Objective Through comparative study of the rate and influence factors of intraoperative and postoperative complications of cervical cancer after laparoscopic radical hysterectomy which to guide the clinical practice of this kind of surgery in the future. Methods The clinical data of 314 patients undergoing laparoscopic radical hysterectomy from January 2013 to December 2015, the complication rate was observed, and the inlfuencing factors were analyzed by the method of multiple factor analysis. Result The number of intraoperative complications were 20 cases, accounting for 6.37%, the number of postoperative complications were 80 cases, accounting for 25.48%. Intraoperative complications influence factors including FIGO, surgery time, doctors surgery experience [OR^ =2.00, 95%CI (1.00~4.25)] which have the highest value. postoperative complications inlfuence factors including age, body mass index (BMI), lymph node metastasis, FIGO, doctors surgery experience, operative time [O^R=4.69, 95%CI (1.05~2.84)] which have the highest value. Conclusions Complications are dififcult to avoid completely, but we can reduce it by age, BMI, lymph node metastasis, FIGO, operation time, doctor’s operation experience and so on.

Objective To evaluate the clinical value of sentinel lymph nodes (SLN) in predicting pelvic lymph node status for early cervical squamous cell carcinoma,and approach the clinical significance of SLN detection for guiding radical abdominal trachelectomy (RAT).Outcomes of follow up and fertility were also observed.Methods A total of 31 patients with stage Ⅰ a2-Ⅰ bl squamous cell carcinoma planned to be given RAT and pelvic lymphadenectomy were enrolled.99mTe-labeled phytate was injected before surgery.Intraoperatively,SLN were identified,excised,and submitted to fast frozen section.Systematic bilateral pelvic lymphadenectomy was performed,and then RAT was performed in patients with negative SLN.All nodes were sent for routine pathological examination and immunostained with anti-cytokeratin antibody to detect micrometastases.Results SLN were detected in all patients (100％,31/31).A total of 109 SLN were identified with a mean number of 3.5 per patient.Of these,SLN of 2 patients were positive on frozen sections and proved to be metastasis by final pathologic examination and quitted the RAT.No missed micrometastasis was found using immunohistochemical staining in SLN and other lymph nodes using histologically node-negative cases.No false negative cases was found and the negative value was 100％ (31/31).The sensitivity,accuracy,and false negative rates were 100％,100％,and 0,respectively.Perioperative complications occured in 5 patients including 2 cases of bladder injury and 3 cases of uterine artery injury.No relapses occurred during follow-up.Five of 19 patients with procreative desire conceived pregnancies (4 spontaneous abortion and 1 premature birth) after surgery.Conclusions The identification of SLN using 99mTc-labeled phytate could predict the pelvic lymph node status in early stage cervical cancer.Under the guidance of SLN detection,RAT is a feasible operative modality with well prognosis and low complications for young patients who desire to preserve reproductive function.

Objective To investigate the correlation between pathogens and spectrum of disease in infants with human cytomegalovirus(HCMV) active infection.Methods A total of 378 cases of HCMV infection diagnosed by the identification of HCMV IgM or PP65 antigen of HCMV.HCMV gB genotyping was carried out by nested PCR and restriction fragment length polymorphism(RFLP) in 107 cases.The results of pathogen,spectrum of disease and clinic feature were analyzed.Results In all 378 infant patients with HCMV,27.78% were systemic infection and 72.22% involved just single organ.Hepatitis,HCMV inclusion disease,thrombocytopenic purpura,pneumonia were pre- dominant with 33.07%,27.78%,13.49%,6.35% respectively.The rate of HCMV inclusion dis ease in infants younger than 2 weeks was higher than in those aged from 3 12 weeks(P ~ 0.05) and children older than 12 weeks(P＜0.01).Infants with higher rate of PP65 antigen positive cells were apt to systemic infection than those with lower rate of PP65 positive cells(P＜0.01).Infants,who were positive by detections of all three methods,were apt to systemic infection than others(P＜0.01). Moreover,infants positive of IgM and PP65 antigen were apt to systemic infection than those just positive by one of the two methods(P＜0.01).The result of gB genotype analysis in 107 cases showed 53 cases of gBⅠ,20 of gBⅡ.18 of gBⅢ.7 of gBⅠ+gBⅡ,5 of gBⅠ+gBⅢand 4 of gBⅡ+gBⅢ,and gBⅣwas not found.Conclusion HCMV could infect multiple organs and have some different clinic features.Combination of different methods can increase the sensitivity to detect the pathogen.The gBⅠgenotype is most prevalent in these infants.

OBJECTIVETo investigate the early clinical effects and radiological outcome of dynamic cervical implant (DCI) internal fixation in treating cervical spondylosis, and evaluate its safety and efficiency.

METHODSFrom June 2009 to December 2011, 19 patients with cervical spondylosis correspond to the indication of DCI internal fixation in the study, including 5 cases of cervical spondylotic myelopathy and 14 cases of cervical spondylotic radiculopathy. There were 8 males and 11 females, aged from 35 to 54 years with a mean of 43.2 years. Pathological segments included C3,4 in 1 case, C4,5 in 6, C5,6 in 6, C6,7 in 4, C3,4 and C5,6, C6,7 in 2. All patients were treated with anterior discectomy and decompression and DCI internal fixation, meanwhile, 2 cases of them with anterior cervical corpectomy and fusion plate fixation. Clinical evaluation included Modified Japanese orthopedics association (mJOA), neck disability index (NDI), visual analogue scale (VAS) score and patient satisfaction index (PSI) at pre-operation and final follow-up. Radiographic evaluation included flexion/extension lateral view at operative level and adjacent segment. The adjacent level degeneration was analyzed according to Miyazaki classification on MRI images.

RESULTSAll patients were followed up from 12 to 42 months with an average of 19.8 months. Preoperative mJOA score was 13.6±1.1 and at final follow-up was 16.3±1.2 with improvement rate of 85.0%. Preoperative VAS,NDI was 6.6± 1.4, 17.1±7.4 and at final follow-up was 1.4±0.8, 6.1±3.9, respectively; there was statistical significance in all above-mentioned results between preoperative and final follow-up (P<0.05). Preoperative ROM at operation level was (7.6±1.9)° and final follow-up was (7.8+2.1)°; preoperative ROM at C2-C7 was (38.6±7.2)° and final follow-up was (39.9±6.4)°; there was no statistical significance in all above-mentioned results between preoperative and final follow-up (P>0.05). Preoperative DHI at operation level was (6.3±1.1) mm and final follow-up was (7.1±0.8) mm, there was statistical significance in DHI between preoperative and final follow-up (P<0.05). No heterotopic ossification was found. All patients followed up MRI, degeneration of 3 segments aggravated 1 degree in 38 adjacent segments, without clinical symptom.

CONCLUSIONTreatment of cervical spondylosis with dynamic cervical implant can got satisfactory outcome in early follow-up. Activity of operative segment obtain reservation in some degree. The incidence of adjacent segment degeneration is lower and no adjacent segment disease occur. Nevertheless a longer follow-up time should be needed to assess the long term functionality of the DCI and the influence on adjacent levels.
