Objective To summarize the clinical results and safety of photodynamic therapy (PDT) through 4 years after single and multi-treatments of patients with subfoveal choroidal neovascularization (CNV) caused by age-related macular degeneration (AMD). Methods Clinical data of 73 AMD cases (95 eyes) diagnosed through fluorescein angiography (FFA), indocyanine green angiography (ICGA) and optic coherence tomography (OCT), treated with PDT were reviewed and analyzed in this hospital from June 2000 to June 2004. The changes of best corrected visual acuity (BCVA), fundus pictures, FFA, ICGA and OCT were compared before and after PDT. Follow-up time varied from 3 months to 4 years (mean, 2 years). Results The mean age of 73 patients was 67.8 years old. The BCVA was from (CF/10 cm) to 1.0. At the final follow up, the BCVA was improved (increase≥2 lines) in 39 eyes (41.1%), stabilized (?1 line) in 51 eyes (53.7%) and decreased 2 lines in 5 eyes (5.3%). Fundus hemorrhage and exudation reduced after PDT. FFA and ICGA showed CNV complete closure in 58 eyes (61.05%), partial closure in 6 eyes (6.32%), CNV incomplete closure in 22 eyes (23.16%) and recurrence in 9 eyes (9.47%). After once PDT of 12 eyes with early-stage AMD, the BCVA improved (from 0.6 to 1.5), CNV completely closed, and the OCT showed disappearance of macular edema and neursensory retinal detachment. No CNV recurred in our four years follow-up observation and the BCVA of the patients remained stable. The mean number of PDT treatment was 1.8 per eye in 95 cases. No serious local or systemic complications were encountered. Conclusions Single or multiple sessions of PDT can acheive long-term safety and efficacy. For early-stage AMD patients with minimally classic CNV, PDT can completely make CNV closed and reduce the risk of visual loss.

Objective To observe clinical effects of Guilong decoction combined conventional western medi-cine in the treatment of rheumatoid arthritis with cold-dampness syndrome.Methods 106 cases of rheumatoid arthri-tis with cold-dampness syndrome were randomly divided into the treatment group and the control group,with 53 cases in each group.The control group was orally given methotrexate and hydroxychloroquine,while the treatment group was given Guilong decoction based on the treatment of the control group.The clinical effects of the two groups were observed after a treatment course of 3 months.Results In the treatment group,35 cases were markedly effective, which was significantly higher than the control group(P <0.05);12 cases were effective,and there was no statistically significant difference with the control group (P >0.05).The total effective rate of the treatment group was 88.68%, which was significantly higher than the control group (χ2 =4.810,P =0.028).There were no significant differences of the adverse reaction ratio between the two groups(P >0.05).Conclusion Guilong decoction combined with con-ventional western medicine can obviously improve the rheumatoid arthritis disease severities,the curative effect is re-markable.It is worth popularizing in clinical application.

Background Diabetic retinopathy (DR) is a progressive vision-threatening complication of diabetes mellitus (DM),but its pathogenic mechanism is still unclear.Researches showed that growth arrest-specific gene product 6 (Gas6) /TAM system participates in pathogenesis and development of DR,and stromal-derived factors (SDF) vary in 2-type DM patients.However,whether Gas6/TAM and SDF-1 are associated with DR is below understood.Objective This study was to determine the relationship between the staging of DR and the levels of serum Gas6,SDF-1α and SDF-1β in DM patients.Methods A prospective cohord study was designed in this study.Ninety 2-type DM patients were included in the 3rd Affiliated Hospital of Southern Medical University Hospital from January to August in 2013.The patients were grouped into the non-diabetic retinopathy (NDR) group,background DR group (BDR) and proliferative DR (PDR) group,with 30 for each group.Thirty normal volunteers were enrolled in the same hospital and same period.The periphery blood 2 ml was collected from all the subjects under the consent inform.The levels of serum Gas6,SDF-1α and SDF-1β were assayed by ELISA,and leukocytes,neutrophils,plasma triglycerides (TG),total cholesterol (CHOL),high density lipoprotein cholesterol (H DL-C) and low density lipoprotein cholesterol (LDL-C) levels were detected and compared among the 4 groups.The correlations of serum Gas6,SDF-1 α and SDF-1 β changes with blood inflammatory cells and blood lipid were analyzed.Results The plasma CHOL concentrations were 4.93(4.14,5.44),5.02(4.35,5.69),4.54(3.85,5.93) and 5.99(5.11,6.89)mmol/L in the normal control group,NDR group,BDR group and PDR group,respectively,and the blood CHOL concentrations were significantly higher in the PDR group than those of the normal control group,NDR group,BDR group (P =0.002,P =0.007,P =0.006).White blood cell counts in the normal control group,BDR group were higher than those of the PDR group (P =0.034,P =0.015),neutrophil counts in the BDR group were higher than those of the PDR group (P =0.024),HDL-C in the NDR group was higher than that in the PDR group (P =0.032).LDL-C in the PDR group was higher than that in the normal control group.Compared with the normal control group,serum Gas6 levels were significantly lower in the NDR group and BDR group (P =0.048,P =0.006),and the serum Gas6 level showed an insignificant increase in the PDR group in comparison with BDR group (P =0.297).Serum SDF-1α levels in the PDR group was significantly higher than that in the BDR group (P =0.033) ;serum SDF-1β levels in the PDR group,BDR group were significantly higher than that in the NDR group (P =0.011,P =0.008) and normal control group (P =0.030,P =0.002).Weaker positive correlation was observed between the serum Gas6 and CHOL,TG,LDL-C levels (r=0.285,r=0.200,r=0.241,all at P＜0.05),between SDF-1α and SDF-1β (r=0.190,P＜0.05) as well as between SDF-1β and white blood cell (r=0.183,P＜0.05).Serum Gas6 served as dependent variable,while white blood cell,neutrophil,CHOL,TG,HDL-C,LDL-C,SDF-1α,SDF-1β served as independent variables,multiple stepwise regression analysis showed Gas6 =170.791 + 5.283CHOL (F =5.021,P =0.027).Conclusions Serum Gas6,SDF-1α and SDF-1β probably participate in the development of DR in 2-type diabetic patients.Gas6,SDF-1 α,SDF-1 β may play roles by affecting blood glucose level,angiogenesis,inflammatory cells and blood lipid metabolism.

Objective:To explore any effect of kinesio taping on the head and neck mobility of children with congenital muscular torticollis.Methods:A total of 52 children with congenital muscular torticollis were randomly divided into a treatment group and a control group, each of 26. All were given 20 minutes of routine rehabilitation training daily, 5 days a week for 4 weeks. The treatment group was additionally taped up with kinesio tape for no more than 48 hours once every 3 days for 4 weeks. Before and after the treatment the angles of head tilt and neck lateral flexion and the gaps in left and right neck rotation were measured for both groups.Results:Significant improvement was observed in both groups but there was significantly more improvement among the treatment group. The treatment had a cure rate (46.15%) and an improvement rate (50.00%) significantly superior to those of the control group and a significantly lower rate of ineffectiveness.Conclusion:Kinesio taping along with routine rehabilitation training can better improve the head and neck mobility of children with congenital muscular torticollis.

Objective To explore the establishment of nursing work model and clinical application in anuria ward. Methods Established the nursing model of anuria ward in rehabilitation department, including the establishment of neurogenic bladder functional rehabilitation nursing specialist group. Define organizational structure, division of labor and responsibilities, conduct continuous personnel training, education and assessment, formulate standardized procedures for rehabilitation and nursing of neurogenic bladder function, implement bladder function assessment, bladder function training, health education, etc. Stage summary and continuous quality improvement. Results The scores of nurses' theoretical examination, skill assessment, nurses'own satisfaction and doctors'satisfaction were 79.6 ±2.1 and 78.5 ±3.5, 91.3 ±2.3, 93.2±1.8, 92.5 ±2.4, respectively. After the implementation of the model, the scores were 89.2 ±1.8, 87.6 ±2.7, 96.3 ±3.6 and 97.4 ±1.6, 98.6 ±1.3, respectively. Before and after the implementation of the model, the differences were statistically significant (t=-8.755--7.685, P<0.05). The number of days of indwelling urinary catheter, residual urinary volume of bladder, and urinary system infection cases before the implementation of the model were (31.63 ±8.47) days and (263.38 ±18.62) ml, (15.03±3.10) cases, (21.27 ±1.64) days, respectively; and (8.78 ±4.32) days, (79.39 ±17.36)ml, (5.36 ± 1.35) cases, (12.45 ± 1.78) days, respectively after the implementation. There was significant difference between the two groups (t =- 23.643--5.874, P < 0.05). Conclusions The establishment of nursing work model without urinary tube ward it can obviously improve the nurses'theory and skill operation level of bladder function rehabilitation nursing, nurses themselves and doctors, patients'satisfaction to nurses, and significantly reduce the number of days of indwelling catheter, urinary bladder residual urine, urinary tract feeling and hospitalization days. The nursing work mode of no urinary tube ward is normative and operable, and it is worth popularizing in clinic.

Objective To explore the diagnostic value of transcranial substantia nigra ultrasound in Parkinson's disease(PD)and the clinical characteristics of patients with different substantia nigra(SN)echoes.Methods Sixty patients with PD admitted to Yichun Hospital of Traditional Chinese Medicine from October 2020 to January 2023 were included in study group,and another 60 normal persons who received health examination in our hospital during the same period were included in control group.Both groups were examined by transcranial substantia nigra ultrasound.The SN high-echo area and ratio of total area of hyperechoic substantia nigra to total area of mesencephalon(S/M)of two groups were compared,and the positive rate of PD diagnosed by transcranial substantia nigra ultrasound was calculated.According to the intensity of SN echo,PD patients were divided into PD-SN-group and PD-SN+ group,and the clinical characteristics of patients with different SN echo were compared.Results The SN high-echo area and S/M of study group were significantly higher than those of control group(P<0.05).Transcranial substantia nigra ultrasound showed PD-SN-in 10 cases and PD-SN+ in 50 cases.The positive rate of PD diagnosed by transcranial substantia nigra ultrasound was 83.33%(50/60).There were statistically significant differences between PD-SN+ group and PD-SN-group in gender,age,H-Y stage,age of onset,score of mini mental status examination and score of Montreal cognitive assessment(P<0.05).Conclusion Transcranial substantia nigra ultrasound can better help clinical screening and detection of PD,and improve the positive detection rate of PD.

Objective To investigate the clinical value of eynovial membrane volume measurement by MRI in patients with hemophilic arthropathy receiving radionuclide synoviectomy. Methods Forty two patients,total 63 diseased joint,who hospitalized in the hemophilia diagnosis and treatment center of Henan Province People's Hospital were enrolled in the study after receiving both enhanced an non enhanded MRI, from May 2011 to January 2015.Sixteen patients(21 joints)were treated with 32P radionuclide synoviectomy (PRS)and followed up.The synovial membrane volume were evaluated by enhanced and non enhanded MRI before and after PRS. All data were analyzed by t test. Results The synovial membrane volume had no statistical difference by using the non enhanced(3 104.38±60.19)mm3and enhanced(2 995.19±59.14)mm3 MRI scans (t=-1.369, P=0.191). The synovial membrane volume post PRS (2 479.45 ± 46.48)mm3much lower than that before PRS (2 983.30 ± 42.87) mm3(t=7.831,P=0.000). The magnetic resonance enhanced range after PRS (0.92 ± 0.06) was significantly lower than that before treatment (1.17 ± 0.07) (t=2.108, P=0.048). Conclusion Synovial membrane volume and magnetic resonance enhanced range are important index to predict clinical efficacy of PRS.

OBJECTIVE To optimize the processing technology of honey bran-fried Atractylodis Rhizoma， and to compare the anti-gastric ulcer effect before and after processing. METHODS Combing with entropy-weight and technique for order preference by similarity to ideal solution model， L（9 34） orthogonal experiment design was adopted to optimize the processing technology of honey bran-fried Atractylodis Rhizoma using the comprehensive score of the contents of atractylone， β-cineole， atractylenolide Ⅲ and atractylodine as evaluation index， using the ratio of excipients to medicine， frying temperature and frying time as factors. The validation tests were conducted. The gastric ulcer model of mice was induced by intragastrical administration of anhydrous ethanol； using Compound aluminum hydroxide tablet as positive control， anti-gastric ulcer effect of Atractylodis Rhizoma was compared with that of honey bran-fried Atractylodis Rhizoma using the contents of serum inflammatory factors [interleukin-2 （IL-2）， IL-6， tumor necrosis factor-α （TNF-α）]， ulcer index and inhibitory rate of gastric ulcer as evaluation indexes. RESULTS The optimal processing technology of honey bran-fried Atractylodis Rhizoma was as follows：ratio of adjuvant and medicinal materials of 3∶10 （g/g）， frying temperature at 140 ℃ and frying time of 4 min. Results of 3 validation tests showed that the contents of 4 components （including atractylone）， in honey bran-fried Atractylodis Rhizoma processed by the optimal technology kept stable （RSDs were 3.47%-5.80%， n＝3）； the comprehensive scores were 95.53%-95.89% （RSD＝0.21%， n＝3）. Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma could increase the serum content of IL-2 in mice， but reduce serum contents of IL-6 and TNF-α to varying degrees； honey bran-fried Atractylodis Rhizoma could significantly decrease its ulcer indexes （P＜0.05 or P＜ 0.01）； the improvement effect of honey bran-fried Atractylodis Rhizoma on the above indicators was generally better than that of the same dosage of Atractylodis Rhizoma （P＜0.05 or P＜ 0.01）. The inhibitory rates of low-dose， medium-dose and high-dose Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma to gastric ulcer in mice were 9.18%， 19.30%， 30.70%， and 50.32%， 61.39%， 53.16%， respectively. CONCLUSIONS The optimal processing technology of honey bran-fried Atractylodis Rhizoma is stable and feasible， and the anti-gastric ulcer effect of Atractylodis Rhizoma has been enhanced after being fried with honey bran.
