Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective:To discuss the occurrence, treatment and prevention of benign anastomotic stenosis after radical resection for rectal cancer.Methods:The clinical data of 63 patients with benign anastomotic stenosis from Jan. 2016 to Dec.2020 at Department of Gastrointestinal Surgery, Renji Hospital Shanghai Jiaotong University School of Medicine, were retrospectively analyzed, including general conditions, intraoperative conditions, postoperative complications, anastomotic stenosis, treatment process and outcome. The relationship between stenosis type and treatment and outcome were analyzed.The measurement data obeying normal distribution was expressed by ( Mean± SD), and the t test was used comparison between groups. The chi-square test was used comparison between enumeration data. Results:Of all the 63 patients, 22 (34.9%) cases presented with membranous stenosis, 30 (47.6%) cases with tubular stenosis, and 11 (17.5%) cases with diffused stenosis. Three of the 9 patients with high stenosis underwent balloon dilatation through endoscopy, 3 were placed with self-expandable metal stent and the rest 3 patients underwent resection and reconstruction of the anastomosis. All the 54 patients with low stenosis underwent digital anal expansion, and finally the effective rate was 53.7% (29/54). Endoscopic balloon dilatation was successfully performed in 8 cases, including 4 cases were placed metal stent throngh endoscopy. Eight patients underwent trans-anal stricturotomy. In 5 patients with low diffused stenosis, either ileostomy was preserved or permanent colostomy was performed due to failure to treatment. There were more male patients, protective ileostomy, anastomotic leakage and low stenosis in patients failed to treatment than in the cured patients ( P>0.05). However, all the 5 patients who failed to treatment were suffered from diffused stenosis, and the difference was statistically significant compared with those who were cured ( P<0.05). Conclusions:Postoperative anastomotic stricture after anterior rectectomy requires different treatment strategies according to the location and types of stricture. Endoscopic balloon dilatation is preferred for high stenosis, and metal stents can be placed optionally. Digital anal expansion is preferred for low anastomotic stenosis, and endoscopic or minimally invasive transanal surgery is feasible if digital anal expansion fails.

The development of information technology in the medical industry is accelerating the construction of 3-level rehabilitation networks centering on community-based rehabilitation, which is based on the Internet and in combination with the Internet of things(IOT). A municipal rehabilitation hospital cooperated with the health centers of sub-district communities in the city to build a remote rehabilitation network based on IOT technology, for rehabilitation training of community stroke patients. The two sides worked out a cooperation scheme on project management, designed and built a remote community rehabilitation management model. Under the remote monitoring and equipment data IOT, the medical team of the municipal rehabilitation hospital could formulate the therapeutic plan according to the immediately obtained relevant functional evaluation data, and the medical team of the community health service center was responsible for the implementation of the plan. Fifty-three patients in the experimental group received the training of remote lower limb intelligent feedback system based on IOT together with routine rehabilitation training. After 8 weeks of treatment, the functional evaluation data of the two groups were improved in varying degrees( P< 0.05), but the improvement of the experimental group was significantly better than that of the control group( P < 0.05). Remote rehabilitation under the construction path of remote rehabilitation network based on IOT technology could significantly promote the improvement of post-functional rehabilitation of community stroke patients. This study can provide reference for the construction of three-level remote rehabilitation networks based on IOT and the implementation of home-based remote rehabilitation therapy in the future.

【Objective】 To evaluate the efficacy of Nd: YAG laser therapy adjunct to subgingival scaling and root planning (SRP) for treating severe chronic periodontitis. 【Methods】 We selected patients with severe chronic periodontitis whose teeth were distributed in 4 quadrants of the mouth, with probing depth (PD) of 5-8 mm, attachment loss (AL)≥5 mm and bleeding on probing (BOP). These teeth were randomly divided into three groups: SRP group, SRP+L group (Nd: YAG laser after SRP treatment), and L+SRP group (SRP after Nd: YAG laser treatment). We recorded parameters including BOP, PD and AL of the three groups at baseline and 8 weeks after treatment and made statistical analysis. 【Results】 At 8 weeks after treatment, BOP, PD and AL of the three groups were improved than those in the baseline (P<0.05). BOP positive percentage of SRP+L group and L+SRP group significantly reduced compared with SRP group (P<0.05). PD of SRP+L group significantly decreased compared with SRP group and L+SRP group (P<0.05), for sites with PD=7 mm, SRP+L group was significantly decreased compared with SRP and L+SRP groups (P<0.05). AL of SRP group significantly decreased compared with SRP+L group and L+SRP group (P<0.05). 【Conclusion】 Severe periodontal treatment with Nd:YAG laser adjunct to SRP is more effective in reducing BOP and PD, and for deeper pockets PD is significantly decreased in SRP+L group, but there is no advantage in the improvement of AL.

Objective:To investigate the epidemiology and clinical characteristics of adenovirus (ADV)-caused acute respiratory tract infection among hospitalized children in Kunming, China.Methods:Clinical and laboratory data were collected from 467 children with adenovirus infection who were hospitalized from January 1, 2019 to December 31, 2019 in 6 grade A class Ⅲ hospitals in Kunming area. The basic characteristics, epidemiology, mixed infection and adenovirus genotypes of the patients were retrospectively analyzed. The patients diagnosed with adenovirus pneumonia (AP) were divided into two groups, severe AP (SAP) group and general AP(GAP) group according to the severity of illness. Mann-Whitney U test or χ 2 test was used for comparison between groups, while multivariate regression was applied to analyze the risk factors of SAP. Results:Among 15 635 hospitalized children with respiratory tract infection, 467 cases were adenovirus positive, with a detection rate of 2.99%. Of the 467 patients with adenovirus infection, 284 were male and 183 female, the age was 2.4 (1.1,3.9) years, including 44 cases (9.4%) < 0.5 years, 59 cases (12.6%) of 0.5 to<1.0 years, 176 cases (37.7%) of 1.0 to <3.0 years, 150 cases (32.1%) of 3.0 to <7.0 years, and 38 cases (8.1%) of 7.0 to 14.0 years. Adenovirus infection was common in autumn and winter, and the high incidence months were October to December, which accounted for 51.6% (241/467) of the whole year cases. Co-infection was detected in 226 cases (48.4%) out of 467 patients, in which one pathogen co-infection was the most frequent form (172 cases, 76.1%). Of the 262 pathogen detected 108 (41.2%) were Mycoplasma pneumoniae. In 144 of ADV-positve cases (30.8%) were taken geno-typing was done by PCR amplification, the results showed that 74 cases (51.4%) were ADV 3, 7 subtypes and 65 cases (45.1%) of ADV 1, 2,6 subtypes. Of the 467 cases of ADV infection, 320 (68.5%) were diagnosed with pneumonia, 82 (17.6%) with upper respiratory tract infection and pharyngeal tonsillitis, and 65 (13.9%) with bronchitis, laryngeal bronchitis, and asthmatic bronchitis. Among the 320 patients with AP, 56 cases were severe and 264 cases were general. Two cases (3.6%) in severe group died. Compared with the GAP group, the age was young [17 (11,42) months vs. 24 (14,44) months, Z=2.222, P=0.026], the fever duration was long [8 (5,14) days vs. 6 (3,9) days, Z=3.380, P<0.01], and the proportions of preterm birth and having underlying diseases were high [respectively 19.6% (11/56) vs. 6.1% (16/264), 26.8% (15/56) vs. 10.2% (27/264), χ 2=8.965,11.109, P<0.05] in SAP group. Referring to laboratory markers, white blood cell count, C-reactive protein, creatine kinase-MB and lactate dehydrogenase were significantly increased in SAP group as compared to GAP group(all P<0.05). Multivariate Logistic regression analysis showed that preterm birth ( OR=3.284, 95% CI 1.079-9.993, P=0.036), underlying disease ( OR=3.284, 95% CI 1.079-9.993, P=0.036), fever duration ≥10 d ( OR=2.523,95% CI 1.195-5.328, P=0.015) and C-reactive protein ≥50 mg/L ( OR=3.156, 95% CI 1.324-7.524, P=0.010) were positively correlated with the risk of SAP. Conclusions:The incidence of adenovirus infection among hospitalized children in Kunming was lower than the national level, and no outbreak occurred in 2019. Subtype 3 and 7 of ADV are the predominant strains for infection, which usually occurs in autumn and winter and mainly causes pneumonia. Premature birth, underlining diseases, long fever duration and markedly increased C-reactive protein are the risk factors for developing into severe pneumonia. This paper presents the prevalence and clinical characteristics of adenovirus infection in children at high altitude area.

Objective:To investigate the influencing factors for anastomotic leakage after transabdominal transanal total mesorectal excision.Methods:The retrospective case-control study was conducted. The clinicopathological data of 50 patients with rectal cancer who were admitted to the Renji Hospital of Shanghai Jiaotong University School of Medicine from December 2017 to November 2018 were collected. There were 34 males and 16 females, aged (60±11)years, with a range from 31 to 84 years. All the patients underwent transabdominal transanal total mesorectal excision. Observation indicators: (1) anastomotic leakage after transabdominal transanal total mesorectal excision; (2) analysis of influencing factors for anastomotic leakage after transabdominal transanal total mesorectal excision; (3) effects of learning curve on anastomotic leakage after transabdominal transanal total mesorectal excision. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers or percentages. Univariate analysis was conducted using the chi-square test, and multivariate analysis was conducted using the Logistic regression model. Results:(1) Anastomotic leakage after transabdominal transanal total mesorectal excision: of the 50 patients, 9 had postoperative anastomotic leakage, including 6 of grade A anastomotic leakage (2 patients receiving protective enterostomy), 2 of grade B anastomotic leakage, and 1 of grade C anastomotic leakage. Of the 9 patients with anastomotic leakage, there were 5 males and 4 females, aged 62 years (range, 40-75 years). The 9 patients had a body mass index of 27 kg/m 2 (range, 21-31 kg/m 2), and a distance from anastomosis to anal edge of 30 mm (range, 5-40 mm). (2) Analysis of influencing factors for anastomotic leakage after transabdominal transanal total mesorectal excision: results of univariate analysis showed that anastomotic method and protective stoma were related factors for anastomotic leakage after transabdominal transanal total mesorectal excision ( χ2=5.490, 5.456, P<0.05). Results of multivariate analysis showed that anastomotic method and protective stoma were not independent factors for anastomotic leakage after transabdominal transanal total mesorectal excision ( odds ratio=0.062, 0.460, 95% confidence interval: 0.009-1.119, 0.102-2.809, P>0.05). (3) Effects of learning curve on anastomotic leakage after transabdominal transanal total mesorectal excision: with the passing of learning curve and the use of protective stoma, 11 of the first 25 patients of learning cure underwent protective stoma and 6 had postoperative anastomotic leakage, while 20 of the last 25 patients of learning cure underwent protective stoma and 3 had postoperative anastomotic leakage. There was no significant difference in the postoperative anastomotic leakage between them ( χ2=1.220, P>0.05). Conclusion:Anastomotic method and protective stoma are related factors influencing anastomotic leakage after transabdominal transanal total mesorectal excision.

Purpose: RIOK1 has been proved to play an important role in cancer cell proliferation and migration in various types of cancers—such as colorectal and gastric cancers. However, the expression of RIOK1 in breast cancer (BC) and the relationship between RIOK1 expression and the development of BC are not well characterized. In this study, we assessed the expression of RIOK1 in BC and evaluated the mechanisms underlying its biological function in this disease context. Materials and Methods: We used immunohistochemistry, western blot and quantitative real-time polymerase chain reaction to evaluate the expression of RIOK1 in BC patients. Then, knockdown or overexpression of RIOK1 were used to evaluate the effect on BC cells in vitro and in vivo. Finally, we predicted miR-204-5p could be a potential regulator of RIOK1. Results: We found that the expression levels of RIOK1 were significantly higher in hormone receptor (HR)–negative BC patients and was associated with tumor grades (p=0.010) and p53 expression (p=0.008) and survival duration (p=0.011). Kaplan-Meier analysis suggested a tendency for the poor prognosis. In vitro, knockdown of RIOK1 could inhibit proliferation, invasion, and induced apoptosis in HR-negative BC cells and inhibited tumorigenesis in vivo, while overexpression of RIOK1 promoted HR-positive tumor progression. MiR-204-5p could regulate RIOK1 expression and be involved in BC progression. Conclusion These findings indicate that RIOK1 expression could be a biomarker of HR-negative BC, and it may serve as an effective prognostic indicator and promote BC progression.

With the increasing standardization of right colon cancer radical resection, more emphasis is put on keeping the mesentery intact along with vascular root ligation and extensive lymph nodes dissection which inevitably demands higher level of surveillance on the possible complications especially around gastrocolic trunk with large variation of tributary and complex vascular course, to achieve a successful surgical and oncological outcome. This article discusses the complex anatomy of the gastrocolic trunk and its implication in the choice of surgical approaches.

Objective : To explore the spatial distribution of occupational diseases in Guangdong Province and to provide evidence for the policy development of occupational disease prevention and control. Methods : A database of occupational disease incidence from 2009 to 2016 in Guangdong Province was built. The distribution of occupational diseases in Guangdong Province was displayed based on the geographic information system（GIS）, then spatial autocorrelation analysis and trend-surface analysis were carried out to explore the clustering areas and spatial epidemic characteristics of occupational diseases in Guangdong Province. Results : The number of cases with occupational diseases was 5 231 and was increasing year by year from 2009 to 2016 in Guangdong Province. The high-incidence areas were located in Guangzhou,Shenzhen,Foshan and Dongguan. Through global spatial autocorrelation analysis,it was found that there were spatial clustering of occupational diseases in Guangdong Province in each year（P<0.05）,and the cumulative incidence was also clustered（Moran's I=0.492,P<0.05）. The number of cases in Guangzhou,Shenzhen,Foshan and Dongguan had local spatial autocorrelation,and the local Moran's I values were 10.329,8.614,3.725 and 9.811,respectively（P<0.05）. The results of trend surface analysis showed that the overall incidence of occupational disease had a slight increase from west to east,and the Pearl River Delta region was a high-incidence area. Conclusion The incidence of occupational diseases in Guangdong Province had an obvious spatial clustering,the Pearl River Delta region was a high-incidence area.
