: under epidural anesthesia or common peroneal nerve block anesthesia, massage was performed on the peroneal muscles for about 5 minutes, then ankle joint was underwent with passive functional exercise. Feeling muscle relaxation, we held the wounded foot in varus and adducted position forcefully, then immobilized it with short leg cast. After 3 weeks of continuous immobilization, the cast was removed and patients were given physical treatment and functional training.

RESULTSSymptoms of these patients such as claudication and pain in foot were improved, the foot deformity was corrected and foot arch restored to normal. After a follow-up of 6 months,no obvious recurrence was observed.

CONCLUSIONThe diagnosis of post traumatic spasmodic flat foot is based on the careful inquiry of traumatic history,physical examination and X-ray results. Manipulative reduction under common peroneal nerve block anesthesia and cast immobilization is a simple and effective method to treat this disease.

Objective To evaluate the running status of the water-improving projects in Gansu Province in order to further improve the supervising mechanism and raise the efficiency of defluoridation in drinking water.Methods The water-improving projects,either being normal,or intermittent,or discarded and the cause of abnormal running in 33 counties in Gansu Province were surveyed with unified standard method.Fluoride content in water was determined by F-ion selective electrode.Results 993 water improving projects covering 3389 fluorosis villages were surveyed,682 projects worked well[68.68%(682/993)]and had supplied water with normal fluoride contents to 2174 villages[64.15%(2174/3389)]and benefited 116.56 hundred thousand populations.And the rest 311[31.32%(311/993)]projects worked abnormally or supplied unqualified fluoride water.The main causes were the exceeded lasting life,insufficiency of water resources,high fluoride content in water and unqualified administration.Conclusions Most of the water-improving projects in Gansu Province are basically running normally,but about 1/3 of the projects do not function well,so the management of the projects must be improved and consummated.

OBJECTIVETo analyse protein alterations in the seminal plasma of non-obstructive azoospermia patients.

METHODSSemen samples were collected from 11 healthy fertile and 6 azoospermia male volunteers respectively and tested by SELDI-TOF-MS with CM10 protein chip to get protein spectra maps, which were automatically treated with the special softwares of Ciphergen Inc.

RESULTSThe mean peak heights of 28 proteins expressed in the seminal plasma of the azoospermia patients were statistically different from those of the healthy fertile males (P < 0.05 ), of which 24 were of lower contents than in the normal controls, 4 with remarkably significant difference, M/Z 7 196.058, 7 630.573, 7 547.610 and 7 709.833 (P < 0.01).

CONCLUSIONThe seminal plasma proteins of the azoospermia patients were significantly different from those of the healthy fertile males, with decreased contents of most of the different proteins, which might be significantly correlated with the development of azoospermia.

OBJECTIVETo analyse the variability of proteins in the seminal plasma of severe oligospermic and healthy fertile men.

METHODSSpermatic fluid samples were collected from 11 healthy fertile men and 6 severe oligospermic male volunteers and tested by SELDI-TOF-MS with the CM10 protein chip to get the protein spectra maps, which were automatically treated with the special softwares of Ciphergen Inc.

RESULTSThe mean peak heights of 2 lower-abundance proteins expressed in the seminal plasma of the severe oligospermic men were statistically different from the healthy fertile males (P<0.05). Fifteen different proteins existed between the nonobstructive azoospermic and the severe oligospermic group, 7 of which, with m/z of 7,196.058, 7,547.610, 5,780.493, 7,059.844, 7,409.589, 5,379.173 and 10,778.810, also between the non-obstructive azoospermic and the healthy fertile males (P<0.05). Except the latter two, the contents of the other 5 proteins were decreased in the non-obstructive azoospermic men (P<0.05).

CONCLUSIONThe finger prints of the seminal plasma proteins of the severe oligospermic group were similar to those of the healthy fertile males, both significantly different from the non-obstructive azoospermic men. It is suggested that pathogenesis mechanisms differ exist between non-obstructive azoospermia and severe oligospermia but are not the simple accumulation of genetic factors.

OBJECTIVETo investigate the relationship between hemostatic changes in liver cirrhosis patients with different degrees of their liver lesions.

METHODSForty-three patients (35 men, 8 women; age: 25 to 71 yr) with liver cirrhosis were divided into three subgroups (A, B, and C) on the basis of Child-Pugh classification. Among the patients, 13 were classified as Child-Pugh class A, 15 were class B, 15 were class C. 16 healthy individuals served as controls. A series of hemostatic tests and parameters including prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (Fib), factors II, V, VII, VIII, IX, X, vWF assay, antithrombin-III (AT-III), protein C (PC), D-dimer, tissue plasminogen activator antigen (t-PA), plasminogen activator inhibitor activity (PAI) were performed on 43 patients and the 16 healthy controls.

RESULTSPT and APTT were progressively prolonged from A to B and then to C. In comparison to the controls there was a significant difference. Fibrinolytic activity and the activities of factors II, V, VII, IX, X were progressively decreased from A to B and then to C. In comparison to the controls there was a significant difference . AT-III and PC activity were progressively decreased from A to B and then to C. In comparison to the controls there was a significant difference. D-dimer and t-PA-antigen were progressively increased from A to B and then to C. In comparison to the controls there was significant difference. PAI activity did not display significant changes in the four groups.

CONCLUSIONWe found that there is a close relationship between the severity of cirrhosis and the hemostatic changes. Because the deterioration of the coagulation function and increasing fibrinolytic activity parallel the severity of liver cirrhosis, adequate treatment for cirrhotic bleeding should not only correct the coagulation defects, but also lower the increased fibrinolytic activity.

Objective To understand distribution of the endemic fluorosis areas and running status of water-improving defuoridation projects in Gausu province. Methods In 2006, Gansu province endemic fluorosis areas, the content of fluoride in drinking water was measured in villages where water was not improved, running status of delluoridation projects was investigated and the content of fluoride in drinking water were determined in villages where water was improved. Dental fluorosis and skeletal fluorosis prevalence were examined in children in identified high-fluorlde villages. The fluorine content in drinking water was determined by F-ion selective electrode, dental fluorosis of children was diagnosed using Dean method, and adults skeletal fluorosis was diagnosed according to "National Standard for Clinical Diagnosis of Endemic Skeletal Fhiorosis" (GB 16396-1996). Results Water samples were examined in 1997 villages of 26 countries, among which water fluoride content was higher than 1.0 mg/L in 598 villages, accounting for 29.94%(598/1997). All 1215 water-improving and defluoridation projects had been investigated, among which 94.90%(1153/1215) of the projects were functioning well, and intermittent and abandoned projects accounted for 2.96%(36/1215) and 2.14%(26/1215). Mean fluoride of treated water of 1084 water-improving and defluoridation projects had water fluoride content ≤ 1.0 mg/L, accounted for 90.79%(1084/1194) ; mean fluoride of water from 1068 water-improving and defluoridation projects had water fuoride content ≤ 1.0 mg/L, accounting for 91.75%(1068/1164). Total 86 390 children of 8 to 12 year-old were examined, the detectable rate of dental fluorosis was 22.47%(19 414/86 390) and 142 211 adults above 16 year-old were examined, the detectable rate of skeletal fluorosis was 4.20%(5967/142 211). Conclusions Some villages yet have water fluoride content exceeding the standard. Some projects are abandoned and running badly, leading to fluoride content exceeding the standard. In a few areas, the prevalence of children dental fluorosis and adult skeletal fluorosis still exists in Gansu province, the task of prevention and control for endemic fluorosis is still arduous. We must raise the effect of prevention and treatment of this disease.
