Objective To explore the effect of PDCA circulation on the effective utilization of the disposable articles in the operating room.Methods 9,362 aseptic articles for 446 operations in the departments of general surgery and hepatobiliary surgery during January to May 2012 were put in the pre-experiment group,in which PDCA circulation was not used.Another 11,973 articles for 501 operations in the same departments during June to November 2012 were set as the post-experiment group,in which PDCA circulation was used.The two groups were compared in terms of the effective utilization rate and the degree of doctor’s satisfaction with the nurses in the operation room.Result After the implementation of PDCA circulation,the effective utilization rate and the degree of doctor’s satisfaction were both significantly higher than before the implementation(both P<0.05).Conclusion PDCA circulation for the management of sterile disposable articles in the operation room may effectively improve the utilization rate of disposable articles, reduce wasting of articles and safe resources.

This article was aimed to study the therapeutic effects and anti-inflammatory effects of Chinese and west-ern medicine ointment on fungal infection animals. Guinea pig models which were infected with Trichophyton rubrum or Microsporum lanosum were applied to observe the effects of antifungal infections on She-Zhi Qin-Xian (SZQX) ointment by transdermal administration. The ointment is the combination of miconazole nitrate, snake oil and Sophora flavescens which is traditional Chinese medicine (TCM). Simultaneously, the models of croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling were established to observe the curative effect of SZQX ointment. The results showed that the SZQX ointment had a protective role on both guinea pig models. The microscopic scale of localized lesions in infected guinea pigs was significantly decreased (P< 0.01). The effect of SZQX ointment was better than the single using of Chinese or western medicine. The SZQX ointment was also able to significantly reduce the croton oil-induced mouse ear swelling and carrageenan-induced rat paw swelling (P< 0.05, or P< 0.01) with distinct anti-inflammatory effect. And the effect of SZQX ointment was superior to the single using of either Chinese or western medicine. It was concluded that the SZQX ointment had significant antifungal infection and anti-inflam-matory effect.

OBJECTIVE:To investigate toxic reaction of Compound zedoary turmeric oil cream in experimental rats with long-term consecutive transdermal administration,and to provide reference for safe use of it in the clinic. METHODS:60 SD rats were randomly divided into blank control (cream matrix) group,Compound zedoary turmeric oil cream intact skin and damaged skin low-dose and high-dose(5%,10%)groups,with 12 rats in each group,half male and half female. All of them were given relevant medicine twice a day. 92 d consecutive medication later,general situation of rats were observed,and body weight,blood routine(WBC,RBC,HGB,LYMPH,etc.)and blood biochemical indicators(AST,ALT,PA,etc.)were all detected;systemati-cal observation of organs,organ coefficient calculation and histopathology examination were carried out. RESULTS:There was no statistical significance in those indicators between Compound zedoary turmeric oil cream groups and blank control group (P>0.05),except hemoglobin decreased in intact skin low-dose group,while hemoglobin decreased,LYMPH and PA increased in dam-aged skin high-dose group(P<0.05). Pathology results showed that Compound zedoary turmeric oil cream had no significant toxici-ty for the main organs. CONCLUSIONS:Compound zedoary turmeric oil cream has no long-term toxicity to experimental rats.

The pathogenesis of diabetic retinopathy (DR) is complex.Antisense non-coding RNA (ANRIL) in the INK4 locus in long-chain non-coding RNA (lncRNA) is closely related to cell proliferation,differentiation,and individual development.It plays an important role in the dysplasia of retinal vascular endothelial cells and is a new field in the study of the pathogenesis of DR.According to the researches at present,ANRIL may plays its role in the occurrence and development of DR through the signal pathway of nuclear factor-κB and ROS/polyadenylation diphosphate ribose polymerase,and interact with p300,miR-200b,and EZH2 to regulating the expression and function of VEGF.Specific blocking ANRIL and its related pathwaysmay become a new target in the treatment of DR.

Objective To explore the clinical features and radiological findings of patients with Sturge-Weber syndrome (SWS).Methods A retrospective study was performed on the course of illness,clinical data and neuroimages of 8 patients with SWS,admitted to our hospital from June 2012 to November 2015.Results The main symptoms included facial hemangioma in 7 patients,epilepsy in 5 patients,headache in 4 patients,limb hemiplegia in 3 patients,glaucoma in 3 patients,and thyroid dysfunction in one patient.Neurological imaging showed subcortical calcification,brain atrophy,gyriform enhancement and increased pial vascular tortuosity.Fundus examination revealed optic atrophy and vascular malformations of choroid.All symptoms in the patients were alleviated after treatment.Conclusions SWS should be highly suspected in young patients who present with typical glaucoma,epilepsy or hemiplegia with/without facial hemangioma.CT angiography or MR imaging (especially susceptibility-weighted imaging) is required to confirm the diagnosis.If medications fail to control seizures,surgery could be considered in some patients.

4K laparoscopy brings opportunities and challenges to the development of rectal surgery. 4K laparoscopy can truly provide the structure of abdominal and pelvic fascia, so that surgeons can see more subtle anatomical structure. The clear and real picture under 4K laparoscopic system can reduce visual fatigue of surgeons, which make the operation easier and safer. Radical resection of right colon cancer includes complete mesocolic excision and D 3 lymphadenectomy. Through 4K laparoscopic system, surgeons can easily observe the fascia structure of right mesocolon and its mesenteric bed, distinguish the vascular anatomical relationship at the mesenteric root, which make D 3 lymphadenectomy safer with dissection of lymph nodes completely. The authors comprehensively analyze the related research progress at home and abroad, and systematically elaborate the region of dissection and significance of 4K laparoscopic right hemicolectomy for right colon cancer.

Laparoscopic radical surgery for rectal can-cer involves total mesorectal excision (TME), D 3 lymphadenectomy, and pelvic autonomic nerve preservation, the goal of which is trying to achieve completely radical cure for cancer and urogenital function preservation. In the actual operation procedure, the understanding of fascial anatomy in abdominal and pelvic cavity will help us to improve the quality of TME surgery for rectal cancer and to preserve the pelvic autonomic nerves. When entering the pelvic cavity, the identification of fascia propria of mesorectum, visceral fascia, pre-hypogastric nerve fascia, presacral fascia, ligament structures around the rectum and the Denonvilliers′ fascia in front of the rectum will help us to protect the pelvic autonomic nerves and avoid surgical injury. So the authors focus on how to identify the pelvic fascia structure clearly in laparoscopic radical resection for rectal cancer, furthermore, to master the concepts of fascia anatomy to realize TME for rectal cancer and to achieve pelvic autonomic nerve preservation.

Objective To study the expression difference and the meaning of interleukin (IL)-1β and Claudin-5 in the kidney and kidney's membrane between lupus mice and the control mice. Methods Gene expression difference of IL-1βand claudin-5 between lupus mice and control mice in their kidney and kidney's membrane was detected with quantitative polymerase chain reaction (Q-PCR). The location of the expression was identified by immunohistochemistry. One-way analysis of variance (ANOVA) was used to compare the means of each group, pair-wise comparison was used to compare the difference between multiple sample means. LSD method was used when the variance was equal, and Tamhane's T2 method was used when the variance was different. Results Q-PCR test results showed that IL-1β expression in lupus mice's kidney membrane (0.0095±0.0052) was statistically higher than lupus mice's kidney parenchyma (0.0057±0.0013) (t=2.137, P=0.0458) and control mice's kidney membrane (0.0045±0.0033) (t=2.709, P=0.0131), however, there's no statistical significant difference between control mice's kidney membrane and parenchyma (0.0065± 0.0011) (P>0.05), and there's no statistical difference between control and lupus mice's kidney parenchyma (P>0.05). Claudin-5 expression was statistically higher in control mice kidney membrane (0.0192 ±0.0048) than its kidney parenchyma (0.01156 ±0.002190) (t=4.009, P=0.0015) but statistically lower in lupus mice kidney membrane (0.0069±0.0004) than its kidney parenchyma (0.0098±0.0027) (t=2.727, P=0.0173);there's no statistical significant difference between control mice's kidney parenchyma and lupus mice's kidney parenchyma (P>0.05), and lupus mice's kidney membrane expression was statistically lower than control mice's kidney membrane (t=6.018, P=0.0001). Immun-ohistochemistry showed that IL-1β expression was mainly around glomerulus and membrane, but not renal tu-bule. Claudin-5 expression was mainly around glomerulus and membrane. Conclusion Immune inflammation induced by IL-1β has mainly shown in blood vessels, while claudin-5 has protective effect on lupus immune inflammation.

Single-port and reduced-port laparoscopic radical gastrectomy as the innovative surgery for gastric cancer are gradually accepted nowadays,and more attentions are also paid to single-port and reduced-port laparoscopic radical gastrectomy due to its better cosmetic effect,less pain,lower incidence rate of surgical site infection and more advantages in enhanced recovery after surgery.However,in the early stage,the development of single-port and reduced-port laparoscopic radical gastrectomy were facing challenges and obstacles on account of limited surgical skills,the lack of special laparoscopic instruments,laparoscope and multi-port Trocar.In recent years,the dilemma and difficult situations were gradually resolved following by surgical techniques innovation,laparoscopic instruments and facilities improvement.It is believed that single-port and reduced-port laparoscopic radical gastrectomy will have a good prospect and breakthrough in the field of gastric cancer treatment in the future.
