AIM:To study the changes of tear film and ocular surface after the coaxial micro incision 2. 2mm and 2. 8mm in the phacoemulsification.
METHODS:Eighty-six patients ( One hundred and six eyes ) from 2014/06 to 2016/01 in our hospital were enrolled. The patients were randomly divided into two groups. Forty-four patients ( Fifty-three eyes) in group A: coaxial 2. 2mm micro- incision phacoemulsification cataract extraction and intraocular lens(IOL) implantation;Forty-two patients ( Fifty-three eyes ) in group B: the conventional coaxial 2. 8mm small incision phacoemulsification cataract extraction and IOL implantation. The break up time ( BUT) , dry eye symptom ( DES) score, Schirmer's I test ( SⅠt ) and lid-wiper epitheliopathy ( LWE ) score were assessed preoperatively and postoperatively.
RESULTS:At 1wk, 1 and 2mo postoperatively, the BUT in two groups decreased after operations, and the BUT of group B was significantly lower than those of group A, the differences were statistically significant ( t = 3. 098, 4.512, 4.329; all P < 0. 05 ). The DES score in two groups increased, the DES score of group B was significantly higher than those of group A and the differences were statistically significant (t=-9. 449, -10. 029, -7. 141; all P<0. 05). The SⅠt in two groups increased after operations, the SⅠt of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 293, -4. 009, -3. 283; all P<0. 05). The LWE score in two groups increased after operations, the LWE score of group B was significantly higher than those of group A and the differences were statistically significant (t=-6. 542,-5. 125, -3. 632; all P<0. 05). At 6mo postoperatively, compared with the preoperative data, the BUT, DES score, S Ⅰ t and LWE score in group A showed no statistically significant differences (t=0. 659, 1. 276, 0. 548, 0.169; P>0. 05). The BUT, DES score, SⅠt and LWE score in group B showed statistically significant differences (t=-4. 063, 7. 306, 3. 621, 4. 208;all P<0. 05).CONCLUSION:Ocular surface has less damage and tear film has little influence at early stage after the coaxial 2.2mm microincision phacoemulsification, compared with the conventional coaxial 2. 8mm incision phacoemulsification surgery.

In order to evaluate the characteristics of the spray drying of total flavonoids of Epimedium extracts assisted with soybean polysaccharide, a certain percentage of soybean polysaccharide or polyvidone were added to the total flavonoids of Epimedium extract to conduct the spray drying. The effect of soybean polysaccharides against the wall sticking effect of the spray drying was detected, as well as the powder property of total flavonoids of Epimedium spray drying powder and the dissolution in vitro behavior of the effective component. Compared with the total flavonoids of Epimedium spray drying powder, soybean polysaccharide revealed a significant anti-wall sticking effect. The spray drying power which had no notable change in the grain size made a increase in the fluidity, improvement in the moisture absorption and remarkable rise in the dissolution in vitro behavior. It was worth further studying the application of soybean polysaccharide in spray drying power of traditional Chinese medicine.

Objective To investigate the effcts of cervical mild hypothermia auxiliary therapy on stress reaction in patients with cervical spinal cord injury. Methods 84 cases cervical spinal cord injury patients were randomly divided into two groups:a cervical mild hypothermia group (42 cases)and a routine treatment group (42 cases), 64 healthy men who come for health examination were recruited and served as healthy control. Routine treatment were used in both treatment groups, in edition, the LM-HAT was just applied in mild hypothermia group. The changes of the concentrations of corticotropin releasing hormone (CRH), adrenocorticotropin hormone (ACTH), corticosteroid (Cor), arginine vasopessin (AVP) in serum and the symptoms of the stress dsease(hypertension, high blood sugar)were observed before treatment and 1 week after treatment. Results The concentrations of CRH, ACTH, Cor, AVP in serum and the symptoms of stress disease in mild hypothermia group and routine treatment group were improved significantly at week after treatment(P<0.05), but the therapeutic effects of mild hypothermia group were better than that of routine treatment group (P<0.05). Conclusions The cervical mild hypothermia auxiliary therapy could significantly inhibit the secretion of stress hormones, make the H-P-A axis stable and promote the stress disease recovery.

Objective To understand the genetic polymorphism of Salmonella and Staphylococcus aureus in Guangdong province, as well as to explore methods for identifying and tracing the source of these two foodbome pathogens. Methods Using the automated ribotyping system, two foodbome pathogens were tested with either EcoR Ⅰ or Pvu Ⅱ restriction enzymes. BioNumerics software was then applied for image analysis, database establishment and other corresponding analysis. Results Digestion of 32 Salmonella isolates with Pvu Ⅱ yielded 19 different ribotypes,and digestion of 14 Salmonella isolates with EcoR Ⅰ yielded 2 different ribotypes. Staphyloccus aureus isolates showed greater genetic diversity, whereas EcoR Ⅰ digestion of 49 different isolates yielded 31 different ribotypes. Conclusion Unique Salmonella and Staphylococcus aureus isolates could be identified through ribotyping. Although Salmonella serotyping and ribotyping were not strongly correlated, the combination of both restriction enzymes could be used to more effectively identify the genetic relationship among different strains as well as the source of food poisoning. Thus, not only could the genetic relationships amongst the different strains be inferred through ribotyping skills, the source of food poisoning and mode of transmission could also be determined under the use of this method.

OBJECTIVETo survey the incidence of acute febrile reaction in elderly patients receiving intravenous zoledronic acid for osteoporosis and identify the related factors.

METHODSThirty-eight elderly patients with osteoporosis were hospitalized and treated with intravenous infusion of 5 mg zoledronic acid in 2010. The incidence of acute fever reaction was observed in these patients , and the time of fever onset, duration, average maximum temperature, and antipyretic drug used were recorded. The patients with and without acute febrile reaction were compared for age, duration of osteoporosis, sex ratio, use of parathyroid hormone before zoledronic acid treatment, β-fragment of collagen breakdown, calcitonin, osteocalcin, serum calcium, and use of anti-osteoporosis drugs before the treatment.

RESULTSAcute fever reaction occurred in 12 (31.6%) of the patients. Two of the patients had fever on the day of zoledronic acid treatment, and the other patients developed fever after the first day of treatment, with a mean duration of 1 day and a maximum temperature of (38.5∓0.84) degrees celsius;. The fever was treated with a mean of 3.55∓1.21 pseudoephedrine tablets. The patients with fever showed significantly higher parathyroid hormone levels before treatment than those without fever (P<0.05); osteocalcin, calcitonin, β-fragment of collagen breakdown, or serum calcium showed no significant difference between the two groups.

CONCLUSIONAcute febrile reaction, often moderate and transient, is common in elderly patients receiving intravenous zoledronic acid for osteoporosis, and its occurrence is possibly associated with parathyroid hormone levels before the treatment.

The aim of this study was to investigate the effect of evodiamine on the proliferation and the immune function of thymocytes and splenocyte of mice from three germlines, which were 8 weeks old masculinity BALB/c, C57BL/6 and F1 hybridization mice. Cells of thymus and spleen were harvested and prepared as unicellular suspension. Cell proliferation was detected by MTT method, while the concentration of IL-2 was detected by ELISA, mRNA levels of bcl-2 and cdk2 in cells treated with evodiamine were detected by RT-PCR, the apoptosis rate and intracellular reactive oxygen species (ROS) concentration were analyzed by FCM, and the protein levels of BCL-2, CDK2 and BAX were determined by fluorescence microscope. The results indicated that at 0.5, 0.75 and 1 micromol/L, evodiamine inhibited the proliferation and externalization of thymocytes and splenocytes stimulated with ConA (p < 0.05). At 0.75 micromol/L, evodiamine inhibited the secretion of IL-2, decreased the mRNA level of bcl-2 and cdk2, and induced apoptosis of thymocytes and splenocytes (p < 0.05). Intracellular ROS concentration increased significantly after treatment with evodiamine for 12 hours (p < 0.05). The death rate increased at a prolong period of time. After treatment with evodiamine for 24 and 48 hours, the cells were divided into two groups, one of which was negatively stained by 2 7-dichlorofluorescein (DCF), which indicated that ROS level decreased significantly in the dying cells. It is concluded that evodiamine inhibits proliferation and induces apoptosis of thymocytes and splenocytes from different germline mice, and at the same time decreases secretion of IL-2 through down-regulating bcl-2 and cdk2 levels.

BACKGROUNDThe molecular mechanisms underlying the endometriosis are still not completely understood. In order to test the hypothesis that the approaches in phosphoproteomics might contribute to the identification of key biomarkers to assess disease pathogenesis and drug targets, we carried out a phosphoproteomics analysis of human endometrium.

METHODSA large-scale differential phosphoproteome analysis, using peptide enrichment of titanium dioxide purify and sequential elution from immobilized metal affinity chromatography with linear trap quadrupole-tandem mass spectrometry, was performed in endometrium tissues from 8 women with or without endometriosis.

RESULTSThe phosphorylation profiling of endometrium from endometriosis patients had been obtained, and found that identified 516 proteins were modified at phosphorylation level during endometriosis. Gene ontology annotation analysis showed that these proteins were enriched in cellular processes of binding and catalytic activity. Further pathway analysis showed that ribosome pathway and focal adhesion pathway were the top two pathways, which might be deregulated during the development of endometriosis.

CONCLUSIONSThat large-scale phosphoproteome quantification has been successfully identified in endometrium tissues of women with or without endometriosis will provide new insights to understand the molecular mechanisms of the development of endometriosis.

In this study, daphnetin and its major metabolites in the intestinal wall of rats were identified by liquid chromatography and quatrupole-time of flight mass spectrometry. Perfusion fluid of duodenum, jejunum, ileum and colon were collected separately for 2 hours from the rat intestine following perfusion with daphnetin. The metabolites of daphnetin in the perfusion fluid of different intestine segments were analyzed by the liquid chromatography and quatrupole-time of flight mass spectrometry. It is shown that the parent drug daphnetin and four metabolites were found in the perfusion fluid of duodenum, jejunum and ileum. However, no metabolites were found in the colon. Among the four metabolites, two daphnetin sulfates (m/z 257) were first discovered as the phase II metabolites of daphnetin in rats, which revealed a new way of daphnetin metabolism in rats.
