Objective:To investigate the effectiveness of autologous bilateral auricular concha cartilage-modified scaffolds in rhinoplasty.Methods:Retrospectively, 219 patients aged (28.7±5.5) years, 8 males and 211 females, who underwent rhinoplasty at the An Beili Medical Beauty Clinic in Shimen County, Changde City, Hunan Province, from January 2020 to January 2022, were included. Every patient consented to apply modified scaffolds of autologous bilateral auricular concha cartilage for rhinoplasty; 157 received primary rhinoplasty and 62 underwent secondary rhinoplasty repair. To construct the nasal tip morphology, bilateral auricular concha cartilage was excised, symmetrically divided and aligned sutures to form nasal columellar support grafts and anti-tip rotation grafts. Thermoplastic splints and tape were used to fix the dorsum of the nose, and tumescent sponges to fill the nasal cavity. Prophylactic antibiotics were routinely administered after surgery for 48 hours, and depending on how well the wound healed, the stitches were taken out 8 to 10 days later.Results:A local infiltration anesthetic was used throughout the procedure on all 219 patients. The majority of patients had a willow-shaped prosthesis constructed for the dorsum of their noses. A total of 145 patients had silicone prostheses, and 74 patients had expanded polytetrafluoroethylene prostheses. The mean operating duration was (72.92±13.26) minutes. Within 8 to 10 days after surgery, all patients had their sutures taken out, the surgical incisions healed properly, and all 219 patients were satisfied with their nasal appearance in the immediate postoperative period. The nasal tip height was elevated by an average of (4.7±0.5) mm, and the nasal length was extended by an average of (5.7±0.6) mm over the mean follow-up of (14±2) months. Among 219 patients, 96.8% (212/219) of the patients expressed satisfaction with the form of their noses. The postoperative nasal shape, with its naturally elevated nasal dorsum, rounded tip profile, and pronounced tip-defining point, complied with the natural aesthetic criteria. Three patients experienced a chronic nasal infection following surgery, while the remaining four experienced postoperative tip-down rotation.Conclusions:Using bilateral auricular concha cartilage, the tip cartilage modified scaffolding provides a better nasal appearance and tip mobility after rhinoplasty for the patients.

Objective To estimate the diagnostic value of cytology, DNA-ICM(DNA-image cytometry),cytology combined with DNA-ICM for pancreatic malignancy,and to explore the cut-off value for DNA-ICM. Methods Patients with suspicious pancreatic malignancy were retrospectively identified. In total,145 EUS-FNA specimens acquired from 140 separate patients were examined by cytology and DNA-ICM. Diagnostic values among cytology, DNA-ICM and the combination of the techniques in detecting pancreatic malignancy were compared. Results Compared with cytology, DNA-ICM had a lower sensitivity (63.0% VS 82.4%)and accuracy(69.7% VS 85.5%). After combining the techniques, the diagnostic value for pancreatic malignancy significantly improved compared with that by cytology(0.941 VS 0.912, P=0.007 0)or DNA-ICM only(0.941 VS 0.815, P<0.000 1). By using the Youden index, the cut-off value for DNA-ICM to detect pancreatic malignancy was one cell with DI(DNA index)≥2.5. Notably,with this standard, the sensitivity and accuracy of DNA-ICM significantly increased to 72.3% and 77.2%, and those of the combined techniques increased to 91.6% and 93.1%, respectively. Conclusion Automated DNA-ICM is an objective and effective method for pancreatic malignancy. Although DNA-ICM has a lower diagnostic value than that of conventional cytology, an improved value was obtained after combining the techniques.

OBJECTIVETo examine the expression of cytokine-induced apoptosis inhibitor1 (CIAPIN1) in gastric cancer and normal mucosa tissues, and to investigate its effects on migration and invasion of gastric cancer cells.
METHODSImmunohistochemistry was used to detect CIAPIN1 expression in 15 samples of normal gastric mucosa tissues, 148 samples of gastric cancer tissues (42 of non-metastasis gastric cancer tissues without other organs or lymph node metastasis, 106 of metastasis gastric cancer tissues with lymph node metastasis), and 37 samples of gastric cancer lymph node metastasis tissues. Association of CIAPIN1 expression with clinicopathological characteristics of gastric cancer was analyzed by Chi-square test. SGC-7901 cell lines of high CIAPIN1 expression and low CIAPIN1 expression were established. Transwell assay was applied to detect the invasion and migration of CIAPIN1-regulated gastric cancer cells.
RESULTSPositive rate of CIAPIN1 expression in gastric cancer tissues was lower than that in normal gastric mucosa tissues (41.2% vs. 86.7%, P=0.0008), and in metastasis gastric cancer tissues was also lower than that in non-metastasis gastric cancer tissues (34.9% vs. 71.4%, P=0.0000). Furthermore, the positive rate of CIAPIN1 expression was closely related to the TNM staging of gastric cancer (TNM stage I(, II( and III( were 55.0%, 53.5% and 24.4%, respectively, P=0.0037). But there was no significant difference of positive expressive rate between metastatic gastric cancer tissues and metastatic lymph node tissues(34.9% vs. 21.6%, P=0.3700). Transwell assay showed that up-regulated CIAPIN1 expression would significantly reduce, while down-regulated CIAPIN1 expression would significantly promote the invasion and migration of SGC-7901 cells (all P<0.05).
CONCLUSIONPositive rate of CIAPIN1 expression is low in gastric cancer tissues and shows inhibition of invasion and migration of gastric cancer cells.

Objective To evaluate the safety and efficacy of percutaneous transluminal angioplasty (PTA) in treating Budd-Chiari syndrome (BCS) and to analyze the long-term follow-up results. Methods From October 1998 to May 2008,98 BCS patients (inferior vena cava obstruction,n = 34 ; hepatic vein obstruction, n = 22; combined obstruction, n = 42) who accepted PTA treatment successfully were investigated. The changes of clinical manifestations and liver function post-operation were observed; the long term survival rate was evaluated. Results Only two patients were complicated with transhepatic puncture tract bleeding, the prognosis was good after emergency operation. Sixty patients presented with low extremities edema, which was fully subsided after PTA.Of eighty-eight ascites patients, ascites disappeared in eighty patients after operation, and in the other eight patients combined with oral diuretic treatment post-operation. The median Rotterdam prognostic score of one month post-operation and the last follow-up time point was 0. 11 and 0. 09, significantly lowered than pre-operation (1.12). The difference was statistical significance (P=0. 000). At 1, 3, 5 years postoperative, the cumulative vessel patency rates were 96%, 94% and 94% respectively, and the cumulative survival rates were 94%, 91% and 87%. Conclusions Treating BCS with PTA has a high success rate, a good safety and a long-term survival rate.

Objective To evaluate the therapeutic efficacy and safety of transjugular intrahepatic portosystemic shunt (TIPS) for the treatment of portal hypertension of patients with hepatocellular carcinoma.Methods Ninety-five portal hypertension patients with hepatic carcinoma were enrolled.TIPS was performed in 63 patients and the other 32 patients received support medical care.The data referred to survival time of the 95 patients after treatment was collected by follow-up visit.The informations about success rate of TIPS,hepatic encephalopathy,rebleeding and causes of death were assessed.The Kaplan-Meier method was used to compare the survival time between two groups.The association of survival time with Child-Pugh classification and model for end-stage liver disease (MELD) score was analyzed.Results The success rate of TIPS was 97.8% with reduction of mean portal vein pressure of 13.6 cmH2O(1 cmH2O=0.098 kPa).The incidence of hepatic encephalopathy was 20.6% and rebleeding was 26.3% six months after TIPS treatment.Fifty-six patients treated with TIPS died at the end of follow-up.Twelve of which were died of variceal bleeding complicated with portal hypertension.The median survival time of TIPS group (3.67 months) was significantly longer than that of control group (1 month). Moreover, the median survival time in patients with low MELD score (≤13) was significantly longer than that in those with high MELD seore (>13, x2=4.71,P=0.03). Whereas the median survival time was decreasing from Child-Pugh A to C(x2=15.6,P=0.00). Conclusions TIPS is one of effective and safe therapeutic methods to control portal hypertension. However, liver function is an important factor for selcetion of TIPS.

Objective To evaluate the expression of KAII (CD82) gene inhibited by small interfering RNA (siRNA) in human pancreatic cancer cell line T3. Methods Four sequences of siRNA including A, B,C, D were designed, which were based on the KAI1 gene sequence using online RNA interfering designing software and lentivirus vector was built. Then they were used to transfect T3 cells by liposome 2000 and virus titer was determined. Empty vector containing siRNAd1 lentivrus particle ( MOI =5) was also used to infect T3 cells. The expression of CD82 mRNA was detected by real-time PCR. Results The expression of CD82 mRNA in normal control group, empty vector group, A group, B group, C group, D group were 1. 398 ±0.242,1. 311±0.048, 0. 664 + 0. 093, 0. 345 ± 0. 032, 0. 641 ± 0. 049 and 0. 147 ± 0. 049, respectively, the difference between the expression of CD82 mRNA in empty vector group and that of A, B, C, D groups was significant (P<0.01 ). Conclusions RNAi was able to inhibit the expression of KAI1 gene CD82 in human pancreatic cancer cell line T3.

OBJECTIVETo establish attenuated Salmonella typhimurium producing Helicobacter pylori (H. pylori) urease subunit B (UreB) and determine whether it could be used as an oral vaccine against H. pylori.
METHODSH. pylori (SS1 strain) UreB gene fragment amplified by PCR was cloned into the prokaryotic expression vector pTC01 after sequencing, and then transformed into attenuated Salmonella typhimurium SL3261 to acquire SL3261/pTC01-UreB. The expression of H. pylori UreB in SL3261 was detected by Western blot. Twelve weeks after oral immunization of mice, antibody responses were evaluated using serum and intestinal fluid by ELISA assay. Interferon-gamma (IFN-gamma) and interleukin-10 (IL-10) in the supernatant of spleen cells culture were also assessed by ELISA. In vitro stability of pTC01-UreB plasmid in SL3261 was confirmed by growing in Luria Broth (LB) medium to 80 generations.
RESULTSThe UreB gene fragment amplified by PCR was consistent with the sequence of the H. pylori UreB as evidenced by sequence analysis. Enzyme digestion revealed that the correct pTC01-UreB was obtained. Western blot showed that a 61kDa protein was expressed in SL3261/pTC01-UreB, which could be recognized by anti-H. pylori UreB antiserum. After 80 generations of continuous culture, the recombinant plasmid pTC01-UreB was stable in SL3261 and had no obvious toxicity. Multiple oral immunizations with SL3261/pTC01-UreB could significantly induce H. pylori-specific mucosal IgA response as well as serum IgG response. Moreover, there were significant increases of IFN-gamma and IL-10 in the SL3261/pTC01-UreB group. Finally, no obvious side effects for mice and no change in gastric inflammation were observed.
CONCLUSIONAttenuated Salmonella typhimurium expressing H. pylori UreB may be used as oral vaccine against H. pylori infection.

OBJECTIVETo study the characteristics of host immune response against human gastric carcinoma of different histological types.
METHODSThe expression of 24 families of T cell receptor beta chain variable region (TCRVbeta) and cytokine profiles in isolated CD4(+) and CD8(+) subsets, as well as the cytokine profiles in purified epithelial cells from the tumor tissue and the residual benign tissue of patients with gastric carcinoma, was detected by a highly sensitive radioactivity labeled semi-quantitative RT-PCR technique.
RESULTSThe number of expanded T cell clones in CD8(+) subset from tumor tissue of the intestinal-type carcinoma was larger than that of diffuse-type (P = 0.046). The mRNA levels of IL-6, IL-8 in CD8(+) T subset, as well as the level of TNF-alpha in CD4(+) T subset from the tumor tissue of the diffuse type (0.61 +/- 0.29, 0.56 +/- 0.22, 0.09 +/- 0.03) were significantly higher than that from the residual benign tissue (0.14 +/- 0.05, 0.27 +/- 0.09, 0.04 +/- 0.02; P = 0.028, P = 0.043, P = 0.046). However, the mRNA level of IL-8 in CD8(+) subset and epithelial tumor cells of the intestinal-type (0.57 +/- 0.25, 0.27 +/- 0.07) was significantly higher than that from the residual benign tissue (0.21 +/- 0.07, 0.14 +/- 0.06; P = 0.028, P = 0.028).
CONCLUSIONSThe characteristics of host immune response against tumor are different between intestinal-type and diffuse-type gastric carcinoma. Both fewer expanded T cell clones and more suppressive cytokines suggest a more suppressive immune status in the local tumor lesion of diffuse-type than in the intestinal-type of the gastric carcinoma.
