ObjectiveTo investigate the effects of Ginkgo-Dipyidamolum on nerve symptom, sign and the nerve conduction velocity of patients with diabetic peripheral neuropathy (DPN).Methods60 patients with DPN were divided randomly into observation group and control group with 30 patients in each group. Routine therapy was conducted in control group. On the basis of routine therapy as control group, Ginkgo-Dipyidamolum was used by intravenous infusions in observation group for 4 weeks. The symptoms and physical sign of patients, and nerve conduction velocity (NCV) were observed.ResultsAfter treatment, clinical symptoms, signs and NCV in observation group improved and were significantly different from that before treatment ( P<0.01), also significantly different from control group ( P<0.01).ConclusionGinkgo-Dipyidamolum can improve the nerve symptoms and signs of patients with DPN, and enhance NCV.

Objective To understand the status of resistance to multiple insecticides and the frequencies of kdr mutations in Culex pipiens pallens from north?central Anhui Province. Methods From July to September,2014,the C. pipiens pallens mosquito larvae were collected in Huaibei,Bengbu and Chuzhou cities of the north?central Anhui Province and reared to adults. The female adult mosquitoes at 3-5 days post emergence were tested for susceptibility to the four insecticides,namely 0.05%deltamethrin,5%malathion,0.1%bendiocarb and 4%DDT,by using the standard WHO resistance tube bioassay. The detec?tion of the point mutations of the kdr gene at codon 1014 was conducted by PCR and DNA sequencing in the deltamethrin?resis?tant and?susceptible mosquitoes. Results High levels of resistance to all the four insecticides were found in all the three tested populations,although mosquito mortality varied among populations and test insecticides. Among the test insecticides,DDT showed lowest mortality with no significant difference(F=1.027,P>0.05)in all test populations,whereas significantly differ?ent mortalities were observed among populations for the remained three insecticides tested(deltamethrin,malathion,and ben?diocarb)(F = 23.823,33.955,128.841;all P < 0.01). Two types of non?synonymous kdr mutation at codon position 1014 (L1014F and L1014S)were observed. A positive correlation between L1014F mutation frequencies and deltamethrin resistance levels were detected in the three mosquito populations(r2=0.718,P<0.01). Conclusions The observed high levels of resis?tance to multiple?insecticides coupled with the occurrence of medium to high kdr frequencies in populations of C. pipiens pallens could profoundly affect the mosquito vector control programme in China. The local health departments need to strengthen vector dynamic monitoring and implement rational resistance management strategies.

Objective To study the clinicopathologic features of brain tumors in patients with medically intractable epilepsy. Methods The clinical, radiologic and pathologic features of brain tumors in thirty-six patients with intractable epilepsy encountered during the period from 2008 to 2014 in the Epilepsy Center of Haidian Hospital were retrospectively reviewed. Results There were 18 males and 18 females in thirty-six patients. The mean age of seizure onset and disease duration were (14.05 ± 1.67) years and (10.04 ± 1.19) years respectively. The histological types of brain tumors included ganglioglioma (12/36, WHO gradeⅠ,1/36, WHO gradeⅡ), dysembryeplastic neuroepithelial tumor (2/36, WHO gradeⅠ), pleomorphic xanthoastrocytoma (1/36, WHO gradeⅡ), angiocentric glioma (1/36, WHO gradeⅠ), astrocytoma (4/36, WHO gradeⅡ), oligoastrocytoma (1/36, WHO gradeⅡ, 2/36, WHO gradeⅠ-Ⅱ), oligodendroglioma (1/36, WHO gradeⅠ-Ⅱ,1/36, WHO grade Ⅱ), cavernous hemangioma (4/36) and Sturge-Weber syndrome (1/36). Most of these tumors were located in temporal lobe (25/36, 69.4%). Patients were followed up for 0.5-7 years after operation. One patient was lost for follow up. Seizure outcome after the epilepsy operation revealed that 28 patients (77.8%) had Engel gradeⅠ, 4 patients (11.1%) had Engel gradeⅡ,2 patients (5.6%) had Engel gradeⅢ,1 patient (2.8%) had Engel gradeⅣ. Conclusion Brain tumors in patients with medically intractable epilepsy are almost low grade tumors of the nervous system. Focal cortical dysplasia is existed in most brain tissues from the epilepsy operation. Low grade tumors of the nervous system have close relation with focal cortical dysplasia in patients with medically intractable epilepsy. It is possible that the classifications of pathology diagnosis has connection with prognosis.

Purpose To investigate the role of S3I-201 on tubular interstitial lesion in lupus nephritis.Methods MRt/MpJ mice were designated as the control group.MRL/lpr nice were randomly divided into LN group,S3I-201 group and DMSO group.The serum and 24 h-urine were collected to detect the serum creatinine,blood urea nitrogen and urine protein.Immunohistochemistry was used to detect the expression of FN.Western blotting analysis was used to determine the expression of E-cadherin,α-SMA,MCP-1,ICAM1,STAT3 and p-STAT3.Results Compared with the expression level in control group,the protein level of α-SMA,MCP-1,ICAM1 and FN were increased in renal tissue of MRL/lpr mice,while the expression of E-cadherin was markedly decreased.And the STAT3 was activated in renal tissue of MRL/lpr mice.The administration of S3I-201 could inhibite the activation of STAT3 and ameliorate the expression of E-cadherin,α-SMA,MCP-1,ICAM-1 and FN.Conclusion S3I-201 can relieve the tubular interstitial leison,which maybe concerned with the phosphorylation of STAT3.

OBJECTIVETo explore the difference in the efficacy and effect mechanism of subcortical ischemic vascular disease (SIVD) complicated with depression between acupuncture and medication.

METHODSSixty patients were randomized-into an acupuncture group and a medication group, 30 cases in each one. In the acupuncture group, acupuncture was applied to Baihui (GV 20), Shuigou (GV 26), Fengfu (GV 16), Fengchi (GB 20) and the others, once a day, 6 times a week. The treatment of 4 weeks made one session and totally 2 sessions were required. In the medication group, nimodipine 30 mg, three times a day and fluoxetine 20 mg, once a day were prescribed for oral administration, for 8 weeks totally. Before treatment, at the end of the 4th week and at the end of the 8th week of treatment, cerebral blood flow velocity (CBFV) and solubility CD40 ligand (sCD40L) were determined respectively. The scores in Montreal cognitive assessment (MoCA) and Hamilton' s depression scale (HAMD) were evaluated in the two groups. The efficacies on cognitive function and depression symptoms were compared in the patients between the two groups. Results Compared with the outcome before treatment, mean blood flow velocity (Vm) of middle cerebral artery (MCA), anterior cerebral artery (ACA) and posterior cerebral artery (PCA) was increased significantly at the end of the 4th week of treatment in the two groups (all P<0.05). At the end of the 8th week, Vm was increased much significantly (all P<0.01). The differences were not significant in comparison between the two groups (all P>0.05). Compared with the expression before treatment, sCD40L was reduced significantly after treatment in the patients of the two groups (all P<0.01), but the differ- ence was not significant between the two groups (all P>0.05). Compared with that before treatment, MoCA score was increased significantly after treatment in the two groups (all P<0.01), HAMD score was reduced sig- nificantly (all P<0.01), the differences were not significant in comparison between the two groups (all P>0.05). The total effective rate of cognitive improvement was 86.7% (26/30) in the acupuncture group and was 80.0% (24/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05). The total effective rate of the improvement in depression was 93.3% (21/30) in the acupuncture group and was 86.7% (26/30) in the medication group, the differences were not significant in comparison of the two groups (P>0.05).

CONCLUSIONAcupuncture could significantly increases CBFV and reduces serum sCD40L expressions in the patients of SIVD complicated with depression, and significantly improves cognitive function and relieves depression symptoms. The efficacy of it is similar to that of western medication. The increase of serum sCD40L expression is possibly involved in the occurrence and development of SIVD. Reducing sCD40L expression contributes to the alleviation of damage induced by cerebral ischemia and reperfusion.

Background With the widely application of phacoemulsication for cataract,dry eye-associated symptoms,such as foreign body sensation and burning frequently occur after cataract surgery in some patients.Objective This study was to evaluate the repair effects of recombinant human epithelial growth factor (rhEGF) on ocular surface injuriy after phacomulsification. Methods This was a prospective study,and informed consent was obtained from each subject before the experiment.One hundreds and twenty eyes of 89 consecutive patients after phacomulsification for age-related cataract were collected and randomized into rhEGF group,hyaluronic acid group and control group and 40 eyes for each.RhEGF drops and hyaluronic acid drops were topically administered 4 times per day for consecutive 4 weeks after surgery in corresponding group,and no drops mentioned above was used in the control group.The 0.3％ ofloxacin eye ointment and tobramycin+dexamethasone drops were used as the element drops in all patients of each group.Corneal fluorescein staining score,tear film break-up time ( BUT),Schrimer Ⅰ test without topical anesthesia were performed 1 day before surgery and 1 day,1 week,2 weeks and 1 month after surgery.Results The demography and the relevant surface examinational outcomes were no significantly different among the rhEGF group,hyaluronic acid group and control group in preoperation (age:F =3.74; gender:x2 =0.615; corneal fluorescein staining:F =0.247 ; BUT:F =0.579 ; Schrimer Ⅰ test:F =0.475 ; all P＞ 0.05 ).With the prolong of the time,the corneal fluorescein staining scores and Schrimer Ⅰ test values appeared a early ascent and latterly decline,and the BUT value showed a early shorten and latterly restore,with a statistically significant differences among various time points( F时间 =6.754,6.079,6.233,P＜0.01 ).Meanwhile,statistically significant differences were found in the corneal fluorescein staining scores,Schrimer Ⅰ test values and BUT among these 3 groups (F分组 =4.953,4.511,4.071,P＜0.05 ).The corneal fluorescein staining scores in the rhEGF group were significantly lower than those in the hyaluronic acid group at 2 weeks and 1 month after operation(P=0.039,0.014),and the BUT values in the rhEGF group were significantly longer than ones in the hyaluronic acid group at 1 week and 2 weeks after operation (P =0.019,0.007).The Schrimer I test values were significantly reduced in the rhEGF group compared with hyaluronic acid group at 1 week,2 weeks and 1 month after operation (P=0.022,0.003,0.019). Conclusions RhEGF promotes the repair of the ocular surface injury in the patients with age-related cataract after phacomulsification.
