Journal of Practical Stomatology 1995;0(04):-
Objective: To investigate correlation between the expression of Fas antigen in hemangioma and vascular malformation.Methods: Anvidin-biotin complex immunohistochemical method was used to detect the expression of Fas antigen in 31 cases hemangioma and 10 cases of vascular malformaton. Results: The expresson of Fas antigen was positive in hemangioma and negative in vascular malformation. Conclusion: The expression of Fas antigen might be related to the natural involution of hemangioma.

Objective To investigate the effect of sevoflurane on blood pressure in patients with different ages and the optimal concen-tration of sevoflurane. Methods 60 patients underwent selective LC operation with conventional induction and sevoflurane maintenance were divided into three groups:the youth group (34 patients), the middle age group (20 patients) and the older age group (6 patients). The SBP, DBP, MAP, CETsev, number of patients, age of patients before induction and 10 min(T1), 20 min(T2), 30 min (T3), 60 min (T4) after induction were recorded. Results Fluctuate of blood pressure were in the normal range after anesthesia maintenance, and MAP were fluctuated within the range of ± 20% before induction. The age under different CETsev were of no significant difference in each time point (P>0. 05). The age composition ratio in different CETsev were of no significant difference in each time point (P>0. 05). As the time of anesthesia extended, the number of patients under 0% ~1%CETsev decreased from 35 to 11; the number of patients under 1% ~2%CETsev increased from 10 to 20;and the number of patients under 2% ~3%CETsev maintened in 14 approximately. Conclusion The effect of sevoflurane on blood pressure of different ages is approximate. 2% ~3% CETsev is the most optimal concentration during the main-tenance of anesthesia.

Flashing light effect on microalgae could significantly improve the light efficiency and biomass productivity of microalgae. In this paper, the baffles were introduced into the traditional flat plate photobioreactor so as to enhance the flashing light effect of microalgae. Making Chlorella sp. as the model microalgae, the effect of light intensity and inlet velocity on the biomass concentration of Chlorella sp. and light efficiency were evaluated. The results showed that, when the inlet velocity was 0.16 m/s, with the increase of light intensity, the cell dry weight of Chlorella sp. increased and light efficiency decreased. With increasing the inlet velocity, the cell dry weight of Chlorella sp. and light efficiency both increased under the condition of 500 μmol/(m2 x s) light intensity. The cell dry weight of Chlorella sp. cultivated in the novel flat plate photobioreactor was 39.23% higher than that of the traditional one, which showed that the flashing light effect of microalgae could be improved in the flat plate photobioreactor with inclined baffles built-in.

Objective:To observe the effect of electroacupuncture (EA) on the expression of erythropoie-tin-producing hepatocyte receptor B2 (EphB2) in the cortex around the infracted area of middle cerebral artery occlusion (MCAO) rats at different timing, and to reveal the possible mechanism of acupuncture in the treatment of cerebral ischemia.
Methods:A total of 180 male Sprague-Dawley (SD) rats were randomly divided into a sham operation group, a model group, an acupoint group and a non-acupoint group, with 45 rats in each group. Rats in each group were further divided into three subgroups: postoperative 3 d, postoperative 14 d and postoperative 21 d groups, with 15 rats in each subgroup. The MCAO model was made by the modified occlusion method. The neurological function score, 2,3,5-triphenyl tetrazolium chloride (TTC) staining, immunohistochemistry assay, immunofluorescence double labeling method and Western blot were used to detect the corresponding indicators.
Results:The neurological impairment of rats was most obvious at postoperative 3 d, and then gradually improved with time, which was more significant in the acupoint group (P<0.05). The change of infarcted volume was consistent with the neurological function impairment. The number of EphB2 positive cells (EphB2+) around the infarcted area was decreased significantly at postoperative 3 d, and then gradually improved with time, which returned to the same level as that in the sham operation group at postoperative 21 d. The increase was most significant in the acupoint group (P<0.05), and the positive cell number was higher than that in the sham operation group (P<0.01). Western blot and immunohistochemistry results were basically consistent. Immunofluorescence displayed that EphB2+ and postsynaptic density-95 positive (PSD-95+) were co-expressed, after the MCAO operation, in the cortical neuron around the infracted area, and the number of co-expressing cells was increased gradually with time, which was most significant in the acupoint group (P<0.05).
Conclusion:Electroacupuncture at Ganshu (BL 18) and Shenshu (BL 23) can significantly improve the neurological function and cerebral infarcted volume ratio of MCAO rats, which may be related to the activation of EphB2 expression in cortex around the infracted area and the promotion of synaptic remodeling.

Objective To systematically review the therapeutic efficacy of acupuncture plus rehabilitation in treating post-stroke spasm and to summarize the commonly-used acupoints.Method The randomized controlled trials and quasi-randomized trials of acupuncture plus rehabilitation for post-stroke spasm published from January 1 of 2005 to December 31 of 2014 in China were retrieved from CNKI, WanFang database, and VIP database, etc. by using computer. The eligible studies were recruited for review. Result Totally 15 studies were enrolled. The Meta-analysis showed that the most commonly used acupoints in acupuncture treatment for post-stroke spasm were Quchi (LI 11), Jianyu (LI 15), Hegu (LI 4), Tianjing (TE 10), Waiguan (TE 5), Zusanli (ST 36), Sanyinjiao (SP 6), Chize (LU 5), and so on. Compared to the controls, acupuncture plus rehabilitation had significantly better effective rate [OR=3.13, 95%CI (2.00,4.89),P<0.00001], recovery rate [OR=2.42, 95%CI (1.53,3.83),P=0.0002], MAS score [MD=﹣0.48, 95%CI (﹣0.62,﹣0.35),P<0.00001], FMA score [MD=5.58, 95%CI (4.96,6.20),P<0.00001], and NDS score [SMD=﹣0.68,95%CI (﹣0.91,﹣0.44),P<0.00001].Conclusion Acupuncture plus rehabilitation can effectively mitigate the post-stroke spasm and is worth promoting in clinic; more high-quality researches are expected as the quality of the currently recruited trials is not so satisfactory.

Objective To explore the effect of high voltage alternating electric field therapy on fracture healing in rats. Methods An animal model of cortical bone defect was successfully established in the unilateral proximal tibia of 41 rats.They were then randomized into an experimental group (21 rats) and a control group (20 rats).The animals in the experimentsl group were given high voltage alternating electric field therapy for 30 minutes daily,while those in the control group only had sham exposure to the high voltage alternating electric field therapy.Rats in each group were sacrificed at days 7,14,21 and 28 post-operation.After blood collection,the operated tibias of the rats were resected with muscle and other soft tissue removed.Bone mineral density (BMD) of the callus at the fracture point was measured using dual energy X-ray absorptiometry (DEXA).The calluses were then cut down and fixed,decalcificated and sliced for histological observation.At the same time serum osteocalcin ( OC ) and bone alkaline phosphatase (RAP) were also detected by ABC-ELISA. Results The BMD examination showed that callus BMD in the experimental group was significantly higher than in the control group at days 14 and 28.Serum OC and RAP in the experimental group were also higher at days 14 day 21,and OC was still significantly higher in the experimental group at day 28.Histological examination showed that in the early stages of bone healing hematoma absorption and organization appeared earlier in the experimental group than in the control group,with remarkable osteoblast and chondroblast proliferation.While at the later stage,bone trabeculas connection and mineralization also appeared earlier in the experimental group than in the control group. Conclusions High voltage alternating electric field therapy may promote fracture healing by accelerating hematoma absorption and organization,elevating osteoblast proliferation and differentiation as well as promoting extracellular matrix secretion and mineralization.The underlying therapeutic mechanism might be related to the increased expression of OC and RAP caused by exposure to the high voltage alternating electric field.
