Con-clusion CT is the first choice in the diagnosis of pancreatic trauma. Master the CT symptom and make right diag-nosis, which were important to clinical operation.

Objective To investigate the clinical curative effect of dorsal nerve fasciocutaneous flap in the treatment of children fingertip defect.Methods A total of 20 children (26 fingers)with fingertip defect were chosen as the research objects,and all of them were given the dorsal nerve fasciocutaneous flap surgery within the same finger.The sensory recovery,color,shape and function of the fingers were ob-served.Results All the 26 fingers were survived,and the survival rate was 100%.There were 8 cases of ambient blood circulation crisis 1 to 2 days after the surgery which were eliminated with corresponding treatment.Postoperative follow-up results showed that the sensory re-covery of the skin flap was S2 ~S3 6 months after surgery,and the two-point discrimination (2-PD)was 8 ~14 mm;the sensory recovery of the skin flap was S3 ~S3 +(19 fingers of S3 and 7 fingers of S3 +)12 months after surgery,and the two-point discrimination (2-PD)was 6 ~10 mm;the sensory recovery of the skin flap was S3 +~S4 (20 fingers of S3 +and 6 fingers of S4)12 months after surgery,and the two-point discrimination (2-PD)was 5 ~8 mm.Up to then,the finger shape and color of patients was similar with normal finger,the skin graft donor site was smooth without scar contracture,the finger joint function recovered well,and the distal interphalangeal joint function were normal.Conclusion Treatment of dorsal nerve fasciocutaneous flap repair for children fingertip defect has good clinical effect and it is wor-thy of clinical application.

Objective To investigate the 19 and 21 exon mutation status of the epidermal growth factor receptor(EGFR) gene in the patients with lung adenocarcinoma and its distribution differences among different groups .Methods The related samples in 109 cases of lung adenocarcinoma were collected in our hospital during 2013-2014 .The 19 and 21 exons of EGFR gene were detected by adopting the ARMS‐PCR method .Results Among 119 cases ,19 and 21 exons mutations were found in 56 cases(51 .38% ) ,in which 24 cases (22 .02% ) were in exon 19 and 33 cases (30 .28% ) were in exon 21 .59 cases were male with 19 cases(32 .20% ) of mutant type and 50 cases were female with 37 cases (74 .00% ) of mutant type;64 cases were ≥ 60 years old with 34 cases (53 .13% ) of mutant type ,45 cases were <60 years old with 22 cases(48 .89% ) of mutant type;33 male cases were smoking with 7 cases(21 .21% ) of mutant type and 25 male cases were non‐smoking with 12 cases (48 .00% ) of mutant type .Conclusion The 19 and 21 exon mutation rate of EGFR gene in the patients with lung adenocarcinoma is higher in this area ,the 21 exon mutation rate is slightly higher than that of 19 exon;the mutation type and mutation rate are correlated with sex and smoking history ,but have no correlation with age .

Objective To investigate the main pathogenic factors of fetal distress and its complications and to reduce perinatal mortality. Methods Two hundred and ten records and pathological slides in autopsy due to fetal distress were reviewed. Results Cord problem was the first cause of fetal distress followed by placental and maternal factors. Most fetal distress were caused by multi-factors. Among 210 cases,meconium aspirative syndrome was found in 170 cases (81%),amniotic fluid aspiration 36 cases (17.1%) and hypoxic syndrome 4 cases (1.9%). There were 59 cases complicated with aspirative pneumonia including 48 cases of meconium aspirative pneumonia and 11 with amniotic fluid aspirative pneumonia. The main complications were hypoxia-ischemic encephalopathy(HIE)(153 cases),diffused pulmonary hemorrhage(68 cases) and fatal malformations (27cases). Conclusion Fetal distress increases perinatal mortality when complicated with HIE,diffused pulmonary hemorrhage,pulmonary infection or fatal malformation

Objective To analyze the clinical value of ovarian surgery in the treatment of primary ovarian mucinous carcinoma patients with fertility requirements.Methods 51 cases with fertility requirements with primary ovarian mucinous carcinoma who received surgical treatment were analyzed.The postoperative serum follicle stimulating hormone (FSH) and luteinizing hormone (LH),estradiol (E-2),anti Mullerian hormone (AMH) were deteced.The patients were followed up for 3 years,the survival rate and fertility were observed.Results Of 51 patients underwent surgery,postoperative 7d,14d,the FSH,LH levels in serum were higher than before operation (F=24.198,21.554,all P<0.05),E-2,AMH,PSV values were lower than before operation (F=24.407,35.028,11.064,all P<0.05).During the follow-up period to June 2015,there were 4 patients died of tumor recurrence,2 patients were lost to follow-up,45 patients survived,the survival rate was 88.23%.Of 45 patients survived,41 patients were normal menstrual cycle,menstruation,menstrual cycle 26-31 d,average (28.2±2.2)d;4 patients with irregular menstruation.Married women in the follow-up of 44 cases,including 28 patients with successful pregnancy,the pregnancy rate was 63.64%,there were 4 cases of spontaneous abortion,pregnancy in 3 patients because of abortion,pregnancy examination found 17 cases of abnormal pregnancy,4 cases of premature delivery.Conclusion In patients with primary ovarian mucinous carcinoma,it is feasible to use fertility preserving function,and the pregnancy rate is high,but the follow-up and monitoring should be strengthened to avoid the bad prognosis.
