Essential hypertension is a multifactorial disease. Many experimental studies have elucidated the role of oxidative stress and atherosclerosis in the pathogenesis of essential hypertension. Apolipoprotein E is a plasma protein that is found to have antioxidant properties, and it also protects against atherosclerosis. Interestingly, the biological function of apolipoprotein E is strongly affected by polymorphisms in its gene. Based on this evidence, our aim was to investigate the association of apolipoprotein E gene polymorphisms with essential hypertension. Methods: This study was conducted on 70 hypertensive patients and 73 control participants recruited from the Balok governmental health clinic in Kuantan, Pahang. The polymerase chain reaction restriction fragment length polymorphism assay (PCR-RFLP) was used for determination of the apolipoprotein E genotype. Our results were also verified later by direct sequencing of the amplicons. Results: There was no significant association of apolipoprotein E allele or genotype frequencies with hypertensive disease or blood pressure levels, although the E4 allele was slightly more frequent in the hypertensive patients than in the control group (OR=1.055; 0.471–2.359, CI 95%). To improve the precision of the study and to settle the controversies among similar studies meta-analysis was performed; however it revealed a net nonsignificant association between the apolipoprotein E4 allele with essential hypertension in the combined population. Conclusion: Our data and the meta-analysis findings provide evidence that apolipoprotein E gene polymorphism has no direct significant association with hypertension.

Objective To investigate the clinical efficacy and safety between laparoscopic and transabdomi -nal hysterectomy ,reduce the occurrence of complications measures .Methods On 154 cases of hysterectomy indica-tions were nonrandomly divided into two groups ,one group for the observation group of 79 cases of laparoscopic opera-tion,another group was control group of 75 patients with transabdominal operation;two groups had no significant differ-ence in age and disease .The clinical effect ,postoperative complications and safety between the two groups during and after operations were observed .Results The operation time of the laparoscopic group (72.0 ±13.2) min was signifi-cantly shorter than that of the control group (98.0 ±20.7)min (t=3.396,P=0.021);The bleeding quantity of the laparoscopic group(96.0 ±75.4)mL was significantly shorter than that of the control group (159.4 ±98.0)mL(t=9.680,P=0.014);The aerofluxus time of the laparoscopic group (17.2 ±4.2) h was significantly shorter than that of the control group(28.6 ±6.1)h(t=9.760,P=0.013).The average postoperative hospital stay time was significantly shorter in laparoscopic group(5.2 ±1.9)d than those in abdominal group(9.5 ±3.2)d (t=-5.025,P=0.018). The analgesic used in the laparoscopic group (3/89)was significantly shorter than that in the control group (48/78) (t=-8.820,P=0.000).Conclusion Laparoscopic hysterectomy is safe and effective .It is worth to promote in clinical,while improving the operation skills is the key to reduce the complications .

Objective To investigate the feasibility,technique and clinical significance of preserving the great auricular nerve in parotid benign tumors surgery during the first postoperative year.Methods Fifty-two patients with parotid benign tumors were randomly divded into 2 groups.24 patients (group sacrificed) underwent classic parotidectomy with sacrifice of the great auricular nerve.The surgeons spare the nerve in the 32 patients with FOCUS ultrasonic harmonic scalpel (group preserved).Results After surgery,both groups showed lower levels of subjective sensation and sensory function test at auricle.These alterations were less pronounced in group preserved.Both groups showed improvement over time.In group preserved the sensory function reached normal level by 12 months after surgery.The recuperation in group sacrificed was partial at 12 months after operation.Conclusion The great auricular nerve preservation during parotidectomy is feasible,It can decrease sensory disturbance in the early postoperative period and avoid the permanent sequelae that occur when the nerve is sacrificed.The FOCUS ultrasonic harmonic scalpel technique can reduce the operation time.

Background and purpose:The extent of lymph node dissection for the stageⅢ lower rectal cancer is still a subject of debate. Some Japanese researchers recommend improved lateral lymph node dissection for stageⅢ lower rectal cancers while American scholars claim that total mesorectal excision is sufficient. This study aimed to explore the clinical significance of improved lateral lymph node dissection for stageⅢ lower rectal cancer in patients treated with radical resection.Methods:Sixty-six patients with stageⅢ lower rectal cancer were enrolled. Among these patients, 31 had been treated with radical resection combined with improved lateral lymph node dissection, whereas the others received radical resection without improved lateral lymph node dissection.Results:In the group of improved lateral lymph node dissection, five patients had positive lateral node including four poorly differentiated adenocarcinoma and one mucinous cell carcinoma. Compared with the group without improved lateral lymph node dissection, the group of improved lateral lymph node dissection showed significant difference in sexual disturbance, dysuresia and operation duration (P<0.05), but not in the presence of anastomotic fistula and blood loss during operation (P>0.05). Furthermore, patients had lower rate of pelvis recurrence and better 5-year rate of survival for the group of improved lateral lymph node dissection (P<0.05).Conclusion:Radical resection with improved lateral lymph node dissection may decrease the pelvis recurrence rate and increase survival rate in patients with stageⅢ lower rectal carcinoma.
