Objective:To verify and compare the correlation and diagnostic efficacy of international bowel ultrasound segmental activity score（IBUS-SAS），bowel ultrasound score（BUSS），simple ultrasound score for Crohn's disease（SUS-CD），and simple ultrasound score（Simple-US）with endoscopic disease activity in Crohn's disease（CD）patients. To provide external validation of the diagnostic efficacy of intestinal ultrasound（IUS）score and theoretical basis for clinical selection of optimal IUS score.Methods:A total of 160 patients with clinical diagnosis of CD combined with IUS and intestinal endoscopy were retrospectively analyzed in the Second Affiliated Hospital of Zhejiang University School of Medicine from January 2022 to August 2024. IUS parameters were measured and scored with IBUS-SAS，SUS-CD，BUSS and Simple-US scores. Endoscopic SES-CD was used to evaluate intestinal disease activity in patients without history of intestinal resection，and Rutgeerts score was used to evaluate intestinal disease activity in patients with history of intestinal resection. Endoscopic remission in patients with CD was defined as SES-CD < 3 or Rutgeerts score i0 and i1，mild endoscopic disease activity was defined as 7 > SES-CD≥3 or Rutgeerts score = 2，moderate endoscopic disease activity was defined as 15 > SES-CD≥7 or Rutgeerts score i3，severe endoscopic disease activity was defined as SES-CD≥15 or Rutgeerts i4. The correlation and diagnostic efficacy of IBUS-SAS，SUS-CD，BUSS and Simple-US scores with endoscopic disease activity in patients with CD were compared and analyzed.Results:IUS scores including IBUS-SAS，SUS-CD，BUSS and Simple-US were significantly correlated with endoscopic intestinal disease activity，SES-CD and Rutgeerts scores in CD patients（ r s = 0.706，0.492，0.502，0.526；0.825，0.581，0.584，0.603；0.541，0.434，0.437，0.467；all P＜0.05）. Among them，IBUS-SAS showed better correlation than the other three IUS scores. ROC curve showed that IBUS-SAS，SUS-CD，BUSS，and Simple-US had high predictive values for endoscopic disease activity and endoscopic disease moderate-severe activity in patients with CD（AUC = 0.886，0.748，0.730，0.756；all P＜0.05）. The diagnostic efficacy of IBUS-SAS on the presence of endoscopic disease activity in patients with CD was significantly higher than those of the other three IUS scores . Conclusions:IBUS-SAS，SUS-CD，BUSS and Simple-US are significantly correlated with the endoscopic results of on intestinal disease activity of CD，and have high predictive values for intestinal disease activity status，among which IBUS-SAS is superior to the other three IUS scores. It is recommended that IBUS-SAS be used first to evaluate intestinal disease activity in patients with CD.

ADP-ribosylation factor 6 (Arf6), a small G-protein of the Ras superfamily, plays pivotal roles in multiple cellular events, including exocytosis, endocytosis, actin remodeling, plasma membrane reorganization and vesicular transport. Arf6 regulates the progression of cancer through the activation of cell motility and invasion. Aberrant Arf6 activation is a potential therapeutic target. This review aims to understand the comprehensive function of Arf6 for future cancer therapy. The Arf6 GEFs, protein structure, and roles in cancer have been summarized. Comprehending the mechanism underlying Arf6-mediated cancer cell growth and survival is essential. The structural features of Arf6 and its efforts are discussed and may be contributed to the discovery of future novel protein-protein interaction inhibitors. In addition, Arf6 inhibitors and mechanism of action are listed in the table. This review further emphasizes the crucial roles in drug resistance and attempts to offer an outlook of Arf6 in cancer therapy.

Objcetive: To explore the treatment of long segment defect of tibia by using tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap. Methods: From February 2012 to August 2017, The People′s Hospital of Zun Yi City Bo Zhou District treated 16 patients who had long segment defect of tibia.There were 11 males and 5 females, age from 22 to 58 years old, the average age was 42 years old. Iliac flap grafting with tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle was used to treat the defect of long segment of tibia. There were 4 cases with simple tibial defect and 12 cases with skin defect. The longest tibial defect was 5-8 cm. Results: In this study, four patients used iliac flaps with deep circumflex iliac pedicle, the area of flaps ranged from 2.5 cm×5.0 cm to 5.0 cm×10.0 cm, while the area of iliac flaps ranged from 5.0 cm×2.5 cm to 8.0 cm×4.0 cm. Twelve patients used grafting with tensor fascia lata combined with iliac flap, the area of flaps ranged from 5.0 cm×12.0 cm to 12.0 cm×23.0 cm, while the area of iliac flaps ranged from 7.0 cm×2.0 cm to 8.0 cm×4.0 cm. All 16 cases of bone flap were survived, fracture healing, without surgical complications. The average follow-up period was 1.5 years, the flaps had good appearance in 10 cases and was slightly bloated in 6 cases; the ankle had normal motion in 14 cases and had poor dorsal extension in 2 cases. X-ray films showed that the bone flap repaired the bone defects and reached bone healing. Conclusions Vascularized tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap grafts increase local blood supply and accelerate the process of fracture healing.

OBJECTIVETo investigate the distribution patterns of mosquito and mosquito-borne viruses in Dehong prefecture, Yunnan province, China.

METHODSMosquito samples were collected using the mosquito traps from five counties of Dehong prefecture on July, 2007 and 2010. Mosquito were cell cultured for viral isolation, and positive isolates were identified using RT-PCR and sequence analysis.

RESULTSA total of 43 634 mosquito comprised of 29 species representing six genera were collected. Culex tritaeniorhynchus and Anopheles sinensis comprised 78.69% and 14.77% of the total. Six strains of viruses were isolated from the mosquito pools. RT-PCR and phylogenetic analysis revealed three strains from Cx. tritaeniorhynchus, identified as genotype I Japanese encephalitis virus (JEV). One strain was identified from Cx. tritaeniorhynchus, as Getah virus (GETV). Two strains isolated from Cx. tritaeniorhynchus and Anopheles vagus were identified as Culex pipiens pallens Densovirus (CppDNV).

CONCLUSIONCx. tritaeniorhynchus had been the major species of mosquito and mainly transmitting vector of mosquito-borne viruses in Dehong prefecture. Genotype I JEV, GETV and CppDNV were the vectors causing transmission of mosquito-borne diseases in this area. Data from phylogenetic analysis showed that these newly discovered isolates seemed to have had close relationship with those viruses previously circulating in Yunnan and other provinces of China.

Objective To detect circumsporozoite protein (CSP) in anopheline vectors from south Yunnan and to evaluate ELISA in the detection. \ Methods\ Salivary glands of the anopheline mosquitoes were taken for finding sporozoites by microscopy and part of the glands was used for detecting CSP by ELISA. An. minimus was experimentally infected by blood from vivax malaria patient (with Plasmodium vivax) and examined for sporozoites and CSP. Eight species of anopheline mosquitoes were caught in the field and examined. Monoclonal antibodies to P.falciparum (Pf2A10) and P.vivax (Pv210, Pv247) were used in ELISA for detecting CSP. \ Results\ Sporozoites were found in the salivary glands of 27 out of 36 An. minimus experimentally infected (75\^0%), 29 were ELISA CSP positives (80\^6%), and 26 of the 27 mosquitoes showed Pv210 CSP positive. Among \{1 010\} parous anopheline mosquitoes from the field, 7 were found sporozoite positive (0\^69%), 8 were ELISA CSP positive (0\^79%), and 6 of the 7 mosquitoes showed CSP positive. Of \{4 675\} wild mosquitoes in 8 anopheline species with different ages, 11 were found CSP positive (0\^24%) including An.minimus, An.sinensis and An.maculatus with a positive rate of 0\^20%, 0\^24% and 0\^39% respectively.Among the 11 mosquitoes, 9 were Pv210 positive and 2 were Pf2A10 positive. Conclusion CSP detection by ELISA is a useful method to monitor the malaria transmission capacity of anopheline vectors.
