Objective:To evaluate the effect of icariin on TNF-αexpression in periodental tissue during root resorption induced by ropid palatal expansion in rats.Methods:24 male Wistar rats were divided randomly into 3 groups(n =8)as group A(none-expansion control group),B(expansion group)and C(icariin and expansion group).In group B and C,an initial force of 50 g was applied to the area between the right and left upper first molars of the rats for 2 weeks for palatal expansion.The rats of group C were given intragastric administration of icariin at 2.5 mg/(kg·d)while the rats of group A and B were given the same dose place-bo.The centered buccal-lingual root and peridentium tissue slices were generated from the upper first molars of the rats.HE stai-ning of the slices was performed.The expression of TNF-αprotein at the compression sites was detected by irnmunohistochemistry. Results:The A values of TNF-αof group A,B and C were 0.030 2 ±0.001 7,0.241 0 ±0.002 4 and 0.088 6 ±0.002 8 respec-tively(B vs A or C,P <0.05).Conclusion:Icariin may inhibit TNF-αexpression in periodental tissue during root resorption in-duced by rapid palatal expansion.

Objective:To explore the expression of miR-139-5p in small cell lung cancer (SCLC)tissue and its clinical significance, and to clarify the role of miR-139-5p in the occurrence and development of SCLC. Methods:The biological function of miR-139-5p was examined by cell growth,apoptosis and cell cycle analysis. The expressions of miR-139-5p in 50 cases of cancer tissue and paracarcinoma normal tissue were examined by QRT-PCR.Combined with the clinical data,the role of miR-139-5p in clinic was anzlyzed.Results:The expression level of miR-139-5p in SCLC tumor tissue was lower than that in normal lung tissue (P <0.01).The expression level of miR-139-5p in the cells was un-regulated significantly after transferred miR-139-5p mimics (P <0.01).Compared with control group,the proliferation abilitiy of cells was reduced after up-regulating the expression of miR-139-5p (P < 0.01),the number of cells at G1 phase was increased (P < 0.05),and the cells were arrested at G0/G1 phase.The miR-139-5p expression was not associated with gender and age (P > 0.05).The expression level of miR-139-5p in the patient at LD stage was lower than that of the patients at ED stage (P <0.01).The expression level of miR-139-5p in the resistant patients was higher than that of the patients sensitive to chemotherappy (P <0.01).The expression level of miR-139-5p in the survival patients was lower than that in the death patients (P <0.01).Cox regression analysis indicated that miR-139-5p expression and disease stage were the independent prognostic factors for SCLC.Conclusion:miR-139-5p in participates in the occurrence and development of SCLC by inhibiting the cell proliferation,promoting apoptosis and inducing the cell cycle arrest;it may be used as a target gene to evaluate the prognosis of SCLC patients.

The body surface area of adult Chinese males was estimated by using paper cast method.56 healthy individuals, aged 18 to 45, coming from thirteen provinces mostly from Hebei and Hubei were used in this study. From the results obtained, the mean body weight, height and surface area were 59.78kg, 168.8 cm and 1.712 m2 respectively. A height-weight equation for estimating body surface area was derived accordingly, i.e. body surface area(m2)= 0.00607H(cm) + 0.0127W(kg)-0.0689. The error of the value calculated from the equation was 0.17% higher than the value actually taken on an average. The percentage of various body regions to the total body surface area was as follows: head, 6.11; trunk (including neck), 29.59; upper arms, 8.09; forearms, 6.41; hands, 4.93; thighs (including buttock), 24.63; calf, 13.29 and feet, 6.95.For convenient use a table for calculation was given.

Background: Although there are some Chinese herbal medicines in treatment of constipation, but no multi-center randomized controlled trials have been carried out to prove their effectiveness. Objective: To evaluate the safety and efficacy of Yunchang Capsule in treatment of functional constipation with deficiency of both qi and yin and internal accumulation of poisonous pathogenic factors syndrome, and to explore the clinical dosage. Design, setting, participants and interventions: A randomized, double-blinded controlled, multicenter trial was conducted. A total of 240 patients with functional constipation from West China Hospital of Sichuan University, Affiliated Hospital of Chengdu University of Traditional Chinese Medicine, Affiliated Hospital of Jiangxi University of Traditional Chinese Medicine, the First Affiliated Hospital of Tianjing University of Traditional Chinese Medicine and Fujian Academy of Traditional Chinese Medicine were randomly divided into three groups: low dose group (80 cases), high dose group (80 cases) and control group (80 cases). Patients in the low dose group were treated with two pills (0.35 g/pill) of Yunchang Capsule and one pill of Yunchang Capsule simulant for three times daily; patients in the high dose group were treated with three pills (0.35 g/pill) of Yunchang Capsule for three times daily; and patients in the control group were treated with three pills (0.35 g/pill) of Biantong Capsule for three times daily. The therapeutic course was 14 days. Main outcome measures: Clinical symptoms, syndromes, and adverse effects were observed before and after the treatment, and blood, urine and stool tests, hepatorenal function and electrocardiogram were also examined. Results: Two cases were excluded, eleven cases were lost to follow-up, and there were 234 patients entered to intention-to-treat (ITT) analysis. After the treatment, the therapeutic effects were calculated by full analysis set (FAS) and per-protocol population set (PPS) analysis respectively. The effects on functional constipation in FAS showed the response rates in the low dose, high dose and control groups were 86.25% (69/80), 82.90% (63/76), and 70.52% (55/78) respectively, and PPS analysis showed the response rates were 85.71% (66/77), 83.56% (61/73), and 70.13% (54/77) respectively. There were no significant differences among the three groups (P>0.05). The effects on traditional Chinese medicine syndrome in FAS showed the response rates in the low dose, high dose and control groups were 78.75% (63/80), 69.74% (53/76), and 67.95% (53/78) respectively, and PPS analysis showed the response rates were 77.92% (60/77), 69.87%(51/73), and 67.53% (52/77) respectively. There were also no significant differences among the three groups (P>0.05). No severe adverse events were observed. Conclusion: Both low dose and high dose of Yunchang Capsule are effective and safe in treatment of functional constipation with deficiency of both qi and yin and internal accumulation of poisonous pathogenic factors syndrome.

We had previously reported the height-weight formula for the estimation of body surface area of adult Chinese males (this journal 6(2):87, 1984). In this study, by using the same paper cast method, a formula for the adult Chinese females was obtained from the data of 44 healthy subjects (age 18-45) coming from 15 provinces. The mean body weight, height and surface area measured were 52.13?6.22 kg, 159.3?5.18 cm and 1.546?0.105 m2 respectively. The formula thus derived was: body surface area (m2) = 0.00586H (cm) +0.0126W (kg)-0.0461. The value calculated from it was 0.03% less than the value actually measured on an average. The percentage of various body regions to the total body surface area was as follows: head, 6.33; trunk (including neck), 28.27; upper arms, 8.29; forearms, 6.65; hands, 4.52; thighs (including buttocks), 27.40; calves, 12.83 and feet, 6.65.

Objective To investigate the pathogen characteristics of perforated appendicitis in children and the perioperative use of antimicrobials in order to provide evidence for the rational use of perioperative antibiotics. Methods The perioperative usage of antibiotics was analyzed to determine the reasonableness of antimicrobial use in children with perforated appendicitis who were discharged from July 2011 to August 2014,based on“guidelines of clinical use of antibiotics”and results of bacterial culture. Results Inflammatory secretions obtained from 126 children(126/ 149)were sent for examination and the examination rate was 84.56%.A total of 117 cases were found positive for cultured pathogens,and the detection positive rate was 92.86%.Three types of bacteria ranking the first three places were Escherichia coli,Pseudomonas aeruginosa and CitroBacter freundii.The utilization rate of antibacterial agents was 100.00%,with a dominant use of cephalosporins and nitrate imidazoles. Rational use of antimicrobial agents was found in 144 cases(accounting for 96.64%). Conclusion The major pathogen in perforated appendicitis is still Escherichia coli,which is highly sensitive to commonly used antibiotics,and drug-sensitivity testing results can help guide the treatment programs and antibiotics selection.
