Antiretroviral therapy(ART)has been started in an increasingly earlier period in clinical practice.However,owing to the failure of immunological reconstitution or maintenance of latent HIV-1 reservoir in present antiviral treatment,interleukin-2(IL-2)is widely used as an adjuvant to ART with a view to intensifying immunological reconstitution and to activating latent HIV-1 infections.Some conclusions could be drawn as follows,1)IL-2 can extend the half-life of CD+4 T cells and increase the number of CD+4 T cells.2)Compared with ART alone,IL-2 and HAART combination can not reduce HIV-1 related opportunistic infection or death.IL-2 clinical usage is mainly focused on purging HIV-1 reservoir.3)IL-2 combined with ART could increase out flow rate of HIV-1 latent reservoir to reduce HIV-1 infected quiescent memory cells in peripheral circulation even to an undetectable level.4)IL-2 is supposed to be used periodically and for a long period of time.

Objective To study laparoscopic pelvic lymphyectomy combined with vaginal hystectomy in the treatment of patients with stage Ⅰ endometrial carcinoma.Methods The data of 77 patients with stage Ⅰ endometrial carcinoma were reviewed retrospectively. These patients divided into the laparoscopic group and abdominal group according to the operation style. The operation time, blood loss, postoperation complication, rehabilition of the digestion tract, satisfaction degree to the operation of two groups were compared.Results There was no serious complications in the both groups. In the laparoscopic group, the operation time was longer than the abdominal group ( P<0.01), but so far as to the blood loss, the time of rehabilition of the digestion tract, the number of lymphyectomy, the postoperation pain alleviation and the degree of postoperation depression were superior to the abdominal group ( P<0.01).Conclusion Though the Laparoscopic operation takes longer time than the abdominal operation, it has much more advantage: mimimal blood loss, minimal abdominal scar, rapid postoperation rehabilition, much better pain alleviate, less urine retention.

Objective To investigate changes of brainstem auditory evoked potential (BAEP)and somatosensory evoked potential (SEP) in patients with acute cerebral infarction,and discuss their relation with prognosis of the patients.Methods The study involved 60 patients with acute cerebral infarction.Changes of BAEP and SEP in each patient were detected and recorded continuously.Prognosis evaluation was performed by using GCS.Another 60 age-matched and gender-matched healthy human beings were enrolled as controls.Results Incubation period of BAEP wave Ⅰ had no significant difference between the cerebral infarction and control groups (P ＞ 0.05).However,interspike intervals of other BAEP waves in cerebral infarction group were different from those in control group (P ＜ 0.05).A series of waves of SEP (P14-N60) were all significantly prolonged in cerebral infarction group (P ＜0.05).Conclusion BAEP and SEP can effectively reflect function of brain stem in patients with acute cerebral infarction and have some values in determining their prognosis.

BACKGROUND:The auditory ossicle chain reconstruction is stil an important method to treat conductive deafness. Although a great variety of materials have been applied, the blood supply of otosteon after the implantation is ignored. Moreover, there is no real bone formed.
OBJECTIVE:To observe the angiogenesis of vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold which is implanted into the otocyst of guinea pig.
METHODS:Total y 60 guinea pigs were randomly divided into experimental group (vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold), col agen I control group (col agen I modifiedβ-tricalcium phosphate porous scaffold) and blank control group (β-tricalcium phosphate porous scaffold). The guinea pigs were executed under anesthesia at weeks 1, 2, 3, 4 respectively. The surface of scaffolds was observed by scanning electron microscopy. The angiogenesis of scaffolds were observed by hematoxylin-eosin staining and CD34 immunohistochemistry staining, and then the microvascular density was counted. The osteogenesis of the scaffolds was observed by toluidine blue staining.
RESULTS AND CONCLUSION:Endothelial cel proliferation and lumen formation could be observed after 1 week in the experimental group, and the angiogenesis reach the peak after 3 weeks with traffic branches formedbetween micropores. In the other two groups, the lumen formed at 2 weeks but no traffic branches were visible. The sprouting of new blood vessels in the pores were observed more in the experimental group than the other two groups (P<0.05). The adherence and proliferation of cel s could be examined in the surface and pores of the scaffold by scanning electron microscope. After 4 weeks, the osteogenesis could be observed by toluidine blue staining, especial y in the experimental group. These findings suggest that the vascular endothelial growth factor and col agen I modifiedβ-tricalcium phosphate porous scaffold can realize an effective vascularization in the environment of guinea pigs’ middle ear. What’s more, the scaffold also can promote bone formation.

Obj cetive A large number of recent studies show that sevoflurane anesthesia may cause learning and memory dysfunction.The aim of this study was to explore changes of learning and memory ability and hippocampal volume in infantile rats after neonatal interrupted and repeated inhalation of 2.6% sevoflurane through detecting the learning and memory ability by Morris water maze and the hippocampus volume by MRI.Method s Thirty two neonatal SD rats were randomly devided into two groups (n=16):experimental group and control group.Rats inhalated 2.6%sevoflurane in the experimental group and 1 L/min O2 +1 L/min Air in the control group at the postnatal days of 7, 14 and 21 (P7, P14, P21). The learning and memory ability was determined by the Morris water maze test from P31 to P37;The brains of rats were scanned by mag-netic resonance imaging ( MRI) machine under anesthesia with 1%sodium pentobarbital at P37, and the brain and bilateral hippocampal volumes were measured. Results ①In the place navigation test, the escape latency had no significant difference between the two groups (P>0.05).In the spatial probe test, the dwelling time, movement distance and number of entering times in platform quadrant decreased slightly in experimental group compared with those in the control group, while there was no significant difference (P>0.05).②The brain volume [(1.53 ±0.18) cm3 vs (1.60 ±0.13) cm3] and right hippocampal volume [(16.15 ±1.76)mm3 vs(16.46 ±1.71)mm3] had no significant difference between the two groups (P>0.05).The left hippocampal volume [(16.46 ±1.71)mm3] was decreased in the experimental group compared with the control group [(18.10 ±2.53)mm3](P<0.05). Conclusion The learning and memory ability has no significant changes in in-fantile rats after neonatal interrupted and repeated sevoflurane inhalation and MRI examination of hippocampal volume is not sufficient for the diagnosis of cognitive dysfunction.

ObjectiveTo evaluate the clinical efficacy and safety of astragalus injection on the immune function in patients with senile sepsis.Methods Sixty patients with old age sepsis in Critical Care Medicine Department of Guangdong Provincial Traditional Chinese Medicine Hospital were enrolled and randomly assigned into control and treatment groups according to the table of random numbers, 30 cases in each group. According to 2012 sepsis guidelines for treatment, including antibacterial drug, mechanical ventilation, visceral function support, etc., the therapy was given to the control group; besides the treatment in the control group, intravenous drip of 60 mL astragalus injection(10 mL per ampoule) in 250 mL 0.9% normal saline was additionally given in the treatment group, once a day for 7 days. Before and after treatment, the immunological indexes, acute physiology and chronic health evaluationⅡ(APACHEⅡ) score, sequential organ failure assessment(SOFA) score, duration of mechanical ventilation and time of stay in intensive care unit(ICU), 28-day mortality and adverse drug reactions were compared between the two groups.Results Before treatment, there were no statistically significant differences in CD3+, CD3+CD4+, CD3+CD8+ and T helper cells /T suppressor cells(Th/Ts)levels between the two groups(allP>0.05), while CD3-NK+ of the control group was significantly higher than that in the treatment group〔(10.47±6.22)% vs. (6.26±4.13)%,P<0.05〕. After treatment in treatment group, CD3+, CD3+CD4+ and CD3-NK+ were increased, CD3+CD8+,Th/Ts were decreased compared with those before treatment; in the control group after treatment, CD3+,CD3+CD8+ and CD3-NK+ were decreased and CD3+CD4+ and Th/Ts increased compared with those before treatment. In the comparisons between the treatment group and control group after treatment, the differences in CD3+, CD3+CD4+ and CD3+CD8+ had statistical significance〔CD3+:(30.30±17.17)% vs.(41.91±22.29)%, CD3+CD4+:(31.54±13.24)% vs.(40.08±15.28)%, CD3+CD8+:(14.25±8.10)% vs.(9.52±9.33)%,allP<0.05〕; while the differences in Th/Ts and CD3-NK+ had no statistical significance(bothP>0.05). After treatment in the treatment group, IgG was increased compared with that in the control group〔IgG(g/L): 13.07±5.43 vs. 10.10±3.96,P<
0.05〕. The differences in IgA, IgM, complement(C3,C4) and total serum complement activity(CH50) in the comparisons between the two groups had no statistical significance after treatment(allP>0.05). The differences in APACHEⅡ score(13.83±6.18 vs. 15.90±7.48), SOFA score(7.38±4.66 vs. 6.89±4.19), time of stay in ICU(day: 11.63±5.13 vs. 13.62±8.08), invasive ventilation time(hour: 155.44±119.68 vs. 224.08±174.15) and noninvasive ventilation time(hour: 55.55±42.24 vs. 98.57±43.17) had no statistical significance in comparisons between the treatment group and control group after treatment(allP>0.05). The difference in 28-day mortality had no statistical significance in comparison between the treatment group and control group〔16.7%(5/30) vs. 20.0%(6/30),P>0.05〕. In 60 cases, there were 2 patients with adverse drug reaction, one diarrhea and another little rashes, the rest of the patients did not appear any drug side effect.ConclusionAstragalus injection combined with conventional western medicine therapy possibly has certain effect on adjustment of disturbance of immunologic functions in old patients with sepsis, and its therapeutic safety is well.
