Objective To evaluate the advantages and disadvantages of different puncture positions in percutaneous nephrolithotomy. Methods Three hundred fifty-six patients who underwent PCNL were analyzed from March 2012 to October 2015. The passage caliber was 16F-20F. There were 217 cases in prone position and 139 cases in supine position. Results The successful operation in PCNL was 354 cases , while the remaining 2 cases were performed by open surgery. The primary stone clearance rate was 75.5%. The additional PCNLs were performed in 23 cases, and 63 cases of residual calculi were treated by ESWL. 11 patients were treated due to infection or bleeding by the additional PCNLs. There were 3 cases with massive hemorrhage which were treated by Interventional embolization therapy , 12 cases in postoperative fever , no renal resection , no intestinal injury, no deaths. There was no significant difference in stone clearance rate and complication rate between the two groups. Conclusion The puncture position of PCNL can be optional based on the stone size , stone location, degree of hydronephrosis ,and patient′s cardiopulmonary condition individually.

Objective To study the image examination of renal injuries and discuss renal explorative indications so as to spare the kidney or nephron as much as possible and improve curative rate of diagnosis and treatment. Methods An analysis was done on 286 cases that included 231 cases with close injury, 54 with open injuries, one with iatrogenic injury and 91 with combined injuries. Of all, 212 cases were examined by B-ultrasonography, 163 by CT and 132 by intravenous urography(IVU) and 6 by digital subtraction angiography(DSA); 202 cases were treated with conservative treatment and 84 with operation. Results The diagnostic positive rates of IVU, B-ultrasonography and CT were 67.4%, 72.2% and 87.7%, respectively. Among the operation cases, 42 cases were treated by renal repair, 12 by partial nephrectomy and 30 by nephrectomy. The operation rate was 29.4% and the nephrectomy rate 35.5%. Interventional treatment of the kidney was carried out in three cases. Conclusions For renal injury cases, the first and most important step is to evaluate the injury condition so as to correctly determine whether an operation exploration is needed. The injury conditions and severity are mainly determined by the image examinations that change according to injury cause, injury type and clinical symptoms. Renal exploration or not, and the operation time exert great influence on renal reservation rate and complication rate.

AlM:To explore treatment efficacy of the lower eyelid twitch muscle transposition surgery in senile entropion.METHODS:Fifty cases (86 eyes) of senile lower eyelid entropion patients underwent lower eyelid twitch muscle transposition correction surgery as the experimental group, and the other 42 cases (68 eyes) of senile lower eyelid entropion patients received orbicularis muscle shortening correction as controls group. The correction rate, double eyelid symmetry and overcorrection rate of patients were observed one week after surgery. The patients were followed up for 6~12mo to be observed the long-term recurrence rate, double eyelid symmetry and overcorrection rate.RESULTS: One week after operation, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05); After followed up for 6 ~12mo, eyelid symmetry, overcorrection rate of experimental group and control group had significant difference (P<0. 05). CONCLUSlON: Folding and orbicularis muscle shortening treatment of senile entropion was compared with the lower eyelid twitch muscle transposition surgery treatment of senile entropion, We can find that clinical results in double eyelid surgery symmetry and overcorrection rate are of obvious advantage.

Objective:The effect of antiviral therapy for hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after radical hepatectomy was assessed. Methods:A total of 478 HBV-HCC patients treated by radical hepatectomy were retrospectively col-lected. Patients in the treatment group (n=141) received postoperative lamivudine therapy (100 mg/d), whereas patients in the control group (n=337) did not. Recurrence-free survival rates, overall survival rates, treatments for recurrent HCC and cause of death were com-pared between the two groups. Propensity score matching was also conducted to reduce confounding bias between the groups. Results:The one-, three-, and five-year recurrence-free survival rates didn't significantly differ between the two groups (P=0.778);however, the one-, three-, and five-year overall survival rates in the treatment group were significantly higher than those in the control group (P=0.002). Similar results were observed in the matched data. Subgroup analysis showed that antiviral treatment conferred a significant sur-vival benefit for Barcelona Clinical Liver Cancer stage A/B patients. Following HCC recurrence, more people in the treatment group were able to choose curative treatments than those in the control group (P=0.031). For cause of death, fewer people in the treatment group died of liver failure than those in the control group (P=0.041). Conclusion:Postoperative antiviral therapy increases chances of receiving curative treatments for recurrent HCC and prevents death because of liver failure, thereby significantly prolonging overall sur-vival, especially in early-or intermedian-stage tumors.

OBJECTIVE: To evaluate the effect of aerobic exercise on genome expression in human skeletal muscle. METHODS: Six healthy sedentary elderly men aged (66+9) years were selected from military cadre retirement centers and after exercise. Testing indices included height, weight, vital capacity, step index and maximal oxygen uptake. Needle biopsies were obtained from the skeletal muscle before and after the last training. Total RNA extracted from the samples was hybridized to Affymetrix U 133A platform, the gene expression datum was analyzed.RESULTS: Aerobic exercise was shown to improve cardiorespiratory function and reduce body fat of elder subjects. It could alter the genome expression in human skeletal muscle, the number of genes that passed filtering criteria was 725. The most differently expressed genes (n=20) were investigated in this study, in which there were 3 upregulated and 17 downregulated. According to gene function annotations, the differential genes were classified into 8 categories which concerned cellular component and biological process, Kyoto Encyclopedia of Genes and Genomes (KEGG) searching showed 4 genes' metabolism pathway. CONCLUSION: Systematic aerobic exercise upregulates expression of enzyme genes concerning tricarboxylic acid cycle, and downregulates expression of genes conceming muscle protein synthesis and sphingolipid. It is suggested that aerobic exercise is good to protect human nerves' integrity, exerts positive action on anti-aging and accelerate the aerobic metabolism of lipid materials in vivo.

BACKGROUND: It has been proved that the application of basic fibroblast growth factor (bFGF) combined with Brucea Javanica oil emulsion can accelerate wound healing and inhibit scar formation.OBJECTIVE: To observe the effects of bFGF plus Brucea Javanica oil emulsion cream on accelerating the skin wound healing of rabbits.DESIGN: A randomized controlled observation.SETTING: Center of Biotechnological Research and Development, Jinan University; College of Pharmacy, Jinan University.MATERIALS:The experiment was carried out in the College of Pharmacy, Jinan University from June to September in 2004. Eight Beijing big-ear white rabbits (4 males and 4 females) of 2.0-2.5 kg were provided by the experimental animal center of Southern Medical University (certification number: SoKx-2002-010). bFGF sterile freeze dried powder agent,provided by Guangzhou Changsheng Gene Pharmaceutical Co.,Ltd (batch number: 20040219; specific activity was 6 000 U/bottle), was prepared to solution with water for injection before application. Brucea Javanica oil emulsion (manufactured by Zhejiang 999 Bang'erkang Pharmaceutical Co.,Ltd.) was provided by Professor Yao from staff Room of Pharmacy, Shenyang Pharmaceutical University.METHODS: The rabbits were anesthetized and disinfected, 5 round wounds with diameter of 1.8 cm and area of 2.54 cm2were induced from front to back by bilateral incision at 1.5 cm from middle spine of rabbit. The 5 wounds of each rabbit were randomly divided into bFGF-treated group (90 U/cm2), bFGF+Brucea Javanica oil emulsion group [the wound was smeared with Brucea Javanica oil emulsion (30 mg/cm2) 30 minutes after bFGF (90 U/cm2)], Brucea Javanica oil emulsion treated group [the wound was smeared with Brucea Javanica oil emulsion (30 mg/cm2)], blank emulsion group (30 mg/cm2) and blank control group (the wound was smeared with saline). The medication was give immediately after injury, and changed once a day for 16 days. At 4, 8, 12 and 16 days after injury, the wound areas were recorded with the method of hyaline membrane tracing (the wound was covered with clean saran wrap, the size of wound was traced,and then sheared to be weighed, and converted to calculate the area), and the volume of wounded cavity was measured by infusing water. At 8 and 16 days, the wound tissue was removed, stained after routine tissue sections, and the conditions of growth of granulation tissue and reepithelization on the wound surface were observed.MAIN OUTCOME MEASURE: The wound area, volume of wounded cavity, and the conditions of growth of granulation tissue and reepithelization on the wound surface were obviously at different time points after injury in each group.RESULTS:All the 8 rabbits were involved in the analysis of results. ① Wound areas at different time points in each group: The wound areas in the bFGF+Brucea Javanica oil emulsion group at 4, 8 and 12 days after medication were smaller than those in the blank control group at corresponding time points [(2.05±0.35), (1.59±0.25), (0.55±0.25) cm2;(2.53±0.30), (2.41±0.19), (1.09±0.34) cm2, P＜0.05-0.01]. The wound areas in the bFGF group at 8 and 12 days after medication were (1.71±0.31) and (0.51±0.10) cm2, which were significantly smaller than those in the blank control group at corresponding time points (P＜0.05-0.01). ② Volume of the wounded cavity in each group: The wound volume in the bFGF group at 4 days after injury was markedly smaller than that in the blank control group at corresponding time point [(0.49±0.12), (0.59±0.1) mL, P＜0.05]. The wound volumes in the bFGF+Brucea Javanica oil emulsion group at 4 and 8days after injury were significantly smaller than those in the blank control group at corresponding time points [(0.47±0.12), (0.30±0.08) mL; (0.59±0.1), (0.41±0.07) mL, P＜0.05, 0.01]. ③ Growth of granulation tissue and reepithelization on the wound surface in each group: At 8 days after injury, the inflammatory reaction was milder and fibroblasts proliferated significantly in the bFGF+Brucea Javanica oil emulsion group, and the numbers of capillary plumules and fibroblasts were significantly more than those in the blank control group. The conditions in the blank control group and blank emulsion group were generally the same that there were severe inflammatory reactions, obvious increase of granulation tissue, fewer new capillaries, and unobvious proliferation of epidermic cells. At 16 days after injury, the contraction and reepithelization on the wound surface were obvious, and the new epithelia went towards the wound center rapidly in the bFGF+Brucea Javanica oil emulsion group.CONCLUSION : The application of Brucea Javanica oil emulsion plus bFGF can obviously accelerate the repair of incised wound on the back of rabbits.

OBJECTIVETo study intra-operative radionuclide lymphatic mapping in sentinel lymph node (SLN) biopsy of breast cancer.

METHODSForty-two breast cancer (diameter 98%, size of colloid granule 100 approximately 200 nm) was injected into the mammary tissue around the tumor or biopsy site at four points. SLN in breast cancer was detected and dissected with the help of lymphoscintigraphy and intra-operative gamma probe. Routine lymph node dissection was performed for all patients.

RESULTSThe detection rate was 88.1% in lymphoscintigraphy and 97.6% in intra-operative gamma probe detection for SLN in breast cancer. The sensitivity, accuracy, false negative and specificity of SLN biopsy were 93.3% (14 in 15), 97.6% (40 in 41), 6.7% (1 in 15) and 100% (26 in 26).

CONCLUSIONSentinel lymph node in breast cancer, detected by preoperative lymphoscintigraphy combined with intra-operative gamma probe, is able to predict regional lymph node metastasis. The successful rate of SLN biopsy can be raised by improvement in the quality of nuclear imaging agent, technic of injection and method of measurement.
