Objective To investigate the effects of the traditional herb-epimedium on the expression of interleukin-6 (IL-6) mRNA in bone of ovariectomized rat. Methods Forty female rats were randomly allocated into 4 groups, 10 in each: ovariectomized (OVX) group, sham operation group, OVX followed by epimedium (group 3)or nilestriol (group 4) for 3 months respectively. All rats were then sacrificed,and total RNA were directly isolated from their right tibia. Interleukin-6 mRNA expression was detected by relative semiquantitative reverse transcription-polymerase chain reaction technique. Lumbar bone mineral density (BMD) was measured by dual-energy X ray absorptiometry before sacrifice. Results The BMD of epimedium group was significantly higher than that in the OVX group ( P

Objective To observe the influence of early postoperative feeding in the healing of intestinal anastomosis in rabbits,and to clarify preliminarily the relationships between early postoperative feeding after gastrointestinal surgery and gastrointestinal anastomotic fistula formation and healing time in rabbits.Methods 48 rabbits were randomly divided into experimental group and control group, then they were treated with gastrointestinal anastomosis.The rabbits in experimental group were fed with liquid diet 24 h after operation,and the rabbits in control group were fed nothing after operation and supplied by total parenteral nutrition.Two rabbits of each group were selected for exploratory laparotomy on the 3rd,5th,7th,10th and 15th day after operation,and the healing rate of anastomosis,the anastomotic bursting pressure,the anastomotic breaking strength,and the hychoxyproline level of anastomosis were observed.Results The healing rate of anastomosis in control group was 91.6%(22/24), and the healing rate of anastomosis in experimental group was 95.8%(23/24),there was no significant difference between two groups(P>0.05).The anastomotic bursting pressures of the rabbits in two groups were decreased remarkably at the 72nd hour after operation,which was the lowest point,and they were increased remarkably on the 5th day after operation,but the anastomic bursting pressure in experimental group was a little lower than that in control group,and it reached the peak on the 7th day after operation in control group. On the 10th day after operation,the anastomic bursting pressure in control group was a little lower than that on the 7th day after operation,but the anastomic bursting pressure in experimental group reached the peak.There were no significant differences of anastomic bursting pressure at different time points between two groups(P>0.05).The anastomotic breaking strength had no significant difference between two groups at the 72nd hour after operation,both of them reached the lowest points,however the anastomtic breaking strengths in two groups were increased remarkably on the 10th day after operation,and reached the peaks.but there were no significant differences of anastomic breaking strength at different time points between two groups (P>0.05 ). The hychoxyproline level of anastomosis:in experimental group was a little lower than that in control group at the 72tnd hour after operation,and both of them reached the peaks on the 7th day after operation;but there were no significant differences of hychoxyproline levels of anastomosis at different time points between two groups(P>0.05).Conclusion Early postoperative feeding can not cause the increase of anasmotic healing time and the incidence rate of gastrointestinal anastomotic fistula.

Self-adaptive interference canceller based on LMS algorithm is an excellent filter which can adjust system parameter automatically. With good robustness, it can be applied to every signal abstraction and data treatment, especially bioelectric signals. By this algorithm, both the power frequency interference and baseline shift, for example, the ones of ECG signals, can be successfully eliminated.

A number of reports have appeared implicating neurotoxicity of local anesthetics as a possible cause of neurologic complications after spinal anesthesia. Transient neurologic syndrome is one of neurologic complications. This article reviews the etiology, occurred mechanism, clinical symptoms, risk factors, prevention and treatment of transient neurologic syndrome.

Objective To study the safety over the atlanto-odontoid joint of the cervical spine during oblique-pulling manipulation.Methods The contact stress of the atlanto-odontoid joint in physiologic unstable conditions with and without pulling-and-extending of seven cadaveric specimans of cervical spine were observed with a biomechanical electric measuring apparatus and oblique-pulling device.Results The ratio of contact stress in pulling-and-extending condition,physiologic condition and pathologic condition is 1∶1.2∶9.4.Under normal physiologic condition,the stress in posterior extension is greater than that in anterior flexion,but less than in neutral position.Conclusion A better option of the manipulation position is to put the patient′s head at a slight flexion when a certain pulling-extending force is applied.In patient with severe degenerative changes of the cervical spine and unstability,the amplitude of rotation and the force of manipulation should be decreased.

ObjectiveTo investigate the value of MRI in the diagnosis of cavernous transformation of the portal vein (CTPV).MethodsPlain MRI,dynamic enhanced and (or) dynamic contrast enhanced magnetic resonance angiography(DCE-MRA) findings in 30 patients of clinical-proved CTPV were retrospectively analyzed.ResultsAmong 30 CTPV patients on plain MRI,obliteration of main and (or) branched portal vein were found,and mass-like or reticular abnormal soft-tissue signals were around the vein,which were produced by collateral vessels.On dynamic enhanced MRI,abnormal hepatic perfusion during arterial phase and abnormal enhanced collateral veins during portal phase could be seen.The above signs became more obvious on DCE-MRA.ConclusionsMRI and DCE-MRA can clearly visualize the anatomical features of CTPV.It is important and can provide the reliable evidence for planning properly therapeutic protocol to recognize and directly evaluate the CTPV.

Objective To explore the clinical and histopathological features of metanephric adenoma (MA). MethodsClinical and pathological data of 10 cases of MA were analyzed retrospectively.There were 4 males and 6 females,aged from 33 to 65 years,with an average of 45 years.2 patients had flank pain,4 patients had gross hematuria,and 4 patients were found by physical examination.The average diameter of tumor was 4.5 cm (2.5 - 8.0 cm).All patients were diagnosed as renal tumor by CT scan.9 patients underwent radical nephrectomy and 1 patient underwent partial nephrectomy. Results Pathological examination found that the tumors are composed of densely packed small uniform cells with regular nuclei that formed a tubular or adenoid pattern.Mitotic figures were absent or rare.4 patients were diagnosed as MA,2 cases were diagnosed as low-grade malignant MA,and 4 cases were diagnosed as MA with malignant component (2 cases of adenocarcinoma,1 case of chromophobe cell carcinoma,and 1 case of well differentiated papillary adenocarcinoma),7 cases were followed up for 22 months ( 10 to 34 months) without recurrence or metastasis. Conclusions MA is very rare benign renal tumor originating from epithelium,and a few are malignant,and some may contain malignant ingredients.Nephron-sparing surgery and radical nephrectomy are eligible for the treatment of MA.Considering the uncertainty of the biological behavior and cellular origin of MA,a long-term follow-up is necessary.

OBJECTIVETo compare the efficacy on vertebrobasilar insufficiency (VBI) between auricular acupuncture therapy and oral administration of medicine.

METHODSSixty patients of VBI were randomized into an auricular acupuncture therapy group and a medicine group, 30 cases in each one. In the auricular acupuncture group, acupuncture was applied bilaterally to gan (CO12) and jiejie (HX8) on the ears and needles were retained for 15 min. After needle withdrawal, the vaccariae semen were fixed with plaster at naogan (AT3, 4i), zhen (AT3), jing (AH12), shen (CO10) and pi (CO13) on the ears. In the medicine group, flunarizine hydrochloride capsules (Sibelium), 5mg were prescribed for oral administration, once every night. The treatment lasted continuously for 2 weeks (14 days) in the two groups. In 2 weeks, the clinical efficacy was assessed and the transcranial doppler (TCD) examination was performed.

RESULTSAfter treatment, the symptom scores were all apparently reduced in the patients of the two groups (P < 0.01, P < 0.05). Compared with the medicine group, the reduced score was much more obvious in the auricular acupuncture group (P < 0.05), indicating the significant difference. After treatment, with TCD examination, the blood velocity was increased to different degrees in the patients of low velocity type in the auricular acupuncture group and the medicine group; that was reduced to different degrees in the patients of high velocity type in the auricular acupuncture group and the medicine group. All of them were different significantly as compared with those before treatment (all P < 0.05). But the difference was not significant between the two groups (both P > 0.05). In comparison of clinical efficacy between the two groups, the effective rate was 93.3% (28/30) in the acupuncture group and better than 76.7% (23/30) in the medicine group, indicating the significant difference in comparison (P < 0.05).

CONCLUSIONThe auricular acupuncture therapy achieves the definite efficacy on VBI and the efficacy is better than flunarizine hydrochloride capsules.

The role of autophagy is known to be highly complex and context-dependent, and may be characterized as both tumor suppression and tumor promotion in some tumors, such as breast cancer and prostate cancer. This review outlines recent advances in the studies of the involvement of autophagy in the development, progression and treatment of prostate cancer, focusing on autophagy modulation during androgen deprivation, with a special discussion on the regulatory effect of androgens on the autophagy of prostate cancer cells. A critical evaluation and analysis of the studies suggests that autophagy inhibition combined with androgen deprivation therapy is a promising approach to the treatment of prostate cancer.
