Objective To patients with neonatal dacryocystitis underwent left Ofloxacin Gel, Tobramycin and Dexamethasone Ophthalmic Ointment and lacrimal surgery combined with treatment effects were observed.MethodsIn Ningxia Hui Autonomous Region Qingtongxia City People's Hospital during December 2015 to December 2016 for dacryocystitis in 130 cases according to the data analysis, using different treatment schemes were divided into two groups, 65 cases underwent lacrimal surgery as control group, 65 cases and left Ofloxacin Gel, Tobramycin and Dexamethasone Ophthalmic Ointment combined treatment as the observation group, blocking characters and comparison of complications two groups of clinical curative effect, lacrimal duct.ResultsIn the observation group, the total effective probability of 96.92% higher than the control group of 80.00%(P<0.05), and the nasal deformity, nasolacrimal duct, lacrimal bone deformity multiple adhesions or obstruction and lower incidence of membranous obstruction of lacrimal duct is lower than that of control group (P<0.05);the total complication rate in the observation group(3.08%) than the control group(21.54%)low (P<0.05).ConclusionNeonatal dacryocystitis underwent left Ofloxacin Gel, Tobramycin and Dexamethasone Ophthalmic Ointment and lacrimal surgery combined therapy can improve the clinical symptoms and characteristics of lacrimal duct obstruction, and reduce postoperative complications, which may be of clinical promotion and application.

The factors impacting the pregnancy rate and the live birth rate mainly include ovary function disorder and low endometrial receptivity, which can cause the difficulty in embryo implantation, early miscarriage and pregnancy failure. In recent years, researchers of the traditional Chinese medicine (TCM) have made active efforts in assisting IVF-ET, so as to achieve a great advance in improving the ovary reaction, treating the ovarian hyperstimulation syndrome (OHSS), improving the follicle, embryo quality and endometrial receptivity and protecting the fetus, which had been summarized in this article.

Objective That decline of estradiol in serum of postmenopausal women can result in dry eye has been accepted at present. However, the change of estradiol in tear of postmenopausal women has been not reported ever. This study was to discuss the relationship between dry eye syndrome and estradiol in tears and serum of postmenopausal women. Methods Total 62 eyes of 62 women were collected in this trial. The aim of this trial was informed orally and the informed consent was obtained from all the subjects. The 32 right eyes were from menopausal women for more one year and 30 right eyes were from premenopause women. The dry eye was diagnosed based on the abnormalities of tear break-up time (BUT), Schirmer I test, corneal fluorescence and subjective symptom of patients. The periphery blood specimen was collected from all the subjects, and tear specimen was obtained and quantified using filter paper. Estradiol contents in tears and serum were determined by chemiluminescence method. The bulbar conjunctiva was obtained by impression cytology, and the microstructure of conjunctiva was observed under the scanning electron microscopy. Results In comparison to the premenopause group, the content of estradiol in tears and serum in menopause group was significantly reduced(73. 50 ±24.47 vs 17. 43 ± 10. 92) (U = -6. 396, P =0. 001). In the premenopause group, the estradiol content between tear and serum showed the positive correlation (r = 0. 838, P = 0. 001) . However, no statistical correlation was found in estradiol content between tears and serum in menopause group(r =0. 127, P = 0. 487). The maicrostructure changes were seen in the dry eyes of postmenopausal women, and decrease of goblet cell and loosen of intercellular junction were found under the electron microscope. Conclusion The content of estradiol in tears in menopause group is significantly lower than that in the premenopause group. Estradiol content in tears and serum of the postmenopausal women showes insignificant correlation. This result indicates that the topical substitute therapy with estradiol is possible in dry eye.

Objective: To study the chemical constituents of Gynostema pentaphyllum. Methods: The chemical constituents were isolated and purified by silica gel, polyamide, and Sephadex LH-20 chromatography. Their structures were elucidated by physicochemical properties and spectral analysis. Results: Seventeen compounds were isolated and identified as dodecanoic acid (1), β-sitosterol (2), 3, 3', 5-trihydroxy-4', 7-dimethoxyflavanone (3), 1-2-benzenediol (4), 3'-O-methyltaxifolin (5), quercetin (6), rhamnetin (7), α-spinasterol-3-O-β-D-glucopyranoside (8), 3, 4-dihydroxy benzoic acid (9), narcissoside (10), L-rhamnosemono-hydrate (11), malonic acid (12), β-ethoxy-rutinoside (13), rutin (14), ombuoside (15), ginsenoside Rb1 (16), and β-daucosterol (17). Conclusion: Compound 1, 3-5, 7, 9, 10, and 12 are obtained from G. pentaphyllum for the first time.

Purpose　The aim is to modify the pyrogenic pathol ogy mo del induced by injection of saccharomycetet water in rats,and to eliminate the t emperature decline period after injection of saccharomycete water sc.Metho ds　It was measured that the anus temperature of both two groups of rats (one group was injected of incubated saccharomycete water and the other inj ected unincubated saccharomycete water sc) 1,2,3,4,6,8 h after injection respect ively.Results　The anus temperature had no decline period and the temperature rose quickly in the group of injected with incubated saccharomyc ete water (in 34℃thermostasis water).There was significant difference(P＜0.05 or P＜0.01)between incubated group and unincubated group in temperature risin g by t-test.Conclusion　No temperature declining peri od was observed in the pyrogenic pathology model of rat, if those rats were trea ted with saccharomycete water which was incubated at 34℃for 0.5 h.

Objective To analyze the application value of MSCT enhanced scanning in diagnosis of gastrointestinal mucoca associated lymphoid tissue(MALT) lymphoma.Methods 11 cases of gastrointestinal MALT lymphomas confirmed by pathology were analyzed retrospectively.The clinical data and imaging features of 11 cases were analyzed,including lesion sites, morphologic features and enhancement patterns of tumors,positions of lymph nodes,involvement of extranodal site excluding gastrointestinal tract.Results For morphologic features,8 cases (72.7%) were gastrointestinal wall thickening type, among them, 5 cases occurred in the stomach and 3 cases in the intestine;3 cases (27.3%) were localized mass/nodule type, among them, 2 cases occurred in the stomach and 1 case occurred in the intestine.The sign of aneurysmal dilatation was showed in 2 cases, which occurred in the intestinal tract.There was 1 case of localized mass/nodule MALT lymphoma in the ileocecal junction with local intestinal lumen stenosis.For the manifestations of enhanced scanning,10 cases (90.9%) of tumors were moderately or obviously enhanced, 9 cases (81.8%) showed homogeneous enhancement.For the involvement of lymph nodes and other extranodal organs, regional lymph nodes were involved in 5 cases(45.5%), regional lymph nodes and distant lymph nodes were involved in 1 case(9.1%), lymph nodes of both sides of the diaphragm were involved in 1 case (9.1%), extranodal sites excluding gastrointestinal tract were involved in 2 cases (18.2%).9 cases (81.8%) were classified as stage Ⅰ-Ⅱ, 2 cases (18.2%) were classified as stage Ⅳ.Conclusion MSCT enhanced scanning can provide a reliable basis for the diagnosis and staging of gastrointestinal MALT lymphoma.The chest and abdominopelvic cavity enhanced scanning is recommended as a routine examination.
