Objective To design a smoke purifier for laparoscopic surgery, and to test its application in reducing the use of carbon dioxide gas and reducing the concentration of harmful substances in laparoscopic surgery exhaust gas. Methods From April to September 2017, a total of 136 cases of hysterectomy and bilateral salpingo oophorectomy and pelvic lymph node dissection were divided into control group and experimental group by random number table method, with 68 cases in each group. Independent negative pressure suction pipeline was applied in the control group for direct suction. In the experimental group, the surgery exhaust gas first passed laparoscopic surgical smoke purifier, the intake pipe of which was transformed from an aseptic transfusion device. Gas would emit a sound alert when passing the double-valve one-way valve. After passing KP100 grade, KN100 grade filter element and a certain amount of protective coal pellet activated carbon, the smoke would be managed by the independent negative pressure suction pipeline. The amount of carbon dioxide gas used in the two groups and the concentration of harmful substances in the smoke of the experimental group before and after the operation were recorded. Results The amount of carbon dioxide gas used in the control group was (656.95±70.11) L, which was higher than that in the experimental group (613.70±75.63) L, and the difference was statistically significant (P< 0.01). In the experimental group, PM10, PM2.5, PM1.0, formaldehyde and total volatile organic compounds (TVOC) before the application of purifier were (206.90±30.48) μg/m3, (195.74±27.23) μg/m3, (220.22±37.60) μg/m3, (0.52±0.02) mg/m3 and (4.35±1.79) mg/m3, which were all higher than those after the application of purifier (4.26±1.02) μg/m3, (6.54±2.05) μg/m3, (7.89±3.38) μg/m3, (0.34±0.01) mg/m3and (0.31±0.17) mg/m3respectively, and the differences were statistically significant (P<0.01). Conclusions The purifier can reduce the amount of carbon dioxide gas used in laparoscopic surgery, reduce the harmful substances in surgical exhaust gas and reduce the harm to the environment and medical staff.

Objective:To evaluate the clinical effect of high-intensity interval training and moderate continuous aerobic training on patients classified as low risk for exercise rehabilitation after a percutaneous coronary intervention (PCI).Methods:A total of 43 patients considered low-risk after a PCI were randomly divided into a high-intensity interval training group (HIIT group, 22 cases) and a moderate continuous aerobic training group (MCT group, 21 cases). The HIIT group received high-intensity, but aerobic interval training involving 8 rounds of 3 minutes of high-intensity exercise with 2-minute intervals at 80% of peak power over 40 minutes, 3 times a week. The MCT group trained continuously at 60% of peak power for the same duration. After 12 weeks both groups were given an ultrasound examination and a cardiopulmonary exercise test to assess their cardiac functioning and exercise endurance. The subjects′ life quality was evaluated and compared using some items from the SF-36 scale.Results:Before the training, no significant differences were observed in the average left ventricular ejection fraction, stroke volume, peak power, peak oxygen uptake, anaerobic threshold, physiological functioning, physical pain, general health or social functioning between the two groups. After the training significant improvement in all these indicators was observed in both groups, but compared with MCT group, the average left ventricular ejection fraction, stroke volume, peak power and peak oxygen uptake of the HIIT group were significantly better.Conclusions:High-intensity, aerobic interval training is superior to moderate but continuous aerobic training for improving the cardiac functioning and exercise endurance of patients suitable for exercise rehabilitation after a PCI. But there is no significant difference in their effect on the short-term quality of life.

Objective To find an effective and convenient restraint band for the upper limb of the non-compression side for the patients in the lateral decubitus operation in the Neurosurgery Department. Methods From August 2017 to March 2018, patients in the lateral decubitus operation in the Neurosurgery Department,who from the Second Hospital of Hebei Medical University, were selected as the research objects. The self-made posture restraint belt was made of professional exercise shoulder, forearm sheath, binding band and magic stick. By using random number table produced by SPSS 22.0 edition, 160 patients who underwent lateral decubitus operation in the Neurosurgery Department were randomly divided into the control group and the observation group, with 80 cases in each group. In the control group, the conventional shoulder straps and wrist restraint bands were used, while the self-made lateral decubitus upper limb restraint band was used in the observation group. The differences of the time of lateral decubitus placement, the incidence of pressure sore in the non-compression side of the upper limb and the efficiency of restraint were observed and compared between the two groups. Results The time of lateral decubitus placement (365.97±42.08) s and the incidence of pressure sore in the non-compression side upper limb (10.0%) were higher than those of the observation group[ (302.69± 38.25)s, 1.3%]. The differences were statistically significant (P＜0.05). The efficiency (100.0%) of the non-compression side upper limb restraint in the observation group was higher than that in the control group (91.3%). The difference was statistically significant (P＜0.05). Conclusions The self-made upper limb restraint band for neurosurgery lateral position can effectively expose the surgical field, improve the comfort degree of patients, and improve the efficiency of posture placement and restraint.

Objective:To explore the clinical effect on reconstruction of the soft tissue defects after resection of mucous cysts of distal interphalangeal joint (DIP) with transfer of the flap of dorsal branch of proper palmar digital artery.Methods:From September 2021 to September 2023, 8 patients (8 digits) with mucous cysts on DIP were treated in the Department of Hand and Microsurgery, the Affiliated Hospital of Binzhou Medical University. All 8 cases were females, aged 55-65 years old, with an average age of 60 years old. The cyst was located in the thumb in 1 case, in the index finger in 3 cases, in the middle finger in 3 cases, and in the ring finger in 1 case. After extensive resection of the mucous cysts, the size of soft tissue defects was at 0.8 cm×0.6 cm-1.7 cm×0.9 cm. Pedicled with the dorsal branch of proper palmar digital artery, the flaps adjacent to the defects were designed to cover the wounds. The size of the flaps was 1.2 cm×1.0 cm-2.0 cm×1.2 cm. Donor sites of the flap were covered by the full thickness skin grafts of medial upper arm. The postoperative follow-up was conducted by the combination of outpatient revisits and telephone reviews to observe the survival of the flap, and the functional recovery was evaluated according to the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association.Results:All flaps survived well after surgery. Postoperative follow-up ranged from 4 to 12 months, with a mean of 10 months. At the final follow-up, there was no recurrence of mucous cyst and all symptoms disappeared. All flaps healed well, with good appearance, soft texture and without obvious difference in colour from the surrounding skin. All skin grafts healed in one stage. The range of motion of the affected DIP was 0°-70°, and the TPD was at 7-8 mm, both caused no impact on daily life. The outcomes were excellent according to the evaluation criteria set by the Evaluation Standard of Upper Limb Functional of Hand Surgery of Chinese Medical Association.Conclusion:The flap pedicled with dorsal branch of proper palmar digital artery has obvious advantages with less damage and simple operation in the treatment of a mucous cyst of DIP. It is an ideal surgical procedure.
