Changes of patients' vital signs and nerve function were observed after the operation, and rehabilitation training and instruction were performed.ResultsAll cases were followed up for 2～37 months. Except one case died of tumor transfered to lung, all of other cases had a satisfactory curative effect in the near future, and their local symptom released and the functions of urination and defecation were kept well.ConclusionRehabilitation nursing in the peri-operative period plays an important role in surgical treatment of sacral tumor. It affects the rehabilitation and function restitution obviously and can reduce the occurrence of complication effectively.

Objective To describe our experience in laparoscopic radical prostatectomy (LRP)for incidental prostate cancer after TURP. Methods From April 2007 to July 2010, 5 patients with incidental prostate cancer after TURP were treated with a mean age of 73 years. The patients underwent LRP (2.8± 1.1) months after TURP. Results The five cases of LRP were performed successfully, with 1 case of transperitoneal approach and 4 cases of extraperitoneal approach. Mean operation time was (227.6±38.4) min, mean blood loss was (130±152.5) ml, and the mean follow-up was (16.1 ± 15.9) months. All five patients survived, and their urinary function was good without any incontinence. Conclusions Previous TURP represents a technical challenge when performing LRP, but highly skilled surgeons trained to perform LRPs can handle it.

Referring to the rules for agricultural seed testing (GB /T 3543-1995) issued by China, the test of sampling, seed purity, weight per 1 000 seeds, seed moisture, seed viability and germination rate had been studied for screening seed quality test methods of Pesudostellaria heterophylla. The seed quality from different collection areas was measured. The results showed that at least 6.5 g seeds should be sampled and passed through 10-mesh sieve for purity analysis. The weight of 1 000 seeds was determined by using the 500-seed method. The phenotypic observation and size measurement were used for authenticity testing. The seed moisture was determined under the higher temperature (130 ± 2) degrees C for 5 hours. The seeds were dipped into 0.2% TTC sustaining 1 hour at 40 degrees C, then the viability could be determined. The break dormancy seeds were cultured on sand at 10 degrees C. K cluster analysis was applied for the data analysis, the seed quality from different collection areas grading of P. Heterophylla was described as three grades. The seed quality of each grade should reach following requirements: for first grade seeds, germination rate ≥ 86%, 1 000-grain weight ≥ 2.59 g, purity ≥ 87%, moisture ≤ 13.1%; for second grade seeds, germination rate ≥ 70%, 1 000-grain weight ≥ 2.40 g, purity ≥ 77%, moisture ≤ 14.3%; for third grade seeds, germination rate ≥ 41%, 1 000-grain weight ≥ 2.29 g, purity ≥ 76%, moisture ≤ 15.8%. The seed testing methods for quality items of P. heterophylla had been initially established, as well as the primary P. heterophylla seed quality classification standard.

Background Rapamycin(RAPA)is a specific inhibitor of the mammalian target of rapamycin (mTOR).Researches showed that RAPA inhibits the proliferation of lens epithelium cells(LECs)and tumor cells and induces apoptosis of tumor cells.To investigate whether rapamycin has the inhibitory effect on retinal pigment epithelium(RPE)cells is very important for the prevention and management of proliferative vitreoretinopathy (PVR).Objective This study was to investigate the effects of RAPA on the proliferation and apoptosis of human RPE cells in vitro.Methods Human RPE cells(D407 strain)were cultured and passaged and then divided into regular culture group(blank control group),DMSO control group(0.1‰ DMSO +regular culture),and different concentrations RAPA-treatment groups(5,10,20,40,80,160,320 nmol/L).The proliferation(A490)of human RPE cells was detected using MTT,and the inhibitory rates of RAPA on the proliferation of RPE cells were calculated and compared among different groups at 12,24 and 48 hours.The apoptosis rates of the cells were analyzed among various groups by Hoechst staining after 12,24,48 hours.Results The inhibitory rates of RAPA on RPE cells were significantly different among various groups(F=484.451,P＜0.01)and evidently elevated in 20-320 nmol/L RAPA groups compared with DMSO control group(P ＜ 0.01).The inhibition of RAPA on the cells was considerably enhanced as the lapse of time(F=232.262,P＜0.01)with more dominant effects in 24 and 48 hours compared to 12 hours after addition of RAPA(P＜0.05-0.01).Compared with blank control group and DMSO control group,the apoptotic rates of the cells were evidently increased in 12,24,48 hours in 10 nmol/L RAPA group(all P＜0.05),and higher cellular apoptotic rates were found in 20-320 nmol/L RAPA groups(all P＜0.01).The alteration of cellular apoptotic rate showed a gradually incremental trend as the acting time of RAPA(F =625.584,P＜0.01).Karyorrhexis and mass-like density staining and chromatin substance were seen in RPE cells under the fluorescence microscope in ≥ 10 nmoL/L RAPA groups.Conclusions RAPA suppresses the proliferation and induces the apoptosis of human RPE cells in concentration-and time-dependent manner in vitro.

OBJECTIVETo analyze the efficacy and safety of bicyclol combined with thymosin in treatment of chronic viral hepatitis B (CHB).

METHODSA total of 135 patients with CHB were randomized into experimental group and control group. The patients in the experimental group received bicyclol orally 75 mg daily and thymosin 20 mg intramuscular injection once every 2 days for 24 weeks and those in control group received bicyclol orally 75 mg daily alone for 24 weeks. The levels of serum aminotransferase (ALT/AST), HBV-DNA, HBeAg /antiHBe were observed.

RESULTSCompared with pre-treatment levels, the serum aminotransferase levels decreased significantly in both groups, but there were no statistically significant differences between them. HBeAg negative conversion rate was significantly higher in the experimental group than in the control group (35.3 percent vs.19.4 percent, P less than 0.05). HBV DNA negative conversion rate was significantly higher in the experimental group than in the control group (36.7 percent vs. 20.9 percent, P less than 0.05). No obvious adverse events which were probably related to the drugs were observed in this study.

CONCLUSIONThe combination of bicyclol with thymosin had better effect in treatment of chronic hepatitis B ias compared with bicyvlol alone.

OBJECTIVETo investigate the effects of inward rectifier potassium channel blockers (BaCl2, CsCl) on the functions of endothelial progenitor cells (EPCs).

METHODSDensity gradient centrifugation-isolated rat hone marrow mononuclear cells were cultured in vitro. EPCs were harvested and seeded on six culture dish when cells grew to 3-5 passages. Before testing the EPCs were synchronized with M199, which contain 2% fetal calf serum. In the end, EPCs were treated with different intervention. The experiment mainly included two parts: (1) BaCl2 (100 micromol/L) and free BaC2 of Tyrodes solution; (2) CsCl (1 mmol/L) and control. Cell pretreated with blockers above mentioned for 12 h, then the gene expression of stromal cell-derived factor-1 (SDF-1), epoprotenol (PGI2) were assessed, beyond that the ability of adhesion, migration were assayed with different tests. In addition, the medium was collected when EPCs were treated for 3 days. The levels of SDF-1 were measured by sandwich enzyme-linked immunosorbent assay (ELISA). Going even further, EPCs were treated with the signal pathway blockers in advance, after repeat the above steps, in order to analyze the change of SDF-1 and then discuss its mechanism.

RESULTSCompared with control group, BaCl2, CsCl could increase EPC adhesion and migration to same extent. Moreover, the gene expression of SDF-1, PGI2 was significantly up-regulated and the production of SDF-1 increased evidently. Furthermore, the mechanism of SDF-1 secretion increasing mainly was associated with eNOS signaling pathways.

CONCLUSIONBa2+ and Cs+ play important roles in increasing EPCs functions, such as adhesion, migration and secretion.

OBJECTIVETo explore a new technique for repair of alveolar cleft by sutural distraction osteogenesis.

METHODSNine 8-weeks mongrel dogs were used in this study, three being in the control group, six in the experimental group. Alveolar cleft model was created surgically in all animals. Two weeks later, a U-shaped distractor made of Ni-Ti memory alloy wire was insterted into the premaxilla to distract the mid-premaxillary suture. When the premaxilla of the cleft side approached the ipsilateral maxilla, periosteoplasty of the alveolar cleft was performed. The distractor was removed at two weeks after periosteoplasty. The results were evaluated clinically, radiographically, morphologically and histologically.

RESULTSThe cleft model in dogs was stable and similar to the human alveolar cleft. In experimental dogs, the premaxilla was moved gradually toward the maxilla so that the cleft was closed. The distracted mid-premaxillary suture showed a gradually widened traingle, with its tip being posterior. The density of the distracted traingle suture was increased gradually. Bony repair was achieved completely at the cleft three months post-periosteoplasy. The morphology of the mid-premaxillary suture was restored.

CONCLUSIONThe alveolar cleft could be repaired by the technique of mid-premaxilla suture distraction.

OBJECTIVETo observe the effect of parecoxib on morphine dosage in patient-controlled analgesia (PCA) following thoracoscope-assisted thoracotomy.

METHODSA consecutive series of 100 patients undergoing thoracoscope-assisted thoracotomy were randomized into 5 groups and received PCA with morphine doses at 0, 5, 10, 15, and 20 mg given in 200 ml saline (groups P(1), P(2), P(3), P(4), and P(5), respectively). Parecoxib (40 mg) was given in all the patients immediately before the operation, and the mixture (4-5 ml) of lidocaine and ropivacaine was administered into the 3 intercostal spaces upper and lower to the incision before chest closure. PCA was administered for each patient. The visual analogue scale (VAS) at rest and coughing and the respiratory functional parameters were recorded at 1, 2, 4, 8, 12, 24, 36, and 48 h after the start of PCA, and the actual and effective button-pressing times (D(1)/D(2)) in PCA were also recorded.

RESULTSNo patients showed signs of respiratory inhibition within 24 h after the operation, and the resting VAS was comparable between the groups within the initial 6 postoperative hours. At 8 to 24 h postoperatively, the VAS scores at rest and coughing were significantly higher in P(1) group than in the other groups (P<0.05), and no significant differences were found between the groups at 36 to 48 h. D(1)/D(2) in groups P(1) and P(2) were significantly different from those in the other 3 groups at 4-24 h, but no such difference was found between groups P(3), P(4), and P(5).

CONCLUSIONThe application of parecoxib may reduce the dosage of morphine in PCA following thoracoscope-assisted thoracotomy and results in good analgesic effect without affecting the patients respiratory function and sputum elimination.
