Objective To investigate the common etiologies,sports and learning situation of children in Nantong with short stature,and discuss the relationship between the two. Methods Did a retrospective analysis of 108 cases of children with short stature in Nantong University′s affiliated hospital since January 2012. Through detailed past illnesses, physical examination, laboratory tests, diagnose short stature and clarify the cause. Did a questionnaire to these children with short stature about sports and learning situation. Use statistical methods like multivariate Logis-tic regression analysis and link analysis to analyze sports and learning situation of children in Nantong with short sta-ture and find the relation with the etiology. According to the principle of group matching,the control group elected representative of 108 children. Results In 108 cases, 61 cases were because of growth hormone deficiency (GHD), accounting for 56. 5% ; 47 cases were because of non-growth hormone deficiency (NGHD), accounting for 43. 5% . Logistic regression analysis showed that participation in physical exercise was a protective factor. Rest-less anxiety and inattention were as risk factors,and these make a lot(P < 0. 001, OR = 7. 483, 95% CI = 2. 620 ~21. 374). There was no significant relation between common cause and sports, learning situation ( P > 0. 05). Conclusion Various types of sports (basketball, badminton, running, cycling) are protective factors for children of short stature. Restless anxiety and inattention are risk factors for children with short stature. Whether there is growth hormone deficiency or not, children with short stature should increase the right exercise as much as possible and avoid or reduce exposure to these risk factors.

Objective To evaluate the diagnostic accuracy of ultrasound miniature probe(UMP)examination in tumor invasion(T staging) and local lymphatic node metastasis(N staging) for colorectal carcinoma. Methods Preoperative UMP examinations(12 MHz) were performed on 53 patients with colorectal carcinoma undergoing surgeries.The diagnosis accuracy of UMP examination in T and N staging was determined by comparison of the results of operation exploration and histopathologic findings. Results The accuracy in T staging for colorectal carcinoma was 86% with UMP examination,and that for early stage colorectal carcinoma was 100%.The accuracy,sensitivity and specificity in N staging for colorectal carcinoma were 81%,77%,and 84%,respectively with UMP examination. Conclusion UMP examination works well in determining T stage of colorectal carcinoma,especially for early stage colorectal carcinoma and those with tumor stenosis.

AIM: To make evaluation on fluid resuscitation with either hypertonic saline(HS) or dextran 40(Dx) on pancreatic microthrombi and dysfunction of microcirculation in rats with severe acute pancreatitis(SAP).METHODS: SD rats were allocated into 4 groups randomly,ie.SAP group,HS group,Dx group,which respectively received normal saline(NS,4 mL/kg),HS(4 mL/kg),Dx(4 mL/kg) for 2 h by the tail intravenous injection consecutively after being made as SAP animal models,and operate sham group(OS).12 h after the operation,all animals were blooded to assess the serum amylase levels,plasma D-dimer,von Willebrand factor and GMP-140 levels.The amount of ascites was measured and the samples of the pancreas were collected for pathologic examination under light microscopy as well as transmission electron microscope.The numbers of pancreatic microthrombi were also counted with microscopy.RESULTS:(1) 12 h later when the rats were sacrificed,the survival rate in SAP group was the lowest,significantly lower than that in the 2 fluid resuscitation groups(P

AIM:To observe the effect of captopril on the genesis and development of gastric cancer , and to explore its clinical treatment feasibility for gastric cancer .METHODS:The human gastric cancer cell line AGS was used to establish a tumor model in nude mice , and the model mice were randomly divided into 3 groups: positive control ( 5-fluorouracil) group, normal control (saline) group and experimental (captopril) group.After intraperitoneal injection or intragastric administration of the drugs , the tumor growth curve was determined , and the tumor tissues were also sampled to detect the expression of Ki-67, STAT3, Bax and Bcl-2 by real-time quantitative PCR and immunohistochemistry .The apop-tosis was detected by TUNEL +DAPI staining .RESULTS: The tumor growth curve showed that the tumor model in the nude mice was successfully established .The tumor volumes among groups showed significantly different after 14 d growth. The increase in the tumor volume in normal control group was significantly faster than that in the other two groups , and that in positive control group was the slowest .The expression of Bax in captopril group increased , and the expression of STAT3, Ki-67 and Bcl-2 was reduced as compared with normal control group and positive control group .Compared with normal con-trol group, the apoptotic rate increased significantly , and the protein expression of p-STAT3 and STAT3 decreased obviously in positive control group and captopril group .CONCLUSION:With better feasibility , angiotensin-converting enzyme in-hibitor captopril has a significant effect on treating gastric cancer in the AGS nude mouse model by regulating the expression of STAT3, Bax, Bcl-2 and Ki-67 to accelerate the apoptosis of cancer cells , thus inhibiting tumor growth .

Objective The epidemiology of Acinetobacter baumannii isolates from bloodstream infections,their antibiotic resistance profiles and virulence-associated factors were studied.Methods A total of 90 isolates from 17 hospitals were collected from the patients with bloodstream infections during July 2013 and July 2014.Vitek-2 Compact system was used for identification of the strains and antibiotic susceptibility testing.The epidemiology was studied by pulsed-field gelectrophoresis(PFGE).Drug-resistant genes and associated virulence genes were amplified by PCR.Results According to antimicrobial susceptibility testing,75 isolates are multi-drug resistant Acinetobacter baumannii.PFGE results showed that 75 multi-drug resistant Acinetobacter baumannii isolates belonged to eight clone types(A to H),with the A (n=51)and B (n=14)clone being the dominant PFGE clone types.Different clone isolates spread in different hospitals.Most of the hospitals were given priority to with clone A.Clone A only maintaining high sensitive rate to cefoperazone/sulbactam、amikacin and tigecycline.Virulence gene abaI,cusE,ompA,bap,bfms detection rates are 93.3% (84/90),92.2% (83/90),100.0% (90/90),84.4% (76/90),92.2% (83/90),respectively.There were 7 mucoid isolates,which are all multi-drug resistant Acinetobacter baumannii,all belong to clone B and all associated virulence genes can be detected.Conclusions The dominant clone type of multi-drug resistant Acinetobacter baumannii from bloodstream infections is clone A.The abaI-,bap-and bfms-positive strains are associated with a higher incidence of antibiotic resistance in most types of antimicrobials.The acquisition of mucous type may indicate the emergence of virulent strains,which should be paid attention to during clinical treatment.

Objective To evaluate one-stage arthroscopic reconstruction of anterior crueiate ligament (ACL)and posterior cruciate ligament(PCL)using Achilles tendon-bone allografts. Methods From July 2000 to February 2005.we treated 15 patients(11 males and 4 females)whose ACL and PCL were ruptured at one knee but the eontralateral knee was intact.Their associated meniscus injuries were treated arthroscopically according to established procedures prior to ligament reconstruction.Thirty Achilles tendon-bone allografts were used to reconstruct torn ACL and PCL in 15 knees at one stage.Reconstruction of both ligaments was performed at subacute or chronic phase(>3 to 8 weeks)in 12 casses,and at acute phase in 3 cases(<3 weeks).All knees were graded pre-and postoperatively using the International Knee Documentation Committee(IKDC)and Lysholm scoring systems.At follow-up,functions were evaluated for all patients and compared with those of the contralateral healthy knee. Results All patients were followed up for a minimum of 3 years(mean,38 months).Preoperatively,the IKDC ratings showed all the injured knees were severely abnormal.At final postoperative f0Uow-up,9 knees received a normal rating,5 a nearly normal one and 1 an abnormal one.The differences in Lysholm score were statistically significant (t=15.660,P<0.05)between pre-and postoperative analyses.The most noticeable postoperative complication was a short localized fever coupled with arthroedema in 1 case. Conclusions Achilles tendon-bone allograft offers an alternative for simultaneous arthroseopic reconstruction of ACL and PCL.However,problems inherent in allograft tissues entail further investigation to ensure future application.
