Objective To investigate the protective effect of gonadotropin releasing hormone agonist on ovarian function in patients with early stage cervical cancer.Methods80 cases ofadmitted patients with early stage cervical cancerfrom January 2015 to January 2016 in Yinzhou Second Hospital were selected, were randomly divided to observation group and control group.Patients in the observation group were retained ovarian resection, while giving the gonadotropin releasing hormone (GnRH) agonist treatment, the control group patients only with reservation of ovary resection and compared between the two groups before and after chemotherapy in patients with basal follicle stimulation hormone (bFSH) levels, serum anti Mullerian tube hormone (AMH) level, basic estrogen (bE2) levels, and the basal antral follicle number (bafc).ResultsThere were no significant differences in two groups of chemotherapy in patients with anterior bFSH and bE2 level, after chemotherapy, the observation group patients bFSH and bE2 level was significantly lower than that in control group (P<0.05) and chemotherapy after bFSH level of two groups of patients were higher than that in the chemotherapy before.bE2 levels were lower than those before chemotherapy (P<0.05);chemotherapy the number of patients in the two groups of AMH level and bafc without significant difference, after chemotherapy, the observation group AMH levels and bafc number were significantly higher than those of the control group (P<0.05) and chemotherapy after two groups of patients with AMH levels and bafc number lower than the chemotherapy before (P<0.05).ConclusionGnRH agonists can effectively protect the early cervical cancer patients with radical resection of ovarian reserve and ovarian reserve function, clinical application is worthy of further promotion.

Objective To compare the clinical outcomes and safety of synchronous vs staged bilateral total hip arthroplasty (THA).Methods Fifty-eight cases (116 hip joints) undergone bilateral THA from January 2008 to January 2010 were reviewed retrospectively.Follow-up period was postoperative 2 years,including synchronous bilateral THA in 29 cases (synchronous group) and staged bilateral THA in 29 cases (staged group).The two patient groups were compared in aspects of total operation time,total amount of blood loss,total amount of blood transfusion,duration and cost of hospitalization,postoperative discrepancy in bilateral leg length,preoperative and postoperative function score and perioperative complications.Results During the follow-up,no complications of incision infection,deep vein thrombosis and prothesis dislocation or loosening were noted.And postoperative delirium symptoms occurred only in four cases (three in synchronous group and one in staged group).There were no statistical differences between synchronous group and staged group in aspects of total operating time [(117.9 ± 23.8) minutes vs (124.1 ± 18.8) minutes],total amount of blood loss [338.1 ml (180-720 ml) vs 303.9 ml (200-600 rnl)],total amount of blood transfusion [227.6 ml (0-800 ml) vs 189.7 ml (0-400 ml)],postoperative function score.However,differences of the following data were considered statistical significance between synchronous group and staged group:expense of hospitalization [9.5 ten thousand yuan (7.0-11.3 ten thousand yuan) vs 10.5 ten thousand yuan (8.8-11.0 ten thousand yuan)],length of hospitalization [(12.1 ±3.2) days vs (20.1 ±3.5) days],postoperative discrepancy in bilateral leg length [(0.11 ± 0.22) cm vs (0.42 ± 0.44) cm].Conclusions Synchronous bilateral THA is safe and feasible as far as the patients' physical condition is allowed,perioperative management is rational and physicians have mature surgical techniques.Moreover,it gains advantage over staged bilateral THA considering cost of hospitalization,length of hospitalization and postoperative discrepancy in bilateral leg.

ObjectiveTo explore the clinical features,etiological factors,diagnosis and treatments in children with hemophagocytic syndromes (HPS).MethodsA retrospective study was carried out to analyze etiological factors,clinical symptoms and sighs,laboratory findings and outcomes of 32 children with HPS in our hospital.Results( 1 ) Etiological factors:virus infection cases accounted for 75.0％ (24/32),in which Epstein-Barr virus infection cases were predominant,making up to 68.8％ (22/32) ; (2) Main clinical features:included persistent fever,hepatosplenomegaly,lymphadenopathy; ( 3 ) Characteristic laboratory findings:included decrease of three lines or two lines of peripheral blood cells,hyperferrttinemia,abnormal liver function and coagulation function,hypertriglycerdema and decreased fibrinogen,hemophagocytosis in bone marrow,high soluble interleukin-2 receptor level,decreased natural killer cell activity.(4) Treatments and outcomes:twenty-four(24/32) virus infection cases received antivirus and high dose of immunoglobulin treatment.Twenty-two cases were treated with glucocorticoid and cyclophosphamide,resulting in 11 cases improvement,5 cases with complete remission,2 cases giving up and 4 death.The other 10 cases were treated under the guide of HLH-2004 protocol treatmemt with 4 cases improved and 6 cases with complete remission.Conclusion HPS is mainly triggered by infections,especially Epstein-Barr virus infection.Serum ferrifin,interleukin-2 receptor level and natural killer cell activity are biomarkers of the disease,so that they should be monitored during the progress of chemotherapy.HLH-2004 protocol is a good guide for the treatment of this disease.

Objective To analyze the etiology and clinical characteristics of infectious mononucleosis-like syndrome (IMLS).Methods Eighty-seven children with IMLS in a hospital from January 2006 to September 2013 were per-formed pathogenic detection,then clinical features were summarized and analyzed.Results The top 5 pathogens in IMLS were Mycoplasma pneumoniae (MP,n=20 ),cytomegalovirus (CMV,n=13),simplex herpes virus(HSV, n=11),Chlamydia (CP,n=11),and parvovirus B19 (Hpv B19,n=9 ),clinical manifestations of all kinds of dis-eases were similar,but the occurrence rates were slightly different.MP infection were mainly fever,hepatospleno-megaly,and lymphadenopathy,and most were associated with respiratory complications(including laryngitis,bron-chitis,and pneumonia),CMV infection were also showed fever and hepatosplenomegaly,but the latter was more ob-vious;rubella patients didn’t appear skin rash,but the other symptoms were obvious.Conclusion Etiologies of in-fectious mononucleosis-like syndrome are varied,MP infection is most common,the next is CMV.Pathogens should be ascertained to provide theoretical basis of treatment.

Objective To evaluate the effects of simulated family nursing on the cognitive function and activity of daily living in patients with Alzheimer's disease.Methods Sixty-eight patients with Alzheimer's disease were assigned to routine nursing condition and simulated family nursing condition.The patients were assessed with Mini-Mental State Examination (MMSE) and Activity of Daily Living Scale (ADL) before intervention,and 3 months and 6 months after intervention.Results Compared with the control group,the patients' cognitive function (t=2.31,P=0.026) and activity of daily living (t=2.59,P=0.012) were improved significantly in the experimental group.Conclusion The simulated family nursing can improve the cognitive function and activity of daily living in patients with Alzheimer's disease.

Objective To explore the impact on survivors's health and to determine the risk factors involved in the typhoon in order to investigate the characteristics of traumatic symptoms of casualties in the aftermath of the Saomai Typhoon sweeping over the rural area of Zhejiang province in 2006. Method A cluster sampling study was carried out and a total of 389 survivors were assessed. Data were analyzed by univariate and multivariate Logistic analysis to clarify the characteristics and the risk factors of getting traumatize. Results Of 389, there were 113 (29.1% ) victims suffered from a variety of injuries mainly crush trauma (24.4 % ) and wounded by hard object (23.1% ). Moreover, the combined injuries accounted for 9.2%. The risk factors causing injuries in the residential area were the building collapse, glass fragments from broken windows, flying debris as well as fall from high place. Condclusions Outdoor activity and the crumbled building are the leading causes for injuries during the sweeping of typhoon. Meanwhile, we should make more effort to publicize the precautions against typhoon to the local residents.

Objective The aim of this study was to evaluate the outcomes of auditory perception skills after cochlear implantation in children with malformed inner ear and compare them with a group of congenitally deaf chil ‐dren implantees with a normal inner ear .Methods 21 children with inner ear malformation were retrospective stud‐ied .There were 9 cases with large vestibular aqueduct syndrome (LVAS) ,7 with Mondini abnormality ,5 with com‐mon cavity .The postoperative outcomes of these 21 cases were compared with 21 cases with normal inner ear struc‐ture .The outcomes of all the children after the surgery in 1 year were studied using the soundfield test in frequency ranging 0 .5 to 4 kHz and the auditory perception skills ,and the auditory perception skills consisted of natural envi‐ronmental sound recognition ,consonants recognition ,vowels recognition ,numeral recognition ,tone recognition , monosyllabe recognition ,disyllabe recognition ,trisyllabe recognition ,short sentences recognition ,selective hearing recognition .Results The results of soundfield test and auditory perception skills after cochlear implantation in 9 children with LVAS and 6 with Mondini abnormality had no significant difference (P > 0 .05) comparing with the control cases .Postoperative thresholds in soundfield test were 50 ~ 75 dB HL for 1 case with severe Mondini abnor‐mality ,the mean value of hearing ability score was 70 .5% ,and less than the results of control cases .Postoperative mean thresholds in soundfield test were 65 .26 ± 5 .13 dB HL for 5 cases with common cavity ,the hearing ability score was less than the results of control cases (P< 0 .05) .Conclusion The effect of rehabilitation had no difference between the children with LVAS and the cases with normal inner structure after cochlear implantation ,but was poo‐rer in children with severe Mondini abnormality and common cavity .It was necessary to evaluate the degree of mal‐formation of inner ear structure before cochlear implantation .

Objective To study the epidemic characteristics and disease spectrum of Epstein-Barr virus (EBV) infected children in Zhongshan region, Guangdong province. Methods Clinical data from the children with positive EBV-DNA detected by real-time lfuorescent quantitative PCR between 2011 and 2013 was retrospectively analyzed. Results A total of 409 cases were detected with EBV-DNA positive from 3402 cases, with a total positive rate 12%, and the positive rate is 8.1%in 2011, 10.4% in 2012, 19.5% in 2013, there were significant differences among positive rate (χ2=6804.00, P<0.05). There was no statistically signiifcant difference in the positive rate of EBV-DNA between different gender (χ2=0.239, P>0.05) and different age groups (χ2=136.96, P<0.05). The positive rate of pre-school group is the highest. EBV infection can cause multiple system diseases. The most common disease caused by EBV infection was infectious mononucleosis (61.6%), followed by respiratory tract infection (26.7%), neck lymphadenitis (3.4%), idiopathic thrombocytopenic purpura (2.4%), etc. Among the 409 cases of EBV infection, the concurrent other pathogen speciifc IgM positive cases as MP-IgM positive (n=79), CP-IgM positive (n=47), Parvovirus B19-IgM positive (n=20), HSV-IgM positive (n=11), CMV-IgM positive (n=10), and RV-IgM positive (n=4) were found. Conclusions Infectious mononucleosis is the leading disease in children infected by EBV in Zhongshan region, the annual positive rate is increasing. Multiple pathogen speciifc IgM may be detected positive in children with EBV infection, which should be interpreted in combination with clinical status.

Objective To explore the clinical characteristics, treatment and prognosis of pediatric patients with bronchiec-tasis caused by Mycoplasma pneumonia (MP) and Chlamydia pneumonia (CP). Methods The clinical data from 27 MP and CP pneumonia pediatric patients with bronchiectasis suggested by the high resolution CT were retrospectively analyzed. Results The morbility rate of bronchiectasis caused by MP and CP pneumonia is 0.56%. The mean age of these patients was 75.4 ± 52.7 months. Among them, 27 cases (100%) had cough, 19 cases (70.4%) had fever, 10 cases (37%) had respiratory distress and 20 cases had lung auscultation. Sixteen cases were MP-IgM positive, 5 cases (18.5%) were CP-IgM positive and 6 cases (22.2%) were positive of both. Eight cases were combined with other pathogens infections, in which 6 cases were bacterial infections. The imaging ifndings showed diffuse bronchiectasis in 13 cases (48.1%) and local bronchiectasis in14 cases (51.9%). The bronchoscopy found endothelium in-lfammation, mucosal swelling, partial erosion and follicular hyperplasia in 16 cases (66.7%), the formation of short column sputum bolt in 5 cases (20.8%), in which 1 case had plastic bronchitis. All patients were treated with macrolides antibiotics, 10 cases (37%) combined with methylprednisolone, 3 cases (11.1%) combined with immunoglobulin and 20 cases (74%) combined with other anti-biotics. The average length of hospitalization was 12±4.3 days. The bronchiectasis sign disappeared within 4 months in 23 cases (92%). Two cases (8%) still had bronchiectasis after 9 to 15 months, with the recurrent pneumonia. Conclusions MP and CP pneumonia can lead to acute bronchiectasis. Most of patients are recoverable with effective treatment.
