The paper introduced the organization culture building of a private hospital, in creating the Aikang hospital as your home culture and Aikang values for building a harmonious workplace for the hospital. The management system reform features the separation between regulations and management,building of the supporting system and operating system, for better quality of care with advanced management practice. The social rewards feature great efforts in supporting the disadvantageous population, and undertaking public health service and charity activities. These care and love to the community help the hospital to fulfill its social responsibilities.

Objective To study the prevalence of thrombocytosis in patients with non-small-cell lung cancer (NSCLC) and its correlation with clinicopathological features.Methods 156 patients with advanced NSCLC were retrospectively analyzed.The platelets degree between the groups with different sex,age,smoking,histological type of advanced NSCLC was compared and analyzed statistically.The relationship between the platelet count and chemotherapy effects was analyzed.Single analysis and Cox regression analysis were used for TTP and OS.Results Compared with the healthy persons,Plt significantly elevated in group with advanced NSCLC (36.5 ％,57/156 vs 5.0 ％,5/100) (P ＜ 0.01),and thrombocytosis group responded poorly to chemotherapy (22.8 ％,13/57 vs 39.4 ％,39/99) (P ＜ 0.05).The TTP (3.0 months vs 5.2 months) and OS (11.2 months vs 14.2 months) of Plt elevated group were significantly shorter than those of normal group.Conclusion Thrombocytosis is closely related to progress and metastasis of advanced NSCLC.Platelet count can be used as an assistant index in the prognosis judgment of patients with advanced NSCLC.

Objective To discover the mutations of rare thalassemia genes by sequencing of α and β-globin genes,to understand the frequency of rare mutations and to enrich thalassemia gene mutation spectrum in Chinese population.Methods For the cases of phenotype and genotype inconsistent,the 1st generation of sequencing was performed for α or β-globin gene coding region sequence analysis.Results A total of 102 patients with rare thalassemia gene mutations were found by sequencing,including 79 cases of β-thalassemia with 35 kinds of mutant types,and 23 cases of α-thalassemia with 11 kinds of mutant types.Conclusion The thalassemia gene sequencing could reveal rare mutations in genes,identify the genotype of patients,provide important support for prenatal diagnosis of rare thalassemia families,and reduce the missing rate and birth rate of children with thalassemia.

ObjectivesTo explore the roles of mean corpuscular volume(MCV),mean corpuscular hemoglobin(MCH) and hemoglobin A2 (HbA2) in the laboratory screening of thalassemia,and to find optimal screening modality for different conditions.Methods From September 2008 to May 2011,1384 subjects underwent thalassemia screening at Department of Obstertrics andGynecology of Nanfang Hospital.Of them,1036 cases were diagnosed with thalassemia (408 α-thalassemia,608 β-thalassemia,and 20 αβ compound thalassemia,thalassemia group) and 348 without thalassemia,non-thalassemia group.All subjects were screened respectively for MCV,MCH and HbA2.Analyses were performed in all subjects to assess the sensitivity,specificity,positive predictive value,negative predictive value and diagnostic accuracy respectively associated with MCV,MCH and HbA2 alone,combination of MCV and MCH,and combination of MCV,MCH and HbA2.Results( 1 ) In the thalassemia group,the sensitivity of MCV alone was 92.9％ (379/408) for α thalassemia,99.3％ (604/608) for β thalassemia and 100.0％(20/20) for αβ compound thalassemia.In the non-thalassemia group,the specificity of MCV alone was 75.0％ (261/348).(2) In the thalassemia group,the sensitivity of MCH alone was 92.9％ (379/408) in α thalassemia,99.0％ (602/608) in β thalassemia and 100.0％ (20/20) in αβ compound thalassemia.In the non-thalassemia group,the specificity of MCH alone was 72.7 ％ (253/348).(3) The sensitivity of Hb A2 alone was 67.4％ (275/408) for α thalassemia,97.5％ (593/608) for 3 thalassemia,and 100％ (20/20) for α3 compound thalassemia while it's specificity was 72.4％ (252/348) in the non-thalassemia group.(4)With positive indexes of MCV,MCH and MCV + MCH,when HbA2 ＞ 3.5％ it had a high value in [β-thalassemia screening,but when HbA2 ＜ 2.5％ it had little value in α-thalassemia screening.(5) As a single marker,MCV and MCH had better sensitivity,specificity,positive predictive value,negative predictive value and diagnosis accuracy than HbA2.MCV + MCH was the best for overall screening,but for [β thalassemia screening,MCV + MCH + HbA2 was the best.ConclusionsMCV and MCH are suitable for epidemic screening in a large population,physical examination and premarital check-up.Hb electrophoresis andthalassemiagenediagnosisarerecommendedforsubjectswithpositiveMCVandMCH indexes.Diagnoses of α and β-thalassemia gene are recommended for pregnant women with positive MCV and MCH indexes.

Objective To discuss the influence of preoperative family purge care for the quality of life of patients with long type of congenital Hirschsprung′s disease (HD) who had enterocolitis history in neonatal period. Preoperative family purge care, which can shorten the HD postoperative treatment, improve the quality of life. Methods A total of 40 cases of patients with long type of congenital HD who had enterocolitis history in neonatal period received 1-stage radical preoperative by family phone call. Nineteen cases from January 2010 to February 2013 were as normal group and 21 cases from March 2013 to April 2016 were as improved group. Routine family purge nursing care 3-6 months were used in both the groups, while the combined nursing care of expanding anus were used in the improved group in addition. Evaluated the effects of postoperative observation indicates: the first defecation time, length of hospital stay, time needed for expanding anus, patency rate of defecation and not patency rate in 9-12 days, need enema intervention to assist defecate rate after postoperative 1 year, the recurrence of enterocolitis at 1-3 years after operation. Results The first defecation time, length of hospital stay, time needed for expanding anus were (39.15±8.23) h, (7.89±0.82)d, (5.17±0.98) min in normal group, (23.79± 7.54) h, (7.10± 0.29) d, (3.15±0.73) min in improved group, and there were significant differences between two groups (t=6.13, 5.46, 15.54, all P<0.01). The patency rate of defecation and not patency rate in 9-12 days were 12/19, 7/19 in normal group, 100.00%(21/21), 0 in improved group, and there were significant differences between two groups (χ2=9.38, P<0.01). The intervention rate of no need for enema, occasionally enema, often enema were 2/19, 12/19, 5/19 in normal group, 76.19%(16/21), 23.81%(5/21), 0 in improved group, and there were significant differences between two groups (χ2=18.25, P<0.01). There was no significant difference in the recurrence of enterocolitis at 1, 2, 3 years after operation between two groups (χ2=2.33, P>0.05). Conclusions Patient with long type of congenital HD who had enterocolitis history in neonatal period neonatal period,received family enema and expanding anus in 3- 6 months before 1-stage radical preoperative can shorten the postoperative HD treatment, improve the quality of life.

Objective To investigate the characteristics of blood donors’psychological activity,take reasonable intervention measures to improve the success rate of blood donation recruitment and the ratio of repeated blood donation.Methods The data of blood donors’psychological activity was collected by distributing questionnaires randomly,and the psychological characteristics and worries were analysed.Results In terms of the blood donation purpose,there were 62.73% of the blood donors who donate blood for the first time and take the“utility psychological”as the principal thing.There were 76.01% of the blood donors who donate blood repeatedly and take the“dedication psychological”as the principal thing.In terms of wor-ries,there was 72.69% of the blood donors who donate blood for the first time and take the“safety of blood donation”as the principal thing.There was 77.91% of the blood donors who donate blood repeatedly and take the “service quality of blood donation”as the principal thing.Conclusion The success rate of blood donation recruitment and the ratio of repeated blood donation could be effectively improved by attaching importance to the psychological needs and worries of blood do-nors,by taking different psychological intervention measures strategies for different kinds of blood donors,and by meeting their needs and eliminating their worries.

Objective To summarize the geographical distribution,phenotype and genotype data of 206 thalassemia families underwent prenatal diagnosis to provide information for clinical genetic counseling and avoid the birth of severe thalassemia children.MethodsTotally,206 thalassemia families were collected from Southern Medical University Nanfang Hospital from January 2008 to December 2009.Genomic DNA was extracted from peripheral blood,villus,amniotic fluid or cord blood from the couples or the fetuses.Gap-polymerase chain reaction (gap-PCR) and reverse dot blot (RDB) technology were used to detect the common α and β-thalassemia mutations.DNA sequencing was used to detect the rare mutations.Follow-up visit were done half a year after the fetuses were born. Results The 206 thalassemia families came from 12 provinces and areas across China,including Heilongjiang province.Mutations detected in α-thalassemia families included --SEA/,-α3.7/,-α4.2/,αCS α/ and αQS α/,which were all included in the testing kit. While there were 4 kinds of β-thalassemia mutations,Gγ+ (A γδβ)0,-28(A→C),CD54-58(-TATGGGCAACCCT) and CD37(G→A),could not be identified with routine testing kit. The 57 α-thalassemia families consisted of 11(19.3％) severe thalassemia,induding 8 Bart's hydrops syndrome and 3 Hb H disease,26(45.6％) heterozygote and 20(35.1％) normal infants,and the 149 β-thalassemia majors families consisted of 28 (18.8％) severe thalassemia,82(55.0％) heterozygote and 39 (26.2％) normal infants.Among the β-thalassemia heterozygotes,there was one 13-trisomy.Follow-up visit found that babies with Bart ' s hydrops syndrome (n =8),Hb H disease (n =3),β-thalassemia majors (n =28) and β thalassemia heterozygote combined with 13-trisomy(n=1) were aborted.Conclusions Thalassemia was found in some north area other than south of China,which should be paid more attention by clinicians.Gap-PCR and PCR-RDB technology are effective measures for thalassemia prenatal diagnosis in identifying major thalassemia fetuses before their birth,thus reduce the birth rate of thalassemia baby.But missed diagnosis might exist during the screening,so it is necessary to perform DNA sequencing on those patients with positive symptoms and negative common genetic diagnostic results.At the same time,prenatal diagnosis of chromosomal disorders should not be neglected for high-risk families.

Objectiev To explore the use of different nebulizer to establish mice model that have airway eosinophilic inflam -mation without airway hyperresponsiveness .Methods Female BALB/c mice were obtained and divided randomly into 3 groups:eo-sinophilic airway inflammation group ( experimental group ) , asthma group, and control group .Mice were immunized with ovalbumin ( OVA) .The experiment group and asthma group were challenged with an aerosol of 1% w/v OVA using a PARI TIA and PARI LC STAR nebulizer on day 28, 29, 30, respectively.The control mice were received saline sensitization and challenge .Airway respon-siveness was measured .Cell different counts in bronchial alveolus lavage fluid ( BALF) were performed and a pathologist performed histopathological evaluation of the trachea and lung .Results Airway responsiveness in the experimental group was not significantly different compared with the normal saline ( NS) group but was significantly different compared with the asthma group .Eosinophils in BALF were increased significantly in experimental group compared with the NS group , and significant difference was observed between experimental group and asthma group .The intensity of airway inflammation in experimental group was milder than that in the asthma model .Conclusions We established an eosinophilic bronchitis mice model without hyperresponsiveness successfully .Our model es-tablished a foundation for the further research in airway hyperresponsiveness .

Objective To explore the expressions of Toll-like receptors (TLRs) 2 and 4 in mouse skin during early immune responses against Sporothrix.Methods A total of 60 BALB/c mice were randomly and equally divided into an experimental group and a control group to be intracutaneously injected with Sporothrix conidium suspensions at a concentration of 1 × 106 cfu/ml and sodium chloride physiological solution respectively.Five mice were sacrificed before the injection,and at 6,12,24,48,and 96 hours after the injection in each group,blood samples were obtained from the mice before sacrifice,and skin tissue specimens were resected from the area around the injection sites after sacrifice.Realtime fluorescence-based quantitative PCR was performed to quantify the mRNA expressions of TLR2 and TLR4,and immunohistochemical staining to observe the protein expressions of TLR2 and TLR4 in mouse skin specimens.Enzymelinked immunosorbent assay (ELISA) was conducted to determine the levels of interleukin 12 (IL-12) and tumor necrosis factor α (TNFα) in serum samples from the mice.Results After injection of Sporothrix conidium suspensions,the mRNA expression level of TLR2 gradually increased and peaked at 24 hours,which was 18.8 times that in the control group at 6 hours and 34 times at 24 hours.In addition,the mRNA expression level of TLR4 in the experiment group reached a peak,and was 56.7 times that in the control group at 6 hours after injection,then gradually decreased and reached the nadir at 96 hours.As immunohistochemical staining revealed,TLR2 and TLR4 were apparently expressed in both keratinocytes and macrophages in skin specimens from the experimental group,but not obviously in those from the control group.No significant differences were observed between the experimental group and control group in serum levels of IL-12 or TNF-α at any of the sampling time points.Conclusion TLR2 and TLR4 may play a favoring role in immunological defense by participating in the recognition of Sporothrix by keratinocytes and macrophages in mouse skin.

AIM: The purpose of this study was to observe the morphological features of neuroendocrine cells(NECs),their proliferation and apoptosis in ovarian epithelial tumors,and to discuss their biological and clinical significance.METHODS: 79 specimens of ovarian epithelial tumor samples were collected,of them 20 benign,18 boderline,41 milignant tumors,and 22 normal ovaries were investigated immunohistochemically.Chromogranin A was used to detect NECs and their proliferation and apoptosis were examined by double-label staining of chromogranin A and Ki67 or TUNEL.RESULTS: The positive rate of CgA,distribution and staining intensity in ovarian epithelial tumors were higher than those in normal ovary.NECs showed various shapes with neuronoid protuberances stretching to the neighboring cells or basement membrane.Occasionally,they might touch together.No TUNEL positive coexpression in all NECs was observed by double-label staining,but some NECs were coexpressed with Ki67.CONCLUSION: NECs of ovarian epithelial tumors like cancer cells showed a proliferation,but no apoptosis.Their secretion might promote their neighboring non-NECs to proliferate and prevent them from apoptosis.
