BACKGROUNDSingle incision laparoscopic colectomy has been performed in recent years, and has been shown to be feasible and safe. This study was to assess the feasibility of single incision laparoscopic right hemicolectomy and to compare the differences in different approaches.

METHODSThis retrospective study included eighteen patients with carcinoma of caecum and ascending colon, undergoing single incision laparoscopic right hemicolectomy. This study also compared single incision laparoscopic right hemicolectomy using different approaches: (1) single incision multiport, (2) single access port and (3) glove port.

RESULTSThere was no statistical difference in surgical outcomes. Concerning the surgeon's satisfaction toward three methods, overcrowding and durability were similar but the single incision multiport was associated with the highest gas-leak and the "glove" port was associated with poor durability. However, the method of single incision multiport has the lowest average cost of the special trocar or port in each operation. The operative time and blood loss of the operations in this study were comparable to previous publications.

CONCLUSIONThere was no significant difference between different approaches of single incision laparoscopic right hemicolectomy for colonic cancer in right side colon.

Objective To evaluate a fast-hardening strontium-calcium phosphate scaffold using a two-step reaction in room temperature.Methods The original powder phase consisted of tetracalcium phosphate (TTCP),dicalcium phosphate anhydrous (DCPA) and strontium hydrogen phosphate (DSPA).The liquid phase consisted of 20wt％ citric acid and 12wt％ polyvinylpyrrolidone K-30.Groups were designed as Sr-0,Sr-5,Sr-10,and Sr-20,according to the molar ratios of Sr/(Sr + Ca) being 0,5％,10％,and 20％ in the powder phase,respectively.The ratio 0.5 mL/g in the liquid to solid phase was used for mixing.After the scaffold was prepared,its setting time,compression strength,phase composition and structural morphology,ions release and pH value of the substrates were analyzed.Results Addition of citric acid accelerated the setting reaction.Acceptable setting time was achieved by optimizing composition of the original powder and liquid phases.On the other hand,the compression strength,phase composition and structural morphology were not affected by addition of strontium.In addition,calcium and strontium ions were detected in the substrates,without any significant change in the pH value.Conclusion This two-step reaction can be used to prepare a fast hardening strontium-calcium phosphate scaffold in room temperature.

BACKGROUND: In Shenzhen, the Emergency Medical Service (EMS) system has been in service since 1997. This study aims to examine the operation of Shenzhen 120 EMS center and to identify the reasons of calling EMS. METHODS: In this retrospective quantitative descriptive study, the data from the Shenzhen 120 EMS registry in 2011 were analyzed. RESULTS: Shenzhen 120 EMS center is a communication command center. When the number of 120 are dialed, it is forwarded to the closest appropriate hospital for ambulance dispatch. In 2011, the Shenzhen 120 EMS center received 153160 ambulance calls, with an average of 420 calls per day. Calling emergency services was mainly due to traffic accidents. Trauma and other acute diseases constituted a majority of ambulance transports. The adult patients aged 15–60 years are the principal users of EMS. There are no recognized 'paramedic' doctors and nurses. The pre-hospital emergency service is under the operation of emergency departments of hospitals. Shenzhen at present does not have specialized pre-hospital training for doctors and nurses in post-trauma management. Moreover, specialized pre-hospital training, financial support, and public health education on proper use of EMS should be emphasized. CONCLUSION: The Shenzhen 120 EMS center has its own epidemiology characteristics. Traumatic injury and traffic accident are the main reasons for calling ambulance service. In-depth study emphasizing the distribution and characteristics of trauma patients is crucial to the future development of EMS.

Background/Aims: Data on treatment efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) for chronic hepatitis C virus (HCV) infection in Asian patients with severe renal impairment are limited. This study aimed to study the treatment and side effects of GLE/PIB in these patients infected with non-1 genotype (GT) HCV. Methods: We prospectively recruited patients with Child’s A cirrhosis and eGFR <30 mL/min/1.73 m2 in Hong Kong and Taiwan during 2017–2018 to receive GLE/PIB treatment. Results: Twenty-one patients (GT2, n=7; GT3, n=6; and GT6, n=8) received GLE/PIB for 11.2±1.8 weeks. All except one were treatment-naïve. GLE/PIB was initiated in 16 patients while on dialysis (seven on peritoneal dialysis [PD] and nine on hemodialysis) and in five patients before dialysis. One patient died of PD-related peritonitis during treatment and two were lost to follow up. The SVR12 rate in the remaining 18 patients was 100%. All patients achieved undetectable levels at 4-, 12-, 24- and 48-week after treatment. Patients with deranged alanine aminotransferase showed normalization after 4 weeks and the response was sustained for 48 weeks. No significant adverse event was observed. Conclusions GLE/PIB treatment was associated with high efficacy and tolerability in HCV-infected patients with severe renal impairment.

A proportion of patients experience acute or even prolonged cognitive impairment after surgery, a condition known as postoperative cognitive dysfunction (POCD). It is characterized by impairment in different cognitive domains and neuroinflammation has been implicated as one of the inciting factors as strategies targeting inflammation tend to improve cognitive performance. Siegesbeckia Orientails L. (S. Orientails) is a common Chinese medicinal herb used for managing chronic inflammatory diseases. We investigated if pretreatment with S. Orientails before surgery confers any neuroprotective effects in postoperative animals in terms of reducing inflammation and mitigating cognitive impairment. Three-month-old male C57BL/6N mice were fed different doses of S. Orientails extract for 14 days before they underwent a laparotomy. After cognitive testing they were sacrificed on postoperative day (POD) 3. Our results showed that animals with extract pretreatment demonstrated memory improvement in a dose-dependent manner compared with control. Further, evidence for the attenuation of systemic and neuroinflammation was found in the pretreated animals, along with the inhibition of inflammatory pathways and significantly reduced tau phosphorylation in the hippocampus. Taken together, these results demonstrated a neuroprotective effect of S. Orientails in postoperative animals, indicating a therapeutic potential of S. Orientails in minimizing POCD and the possibility of utilizing this traditional Chinese medicine perioperatively.
