Objective To determine the prevalence of dental anxiety in children patients before tooth extraction.Methods A modified Children's Fear Survey Schedule-Dental Subscale (CFSS-DS) and Venham's clinical ratings of anxiety and cooperative behavior were used in 150 children patients ranging in age from 5 to 12 years olds before tooth extraction. The former scale was answered by parents on behalf of their children, and the latter ratings was assessed by the author. Results CFSS-DS scores and clinical ratings of behavior of the children were significantly higher in the children whose oral hygiene condition, dental experience, tooth extraction experience, spirit status on that day and whose mother's educational background were bad or low. A step regression analysis showed that oral hygiene condition had most significant interrelationship with both of the two scales(P<0.01). The correlation of the two scales was high (r=0.67).Conclusion Children’s oral hygiene condition, dental experience, tooth extraction experience, spirit status on that day and their mother’s educational background are closely related to the dental anxiety level. Oral hygiene condition is the most important predictor of anxiety level before extraction and clinical ratings of behavior during extraction.

OBJECTIVETo investigate the expressions of sphingosine-1-phosphate receptors 1-3 (S1P1- 3) in the corpus cavernosum of castrated male rats and its relationship with the NOS/NO/cGMP and RhoA/Rho kinase signaling pathways.
METHODSWe equally randomized 18 eight-week-old healthy male SD rats into a sham-operation control, a castration, and a testosterone replacement (TR) group and harvested the bilateral testes and epididymides from the rats in the latter two groups, followed by 4 weeks of subcutaneous injection of testosterone propionate at 3 mg per kilogram of the body weight per day for those in the TR group and that of plant oil for those in the control and castration groups. At the age of 12 weeks, we measured the serum testosterone (T) level and maximum intracavernous pressure/mean arterial pressure (ICPmax/MAP) of the animals and determined the expressions of SlP1-3, eNOS, P-eNOS, ROCK1, and ROCK2 in the corpus cavernosum by Western blot and immunohistochemistry.
RESULTSThe serum T level was significantly decreased in the rats of the castration group as compared with those of the control and TR groups ([0.41 ± 0.04] vs [16.01 ± 1.02] and [15.84 ± 1.32] nmol/L, P < 0.01), with no statistically significant difference between the latter two groups. The ICPmax/MAP at 0 V, 3 V, and 5 V electric stimulation was remarkably lower in the rats of the castration group (0.088 ± 0.014, 0.323 ± 0.014, and 0.432 ± 0.012) than in those of the control group (0.155 ± 0.011, 0.711 ± 0. 010, and 0.819 ± 0.024) and TR group (0.153 ± 0.012, 0.696 ± 0.017, and 0.763 ± 0.027) (P < 0.01), with no significant difference between the latter two groups. With GAPDH as internal control, the animals of the castration group showed markedly reduced expressions of S1P1 ([49.99 ± 3.39]%), eNOS ([46.82 ± 3.81]%) , and P-eNOS ([45.42 ± 4.35]%) in comparison with those in the control group ([72.57 ± 3.06], [89.76 ± 3.98], and [82.53 ± 8.92] and TR group ([71.77 ± 4.43], [87.19 ± 4.23], and [79.82 ± 7.38]%) (P < 0.01) , while the expressions of S1P2, S1P3, ROCK1, and ROCK2 were significantly upregulated in the castration group ([82.35 ± 4.13], [61.03 ± 5.14], [74.50 ± 4.02], and [69.83 ± 5.75]%) as compared with those in the control group ([41.67 ± 1.68], [31.66 ± 2.67], [35.69 ± 5.56], and [39.85 ± 7.17]%) and TR group ([42.80 ± 3.87], [32.25 ± 4.22], 38.06 ± 5.21], and [42.36 ± 4.44]%) (P < 0.01).
CONCLUSIONAndrogen deficiency induces significant reduction of ICPmax/ MAP in male rats, which is possibly associated with the decline of S1P1 in the corpus cavernosum, inhibition of the eNOS/NO/cGMP signaling pathway, increased expressions of S1P2 and S1P3, and activation of the RhoA/Rho kinase signaling pathway.

Objective To compare the roles of Toll-like receptor 4 (TLR4)/NF-κB signal pathway in acute lung injury (ALl) induced by blunt chest trauma and by blunt chest trauma-hemorrhagic shock and resuscitation (double hits) in rats.Methods Forty male Sprague-Dawley rats,aged 8 weeks,weighing 240-280 g,were randomly assigned into 3 equal groups (n =10 each) using a random number table:sham operation group (S group),blunt chest trauma group (T group),and blunt chest trauma and hemorrhagic shock and resuscitation group (group THSR).Lung contusion was induced in anesthetized rats by dropping a 300 g weight onto a precordial protective shield to direct the impact force away from the heart and toward the lungs.Blood was withdrawn via the femoral artery 5 min later until MAP was decreased to 35-45 mmHg within 15 min and maintained at this level for 60 min,followed by resuscitation.At 6 h after the model was established,the arterial blood samples were collected for blood gas analysis and detection of tumor necrosis factor-alpha (TNF-α) concentrations in serum.Oxygenation index (PaO2/FiO2) was calculated.The rats were then sacrificed and pulmonary specimens were obtained for determination of TLR4 expression and NF-κB ac tivity (by immunohistochemistry and Western blot) in lung tissues and for microscopic examination.Results Compared with group S,PaO2 and PaO2/FiO2 were significantly decreased,PaCO2 and TNF-α concentrations in serum were increased,TLR4 expression was up-regulated,and NF-κB activity was enhanced in T and THSR groups (P < 0.05).Compared with group T,PaO2 and PaO2/FiO2 were significantly decreased,PaCO2 and TNF-α concentrations in serum were increased,TLR4 expression was up-regulated,and NF-κcB activity was enhanced in THSR group (P < 0.05).The histopathological damage to lung tissues was aggravated in THSR group as compared with T group.Conclusion The role of TLR-4/NF-κB signal pathway in ALI induced by blunt chest traumahemorrhagic shock and resuscitation (double hits) is significantly stronger than that in ALI induced by blunt chest trauma alone in rats.

OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.
METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.
RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).
CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

Objective To observe the effect of low arsenic sub-chronic exposure on blood routine test index in rabbits to pave a way for screening early injury of the low arsenic exposure. Methods Twelve healthy male rabbits were randomly divided into four groups. They were administrated with As at the concentration of 0(control), 10, 50 and 250 μg/L in the drinking water. Blood samples were collected from the vein of the ear edge in 8 weeks, and blood test routine including leukocyte (WBC), lymphocyte (LYM), lymphocyte percentage (LYM%), neutrophil (GRA), neutrophil percentage (GRA%), monocyte (MON), monocyte percentage (MON%), red blood cell (RBC), hemoglobin (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin content (MCH), mean corpuscular hemoglobin concentration(MCHC), RDW, platelets(PLT), mean platelet volume(MPV), platelet hematocrit(PCT) and platelet distribution width (PDW), were detected by the ABX-60 hemocyte analyzer. Results Compared with the control group, the WBC, GRA and GRA% increased in 0, 50 and 250 μg/L groups, but there was no significance(P > 0.05). PLT and MPV had a statistical significance in 4 groups(F = 4.07,4.20, all P < 0.05). Compared with the control group[(292.00±16.97)×109/L, (7.10±0.99)fL], PLT decreased in the 250 μg/L group [(221.33±22.50)×109/L] and MPV decreased in the 50μg/L group [(5.57±0.46)fL] significantly (P < 0.05). The other index didn't change obviously. Conclusions Sub-chronic low level arsenic exposure may lead to the change in the blood system. The blood routine test may be considered for early injury of the arsenic poisoning.
