Objective To investigate the clinical value of CA125, CA153, HE4 joint detection in diagnosis of gynecological malignancies.Methods 70 cases of gynecological malignancies were selected from our hospital in 2013, 72 cases of benign gynecological diseases selected in the same period, and 70 healthy controls were selected. The expression levels of CA125, CA153 and HE4 were detected and statistically analyzed.Results The positive rate of serum CA125 in the gynecological malignancies group was higher than that in the benign gynecological disease group (p <0.05).The positive rate of serum HE4 in the gynecological malignancies group was higher than that in the benign gynecological disease group (p <0.01).The positive rate of CA125, CA153, HE4 joint detection in the gy-necological malignancies group (up to 72.9%) was also significantly higher than that in the benign gynecological dis-ease group (p <0.01).Conclusion is a single tumor marker with the highest sensitivity and specificity for diagno-sis of gynecological malignancies.CA125, CA153, HE4 joint detection can improve the positive rate of diagnosis of gynecological malignancies.

Objective To investigate the effectiveness of early minimal enteral feeding′s prevention and cure of feeding intolerance of very low birth weight infants (VLBWs).Methods A total of 45 VLBWs from the neonatal intensive care unit(NICU) of the second people′s hospital of Shantou,were included,from 2011 Jan to 2012 Dec. 23 infants in the intervention group which were hospitalized in 2012,received early minimal enteral feeding (MEF), while 22 infants in the control group which were hospitalized in 2011,received routine feeding .The incidence of feed-ing intolerance of the two groups was observed .Results The incidence rate of feeding intolerance was 21.74%(5 cases) in the intervention group and 72.73%(16 cases) in the control group.The incidence rate of feeding intol-erance of the intervention group was lower than that of the control group obviously and the difference was statistical significance(P<0.05).The time to achieve full enteral feeding of the intervention group [(28.22 ±1.97)days] was significantly shorter than that of the control group [(34.23 ±3.10)days](P<0.05).Conclusion An early MEF is beneficial to reduce the occurrence rate of feeding intolerance ,achieve full enteral feeding sooner ,decrease the length of hospital stay and improve the life quality of VLBWs .

Objective To evaluate the imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza.Methods CT and MRI brain imaging data of three children acute necrotizing encephalopathy caused by A H1N1 influenza virus and proved by clinical and laboratory investigation were analyzed.All the three children got CT and MRI scan because of coma while in hospital.Results All cases represented multifocal damage,and some were symmetrical.Bilateral thalamencephalons were involved in the all cases.Bilateral grey and white matters of frontal lobe,temporal lobe,parietal lobe and occipital lobe,and hippocampi,putamina,external capsule,brain stem,bilateral cerebellum,could be seen multifocal damage,and some were symmetrical.All the cases showed brain swelling in varying degrees.These region presented low density in CT,hypointensity on T1 weighted series and hyperintensity on T2 weighted series and FLAIR series in MRI.Conclusion The imaging features of acute necrotizing encephalopathy caused by children A H1N1 influenza represented multifocal and symmetrical damage and brain swelling.It may be characteristic that bilateral thalamencephaloas were involved.The patient was serious,and fatality rate was high.So we should pay much attention to acute necrotizing encephalopathy caused by children A H1 N1 influenza.

Objective To evaluate the effects of propofol and sevoflurane anesthesia on cognitive function and amyloid beta protein ( Aβ) deposition in hippocampi of aged mice. Methods Thirty?six SAMP8 mice, aged 6 months, weighing 29-32 g, were randomly assigned into 4 groups ( n=9 each) using a random number table: control group ( group C ) , propofol anesthesia group ( group P ) , sevoflurane anesthesia group (group S) and propofol plus sevoflurane anesthesia group (group PS). In group P, propofol 140 mg∕kg was injected intraperitoneally, when righting reflex occurred, additional propofol 70 mg∕kg was given, and when it occurred again, additional propofol 40 mg∕kg was given. Group S continuously inhaled 1% sevoflurane for 120 min. Group PS continuously inhaled 2% sevoflurane for 120 min, and when righting reflex occurred, additional propofol 40 mg∕kg was given. Anesthesia was maintained for 120 min in P, S and PS groups. Before anesthesia and at 7, 14 and 28 days after anesthesia, Morris water maze test was performed, and the escape latency was recorded. Hippocampi were obtained to determine the expression of Aβ using immuno?histochemistry. Results Compared with group C, the escape latency was significantly prolonged at 7 days after anesthesia, and the expression of Aβwas up?regulated at 7, 14 and 28 days after anesthesia in group S, and no significant change was found in the parameters mentioned above in P and PS groups. Compared with the value at 7 days after anesthesia, the expression of Aβ was significantly down?regulated at 14 and 28 days after anesthesia in group S, and no significant change was found in the expression of Aβ at 14 and 28 days after anesthesia in C, P and PS groups. Conclusion Although sevoflurane anesthesia promotes Aβ deposition in hippocampi, it only causes short?term cognitive dysfunction, however, anesthesia with propofol or with propofol in combination with sevoflurane produces no influence in aged mice.

Objective To evaluate the effects of different head-down tilt (HDT) angles on respiratory mechanics and cerebral circulation during laparoscopic radical resection of rectal carcinoma in the patients.Methods Thirty patients of both sexes,aged 40-64 yr,of ASA physical status Ⅰ or Ⅱ,with body mass index ＜ 30 kg/m2,scheduled for elective laparoscopic radical resection of rectal carcinoma,were included in the study.Anesthesia was induced with midazolam,fentanyl,propofol and cis-atracurium and maintained with targetcontrolled infusion of propofol and remifentanil and cis-atracurium when needed.At 5 min after supine position,5 min after 30° HDT,5 min after 35° HDT,5 min after 40° HDT,and 30 min after pneumoperitoneum (T1-5),airway pressure (Paw),peak airway pressure (PIP),lung compliance (Cpat) and jugular bulb blood pressure (JBP) were recorded.Blood samples were taken from the radial artery and jugular bulb for blood gas analysis and arterial partial pressure of oxygen (PaO2),partial pressure of carbon dioxide in artery (PaCO2),arterial oxygen saturation (SaO2),jugular bulb oxygen partial pressure (PjvO2),and jugular bulb venous saturation (SjvO2) were recorded at each time point mentioned above.Results Paw,PIP,MAP,PaCO2,JBP,PjvO2 and SjvO2 were significantly increased as compared with those obtained when the patients were in supine position,increased gradually with the increasing HDT angles,and decreased to the level obtained when the patients were in supine position at 30 min after pneumoperitoneum.Cpat and PaO2 were significantly decreased as compared with those obtained when the patients were in supine position decreased gradually with the decreasing HDT angles,and increased to the level obtained when the patients were in supine position at 30 min after pneumoperitoneum.Conclusion HDT-induced effects on respiratory mechanics and cerebral circulation increase with increasing angles during laparoscopic radical resection of rectal carcinoma; thus the optimum HDT angle is smaller than 40° for the patients undergoing this kind of surgery.

Objective To investigate the protective effects of creatine phosphate pretreatment on circulato ry function in prone position in elder patients with general anesthesia.Methods Forty patients in ASA physical status Ⅰ or Ⅱ of male and female,aged 60 to 75 years undergoing percutaneous nephrolithotripsy in prone position,were randomly divided into two groups (n =20 each):the control group (gToup N) and the creatine phosphate group (group P).In the group P,creatine phosphate sodium (30 mg·kg-1 in 50 mL normal saline) was continuous infused at a speed of 100 mL· h-1,while only normal saline 50 mL in the group N at the same time.HR,MAP,CO,SV,CVP,Pulse Pressure Variation (PVV) and Systemic Circulation Resistance (SVR) were monitored and recorded at 1 min before prone position (T0) and 1 min (T1),3 min (T2),5 min (T3),10 min (T4) after prone position.The requirement for vasoactive agents were also recorded.Results Compared with T0,HR began to increase significantly at T1 in the group N(P ＜ 0.05),while MAP,CO and SV began to decrease at T1 to T3,and CVP,PVV and SVR began to increase significantly at the same time in the group N (P ＜ 0.05).Compared with the group N,MAP,CO and SV were decreased,PPV,CVP and SVR were increased significantly at T1 to T2 in the group P (P ＜ 0.05).The requirement for vasoactive agents in the group P was obviously lower than that in the group N (P ＜ 0.05).Conclusion Creatine phosphate pretreatment can stabilize the hemodynamic change effectively,and prevent the adverse cardiovascular events caused by prone position in elder patients with general anesthesia.

To investigate the influence of recombinant adenovirus carrying tissue inhibitor of metalloproteinase-3 (RAdTIMP-3) on the main compositions of rabbits intervertebral discs and to assess its potential in treatment for intervertebral disc degeneration.[Method]RadTIMP-3 and empty adenovims vector with Lac-Z gene (Rad66) was propagated in 293 Cells and was purified, identified and tittered. Thirty Japanese white rabbits were randomly divided into 5 groups. And 25 μl of various reagents were injected to the L4、5 and L5、6 intervertebral discs of the rabbits as follows:normal saline in group 1, 1.0×1010 OPU/ml of RAd66 in Group 2, and 1.0×1010 OPU/ml of RAdTIMP-3 in group 3, 4 and 5. The intervertebral discs of each group were collected after 2, 2, 1, 2 and 4 weeks after injection respectively.Then X-gal staining, And Group 1, RT-PCR for TIMP-3 and aggrecan core protein,TUNEL staining, immunohistochemical staining for TIMP-3 and type I! Collagen and Safranin O-Fast green staining was carried out to assess the effects of RadTIMP-3 transfection.[Result](1)concentration of RAdTIMP-3 reached 1.9×1012 OPU/ml after propagation and purification. (2)RT-PCR shows that the expression of TIMP-3 was significantly raised in group 3, 4, 5, as compared with group 1 or 2. And the expression of core protein gene in group 3, 4, 5 increased slightly than in group 1 and 2. (3) TUNEL staining revealed that there was not significant difference between the positive-staining rates of any two of the groups. (4)TIMP-3 staining exhibited an obvious increase of positive-staining rates in group 3, 4 and 5 as compared with groupi or 2. The staining density of Safranin O-Fast Green staining and immunohistochemical staining for type II collagen of group 5 was obviously higher than that of group 1 or 2.[Conclusion]RAdTIMP-3 can express widely and safely in rabbit intervertebral discs, and improve the quantity and quality of matrix. It has the potential to be used in treatment for intervertabral disc degeneration.

Objective To valuate the left ventricular function and myocardial fibrosis using Dopple tissue imaging(DTI) and integrated backscatter(IBS) in diabetic cardiomyopathy(DCM) rats. Methods Diabetes mellitus(DM) in healthy male SD rats was induced by single injection of streptozotocin (STZ,Sigma) into intraperitoneal at a dose of 65mg/kg body weight. Left ventricular fractional shortening (LVFS),ratio of peak early to late diastolic mitral inflow velocity(E/A) by color Doppler flow imaging-pulsed wave (CDFI-PW), ratio of peak early to late diastolic mitral annulus velocity (Ea/Aa) by DTI,myocardial calibrated IBS (IB%), cyclic variation of IBS(CVIB) by IBS, were determined in rats of 4,12 and 24 weeks after DM was induced. Heart weight index(HWI), Masson's trichrome staining, expression of connective tissue growth factor(CTGF) and activity of sarcoplasmic reticulum Ca2+ -ATPase(SERCA2a) in heart were measured, while the age-matched health rats served as control group. Results ① Diastolic dysfunction of left ventricular was found in diabetic rats detected by CDFI-PW(E/A<1) at the 4th week,and developed gradually. Pseudonormal filling(E/A>1) was found in major diabetic rats at the 24th week,which could be identified by DTI(Ea/Aa<1). The IB% of left ventricular posterior wall was significantly higher in diabetic rats than those in the control group( P<0.05), but the CVIB of the 24th week diabetic rats was lower(P<0.05). The LVFS had no great alteration in six groups(P>0.05).②Compared with the control group, the activity of SERCA2a was reduced, while HWI, collagen volume fraction(CVF),perivascular collagen area(PVCA) and the expression of connective tissue growth factor(CTGF) protein in heart were increased in diabetic rats (P<0.05), and correlation between IB% and HWI, CVF, PVCA,CTGF was significant (P<0.05). Conclusions DTI and IBS can assess early left ventrieular diastolic function and fibrosis of diabetic cardiomypathy in STZ-induced diabetic rats. DTI echoeardiography can identify "pseudonormal" mitral inflow patterns. DCM may be relatived with overexpression of CTGF and decreasion of SERCA2a activity.
