Gastric cancer is one of the common tumors in the world and a major cause of cancer death.Although the 5-year survival rate of gastric cancer patients has increased greatly with the improvement levels of diagnosis and treatment,the high malnutri-tion rate of gastric cancer patients still has a significant impact on their overall survival and quality of life.Malnutrition is considered an independent prognostic factor for cancer patients,early detection of malnutrition in gastric cancer patients and more reasonable peri-operative nutritional support play an important role in the survival and prognosis of gastric cancer patients.This article combines exist-ing research at domestic and abroad to review the nutritional risk screening and assessment of gastric cancer patients during periopera-tive period,as well as the research progress of perioperative nutritional support and immunonutrition,in order to provide more compre-hensive nutritional management strategies for patients with gastric cancer during the perioperative period.

Objective:To explore the clinical efficacy of Masquelet technique combined with tissue flap transfer in the treatment of infectious composite bone and soft tissue defects in the early and middle stages after internal fixation for tibial fractures.Methods:From October 2017 to November 2020, 12 patients (13 tibial fractures) with infectious bone and soft tissue defects in the early and middle stages after internal fixation were treated in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of CPLA by two-phased surgery with retaining internal fixation. Phase I procedures were thoroughly removal of the infected lesions and failed screws, preserving internal implants as many as possible, implantation of absorbable calcium sulphate and an antibiotics blended string of beads into the distal and proximal medullary cavity of the fractured bones, filling the bone defect and wrapping the internal implants with antibiotics loaded bone cement. The size of defects was 3.5 cm × 5.0 cm-7.5 cm × 14.5 cm, and the flaps for wound coverage sized 4.0 cm × 5.5 cm-8.0 cm × 15.0 cm. As for the repair of donor site, 8 limbs were sutured directly, 5 limbs could not be closed completely, and the remaining wounds were covered by skin grafting after suture. Based on well control of infection and stable clinical signs, fillings of bone cement were then removed in Phase II surgery, or 6-9 weeks after primary surgery. Autologous cancellous bone pieces or composite allogeneic bone were fully implanted around the induction membrane formed by Masquelet technique, and auxiliary steel plates were implanted for internal fixation of unstable fractures. After discharge, the patients visited the outpatient clinic regularly, and combined with Wechat follow-up. The texture, colour and bone healing were observed. At the last follow-up, the function of the affected limbs were assessed according to Johner-Wruhs evaluation standard.Results:After Phase I surgery, 13 flaps survived smoothly without vascular compromise. The wounds healed in Phase I. Two patients (2 sides) had recurrent infections. Re-debridement was performed and external fixation was applied after removal of internal fixation. After Phase II surgery, all patients were included in 12-26 months of follow-up, with an average of 18 months. Thirteen lower leg fractures healed well, and the time of bone healing was 16-25 (average 19.5) weeks. The Johner Wruhs criteria was used in evaluation of the function of affected limbs, and it was found that 6 patients were in excellent, 5 in good and 2 in fair.Conclusion:It is feasible while preserving the internal implants, to use membrane induction technique (Masquelet technique) combined with flap transfer, together with the absorbable calcium sulphate antibiotic sustained-release beads as a carrier in the phased treatment of infectious bone defects and bone exposure in the early and middle stages after the surgery of tibial internal fixation. It also gives a higher rate of excellence in surgical outcome. This study explores a treatment procedure for traumatic bone infection combined with composite soft tissue defects.

OBJECTIVE To analyze the medication reconciliation for the inpatients in cardiovascular medicine department ，to provide reference for the establishment of working mode of clinical pharmacists in the department of cardiovascular medicine and to provide a basis for clinical pharmacists and community pharmacists developing pharmaceutical care for patients after transfering to community health center. METHODS From October 2020 to September 2021，newly admitted or newly transferred inpatients with chronic disease were selected from Shiyan People ’s Hospital of Shenzhen Bao ’an District. Medication reconciliation was conducted by clinical pharmacists after pharmaceutical consultation. According to the Pharmaceutical Care Network Europe （PCNE） classification system V 9.1，the existing drug-related problems （DRPs）were classified and summarized. The effectiveness and safety evaluation，medication education and other measures were provided ，and the acceptance of intervention was analyzed at the same time. RESULTS A total of 100 patients were included ，including 54 males and 46 females. The average age was （60.21±9.69） years，the average number of chronic diseases was （2.84±0.83），and the median number of drugs was 5.00. Among them ，110 treatment drug deviations were found in 74 patients，involving 10 categories and 61 drugs. Top three drugs in the list of accumulative drug deviation were cardiovascular system drugs （35 deviations），digestive medicine drugs （16 deviations）and endocrine system drugs （15 deviations）. The above treatment drug deviation may cause 122 DRPs， mainly “treatment effectiveness”problems（74 DRPs），and the causes were “inappropriate medication time ormedication interval ”（32 DRPs）， followed by “inappropriate drug combination ”（10 DRPs）. Interventions to DRPs mainly concentrated on patient level ，drug level （58）and doctor level （58），155 of which （84.70％）were fully accepted and implemented. CONCLUSIONS Some patients have a weak awareness of medications according to doctor ’s advice；drug reconciliation led by clinical pharma- cists at admission can fully understand the potential drug problems of patients ，and help doctors improve the drug compliance of patients and ensure their medication safety .

Objective:To correlate climate change with epistaxis in Yueqing of Zhejiang province and to provide evidence for the diagnosis and treatment of epistaxis.Methods:A total of 1 800 patients with epistaxis, who received treatment in Yueqing People's Hospital between October 2018 and October 2019, were included in this study. The data of these patients were input into the Microsoft Excel software. They were summarized and sorted as per admission time. Climate change was correlated with epistaxis.Results:Daily average temperatures were negatively correlated with epistaxis ( r = -0.65, P = 0.003). A non-linear, inverted-U-shaped relationship was observed between daily relative humidity and epistaxis. When the daily relative humidity was < 65%, daily relative humidity was positively correlated with epistaxis ( r = -0.54, P = 0.007).When the daily relative humidity was > 65%, daily relative humidity was negatively correlated with epistaxis ( r = -0.68, P = 0.002). There was a nearly linear positive correlation between diurnal temperature range and epistaxis ( r = 0.52, P = 0.009). There was a linear and positive correlation between daily average atmospheric pressure and epistaxis ( r = 0.60, P = 0.004). The risk of epistaxis increased by 1.48% (95% CI: -2.15 to -0.81) when the temperature decreased by 1 ℃. When daily relative humidity was < 65%, the effects of humidity change on the risk of epistaxis were not statistically significant ( P > 0.05). When the relative humidity of the day was > 65%, the risk of epistaxis decreased by 1.82% (95% CI: -2.71 to -0.93) for every unit of humidity rise. The risk of epistaxis increased by 2.86% (95% CI: 0.54 - 5.18) for every 1 ℃ increase in temperature. The risk of epistaxis increased by 1.18% (95% CI: 0.50 - 1.87) for every 1 Pa increase in air pressure. Conclusion:Temperature change is negatively correlated with epistaxis. Atmospheric pressure and diurnal temperature range are positively correlated with epistaxis. Temperature change, atmospheric pressure, and diurnal temperature have temporary effects on epistaxis. High humidity has an obvious long-term protective effect against epistaxis.

Objective:To explore a surgical technique and treatment outcomes of the segmentle bridging reconstruction for severed fingers with single segmentle defect by using the free second toe bone-joint composite tissue combined with the great toe flap.Methods:From June 2010 to September 2017, 5 patients suffered from severed segmental defect of finger were treated. According to the defects of bone-joints, blood vessels, nerves, tendons and other soft tissues, the reconstruction surgery was designed to create a Flow-through bridging composite flap pedicled with the first dorsal metatarsal artery or the plantar artery. The blood vessles carried by the pedicle were anastomosed with the vessels in the finger to restore the blood supply to the distal finger while having the defected finger segment reconstructed. A Flow-through bridging composite flap was created by taking the second toe bone-joint composite tissue combined with a C-shaped or half-moon shaped flap from the fibular side of the great toe. Skin graft, retrograde lateral tarsal flap or free perforator flaps were used in 3 cases to repair the donor sites of the great and second toes. Iliac strip was implanted in 2 cases for toe salvage. Kirschner wires were removed 4-6 weeks after surgery followed by functional exercise.Results:All of the 5 reconstructed distal segments of the fingers survived with the healing of fractures in 8-12 week after surgery. The postoperative follow-up lasted 6-36 months and all the patients had the follow-ups at the outpatient clinic. It was found that the maximum flexion of the reconstructed interphalangel joint was 60 degrees together with dorsiflezion. According to the evaluation standard of the reconstructed function for thumb and finger issued by the Hand Surgery Society of the Chinese Medical Association, 3 fingers were in excellent and 2 in good. No obviouse affect on walking was found in all the patients.Conclusion:The free second toe joint composite tissue together with the great toe flap can be used to bridge the single segmental defect of a finger. It restores the blood supply to as well as the appearance of the distal finger, helps the recovery of the reconstructed distal finger. It is an ideal technique in the treatment of a severed distal segment of the finger.

Objective:To investigate the efficacy of the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery to repair the composite tissue defect in the Achilles tendon area.Methods:From January 2016 to June 2021, 12 patients suffering from infectious wound with defect of Achilles tendon were treated in the Department of Trauma and Microscopic Orthopaedics, 988th Hospital of the Joint Logistics Support Force of PLA. The area of soft tissue defect around Achilles tendon was 2.5 cm× 4.5 cm-8.0 cm×12.5 cm, and the length of the defect of Achilles tendon was 3.0-7.0 cm. The defect around the Achilles tendon were repaired with the nutrient vessel of medial and lateral sural subcutaneous nerve chimeric Achilles tendon flap (ATF) and the posterior perforating branch of peroneal artery was used as the vessel of blood supply. The size of flap was 3.0 cm×5.0 cm-9.0 cm×13.0 cm, and the size of the ATF was 3.0 cm×4.0 cm-3.0 cm×8.0 cm. The donor sites were sutured directly (8 cases) or repaired with skin graft (4 cases). External fixation were put on for 6 weeks after surgery. Then the external fixation was removed and the functional exercise gradually started. Outpatient clinic follow-ups were carried out regularly. Thermann Achilles tendon function assessment system was used to evaluate the last follow-up.Results:The chimeric ATF was harvested and the blood supply of each flap was good during the operation. There was no vascular crisis after surgery. The flaps survived smoothly and the wound achieved grade A healing. All patients were entered follow-up that lasted for 10-24 months. There was good appearance of flaps with minor bloating, and the colour of flaps was similar to the skin around the receiving site. The texture was soft with normal function of the lower legs and ankle. Tendon function was evaluated by Thermann Achilles tendon function assessment system, the result were 8 cases in excellent and 4 cases in good.Conclusion:The nutrient vessel of medial and lateral sural subcutaneous nerve chimeric tissue flap based on posterior perforating branch of peroneal artery can accurately repair a composite tissue defect in the Achilles tendon area, and it is one of the effective methods for the repair of a composite soft tissue wound with Achilles tendon defect.
