Objective To evaluate the CT appearance of the hepatocellular carcinomas (HCC) supplied by the right inferior phrenic arteries (RIPA). Methods A total of 195 consecutive cases of HCCs examined with helical CT and arteriography were studied. 15 proven HCCs cases were supplied by the RIPA. On arterial phase CT images, the size of the RIPA, the left inferior phrenic arteries, and HCCs were measured, and the origin of RIPA and the location of HCCs were recorded. The CT findings in these 15 cases were correlated with arteriographic images. Results CT showed RIPA on the right diaphragmatic crus as high attenuation in all patients. The origin of RIPA was demonstrated in 11 cases. The diameter of the RIPA (3.1?1.1) mm was larger than that of the left inferior phrenic artery (1.3?0.4) mm ( P

OBJECTIVETo explore clinical efficacy of double Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I in treating acromioclavicular dislocation with Rockwood type III - V .

METHODSFrom January 2010 to September 2013, 56 patients with Rockwood type III - V acromioclavicular dislocation were treated by operation, including 20 males and 36 femlaes, aged from 32 to 52 years old with an average of 38.5 years old. Twenty-five patients were on the left side and 31 cases on the right side. The time from injury to operation was from 3 to 14 days, averaged 7 days. All patients were diagnosed as acromioclavicular dislocation with Rockwood type III - V, and double Endobutto were used to reconstituting coracoclavicular ligament, line metal anchors were applied for repairing acromioclavicular ligament. Postoperative complications were observed, Karlsson and Constant-Murley evaluation standard were used to evaluate clinical effects.

RESULTSAll patients were followed up from 8 to 24 months with average of 11 months. According to Karlsson evaluation standard at 6 months after operation,42 cases were grade A, 13 were grade B and 1 was grade C. Constant-Murley score were improved from (42.80±5.43) before operation to (91.75±4.27) at 6 months after operation. All items at 6 months after operation were better than that of preoperative items. Forty-eight patients got excellent results, 7 were moderate and only 1 with bad result. No shoulder joint adhesion, screw loosening or breakage were occurred during following up.

CONCLUSIONDouble Endobutto reconstituting coracoclavicular ligament combined with repairing acromioclavicular ligament in stage I for the treatment of acromioclavicular dislocation with Rockwood type III - V could obtain early staisfied clinical effects, and benefit for early recovery of shoulder joint function.

Objective To investigate the influence of body temperature on the recovery from vecuronium-induced neuromuscular block.Methods Sixty-eight ASA I - II patients (39 male, 29 female) aged 19-69 yr undergoing elective surgery under general anesthesia were randomly divided into 2 groups: group I in which patients' body temperature was maintained at 37 ℃ using warming blanket; group II in which no measures were taken to maintain the patients' body temperature. The patients were premedicated with phenobarbital 2 mg?kg-1 and atropine 0.01 mg? kg-1 intramuscularly. Anesthesia was induced with fentanyl 5 ?g? kg -1, propofol 2 mg? kg-1 and vecuronium 0. 1 mg?kg-1 . After tracheal intubation anesthesia was maintained with inhalation of 0.8%-2.5% isoflurane and propofol infusion at a rate of 2-4 mg ? kg-1? h-1 .Neuromuscular block was monitored using accelograph (Biometer, Denmark) .The changes in TOF and T1 were monitored. T1was maintained at 10% by vecuronium infusion during operation. At the end of operation a bolus of vecuronium 80?g ? kg-1 was given intravenously and T1 was completely depressed. The time for T1 to returned to 5% ,25% and 90% and the time required for T1 to return from 25 % to 75 % were recorded. The total amount of vecuronium given was recorded. Temperature probe was placed in the esophagus ( core temperature) . The room temperature was also recorded. Results The body temperature was lower, the total dose of vecuronium was smaller and the vecuronium-induced neuromuscular block lasted longer in group II as compared with group I . There was close correlation between body temperature and vecuronium-induced neuromuscular block. Conclusions Lower core body temperature could prolong the vecuronium-induced neuromuscular block.

OBJECTIVETo study the effect of Guishen Pill (GSP) on expression levels of Oct-4, MVH, and Egr-1 in mice with diminished ovarian reserve (DOR).

METHODSTotally 40 female C57BL/6J mice were randomly divided into 4 groups, the normal control group, the model group, the GSP group, and the dehydroepiandrosterone (DHEA) group, 10 in each group. Pregnant mare serum gonadotropin (PMSG), human chorionic gonadotropin (HCG), and prostaglandin F2α (PGF2α) were sequentially administrated to produce superovulation. The DOR model was established by exposing to ozone inhalation. Mice in the GSP group were intragastrically administered with GSP at 0.3 mL. Those in the DHEA group were intragastrically administered with DHEA at 0.3 mL. Equal volume of normal saline was intragastrically administered to mice in the normal control group and the model group. All mice wer treated for 21 days. Serum levels of estrogen (E2), progestogen (P), and anti-Müllerian hormone (AMH) were measured by ELISA. Changes of Oct-4, anti-AMH, and early growth response gene-1 (Egr-1) mRNA in ovaries were dtected by Real-time PCR.

RESULTSCompared with the model group, serum levels of E2, P, and AMH, as well as contents of estrogen receptor (ER), progestogen receptor (PR), MVH, and Oct-4 mRNA significantly increased in the GSP group and the DHEA group (P < 0.05).

CONCLUSIONGSP could improve expression levels of Oct-4, MVH, and Egr-1 mRNA in DOR mice and their ovarian function.

Objective To investigate the cause of metastatic metatarsalgia after hallux valgus surgery and the clinical outcomes of Weil osteotomy for metastatic metatarsalgia after hallux valgus surgery. Methods From July 2009 to Janurary 2012, data of 27 patients (27 feet) with metastatic metatarsalgia of 2nd to 4th head of metatarsal bone after hallux valgus surgery who had been treated by Weil osteotomy were retrospectively analyzed. There were 1 male and 26 females with an average age of 51 years (range, 28-73 years). Metatarsalgia occurred 6-24 months after operation for hallux valgus. 13 feet underwent mini-invasive cervi-cal wedge osteotomy of the first metatarsal, 7 with Chevron procedure, 5 with Akin procedure, and 2 with Lapidus procedure. No shortening in first metatarsal was found in 5 feet with Akin osteotomy, while there were varying degrees of shortening in first meta-tarsal in the remaining 22 feet. The clinical results were evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS) scores. The preoperative and postoperative plantar pressure changes were tested by plantar pressure tester. Results 25 Patients were followed up for 12-42 months (average, 24 months). Among these 25 cases, the metatarsalgia of 23 cases were completely disappeared. The metatarsal plantar lateral metastatic pain occurred in the remaining 2 cases (2 feet) and 1 was relieved by the foot pad, 1 was cured by re-Weil osteotomy. AOFAS score was 46.82 ± 6.13 before surgery and 90.63 ± 1.65 after surgery. The VAS score was 7.5 (6, 7) before surgery and 0.5 (0, 1.0) after surgery. The last follow-up, according to the score of AOFAS toe metatarsophalangeal-interphalangeal joint, of which 23 cases were excellent, 1 good, 1 poor;the excellent and good rate was 96%(24/25). Preoperative pressure under 2nd to 5th metatarsal head were 3.12±1.62 Pa, 5.81±1.92 Pa, 4.63± 2.10 Pa, 3.37±1.57 Pa, 1.67±1.20 Pa and postoperative were 3.33±1.35 Pa, 3.89±1.08 Pa, 3.65±1.96 Pa, 2.25±1.23, (1.48±1.11) Pa. Postoperative pressure under 2nd to 5th metatarsal head were significantly decreased. Conclusion Weil osteotomy can effec-tively adjust the length of the metatarsal and the height of metatarsal head, thus effectively improve the pressure under the metatar-sal head, so it could reach a good effect in the treatment of metastatic metatarsalgia after hallux valgus surgery.

LFA-1/ICAM-1 costimulation plays an important role in immunologic reaction of many different T cell populations. After TCR/CD3 complex cross-linking MHC/peptide, LFA-1, expressed on T cell increases a higher affinity and avidity for ICAM-1 rapidly. LFA-1 is a key molecule in formation of the immune synapse. LFA-1/ICAM-1 costimulation can engage various signaling events of T cell by up-regulating the activities of PI 3-kinase, sphingomyelinase, and c-Jun NH2-terminal kinase. With the costimulation of LFA-1/ICAM-1, engagement of TCR molecules results in a significant increase of T cell activities, including higher Th1 cytokines production, strongly proliferative response and higher T cell cytotoxicity.

Objective To detect the differentially expressed microRNAs (miRNAs) in bladder cancer tissue and normal bladder tissue. Methods Total RNA was extracted from bladder cancer tissue and normal bladder tissue by Trizol, and then miRNAs were isolated and enriched from the total RNA. Mammalian miRNA microarrays were used to analyze the differentially expressed miRNAs between the bladder cancer tissue and normal tissue. Data analysis was performed by software of LuxS-can3. 0 and SAM version 2. 1. Choose let-7 gene which was interesting to us, and validation of mi-croarray results was carried out by northern blotting. Results Compared with normal bladder tissues, there were 71 differentially expressed miRNAs in bladder cancer tissue, of which there were 38 down-regulated ones and 33 up-regulated ones. Among these miRNAs, 26 miRNAs were the most significant with 12 up-regulated and 14 down-regulated. The expression of let-7 gene in bladder cancer was down-regulated to normal bladder tissue by northern blotting, which was in agreement with the results of the miRNA microarrays. Conclusion There are differentially expressed miRNAs between bladder cancer tissue and normal bladder tissue, and let-7 gene is probably as a tumor suppressor in bladder cancer.
