AlM: To demonstrate the effect of comprehensive treatments for meibomian gland dysfunctional dry eye.
METHODS:Totally, 86 cases (172 eyes) in our hospital, who suffered from meibomian gland dysfunctional dry eye, were measured by BUT, CFS, the machine of infrared meibomian gland function and testing meibomian gland after extrusion. The scores of meibomian gland function missing and secretions were observed, which as a diagnosis, and assessed the effectiveness of treatment, after took comprehensive treatments in different stages ( comprehensive treatments including cleaning, hot covering, massaging, TobraDex, Pranoprofen and Lubricant, etc. ) .
RESULTS:All patients were treated and observed for 3wk, in which 46 cases (92 eyes) of cured, 29 cases (58 eyes) effective, 11 cases (22 eyes) ineffective, the total effective rate was 87. 2%. After 6wk, 68 cases (136 eyes) of cured, 13 cases (26 eyes) effective, 5 cases (10 eyes) ineffective, the total effective rate was 94. 2%, not appeared adverse ocular and systemic reactions in the process of treatment.
CONCLUSlON: Taken comprehensive treatments for meibomian gland dysfunctional dry eye could effectively shorten the course of the disease, quickly remove meibomian gland tube obstruction, restore the meibomian gland secretion and stable the lipid layer, and could reduce the discomfort of patients with dry eye positively and effectively.

AIM: To compare the safety and efficacy of conjunctival autograft transplant ( CAT ) and limbal - conjunctival autograft transplant (LCAT) for primary pterygium.
METHODS: In this prospective, randomized and controlled clinical study, 120 patients ( 120 eyes ) diagnosed with primary pterygium were collected in NO. 474 Hospital of Chinese PLA from January 2014 to January 2015. The 120 patients enrolled in the study in turn, and divided into two group by the odd and even number. The odd number underwent CAT and the even number underwent LCAT.
RESULTS:One hundred and seven patients (107 eyes) completed the follow-up of 1a, including 54 patients (54 eyes) from the CAT group and 53 patients (53 eyes) from the LCAT group. Four patients (4 eyes, recurrence rate 7. 4%) in the CAT group and 2 patients ( 2 eyes, recurrence rate 3. 8%) in the LCAT group developed recurrence. However, there were no significant in recurrence rate between CAT group and LCAT group (P =0. 678).
CONCLUSION: CAT and LCAT might be both effective treatment for primary pterygium for reducing the recurrence rate of pterygium. However, LCAT is the optimal surgical method for primary pterygium.

Objective BRAFV600E mutation, RET/PTC rearrangement, and the concomitant of Hashimoto's thyroiditis(HT) could influence clinicopathological features of papillary thyroid carcinoma (PTC).This study is to investigate the distribution of three factors in PTC and to analyze their associations with clinicopathological characteristics.Methods Fine-needle aspiration samples were collected in a total of 122 conventional PTC patients, who were confirmed by surgery.The clinicopathological features were collected to analyze its association with different factors.BRAFV600E mutation and RET/PTC rearrangement were detected by pyrosequencing and Taqman-qPCR, respectively.Results BRAFV600E mutation was significantly correlated with an older age and a less coexistence with HT(P＜0.05).In contrast, RET/PTC rearrangement was more prevalent in young patients and was associated with the concomitant of HT(P＜0.05).In the age of ≥20 year and＜45 year groups, BRAFV600E mutation was significantly associated with extrathyroidal invasiveness.RET/PTC rearrangement was significantly associated with bilateral lymph node metastasis and the number of metastatic lymph node.Conclusions The distribution of three factors were different in PTC patients.In addition to the age at diagnosis, all of three factors should also be considered together to analyze the association of clinicopathological features of PTC.

Platinum-based anticancer drugs have been becoming one of the most effective drugs for clinical treatment of malignant tumors for its unique mechanism of action and broad range of anticancer spectrum. But, there are still several problems such as side effects, drug resistance/cross resistance and no-specific targeting, becoming obstacles to restrict its expanding of clinical application. In recent years, supramolecular chemistry drug delivery systems have been gradually concerned for their favorable safety and low toxicity. Supramolecular macrocycles-platinum complexes increased the water solubility, stability and safety of traditional platinum drugs, and have become hot focus of developing novel platinum-based anticancer drugs because of its potential targeting of tumor tissues/organs. This article concentrates in the research progress of the new drug delivery system between platinum-based anticancer drugs with three generations of macrocycles: crown ether, cyclodextrin, cucurbituril and calixarene.

PURPOSE: The aim of this study is to evaluate the incidence of de novo malignancy after liver transplantation (LT) and compare with those among the general Chinese population. METHODS: A total of 466 patients who had a minimum follow-up time of 6 months were enrolled in the study. All data of medical records and follow up were retrospectively reviewed. RESULTS: The incidence rate of de novo malignancy was 3.0% (14 in 466 patients). The median elapsed time from transplant to the diagnosis of de novo malignancy was 42 months (range, 6 to 106 months). The cumulative risk for development of de novo malignancy was 1.6%, 2.7%, and 8.2% at 3, 5 and 10 years after LT, respectively. The patients were all male. The types of de novo tumors included digestive system tumor (8 in 14), lung cancer (2 in 14), urologic neoplasm (2 in 14), and hematologic malignant tumor (2 in 14). Over a mean follow-up of 24 months after diagnosis of de novo malignancy, 7 patients (50.0%) died; the overall 5-year patient survival rate was 54.5%. The relative risk of malignancy following LT was 9.5 folds higher than the general Chinese population. CONCLUSION: The relative risk of malignancy following LT was much higher than the general Chinese population. Digestive system tumor is the most common type of de novo malignancy after LT in China.

OBJECTIVE:To observe the clinical efficacy and safety of Buzhong yiqi wuling decoction combined with western medicine in the treatment of chronic congestive heart failure(CHF). METHODS:120 CHF patients were divided into observation group and control group by random number table method,with 60 cases in each group. Control group received conventional western medicine treatment as rest,low salt diet and diuretics. Observation group was additionally given Buzhong yiqi wuling decoction,one dose a day,at twice,on the basis of control group. Treatment course of 2 groups lasted for 2 weeks. Average TCM symptom score, level of plasma NT-proBNP,6 min walk test(6MWT)distance before and after treatment,clinical efficacy and the occurrence of ADR were compared between 2 groups. RESULTS:Before treatment,there was no statistical significance in average TCM symptom score,level of plasma NT-proBNP and 6MWT distance between 2 groups(P>0.05). After treatment,average TCM symptom score and level of plasma NT-proBNP of 2 groups were decreased significantly,and the observation group was more significant than the control group,with statistical significance(P<0.05);6MWT distance of 2 groups were improved significantly compared to before treatment,and the observation group was significantly longer than the control group,with statistical significance(P<0.05). After treatment,total effective rate of observation group(93.33%)was significantly higher than that of control group(83.33%),with sta-tistical significance(P<0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:Buzhong yiqi wuling decoction is an ef-fective prescription to treat CHF,and can relieve clinical symptoms,improve the cardiac function,decrease NT-proBNP level and en-hance the patient exercise tolerance with good safety.
