Hereditary angioneurotic laryngeal edema (HALE) is an autosomal dominant hereditary disease in which there is a decrease or defect in the C1 inhibitor (C1-INH). The pathophysiology of HALE is characterized by recurrent spontaneous episodes of transient edema of the laryngeal mucose and submucosal tissue with remission at irregular. Patients may die because of a life-threatening acute upper airway obstruction caused by laryngeal edema. HALE was diagnosed on the clinical symptoms, family history, and markedly decreased serum C1-INH activity and C1-INH protein.

Objective To explore the safety and effectiveness of transurethral resection of the prostate (TURP) for large benign prostatic hyperplasia.Methods A total of 56 cases of patients with large benign prostatic hyperplasia were analyzed retrospectively.Results The weight of prostate tissue resected with TURP was 60.2 g (48-122 g).The resection rate was 60％,operation time 113.4 min (70-180 min).The lower urinary tract symptoms (LUTS) after TURP was improved significantly.The international prostate symptom scores (IPSS) of 38 cases were decreased from (25.6±1.5) before operation to (6.0± 2.0) after operation.The maximum urine flow rate were increased from (5.0±1.9) ml/s to (18.0±4.5) ml/s.The mean residual urine volume of 22 cases were reduced from 95 ml (40-250 ml) to 10 ml (0-60 ml).Conclusions Skilled TURP technology for large benign prostatic hyperplasia is a safe treatment with good effect and low complications rates.

OBJECTIVETo study on the reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in total knee arthroplasty (TKA) the rotational alignment reference bony landmarks of the proximal tibial component on magnetic resonance image (MRI) were measured.

METHODSFrom January 2010 to December 2013, 80 normal knees of Chinese volunteers including 35 males and 45 females with an average age of (35.4±6.1) years were reviewed. The images of the knees were obtained by MRI. The surgical epicondylar axis (STEA) was identified in the femoral transverse sections and then was projected to the side of tibia, forming the SETA'. A line connecting the medial border of the patellar tendon and the middle of the posterior cruciate ligament insertion (Akagi line) and its vertical line (AK), as well as a line connecting the medial 1/3 of the patellar tendon and the middle of the posterior cruciate ligament insertion and its vertical line (AP), were identified in the tibial transverse sections. The angles were measured between the AK, AP and STEA'.

RESULTSThe angle between AK and STEA' was (0.59±2.07)°, and there was no significant difference between the two lines (t=-2.54, P=0.13). The mean angle between AP and STEA' was (3.21±2.04)°, and there was a significant difference between the two lines (t=14.05, P<0.05). There was a significant difference between the AK and AP (t=-11.68, P<0.05).

CONCLUSIONThe reliability of the Akagi line as a reference axis to guide for rotational alignment of the proximal tibial component in TKA is good.

Objective To explore the effect of electroacupuncture (EA) at tusanli (ST36) on regulation of stress response under different doses of etomidate anesthesia in rats.Methods Sixty male Sprague-Dawley rats, weighing 280-310 g, were randomly divided into control group (group C), model group (group M), etomidate 60 mg/kg group (group E1), etomidate 30 mg/kg group (group E2), etomidate 60 mg/kg combined with EA group (group EA1) and etomidate 30 mg/kg combined with EA group (group EA2), n=10 in each group.All groups received inferior caudal trunk transection at the level between sacral spinal nerve 3 and 4 (S3, S4) to prepare acute stress response model except group C.Group M received no others treatment.The rats in group E1, group EA1, group E2 and group EA2 were intraperitoneally injected with 60, 60, 30 and 30 mg/kg etomidate, respectively.Group EA1 and group EA2 received EA ST36.The points were stimulated at a frequency of 2/100 Hz with 1 mA output and a dilatational wave, which lasted for 30 min.ACTH and Cor levels were measured by ELISA.The c-fos protein expression in hypothalamic tissue was examined by Western blot.Results Compared with group C, ACTH and Cor levels, and hypothalamic expression of c-fos protein in group M were significantly increased (P<0.05).Compared with group M, serum ACTH and Cor levels, and hypothalamic expression of c-fos protein in groups E1, E2, EA1 and EA2 were significantly decreased (P<0.05).Compared with group E1, serum ACTH and Cor levels, and hypothalamic expression of c-fos protein were significantly higher in groups E2 and EA1 (P<0.05).Compared with group E2, serum ACTH level and hypothalamic expression of c-fos protein were significantly lower in group EA2 (P<0.05).Conclusion EA at ST36 regulating stress response under etomidate anesthesia in rats is effective and two-way, and the mechanism may be due to the release of neurotransmitters induced c-fos protein in hypothalamus.

OBJECTIVE:To compare the efficacy,safety,vascular endothelial growth factor(VEGF)and matrix metallopro-teinase-2 (MMP-2) of docetaxel combined with carboplatin and paclitaxel combined with cisplatin (DDP) in the treatment of ad-vanced ovarian cancer. METHODS:120 patients with advanced ovarian cancer were randomly divided into docetaxel combined with carboplatin group(60 cases)and paclitaxel combined with DDP group(60 cases). Docetaxel combined with carboplatin group received 70 mg/m2 Docetaxel injection,intravenous infusion of 1 h,d1;50 mg/m2 carboplatin injection,intravenous infusion of 1 h,d2. Paclitaxel combined with DDP group received 135 mg/m2 Paclitaxel injection,intravenous infusion of 24 h,d1;30 mg/m2 DDP for injection,intravenous infusion,d3;60 mg/m2 Paclitaxel injection (a maximum of 2.0 m2) by intraperitoneal infusion,d8. 3-week was regarded as 1 treatment course,and it lasted 6 courses. Clinical efficacy,VEGF,MMP-2,progression-free survival, overall survival before and after treatment,mortality rate within 2 years of treatment and the incidence of adverse reactions in 2 groups were compared. RESULTS:There were no significant differences in the objective response rate,disease control rate,mortal-ity rate,incidence of adverse reactions between 2 groups(P>0.05). The progression-free survival in docetaxel combined with car-boplatin group was significantly longer than paclitaxel combined with DDP group,the difference was statistically significant (P<0.05). Before treatment,there were no significant differences in VEGF and MMP-2 level between 2 groups(P>0.05). After treat-ment,VEGF and MMP-2 level in 2 groups were significantly lower than before,and VEGF at different time points and MMP-2 level after 4 weeks,8 weeks and 12 weeks of treatment in docetaxel combined with carboplatin group were lower than paclitaxel combined with DDP group,the differences were statistically significant(P<0.05). CONCLUSIONS:Docetaxel combined with car-boplatin and paclitaxel combined with DDP shows similar efficacy and safety in the treatment of advanced ovarian cancer,but docetaxel carboplatin combined with is superior to paclitaxel combined with DDP in reducing VEGF and MMP-2 and improving pro-gression-free survival.

Objective To evaluate the efficacy of percutaneous transluminal angioplasty (PTA) in the treatment of transplanted renal artery stenosis (TRAS)-induced renal dysfunction and hypertension. Methods Between July 1998 and January 2007, PTA was performed on 16 patients with RTAS. Color Doppler uhrasonography preceded the intra-arterial angiographic investigation,with false-negative results in 18. 75 % of patients. Sixteen cases of TRAS were examined at 1 st week,6th month and 13 years after PTA. Hypertension improvement was defined as mean arterial pressure decrease of at least 15 % from the pre-PTA value. Graft function was evaluated by SCr levels, and the improvement was defined as a 20% change. Results Angioplasty was technically feasible in 100 %.Sixteen patients with RTAS were cured clinically. During the follow-up period, graft function was improved in 81.25 %, 68. 75 %, 62. 5 %, 56. 25 %, 50 % of patients respectively at 1st week, 6th month and 1-3 years after PTA. The blood pressure was decreased in 62. 5%, 75 %, 75 %,56. 25 %, 50 % of patients respectively, but no patient remained hypotensor medication free.Conclusion PTA improved renal dysfunction and hypertension induced by TRAS, and it is a safe and effective treatment for TRAS.

To explore the new method of discriminating Cistanche deserticola, Cynomorium songaricum and Orobanche pycnostachya by using PCR amplification of specific alleles. 30 samples of the different C. deserticola, 21 samples of C. songaricum and O. pycnostachya were collected. The total DNA of the samples were extracted, the ITS sequences from C. deserticola, C. songaricum and O. pycnostachya were amplified by PCR and sequenced unidirectionally.
