Objective To study curative efficacy of cyclophosphamide combined with VAD regimen in treatment of multiple myeloma and its effects on coagulation function.Methods 78 patients of multiple myeloma who received therapy from July 2013 to July 2016 in our hospital were selected as research objects, and divided into the control group and the observation group , the control group was treated with VAD regimen, while the observation group was treated with cyclophosphamide combined with VAD regimen.Then coagulation factor and anti-coagulation factor activity, adverse reaction, therapeutic effect after treatment between two groups were compared.Results After treatment, decreased blood coagulation factor, Protein C, protein S and antithrombin were increased between two groups , the difference was not statistically significant.Incidence of adverse reactions in observation group was less than the control group[15.38%(6/39)vs 46.15%(18/39)], the difference was statistically significant(P<0.05);The total effective rate of observation group was statistically higher than that in the control group [ 89.74%( 35/39 ) vs 58.97%( 23/39 ) ] , the difference was statistically significant(P<0.05).Conclusion Cyclophosphamide combined with VAD regimen is well for multiple myeloma, which can effectively improve the patient's condition, improve the life quality of patients, and will not cause a greater impact on blood coagulation function.

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.

Objective To explore the influence of type 2 diabetes mellitus combined with subclinical hypothyroidism on diabetic vascular complications.Methods One hundred and two patients with type 2 diabetes mellitus were selected.The serum free triiodothyronine (FT3),free thyroxine (FT4),thyroid stimulating hormone (TSH),anti-thyroid peroxidase antibody (TPO-Ab),thyroglobulin antibody (TG-Ab) levels were measured by chemiluminescence method.The patients were divided into type 2 diabctes mellitus combined with subclinical hypothyroidism group (47 cases) and type 2 diabetes mellitus with normal thyroid function group (55 cases) according to the thyroid function.The glycated hemoglobin (HbA1c),total cholesterol (TC),low-density lipoprotein cholesterol (LDL-C),triacylglycerol (TG),high-density lipoprotein cholesterol (HDL-C),urea nitrogen,creatinine and albumin levels were measured.The estimated glomerular filtration rate (eGFR) was calculated according to the formula of modification of diet in renal disease (MDRD).The presence of diabetic retinopathy was examined by fundus examination,and the presence of lower limb artery lesions was measured by vascular ultrasound.All indicators were compared between 2 groups.Results There were no statistical differences in age,disease course,HbA1c,body mass index (BMI),TC,TG,HDL-C,LDL-C,incidence of lower limb artery lesions and incidence of diabetic retinopathy between 2 groups (P＞ 0.05).TheeGRF in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significantly lower than that in type 2 diabetes mellitus with normal thyroid function group:(83.74 ± 21.55) ml/(min· 1.73 m2) vs.(115.02 ± 12.29) ml/(min· 1.73 m2),and there was statistical difference (t =4.274,P ＜ 0.01).The incidence of diabetic nephropathy in type 2 diabetes mellitus combined with subclinical hypothyroidism group was significanlty higher than that in type 2 diabetes mellitus with normal thyroid function group:48.9％ (23/47) vs.23.6％(13/55),and there was statistical difference (x2 =7.103,P＜ 0.01).Logistic regression analysis showed that subclinical hypothyroidism was a risk factor for diabetic nephropathy (OR =0.524,95％ CI 0.12-0.93,P ＜ 0.05),but it was not the risk factor for diabetic retinopathy (OR =0.618,95％ CI0.19-2.16,P =0.475) and lower limb artery lesions (OR =0.485,95％ CI 0.32-2.13,P =0.689).Conclusion Subclinical hypothyroidism in patients with type 2 diabetes mellitus has no obvious effect on lower limb arterial complications and diabetic retinopathy,but may increase the risk of diabetic nephropathy.

Thyroid emergency is a rare but potent ially life-threatening condition if not recognized early and managed properly. It is usually due to a severe exacerbation of a preexisting thyrotoxicosis, which later leads to decompensation in different organ systems. The treatment of thyroid emergency remains challenging even with the armamentarium of modern intensive care technologies, especially in patients with cardiac failure and major organ dysfunction.[1–3] Herein, the authors described a case of thyroid emergency with cardiac arrest (CA) supported by extracorporeal membrane oxygenation (ECMO).

Objective To study the effects of restructuring tissue inhibitor of matrix metatloproteinase-3 (rhTIMP-3) in combination with cisplatin (DDP) on the growth and apoptosis of A549 lung cancer cell line.Methods We made individual and combined use of different concentrations of rhTIMP-3 and DDP on A549 cells.Methyl thiazoyl terazolium (MTT) colorimetry was used to analyze cell growth inhibition,and flow cytometry technique was used to determine the cell cycle distribution and apoptosis rate.Results rhTIMP-3 and DDP both could inhibit the proliferation of A549 cells.rhTIMP-3 exerted its effect in the time-and concentration-dependent manners while DDP did so in the concentration-dependent manner;both induced the apoptosis of A549 cells.rhTIMP-3 could make the cells stay in S and G2/M phases,and DDP made the cells stay in S phase.The combination of them obviously strengthened the inhibition of A549 cell growth,and had obvious synergy in inducing apoptosis.Conclusion Both rhTIMP-3 and DDP can inhibit the proliferation of A549 cells and induce their apoptosis.The combined use of them not only can increase the inhibition of cell growth but also has synergy in inducing cell apoptosis.

OBJECTIVE:To compare the efficacy,safety,vascular endothelial growth factor(VEGF)and matrix metallopro-teinase-2 (MMP-2) of docetaxel combined with carboplatin and paclitaxel combined with cisplatin (DDP) in the treatment of ad-vanced ovarian cancer. METHODS:120 patients with advanced ovarian cancer were randomly divided into docetaxel combined with carboplatin group(60 cases)and paclitaxel combined with DDP group(60 cases). Docetaxel combined with carboplatin group received 70 mg/m2 Docetaxel injection,intravenous infusion of 1 h,d1;50 mg/m2 carboplatin injection,intravenous infusion of 1 h,d2. Paclitaxel combined with DDP group received 135 mg/m2 Paclitaxel injection,intravenous infusion of 24 h,d1;30 mg/m2 DDP for injection,intravenous infusion,d3;60 mg/m2 Paclitaxel injection (a maximum of 2.0 m2) by intraperitoneal infusion,d8. 3-week was regarded as 1 treatment course,and it lasted 6 courses. Clinical efficacy,VEGF,MMP-2,progression-free survival, overall survival before and after treatment,mortality rate within 2 years of treatment and the incidence of adverse reactions in 2 groups were compared. RESULTS:There were no significant differences in the objective response rate,disease control rate,mortal-ity rate,incidence of adverse reactions between 2 groups(P>0.05). The progression-free survival in docetaxel combined with car-boplatin group was significantly longer than paclitaxel combined with DDP group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in VEGF and MMP-2 level between 2 groups(P>0.05). After treat-ment,VEGF and MMP-2 level in 2 groups were significantly lower than before,and VEGF at different time points and MMP-2 level after 4 weeks,8 weeks and 12 weeks of treatment in docetaxel combined with carboplatin group were lower than paclitaxel combined with DDP group,the differences were statistically significant(P<0.05). CONCLUSIONS:Docetaxel combined with car-boplatin and paclitaxel combined with DDP shows similar efficacy and safety in the treatment of advanced ovarian cancer,but docetaxel carboplatin combined with is superior to paclitaxel combined with DDP in reducing VEGF and MMP-2 and improving pro-gression-free survival.

Objective To investigate the expression,clinicopathological significance and correlation of S100A4,EGFR and PI3K in lung adenocarcinoma.Methods Immunohistochemical method (EnVision two steps) was used to detect the expression of S100A4,EGFR and PI3K proteins in 84 lung adenocarcinoma tissue samples and 30 normal lung tissue samples.The relationship of S100A4,EGFR and PI3K expression with clinicopathologic factors,post-operative five-year survival and the correlations among the three proteins were analyzed.Results The positive expression rates of S100A4,EGFR and PI3Kin lung adenocarcinoma tissues were higher than those in normal tissues,respectively [(69.0 ％,58/84) vs (6.7 ％,2/30),(64.3 ％,54/84) vs (16.7 ％,5/30),(52.4 ％,44/84) vs (13.3 ％,4/30),P ＜ 0.01].The expression of S100A4,EGFR and PI3K proteins were positively correlated with the differentiated degree,lymph node metastasis,clinical stages,and five-year survival (P ＜ 0.05),but not correlated with other clinicopathologic factors (P ＞ 0.05).The expression of S100A4 was positively correlated with EGFR and PI3K in lung adenocarcinoma (P ＜ 0.01),and the expression of EGFR was positively correlated with PI3K (P＜ 0.01).Conclusions S100A4,EGFR and PI3K were closely related with the occurrence,development,metastasis and prognosis of lung adenocarcinoma.S100A4 might be an important marker in estimating biological behavior and metastasis tendence of lung adenocarcinoma.S100A4 may be correlated with EGFR and PI3K.
