Objective To study the effects and techniques of microsurgical resection of giant hypervascular meningiomas. Methods A retrospective analysis was performed on clinical data of 32 cases of giant hypervascular meningiomas in this hospital from June 1999 to June 2002. Results The Simpson Grade 1 resection was achieved in 15 cases, Grade 2 in 9 cases, Grade 3 in 6 cases, and Grade 4, 2 cases. There were 2 fatal cases. Complications included 4 cases of intracranial hematoma, 6 cases of cerebral edema and infarction (re-operation of decompression was required in 4 cases), 1 case of mutism, 3 cases of cerebrospinal fluid leakage, and 1 case of intracranial infection. The mental dysfunctions or symptoms became worse than before the operation in 7 cases. Follow-up checkups in 30 patients found no recurrence in Simpson Grade 1 resection, 4 cases of recurrence in Simpson Grade 2 resection, and 5 cases of recurrence in Grade 3 and 4. A re-operation was performed to remove the tumor in 6 cases. The size of tumor was unchanged during follow-up period in 7 cases undergoing radiotherapy. Postoperatively, assessments with activity of daily living (ADL) associated with mental dysfunctions revealed grade Ⅰ in 25 cases, grade Ⅱ in 5 cases, and grade Ⅲ in 2. No significant differences were seen in ADL assessments before and after operation (P=0.696). Conclusions Every effort should be made to complete the total resection of intracranial meningiomas. Sufficient preoperative preparation, adequate surgical exposure, efficient management of operative bleeding, and fractionated resection of tumor using microsurgical techniques are important factors to improve clinical outcomes.

?AIM: To evaluate the clinical effects, corneal surface shape and corneal thickness variation after treated by Danzhi Xiaoyao Capsule combined with hypromellose 2910, dextran 70 and glycerol eye drops for dry eye in menopausal patients.?METHODS: Eighty menopausal patients ( 160 eyes ) diagnosed as dry eye were randomly divided into groups A and B ( 40 patients each ) . Group A was treated with hypromellose 2910,dextran 70 and glycerol eye drops only and group B was treated with Danzhi Xiaoyao Capsule and eye drops. Before and 1mo after treatment, the clinical effects were evaluated by symptom scores, fluorescein staining ( FL ) , tear film breakup time ( BUT ) and Schirmer Ⅰ test. While the corneal surface regularity index (SRI), surface asymmetry index (SAI) and central corneal thickness ( CCT) were observed.? RESULTS: At 1mo after treatment, the symptoms scores and FL scores of the 2 groups decreased significantly( P<0. 05 ); BUT and SⅠt were significantly increased (P<0. 05). SRI and SAI gradually increased with dry eye exacerbations, after treatment the two parameters significantly reduced than those before treatment. SRI of group B improved significantly more than group A. CCT gradually got thinning with the dry eye condition worsened, which also significantly increased after treatment (P<0. 05);but there was no difference between 2 groups before and after treatment(P>0. 05).?CONCLUSION: Combination therapy of Danzhi Xiaoyao Capsule and hypromellose 2910, dextran 70 and glycerol eye drops for menopausal patients with dry eye is more effective than single eye drops, and can improve the symptoms and signs.

Objective The analysis of hospitalization expenses contributes to effective measures for reducing medical costs.The authors investigated the hospitalization expenses and the influencing factors in orbital cavernous hemangioma (OCH) patients in Shanghai Changzheng Hospital.Methods In view of clinical diagnosis and treatment and social economics,we conducted a single factor analysis and a stepwise multiple linear regression analysis on the influencing factors of the hospitalization expenses of 81 OCH patients from 2002 to 2007.Results The six-year hospitalization expenses of the OCH patients averaged RMB $7 071.4 and the median was RMB $7 038.7,with the costs of surgical materials (54.3%),Western medicine (13.3%) and laboratory examinations (8.1%) as the top three figures.The single factor analysis and stepwise multiple linear regression analysis showed 8 factors to be statistically significant in influencing the hospitalization expenses of the OCH patients,namely,marital status,occupation,complications,anterior orbitotomy,previous treatment,proptosis,hospitalization year and preoperative hospital stay (P

Objective To explore the application of transitional care based on the Omaha system in postoperative rehabilitation of patients with breast cancer.Methods Seventy-two patients after radical mastectomy were assigned into two groups according to admission time,patients from June to December 2011 were set as the control group,patients from February to December 2012 were assigned to the intervention group,each group contained 36 patients.The patients in the control group received routine nursing,while patients in the intervention group were implemented transitional care program with Omaha system as framework from before discharge to 6-week follow-up after discharge from hospital.Nursing effect was compared between two groups from three aspects such as cognition,behavior and status.Results Twenty-three problems were found in the 6-week follow-up for the intervention group,including environmental domain,psychosocial domain,physiological domain and health-related behavior domain.Knowledge,behavior and status scores of the intervention group 6 weeks after discharge were significantly higher than those of the control group [(3.92 ± 0.48) scores vs.(2.41 ± 0.17) scores,(4.11 ± 0.49) scores vs.(2.83 ± 0.25) scores,(3.09 ±0.52) scores vs.(2.32 ±0.39) scores,t=14.81,15.36,9.42,P＜0.01 or 0.05].Conclusions Transitional care based on the Omaha system shows common problems in rehabilitation of patients with breast cancer after operation,and provides standardized program for rehabilitation nursing.It can achieve better nursing effect.

Objective To apply the health education intervention based on protection motivation theory in community female patients with stress urinary incontinence,in order to establish a health behavior and to control urinary incontinence.Methods 96 female patients with stress urinary incontinence were randomly divided into the control group and the experimental group by random number table method,the control group received routine health education,the experimental group received health education based on protection motivation theory.The ICI-Q-SF score,pelvic muscle exercise compliance scale score,urinary incontinence coping efficacy score were compared between the control group and the experimental group.Results The ICI-Q-SF score of the experimental group after the intervention was 5.43 ± 1.77,which was significant lower than that in the control group,7.96±2.98,t=4.88,P＜0.01.The urinary incontinence coping efficacy scores of experiment groups after the intervention was 17.63±1.85,which was higher than that in the control group,13.49±2.46,t=-9.09,P＜0.01.There were 29 cases accounted for 63.04％ with good compliance and 17 cases accounted for 36.96％ with poor compliance in experimental group after intervention,14 cases accounted for 31.11％ with good compliance and 31 cases accounted for 68.89％ with poor compliance in control group after intervention,the difference was statistically significant,x2=9.306,P＜0.05.Conclusions Health education based on protection motivation theory can promote the coping efficacy and health behavior of community female patients with stress urinary incontinence and can effectively control urinary incontinence symptom.

Abstract: Objective To investigate the dynamic changes and clinical significance of specific antibodies in patients with coronavirus disease 2019 (COVID-19). Methods A retrospective study was conducted to collect 141 adult COVID-19 survivors who were followed up in the Eighth Hospital affiliated to Guangzhou Medical University from February 6, 2020, to March 24, 2021. The patients were divided into severe group (severe and critical) and non-severe group (light and ordinary) according to the diagnosis at discharge. The antibody changes of the two groups were compared and analyzed at 1 week, 2 weeks, 1 month, 3 months, 6 months and 1 year after discharge. Results After discharge from hospital, the positive rate of IgG in the severe group was 95.00% after 1 week and 100.00% in the following year, in the positive rate of IgG in the non-severe group was 59.50% after 1 week, 90.08% in 6 months and 76.03% in one year. The level of serum IgG in the severe group was significantly higher than that in non-severe group (Z=-2.441, P=0.015). One-year follow-up: the serum IgG in the severe group was significantly higher than that in the non-severe group (Z=-3.410, P=0.001). The serum IgM level of the severe group after one year follow-up was lower than that of the six months follow-up, the difference was statistically significant (Z=-2.259, P=0.024). The serum IgG and IgM level of the non-severe group after one year follow-up was lower than that of the six months follow-up, the difference was statistically significant (Z=-7.37, P<0.01; Z=3.850, P<0.01). Conclusion The level of serum protective antibody in COVID-19 patients remained high within 6 months after discharge, and remained stable within 1 year after discharge. The antibody titers in the severe group were significantly higher than those in the non-severe group and lasted for at least one year. COVID-19 survivors receive 1 year of natural immune protection, and patients with critical conditions receive immunity for longer periods of time.

Arginine Deiminase(ADI) was purified to homogeneity using ammonium sulfate precipitation,Q-Sepharose Fast Flow anion exchange chromatography and SephadexG-75 gel filtration chromatography. This purification protocol resulted in a 34.5-fold purification of ADI with 31.4% final yield. A molecular weight of about 190 kD determined by native gradient polyacrylamide gel electrophoresis. The enzyme has only one kind of 46 kD subunit determined by SDS-PAGE. Combining the results from the two kinds of electrophoresis,the authors deduce that the enzyme may be a tetramer. The optimum pH and temperature for lipolytic activity of ADI was pH 6.5 and 50℃,respectively. It was extremely stable at 45℃ and retained 97.9% of its original activity for 30 min. The stability declined rapidly as soon as the temperature rose over 50℃. ADI was highly stable in the pH range from pH 5-8. ADI acted on L-arginine but not on D-arginine. ADI catabolism was dependent on metal ions. At their adequate concentration,Mn2+,Mg2+ and Co2+ were the effective promoter,while superfluous Zn2+and Co2+ inhibited ADI activity. L-citrulline did not act on ADI,but L-ornithine inhibited ADI activity. The degradation of L-arginine with ADI catalysis was according to simple Michaelis-Menten equation. The Michaelis constant was 3.2686 mmol/L and the maxi-mum velocity was 2.44 ?mol/min.
