Objective To explore the effects of light on the expression patterns of clock and clock-related genes in peripheral lymphocytes.To develop basic knowledge needed for clinical application of the circadian clock.Methods One hundred Sprague-Dawley rats were housed under constant dark(DD)or normal light-dark(LD 12:12)conditions for six weeks.Peripheral iymphoeytes were collected at different time points.The expression level of the clock gene and melatonin receptor genes mt1 and mt2 were detected using semi-quantitative RT-PCR.The data were analyzed with cosine software.Results Circadian expression of the genes was observed in both groups,but the peak phase,amplitude and strength of expression of each gene differed with the light conditions.Conclusion Light influences the expression of clock and clock-related genes in rats' peripheral lymphocytes.The clock gene might play an important role in regulating the expression of mt1 and mt2.

Objective To explore the value of serum procalcitonin detection in judging whether severe patients complicate with infection.Methods 188 patients in the intensive care unit (ICU)were collected and divided into the infection and non-infection groups.The serum procalcitonin(PCT),C-reactive protein(CRP),total number of white blood cells(WBC)and neutrophile cell ratio were simultaneously monitored;41 cases in the infection group dynamically monitored PCT and related indicators for continuous 1-6 d and the statistical analysis was conducted.Results The age,PCT and CRP had statistically significant differences between the infection group(112 cases)and non-infection group(76 cases).Except the correlation of PCT and CRP in the infection group showing statistical significance,the comparison of the other indicators had no statistical differences.In the infectors,the PCT value comparison between on 1 d and 2 d in the hospital discharge group(32 cases)and the death group (9 cases)showed P >0.05,the PCT value comparison between on 3-6 d showed P <0.05.Conclusion Serum PCT is an effective indicator to judge whether se-vere infected patient has infection and is significantly superior to the traditional inflammatory indicators.Dynamically monitoring the PCT level in the critical patients has a certain value to judge the control situation of infection.

Objective To estimate the marginal value of the chemical oxygen demand (COD) in drinking water by evaluation of uncertainty. Methods According to Evaluation and Expression of Uncertainty in Measurement (JJF1059-1999), analysis of measure uncertainty of the chemical oxygen demand determined by acidic potassium permanganate titrate prescribed in Sanitary Standards for Drinking Water (2001) was conducted. Results The type A relative standard uncertainty was 0.584%, type B was 0.781%, in which the sub-item uncertainty led by using 25 ml burette was 0.708%, the water sample volume was 0.056%, the adjusted potassium permanganate standard solution was 0.325%; the relative combined standard uncertainty was 0.975%, the expanded uncertainty was 1.95%. Conclusion According to the result of the uncertainty (3.08?0.06) mg/L, COD in the polluted sample exceeds the limit, the use of 25 ml burette produced the most contribution to the uncertainty.

Objective To study the factors associated with post-operattve renal function injury after laparoscopic nephron-sparing surgery(LNSS)for tumors. Methods Fifty consecutive patients were enroned in a prospective protocol and underwent LNSS.Preoperative and postoperative renal scintigraphic scan was performed in all patients. 99 Tcm-diethylenetetraminepentacetic acid scan was performed in all patients.Linear correlation and multivariate regression model were used to analysis the factors associated with postoperative renal damage.Twenty consecutive patients associated with risk factors were followed-up.These data in GFR were monitored at the preoperative,1 week and 3 months after operation.The duration Warm ischemia was recorded. Results In selected patients,assessed by renal scintigraphy,the function of the operated kidney was reduced by a mean of 24%.Linar correlation analysis showed that there was positive correlation between the age,tumor size,duration of warm ischemia and postoperative renal function injury.Furthermore,multivariate Legression analysis revealed that the duration of warm ischemia was the independent risk factor of postoperative renal damage.Twenty consecutive patients were included in this protocol.There was a significant difference between vessel clamp time≤30 min and vessel clamp time＞30 min.Renal scan data did not reveal any significant decrease in GFR in the affected kidney at 3 months after surgery for the patients whose yesscl clamp time less than 30 min.Renal function damage could not recover in the patients over 70 years with longer than 30 min warm ischemia or with longer than 60 min warm ischemia. Conclusions This paper evaluated renal function on the affected side before and after surgery by measuring renal function with renal scintigraphy using99 Tcm-DTPA.Risk factors for renal dysfunction in the affected kidney after LPN are age over 70 years with more than 30min warm ischemia time,and a warm ischemia time longer than 60 min.

Objective:To investigate relationship between parents'marital relationship and intergenerational transmission of value orientation of marriage and love among college students.Methods:Totally 712 families inclu-ding a college student and his/her parents from 9 universities were surveyed.The Marital Health Test (MHT)was used to assess parents'marital relationship and transmission of value orientation of marriage and love from father and mother.The structural equation modeling and stepwise multiple regression were used to analysis the relationship between parents'marital relationship and intergenerational transmission of value orientation of marriage and love a-mong college students.Results:Moderate correlations (r =0.24 -0.58,Ps <0.01 )were found between parents'marital relationship and transmission of value orientation of marriage and love from father and mother.Path analysis suggested that paths from parents'marital relationship to paternal transmission and maternal transmission were statis-tically significant (path coefficient was 0.59 and 0.75).Grouping regression analysis showed that the influences of parents 'marital relationship of same-sex transmission (R2 =0.49,0.35 ) were greater than opposite-sex transmission.Conclusions:The findings indicate that parents'marital relationship could facilitate the intergeneration-al transmission of value orientation of marriage and love.Moreover,the influences of parents'marital relationship of same-gender transmission may be greater than opposite-sex transmission.

Objective To compare the effects of oral Sildenafil(SIL)and intravenous prostaglandin E_1(Alprostadil,PGE_1)in treatment of postoperative pulmonary hypertension(PH)associated with congenital heart defects(CHD).Methods Data were collected from 24 children with postoperative mPAP≥35 mmHg in our hospital between August 2004 and March 2005.These children were randomly divided into three groups:8 children(group A)initially received SIL(0.35 mg/kg,orally by nasal gastric tube),followed by the addition of intravenous PGE_1(20 ng/kg per min)at 40 min.The second group of 8 children(group C)initially received intravenous PGE_1 followed by the addition of SIL at 20 min(dose as above).And remains(group B)were placebo-controlled.The changes of hemodynamic variables,arterial blood gas,lung static compliance(C)and work of breathing(W)were measured after drugs were given.Results Compared with group B,the mPAP and mPAP/mSAP was significantly reduced(P

AIM: To explore the effect of early posterior approach vitrectomy in the treatment of penetrating ocular trauma with intraocular foreign body.METHODS: Totally 10 cases of penetrating ocular trauma with intraocular foreign bodies(IOFB) in the past two years were included.Emergency vitrectomy, intraocular foreign body removal and silicone oil tamponade were performed by the same surgeon.Antibiotics and steroids were given after surgeries.Retinal photocoagulation was done according to fundus conditions after surgeries.RESULTS: One patient combined with preoperation endophthalmitis and severely damaged retina failed to recover, eventually came to phthisis bulbi.Vitrectomy and IOFB removal were all successfully performed in the other patients.The postoperation follow-up time was 3-18mo.Two of the patients received secondary vitrectomy and silicone replacement surgeries due to recurrent retinal detachment.The remaining patients had no further bleeding with intraoclar pressure(IOP) 8-21mmHg.At the last follow-up, three of them gained best corrected visual acuity better than 0.1, two patients had visual acuity of 0.01 to 0.1 and four patients had poor visual acuity of light perception to FC/50cm because of macular damage.The patient with phthisis bulbi had no light perception.CONCLUSION: Early vitrectomy, foreign body removal and silicone oil tamponade is an effective treatment for patients with penetrating eyeball injury with IOFB.
