Objective To observe the influences of stemona alkaloids on esterase isozymes activities and glycogen content of Oncomelania hupensis in order to explore the molluscicidal mechanism of stemona alkaloids.Methods O.hupensis snails were immersed in the liquid of stemona alkaloids at the concentration of 6.5 mg/L(72 h LC50),the surviving ones were picked out and sampled after being immersed for 12,24,48,72,96 h,then PAGE and anthrone colorimetry methods were used to observe the changes of liver esterase isozymes activities and tissue glycogen content of O.hupensis during the immersion period.A group of snails immersed in de-chlorinous water served as control.Results Esterase isozymes activities firstly increased,and then decreased until almost lost completely during the 96 h immersion period.Meanwhile,glycogen content gradually decreased as the immersion time extended.After being immersed for 96 h,glycogen content decreased by 72.00% compared with the control group.Conclusion Stemona alkaloids could inhibit the viability of O.hupensis by causing decrease of esterase isozymes activities and glycogen content.

ObjectiveTo evaluate clinical significance of serum free light chains (sFLC) in diagnosis and response to the therapies of patients with multiple myeloma (MM).MethodssFLC (κ,λ and κ / λ ratio)were examed by immumoassay from 62 patients with MM at different stage. The results were analyzed associated with clinical data,and 35 cases of chronic renal failure(CRF)patients and 62 cases of healthy donors were taken as controls.ResultsMedium sFLC of normal κ value was (13.25±6.46) mg/L,λ value was (18.39±11.42) mg/L; and κ / λ ratio was (0.97±0.64) mg/L (range 0.33-1.61).sFLC κ and λ of CRF patients were (200.01±299.87) mg/L,(191.02±245.98) mg/L,significantly higher than that of the normal control group (t =-17.804,-16.894,both P ＜ 0.001),but the κ/λ ratio was at normal range (1.11±0.29).κ value range was at 16.20- 35 250 mg/L in newly diagnosed intact immunoglobulin MM patients with IgGκ,IgAκ and IgDκ type.The range of λ values was 15.70-4885 mg/L in IgGλ,IgAλ,IgDλ type,and κ/λ ratio was abnormal in 96.5 ％ (55/57) patients (＜0.5 or ＞1.5).The κ,λ value and κ/λ ratio were close to that of the normal after remmision.ConclusionsFLC ( κ,λ,and κ / λ ratio) are very good monitoring markers for MM.

Objective To observe the changes of the skeletal development related cells after dihydroorotate dehydrogenase (DHODH) deficiency.Methods The DHODH expression in MC3T3-E1 cells derived from mouse calvaria osteoblast precursor cells was inhibited by specific small interfering RNAs (siRNAs),and cell proliferation,ATP production and expression levels of bone-related genes were investigated in these cells.Results After reducing the DHODH expression by using specific siRNAs,cell proliferation was inhibited and cell cycle was arrested at G1/S stage.In addition,the ATP production was reduced in whole cells,especially in mitochondria.Furthermore,the expression levels of Runt-related transcription factor 2 (Runx2) and osteocalcin (Ocn) mRNAs in the DHODH inhibition group were decreased compared with the control group.Conclusion Inhibiting DHODH protein affects the differentiation and maturation of osteoblasts.The mitochondrial dysfunction in osteoblasts may be one of causes leading to the abnormal bone formation in Miller syndrome.

The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

Objective To investigate the age distribution and types of human papillomavirus (HPV) cervical infection in patients in Wuhan region, so as to provide scientific basis for the prevention and treatment of HPV infection and cervical cancer.Methods 9 915 exfoliated cervical cell specimens from patients in Wuhan Medical and Health Center for Women and Children between January 2015 and March 2016 were performed HPV genotyping (21 subtypes), clinical data of 1 732 HPV positive cases were statistically analyzed.Results HPV-positive rates in ≤25, 26~, 36~, 46~, and ≥56 age groups were 22.15%, 15.90%, 17.04%, 19.97%, and 17.57%,respectively (χ2=36.587,P<0.01),HPV-positive rates in ≤25 and 46~ age groups were both higher than other age groups.There were significant differences in single infection and multiple infection rates among different age groups respectively(χ2=14.39, 36.51,respectively, both P<0.05),single infection rate was highest in 46~ and ≤25 age groups (15.41% and 15.24% respectively);multiple infection rates was highest in ≤25 and ≥56 age groups (6.90% and 5.86% respectively).The percentage of single infection and multiple infection were 75.58% and 24.42% respectively, the major single infection type was HPV high-risk subtype (84.34%),the major multiple infection types were high-risk and high-risk compound subtype as well as high-risk and low-risk compound subtype, accounting for 60.52% and 38.77% respectively.The main single infection types were HPV high-risk subtypes 33, 68, 31 and 16, as well as and low-risk subtype 11, the ratios of single infection to multiple infection were 3.13, 2.03, 1.71, 1.67 and 2.00 respectively.Conclusion Cervical infection rates in women in Wuhan region is high in ≤25 and 46~ age groups, there are differences in the distribution of different HPV subtypes of single infection and multiple infection.

Objective: To analyze the association of thrombocytosis with the prognosis of patients with gastric cancer.Methods: The clinical materials of 782 patients with gastric cancer who underwent initial surgery in our hospital between January 1995 and December 1999 were retrospectively analyzed.Kaplan- Meier and Log-Rank test were used to analyze the data.Prognostic factors were analyzed by multivariate Cox proportional hazards model.Results: Thrombocytosis oc-curred in 11.4% (87/782) patients.The platelet level was not significantly different among patients of different gender, tumor stage, and histological differentiation (P>0.05).However, a significant difference was observed in the platelet level among patients with different age and surgical approach (P<0.05).The 1-, 3-, and 5-year survival rates were 75.0%, 40.1% and 28.9% in patients without thrombocytosis and 52.8%, 16.9%, and 13.5% in patients with thrombocytosis (P=0.002).Univari-ate analysis showed that histological differentiation, pathological stage, surgical approach and thrombocytosis significantly affected the survival of patients.While age and gender had no significant impact on patient survival.Multivariate analysis showed that pathological stage, surgical approach, and thrombocytosis were independent prognostic factors for gastric can-cer.The relative risk of death of patients with thrombocytosis was elevated by 1.454 times (RR=1.454, 95% CI: 1.135～1.861, P=0.005).Conclusion: Thrombocytosis is an independent prognostic indicator for the survival of initially treated pa-tients with gastric cancer.

Objective To explore the influence of obstruction sleep apnea syndrome (OSAS) on plasma cystatin C (CC) levels in patients with primary hypertension.Methods A total of 244 cases of primary hypertension patients was chosen.The patients were divided into observation group (with OSAS) and control group (without OSAS) according to apnea hypopnea index (AHI).The observation group was then divided into three subgroups:mild OSAS group,moderate OSAS group,and severe OSAS group.The levels of CC were compared.Results First,the plasma CC levels in patients with primary hypertension had no statistical significance in the differences among different grades of hypertension (P ＞ 0.05).Second,CC levels of observation group were significantly higher than control group (P ＜ 0.05).Third,CC levels of the severe group were higher than the moderate group,and the plasma CC levels of the moderate group were also higher than the mild group and control group.Rank correlation analysis and comparison of CC levels and AHI showed that CC levels were positively correlated with AHI (r =0.585,P ＜ 0.01).However,there were no statistically significant differences between CC levels of the mild OSAS group and control group (P ＞ 0.05).Conclusions The patients with OSAS and primary hypertension had higher levels of CC,and aggravated with the progress of the degree of obstruction.CC may be involved in the progression of the disease,a high level of CC may aggravate the condition,it should be early prevention and treatment.
