Objective:To study parenting style of difficultly educated children and the state of their mental health.Methods:Randomly select 120 difficultly educated children from a Training Camp in Changsha and used SCL-90 and EMBU to rate their parenting style and mental health.Results:The mental health condition of difficultly educated children was significantly worse than the norms,but the normal middle school students parental warmth was higher than the difficutly educated students.Difficultly educated children scored significantly higher in father's firm control,punishment,over interference,rejection and denial and maternal rejection and denial,firm control and punishment,but significantly lower in parental warmth.Conclusion:Difficultly educated children had got more mental problems,and their parents treat them with more negative parenting style and less positive parenting style.

Many Chinese medicinal materials are difficult to be distinguished in characters resulting in easy confusion. In the pa-per, the basic concepts of three groups of easily confused Chinese medicinal materials ( schisandrae chinensis fructus and schisandrae sphenantherae fructus, phellodendri cortex and phellodendri amurensis cortex, akebiae caulis and clematidis armandii caulis) were illus-trated and the development of verification methods were reviewed in the respect of modern instrumental analysis technology. With the improvement of analysis technology, the identification of Chinese medicinal materials relies on experimental data instead of artificial ex-perience, which makes it more objective and accurate.

This review introduced the anti-tumor effects of non-steroid anti-inflammatory drugs (NSAIDs) and summarized their possible molecular mechanisms according to recent abroad literatures and our research results. Some evidence showed that the anti-tumor mechanisms of NSAIDs were different in various tumors.NSAIDs decreased the biosynthesis of PGE_2 and regulated the expressions of downstream correlated genes and proteins through restraining abnormal expression of COX-2 in certain neoplasms,which resulted in the inhibition of tumor angiogenesis and proliferation as well as induced apoptosis. But in other cancer cells, NSAIDs, as activators of peroxisome proliferator-activated receptor ? (PPAR?), induced COX-2 expression, promoted the biosynthesis of cyclopentenone prostaglandins (cyPGs). cyPGs further induced tumor cell apoptosis with PPAR? dependently or PPAR? independently. Since their special mechanisms of anti-proliferation and pro-apoptosis, NSAIDs revealed significant synergistic effects with other anti-tumor treatments.

Objective To investigate the clinical effect of IFNα combined with mannan peptide in treatment of patients with HBeAg-positive chronic hepatitis B ( CHB ). Methods Eighty HBeAg-positive CHB patients with HBV DNA quantity ranging from 10 to 10 eopies/mL were enrolled and randomized into the treatment group and the control group ( n = 40 for each ). Patients in treatment group were given daily subcutaneous injection of IFNα-2b 5,000,000 U for 52 weeks, and received mannan peptide 10 mg per intravenous injection or 2. 5 mg per intramuscular injection for a total of 2 to 3 treatment courses (12 weeks for each). The control group received only IFNα-2b treatment. Liver function, serum markers of hepatitis B, HBV DNA quantity and blood tests were performed before the treatment and at 2, 4, 8, 16, 26 and 52-week during the treatment; and the adverse effects were recorded. Results The rates for ALT normalization, negative HBsAg, negative HBeAg, HBeAg seroconversion and negative HBV DNA were 91. 8% , 17. 5% , 52. 5% , 27. 5 % and 47. 5% at 52nd week in the treatment group, while those in the control group were 80. 0% , 12. 5% , 30. 0% , 10. 0 % and 25. 0% , respectively. There were significant differences in HBeAg-negative, HBeAg-seroeonversion and HBV DNA-negative rates between two groups (χ2 = 4. 178, 4.021 and 4.381, P < 0. 05 ) , and these indexes in the treatment group were increased to 57. 5% , 30. 0% and 50. 0 respectively at 52nd week after drug withdraw. White blood cells began to be elevated at 4th week and were restored to the normal levels at 8th week in the treatment group, while the count in the control was lower than the normal value even at 52nd week of the treatment with the average of (3.45±1. 18)×109/L. Conclusion Alpha-interferon combined with mannan peptide therapy is effective for patients with HBeAg-positive CHB, which may restore the declined peripheral WBC counts induced by interferon and improve the compliance.

Objective To investigate the efficacy of intratympanic methylprednisolone perfusion (IMP) for the treatment of sudden sensorineural hearing loss (SSNHL ) which failed to be fully responsive to conventional treatment .Methods The hearing outcomes of 87 patients with unilateral SSNHL were retrospectively analyzed .All of the patients received IMP after not fully responsive to conventional treatment of varying periods of time .They were hospitalized in our department between January 2008 and December 2012 and were followed up for at least one year to exclude recurrent hearing loss .Results The effective rate was 66 .67% and the mean PTA improvement was (18 .53 ± 13 .54)dB of the patients with the time interval between onset of symptoms and IMP within 15 days , 21 .21% and (5 .92 ± 15 .18)dB of the patients with the interval between 16 and 30 days ,4 .76% and (3 .69 ± 7 .00) dB of the patients with the interval more than 30 days respectively .The significant difference in the effective rates were compared among the three groups(χ2 =25 .91 ,P<0 .01) .Regarding to the PTA improvement ,the group with interval within 15 days was better than the other two groups(F=11 .182 ,P<0 .01) .A total of 30 cases acquired more than 15 dB hearing gain after IMP .One of them was hearing loss in low frequencies and the other 29 cases were hearing loss at all frequencies .The mean hearing gains of the 29 cases in 0 .25 kHz ,0 .5 kHz ,1 kHz ,2 kHz , 4 kHz and 8 kHz were 35 .17 ± 18 .15 dB ,35 .38 ± 15 .90 dB ,31 .28 ± 19 .74 dB ,21 .31 ± 17 .34 dB ,14 .97 ± 16 .00 dB and 13 .80 ± 16 .35 dB ,respectively .The mean hearing gains at lower three frequencies (0 .25~1 kHz)were better than those at higher three frequencies (2 k~8 kHz)(F=9 .494 ,P<0 .01) .Conclusion Receiving IMP earlier might help to acquire better hearing gain for the patients with SSNHL after not fully responsive to conventional treat‐ments .The hearing gains at the lower frequencies were better than those at the higher frequencies after IMP .

BACKGROUND:Corneal lymphangiogenesis is beneficial to the transport of corneal antigenic materials, and accelerates the process of antigen presentation, thereby playing an important role in corneal immunity. However, due to the paral el outgrowth of corneal blood and lymphatic vessels in transplanted corneas, it is often difficult to accurately evaluate the role of corneal lymphatic vessels in allograft rejection. OBJECTIVE:To explore the development of corneal lymphangiogenesis and angiogenesis in transplanted rat corneas after the blockade of vascular endothelial growth factor C (VEGF-C). METHODS:130 rats used to establish corneal al ogenic transplantation models were equally randomized into two groups:the anti-VEGF-C group and the control group. VEGF-C was blocked in the anti-VEGF-C group by intraperitoneal injection of neutralizing monoclonal anti-VEGF-C antibody every other day for 2 consecutive weeks. Meanwhile, rats in control groups received intraperitoneal injections of saline. Corneal angiogenesis and lymphangiogenesis were characterized using whole mount immunofluorescence, and the immune rejection of the grafts was evaluated by scoring the rejection index (RI). In addition, the expression of VEGF-C was examined by real-time PCR. The relationship of corneal lymphangiogenesis and angiogenesis to RI in transplanted corneas was also characterized. RESULTS AND CONCLUSION:VEGF-C expression was markedly downregulated after VEGF-C blockade. Corneal lymphangiogenesis developed in parallel with corneal angiogenesis in the control group. While there was a mild reduction in blood vessel area (BVA) and a significant decrease in lymphatic vessel area (LVA) in the anti-VEGF-C group (P<0.05). In addition, RI was positively correlated with BVA (P<0.05) and LVA (P<0.05) in the control group. However, although RI was significantly correlated with BVA (P<0.05) in the anti-VEGF-C group, the correlation between RI and LVA was not statistically significant (P>0.05). the graft survival time in the anti-VEGF-C group was significantly increased compared with that in the control group (P<0.05). Our results show that the outgrowth of lymphatic vessels is separated from that of blood vessels in transplanted corneas by blocking VEGF-C. The blockade of VEGF-C has a significant role in preventing corneal lymphangiogenesis in corneal beds, which results in higher al ograft survival rates.

Objective To investigate the role of individual dental stent on taste protection in the patients with primary nasopharyngeal carcinoma.Methods Firstly,dosimetric evaluation of the tongue under the circumstance of 10 pairs of patient wearing dental stent or not was done.Secondly,a total of 61 patients were randomized into two arms:29 were in the trial arm and 32 in the control arm.The patients wore dental stent during radiotherapy in trial group,but not in control group.The endpoint was taste dysfunction before radiotherapy,every week during radiotherapy till the completion of radiotherapy,and followed up six months after radiotherapy.Results The mean dose of tip of tongue,body of tongue,base of tongue for patient with dental stent or not were (394.43±24.01) cGy,(986.35±77.15) cGy,(4 401.16±179.01) cGy and (677.03± 110.05) cGy,(2 418.19±414.18) cGy,(4 878.67±387.45) cGy (P value were 0.031,0.007 and 0.284,respectively) separately.By the completion of the radiotherapy,there were 9 (31.03 ％) patients suffering from a taste dysfunction in the trial group and 25 (78.13 ％) in the control group (P ＜ 0.001).Conclusions Individual dental stent has a potential tendency to relieve the taste impairment by reducing the irradiation dose of tongue.
