Objective To compare clinical outcome between 3D and 2D laparoscopic nephron sparing surgery for renal tumor. Methods Ninety patients who underwent laparoscopic nephron sparing surgery for renal tumor were collected. The patients were divided into 3D laparoscopic nephron sparing surgery (observation group) and traditional laparoscopic nephron sparing surgery (control group) according to the surgery method with 45 cases in each group. The operating time, renal warm ischemia time, blood loss, postoperative length of stay, hospitalization cost and rate of postoperative complications were compared between 2 groups. Results The operating time and renal warm ischemia time in observation group were significantly shorter than those in control group:(80.3 ± 10.7) min vs. (94.6 ± 18.5) min and (17.8 ± 3.1) min vs. (23.4 ± 4.7) min, and there were statistical differences (P<0.01 or 0.05). There were no statistical differences in blood loss, postoperative length of stay, hospitalization cost and rate of postoperative complications between 2 groups (P>0.05). Conclusions Compared with the traditional 2D laparoscopic technology, 3D laparoscopic technology has obvious advantage in spatial location and the sense of depth. To some extent, 3D laparoscopy reduces the operation difficulty, and shortens the operative time and renal warm ischemia time.

Objective To observe the clinical efficacy of yang-supplementing thread-embedding (acupoint embedded with catgut soaked in Shenfu injection) in treating shoulder-hand syndrome after cerebral stroke. Method Totally 120 patients were randomized into a treatment group and a control group, 60 cases in each group. The treatment group was intervened by acupoint thread-embedding, while the control group was by conventional acupuncture. The changes of symptoms, joint range of motion (ROM), pain, and Fugl-Meyer Assessment (FMA), and general therapeutic efficacy were observed after 30 d treatment. Result The total effective rate was 95.0% in the treatment group versus 85.0% in the control group, and the difference was statistically significant (P<0.05). Conclusion Yang-supplementing thread-embedding and conventional acupuncture both can mitigate pain induced by shoulder-hand syndrome, increase the range of motion, and significantly improve the upper-limb motor function, while the effect of yang-supplementing thread-embedding is superior to that of conventional acupuncture.

Objective:To observe the effect of combining scalp acupuncture with hyperbaric oxygen on serum homocysteine and highly-sensitive c-reactive protein levels and functional recovery after cerebral infarction.Methods:A total of 101 survivors of cerebral infarction were divided randomly into a scalp acupuncture group ( n=33), a hyperbaric oxygen group ( n=34) and a combined treatment group ( n=34). All received routine treatment plus the appropriate supplementary treatment once a day for 10 days. The subjects were evaluated before the experiment as well as 10 and 90 days afterward. The National Institutes of Health′s stroke scale (NIHSS) was used to quantify neurological deficits and the Barthel Index quantified ability in the activities of daily living. Ninety days after the treatment, modified Rankin scale scores were also assigned. The levels of serum homocysteine (Hcy) and highly-sensitive c-reactive protein (hs-CRP) before and after 10 days of treatment were also compared among the 3 groups. Results:The average NIHSS and Barthel Index scores of all three groups had improved significantly after 10 days of treatment and the improvements persisted at the follow-up 3 months later. Both results were significantly better in the combined treatment group than in the scalp acupuncture group at the 90-day follow-up evaluation. The average Rankin score of the combined treatment group was lower at the last follow-up. Compared with before the intervention, the average Hcy of the scalp acupuncture group, the average hs-CRP of the hyperbaric oxygen group, as well as the average Hcy and hs-CRP of the combined treatment group were significantly lower after 10 days of treatment. Compared with the scalp acupuncture group, the average Hcy [(11.68±2.6) μmol/L] of the combined treatment group was significantly lower after the 10 days of treatment.Conclusions:Supplementing scalp acupuncture with hyperbaric oxygen therapy improves the long-term outcomes of cerebral infarction, reducing the level of serum Hcy.

Objective:To investigate the current application of colonoscopy at hospitals in China.Methods:From November 2019 to January 2020, an online questionnaire survey was conducted among gastroenterologists and colonoscopists in hospitals of different levels. The contents of questionnaire survey included basic information of colonoscopy at the respondent′s hospital, protocols and patient education of bowel preparation, implementation of colonoscopy quality control, and colonoscopists′ understanding of polypectomy techniques and post-polypectomy follow-up.Results:A total of 236 valid questionnaires were collected, involving 187 hospitals, and 143 (76.5%) had an annual operation capacity of more than 5 000 cases. In terms of bowel preparation, split-dosed polyethylene glycol electrolyte powder (PEG) was the most commonly used (60.4%, 113/187) and the most common volume of PEG was 3 L (67.4%, 126/187). Verbal (90.9%, 170/187) and written (79.7%, 149/187) instructions were given more often than other methods for patient education of bowel preparation. Antifoaming agent was routinely used in 124 (66.3%) hospitals. In terms of quality control, only 11.5% (20/174) hospitals implemented all four measures. In terms of polypectomy techniques, 98.1% (203/207) colonoscopists chose hot snare polypectomy or endoscopic mucosal resection for lesions of diameter>1 cm, while options varied for lesions of diameter<1 cm. The interval of follow-up after polypectomy recommended by colonoscopists was shorter than that by guidelines.Conclusion:Several problems are found in the survey in the application of colonoscopy in China, i. e., patient education of bowel preparation is not diversified; quality control of colonoscopy still needs to be strengthened; polypectomy techniques and follow-up after polypectomy need to be further standardized.
