Objective To investigate the polymorphism of the vitamin D receptor gene (VDR)TaqⅠin relation to diabetic retinopathy. Method Fragment length discrepant allele specific PCR(FLDAS-PCR) were used to determine VDR genetypes in 158 patients with diabetic retinopathy and in 198 normal subjects. Results The frequency distribution of VDR genotypes in diabetic retinopathy patients was 106 (67.1%) in TT, 33(20.9%) in Tt, 19(12.0%) in tt; and in normal persons was 165 (83.3%) in TT, 23(11.6%) in Tt, 10 (5.1%) in tt. There was a significant difference between diabetic retinopathy patients and normal persons in distribution of VDR gene TaqⅠgenotypes(P

By the needle-warming moxibustion, 43 cases of diabetic vesical pathological changes,together with 43 cases in the control group, were treated for 30 days, to observe the times of urination,volume of urine and residual urine inside the bladder before and after treatment every day. It has been indicated in observation that needle-warming acupuncture therapy can decrease the time of urination every day, elevate the urine volume each time and decrease the residual urine in the bladder, with a significant difference (P>0.05) in comparison with before the treatment.

Objective To discuss the surgical characteristics,safety and perioperative management of carotid stent angioplasty (CSA) for the treatment of severe carotid artery stenosis (>85%).Methods From December 2011 to May 2016,a total of 25 patients with carotid artery stenosis (>85%) were treated with CSA.According to the stenotic characteristics of the lesion,distal cerebral protection device was employed in performing CSA.During the operation,attention was paid to individualized and detailed surgical management and perioperative management program;the revascularization and the dropping-off of thrombus in cerebral protection device were under close observation,while effort was made to control the occurrence of complications.The patients were followed up for one year to observe the occurrence of ischemic cerebrovascular events.Results The cerebral protection device was successfully deployed after it passed over the severe carotid artery stenosis.After balloon pre-dilation the stent was deployed,and the stent showed satisfactory shape.North America Symptomatic Carotid Endarterectomy Testing (NASCET) showed that the average degree of carotid artery stenosis was decreased from preoperative (91.0±3.1)% to postoperative (21.0±5.1)%.The protective umbrella was successfully retrieved in all patients,and deciduous tissue fragments were observed in 6 retrieved protective umbrellas.During the perioperative period no severe complications,such as cerebral hemorrhage,cerebral infarction,hyper-perfusion syndrome or death,were observed.All the 25 patients were followed up for one year,and no transient ischemic attack,stroke or death occurred.Conclusion In treating severe carotid artery stenosis with CSA,in order to ensure a successful surgery and patient's safety the following points are very important:in-operative individualized and detailed management,perioperative preventive measures,and use of appropriate cerebral protection device.

A case of a 47-year-old female patient who had a severe headache for 2 days was reported. Spontaneous subarachnoid hemorrhage (SAH, hunt-Hess classification Ⅱ level)-anterior communicating aneurysm rupture was diagnosed by brain CT and digital subtraction angiography (DSA) examination.Intravascular interventional aneurysm embolization was performed, and the patient appeared progressive limb weakness 5 days after operation. Physical examination revealed grade Ⅱ upper limb muscle strength and grade Ⅰ lower limb muscle strength. The muscle tone of the extremities was decreased,and the tendon reflex disappeared. The pinprick pain was decreased below the double wrist joints and the ankle joints. After neuroelectrophysiology test and cerebrospinal fluid assay, the patient was diagnosed as Guillain-Barré syndrome associated with subarachnoid hemorrhagic aneurysm embolization.

Objective To observe the effects of indole-3-carbinol on neointimal hyperplasia and restenosis of rat artery after balloon injury and the possible mechanisms.Methods Balloon dilation was used to establish the neointimal injury model of left carotid artery in rats.Twenty Sprague-Dawley rats were randomly divided into single balloon dilation group(control group)and balloon dilation followed by indole-3-carbinol therapy group(therapeutic group).After balloon dilation,indole-3-carbinol(12.5,25,50 mg/d)was applied to the rats for 7 days respectively.The rats were killed two weeks after balloon dilation and the injured vascular specimens were harvested for pathologic examination and immunohistochemical staining.Results ①The neointimal thickness,neointimal area in the therapeutic groups were significantly less than that of the control group(P

Objective To evalute perioperative whole course cerebral protection for patients undergoing carotid endarterectomy (CEA) Methods From 2002 to 2004, 20 patients received CEA in our hospital using whole course perioperative cerebral protection Preoperatively carotid angiography was performed in only one patient, while Doppler ultrasonography and CTA were applied to all patients Measures of intraoperative cerebral protection included general anaesthesia, selective shunting, and transcranial Doppler monitoring (TCD), followed by postoperative delayed removal of tracheal cannula, brain ice bag, maintaining blood pressure and appropriate use of diuretics under the guidance of TCD Results Shunt was used in 7 cases (35%), 15 patients (85%) underwent patch angioplasty There were no postoperative cranial nerves related complications Mortality was 0% Conclusion Perioperative whole course cerebral protection could effectively decrease postoperative cranial nerves related complications in patients undergoing carotid endarterectomy

Objective To investigate the expressions of Th17, CD4 +CD25 +Treg, HLA-DR mRNA in peripheral blood of children with EV71-induced hand, foot and mouth diseases ( HFMD ) and their clinical significance.Methods Stratified random sampling was used to select 60 children with HFMDs from Liaocheng People’s Hospital from February to October, 2014, including 20 mild, 20 severe and 20 critically ill cases.Twenty healthy children were also enrolled as the control group.All the children with HFMDs were given ribavirin (10 mg/kg) for the treatment.The percentages of Th17 and CD4 +CD25 +Treg cells in CD4 +T cells of peripheral blood were determined by flow cytometry, and the expression of HLA-DR mRNA in peripheral blood mononuclear cells was detected by reverse transcription polymerase chain reaction ( RT-PCR).Analysis of variance and SNK-q test were used to compare the expressions of Th17, CD4 +CD25 +Treg and HLA-DR mRNA among groups, and Pearson correlation analysis was performed to reveal the correlations between HLA-DR mRNA and Th17, CD4 +CD25 +Treg.Results Compared with the control group, the expression of Th17 was increased, while CD4 +CD25+Treg and HLA-DR mRNA expressions were decreased in children with HFMDs on d1 of treatment (F=310.4, 81.5 and 545.4, P<0.01).After treatment, Th17 levels in mild group, severe group and surviving children of critically ill group were decreased, CD4 +CD25 +Treg and HLA-DR mRNA expressions were increased, while in fatal cases, Th17 level was still on the rise, and CD4 +CD25+Treg and HLA-DR mRNA expressions were still decreasing. After 10 d of treatment, the difference in Th17 and CD4 +CD25 +Treg levels among mild group, severe group, surviving children of critically ill group and control group was of no statistical significance ( P >0.05), but Th17 level in fatal was still higher and CD4 +CD25 +Treg level was still lower than those in control group (t=16.4 and 12.0, P<0.05).After 10 d of treatment, HLA-DR mRNA expressions in mild group and severe group were increased to the normal level.HLA-DR mRNA expression in surviving patients of critical ill group was still lower than that in mild group and severe group (P<0.05), but was higher than that in fatal patients (t=7.8, P<0.05).Pearson correlation analysis showed that, HLA-DR mRNA was negatively correlated with Th17 level (r=-0.770, P<0.01), and positively correlated with CD4 +CD25 +Treg level (r=0.883, P<0.01).Conclusion The expressions of Th17, CD4 +CD25 +Treg cells, and HLA-DR mRNA are correlated with the severity of HFMD, and may be used for evaluation of disease severity and prediction of disease outcomes.
