To study the antioxidative stress effect of probucol for nonproliferative diabetic retinopathy. METHODS: Sixty - eight clinic patients with nonproliferative diabetic retinopathy were selected from January, 2012 to August, 2013. According to the random number table, the patients were divided into control group and observation group, the control group was received conventional medicine for hypoglycemic therapy, and the observation group was given probucol (0. 375g, twice daily) on the basis of control group. All patients were followed up for average 11. 58 ± 0. 17mo. At the same time 16 healthy volunteers matched with baseline were collected as normal control group. Changes in fasting blood glucose, postprandial blood glucose, glycosylated hemoglobin, the staging progress rate and the remission rate of diabetic retinopathy, and indicators related to oxidative stress, such as, total antioxide capacity ( TAOC ) , superoxide dismutase ( SOD ) , and methane dicarboxy aldehyde ( MDA ) , of two groups of patients before and after therapy were observed.RESULTS: Fasting blood glucose, postprandial blood glucose, and glycosylated hemoglobin of patients in two groups before and after therapy showed no significant changes, and the differences had no statistical significance. The staging remission rate and the progress rate of diabetic retinopathy of the control group after therapy were 3% and 19% respectively. The staging remission rate and the progress rate of diabetic retinopathy of the observation group after probucol therapy were 18% and 5% respectively. ln comparison with the control group, the difference had statistical significance (P<0. 05). TAOC, SOD, MDA of the control group before and after therapy had no obvious change, but TAOC, SOD of the observation group after therapy had significantly increased, and MDA had significantly decreased ( P < 0. 05 ), with statistical significance in comparison with the changes of the patients in the control group after therapy (P<0. 05).CONCLUSlON:Probucol can improve the antioxidative stress status of the patients with nonproliferative diabetic retinopathy, and enhance the therapeutic effect of the patients with diabetic retinopathy.

Objective To evaluate the efficacy and safety of intense pulsed light and diode laser for axillary hair removal. Methods Clinical trials on 61 persons using intense pulsed light and diode laser to depilate axillary hairs were conducted. 36 persons were treated by IPL and 25 persons by diode laser.Treatments were carried out in three times at 8-week intervals, and a final assessment was made 3 months following the third theatment. Results Both IPL and diode laser reduced the hair count substantially! the IPL group effective rates were 80. 6 % and the diode laser group, 76. 0 %. They had no statistical significance was (P>0. 05)). Conclusions Intense pulsed light and diode laser are effiective and safe for hair removal.

This study was aimed to explore the clinical efficiency of modified Xiao-Y ao (XY) powder and acupuncture in the treatment of diarrhea-predominant irritable bowel syndrome (D-IBS). A total of 90 D-IBS patients were randomly divided into the treatment group and control group, with 45 patients in each group. Patients in the treatment group received acupuncture combined with modified XY powder. Patients in the control group received oral administration of montmorillonite powder, compound glutamine enteric-coated capsules, compound azintamide enteric coated tablet. Four weeks were one treatment course. After two treatment courses, the pretreatment and posttreatment symptom score, the score of Hamilton Depression Rating Scale (HAMD)/(HAMA), and the overall efficacy were compared. The results showed that compared with pretreatment, clinical symptoms were improved in varying degrees after treatment in both groups (P < 0.05 or P < 0.01). HAMD and HAMA were significantly decreased (P < 0.05). The treatment group had obvious advantages compared to the control group (P < 0.05). The overall efficacy of the treatment group was 91.11%, which was significantly higher than the control group of 68.89%(P < 0.05). It was concluded that modified XY powder and acupuncture can quickly relieve gastrointestinal symptoms, improve anxiety and depression. It is an effective treatment method for D-IBS.

Objective To evaluate the efficacy of radiosynovectomy with 32P colloid in haemophilic synovitis of adolescents. MethodsRadiosynovectomy with 32P colloid was primary performed on 26 male haemophilic patients(26 joints),whose average age was 16 years(11 to 21 years).The average dose of 32P colloid was 2.1 mCi(1.0 to 3.0 mCi). Results After 6-month interval,haemarthrosis was reduced by no less than 30% in 23 patients,with a total efficacy of 88.5%.The mean frequency of haemarthrosis was reduced from 1.9 per month of presynovectomy to 0.3 per month of postsynovectomy(P

AIM: To investigate the effects of angiotensin-converting enzyme inhibitors (ACEI), fosinopril, captopril and angiotensin II AT 1 antagonists, valsartan on tissue factor (TF) expression on monocytes induced by lipopolysaccharide (LPS). METHODS: Mononuclear leukocytes from normal delivered female umbilical veins were incubated with bacterial LPS in presence or absence of different ACE inhibitors .At the end of incubation, the cells were disrupted by 3 freeze-thaw cycles. TF procoagulant activity was assessed by a one-stage clotting assay. RT-PCR was used to check TF mRNA expression, and GAPDH mRNA was used for parallel assay. RESULTS and CONCLUSION: The results showed that increased expression of TF mRNA induced by LPS was inhibited by fosinopril, captopril and valsartan, respectively, and the procoagualant activity of monocytes was also reduced.

Aim To explore the changes of Apelin/APJ system in LPS-induced injury of rat pulmonary mi-crovascular endothelial cells( PMVECs) , and the effect and mechanism of Apelin. Methods PMVECs were cultured with the explant technique, and the identifica-tion of rat PMVECs was carried out by immunocyto-chemical staining of factorⅧrelated antigen. MTT as-say was used to evaluate the viability of PMVECs. The mRNA expression of Apelin and APJ was detected by RT-PCR. The protein expression of PCNA and the phosphorylation of Akt was analyzed by Western blot. Results The mRNA expression of Apelin and APJ showed a compensatory increase after LPS treatment for a short period of time ( P<0. 01 ) , but with the exten-sion of time, which was significantly inhibited, even lower than the control group ( P<0. 05 or P<0. 01 ) , suggesting that Apelin/ APJ system might be involved in LPS-induced PMVECs injury. MTT results showed that 10 -6 ~10 -9 mol · L-1 Apelin obviously promoted the proliferation of rat PMVECs ( P <0. 05 or P <0. 01 ) , and with certain concentration and time de-pendence. Moreover, Apelin also improved the LPS-induced PMVECs injury in different degrees ( P<0. 05 or P < 0. 01 ) . In addition, Western blot analysis showed that Apelin significantly reversed the decrease of the protein expression of PCNA and the Akt phos-phorylation level induced by LPS ( P <0. 05 or P <0. 01 ) . Conclusions The Apelin/APJ system is in-volved in LPS-induced PMVECs injury. Apelin plays an important role in protecting the pulmonary microvas-cular endothelial function and reversing the LPS-in-duced PMVECs injury, which might be related to the activation of Akt phosphorylation pathway.

A new method was established for the direct, rapid and quantitative analysis of pesticide residues, dimethoate chlorothalonil and malathion by low temperature plasma ( LTP) ionization miniature ion trap mass spectrometer. The LTP ionization probe and sample inlet of ion trap mass spectrometry were enclosed in a metal cavity. With non-contact heating, the samples placed on the sample platform were desorbed into gaseous phase and ionized by LTP ionization probe. The results showed that closed ionization had an edge over the opened ionization. The quantitative analysis of 3 pesticides within the range of 0. 5-10 mg/L was realized by optimizing heating time and flow rate of air, and the relative standard deviations of signal intensity is less than 11%. LODs of pesticide, which were obtained within 5 s, were as low as several hundred pictograms. The results showed that the method could be used for the analysis of pesticide residue on green and organic fruits or vegetables.
