BACKGROUND: There are various reports on studies of tear secretion and tear film function in patients with diabetes mellitus over the past. In recent years, tear proteins have drawn more and more attentions on evaluation of tear film function.OBJECTIVE: To observe the contents of main tear proteins and basal tear secretion of patients with type 2 diabetes mellitus and normal persons so as to probe into tear secretion and tear film function of patients with diabetes mellitus.DESIGN: Case-control observation was designed.SETTING: Department of Ophthalmology, Southwest Hospital, Third Military Medical University of Chinese PLA.PARTICIPANTS: Totally 50 cases (100 eyes) of type 2 diabetes mellitus were employed, which were diagnosed in Department of Ophthalmology and Department of Endocrinology, Southwest Hospital of Third Military Medical University of Chinese PLA from December 2001 to December 2002. They were free from ocular surgical and laser treatment, local medication in recent period and contact lens. Of those, there were 25 cases (50 eyes) in proliferating diabetic retinopathy group and 25 cases (50 eyes) in nonproliferating diabetic retinopathy group. In addition, 25 cases (50 eyes) of normal persons with matched age and sex were taken as the control group.There was no significant difference in age and sex among 3 groups (x2=0.024,0.321 ;P ＞ 0.05). All of the participants were in the know before the experiment.METHODS: [1] Tear collection: 10 cases (20 eyes) were randomized from two diabetic groups and the control successively. Capillary pipette method was used to collect non-irritative tear 10 μL from lower lacrimal punctum that was preserved in refrigerator at -20 ℃ (＜ 1 month). [2] Determination of total tear protein amount: Lorry method was used to determine the concentration of total tear protein, in which, calf serum albumin was taken as the criteria. [3] Determination of contents of main tear proteins: SDS-PAGE (sod.dodecyl sulfate-polyacrylamide gel electrophoresis) was used and Coomassie brilliant blue staining and Bio-Rad imaging analyzing system were applied for the analysis of isolated protein strips in quality and quantity. [4] Determination of rupture time of tear film: glass rod was used to get 20 g/L fluorescein sodium and drop in conjunctival sac. The examined person was required to blink gently for several times and open the eyes naturally and stare forward. That the first ruptured "black hole" was discovered on the complete tear film was taken as the rupture time of tear film. [5] Experiment of basal tear secretion: No.41 Whatmann filtering paper was used, folded in 5 mm, and placed at 1/3 of conjunctiva in the lower eyelid. Five minutes later, the paper was removed and length of it after wetting was measured. [6]Experiment with rose Bengal staining: glass rod was used to get 10 g/L rose Bengal and drop in conjunctival sac. After eyes blinking for several minutes, the observation was performed with green light filter under slit lamp (evaluation criteria: corneal conjunctiva of palpebral fissure stained+, stained to the inferior bulbar conjunctiva++,stained to the superior bulbar conjunctiva). Dry eye disease was diagnosed indirectly with red-stained epithelial cells and mucin.MAIN OUTCOME MEASURES: [1] Concentration of total tear protein. [2]Concentrations of various main tear proteins. [3] Rupture time of tear film. [4]Value of basal tear secretion. [5] Positive rate of rose Bengal staining.RESULTS: Totally 50 cases (100 eyes) in diabetes groups and 25 cases(50 eyes) in the control group all entered result analysis. [1] Concentration of total tear protein: there was no significant difference among 3 groups (P＞ 0.05). [2] Concentrations of various main tear proteins: the results of lysozyme, lactoferritin and tear specific prealbumin in proliferating diabetic retinopathy group were lower remarkably compared with the control[ (0.94±0.21)vs ( 1.33±0.31 )g/L , ( 1.10±0.24)vs ( 1.67±0.43 )g/L, (0.98±0.22) vs (1.49±0.32)g/L, P ＜ 0.01]. Compared with non-proliferating diabetic retinopathy group, the results of lactoferritin and tear specific prealbumin were lower (P ＜ 0.05). There was no significant difference in human serum albumin among 3 groups (P ＞ 0.05). [3] Rupture time of tear film:compared with non-proliferating diabetic retinopathy group and the control, the rupture time of tear film in proliferating diabetic retinopathy group was reduced significantly [(7.68±2.21)s vs (9.92±2.37)s and(10.80±2.23)s,(P ＜ 0.01 )]. [4] Value of basal tear secretion: the value in proliferating diabetic retinopathy group was less significantly than that in non-proliferating diabetic retinopathy group and the control [ (8.00±2.10)vs( 11.02± 1.97 )mm and ( 12.17±2.08 )mm, P ＜ 0.05]. [5] Positive rate of rose Bengal staining: the positive rate in proliferating.diabetic retinopathy group was higher significantly than non-proliferating diabetic retinopathy group and the control (48% vs 24% and 14%, P ＜ 0.05, P ＜ 0.01).CONCLUSION: It is suggested in the results of this paper that abnormal tear secretion and tear film function are apt to present in patients with type 2 diabetes mellitus and the declined tear film function is more remarkably in the patients with proliferating diabetic retinopathy specially. SDS-PAGE benefits the discovery of changes in tear proteins in diabetic patients.

ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

Objective In order to analyze the variation of HA genes of influenza viruses (H1N1) by being compared with the vaccine strain A/California/07/2009(H1N1) recommended by WHO ,influenza viruses (H1N1) isolated from 2009 to 2014 were selected to do this study .Methods According to the different isolating time and place ,47 strains of H1N1 collected from 2011 to 2014 were selected .Then the 47 strains′ nucleotide sequence of HA genes which were sequenced in the study and other 25 se‐quences of HA genes which were sequenced in 2009 were collected .Nucleotide and amino acid sequences were analyzed by using molecular biology software ,and the phylogenetic trees were drawn .Results A total of 72 strains isolated from 2009 to 2014 were closely related to the vaccine strain A/California/07/2009(H1N1) ,the nucleotide variance and amino acid variance between the 72 strains were 0-2 .7% and 0-3 .1% respectively .Compared with the vaccine strain A/California/07/2009(H1N1) ,the nucleotide variance and amino acid sequence variance were 0 .4% -2 .4% and 0 .9% -3 .1% respectively .The amino acids sequence indicated that ,although the variance was increased by years ,the H1N1 viruses were still showed characteristics of low pathogenic influenza viruses .It was also found that there were 9 strains lost their potential glycosylation site at HA protein site 481 in 2009 ,while in 2013 there were 6 strains got new potential glycosylation sites at HA protein site 162 .Conclusion The vaccines (H1N1) recom‐mended by WHO was still protective to people in Chongqing .But as time goes by ,antigen drift may occur in some new antigenic drift strains and the routine monitoring of influenza viruses should be continued .

A HPLC method of analysis of Monascus citrinin was established. More than 30 strains of Monascus spp. were cultured in steamed rice at solid state or in MSG liquid medium composed of monosodium glutamate as sole nitrogen source and glucose as sole carbon to investigate their ability of producing citrinin. The results indicated that most of the Monascus strains are able to produce citrinin. MSG medium can be used as a specific culture medium to qualitatively identify if the strain is the potential citrinin producer. But to confirm whether the Monascus strains are potential citrinin producers, these strains should be cultured in several cultivation methods, as the culture states and culture conditions influence the citrinin production greatly.
