The distribution of collagen Ⅳ (CⅣ) and its correlation with renal histological lesions were investigated in 107 cases with IgA nephropathy. Strong positive staining of CⅣ and Fn was found in glumerruli with crescents, segmental and global sclerosis, as well as in the tubular basement membrane and interstitium. The extent of CⅣ deposit was correlated well with tubular atrophy, interstitium fibrosis, infiltration of cells and renal pathologic changes. The results show that the increment of CⅣ and Fn in glomeruli is associated with the development of crescents, glomerular sclerosis. The inflammation of interstitium may stimulate renal tubular cells to produce extravagent amounts of CⅣ, which might further result in tubular atrophy and fibrosis.

Objective To investigate nursing interns’knowledge and attitude towards needle stick injury before clinical practice.Methods In 20-23 June,2015,nursing interns who were about to start clinical practice in a hospi-tal were investigated,nursing interns’knowledge and attitude towards needle stick injury were surveyed through questionnaire.Results A total of 350 questionnaires were distributed,324 (92.57%)responded questionnaires were available.40(12.35%)questionnaires were responded by male interns,and 284(87.65%)were by female in-terns;34(10.49%)interns had bachelor degree;the mean age of interns were (20.83 + 1 .24)years old.The correct answer rates about questions related to injury occurring during needle recapping and wearing gloves were low (about 60%).About 70% of the interns gave the correct answers to questions about hepatitis B infection due to needle stick injury following hepatitis B vaccination,as well as medication after injury.Score for individual question about attitude towards needle stick injury was ≤3,the major related problems were susceptibility of blood borne diseases and recapping needles.Conclusion Needle stick injury-related knowledge and attitude among nursing interns is inadequate,including recapping needles,timely report,susceptible to infectious diseases,and so on.It is necessary for schools and teaching hospitals to strengthen the education about occupational protection among nursing interns, so as to improve the attitude and ability of professional protection.

Objective To explore the clinical efficacy of enteral nutrition combined with traditional Chinese medicine (TCM) acupuncture and moxibustion for treatment of craniocerebral trauma complicated by gastric paralysis.Methods A prospective study was conducted.One hundred and sixty-seven patients with craniocerebral trauma complicated by gastric paralysis admitted to the Department of Neurological Critical Care Medicine in Affiliated Hospital of the Logistics University Chinese People's Armed Police Force from January 2013 to October 2015 were divided into single group (83 cases) and combined group (84 cases) according to the random number table method.The basic treatment program was the same in the two groups.On the basis of gastrointestinal decompression,a nasojejunal tube was indwelled in the digestive canal of the patients in single group,and the nutrient food could be given by dripping slowly and continuously through the tube into the body,while in the combined group,they were additionally treated by acupuncture and moxibustion at auricular point,zusanli and neiguan acupoints,1 time a day,each time 30 minutes.Both groups were treated consecutively for 30 days,and then the clinical efficacies were evaluated.Before and after treatment in both groups,the changes of total serum protein (TP),pre-albumin (PA),hemoglobin (Hb) were observed;the incidences of reflux,vomiting,abdominal distension,diarrhea,pulmonary infection and intestine derived infection were also evaluated.Results After treatment the levels of TP,PA,Hb were significantly higher in combined group than those in the single group [TP (g/L):36.97 ± 2.17 vs.33.14± 2.13,PA (mg/L):215.19 ± 7.91 vs.203.15 ± 6.12,Hb (g/L):126.73 ± 11.17 vs.117.61 ± 11.24,all P ＜ 0.01].The numbers of patients with reflux,vomiting,abdominal distension,diarrhea were significantly lower in combined group than those in the single group,respectively (the number of patients had reflux being 15 cases vs.31 cases,vomiting 13 cases vs.28 cases,abdominal distension 17 cases vs.29 cases,diarrhea 17 cases vs.31 cases) and pulmonary infection (17 cases vs.29 cases),intestine derived infection (4 cases vs.12 cases),all the above comparisons showing statistically (all P ＜0.05).Conclusions Enteral nutrition combined with acupuncture and moxibustion treatment can effectively enhance the patients' nutritional status,reduce gastrointestinal dysfunction and the incidence of complications,thus the prognosis of patients with craniocerebral trauma complicated by gastric paralysis is obviously improved.

Nurses play a key role in disaster prevention, delivery and management of care in disaster situations. Training high education level and enhancing disaster core competencies of disaster nurses are essential part in response to mass casualty incidents and reserving the nursing talent. Masters′degree of disaster nurses began in 2013 in China. At that time, disaster nursing task force was composed of faculty members from both the Hong Kong Polytechnic University and School of Nursing in Sichuan University, and then, students of disaster nursing were enrolled by School of Nursing in Shandong University and Chuanbei College. Masters′ degree training programme of disaster relief nurses was not perfect in China. This paper reviewed the studies on masters′degree training programme of disaster relief nurses.

Background:Celiac disease is an autoimmune enteropathy which can present with patchy mucosal lesions.Therefore,the diagnosis of the disease requires histological evaluation of multiple site biopsies.Aims:To analyze the pathological characteristics of multiple site small intestinal biopsies in adult patients with celiac disease and provide reference for early identification and diagnosis of celiac disease.Methods:The pathological data of 22 adult patients who were newly diagnosed as having celiac disease at the People's Hospital of Xinjiang Uygur Autonomous Region from August 2019 to April 2022 were collected retrospectively.All patients were positive for serum anti-tissue transglutaminase antibody IgA,and biopsies of duodenal bulb,descending part of the duodenum and terminal ileum were obtained under endoscopy.Histological examination was performed by experienced pathologists according to the modified Marsh grading system.Results:The most common pathological grade of duodenal bulb(50.0%)and descending part of the duodenum(45.5%)was Marsh Ⅲc,while those of terminal ileum was Marsh Ⅲa(63.6%).All of the bulb biopsies,95.5%of the descending part and 72.7%of the terminal ileum biopsies showed characteristic histological changes of celiac disease.Mucosal pathology was patchy in 7 patients,of which one patient was duodenal bulb and terminal ileum involved,and 6 were duodenum involved only.Fifteen patients had diffuse small intestinal mucosal pathology involving duodenal bulb,descending part and terminal ileum,of which 4 patients showed concordant histology(the same Marsh grade in duodenal bulb,descending part and terminal ileum)and 11 patients showed discordant histology.In 18 patients(81.8%),duodenum was the only affected site or duodenum showed more serious mucosal lesions compared with terminal ileum.Conclusions:Adult celiac disease may affect the whole small intestine,and the mucosal involvement may be patchy,which highlights the importance of taking small intestinal biopsies from multiple sites repeatedly in the diagnostic work-up of celiac disease.

Objective:To investigate the efficacy of induced membrane technique combined with anterolateral thigh flap transfer in treating composite foot defect.Methods:A retrospective case series study was performed for 7 patients with composite foot defect treated at 920th Hospital of Joint Logistic Support Force of PLA from February 2014 to December 2018. There were 5 males and 2 females, with the age of 20-73 years [(38.9±16.3)years]. The composite defect located at the forefoot in 5 patients, midfoot in 1, and hindfoot in 1. There were 9 metatarsal bone defects, 1 medial cuneiform bone defect, and 1 calcaneus bone defect. The size of soft tissue defect varied from 6 cm×5 cm to 70 cm×35 cm. At stage I, the anterolateral thigh flap transfer and vancomycin loaded cement implantation were performed. The flap survival and complications were recorded. At stage II, the cement was removed and autogenous bone was grafted into the induced membrane. The duration of two-stage operation, bone union time, and complications were recorded. The postoperative function was assessed using Maryland foot score system before operation and at the last follow-up and postoperative compications were documented.Results:All patients were followed up for 22-54 months [(33.8±9.7)months]. At stage I, flaps survived in all patients, and bulking of the flap was seen in 3 patients. One patient with calcaneus bone defect had repeated infection after operation, and received debridement. At stage II, 6 patients received bone grafting surgery. The duration of two-stage operation was 2-4 months [(2.8±0.9)months]. The bone union time was 3 and 7 months [(4.7±1.2)months]. At the last follow-up, the Maryland foot function score was 63-92 points [(82.1±8.7)points], significantly different from 0 point before operation ( P<0.01). The results were excellent in 1 patient, good in 5, and fair in 1. Except for one nonunion of metatarsal bone, all the other 8 sites were with bone union uneventfully. Conclusion:The induced membrane technique combined with anterolateral thigh flap transfer is an effective protocol for composite foot defect, which can well repair soft tissue and bone defect, and restore walking.

Objective:To investigate the preliminary clinical effect of posterior interosseous artery propeller flap in the repair of dorsal of wrist and hand wounds.Methods:From March, 2015 to December, 2019, 9 cases of dorsal of wrist and hand wounds were repaired with posterior interosseous artery propeller flap, including 6 cases of dorsal hand defect and 3 cases of dorsal wrist defect. Defect area: 6 cm × 4 cm-3 cm × 3 cm; There were 3 cases of metacarpal fracture, 1 case of phalangeal fracture and 1 case of tendon rupture. According to the size and shape of the wound, the posterior interosseous artery propeller flap was designed to transfer and repair the soft tissue defect wound. The size of the flap: 20 cm × 5 cm-12 cm × 3 cm, the size of posterior interosseous artery propeller flap was recorded and the surgical characteristics were summarized; The survival of the flap, donor and recipient complications were observed and followed-up.Results:All flaps were cut smoothly and the donor areas were sutured directly. The flap survived completely in 8 cases and partial necrosis in 1 case; One case complicated with wound infection. The follow-up ranged from 6 to 31 months, with an average of 14 months. The texture and shape of the flap were good; The last DASH score was 3-18, with an average of 9.3; There were 2 cases of mild scar hyperplasia in the donor area and 1 case of mild scar hyperplasia at the edge of the flap.Conclusion:Posterior interosseous artery propeller flap may be an effective method to repair small and medium-sized wounds of dorsal of wrist and hand.

Objective:To estimate the preliminary result of circumflex scapular perforator propeller flap in reconstruction of axillary scar contractures.Methods:From January 2016 to June 2021, circumflex scapular perforator propeller flaps were used in 7 cases for reconstruction of soft tissue defect after axillary scar contractures. Patients were 5 males and 2 females. Age ranged from 23 to 38 years old, mean age of 27.7 years old. According to Kurtzman and Stern classification of axillary scar contractures, there were 1 case with type 1a, 1 with type 1b, 2 with type 2, and 3 with type 3. The preoperative range of motion of the shoulder joint were 40°-85°, with an average of 63.7°. All the patients were underwent scar release and circumflex scapular perforator propeller flap transfer. All flaps were transferred as the manner of perforator propeller flap. All the donor sites were closed directly. The defects after releasing ranged from 5.0 cm×7.0 cm to 11.0 cm×9.0 cm, and the flaps ranged from 16.0 cm×7.0 cm to 24.0 cm×9.0 cm. Flap survival, complications of donor site and recipient site were recorded after surgery. The range of motion of the shoulder joint, donor and recipient sites were reviewed in outpatient clinic.Results:All flaps survived uneventfully after surgery, besides 1 case complicated with distal venous congestion. The follow-up time ranged from 6 to 23 months, with an average of 12 months. The texture and contour of the flaps were good in all. At last follow-up, the range of motion of the shoulder joints were 90°-120°, with an average of 107°. Mild scar hyperplasia occurred in 2 cases.Conclusion:The circumflex scapular perforator propeller flap is an effective protocol in reconstruction of axillary scar contractures.
