OBJECTIVETo observe the effect of low molecular weight heparin calcium (LMWHC) combined Compound Danshen Injection (DI) on nephrotic syndrome patients with early onset severe preeclampsia.
METHODSTotally 80 nephrotic syndrome patients with early onset severe pre-eclampsia were randomly assigned to four groups voluntarily, i.e., Group A (22 cases, treated by magnesium sulfate), B (19 cases, treated by magnesium sulfate plus LMWHC), C (21 cases, magnesium sulfate plus DI), D (18 cases, magnesium sulfate plus LMWHC and DI). Umbilical arterial S/D ratios, amniotic fluid index (AFI), prolonged gestational age, placenta weight, neonatal weight, and Apgar score were compared among the four groups.
RESULTSCompared with before treatment in the same group, umbilical arterial S/D ratios decreased in the four groups (P <0. 05). AFI decreased in Group A, while it increased in Group B, C, and D (P<0. 05). Compared with Group A at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group B, C, and D (P <0. 01 , P <0. 05). Prolonged gestational age and neonatal weight were increased in Group B, C, and D (P <0. 01, P <0. 05). Placenta weight were increased in Group B and D (P <0. 05). Apgar scores at 1 and 5 min were improved in Group D (P <0. 05). Compared with Group B and C at the same time point, umbilical arterial S/D ratios decreased, and AFI increased in Group D (P<0. 05). Compared with Group B, prolonged gestational age and placenta weight were decreased in Group C, but prolonged gestational age and placenta weight were increased in Group D (P <0.05). Compared with Group C, prolonged gestational age, placenta weight, and neonatal weight were increased in Group D (P <0. 05).
CONCLUSIONTreatment of nephrotic syndrome patients with early onset severe pre-eclampsia by LMWHC combined DI could prolong gestational ages, obviously improve prenatal outcomes, with better effect obtained than using any of them alone.

OBJECTIVETo analyze the clinical effectiveness of Compound Danshen Injection (CDI) in treating patients with early onset severe preeclampsia.
METHODSOne hundred and twenty patients with early onset severe preeclampsia were recruited and their gestational age ranged between 26 and 34 weeks. Sixty patients who volunteered to receive CDI were recruited as the treatment group, while 60 inpatients were recruited as the control group at the same time period. The routine therapy was given to those in the control group. CDI was intravenously dripped to those in the treatment group additionally by adding in 250 mL 5% glucose injection, once daily. The treatment for all lasted for 7 successive days. The D-dimer (DD), fibrinogen (Fg), hematocrit (HCT), tissue plasminogen activator (t-PA), plasminogen activator inhibitor-1 (PAI-1), mean arterial pressure (MAP), 24 h urine volume (UV), 24 h urine protein (24 hUP), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein A (apoA1), apolipoprotein B (apoB), umbilical arterial S/D ratio (S/D), and amniotic fluid index (AFI) were compared between the two groups before and after treatment. The placenta weight (PW), neonatal weight (NW), 1 min Apgar scoring were compared between the two groups before and after treatment.
RESULTSThere was no difference in DD, Fg, HCT, t-PA, PAI-1, MAP, UV, 24 hUP, TC, TG, HDL-C, LDL-C, apoA1, apoB, S/D, or AFI between the two groups before treatment (P>0.05). In the treatment group PAI-1, Fg, and 24 hUP decreased more after treatment, and they were lower than those of the control group after treatment. The UV and AFI increased and they were higher than those of the control group after treatment with statistical difference shown (P<0.05, P<0.01). In the control group the UV increased and 24 hUP decreased after treatment (P<0.01). There was no improvement in the rest indices (P>0.05). The PW, NW,and 1 min Apgar score > or = 7 were all higher in the treatment group than in the control group, showing statistical difference (P<0.05).
CONCLUSIONCDI was helpful to improve the high condensation state of patients with early onset severe preeclampsia, protect important organs of the mother, and improve the prognosis of neonates.

International Eye Science 2017;17(2):348-350
AIM: To further investigate the etiology and treatment strategies of diabetic macular edema(DME)by studying the correlation between responses to intravitreal injection of Ranibizumab(IVR)and diabetic retinopathy(DR)extent in DME patients.
METHODS: This study comprised 33 eyes of 27 non proliferative diabetic retinopathy(NPDR)patients with DME and 34 eyes of 32 PDR patients with DME, who had been followed for at least 6mo after IVR. We compared the responses to the anti-VEGF treatment between the two groups.
RESULTS: NPDR patients had strong statistical improvement in best corrected visual acuity(BCVA)and central macular thickness(CMT)after both 3-month treatment and 6-month treatment(P<0.05), While PDR patients had not(P>0.05). There were also statistical differences(P<0.05)in BCVA and CMT between NPDR group and PDR at a time when the patients had received both 3-month treatment and 6-month treatment.
CONCLUSION: Different extents of DR have influence on DME responses to anti-VEGF.

OBJECTIVETo study the curative effects of pirfenidone (PF) on pulmonary fibrosis induced by paraquat (PQ) in mice and to provide the theoretical basis for clinical treatment.
METHODSNinety adult healthy male ICR mice were randomly divided into six groups: control group, PQ group, 2 mg/kg Dexamethasone group, 25 mg/kg PF group, 50 mg/kg PF group and 100 mg/kg PF group, there were 15 mice in each group. The corresponding volume of normal saline was given to the each mouse in control group according to the weight, after 2 h 0.1% CMC was given to the each mouse of control group one time by intragastric administration, then the CMC was administrated at regular time until sacrifice. All mice for other 5 groups were exposed to 100 mg/kg PQ by intragastric administration. At 2 h after exposure to PQ, 0.02 ml/10 g dexamethasone and 25, 50, 100 mg/kg PF were given to mice for dexamethasone group and for 3 PF groups by intragastric administration each day for 49 days, respectively. The lung coefficient was calculated and pathological changes of lung tissue were observed by HE staining for each mouse. The hydroxyproline (HYP) level in lung tissue was measured for each mouse. The mRNA level of and the protein level of TGF-β(1) in lung tissue for each mouse were determined, and the protein level of TGF-β(1) in the bronchus-alveolus lavage fluid (BALF) of each mouse was detected.
RESULTSThe survival rates on the 3rd day in PQ group, 3 PF groups and dexamethasone group were 53.33%, 46.67%, 73.33%, 86.67% and 80%, respectively. The survival rates on the 3rd day in dexamethasone group, 50 mg/kg and 100 mg/kg PF groups were significantly higher than those of PQ group and 25 mg/kg PF group (P < 0.05). The lung coefficients of 3 PF groups were significantly lower than that of the PQ group (P < 0.05). The lung tissue HYP levels of dexamethasone group and 3 PF groups were 50.95 ± 11.65, 44.52 ± 9.48, 43.27 ± 6.01 and 40.82 ± 5.90 mg/g respectively, which were significantly lower than that (74.27 ± 3.68) of PQ group (P < 0.01). The TGF-β(1) protein levels of BALF in dexamethasone group, 50 and 100 mg/kg PF groups were 22.03 ± 7.27, 27.75 ± 5.84 and 21.31 ± 6.82 ng/ml respectively, which were significantly lower than that (52.52 ± 15.51) ng/ml of PQ group (P < 0.01) The expression level of TGF-β(1) mRNA in 100 mg/kg PF group decreased significantly, as compared with PQ group (P < 0.01).
CONCLUSIONPF could reduce the collagen deposition and pulmonary fibrosis induced by PQ in mice lungs.

OBJECTIVETo investigate the effect of iron on the growth, physiology and photosynthesis of cyanobacteria.
METHODSA gradient of iron concentrations was employed to investigate the growth, photo-pigments (chlorophyll A and phycocyanin), and cell chemical contents (C, N, P) of Microcystis aeruginosa in response to different iron additions.
RESULTSThe specific growth rate during the exponential growth phase, as well as the cell chlorophyll A and the phycocyanin content, was limited by iron below 12.3 tmol Fe x L(-1). The growth was inhibited when the iron concentration was at 24.6 micromol Fe x L(-1). The cell chlorophyll A and the phycocyanin content were saturated when the iron concentration was above 12.3 micromol Fe x L(-1) and declined slightly at 24.6 micromol Fe x L(-1). At a low iron concentration (about 6.15 micromol Fe x L(-1) and less), the cell nitrogen and carbohydrate content were iron limited, and the variation of the cell phosphorus content was similar to that of the nitrogen and carbohydrate, with a transition point of 12.3 micromol Fe x L(-1).
CONCLUSIONThe variation of cynobacteria growth is synchronous with that of the photo-pigments or the cell chemical content, and there exist relationships among photosynthesis, growth and internal chemical content, which could be useful for the growth estimation from the cell characteristics.

OBJECTIVETo explore the exposure level and risk factors of heavy metal among Shanghai infants in their prenatal period.
METHODSA total of 1652 pregnant or puerperal women were recruited from 10 midwifery-qualified hospitals in Shanghai since October 2008 to October 2009, by the stratified cluster sampling method. They answered the questionnaire and their umbilical cord blood and serum were collected to detect the content of Pb, Hg, Mn, Cd, As and Tl. The risk factors were analyzed by single and multiple regression methods respectively.
RESULTSThe median value of the content of Pb, Hg, Mn, Cd, As and Tl were 41.00, 1.88, 4.10, 0.03, 0.86 and 0.02 µg/L respectively. The Hg concentration of pregnant women who ate fish for 4 - 7 times per week (9.7% (160/1652)) was 2.76 µg/L, which was higher than that of pregnant women who only ate fish for 1-3 times per week (49.3% (814/1652)) and those who seldom ate fish (40.0% (661/1652)); the Hg concentration in the two groups above were 2.41 and 2.03 µg/L separately. The difference had statistical significance (χ(2) = 36.40, P < 0.001). Meanwhile, the concentrations of Pb and Tl in the group of pregnant women whose houses were remodeled by PVC pipe (85.0% (1404/1652)) was higher than the concentrations in group of pregnant women whose houses were remodeled by galvanized pipe (15.0% (248/1652)); the Pb concentration in the two groups above were 45.54 and 40.00 µg/L (Z = 2.54, P < 0.05) and the Tl concentration in the two groups above were 0.021 and 0.018 µg/L (Z = 2.97, P < 0.05). However, the As concentration in the group of PVC pipe remodeled was 4.33 µg/L, which was lower than that in the group of galvanized pipe (9.37 µg/L). The difference had statistical significance (Z = 3.99, P < 0.01). The concentrations of Mn, Cd and Tl in the groups of pregnant women whose house had been remodeled in the last 3 years (38.0% (628/1652)) were 14.78, 0.51 and 0.022 µg/L separately, which were all significantly higher than those in the groups of women whose houses' were not remodeled (62.0% (1024/1652)), whose concentrations were 11.01, 0.29 and 0.02 µg/L respectively. The differences had statistical significance (Mn: Z = 2.46, P < 0.05; Cd: Z = 2.38, P < 0.05; Tl: Z = 2.81, P < 0.01).
CONCLUSIONThe infants in Shanghai were exposed to heavy metals in their prenatal period. The main sources of the exposure were daily diet and remodeled pollution.

OBJECTIVEThe purpose of this study was to analyze the electrocardiographic features of the people living in the area with high incidence of unexplained sudden deaths in Yunnan province.
METHODThe electrocardiograms of 338 residents from three villages (Dayao, Ninglang, Heqing) with high incidence of unexplained sudden deaths and one control village (Dali) were analyzed [averaged age was (33.4 +/- 11.7) years, 175 men and 163 women].
RESULTSThe incidence of cardiac arrhythmias was similar low in all groups. The left ventricular hypertrophy was observed in 34.6% of residents from Dayao. QTc significantly prolonged in the residents from all 3 high incidence areas compare the control area of Dali [control (386.8 +/- 27.22) ms, Ninglang (428.92 +/- 25.71) ms, Heqing (440.67 +/- 28.03) ms, Dayao (417.7 +/- 24.00) ms, P < 0.05 vs. control]. Incidence of U wave was significantly higher in Heqing village than that in control village (P < 0.05). The QUc of these 3 villages was: (613.67 +/- 37.34) ms, (597.19 +/- 46.47) ms, (608.59 +/- 39.59) ms respectively, and also significantly longer than the control village of Dali (589.33 +/- 41.27) ms (P < 0.05). The typical pattern of U wave presents as enlarged U wave and apparent T-U complex. In the 7 residents who have the family history of unexplained sudden death, 6 residents have U wave, and 4 of them present typical U wave pattern.
CONCLUSIONThe significant ECG changes in villages with high incidence of unexplained sudden death in Yunnan province were prolonged QTc, enlarged U wave and apparent T-U complex and these ECG features suggested the repolarization abnormalities of the heart in these subjects.

OBJECTIVETo investigate the clinical features of unexpected sudden death (SUD) clustered in families in Yunnan province.
METHODSThis retrospective study analyzed the clinical features of SUD occurred between July to September 2005 in 7 families in Yunnan province.
RESULTSAll 16 SUD patients shared common clinical features such as fatigue and repeated syncope and one group of SUD patients (n = 8 from 4 families) presented with the gastric intestinal tract manifestations including nausea, vomiting, abdominal pain and diarrhea with suspected dietary history and abnormal laboratory enzyme findings (GOT/GPT, CK/CKMB, LDH/LDH1 etc.). In SUD patients without gastric intestinal tract manifestations (n = 8 from 3 families), there were no clear symptoms before death and repeated ventricular tachycardia and ventricular fibrillation were recorded in one survivor. There was no clear evidence for the involvements of hereditary and infectious factors for observed SUD.
CONCLUSIONThe reason for the unexpected sudden death clustered in 7 families in Yunnan remains unclear. Repeated syncope and fatigue served as the common clinical features in the presence or absence of gastric intestinal tract manifestations in all SUD cases. Further studies are needed to clarify the pathology and detailed clinical manifestations of SUD occurred in this area.

OBJECTIVETo study the effects on the expression of mGluR5 mRNA and protein levels in primarily cultured hippocampal neurons after lead exposure.
METHODSPrimary embryonic rat hippocampal neuronal culture was prepared. On the 3(rd) day of incubation, lead chloride solution was added into medium to produce four different lead exposure levels: 0, 1 x 10(-8) mol/L, 1 x 10(-6) mol/L, 1 x 10(-4) mol/L Pb(2+). After 10 days of incubation, the neurons were collected to measure the alteration of mGluR5 mRNA expression by real-time fluorescent quantity PCR and the expression of mGluR5 in protein level by Western blot.
RESULTSThe studies revealed that mGluR5 mRNA expression was down-regulated after lead exposure in a dose-dependent manner. The mGluR5 mRNA expression of the lower lead-exposed neurons (Pb(2+) 10(-8) mol/L), the medium lead-exposed neurons(Pb(2+) 10(-6) mol/L), the higher lead-exposed neurons(Pb(2+) 10(-4) mol/L) were 0.724, 0.421, 0.321 times less than that of the controls, respectively. The Western blot demonstrated that mGluR5 expression in protein level should be decreased after lead exposure.
CONCLUSIONThe expression of mGluR5 in mRNA and protein levels should be down-regulated after lead exposure at different lead levels in a dose-dependent manner.
