Objective To observe the effect of different thyroid hormone level on the expression of synaptotagmin Ⅰ(Syt Ⅰ) in adult rat hippocampus. Methods All 28 adult male SD rats were assigned randomly into hypothyroid, hyperthyroid and control group, hypothyroid group was established by daily intraperitoneal injections with propylthiou raci(PTU, 10.0 mg/kg body weight) for 6 weeks and hyperthyroid group with L-Thyroxine (L-T4, 0.5 mg/kg body weight) for 3 weeks. Radioimmunity method was used to assay the levels of serum T3 and T4, immunohistochemical S-P technology to assay the levels of Syt Ⅰ protein in hippoeampus CA1, CA3 and dentate gyrus (DG). The layers analyzed in the different subfields include the polymorphic cell layer(the stratum oriens, SO), pyramidal cell layer(PCL), stratum radiatum (SR), lacunosum-molecular layer (SLM) in CA1 and CA3, granular cell layer(GL) and molecular layer(ML) in DG. Results The levels of serum T3 and T4[(0.34±0.12), (41.03± 11.37)nmol/L]in the hypothyroid rats were significantly lower than those in the control group[(0.65±0.15), (55.20±10.68)nmol/L, P < 0.01 or < 0.05], and the positive granule of Syt Ⅰ was significantly lower in PCL and SR of CA1 and CA3, GL of DG. The average optical value responsible for Syt Ⅰ immunoreactivity was obviously reduced in SO(0.048±0.007), PCL(0.299±0.035), SR(0.042±0.007), SLM(0.038±0.006) of CA1, PCL(0.085± 0.019), SR(0.040±0.011), SLM (0.038±0.006) of CA3, GL (0.076±0.019) of DG than normal controls (0.068± 0.014, 0.376±0.053, 0.053±0.008,0.056±0.009,0.118±0.026,0.052±0.010,0.053±0.009,0.099±0.015; P< 0.01 or < 0.05). Serum T3 and T4 levels [(1.43±0.30), (157.18±19.95)nmol/L]of hyperthyroid rats were significantly higher than those of control group(P < 0.01). The value was reduced in PCL(0.322±0.050), SR(0.039±0.006), SLM (0.042±0.006) of CA1, PCL(0.098±0.034), SR(0.046±0.013), SLM(0.046±0.010) of CA3 and GL(0.085± 0.024), ML (0.042±0.009) of DG (P < 0.05 or < 0.01). Conclusion Adult-onset of hypothyroidism and hyperthyroidism can reversibly decrease the expression of Syt Ⅰ in CA1, CA3 and DG regions of hippocampus.

OBJECTIVETo evaluate clinical efficacy of electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery on postoperative pain and discomforts in patients with mixed hemorrhoids.
METHODSOne hundred and twenty cases of mixed hemorrhoids who received Milligan-Morgan operation were randomly divided into an electroacupuncture group, a sham electroacupuncture group and a blank group, 40 cases in each one. At the same time of basic treatment, the electroacupuncture was applied at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery in the electroacupuncture group, while shallow needling without electrical stimulation at sham acupoint (1 cm next to acupoint) was applied 30 min before surgery in the sham electroacupuncture group, while no treatment was given before the surgery in the blank group. The total dose of painkillers in the first 24 h after operation, the number of cases who received additional anesthetic in the operation, the self-score of most severity pain in the first 24 h after operation and sleeping time in the night of surgery were observed.
RESULTSThe differences of the numbers of cases who received additional anesthetic in the operation had no statistical significance among the three groups (all P > 0.05), but compared with the sham electroacupuncture group and blank group, the total dose of painkillers in the first 24 h after operation was reduced in the electroacupuncture group [(2.43 +/- 1.08) tablets vs (3.23 +/- 1.33) tablets, (3.10 +/- 1.22) tablets], and the score of most severity pain was also decreased (6.65 +/- 1.00 vs 7.48 +/- 0.96, 7.25 +/- 1.19), besides, the sleeping time in the night of surgery was increased [(220.63 +/- 85.50) min vs (162.00 +/- 92.69) min, (151.50 +/- 80.01) min, all P < 0.05].
CONCLUSIONThe electroacupuncture at Changqiang (GV 1) and Chengshan (BL 57) 30 min before surgery has effects of preemptive analgesia on postoperative pain for patients with mixed hemorrhoids.

OBJECTIVETo evaluate the therapeutic effect on pain in the dressing change after perianal abscess surgery treated with warm suspending moxibustion at Changqiang (GV 1).
METHODSOne hundred and sixty patients were randomized into a moxibustion group and a far-infrared therapy group, 80 cases in each one. In the moxibustion group, the warm suspending moxibustion at Changqiang (GV 1) was applied. In the far-infrared therapy group, the infrared ray was radiated at Changqiang (GV 1). The treatment started in 10 min after dressing change in the two groups. Totally, 8 treatments were required. The time requirement being equal to or less than 2 score in the assessment face scale (AFS), the case number of pain relief in 10 min after treatment and the intention of the two therapies after everyday dressing change were observed in the patients of the two groups.
RESULTSIn the moxibustion group, the time of pain relief was shorter than that of the far-infrared therapy group [(11.5 +/- 3.9) min vs (17.8 +/- 3.8) min on the 1st day; (9.4 +/- 3.6) min vs (15.2 +/- 4.3) min on the 2nd day; (7.8 +/- 2.7) min vs (14.3 +/- 3.2) min on the 3rd day; (6.4 +/- 3.3) min vs (10.5 +/- 2.9) min on the 4th day; (5.9 +/- 2.9) min vs (11.2 +/- 1.9) min on the 5th day; (5.3 +/- 2.2) min vs (8.8 +/- 2.3) min on the 6th day; (5.4 +/- 1.8) min vs (9.2 +/- 2.1) min on the 7th day; (5.1 +/- 1.4) min vs (9.5 +/- 2.6) min on the 8th day, all P < 0.05]. The case numbers of pain relief in 10 min after treatment were 74 cases, 75 cases, 77 cases and 78 cases from the 1st to the 4th day separately in the moxibustion group, which were much more than 63 cases, 65 cases, 68 cases and 69 cases in the far-infrared therapy group (all P < 0.05). The treatment intention scores in the moxibustion group were better than those in the far-infrared therapy group (all P < 0.05).
CONCLUSIONThe warm suspending moxibustion at Changqiang (GV 1) relieves pain rapidly in the dressing change of much more patients after perianal abscess surgery in much shorter time as compared with the far-infrared therapy. Moreover, the patients have more expectation to be treated with moxibustion therapy.

Objective To discuss the diagnosis and early intervention treatment of fetal congenital broncho-genic cysts based on the cases reviewed. Methods The clinical features of 7 infants presenting bronchogenic cysts diagnosed antenatally from January 2013 to May 2014 in Guangdong Women and Children's Hospital and Health In-stitute were reviewed retrospectively. Pathology,the prenatal diagnosis and treatment of bronchogenic cysts experience were summarized combined with CT after birth and surgery. Results Based on the prenatal diagnosis of fetal and postnatal CT and surgical pathology,a total of 7 cases with congenital bronchial cysts were diagnosed. Of which 4 ca-ses were suggestive of congenital cystsic adenomatoid malformation by prenatal diagnosis,and the other 3 cases had fetal bronchial cysts by prenatal diagnosis,antenatal diagnosis was accurate in 42. 9%(3 / 7 cases). CT examinations were taken in 7 cases after birth,and the cyst excision was performed on them with surgery thoracic approach;the average age at surgery was(5. 3 ± 1. 7)months. Four cases had simple bronchial cystss,2 cases with congenital cystsic adenomatoid malformation,1 case with congenital pulmonary sequestration. The accuracy of CT diagnosis was 85. 7%(6 / 7 cases). All surgical treatment was effective. Conclusions Fetal bronchial cysts is always associated with the other presence of lung congenital malformations. Prenatal diagnosis of congenital bronchial cysts is difficult. Prenatal diagnosis is difficult to exclude congenital cystsic adenomatoid malformation. To avoid symptoms like oppres-sion,infection,prenatal diagnosis combined with CT examination after birth and early treatment are necessary and reliable clinically.

The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.

Objective To analysis the inherent quality of highly cited papers published in Chinese Journal of Endemiology, so as to identify the direction of invitation for contributions, find high quality articles, and to improve the journal's core competitiveness. Methods Scientific papers published in Chinese Journal of Endemiology from 2000 to 2006, with citation rate equal to or higher than 20 times were retrieved in China National Knowledge Infrastructure(CNKI) by December 27, 2010. These articles were statistically analyzed according to publication year, section type, author, and geographical distribution of units. Results A total of 68 highly cited papers were obtained. The citation frequency of the highly cited papers ranged from 20 to 94, with an average of 31.09 times. The highly cited papers were published in 2000 at most, accounting for 25.0%(17/68); followed by 2001,accounting for 20.6% (14/68); at least in 2006, accounting for 2.9% (2/68). Of the highly cited papers, experimental study articles was in the highest proportion of 30.9%(21/68); followed by field epidemiological investigation articles,accounting for 23.5%(16/68); editorial, review articles accounting for 10.3%(7/68) and 8.8%(6/68), respectively;short reports, case reports, meeting records etc were not highly cited papers. The number of highly cited papers in editorial, expert forums, academic contend accounted for higher proportion of total number in corresponding section types(7/19, 3/11, 3/7). Highly cited papers came from 13 provinces(municipalities), there were 10 authors contributed two or more highly cited papers, and 8 units contributed two or more highly cited papers. Conclusions Adequate space should be given to experimental research, field epidemiological investigation, editorial, expert forums andacademic contend articles due to their high rate of citation. More attention should be paid to further consolidate and expand excellent authors group, and to intensify the invitation for key issues from influential experts.

OBJECTIVETo evaluate the effect of non-surgical periodontal therapy on periodontal status, glycemic control and the level of serum interleukin (IL)-6 in type 2 diabetic patients with chronic periodontitis (DMCP).
METHODSFifty-five DMCP and 55 systemically healthy patients with chronic periodontitis (CP) were recruited in this study. The diabetes were classified into two groups, the well-controlled group [glycated hemoglobin (HbA1c) < 7.00%] and the poorly controlled group (HbA1c ≥ 7.00%). All subjects received non-surgical periodontal therapy. Periodontal clinical parameters including periodontal probing depth(PD), attachment loss (AL), bleeding index (BI) and plaque index (PLI) were recorded at baseline, 6 weeks and 3 months after the treatment. Fasting plasma glucose (FPG), HbA1c and the concentration of serum IL-6 were measured.
RESULTSAt 6 weeks and 3 months after treatment, PD, AL, BI, PLI and the concentration of serum IL-6 of both groups significantly reduced (P < 0.05). The level of IL-6 in diabetic patients reduced significantly from (3.47 ± 0.33) ng/L to (3.21 ± 0.66) ng/L and to(3.03 ± 0.54) ng/L. The HbA1c of diabetic patients reduced significantly 3 months after treatment [(6.80 ± 1.21%] compared with the baseline [(7.35 ± 1.73)%, P < 0.05]. HbA1c of the poorly controlled group reduced significantly (P < 0.05), while HbA1c of the well-controlled diabetes did not show any apparent reduction (P > 0.05).
CONCLUSIONSNon-surgical periodontal therapy can effectively reduce the concentration of serum IL-6, thereby improving glycemic control in type 2 diabetes patients with chronic periodontitis. However, there was no any significant reduction of HbA1c in the well-controlled diabetes.
