Objective To discuss the clinical significance of human papilloma virus (HPV) infection in cervical cancer and to explore the feasibility of detecting the infection with microarray from paraffin-embedded specimens of cervical cancer. Methods From May 2005 to February 2007, 48 patients with cervical carcinoma, including 37 cases with cervical squamous cell carcinoma and 11 cases with cervical adenocarcinoma, were analyzed retrospectively. After DNA extraction from the paraffin-embedded tissues, 23 HPV subtypes were detected by the use of microarray after amplification by polymerase chain reaction (PCR) and hybridization. Results 44 cases of cervical cancer were found to be high-risk HPV positive genotypes. The HPV infection rate was 91.7%. The HPV infection rate in cervical squamous cell carcinoma was 94.6% (35/37), and in cervical adenocarcinoma was 81.8% (9/11). Among them, 33 cases were found to have single infection, accounting for 75.0% of the infection rate. There were 11 cases of mixed infection, among them 9 cases were found to have double infection and 2 cases with multiple infection, accounting for 20.5% and 4.6%, respectively, of the infection rate. The infection rate of HPV16, the main genotype, was 90.9% (40/44). The infection rate of HPV18, the second ranking subtype, was 27.3% (12/44). Infection with HPV52, 33, 59, and 68 genotypes was lower in incidence. Among 35 cases of cervical squamous cell carcinoma, the infection rates of HPV16 and HPV18 were 91.4% (32/35) and 22.9% (8/35), respectively. Among 9 cases of cervical adenocarcinoma, the infection rate of HPV16 and HPV18 were 88.9% (8/9) and 44.4% (4/9), respectively. Conclusion Multiple HPV genotypes can be detected from paraffin-embedded tissues with microarray technique in high sensitivity and specificity, and it is useful to study the pathogenesis and prevention of cervical cancer.

Objective To study the difference in immunomodulatory effects among non-Hodgkin lymphoma (NHL)-, Hodgkin lymphoma (HL)- and normal adult bone marrow-derived mesenthymal stem cells (MSCs). Methods MSCs were obtained from HL, NHL and normal adult bone marrow and cultured in expanded medium. Immunophenotype was investigated by FACS. The levels of cytokines were evaluated by enzyme linked immunosorbent assay (ELISA). T-cell suppression ability was evaluated by Transwell. Moreover, the immunoregulatory ability of HL-, NHL- and normal adult bone marrow-derived MSCs was detected by mixed lymphocyte culture assay. Results HL-, NHLand normal adult bone marrow-derived MSCs were similar in morphology and immunophenotype, and they did not express HLA-DR and co-stirnulatory molecules (CD40, CD80 and CD86). All HL-,NHL- and normal adult bone marrow-derived MSCs could significantly suppress T lymphocytes'proliferation in a dose-dependent manner and such an effect could be reversed by anti-TGF-β1 antibody.MSCs differentiated into various mesenchymal lineages did not alter their immunosuppressive effects on T-cell proliferation. Conclusion The similar immunomodulatory effects were found among HL-,NHL- and normal adult bone marrow-derived MSCs, which was not changed by differentiation.

Objective To study the clinical efficacy of robotic sacral hysteropexy in treatment of uterine prolapse.Methods From January 2012 to December 2013,3 patients undergoing robotic sacral hysteropexy in treatment of uterine prolapse in General Hospital of People's Liberation Army were studied retrospectively.Operation time,blood loss and postoperative recovery exhaust time and pelvic organ prolapse quantification (POP-Q) staging were evaluated.Results Three patients were treated by robotic sacral hysteropexy successfully.The mean operation time was 221 minutes (210-240 minutes),mean blood loss was 45 ml.One case with Ⅱ degree perineal laceration patients simultaneously perineal repair,neither intranor post-operative complications occurred.The mean postoperative recovery exhaust time was 16 hours.At three months of follow-up,all 3 patients got satisfaction.Although one patient at the first six months of postoperation had leakage of urine when coughing,instruct exercise pelvic floor muscle function and acupuncture one month their symptoms disappear.Conclusion Robotic sacral hysteropexy pave the way for an effective option in the management of uterine prolapse.

Objective To study ischemic effects on reentrant activities and cardiac arrhythmias using a computational approach. Method The Noble 98 mathematical model of ventricular cell was used in the study. The operator splitting and adaptive time step methods were utilized to integrate the partial differential equations in cardiac conduction models. The ischemic cells were simulated by decreasing the intracellular ATP concentration, reducing the Na+ conductance, and increasing the extracellular K+ concentration in a two-dimensional tissue. Spiral waves were initiated by the cross field technique. Result The results showed that spiral waves in local severe ischemia displayed three different morphologies,whereas in moderate ischemia only two kinds of wave forms exhibited. When the degree of ischemia reached a critical value, the reentrant wave could break. But for larger areas of ischemia spiral wave formed a typical functional reentry around the obstacle. Conclusion The study demonstrates that size and level of ischemia have effects on VTs and VFs. Large ischemic area is beneficial for maintenance of spiral wave and can provide a high probability in the genesis of VTs. Spiral waves can easily break up and degenerate into VFs under critical area or level of ischemia.

Objective To apply robotic surgery of early ovarian malignancy tumors clinically and evaluate its feasibility in management for early ovarian cancer. Methods Using the da Vinci robotic surgical system, seven patients with early ovarian malignancy tumors (stage Ⅰ) underwent robotic surgery from April 2012 to September 2013. The average age was 45.7 years. Robotic surgeries approaches contained salpingo-oophorectomy,para-aortic lymphadenectomy, pelvic lymphadenectomy, omentectomy and appendectomy. Perioperative and follow-up clinical data were recorded. Results All robotic surgeries were successfully completed without the conversion to laparotomy. The mean operative time was 225 minutes (100-330 minutes). The average estimated blood loss was 171 ml (20-600 ml). No patients received blood transfusions. No intraoperative and postoperative complications were observed. The average number of pelvic lymph node dissected were 18.3 (11-34). The average number of para-aortic lymph node dissected were 3.7 (3-4). The mean follow-up time was 26.0 months after surgery (20-36 months). Currently, all patients had no tumor recurrence and survived. Conclusion Robotic surgery is feasible as a novel alternative approach in the treatment of early ovarian malignancy tumors.

A 54-year-old man diagnosed with chronic lymphocytic leukemia (CLL) was admitted in our department in June 2014. After one cycle of FC chemotherapy, a bone marrow examination revealed normalized lymphocyte count and another acute myeloid leuke-mia (AML)-M5 clone. The patient refused sequential treatment and only received follow-up examination. He had continuous hemato-logically stable disease and died of pulmonary infection on July 2015. After a multidisciplinary team discussion, we confirmed the si-multaneous diagnosis of CLL and AML-M5. Through this discussion,tumor second hit model,tumor evolution model,andtumor heterogeneitywere further defined.

ObjectiveTo improve the understanding of chronic myelomonocytic leukemia associated with Sweet' s syndrome.MethodsRetrospective analysis of a case of chronic myelomonocytic leukemia associated with skin herpes was reported. Skin biopsy was performed. DA and CAG regiment were administrated.ResultsSweet's syndrome was diagnosed by skin biopsy.Corticosteroids therapy alone was not effective. Complete remission was achieved by CAG regiment and skin rash has been effectively controlled.Three months later Sweet' s syndrome relapsed and chronic myelomonocytic leukemia developed into acute myelomonocytic leukemia. ConclusionChronic myelomonocytic leukemia associated with Sweet's syndrome is rare but implies a quick progression to acute myelomonocytic leukemia.

Objective:To observe the effects of acupuncture and moxibustion at Feishu(BL13)on inflammatory responses and intestinal short-chain fatty acids(SCFAs)in rats with asthma. Methods:Fifty-six Sprague-Dawley rats were randomly divided into a normal group(16 rats)and a modeling group(40 rats).Rats in the modeling group were subjected to establishing asthma models using ovalbumin(OVA).Model evaluation was conducted using 4 rats from each group.The remaining rats that successfully developed asthma were then randomly divided into a model group,an acupuncture group,and a moxibustion group,with 12 rats in each group.Rats in the acupuncture group received acupuncture treatments,and those in the moxibustion group received moxibustion treatments,both at Feishu(BL13)for 30 min.Following the treatments,the rats were exposed to atomization excitation with a 1%OVA solution for 20 min daily for 14 consecutive days.At the end of the experiment,inflammatory markers in the rats'peripheral blood were analyzed using a biochemical method.In addition,inflammatory cells in the bronchoalveolar lavage fluid(BALF)were counted using Wright-Giemsa staining.The lung tissue of rats was examined under a light microscope after staining with hematoxylin-eosin to observe morphological or pathological changes.Furthermore,real-time fluorescence quantitative polymerase chain reaction was utilized to measure the mRNA expression of inflammatory factors in the lung tissue.Lastly,the concentration of SCFAs in the rat's feces was determined using gas chromatography-hydrogen flame ionization. Results:The levels of eosinophils(Eos),neutrophils(Neu),and lymphocytes(Lym)in the peripheral blood,as well as Eos and Neu in the BALF,and the expression of interleukin(IL)-4,IL-5,IL-13,IL-33,and thymic stromal lymphopoietin(TSLP)mRNAs in the lung tissue were all found to be significantly increased(P<0.05 or P<0.01);the lung tissue structure displayed severe injuries;the levels of acetic acid,propionic acid,isobutyric acid,butyric acid,and valeric acid in the feces decreased significantly in the model group(P<0.05 or P<0.01).Compared with the model group,the peripheral blood levels of Eos,Neu,and Lym,as well as Eos in the BALF,and the mRNA expression levels of IL-4 and IL-5 in the lung tissue decreased significantly in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).This reduction was accompanied by alleviated pathological damage in the lung tissue.Additionally,there were significant increases in the levels of acetic acid,propionic acid,isobutyric acid,and butyric acid in the feces in both the acupuncture group and the moxibustion group(P<0.05 or P<0.01).In the acupuncture group,the expression levels of Lym in the BALF and IL-13 mRNA in the lung tissue decreased significantly(P<0.05 or P<0.01).In the moxibustion group,the mRNA expression levels of IL-33 and TSLP in the lung tissue also reduced significantly(P<0.05 or P<0.01).Furthermore,the level of valeric acid in the feces increased notably in the moxibustion group(P<0.01).Compared with the acupuncture group,it was found that the mRNA levels of IL-5 and IL-13 in the lung tissue,as well as the acetic acid level in the feces,were significantly higher in the moxibustion group(P<0.05 or P<0.01). Conclusion:Both acupuncture and moxibustion were effective in reducing abnormal inflammation and regulating intestinal SCFAs in asthma model rats.Acupuncture demonstrated superiority in inhibiting pro-inflammatory factors,particularly IL-5 and IL-13,while moxibustion exhibited better regulation on intestinal metabolites SCFAs,especially acetic acid.
