Objective To study the relationship between urinary heparin and human bladder transitional cell carcinoma(BTCC) Methods Reverse polarity capillary electrophonesis(RPCE)in a phosphate buffer was used to determine the value of urinary heparin in 19 patients with BTCC and in 9 normal individuals. Results The value of urinary heparin was (2.37?1.06)?g/L in 9 normal subjects,(1.11?0.45)?g/L in 9 patients with Ta～T 1 BTCC and (0.41?0.13)?g/L in 10 patients with T 2～T 4 BTCC. Conclusions Falling of urinary heparin in BTCC plays an important role in the occurrence and invasiveness of BTCC.

Objective To study the diagnosis accuracy and the treatment sequelae of adenocarcinoma of urinary bladder. Methods 41 cases of urinary bladder adenocarcinoma have been encountered from 1980 to 2000,all of them had undergone operation and the diagnosis being assessed on histopathology studies.There are 18 cases of primary bladder adenocarcinoma,among which 8 had undergone radical cystectomy and 10 partial cystectomy.Among 12 cases of urachal adenocarcinoma extending to the bladder,11 received extended resection.All the 11 patitents with metastatic focus in the bladder underwent local ablation. Results Urinary bladder adenocarcinoma comprised 3.2% of the bladder cancer.Thirty seven patients have been followed up for five months to ten years.The 1 year survival rate was 51.3%(19 cases),the 2 year survival rate 43.2%(16 cases) and the 5 year survival rate 21.6%(8 cases). Conclusions Radical total cystectomy is the treatment of choice for primary adenocarcinoma of bladder and extended partial cystectomy seems to be the best for urachal adenocarcinoma. Comprehension therapy should be undertaken for patients with metastatic adenocarcinoma or tumor recurrence so as to improve the survival rate.

Objective To investigate the effects of 860MHz microwave on the formation and extinction of context conditioned fear in mice. Methods The mice were exposed to 860MHz continuous microwave ( power density were 380 μW/cm2 or 550 μW/cm2, respectively) for 30 min or 2 h, which then were divided in to 5 groups.Each group consisted of 15 animals. Footshocks were used to induce context conditioned fear by 75 voltages. The frequency and time of freezing after irradiation were investigated. Results When 24 h after foot shocking, the values of freezing time: control group was 2.31 ±4. 17 , two groups of the microwave irradiation 2 h were 3.93 ±6.99 and 2.47 ± 3.34, the Nemenyi test results (P = 0.004): control group was 32.63333, while two groups of the microwave irradiation 2 h were 52.46667 and 39.76667; and the values of freezing frequency: control group was 0.73 ± 1.16 , two groups of the microwave irradiation 2 h were 0.86 ± 1.41 and 1.07 ± 1.16, the Nemenyi test results of (P=0. 014): control group was 33. 26667, while two groups of the microwave irradiation 2 h were 50. 76667 and 40.90000. Conclusion The mice receiving relatively longer period of microwave irradiation showed more stable memory of the context conditioned fear.

Objective:To study the expression and significance of cyclinD 1 in 45 cases of transitional cell carcinoma of bladder.Methods:The expression of cyclinD 1 was detectde by immunohistochemistry(SP).Results: Expression of cyclinD 1 was found in 55.56% of TCCs and none of controls,and 78.57% of T a～T 1,11.76%of T 2～T 4.Approximately,85% of G 1,46.67% of G 2 and 10% of G 3 with the progress of tumors clinical stages and grades ,and the positive rates of cyclinD 1 expression decreased. There was no significant correlation between cyclinD 1 expression and number of lesions and postoperative reccurance.Conclusions: CyclinD 1 overexpression can play an important role in the early stage of bladder tumorgenesis.There was significant relativity between cyclinD 1 expression and the biological behaviour of bladder TCCs.

Objective To evaluate the occurrence of antiandrogen withdrawal syndrome in patients with advanced prostate cancer treated with combined androgen blockade. Methods 24 cases of advanced prostate cancer (10 in stage C and 14 in stage D) were retrospectively studied. All the patients have been treated with combined androgen blockade (bilateral orchiectomy and flutamide). After initial beneficial response to hormonal therapy (duration 7 to 36 months), the disease became progressing.Flutamide was then discontinued. Serum prostate specific antigen (PSA) levels and symptoms alterations were observed. Results Following withdrawal of flutamide, 8 patients showed a decline in PSA (mean 75%).In 6 the PSA declined more than 50%. Clinical symptoms improved in 4 patients and the prostate mass became smaller in 2. The mean duration of improvement was 4.3 months. Conclusions In patients with hormone refractory prostate cancer after initial combined androgen blockade, a trial of "antiandrogen withdrawal" is a reasonable therapeutic management prior to other more toxic therapies.

Objective To evaluate the modified Stamey bladder neck suspension for female stress urinary incontinence. Methods 52 cases with an average age of 46 and an average stress incontinence history of 7.5 years underwent the modified Stamey procedure,18 cases being degree Ⅰ,21 degree Ⅱ and the other 13 degree Ⅲ. Results 32 cases were treated before 1994 and the outcome was evaluate at 3.6 years and 9.6 years postoperatively.There were 3 failures because of operative complication.The cure rates and failure rates at 3.6 and 9.6 years were 87.5%,68.8% and 6.2%, 21.9%,respectively.20 cases were treated after 1994 with a follow up of 4.3 years.The cure rate has been 90.0%. Conclusions The Stamey procedure yields high initial cure rates yet the latter declines with time.

Objective To study the synthesizing site,transporting mode,and storing position of essential oil in Pogostemon cablin stems and leaves.Methods Ultrathin slicing and histochemical methods were used.Results In parenchyma cells in the stem of P.cablin,dark osmiophilic material was observed in plastids and mitochondria,otherwise,some small gray vesicles were also found in cytoplasm.Some dark osmiophilic droplets were found to adhere to outer membrane of small gray vesicles,and many small gray vesicles with osmiophilic droplets gathered in outer membrane of large vacuole.In leaves,it was different case.Because palisade tissue cells were arranged closely,which had smaller volume and rich chloroplasts,so there was not large vacuole in palisade tissue cells.Plastids,mitochondria,and small vacuole were distributed in high density,but the first two organelles contained more dark osmilphilic substance than latter.Conclusion The plastid is the main synthesis site of essential oil,and the essential oil was mainly transferred by small gray vesicles into large vacuole to store in the stem.In leaves,chloroplast not only has photosynthesis,but also is the main synthesis site of essential oil,and essential oil is permeated into small vacuole to store.

Objective To investigate clinical service delivered at the Polyclinic of Beijing 2008 Olympic and Paralympic Village and outcomes of the medical patients visited there.to provide experiences in medical care service for other mass-gatherings in the future.Methads Clinical data of all the medical patients evaluated at the Polyclinic during July 27 to August 27 and during August 29 to September 19,2008 were reviewed retrospectively.with univariate and multivariate analyses.Results In total.1537 and 1206 medical patients visited the Polyclinic at the Olympic and Paralympic Village,respectively.Proportion of athletes visited was hisher during the Paralympic Games than that during the Olympic Games(14.2% vs.9.8%,P<0.01).We reeeived 775 patients(50.4%)with acute respiratory tract disorders,including 16 cases(1.0%)with asthma,during the Olympic Games,and 686(56.9%),including eight cases (0.7%)with asthma,during the Paralympic Games,and antibiotics were prescribed for 149(9.7%)and162(13.4%)of them,respectively.Twelve(0.8%)patients were hospitalized during the Olympic Games and four(0.3%)during the Paralyrnpie Games,and age equal to or nlore than 55 years and digestive disease were independent risk factors for hospitalization,with odds ratios(ORs) of 5.3 and 9.5 and their 95% confidence intervals(Cls)of 1.4-19.6 and 2.5-36.4,respectively.Conclusions Acute respiratory disorder was the most connnon cause for medical visits in the Polyclinic.Asthma did not play a significant role to iniluence athletes'performance in the Beijing 2008 Olympic and Paralympic Games.Antibiotic prescription in the Polyclinic had been controled to an acceptable level.Conditions in elder patients and those with digestive disorder tended to be severe.deserving more attention infuture's mass gathering.

Objective To approach the design and clinical application of large anterolateral thigh flap and its effect in wound repair.Methods The flaps were designed according to the anatomical features of perforating branches in the anterolateral thigh flaps.When a flap was chipped,a thick branch or a terminal branch of original vessel was reserved,another suitable perforating branch was selected in the proximal or distal end of the flap,and then the two vessels were anastomosed to enlarge the range of blood supply.If the vessel pedicle of a flap was a musculocutaneous perforating branch,the perforating branch of anastomosis was cut at out-point of muscle.If the vessel pedicle of a flap was a intermusclar branch or a direct skin artery,the perforating branch of anastomosis was cut widely.From May 2006 to May 2012,the technique was applied in 28 patients with large skin defect of limbs.The diameters of perforating branches obtained at out-point of muscles were measured during surgery.The survival of flaps was observed after surgery and complications in donor sites were checked during follow-ups.Results There were 18 flaps whose vessel pedicle were musculocutaneous perforating branches.The branches were cut at outpoint of muscles.The diameters of these vessels were measured during surgery.They ranged from 1.3 mm to 1.8 mm with an average of 1.45 mm.All of the vessels could be anastomosed.All 28 flaps survived.All flaps survived.The areas of the flaps ranged from 22 cm × 15 cm to 42 cm × 14 cm.Artery crisis happened in 2 flaps whose vessel pedicle were musculocutaneous perforating branches.The second look operation found that the areas of artery anastomosis of perforating branches and vessel pedicles were compressed by hematoma and thrombus formed.The 2 flaps survived after the hematoma was cleared away and the vessels were reanastomosed.There were no infections.Both the donor and recipient site healed by first intention with no necrosis of flap margin.All 28 patients were followed up by 4-13 months with an average of 8 months.There were no apparent collapse deformities,muscle necrosis,declines of muscle strength and muscle hernia in the donor sites.The appearance of flaps was flat,the color was close to normal and the quality was fine.Conclusion It is a safe and effective method to repair wound surface by large anaterolateral thigh flap obtained by the modus operandi of perforating branch anastomosis.

Expression of platelet-derived growth factor (PDGF)-B mRNA was measured by semi-quantitative RT-PCR in renal cortex of diabetic and control Wistar rats. The expression of PDGF-B mRNA in renal cortex of diabetic rats was 2.5-fold of normal rats, suggesting that PDGF-B seems to play a role in diabetic nephro-pathy.
