Objective To investigate the expression and clinical significance of the estrogen receptor beta isoforms and survivin in thyroid tumors. Methods The pathological data of 125 patients with thyroid tumors were, collected from june 2003 to june 2007 in our institution, including thyroid carcinoma (86 cases), thyroid follicular adenoma (39 cases) and normal thyroid tissue (10cases). SP immunohistochemistry was used to measure the expressions of ERβ and survivin in the thyroid tumors. Results ERβ not only was detected in the thyroid epithelial cell plasma and nuclear, but also in the stroma. The positive rate of ERβ in cases with thyroid carcinoma, adenoma and normal thyroid tissue were 83.72 %, 51.28 % and 20.00 % respectively. There was significant difference between carcinoma and the adenoma or normal thyroid tissue (P<0.05). The positive rate of survivin in cases with carcinoma, adenoma and normal thyroid tissue were 59.30 %, 17.95 % and 0 respectively. There was significant difference between carcinoma and the adenoma or normal thyroid tissue (P<0.05). The expressions of ERβ and survivin correlated with TNM staging and lymph node metastasis of thyroid carcinoma (P<0.05). Conclusion ERβ may play a role in accelerating proliferation in the occurrence of the thyroid carcinoma. The expressions of ERβ and survivin are related to invasion and metastasis of thyroid carcinoma.

Objective To observe the time-effect relationship between acupuncture treatment and the absorption of cerebral hematoma and edema in the acute stage of cerebral hemorrhage to determine the optimal time for acupuncture intervention in cerebral hemorrhage.Methods Three hundred patients with cerebral hemorrhage in the acute stage were randomly allocated to treatment groups 1, 2, 3 and 4, and control group, 60 cases each. The control group received symptomatic treatment for regulating blood pressure, reducing intracranial pressure by dehydration, maintaining electrolyte balance, nourishing nerves and preventing and treating complications. The treatment groups were given acupuncture in addition. Treatment group 1 received acupuncture at 24 hrs after the attack; treatment group 2, at 72 hrs; treatment group 3, at one week; treatment group 4, at two weeks. Pre-/post-treatment hematoma size parameter difference value and cerebral peripheral edema grade parameters were observed in every group.Results There were statistically significant pre-/post-treatment differences in hematoma size and cerebral edema grade in every group (P<0.01,P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between every treatment group and the control group (P<0.05). There were statistically significant post-treatment differences in hematoma size and cerebral edema grade between treatment group 1, 2 or 3 and treatment group 4 (P<0.05), between treatment group 1 or 2 and treatment group 3 (P<0.05) and between treatment groups 1 and 2 (P<0.05).Conclusions Acupuncture has a positive therapeutic effect in patients with cerebral hemorrhage in the acute stage. The earlier acupuncture intervention in the acute stage of cerebral hemorrhage, the more remarkable the effect.

The efectienes of acpuncture for smoking cessation was systematically evaluated in this paper. By using computer retrieval in Chinese national knowledge infrastructure (CNKI), WANFANG database, VIP database, PubMed, ScienceDirect and Springer, the randomized controlled trials (RCTs) regarding acupuncture for smoking cessation from January of 1983 to December of 2013 were collected; by using Table of Standardized Report Factors for Acupuncture RCTs, each inclusive RCT was evaluated; and by using RevMan 5. 2 software, the Meta-analysis was performed. Totally 24 RCTs were included, involving 3084 cases of smoking. The result of literature quality assessment showed that the average score was 25. 71 points without low-quality RCT which had a score of less than 16 points. The Meta-analysis showed that acupuncture could significantly increase the short-time abstinence rate [RR=1. 48, 95% CI (1. 18,1. 84), Z=3. 47, P<0. 0005] and number of cigarettes smoked daily [RR=4. 35, 95% CI (2. 03, 6. 66), Z=3. 68, P<0. 001] and FTND [RR=2. 37, 95% CI (1. 88, 2. 86), Z= 9. 44, P<0. 00001], however, it could not increase the long-time abstinence rate [RR=1. 40, 95% Cl (0. 90, 2.17), Z=1. 49, P>0. 05]. Compared with other treatment, acupuncture has positive advantages on short-time abstinence rate, however, its effect on long-time abstinence rate needs to be verified by high-quality, large-sample and multi-center RCT in the future.

Annulate lamellae (AL) in oocytes of eel, Anguilla japonica have been observed with electron microscopy. Two types of AL have been found in the cytoplasm of these cells, one of which is the common type, characterized by a stack of parallelly arranged lamellae with annuli (or rings) as shown in figure 1, another is a rare one, which appears as alternative arrangement of parellel lamellae with annuli and membrane-like structures as shown in figures 2～4. The only difference between them is the presence of membrane-like structure in the latter. The origin and function of the membrane-like structure have not been found out yet. It is suggested that this structure might be similar to above-mentioned lamellae in origin and might be a "buffer" in function.

Objective To observe the effect of acupuncture on the expression of nitricoxide synthase (NOS) in gastrointestinal tissues after operation for incomplete intestinal obstruction in rats, and to explore the mechanism of acupuncture in promoting the recovery of gastrointestinal motility. Methods Forty Sprague-Dawley (SD) rats were randomized into treatment group 1, treatment group 2, model group 1, model group 2, and a normal control group, 8 rats in each group. The incomplete intestinal obstruction models were developed by using single ligation method in treatment groups and model groups. Afterwards, the treatment groups were intervened by acupuncture at Zusanli (ST 36) and Yanglingquan (GB 34), and rats in treatment group 1 and 2 were respectively dissected after 1-day and 2-day treatment. The rats in model group 1 and 2 were respectively dissected 1 d and 2 d after modeling. The morphological observation was performed on rat’s intestinal tissues, and the average diameter of the upper part of the obstructed intestine and the expression of NOS in gastrointestinal tissues were compared. Results The average ileocecal diameter after modeling was significantly different from that in the normal control group (P<0.05). There was a significant difference in comparing the ileocecal diameter between model group 1 and 2 (P<0.05). The ileocecal diameter in treatment group 1 was significantly different from that in treatment group 2 and model groups (P<0.05). The ileocecal diameter in treatment group 2 was insignificantly different from that in the normal control group (P>0.05). The NOS content in model groups was significantly different from that in the normal group (P<0.05). The NOS content in treatment group 1 was markedly different from that in model groups and treatment group 2 (P<0.05) after intervention. There were no significant inter-group differences in comparing NOS content (P>0.05). Conclusions Acupuncture can promote the recovery of gastrointestinal motility by regulating intestinal NOS content in rats after operation for incomplete intestinal obstruction.

Polysaccharide sulfate (PSS) is a new type of antiatherosclerotic medicine for its effects of anticoagulation, anti-thrombosis and modulation of dyslipidemia. However, it is still uncertain whether PSS could modulate the diabetic dyslipidemia or not. Here, the rat model of diabetic dyslipidemia was developed and the effects of PSS on glucose and lipid levels were investigated in this animal model. Wistar rats were iv injected with streptozotocin 20 mg·kg-1 after feeding with high fat diet for one and a half month. Then, rats received orally PSS (30, 90, and 180 mg·kg-1) for 1 month. After oral treatment with PSS (90 and 180 mg·kg-1) for 1 month, the levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol (LDL-C) were significantly reduced and the level of high density lipoprotein-cholesterol (HDL-C) increased, compared with diabetic control rats. Moreover, PSS (30, 90, and 180 mg·kg-1) had a tendency to reduce glucose and insulin levels, and significantly increased insulin sensitivity index. Our results suggest that PSS could improve insulin sensitivity and relieve dyslipidemia in diabetic dyslipidemic rats.

Aim To explore the pharmacological mechanism and the effects of polysaccharide sulfat(PSS) on cardiovascular diseases induced by type 2 diabetes mellitus(DM) through observing the risk factors.Methods Type 2 diabetic animal model was established by high-sugar and high-fat diets,combined with injection of small amount streptozotocin(STZ 20 mg?kg-1,iv).Adult male wistar rats were divided into five groups: normal control group,model group,polysaccharide sulfate group,metformin group and lovastatin group.They were treated with exact medicne for 8 weeks,but control group and model group were treated with 0.9% Nacl.During this process,FBG and serum lipid concentrations were measured.22 weeks later,the rats were sacrificed.The activity of tissue-type plasminogen activator(t-PA) and plasminogen activator inhibitor type-1(PAI-1) were detected by chemical methods.The aortas were collected for histopathlogical,immunohistochemical and Western blot studies.Results FBG concentrations and serum lipid(TC,TG,LDL) levels decreased in PSS group as compared from those of model group(P

Objective To clone the coding region and 3′non?coding region of calmodulin 2(CaM2)in guinea pig,to provide the genetic informa?tion for studying the gene function of Calmodulin 2. Methods Total RNA was extracted from heart tissue of guinea pig,the coding region and 3′non?coding region of CaM2 were amplified by RT?PCR and 3′?RACE PCR methods,and the recombinant plasmid was constructed by inserting cDNA of the coding region and 3′non?coding region of CaM2 into the cloning vector by genetic engineering technology followed by DNA sequencing and se?quence analysis. Results The cloned coding region of CaM2 was 450 bp,and the 3′non?coding region of CaM2 was 660 bp. The amino acid se?quences of the coding region of CaM2 was consistent with those of other CaM subtypes,and the 3′non?coding region of CaM2 had low homology with those of other subtypes. Conclusion The cloning of CaM2 coding region and 3′non?coding region in guinea pig was the foundation for further study on the gene function of CaM2 and its role in related diseases.

Objective To investigate the correlation between reproductive hormone concentration and the amplitude and latency of speech-evoked auditory brainstem response (speech-ABR) in young adults, and to explore the effects of reproductive hormone on the speech processing ability of young people.Methods Speech-ABR of thirty five normal hearing young adults, including seventeen females (27.29±1.83 years old) and eighteen males (28.17±2.50 years old) were recorded.The speech syllable /da/ was transmitted as a stimulus sound to the right ears through insert earphones in speech-ABR test.All participants had air conduction hearing thresholds of 20 dB HL or better across the standard audiometric frequencies (250~8 000 Hz) in both ears, and click-ABRs were also within normal limits.At the same time, the concentrations of estradiol and testosterone in the serum were examined.Results ① Females had a shorter latency than males in transient responses (waves V, A and O) and sustained responses (waves D, E and F) of speech-ABR (P<0.05, respectively).The amplitude of transient response (waves V and A) and sustained response (waves D, E and F) in females was also significantly larger than that in males (P<0.05, respectively), except for amplitude of peak O (P>0.05).The V/A slope in females was significantly steeper than that in males (P<0.05).② Estradiol levels in females (118.77±102.66 pg/ml) were significantly higher than that in males (52.91±14.77 pg/ml) (P<0.05), and the total testosterone concentration in females (457.65±140.82 pg/ml) was significantly lower than that in males (3 677.37±1 155.80 pg/ml) (P<0.05).③ A correlation analysis between speech-ABR and estradiol or total testosterone showed that all peak latencies of speech-ABR in transient responses (waves V, A and O) and sustained responses (waves D, E and F) were negatively correlated with the estradiol concentration (P<0.05 respectively), in which the correlation coefficient was between 0.2~0.4.All peak latencies of speech-ABR were positively correlated with the total testosterone concentration (P<0.05 respectively), in which the correlation coefficient was between 0.4~0.7.④ The amplitudes of speech-ABR increased with estradiol concentration growing, the wave V and estradiol concentrations were positively correlated (P<0.05).The estradiol concentrations showed a significant negative correlation with wave A, D, E, F and O wave (P<0.05 respectively), with a correlation coefficient between 0.2~0.7.On the contrary, the amplitudes of speech-ABR decreased with the increasing of total testosterone concentration, and the wave V, wave A, V/A slope and total testosterone concentration were moderately correlated (P<0.05),with a correlation coefficient between 0.4-0.6.The correlation between the amplitudes of D wave and total testosterone concentration was not statistically significant (P>0.05), and the correlation between wave E and wave F and total testosterone concentration was weakly correlated (P<0.05).In addition, the amplitudes of the wave O were also independent with testosterone levels (r=0.133, P>0.05).Conclusion There are correlations between the level of reproductive hormone and the amplitude and latency of speech-ABR.It is one of the reasons for the gender difference in the brainstem speech coding ability of normal young adult.
