Objective To explore CT features of thin-wall cavity change of pulmonary metastases from renal clear cell carcinoma after molecular targeted treatment and its clinical significance.Methods Clinical and imaging data of 2 patients with thin-wall cavity of pulmonary metastases originating from renal clear cell carcinoma after molecular targeted drug Pazopanib were reported and analyzed retrospectively.Results After resection of primary renal tumors,multiple solid metastatic lesions in the lung were detected and the lesions showed ring enhancement on the post-contrast images.After 3-month Pazopanib treatment,most of the lesions presented thin-wall cavity change.Case 1 showed slowly disease progression while case 2 suffered from spontaneous pneumothorax and died 2 months later.Conclusion Necrosis of pulmonary metastases originated from renal carcinoma can be impelled by molecular targeted Pazopanib treatment,which helped to the formation of cystic thin-wall cavity,but the influence on the prognosis still remains uncertain.

Objective To investigate the antitumor effect of the recombined adeno-associated virus encoding caveolin-1 regulated by progression-elevated gene (PEG) promotor on the angiogenesis of implanted human hepatocellular carcinoma(HCC) cell lines in a nude mouse model. Methods HepG2 cells were inoculated subcutaneously into NOD/SCID mice, and animals were treated with rAAV-PEG-caveolin-1 after tumor cell innoculation. The fluorescence ratio of Evans blue to FITC-dextran was used to assess the changes of microvasculature permeability of the tumor. Western blot and immunohistochemical analyses were employed to detect PECAM-1 expression in tumor microvascular endothelium and microvessel density(MVD), respectively; NOS activity was assessed by citrulline generation. Tumor growth was observed and tumor cell apoptosis in tumor tissues were measured by TUNEL. Results Tumor growth was significantly inhibited in mice injected with rAAV-PEG-caveolin-1. The administration of rAAV-PEG-caveolin-1 significantly blocked vascular leakage in the tumor microcirculation. The levels of PECAM-1 protein detected by Western blot were markedly reduced in rAAV-PEG-caveolin-1-treated mice, and there were fewer MVD in tumors from caveolin-1-treated mice, while NOS catalytic activity was much lower in rAAV-PEG-caveolin-1-treated mice compared to the control and empty vector-treated animals. TUNEL demonstrated significant induction of tumor cell specific apoptosis. Conclusions rAAV-PEG-caveolin-1 can reduce tumor progression through blocking microvascular formation by inhibiting eNOS.

Objective To conduct research of β-Thalassemia incidence and genotypes on children below 7 years of age in Nanning, Liuzhou and Baise areas, Guangxi province. Methods A total of 2261 children aged below 7 in Nanning, Liuzhou and Baise areas were studied. Venous blood was detected by routine blood test, hemoglobin analysis and β-Thalassemia genotyping. Results Among 2261 samples, 125 showed high level of HbA2 and were diagnosed as β-Thalassemia (5.53%). Genotypes of the patients were classified as: 59 cases with β-globin gene eondon (CD) 41-42 mutation, 33 cases CD17 mutation, 18 cases with TA TA box nt-28 mutation, 7 with IVS-Ⅱ-654 mutation, 3 with CD43 mutation, 3 with HbE mutation, one with CD71-72 and TATA box nt-29 mutation, respectively. The genotyping frequencies of β-Thalassemia were as follows: 47.20% for CD41-42 mutation, 26.40% for CD17 mutation, 14.40% for TATAbox nt-28 mutation, 5.60% for IVS-Ⅱ -654 mutation, 2.40% for CD43 mutation, 2.40% for HbE mutation, 0.80% for CD71-72 mutation and TATAbox nt-29 mutation respectively. Conclusion This study on children in the area with high incidence of β-Thalassemia reflected the incidence and characteristics of genotypes in this area. Our data also provided evidence for the development of a program on genetic counseling and prevention for thalassemia.

OBJECTIVETo investigate the genetic causes of azoospermia and severe oligozoospermia.

METHODSCytogenetic analysis and multiplex polymerase chain reaction(PCR) analysis were done on the 148 patients with azoospermia and serious oligozoospermia.

RESULTSEleven of the 148(7.4%) cases showed microdeletion of at least one STS. In fifteen STS of AZFa, AZFb,AZFd, AZFc, thirteen STS, eleven STS,two STS and one STS microdeletion were found in each case respectively, including two with 12 STS, five with 5 STS microdeletion.Seven cases had chromosomal morphologic changes(4.7%),four had deletion and one had deletion with translocation of long arm on Y chromosome. One had enlarged region one band two(q12) on long arm of Y chromosome and one had reciprocal translocation of autosomes.

CONCLUSIONThe findings indicated that AZF microdeletion and chromosomal abnormality should be important causes of male infertility.

PURPOSE: Acute renal graft rejection can only be definitively diagnosed by renal biopsy. However, biopsies carry a risk of renal transplant injury and loss. Micro-CT is widely used in preclinical studies of small animals. Here, we propose micro-CT could noninvasively monitor and evaluate renal location and function in a mouse kidney transplant model. METHODS: Orthotopic kidney transplantation was performed in a BALB/c -to- C57BL/6j or C57BL/6j-to- C57BL/6j mouse model. After optimizing imaging techniques, five mice were imaged with micro-CT and the findings were verified histologically. RESULTS: Micro-CT can monitor and evaluate renal location and function after orthotopic kidney transplantation. There were no mice deaths while renal transplants were failure. CONCLUSION: We propose that graft micro-CT imaging is a new option that is noninvasive and specific, and can aid in early detection and follow-up of acute renal rejection. This method is potentially useful to improve posttransplant rejection monitoring.

BACKGROUND:Epidural analgesia has been considered a gold standard for postoperative analgesia in the lower limbs. Its outcomes are accurate and adverse reactions are few, so it can be used in the clinic. However, this method has adverse reactions such as hypotension and urine retention. Low molecular weight heparin should be used after operation, which can increase the possibility of epidural hematoma, and limits its application to epidural analgesia in the clinic. At present, few studies concerned ultrasound guided continuous fascia iliaca compartment block technology.
OBJECTIVE:To evaluate the efficacy of postoperative pain relief and the joint rehabilitation between a continuous fascia iliaca compartment block and a continuous epidural analgesia for patients undergoing total hip arthroplasty.
METHODS:A total of 60 patients undergoing a selective total hip arthroplasty were assigned to continuous fascia iliaca compartment block group and continuous epidural analgesia group (n=30). Al patients in both groups received a pre-fluence before general anesthesia. Continuous fascia iliaca compartment block group were injected with 0.25%ropivacaine 30 mL via iliac fascia gap. Continuous epidural analgesia group received 0.20%ropivacaine 10 mL via epidural catheter, indwel ing catheter. When the analgesic effect was identified, anesthesia intubation was carried out. After operation, medicine was given via iliac fascia and epidural analgesia pump in both groups respectively. Postoperative analgesia in single dose was not given. If pain could not be endured, analgesia would be rescued (parecoxib 20-40 mg/time) according to pain degree. Visual analogue scale scores, supplemental analgesia of parecoxib, complication of anesthesia, Harris hip joint scores, day of first walk, and duration of hospital stay were recorded.
RESULTS AND CONCLUSION:No significant difference in visual analogue scale scores, supplemental analgesia, Harris hip joint scores and duration of hospital stay was detected. Day of first walk was earlier in the continuous fascia iliaca compartment block group than in the continuous epidural analgesia group. The complications were apparently lower in the continuous fascia iliaca compartment block group than in the continuous epidural analgesia group. These data indicated that after total hip arthroplasty, two kinds of analgesia methods could provide satisfactory postoperative outcomes. Hip joint was perfectly recovered. However, the complications of continuous fascia iliaca compartment block were less, and helpful to patients’ early off-bed activities, and could be considered as a good choice for analgesia after total hip arthroplasty.
