ABSTRACT
Objective To understand the correlation and clinical significance between cystatin C and atherogenic index of plasma change in hypertensive patients. Methods At the Quzhou City central hospital between 2014 and 2015, 526 cases of hypertensive patients as hypertensive group and 546 cases of people with normal blood pressure in the healthy check-up as normal blood pressure group were investigated with physical examination, blood biochemical index detection and the serum cystatin C level detection. The analysis of the relationship between the serum cystatin C level and atherogenic index of plasma among two groups was done. Results The evidence that the serum cystatin C level between hypertensive group and normal blood pressure group shows respectively as: 1.12±0.44 (mg/L) and 0.81±0.22 (mg/L), atherogenic index of plasma shows respectively as:0.68±0.03 and -0.22±0.02, both differences were statistically significant (P<0.01) . As the serum cystatin C level increased, the risk of hypertension increased (OR=20.06, 95％CI: 12.67-31.76) . Plasma arteriosclerosis index in hypertensive group was correlated with systolic blood pressure, body mass index, total cholesterol, triglyceride, high-density lipoprotein, LDL cholesterol, and uric acid level respectively, all differences were statistically significant. In addition to the above indicators, the serum cystatin C level in hypertensive group was correlated with serum creatinine level (all P<0.05) . Conclusion The serum cystatin C level and plasma arteriosclerosis index in patients with hypertension both were higher than those with normal blood pressure. These two indicators were correlated with systolic blood pressure and multiple blood lipid indicators. They could be used to monitor arteriosclerosis and target organ damage in patients with hypertension.
ABSTRACT
Objective To observe the changes of shock index (SI) and diastolic blood pressure (DBP) in postpartum hemorrhage patients, and the explore their relationship with postpartum hemorrhage and the clinical significance of early warning of hemorrhage risk. Methods 402 patients with postpartum hemorrhage (within 24 hours after delivery, the amount of bleeding in vaginal delivery≥500 mL, and the amount of bleeding in caesarean delivery≥1 000 mL) admitted to the obstetrics ward of Affiliated Hospital of Hangzhou Normal University from January 2014 to December 2017 were selected as the objective group and 416 without complications during delivery were selected as the control group in the same hospital at the same period. Clinical data in the two groups before and after childbirth was collected, including age, pregnancy week, 24-hour blood loss, and hemoglobin (Hb), whole blood cell parameters, heart rate (HR), systolic blood pressure (SBP), DBP, SI, blood urea nitrogen (BUN), serum creatinine (SCr) within 24 hours before and after delivery, and postpartum 24 hours and prenatal DBP difference (ΔDBP). The differences of indicators were compared between the two groups. Pearson method was used to analyze the correlation between the postpartum DBP and SI in the objective group. Ordinal regression model was used to analyze the early warning risk factors of each index to postpartum hemorrhage. Results Compared with the control group, older age (years: 29.29±5.01 vs. 28.05±4.46), more pregnancies (times: 2.68±1.42 vs. 2.33±1.28), shorter gestation weeks (weeks: 38.33±3.57 vs. 39.05±1.40), more 24-hour blood loss (mL: 726.57±467.66 vs. 244.49±50.25) in the objective group were significant differences (all P﹤0.01). Postpartum hemorrhage patients were successfully hemostatic, no maternal and perinatal death was found in the two groups. Compared with the control group, DBP was significantly decreased at 24 hours after delivery in the objective group [mmHg (1 mmHg = 0.133 kPa): 71.19±12.55 vs. 75.68±8.96, P < 0.05], and ΔDBP was significantly increased (mmHg: 5.39±3.93 vs. 0.67±0.33, P < 0.01). In addition, compared with the control group, SI and HR were significantly increased in the objective group [SI:0.80±0.15 vs. 0.72±0.11, HR (bpm): 91.56±13.37 vs. 82.96±11.76, both P < 0.05], Hb, red blood cell count (RBC), platelet count (PLT) and SBP were significantly decreased [Hb (g/L): 91.30±13.41 vs. 112.30±13.41, RBC (×1012/L): 3.74±0.38 vs. 4.59±0.45, PLT (×109/L): 173.02±59.08 vs. 182.09±54.76, SBP (mmHg):115.13±9.27 vs. 117.94±11.66, all P﹤0.05]. Correlation analysis showed that postpartum DBP was negatively correlated with SI, 24-hour blood loss, ΔDBP, BUN and SCr (r value was -0.419, -0.268, -0.490, -0.108, -0.163, respectively, all P < 0.05), and positively correlated with SBP, Hb and RBC (r value was 0.739, 0.125, 0.096, respectively, all P < 0.05). It was shown by Ordinal regression analysis that the risk of postpartum hemorrhage was significantly increased when ΔDBP≥9.32 mmHg [relative risk (RR) = 2.64, 95% confidence interval (95%CI) =1.94-3.34, P = 0.000], SI≥0.95 (RR = 1.78, 95%CI = 1.01-2.55, P = 0.000), DBP≤59.64 mmHg (RR = 0.86, 95%CI = 0.31-1.41, P = 0.000), SBP≤105.86 mmHg (RR = 0.63, 95%CI = 0.18-1.07, P = 0.000), Hb≤77.89 g/L (RR = 1.68, 95%CI = 0.99-2.38, P = 0.000), and ΔDBP≥9.32 mmHg was the most effective early warning effect. Conclusions Combined with clinical manifestations of patients with postpartum hemorrhage, SI and DBP can be used as an important reference indicator for the observation of postpartum hemorrhage conditions. ΔDBP≥9.32 mmHg can be used as the risk factors of the patient with postpartum hemorrhage.
ABSTRACT
Objective To explore the pathological changes of liver fibrosis of patients with schistosomiasis liver fibrosis.Methods Between January 2003 and January 2009,microstructure retrospective observation of liver biopsy pathological paraffin specimens by optical microscope was carried out in 9 cases of patients with schistosomiasis liver fibrosis in Quzhou people's hospital internal medicine.Then those paraffin blocks were changed to resin embedding blocks and superfine slices were made.Ultrastructure observation by electronic microscope was carried out.Results Visible fibrous scar formation and fiber calcified nodule eggs in microscopic structure of liver tissue in 9 cases of patients with schistosomiasis liver fibrosis were observed.Ultrastructural observation of the 9 cases of patients with schistosomiasis liver fibrosis showed that most of the liver cell profile was clear,liver cell nucleus gap expanded,the number of rough endoplasmic reticulum decreased,swollen mitochondria crest occurred,collagen deposited around hepatic sinus and surroundings and collagen fiber bundle around small veins extended to hepatic lobule and surroundings,and calcified nodule eggs were not easy to find.Conclusions Under an electron microscope,diseased tissue cells can be observed at subcellular level or organelle level,which provides more insight into the pathology of schistosomiasis liver fibrosis.Calcified egg nodules are easily found by an optical microscope other than an electron microscopy.The two can complement each other.

ABSTRACT
The fall risk was evaluated with Modified Falls Efficacy Scale (Chinese version) in 426 elderly hypertensive patients (hypertensive group) and 436 elderly people without hypertension (control group) from rural communities in Zhejiang Quzhou areas.The fall risk scores were compared between hypertensive group and control group ; and also between patients with history of falls and those without falls.The results showed that the average score was 8.62 ± 2.15 in hypertensive group and 9.35 ± 1.35 in control group (P ＜ 0.01).The average score was 6.94 ± 1.85 in hypertensive patients with history of falls (n =112) and 9.22 ± 1.42 in without history of falls (n =314) (P ＜0.01).Our study suggests that there is a higher fall risk in elderly hypertensive patients than in elderly people without hypertension; and fall risk assessment with Modified Falls Efficacy Scale (Chinese version) can be used for prediction of fall for the elderly people in rural community.
ABSTRACT
Objective To investigate the expressions of platelet activation-dependent granule membrane protein and platelet-derived growth factor receptor-αB, and the ultra-microstructure changes of platelets in patients with acute ST-segment elevation myocardial infarction(STEMI). Method The expressions of platelet activationdependent granule of glycoprotein (CD62P)and platelet derived growth factor receptor αβ subtype (PDGFR-αβ)of platelets in peripheral blood in 36 patients with acute ST-segment elevation myocardial infarction(STEMI) hospitalized and another 34 healthy subjects over the same period (control group) were investigated by flow cytometry and data were analyzed. The changes of ultra microstructure and activity of blood platelets in those patients and control group were observed under the scanning electron microscope. Results The expressions of CD62P and PDGFR-αβin patients with STEMI group before treatment were (3.65 ± 1.87) % and (0.43 ± 0.39) %, respectively, and those after treatment were (0.96 ± 0.79) % and (0.28 ± 0. 24) %, respectively, whereas those in control group were (0.67 ± 0.35) % and (0.27 ± 0.22) %, respectively, which were much lower in control than those in patients with STEMI before treatment (P ＜ 0.01 or P ＜ 0.05) respectively. There were statistically significant differences in the expressions of CD62P and PDGFR-αβ in patients group between pre-treatment and posttreatment (P ＜0.01 or P ＜0.05), respectively. Obvious ultra-microstructure changes of platelet surface in patients with STEMI group were observed. Conclusions Due to platelet activation in AMI, the expressions of CD62P can be used as effective indicators for monitoring coronary heart disease, and the PDGFR-αβ can be used as a reference indicator. The platelet surface ultra-microstructure changes during platelet activation in patients with AMI can be found by scanning electron microscopy.
ABSTRACT
<p><b>BACKGROUND</b>Non-small cell lung cancer (NSCLC) is the leading cause of cancer mortality worldwide. Platelet activation may play an important role in pathologic progress in lung cancer. In this study, we aimed to clarify the influence of activated platelets on lung cancer generation and growth, and the relationship among these functional and ultrastructural changes of platelets and the severity of pathogenetic condition in these patients with NSCLC.</p><p><b>METHODS</b>One hundred and thirty-six cases of patients with pathologically confirmed NSCLC were included in this study. Fifty-four healthy people were enrolled as controls. The change of ultra microstructure and activity of blood platelets were observed under the transmission and scanning electron microscope. Simultaneous determination of plasma granule membrane protein 140 (GMP-140) was made.</p><p><b>RESULTS</b>Transmission electron microscopy showed remarkable changes of ultra microstructure of platelets in patients with NSCLC, including swelling, increase of a-granules, vesicles, and glycogenosome. Scanning electron microscopy showed many more surface processes and wrinkles on platelets in patients with NSCLC. The reference plasma levels of GMP-140 of healthy controls were (18.2 +/- 2.7) microg/L. The plasma levels of GMP-140 in patients with NSCLC were (47.8 +/- 12.3) microg/L, which were much higher than those of the controls. There was a medium positive correlation between plasma levels of GMP-140 and amount of a-granules (r = 0.514, P < 0.01) and a high positive correlation between plasma levels of GMP-140 and area of platelet (r = 0.84, P < 0.01) in patients with NSCLC. The Kaplan-Meier survival curve analysis showed significant shift to the left in patients with NSCLC whose a-granules per platelet were 19 or more compared to those 18 or less (Log rank statistic, chi(2) = 17.38, P < 0.01).</p><p><b>CONCLUSIONS</b>There are significant activated changes of ultra microstructure and increased activity of blood platelets in patients with NSCLC. These activated platelets may play an important role in the generation and growth of lung cancer. These changes can be used as a diagnostic index of severity, progression, and prognosis of NSCLC.</p>
