Thirteen patients with colorectal lesions underwent laparoscopic surgery from January to December 2019. Before surgery, 5.0 ml autogenous blood was injected under colonoscopy into the inferior margin and opposite sides of the lesion for localization. The operation time，success rate，complications，location efficiency and postoperative pathology were evaluated. The autologous blood tattooing was easily applied for all patients without complication. At laparoscopic surgery，the lesions of all patients were clearly visualized except one obese patients with rectal tumors, because the tumor was located below the retroperitoneal fold. No blood diffusion and leakage，and local inflammatory responses were observed. The surgical margins of all samples were tumor negative. Preoperative tattooing with autologous blood is recommended as an easy，safe and economical procedure for colonoscopic surgery in patients with colorectal lesions.

Chronic osteomyelitis is one of the most common disorder in clinic. In recent years due to diabetes, peripheral vascular disease and trauma induced disease increased, the prevalence rate increased. With the development of magnetic resonance imaging and CT imaging technology, it greatly improved the accuracy of clinical diagnosis of chronic osteomyclitis and ability to describe the infection characteristics, and provide a reliable basis for clinical treatment. The current research on chronic osteomyelitis mainly concentrated on the aspects of imaging applications and ways of using antibiotic optimization control inflammation, defect restoration and reconstruction of blood supply and treatment. But the best time to the antibiotic therapy and the use of program is still uncertain, for after debridement, bone grafting time and defect repair function of fast recovery still need further research.

Osteoclasts are multinucleated giant cell, which derived from mononuclear myeloid hematopoietic stem cells with the function of bone absorption. Osteoclasts plays a key role in bone metabolism, therefore the body is very strict to regulation of osteoclastogenesis. Mobilization and differentiation of osteoclast maturation is a complex and sophisticated multi-level regulatory processes. In the relevant regulatory mechanisms, OPG/RANKL/RANK system plays a pivotal role in the process of osteoclast differentiation and maturation. Recent studies revealed that immune cells and osteoclasts were closely connect with each other in the field of bone metabolism, also provide a new therapeutic target for the treatment of bone diseases. The apoptosis of osteoclasts in bone metabolism have been payed more attention,while its mechanism is still not clear, which need further research.

OBJECTIVETo investigate the protective effect of phosphodiesterase type 5 inhibitors (tadalafil) on the testis following testicular ischemia-reperfusion injury in rats.

METHODSEighty-four healthy adult male SD rats were randomly and equally divided into groups A (sham operation), B (testicular torsion + low-dose tadalafil), C (testicular torsion + high-dose tadalafil), and D (testicular torsion + placebo). Models were established in the latter three groups by 7200 torsion of the right testis for 2 hours. The animals in groups A and B were treated by gavage with tadalafil at the dose of 0. 5 mg per kg per day, those in group C at 2 mg per kg per day, and those in group D with saline at the same dose. After 3, 7, and 14 days of treatment, the torsioned testes were harvested for evaluation of the superoxide dismutase (SOD) activity and malondialdehyde (MDA) content in the testis tissue. The pathological changes in the testis were observed under the light microscope.

RESULTSAt 3, 7, and 14 days, the SOD activity was (254.46 +/- 7.43), (278.49 +/- 8.33), and (317.99 +/- 3.31) nU/mg prot in group B, and (277.12 +/- 8.80), (309.40 +/- 2.14), and (320.39 +/- 4.72) nU/mg prot in group C, all obviously higher than in D ([223.21 +/- 4.65], [231.45 +/- 4.16] and [248.28 +/- 5.74] nU/mg prot), while the MDA content was lower in the former two groups than in the latter. At 3 and 7 days, the SOD activity was significantly higher and the MDA level significantly lower in group C than in B (both P < 0.01) , while at 14 days, neither showed any remarkable differences between the two groups (P > 0.05). No obvious histopathological change was observed in the testis tissue of group A. At 3 and 7 days, pathological examination of the testis tissue revealed significant differences in the number of seminiferous epithelial layers, testicular histological score, and seminiferous tubule diameter in group B (P < 0.01), but the three indexes at 14 days in group B and at 7 days in group C exhibited no remarkable differences from those at 14 days in group A.

CONCLUSIONTadalafil can alleviate testicular ischemia-reperfusion injury following testis torsion/detorsion in a time- and dose-dependent manner.

OBJECTIVETo investigate clinical effects of auricular acupoint (AA) in the treatment of analgesia during perioperative period in total hip arthroplasty.

METHODSFrom March 2008 to August 2010, 60 patients with late osteonecrosis of the femoral head were treated by total hip arthroplasty and randomly divided into auricular acupuncture (AA) group and control group, 30 patients in each group. There were 11 males and 19 females in the AA group,with an average age of (60.93 +/- 5.90) years; the patients were treated with auricular acupuncture on the point of Shenmen, Subcortex, Kidney and hip joint for four times a week. There were 12 males and 18 females in control group, with an average age of (59.87 +/- 6.21) years; while the patients without auricular acupuncture. VAS score was used to evaluat the degree of pain; Harris score was used to evaluat the function of hip joint. All patients received patient controlled analgesia pump (PCA) for 48 hours after surgery (400 ml liquids were in PCA pump, including 800 mg tramadol and 0.8 mg fentanyl). The dosage of liquids and adverse reaction of PCA pump in different time were recorded.

RESULTSThe VAS score on the 3rd, 4th, 5th and 7th day separately was (3.61 +/- 0.29), (3.59 +/- 0.30), (2.97 +/- 0.26), (2.29 +/- 0.45), and lower than control group, which separately was (4.19 +/- 0.28), (4.00 +/- 0.31), (3.15 +/- 0.29), (2.83 +/- 0.31). The dosage of PCA in AA group separately was (72.27 +/- 8.06), (60.40 +/- 8.16), (44.13 +/- 4.75), (40.40 +/- 3.69), and less than control group, which was (86.27 +/- 8.51), (73.87 +/- 8.32), (54.53 +/- 5.20), (44.67 +/- 6.31) on the time of 0-12, 12-24, 24-36 h and 36-48 h after surgery. During the using of PCA, nausea and vomiting occurred in 5 cases, less than control group (21 cases). Harris score in AA group (78.90 +/- 5.14) was higher than control group (73.37 +/- 5.99) 2 weeks after operation.

CONCLUSIONAuricular acupuncture can reduce postoperative pain, reduce the usage of analgesic and complications, such as nausea and vomiting, improve the function of hip joint after operation.

To explore the influence of raising oxygen (dissolved oxygen) content on function of platelet concentrate, the platelet concentrate was prepared by a CS-3000 plus blood cell separator. Experiments were divided into 2 groups: test group and control group. After raising oxygen content in platelet plasma under sterile operation, the platelet samples of two groups were preserved in oscillator with horizontal oscillation at 22 +/- 2 degrees C. The platelet count, platelet aggregation rate, lactic acid content and CD62p expression level of platelet were detected on 0, 1, 2, 3, 4, 5 days of platelet preservation. The results showed that the platelet count and platelet aggregation rate decreased with prolongation of preserved time, while the lactic acid content and CD62p expression level of platelet increased gradually. Compared with control group, there were significant differences in aggregation rate of platelet preserved for 2-3 days, and in CD62p expression level of platelet preserved for 1-3 days, while significant difference was found in lactic acid content of platelet preserved for 1-3 days. It is concluded that raising content of oxygen in platelet plasma can provide more oxygen to compensate oxygen supply deficiency for platelet metabolism and improve the efficiency of platelet oxygenic metabolism and the quality of platelet during preservation.

Objective To evaluate the effect of liver transplantation for end-stage autoimmune liver disease (ESALD) and summarize the clinical experience of liver transplantation in the treatment of ESALD.Methods The clinical data of 11 ESALD cases who underwent liver transplantation from September 2003 to July 2009 were analyzed retrospectively. There were 2 males and 9 females ( median age, 44. 2 ± 8. 7years). The indication of liver transplantation was end stage of primary biliary cirrhrosis (8 cases),autoimmune hepatitis (2 cases), and primary sclerosing cholangitis ( 1 case). In all cases, modified piggyback liver transplantation with venacavaplasty was carried out. Postoperatively all patients were treated with immunosuppressive agents including tacrolimus (or cyclosporine A) and prednisone, some patients were treated additionally with mycophenolate mofetil and ursodeoxycholic acid. Results Postoperatively 2patients of primary biliary cirrhosis died, one of lung infection and multiple organ failure on the 5th postoperative day, the other dying of sepsis and graft dysfunction on the 964th postoperative day. Five cases suffered from episodes of acute cellular rejection within 1 month after transplantation and was successfully reversed by strengthened immunosuppressive therapy. Nine patients recovered satisfactorily and with excellent life quality until now. Patients were followed up from 7 months to 62 months with the median follow-up time of 38 months. The recipient survival rate at 1 year and 3 years was 91% and 82% ,respectively. One patient has now survived for 5 years. No recurrent ALD case was found during follow up.Conclusions Orthotopic liver transplantation is an exclusive treatment for ESALD. Optimum operation timing and effective immunosuppressive treatment are very important for decreasing occurrence of complications.

OBJECTIVETo investigate the risk factors for pulmonary Candida infection in association with mechanical ventilation and analyze the drug resistance profile of the Candida species that cause the infection.

METHODSA retrospective analysis was conducted 114 patients receiving mechanical ventilation for over 48 h. According to the presence of pulmonary Candida infections, these patients were divided into infected group (n=50, 43.9%) and non-infected group (64 cases). Univariate analysis and multivariate logistic regression analysis were performed to identify the risk factors for the infection, and drug sensitivity test was carried out to evaluate the drug resistance of the Candida species.

RESULTSUnivariate analysis and multivariate logistic regression showed that the presence of at least two underlying diseases (OR=4.758, P=0.009), frequent changes of antibiotics (OR=6.128, P=0.001), and blood albumin below 25 g (OR=15.829, P=0.011) were the independent risk factors for pulmonary Candida infection associated with mechanical ventilation, and prophylactic antifungal treatment (OR=0.062, P=0.012) was a protective factor. Drug sensitivity test showed that Candida albicans was sensitive to most of the antifungal agents (100.0%), but the non-albicans Candida species were resistant to fluconazol (50.0%) and Itraconazole (38.5%).

CONCLUSIONPoor general conditions and frequent changes of antibiotics are the major risk factors for pulmonary Candida infection in patients receiving mechanical ventilation. Drug resistant analysis is helpful in the treatment of the infections.
