The Comparative Study of Open and Laparoscopic Partial Hepatectomy in 64 Cases of Patients

Objective: A comparative study between two methods of open and laparoscopic partial hepatectomy. Method: 64 cases of patients with partial hepatectomy were choosing from our hospital from January 2014 to December 2014. Two groups were assigned according to the principle of random allocation of the open group and laparoscopic group, respectively and were observed its operation index, post-operative recovery indicators and other indicators. Results: Abdominal incision length, intra-operative bleeding volume, post-operative advanced liquid time, and hospitalization time were significantly better in Laparoscopic than laparotomy group (p < 0.05). There was no significant difference in the operation time and complications between the open and laparoscopic group (p > 0.05). Conclusion: Laparoscopic partial hepatectomy is obviously superior to open liver resection where it is worth promoting in clinical practice

Comparative study of CT-guided radiofrequency and alcohol ablation in the treatment of primary hyperhidrosis

ObjectiveThis study compared the efficacy and complications of percutaneous radiofrequency ablation with anhydrous alcohol ablation of sympathetic nerves in treating hyperhidrosis of the head and palms.MethodsA retrospective analysis was conducted on 54 patients with primary hyperhidrosis in our department from June 2018 to June 2021, divided into a radiofrequency ablation group (30 cases) and an anhydrous alcohol ablation group (24 cases). Treatment outcomes were compared by analyzing the number of CT scans, effectiveness, and complications.ResultsIn the radiofrequency group, symptoms of bilateral hyperhidrosis significantly improved in 24 patients, with an 80% postoperative satisfaction rate. In the alcohol ablation group, symptoms significantly improved in 19 patients postoperatively, with a 79.2% satisfaction rate. There was no statistically significant difference in effectiveness or complications between the two groups (all P > 0.05). The number of CT scans in the radiofrequency group was 4.60 ± 0.56 and 6.08 ± 0.28 in the alcohol group, showing a statistically significant difference (P < 0.05).ConclusionThis study concluded that both percutaneous radiofrequency ablation and alcohol ablation are effective methods for hyperhidrosis treatment, with similar effectiveness and complication rates, but the radiofrequency ablation group required fewer CT scans

Highly controllable and reliable ultra-thin Parylene deposition

Thanks to the excellent barrier property and fabrication accessibility, Parylene has been actively used in the microelectromechanical system. An ultra-thin Parylene film with thickness smaller than 100 nm is usually required to precisely tune the surface property of substrate or protect the functional unit. The commercially available regular Parylene deposition is a dimer mass determined chemical vapor deposition process with a high output (i.e. a low deposition precision in term of thickness control), around 1.6 μm/g (the ratio of film thickness to the loaded dimer mass) for the machine in the author’s lab. Therefore, it is hard to controllably and reliably prepare a Parylene film with thickness smaller than 100 nm, which requires a dimer mass less than 62.5 mg. This paper reported a method to prepare ultra-thin Parylene films with the nominal thickness down to 1 nm. A home-made deposition chamber was put inside and connected with the regular machine chamber through a microfabricated orifice with feature size smaller than 1 mm. According to the free molecular flow theory, the pressure inside the deposition chamber can be predictably and controllably reduced, thereby an ultra-low output of Parylene deposition, as low as 0.08 nm/g, was successfully obtained. The deposition precision was increased by 4 orders of magnitude compared to that of a direct Parylene deposition. This highly controllable and reliable ultra-thin Parylene deposition technique will find promising applications in flexible electronics and biomedical microdevices

Gorham’s disease: treatment with an autologous iliac bone graft and a reverse total shoulder arthroplasty

Abstract Background Gorham’s disease (GSD) is a rare osteolytic disease with unclear etiology, and no known prevention or effective treatment. Here we report a new surgical treatment for a case of GSD in September 2017. Case presentation We report GSD in a 52-year-old woman. She had disappearance of her humeral head and a defect of the glenoid bone in her left shoulder joint, which were serious obstacles to joint function. We used an autologous iliac bone graft to repair the glenoid bone defect and a reverse total shoulder arthroplasty. After surgery, humeral osteolysis did not continue, and her shoulder function recovered well. Conclusions This case suggests that autologous bone grafting can still be used to treat GSD despite it being an osteolytic disease. The successful treatment suggests that this method could be used for GSD in other bones
