Methods We retrospectively analysed clinico pathologic data, the ways of operation and living time of 11 patients with bile duct carcinomas in choledochal cysts in two hospitals from 1986 to 1997. Results There were complete excision of the choledochal cysts associated with choledochojejunostomy in 4 patients, exploration of bile duct and drainage with T shape tube in 3 patients. And there were also the excision of the wall of bile duct cysts and the tumor and cholangioplasty, choledochocystoduodenostomy, biopsy, pancreaticoduodenectomy and cholangiojejunostomy at the porta hepatis, resection of original rhynchostoma of choledochojejunostomy in one patient, respectively. One patient has lived for 3.6 years after radical resection. Others lived for 13.6 months after operation. Conclusions It is the key of improving and lengthening lives to find this disease in the early stage and to resect radically as early as possible.

Abstract: This retrospective analysis examines the diagnosis and treatment of a case of chronic liver disease infected with Vibrio vulnificus, admitted to the First Affiliated Hospital of Hainan Medical University on August 8, 2023. The patient, a 34-year-old male fisherman, had chronic viral hepatitis B. He sustained a leg abrasion while fishing on August 3, and developed fever and continuous swelling pain in both lower limbs, more severe in the left limb, on the night of the injury. On the fourth day of the disease, he went to the local hospital where he received antibiotic treatment and was transferred to the First Affiliated Hospital of Hainan Medical College on August 8. Upon admission, the patient exhibited low blood pressure, high lower limb skin temperature, poor peripheral blood transport, visible scab, and signs of infectious shock. Within 12 hours of admission, an abscess incision and drainage procedure was performed on his left calf, along with negative pressure wound therapy, and tissue samples from the infected left lower limb were sent for microbial culture.The pathogen culture indicated a Vibrio vulnificus infection, and the histopathology results confirmed necrotizing fasciitis. Treatment included meropenem combined with vancomycin for infection control, maintenance of blood pressure and electrolyte balance, tenofovir disoproxil fumarate for antiviral therapy, and polyene phosphatidylcholine capsules for liver protection based on the drug sensitivity results. Additionally, levofloxacin and cefotaxime were administered for infection control and debridement was performed based on wound conditions. After 17 days of hospitalization, the infection was substantially controlled, but the liver function enzyme was still higher than the normal level, and the wound still had blood and exudation. The patient and his family members requested discharge; however, due to poor wound healing, he was readmitted on September 11, 2023, receiving antiviral and liver preservation treatment. On the fifth day,the secretion culture identified a co-infection with Corynebacterium striatum and Providencia stuartii infection. Corynebacterium striatum was subsequently reported as multidrug-resistant, prompting an immediate switch to sensitive antibiotics and supportive care. Sixteen days after readmission, the patient's general condition improved, but the liver function enzyme levels were still higher than normal, so he was discharged. Four months after discharge, a follow-up phone call revealed that the patient had actively pursued antiviral treatment and abstained from alcohol, showing reasonable wound recovery. The patient's case, with a typical exposure history and clinical manifestations, matches the characteristics of septic shock and necrotizing fasciitis caused by V. vulnificus. Clinically, it is crucial todiagnose and treat V. vulnificus infection early according to its pathological characteristics and clinical characteristics to improve the prognosis of patients.

Objective To explore independent risk factors of ventilator associated pneumonia (VAP) on severe craniocerebral injury patients, and propose nursing intervention measures to reduce occurrence of VAP. Methods A retrospective analysis was conducted on 73 severe craniocerebral injury patients with VAP postoperatively from January 2013 to June 2015, and 80 severe craniocerebral injury patients underwent mechanical ventilation without VAP postoperatively at the same time were selected as the control group. Through literature review, questionnaire was designed to collect potential impact factors of VAP in both two groups, the single factor analysis and Logistic regression analysis were applied to explore the VAP independent risk factors, and nursing intervention countermeasures were proposed to improve VAP clinical prevention. Results VAP incidence rate of severe craniocerebral injury patients postoperatively was 23.0%(73/317) , from which 81 strains were detected, the first three strains of strain spectrum were Klebsiella pneumonia (21.0% ), Bauman Acinetobacter (17.3% ) and pseudomonas aeruginosa bacteria (14.8% ). Single factor analysis showed there were significant differences on composition of two groups in age, preoperative Glasgow Coma Scale (GCS) score, operation times, artificial airway type, postoperative mechanical ventilation time, daily airway humidification frequency, daily sputum suction frequency compound injury, daily oral care times (χ2=1.809-11.936, P < 0.01 or 0.05). Logistic regression models showed duration of mechanical ventilation (OR≥7d=3.013; OR≥14d=3.695), secondary surgery (OR =3.111) , preoperative GCS score (OR =2.989), daily airway humidification frequence (OR =2.280), age (OR=2.237) had remarkable influence on occurrence of postoperative VAP (P<0.01 or 0.05). Conclusions The incidence rate of VAP in severe craniocerebral injury patients is higher, age, mechanical ventilation duration, preoperative GCS score, airway humidification degree, second surgery are the independent risk factors of VAP.

Objective To evaluate the effect of Jian Pi Bu Shen prescription on inflammatory factors and iron metabolism in the brain of T2DM model mice.Methods A total number of 30 healthy 12-week-old male mice were used in the present study.The groups were randomly assigned to one of the following experimental groups:(1) control group:n=5,the mice were maintained on a normal diet for 4 weeks;(2) model group:n=25,the mice were maintained a high fat diet for 4 weeks.Then,the mice were deprived of food for 12 hours before a single intraperitoneal injection of streptozotocin (STZ,30 mg/kg).Then,the blood glucose levels were measured randomly 3 times within 24 hours after injection.The mice whose blood glucose was less than 16.7 mmol/l would receive another single intraperitoneal injection of STZ.Finally,we got a total number of 19 mice meeting the criteria of animal model we described above.The final 19 mice were randomized to 2 groups:diabetes group (n=10)and Jian Pi Bu Shen (JPBS) group(n=9).JPBS group received gavage administration of JPBS Prescription 7.4 g/kg/d(8weeks).Diabetes group and control group were maintained treated with saline for 8 weeks.Mice were decapitated 24 hours after the last drug treatment.The mice brain tissue slices were prepared for pathological observation.To examine the effects of JPBS prescription on neuroinflammation and iron metabolism in cerebrum and hippocampi,the relative mRNA levels of IL-6,IL-1β,DMT1,FPN1 and CP were tested by RT-PCR.Results mRNA levels of IL-6,IL-1β and DMT1 in the brains of diabetes group were higher while the levels of FPN1 and CP were lower than that of the control group (P＜0.01).Compared with diabetes group,in JPBS group,mRNA levels of IL-6,IL-1β and DMTl in cerebrum and hippocampi were decreased while the levels of FPN1 and CP were increased (P＜0.01).The brain tissue slices of diabetes group showed neuron loss and signs of neurodegeneration.But JPBS group attenuated neurodegenerative change.Conclusion JPBS prescription can protect neuron from apoptosis,suppress neuroinflammation and attenuate iron metabolism,which may be one of the mechanisms of traditional Chinese medicine in treating cognitive dysfunction.
