ABSTRACT
Objective@#To explore the clinical effect of cotton pads under stitches when intradermal traction with sutures is used to repair of chronic wounds.@*Methods@#From January 2009 to August 2016, 21 patients with 31 wounds were treated by continuous intradermal traction. Wound edges were sutured with 2-0 silk thread in horizontal mattress fashion, but not tied. Then small cotton pads were put under stitches to protect the skin around the wound. After that, the sutures on both sides of the wound edges were pulled to the center of the wound with a certain force. And the wound was sutured finally when the skin on both sides of the wound was closed enough.@*Results@#All of 31 wounds healed without necrosis of the skin margin and 5 cases of lacerated wound caused by silk thread healed after dressing change. The healing time was (43.24±11.46) days, and there was scarcely hypertrophic scar at the stitches. This method was compared with the previous method of protecting stitches with silicone tubes( referring to past data). There was no significant difference in the healing time between the two methods (P=0.119), and less laceration occurred under the stitches with cotton pads (P=0.046).@*Conclusions@#It is a commendable method for treating chronic wounds to put cotton pads under the stitches while tracting the wound edges with sutures. It can effectively cushion the cutting force of the silk thread, protect the traction point and facilitate the replacement of the pads.
ABSTRACT
PURPOSE: The microRNA-34 (miR-34) family is important in tumor regulation. This study aimed to investigate the association of circulating miR-34 family proteins with clinicopathological features and their prognostic value in triple-negative breast cancer (TNBC) patients. MATERIALS AND METHODS: In this cohort study, 173 TNBC patients admitted to First People's Hospital of Shunde from May 1, 2009 to April 30, 2013 were enrolled. Meanwhile, 75 age-matched healthy women volunteers were identified as healthy controls (HCs). We examined the expression of miR-34 family (miR-34a/b/c) proteins in plasma collected from TNBC patients before any treatment was performed and from age-matched HCs using qPCR methods. RESULTS: The expressions of miR-34a/34b/34c were significantly lower in TNBC patients than in HC (p<0.001, p=0.027, p<0.001, respectively). miR-34a was correlated with tumor grade (p=0.038), lymph node positive (p=0.027), distant metastasis (p=0.004), and surgery (p=0.023); miR-34b was correlated with lymph node positivity (p=0.027); and miR-34c was correlated with tumor grade (p=0.017) and distant metastasis (p<0.001). Kaplan-Meier curve analysis displayed low expression of miR-34a as associated with worse overall survival (OS) (p=0.011), as well as miR-34c low expression (p=0.002). In addition, univariate and multivariate Cox proportional hazards regression was performed, and low expression of miR-34c (p=0.011) was found to be an independent risk factor for OS, as well as tumor grade (p=0.013), lymph node positive (p=0.050), and distant metastasis (p=0.021). CONCLUSION: In conclusion, this study demonstrated reduced miR-34a/c expression is highly associated with tumor progression and indicated worse prognosis. Also, miR-34c was an independent risk factor for OS in TNBC patients.

Objective To study the role of autophagy in the curcumin (Cur) enhancing the chemosensitivity of the colorectal cancer LoVo cells to irinotecan (CPT-11). Methods The LoVo cells were separated into 4 groups:the control group,the Cur group,the CPT-11 group and the Mix group.Western blot assay was applied to determine the expression of autophagy-related protein LC3-Ⅱ and P62. LC3-Ⅱ was detected by immunofluorescence method. Transmission electron microscopy was used to detect the autophagosome. CCK-8 assay was applied to detect the cell growth inhibitory rate of LoVo cells ,which were pre-treated with autophagy inhibitor 3-MA before 24-h treatment of Cur and/or CPT-11. Western blot assay was applied to detect the expression of LC3- Ⅱ and P62. Results The mixed treatment significantly increased the expression of LC3-Ⅱwhile decreased P62 expression,compared with the Cur and CPT-11 treatments. The autophagosomes in cells of Mix group were significantly more than those in cells of the Cur and Cpt group. Pre-treatment of 3-MA significantly reduced cell growth rate in the Cur group,the Cpt group and the Mix group. Pre-treatment of 3-MA significantly decreased the expression of LC3-Ⅱ,while increased P62 expression,compared with the Mix group. Conclution Combinations of curcumin and CPT-11 could enhance the chemosensitivity of LoVo cells to CPT-11,which might be related to the activation of autophagy.
ABSTRACT
Objective To examine the effect of simvastatin treatment on Parkinson's disease rats induced by lipopolysaccharide (LPS) and its mechanism.Methods The LPS-PD model was established by injection of LPS (5 mg/mL) into the right substantia nigra compacta (SNC),and rats were randomly divided into control group,LPS-model group and simvastatin treatment group with 15 rats in each group.Rats in the simvastatin treatment group was intraperitoneally administered simvastatin (5 mg/kg) before,and daily for 14 days after surgery,while the control group and LPS-model group received same volume normal saline and LPS respectively.Ionized calcium binding adaptor molecule 1 (Iba-1)-positive cells and the expression of tyrosine hydroxylase (TH),tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) in the SNC were detected by immunohistochemistry,Western blotting and enzyme-linked immunosorbent assay,respectively.The effect of simvastatin in the PD model was also examined in behavioral tests.Results The LPS-model group exhibited typical animal PD behaviors.Compared with the control group,the LPS-model group exhibited a decreased number of DA neurons,and comparison of the intact side to reduce 81.13％ (P＜0.01) in the SNC,as well as increases in the Iba-1-positive cell number,iNOS,IL-1β and TNF-α expression (P＜0.05).These effects were inhibited by simvastatin treatment (P＜0.05).Conclusion Simvastatin mediates a protective effect on dopaminergic neurons in the SNC in the LPS-PD model,possibly by inhibiting glial cells (astrocytes and microglia) activation,and playing an anti-inflammatory role,thus improving substantia nigra function.

ABSTRACT
Objective To explore the expressions of LAT and VEGF, and the relationship between them in hepatocellular carcinoma (HCC). Methods The expressions of LAT protein and VEGF protein in SO HCC, 30cirrhosis and 10 normal tissues were assessed by immunohistochemical method. Results The expressions of LAT and VEGF in cancer tissues, cirrhosis tissues, normal tissues were significantly different. The expression of LAT in HCC tissues was stronger than that in cirrhosis, but the expression of VEGF in cirrhosis was stronger than that in HCC tissues. Conclusion The expression of LAT was not closely associated with the expression of VEGF in HCC. The abnormal expressions of LAT and VEGF were closely associated with the development of HCC. They may play important roles in development of HCC.

ABSTRACT
Objective To explore applied characteristics of the prolene hernia system(PHS) in inguinal hernioplasty, and management during and after operation, and long-term effect of this kind of hemioplasty in aged patients. Methods 69 aged patients using PHS were followed and analyzed retrospectively. Results Tension-free inguinal hernioplasty with the PHS were performed in 69 aged patients of groin hernia. Operative time ranged from 45min to 160min. Post-operatively, 3 patients developed gentle scrotal swelling, and 20 patients had been adminis- tered anodyne for pain of incision, and 12 cases experienced retention of urine, 1 case developed pneumonia, and 2 cases oeeurred incisional infection and gore. 68 cases of them recovered daily life about 2 to 3 weeks after operation. During follow-up period from 6 months to 77 months,there was no recurrence of inguinal hernia and no pain in in-guinal region, but 2 patients feel discomfort sporadically. Conclusion The PHS strengthens the myopectineal orifice and seals up-area of it,so the system is especially preferred in treating aged patients of groin hernias who have some defectsof anatomic structure in inguinal region. The local anaesthesia is also suitable for this kind of hernioplasty in aged patients.
ABSTRACT
To systematically evaluate the importance of protein synthesis in ischemic preconditioning (PC)-induced ischemic tolerance (IT), temporary middle cerebral artery occlusion (MCAO)by Longa (20 min) was used for PC (ischemic precondioning). Twenty-four hours of reperfusion was allowed after PC and before permanent MCAO to establish ischemic tolerance (IT) to compare with non-PC (sham-operated) rats (n=5 for each group). Infarct size and neurological deficits were measured 24 h after PMCAO. Samples of brain were taken for the determination of HSP70 expression by Western blot analysis. The effects of the protein synthesis inhibitor cycloheximide administered just before PC or administered long after PC but just before PMCAO on IT were also determined (n=5 for each group). Our results showed that hemispheric infarct was significantly reduced (P＜0.01) only if PC was performed after 24 h, and PC significantly (P＜0.05) reduced neurological deficits (similar to reductions in infarct size). Cycloheximide eliminated ischemic PC-induced IT effects on both brain injury and neurological deficits if administered before PC but not if administered long after PC but before PMCAO. PC produced no brain injury but did increase HSP70 protein 24 h after PC. Cycloheximide eliminated that effect. The results suggest that PC is a powerful inducer of ischemic brain tolerance as reflected by the preservation of brain tissue and motor function. PC induces IT that is dependent on de novo protein synthesis.
ABSTRACT
To examine the ability of intrastriatal gene transfer of vascular endothelial growth factor 165 mediated by adenoviral vector to rescue dopaminergic neurons in a rat model of Parkinson's disease (PD), we constructed recombinant replication-deficent adenoviral vectors carrying the gene of VEGF165 (Ad-VEGF), and injected Ad-VEGF (or Ad-LacZ and PBS as controls) into the striatum of rats 7 days after the lesion by 6-hydroxydopamine. The rat rotational behavior analysis and tyrosine hydroxylase (TH) immunohistochemistry were performed to assess the change of dopaminergic neurons. Our results showed that the rats receiving Ad-VEGF injection displayed a significant improvement in apomorphine-induced rotational behavior and a significant preservation of TH-positive neurons and fibers compared with control animals. It is concluded that intrastriatal gene transfer by Ad-VEGF may rescue the dopaminergic neurons from degeneration in a rat model of PD.

ABSTRACT
Objective To summarize our experience on laparoscopic splenectomy with amputation of the secondary spleen pedicle. Methods From September 2006 to May 2007, laparoscopic splenectomy with amputation of the secondary spleen pedicle was performed on 13 patients, including 5 cases of traumatic spleen rupture, 2 idiopathic thrombocytopenic purpura, and 6 hypersplenism. Results All the operations were completed under a laparoscope without using hand-assisted procedures. The intraoperative blood loss was 50-800 ml (mean, 350 ml), and the operation time was 150-300 min (mean, 210 min). No complications occurred during and after the operation. The average postoperative hospital stay was 5-9 d (mean, 7.5 d). The patients were followed up for 1-6 months, during which all the patients had normal platelet count. Conclusions Laparoscopic splenectomy with amputation of the secondary spleen pedicle is a feasible, minimally invasive, safe and low-cost procedure.
