Objective To study the clinical efficacy of treatment of atrophic scars of facial hemangioma after isotopes radiotherapy with micro-plasma.Methods A total of 52 patients with atrophic scars were selected under micro-plasma treatment for 4 times,one time every six weeks.And their efficacies were evaluated by compared with single standard of that before and after the treatment.Results By means of rate of clinical index,the total effective rate of atrophic scars was 82.7％.The degree of improvement was as follows:cured in 53.8％,marked effective in 28.9％,effective in 17.3％ and no case ineffective.The total effective rate of hyperpigmentation was 90.3％,including cured in 59.6％,marked effective in 30.8％,effective in 9.6％ and no ineffective cases.Conclusions Micro-plasma is an effective therapy for atrophic scars of facial hemangioma after isotopes radiotherapy,which can significantly improve the depression degree of scars,eliminate the hyperpigmentation and improve the color of scars,but it only has adverse reactions of wound pain and postoperative wound erythema.

Objective To summarize the peri operative therapeutic experience from 67 severe traumatic head injuried patients with a score of 3 8 on Glasgow coma scale (GCS). Methods 67 severe head injuried patients with a score of 3 8 on GCS admitted to our department from Feb. 1992 to Oct.1998 were analyzed. Results Forty five (67 2%) out of 67 patients survived and 22 died. Among the surviving patients 34 (50 7%) achieved a good recovery or moderate disability and left other 11 patients severe deficits(16 5%). Conclusions The prognosis of severe head injuried patients could be improved by correct management before hospitalization, early evacuation of intracranial hematoma with large decompressive craniotomies, intracranial pressure monitoring, moderate hypothermia therapy and other effective prevention and treatment of cerebral vasospasm and complications.

Objective To observe the therapeutic efficacy of needling QIN's eight head acupoints in treating insomnia.Method Sixty patients were randomized into QIN's eight head acupoints group (30 cases) and a conventional acupuncture group (30 cases). The modified Spiegel sleep questionnaire was evaluated respectively after 4-week and 8-week treatment.Result After 4-week treatment, there was a significant difference in comparing the modified Spiegel sleep questionnaire between the two groups (P<0.05), and QIN's eight head acupoints group was superior to the conventional acupuncture group; after 8-week treatment, there was no significant difference between the two groups in comparing the modified Spiegel sleep questionnaire (P>0.05).Conclusion QIN's eight head acupoints group had a more significant therapeutic efficacy compared to conventional acupuncture group after 4-week treatment.

Objective To dynamically monitor the blood glucose in traumatic brain injury (TBI) patients within three days after admission, and to assess the impact of hyperglycemia on prognosis. Method Between 2007 and 2008, 62 TBI patients, who were admitted within 6 hours after the ineidence of injury without diahetes or severe combined injuries, were involved in this study. Blood glucose was monitored at 4 time points (instantly, 24 hours, 48 hours, and 72 hours after admission). Patients were classified into the mild, the moderate, or the se-vere TBI group according to GCS (Glasgow Coma Scale) scores, being classified into the survival or the dead group according to prognosis, or into the mile or severe hyperglycemia group depending on whether the blood glucose ex-ceeds 11.1mmol/L on admission. T tests and χ2 tests were applied to analyze the relationship among blood glucose levels, the degrees of injury, and the prognosis of studied patients. Results Patients with mild, moderate, or se-vere TBI showed hyperglycemia with different levels, and the blood glucose levels was consistent with the degree of the injury. The blood glucose of the patients in the dead group were significantly higher at all checked time points than those of the survival group, particularly instantly after admission (8.51±2.01 mmol/L vs. 11.54±2.45 mmol/L, P=0.0001, t=4.988). The mortality of patients with severe hyperglycemia was 64.71%, signifl-candy higher than that of the mild hyperglycemia group 13.95% (P=0.0002, χ2=15.46). The Intensive Care Unit Length of Stay (ICULOS) of the above two groups was 22.6 and 10.2 days,respectively (P=0.021, t= 3.216), but their hospital length of stay (HLOS) showed no statistical difference (P=0.052). Conclusions Hyperglycemia, as an early stress response to TBI, may reflect the degree of the injury. Blood glucose levels that exceed 11.1 mmol/L on admission may imply high mortality of TBI patients, so this could be used as a simple indi-cator to predict prognosis.

Objective To analyze the emergercy epidemiological characteristics of coeualties with head in-jury in Shanghai. Method By a prospective study,the data of 18 076 casualties with head injury during the whole year 2004 collected from 12 joint hospitals in Shanghai were documented well in the unified survey tables with wide-range items failed in by the attending physician, who got the firsthand information from patients and witness.The data were analyzed by using SPPS version 11.5 software. Results Of 18 076 casualties with head injury,the ratio of male to female was 2.11: 1.The mean age of female was older than that of male (t=10.575, P<0.01).The highest incidence of casualties occurred in people of twenties (24.7 % ). The local residents of Shanghai ac-counted for 34.2% of casualties. More casualties often occurred in December,January,Mareh and August than in he rest. Of 5.1% casualties with head injury were assochted with labour work.The leading cause of injury was dif-ferent in patient cohorts of different ages. Fall was the most main cause of trauma in children cohort (aged<14)and the senile patients cohort (aged > 60). The violert assault and traffic accident caused the most head injuries in the adolescent people cohort ( aged 15～34 years old) and the young people cohort ( aged 35～59 year old). The majority of casualties (85.5%) received CT scan.The scalp laceration (40.2% of patients) was seen more often than other types of injury . The mortality of easualties with traumatic brain injury was 0. 5 % . Conclusions The kmowledge of epidemiologieal aend of emergency deparhnent visitors with head injury is amportant guidance to physicians arranging emergency medical resources rationally and formulating a comprehesive prevention stategy of castahies with head injury.

Background To explore the relationship between polymorphism of APOE gene in traumatic brain injury(TBI)patients suffering from traffic accident and the outcome of TBI.Methods TBI patients were randomly selected in this study with caxe-wntrol trial. The genotype of APOE allele was tested by a polymerase chain reaction-restriction fragment length polymorphism ( PCR-RFLP), and the association between different genotypes of APOE alleles and outcome of TBI patients, were analyed.Results In TBI group frequency of APOE ε2 allele was 0. 1010, and frequency of APOE ε2/ε3 was 0. 1596.Both of these results were significantly higher than that in normal people (APOE epsilon 2 was 0. 0050, APOE ε2/ε3 was 0. 0100) (P＜0.05). Frequency of APOE ε2 and APOE ε2/ε3 in TBI group who died was 0. 1970 and 0. 2727. These were significantly high compared to TBI patients who had good recovery.Conclusions APOE allele ε2 and APOE genotype ε2/ε3alleles indicate a poor prognosis of traumatic brain injury patients.

Objective To evaluate the incidence,potential hazards and effective countermeasure for perforator stroke (PS) resulting from stent angioplasty of symptomatic intracranial artery stenosis.Methods Peri-operation PS complications of 258 patients receiving Gateway balloon-Wingspan stenting for severe symptomatic intracranial stenosis were analyzed.The incidence,clinical course,and prognosis of PS resulting from stenting were recorded.Special attention was given to the anatomical features,clinical manifestation and video materials of patients with PS.x2 test was used for statistics.Results Two hundred and fifty-five patients received stent angioplasty successfully and 7 patients had PS ( incidence rate 2.7％ ).The patients with basilar artery stenosis had a higher incidence of PS resulting from intracranial stenting (6.1％,4/66) than patients with middle cerebral artery stenosis (2.5％,3/118) (x2 =2.320,P =0.025 ).The potential hazards for PS included preoperative perforator stroke adjacent to the stenotic segment and prominent dissection during operation.Six patients presented symptoms after awake from general anaesthesia and one had symptoms 3 hours after stenting.One deteriorated gradually and the others reached the maximum deficit almost at once.At the follow-up of 3 months,3 patients were disabled and scored one,two,two by mRS respectively.Conclusion The incidence of PS resulting from intracranial stenting was low and the prognosis was not disastrous.Stenosis at basilar artery and preoperative perforator stroke adjacent to the stenotic segment were potential risk factors for PS complication.Proper maneuver of angioplasty may decrease the incidence of PS and improve the prognosis.

Objective To assess the safety and efficacy of the treatment for symptomatic atherosclerotic high-grade stenosis in middle cerebral artery with Wingspan stent.Methods The medical records of Wingspan stenting for 102 cases with symptomatic middle cerebral artery high-grade stenosis from February 2008 to May 2012 in our hospital were reviewed retrospectively.All of the patients suffered from ischemic stroke or transient ischemic attack ( TIA ) attributed to the atherosclerotic high-grade stenosis in middle cerebral artery and the stenosis of 70%to 99%was confirmed by DSA before the stenting procedure.All the stroke, death, TIA within 30 days after the stenting procedure or during the follow-up beyond 30 days were observed and recorded.In-stent restenosis were recorded after DSA or CTA was performed 6 months later.χ2 test or Fisher exact test was used to compare in-stent restenosis rate among patients with different clinical and pathological conditions.Results Stenting procedure were successfully performed in 100 patients (98.0%,100/102).The mean degree of stenosis was reduced from (81.0 ±8.4)% to (15.3 ±6.7)%right after surgery.Eight adverse cardiovascular events (7.8 %, 8/102) occured within 30 days ,including seven stroke or death ( 6.9%, 7/102 ) and 1 TIA.The mean clinical follow-up duration was ( 29 ± 15) months in 82 patients, and 9 ischemic events were documented (4 cases of ipsilateral recurrent stroke , 3 cases of ipsilateral TIA, and 2 cases of contralateral ischemic stroke ).The mean radiological follow-up duration was (11 ±9) months in 55 patients.Among them, 8 patients (14.3%) had in-stent restenosis and 3 patients had symptomatic restenosis.The restenosis rate in patients with age ≤49 years.(25.0%,7/28) was higher than those with age >49 years ( 3.7%,1/27 ) ( P>0.05 ).The restenosis rate in patients with lesion size>7.5 mm(25.0%,7/28) was higher than those with lesion size ≤7.5 mm (3.7%,1/27)(P>0.05).Conclusions The treatment of symptomatic middle cerebral artery high-grade stenosis with Wingspan system was relatively safe and associated with a low perioperative complication rate.The long-term efficacy of the treatment for symptomatic atherosclerotic high-grade stenosis in middle cerebral artery with Wingspan stent is prominent.

In recent years, immunotherapy, especially immune checkpoint inhibitors, has shown obvious advantages in prolonging the survival of patients with advanced tumors, and the tumor microenvironment is one of the important factors affecting the efficacy of immunity. Patients with microsatellite-stable colorectal cancer exhibit immune responses in combination with immune checkpoint inhibitor therapy. In-depth exploration of the tumor microenvironment characteristics of microsatellite-stable colorectal cancer and the application of combined immune checkpoint inhibitor therapy can provide new ideas and directions for colorectal cancer immunotherapy.

Objective To compare the perioperative complications of prophylactic use of three antiplatelet strategies in unruptured intracranial aneurysms treated by stent assisted coiling. Methods A total of 203 consecutive patients were brought into this retrospective study including the following three groups:the loading group (n=54), with a loading dose of 300 mg to 600 mg clopidogrel at 2 h to 24h before the stenting; tirofiban group (n=50), a loading dosage of tirofiban (8 μg/kg/min over 3 min) followed by a 0.1μg/kg/min maintenance dosage; dual antiplatelet group (n=99), dual oral antiplatelet drugs (clopidogrel 75 mg + aspirin 100 mg) pretreated for 3-5 days before the operation. Events of hemorrhage and thromboembolism were recorded and the complications were compared to assess the safety and efficacy of various antiplatelet strategies. Chi-square or Fisher exact tests were used for categorical variables. Results The hemorrhagic rates were 11.1% in loading group, 2.0% in dual antiplatelet group, and 0% in tirofiban group, respectively, while the thromboembolic rates were 7.4% in loading group, 4.0% in dual antiplatelet group, and 0% in tirofiban group, respectively. For total complications, significant difference (P<0.05) existed among the three groups, and the complication rate in loading group was significantly higher than that of the dual group (P=0.016) and tirofiban group (P=0.001), while there was no significant difference between tirofiban group and dual antiplatelet group(P>0.05). The hemorrhagic rate in loading group was significantly higher than that of the dual group (P=0.023) and tirofiban group (P=0.027), while there was no significant difference between tirofiban group and dual antiplatelet group (P>0.05). In subgroup analysis of the loading group, the postoperative thromboembolic rate was significantly higher in those exposed to low molecular weight heparin than those not (P=0.039) with no increase of hemorrhagic events (P>0.05). Conclusions When compared with the dual antiplatelet strategy, tirofiban strategy may be used as a new prophylactic protocol in unruptured intracranial aneurysms treated by stent assisted coiling. Those treated by low molecular weight heparin postoperatively after receiving dual antiplatelet therapy may increase the hemorrhagic risk, although there was a significant decrease in thromboembolic events postoperatively.
