Objective To analyze the postoperative complications in aged patients receiving pancreaticoduodenectomy. Methods Pancreaticoduodenectomy was employed for the treatment of 52 aged patients. Of the 52 patients with a mean age of 70.5(65-76), 32 were male and 20 female. Postoperative pathological examination confirmed that 24 patients suffered from Vater,s ampullary and duodenal cancers, 16 from pancreatic carcinoma and 12 from cholangiocarcinoma. Results The mortality was 7.7%. Severe complications included bleeding (upper gastrointestinal tract or abdominal cavity),MOF, ARDS, postsurgical gastroparasis syndrome(PGS), mental disorder, pancreaticogastrostomy leak and biliary-enteric anastomotic leak et al. Conclusion MOF is the main lethal complication. Incidence of PGS and mental disorder is high.

The INK4a-ARF locus is located on CDKN2A point in human chromosome 9p21 and is known to encode two functionally distinct tumor-suppressor genes p16INK4a (MTS1/CDKN2/INK4a/p16) and p14ARF, have been shown to play significant roles in cell-cycle regulation in cancer. p16 is encoded by the exon 1a-exon 2-exon 3 transcript and functions as a negative regulator of the cell cycle through its inhibition of cyclin-dependent kinases (CDKs) 4 and 6 and subsequent blockage of the cyclindependent phosphorylation of pRB . Thus, loss of p16 function leads to deregulation of pRB's suppressive block of the G1-to-S transition and cell proliferation. In contrast, p14ARF is encoded by the exon 1?-exon 2 transcript and acts upstream of p53. Biochemical evidence has demonstrated that p14ARF physically interacts with human double minute 2 (HDM2) gene product and consequently stabilizes p53, leading to G1 cell-cycle arrest. Overall, somatic mutation of the INK4a/ARF tumor suppressor locus, resulting in functionally deficient p16 and possibly p14ARF proteins, seems to be a prevalent event in the development of oesophagus carcinoma.

Aim A cerebrospinal fluid (CSF) sample from patient was subjected to microscopy two Angiostrongylus Cantonensis of developing female and male were found and identifed for the first time in the CSF of the patient at the same time. It is the first case in Liaoning province China.

Objective To investigate the drug sensitivity of cardia tumors in vitro by ATP-TCA, and to provide basis of clinic chemotherapy. Methods 42 cardia tumors were tested by ATP-TCA to determine and assess the drug sensitivity of 8 common chemotherapeutics. Correlation analysis was done between the clinical classification and the drug sensitivity. Results The drug sensitivity had significant difference among cardia tumors. From high to low, it was ADM>MMC>PTX> 5-Fu>HCT =VP16>CDDP>IFO, Sensitive degree were 50.00 %, 35.45 %, 31.25 %, 23.53 %, 10.53 %, 10.53 %, 7.69 %, 5 %. Sensitivity of the same drug in different pathologic stages had no significant difference. Conclusion ATP-TCA can play a guiding role in individual chemotherapy for human cardia cancer.

Objective To explore the early diagnostic value of quantitative sensory testing (QST) in diabetes with peripheral neuropathy (PNP).Methods The nerve conduction velocity (NCV) and QST were examined in 46 diabetic patients, and their results were compared. Results The abnormal ratio of NCV in 46 patients was 72.8%. 32 cases (69.6%) were diagnosed as diabetes with PNP. While using QST, the abnormal ratio was 91.3%. 40 cases (86.9%) were diagnosed as diabetes with PNP. There was a significant difference between two methods ( P

Objective To evaluate the effect of Butylphthalide Soft Capsules on cerebral hemodynamics in patients with acute cerebral infarction by 64 slice spiral CT perfusion(CTP) imaging .Methods The patients with acute cerebral hemisphere infarction within 6 h after the onset were selected and randomly divided into the experimental group and the control group .Conventional plain CT and CTP were performed in both groups .In addition to the routine treatment the experimental group was orally administrated Butylphthalide Soft Capsules 0 .2 g ,once per 6 h .The CTP examination was performed again after 12 h .Results The CTP exami-nation showed that the cerebral perfusion in experimental group was improved in the ischemic marginal region ,the cerebral blood flow(CBF) and cerebral blood volume(CBV) were increased compared with before treatment ,the mean transit time(MTT) and the time to peak( TTP) were shortened compared with the before treatment .Conclusion Butylphthalide Soft Capsules can significantly improve the CBV of ischemic penumbra region and brain ischemic hypoperfusion .

Objective To explore the relationship of serum leptin concentration,body mass index (BMI) and esophageal squamous cell carcinoma.Methods Blood samples were collected from 47 patients with esophageal squamous cell carcinoma and 20 healthy controls in Shanxi Cancer Hospital.Serum leptin was measured by ELISA.Results Serum leptin concentration in patients group was significantly higher than control group[(13.09±5.94) ng/ml vs (7.58±4.16) ng/ml,(t =3.76,P =0.001)].In 47 patients,BMI,albumin and lymphocytes were (25.20±3.14) kg/m2,(43.58±2.15) g/L and (2.02±0.55)×109/L,respectively.The serum leptin concentration of all patients (47 cases) were positive correlation with BMI (r =0.561,P =0.006),not with blood albumin and lymphocytes (r =0.206,P =0.242; r =0.122,P =0.412).Multiple logistic regressionanalysis reveal statistically significant association between serum leptin and esophageal squamous cell carcinoma incidence (OR =1.442,95 ％ CI 1.094-1.848,P=0.09).Conclusion Higher serum leptin levels seem to represent an additional and independent risk factor for esophageal squamous cell carcinoma.

[Summary] This paper reported a case of 4-year-old boy suffered with medial meniscus tear treated by arthroscopic repair in our hospital.After the boy injured his knee , plaster was applied for 4 weeks.Without any symptomatic progress , he was hospitalized with the diagnosis of medial meniscus tear .We performed arthroscopic meniscus repair , using 4.0-mm arthroscopy.At 3-month follow-up, the boy could full-bearing walk with no pain or discomfort , with a range of motion of 0°-135°.The post-operational MRI at the fourth month showed preliminary healing of repaired meniscus .We believe that regular arthroscopic instruments can accomplish meniscus repair in young children .

Objective To explore the clinical significance and the impact on prognosis of blood micrometastasis in the patients with pN0 esophageal squamous cell carcinoma. Methods Total RNA was extracted with TRIzol and mRNA was transcribed reversely into cDNA. RT-PCR was used to detect MMP-7 mRNA and hTERT mRNA in blood. △△Ct sample values were calculated with post-operative follow-up of 3 month, 6 month, 12 month. Results Statistical results suggested that blood micrometastasis was related to differentiation grade and pTNM staging (P=0.000, P=0.000 respectively), but not to age, sex, length of turnout (P0.05). Follow-up results suggested that the degree of invasion and tumor metastasis (recurrence) was no correlation; follow-up to 6 month and 12 month, tumor metastasis (recurrence) was associated with blood micrometastasis, and follow-up to 12 month, compared with the tumor metastasis (recurrence) probability of blood micrometastasis-positive patients and negative patients, the former was as 6.44 times as the latter. (OR=6.440, 95 % CI 1.547-26.822). Conclusion Blood micrometastasis testing is of great significance to early diagnosis and prognosis judgment in pN0 esophageal squamous cell carcinoma patients.
