Objective:To select suitable chemotherapy for cervical cancer patients by ATP-tumor chemosensitivity assay.
Methods:Seventy-two hospitalized patients with cervical cancer between July 2007 and October 2009 were enrolled. The patients were randomly divided into a trial group (n=35) and a control group(n=37). ATP-TCA was used to detect the sensitivity of 35 samples of cervical cancer in the trial group to 6 combined chemotherapy regimens. The chemotherapy regimen in the trial group was confirmed by the results of susceptibility testing and that in the control group was confirmed by clinical experience. One-year recurrence rate and 3-year survival rate of two groups were compared after 3 year follow-up.
Results:ATP-TCA was measured in 32 of the 35 patients in the trial group. The sensitive patients for paclitaxel+carboplatin, paclitaxel+oxaliplatin, bleomycin+ifosfamide+cisplatin, bleomycin+vincristine+cisplatin, fluorouracil+cisplatin, and gemcitabine+cisplatin were 20, 18, 17, 18, 17, and 21, respectively. There was no significant difference in the 1-year recurrence between the two groups (P>0.05), while the 3-year survivors in the trial group were more than those in the control group (P<0.05).
Conclusion:ATP-TCA method is good for patients with cervical cancer because it is sensitive, effective, and individualized.

Laparoscopic pancreas- and spleen-preserving splenic hilar lymph nodes dissection is still difficult to accomplish,which restrains its application in total gastrectomy for advanced proximal gastric cancer.Based on our anatomical understanding of pre- and retropancreatic spaces,features of splenic vessels and distribution of perigastric lymph nodes,we combined the characteristics of laparoscopic surgery and developed a novel technique for laparoscopic pancreas- and spleen-preserving splenic hilar lymph nodes dissection through retropancreatic space.The key lies in mobilization of the splenic pedicle through retropancreatic space,dissection of peri-vascular lymph nodes in sequence of trunk-to-branch,in-sheath vascularization of the splenic vessels.From August 2009 to December 2010,this technique was performed on 6 patients in Nanfang hospital.The initial results suggested that this technique could be safe and feasible for skillful surgeons.Further studies on the application of this technique in total gastrectomy for advanced proximal gastric cancer would be needed.

Correct implementation of laparoscopic total gastrectomy with D2 lymph node dissection depends on the understanding of anatomical features of peripancreatic space, the landmark of pancreas and blood vessels, and the diverse perigastric vascular anatomy and standardized surgical procedures designed according to the regional distribution of lymph nodes.From September 2006 to November 2009, laparoscopic total gastrectomy with D2 lymph node dissection surgery were completed in 12 cases in the Nanfang Hospital. A reasonable anatomy method and a simple, effective surgical procedure of laparoscopic D2 lymph node dissection were introduced.

Objective To understand the distribution situation of respiratory viral infection among adult inpatients with respiratory infection in the emergency department.Methods The detection results data of 5 kinds of viruses RSV,IVA,IVB,PIV1,PIV2,PIV3 and ADV by indirect immune fluorescence assay in 384 adults patients with respiratory infection in the emergency department of our hospital from January 2014 to December 2015 were collected.The epidemic characteristics of different viruses were analyzed.Results Among 384 specimens,208 cases were positive in respiratory virus IgM antibody,the viral infection positive rate was 54.17%.The mixed virus infection and influenza B virus infection were most common,their viral positive rates were 26.56% and 23.44% respectively,In the mixed viral infection,the positive rate of IVA + IVB mixed infection was highest,accounting for 87.25%,which was higher than that of other kinds of mixed viral infection.The viral infection positive rate had no statistical difference between different genders(P>0.05).The viral infection rate was higher in autumn and winter,which were 66.06% and 68.37% respectively and higher than 42.31% and 34.25% in spring and summer,the difference was statistically significant(P<0.05).The viral infection rates of youth (18-45 years old) and middle-aged (>45-60 years old) were 64.94% and 63.86% respectively,which were higher than 48.45%,44.92% and 55.56% in pre-elderly (>60-75 years old),elderly (>75-90 years old) and longevous elderly (>90 years old),the differences were statistically significant(P<0.05).Conclusion The respiratory virus mixed infection and IVB infection are most common in the emergency wards,moreover the viral infection situation shows the seasonal and age characteristics,but which is not affected by sex factor.

OBJECTIVE To evaluate the effect of neuromedin U(NMU) in lymph node metastasis of laryngocarcinoma and provide a new biomarker of metastasis. METHODS Samples of 120 cases of laryngocarcinoma were collected from the Otolaryngology Department of the First Affiliated Hospital of Jinzhou Medical University from 2013 to 2015. Patients were divided into two groups: metastasis group and non-metastasis group. Immunohistochemistry was performed to analyze the NMU expression in primary tumor and lymph node. An independent tissue microassay was used to analyze the relationship between NMU expression and T, N stages. RESULTS Expression of NMU in metastasis group was higher than that in non-metastasis group, NMU was positively correlated with N stages, but not with T stages. CONCLUSION The expression of NMU is higher in metastasis tissue of laryngocarcinoma, It could be used as a biomarker of lymph node metastasis of laryngocarcinoma.
