Objective:To compare the early therapeutic effects of internal fixation with percutaneous minimally invasive hollow nail assisted by electromagnetic navigation robot and guided by C-arm in the treatment of Tile type C pelvic fracture.Methods:A retrospective cohort study was conducted to analyze the clinical data of 32 patients with Tile type C pelvic fracture admitted to Weihai Central Hospital from January 2020 to March 2022, including 18 males and 14 females; aged 36-60 years [(44.1±3.9)years]. Among them, 17 patients were treated with internal fixation with percutaneous minimally invasive hollow nail assisted by electromagnetic navigation robot (electromagnetic navigation group), and 15 with internal fixation with percutaneous minimally invasive hollow nail guided by C-arm (C-arm guidance group). Operative time, intraoperative blood loss, sacroiliac screw placement time, pubic branch screw placement time, ambulation time and fracture healing time were compared between the two groups. Visual analog scale (VAS), Majeed function score and complication rate at 1 day, 6 months, 12 months after surgery and at the last follow-up were compared between the two groups.Results:All the patients were followed up for 12-24 months [(15.4±0.5)months]. The operative time and intraoperative blood loss in the electromagnetic navigation group were (42.0±2.5)minutes and (10.9±2.6)ml, shorter or less than (50.0±3.5)minutes and (14.9±3.1)ml in the C-arm guidance group (all P<0.01). The placement time of sacroiliac screw and pubic branch screw in the electromagnetic navigation group was (12.4±0.2)minutes and (10.1±0.3)minutes, shorter than (15.3±0.3)minutes and (13.2±0.3)minutes in the C-arm guidance group (all P<0.01). The ambulation time was (3.2±0.4)weeks in the electromagnetic navigation group, earlier than (3.5±0.4)weeks in the C-arm guidance group ( P<0.05). There was no significant difference in fracture healing time between the two groups ( P>0.05). VAS scores of the electromagnetic navigation group were (4.4±0.3)points and (1.1±0.1)points at 1 day and 6 months after surgery respectively, lower than those of the C-arm guidance group [(4.8±0.4)points and (1.2±0.3)points] ( P<0.05 or 0.01). Majeed function scores of the electromagnetic navigation group were (37.3±1.1)points and (88.5±1.4)points at 1 day and 6 months after surgery respectively, higher than those of the C-arm guidance group [(30.7±4.2)points and (82.6±1.8)points] (all P<0.01). There were no significant differences in VAS and Majeed scores at 12 months after surgery and at the last follow-up between the two groups (all P>0.05). There was no significant difference in the incidence of postoperative complications between the two groups ( P>0.05). Conclusion:Compared with C-arm guidance, electromagnetic navigation robot-assisted internal fixation with percutaneous minimally invasive hollow nail for Tile type C pelvic fracture can reduce operative time and intraoperative blood loss, shorten screw placement time and ambulation time, relieve pain and improve functional recovery at early stage.

Objective: To investigate the origin of infection and risk factors of a case with SARS-CoV-2 infection associated with overseas countries in the Ningbo-Zhoushan Port, Zhejiang Province, so as to provide the evidence for improving the COVID-19 control measures at ports. Methods: Ningbo Center for Disease Control and Prevention ( CDC ) and Beilun CDC conducted case finding and epidemiological surveys immediately after being informed. The general information, history of vaccination and the travel during the latest 14 days were collected from the positive case, and all close contacts were tracked. Saliva samples were collected for SARS-CoV-2 nucleic acid testing and whole-genome sequencing, and the sequencing results were aligned with the GISAID's EpiCoV database. The origin of infection and transmission route of the positive case was investigated. Results: A case was identified positive for SARS-CoV-2 nucleic acid during company M's routine screening in the Ningbo-Zhoushan Port on August 10, 2021, and was confirmed positive for SARS-CoV-2 nucleic acid by Beilun CDC and Ningbo CDC on August 11. Whole-genome sequencing showed SARS-CoV-2 B.1.617.2 ( Delta ) variant, which shared the highest homology with the virus sequence uploaded by Russia on June, 2021 ( Russia/MOW-RII-MH27356S/2021 ). The case was a bundling worker for overseas container ships, and reported communicated with foreign boatmen and contacted materials without protected interventions on the SINOKOR AKITA Container Ship between August 4 and 5, 2021. This ship anchored at Vladivostok, Russia from July 27 to 29, anchored at Ningbo Harbor on August 4, and departed on August 5. Then, 11 boatmen from this ship were tested positive for SARS-CoV-2 nucleic acid on August 8. One asymptomatic case was reported in this epidemic; 254 close contacts and 617 secondary close contacts were identified, and all were tested negative for SARS-CoV-2 nucleic acid. No new cases with SARS-CoV-2 infections were detected until August 25, 2021, and the emergency response was therefore terminated. Conclusions The infection was a sporadic COVID-19 epidemic associated with overseas countries, which was caused by Delta variant infection through contacts with foreign boatmen or materials by a bundling worker in Ningbo-Zhoushan Port; fortunately, no epidemic spread occurred. Intensified closed-loop management and increased frequency of SARS-CoV-2 nucleic acid test among high-risk populations, and improving the precision and rapid emergency treatment of COVID-19 epidemics are required for the containment of COVID-19 at ports.

Objective:To investigate the effect of a short hairpin RNA (shRNA) targeting epidermal growth factor receptor (EGFR) combined with sirolimus on proliferation and apoptosis of the human cutaneous squamous cell carcinoma cell line Colo-16, and to explore underlying mechanisms.Methods:Cultured Colo-16 cells were divided into 5 groups: normal cell group receiving conventional culture and treatment with phosphate-buffered saline (PBS) , negative control group transfected with a shRNA-NC-expressing plasmid and treated with PBS, sirolimus group receiving conventional culture and sirolimus treatment, EGFR shRNA group transfected with an EGFR shRNA-expressing plasmid and treated with PBS, and combined group transfected with an EGFR shRNA-expressing plasmid and treated with sirolimus. Methyl thiazol tetrazolium (MTT) assay was performed to evaluate cellular proliferative activity in the above groups from 24 to 96 hours, and flow cytometry to detect cell apoptosis after 48-hour treatment. Semiquantitative RT-PCR was conducted to determine the mRNA expression of Bcl-2 and Bax, and Western blot analysis to determine the expression of apoptosis-related proteins cleaved caspase-3, cleaved caspase-9, Bcl-2, Bax, cell proliferation-related proteins phosphorylated mammalian target of rapamycin (p-mTOR) , phosphorylated protein kinase B (p-AKT) , phosphorylated 70-kDa ribosomal protein S6 kinase (p-P70S6k) , and cyclin D1. Comparisons among groups were carried out by using one-way analysis of variance, and multiple comparisons between 2 groups by using Student-Newman-Keuls q test. Results:MTT assay showed that the proliferative activity of Colo-16 cells was significantly lower in the sirolimus group, EGFR shRNA group and combined group during 24 - 96 hours than in the normal cell group (all P < 0.05) , and higher in the combined group than in the sirolimus group and EGFR shRNA group at 24-96 hours (all P < 0.001) , and there was no significant difference in the cellular proliferative activity at any time points between the normal cell group and negative control group (all P > 0.05) . Flow cytometry showed that the apoptosis rate was significantly higher in the sirolimus group, EGFR shRNA group and combined group (9.52% ± 0.25%, 12.65% ± 0.23%, 19.81% ± 0.31%, respectively) than in the normal cell group (3.33% ± 0.18%, q = 60.07, 78.08, 122.81, respectively, all P < 0.001) and negative control group (3.42% ± 0.19%, q = 59.90, 77.91, 122.64, respectively, all P < 0.001) , and was highest in the combined group. As RT-PCR and Western blot analysis revealed, the sirolimus group, EGFR shRNA group and combined group showed significantly decreased mRNA expression of Bcl-2 and protein expression of cyclin D1, p-AKT, p-mTOR, p-P70S6K and Bcl-2, but significantly increased mRNA expression of Bax and protein expression of cleaved caspase-3, cleaved caspase-9 and Bax compared with the normal cell group (all P < 0.05) . Compared with the sirolimus group and EGFR shRNA group, the combined group showed significantly decreased mRNA expression of Bcl-2 and protein expression of cyclin D1, p-AKT, p-mTOR, p-P70S6K and Bcl-2 (all P < 0.05) , but significantly increased mRNA expression of Bax and protein expression of cleaved caspase-3, cleaved caspase-9 and Bax (all P < 0.01) . Conclusion:EGFR shRNA and sirolimus exerted a synergistic effect in inhibiting the proliferation and promoting the apoptosis of Colo-16 cells, which may be related to the inhibition of the phosphoinositide 3-kinase (PI3K) /AKT/mTOR pathway.

Objective To investigate the inhibitory effect of apigenin-7-o-glucoside (AGL) on the viability of Huh7 cells and tumor growth in Huh7-xenograft tumor nude mice. Methods CCK-8 was used to detect the proliferation inhibitory effect and the half inhibitory concentration of AGL on Huh7 cells. The mitochondrial membrane potential measurement was used to analyze the early apoptosis of Huh7 cells after AGL treatment. Flow cytometry was used to analyze the effect of AGL on Huh7 cell apoptosis, and Western blot was used to explore the expression level of the proteins associated with apoptosis and inflammation, as well as the possible related mechanism. In Huh7-xenograft tumor nude mice, vernier caliper was used to measure tumor volume to analyze the effect of AGL on tumor growth rate. HE staining was used to observe the pathological state of mouse organs, and the inflammation-related factors in serum were detected with ELISA. Results After Huh7 cells were treated with AGL, the mitochondrial membrane potential reduced, the content of ROS increased and the apoptosis rate was increased to 25.23% by 50 μmol/L AGL treatment; while the expression levels of Bax, Bad, Cleaved Caspase-3 and Cleaved Caspase-9 increased, and the expression levels of Bcl2 and Bcl-x^L decreased, the phosphorylation level of NF-κB, IKKα/β and IκBα decreased; the tumor growth rate decreased, the serum IL-6 and TNF-α levels significantly decreased, while the IL-2 and IL-10 levels increased. Conclusion AGL could promote the apoptosis of Huh7 cells and relieve the tumor development in Huh7-xenograft tumor nude mice, which may be related to the NF-κB pathway.

After treatment, the scores of cough, phlegm, shortness of breath, pale face, fatigue, spontaneous perspiration, poor appetite in the observation group were significantly lower than those in the control group (t value were 10.008, 11.529, 11.778, 12.043, 11.309, 10.128, 11.008, P<0.01), and elapsed time of gasping, antifebrile time, disappear time of lung moist crackles, absorption time were significantly earlier than the control group (t value were 15.121, 10.099, 18.441, 14.310, P<0.01). After 2 week’ treatment, the scores of symptoms of deficiency of lung-spleen Qi in the observation group were significantly lower than those of control group (P<0.01). Compared with the control group, the duration of wheezing and antipyretic, duration of lung dampness and chest X-ray absorption in the observation group were significantly decreased (P<0.05). The total effective rate of the observation group was 97.52%, which was significantly higher than the control group 92.67% (P<0.05). After 2 week treatment, the CD4⁺ (41.03% ± 4.55% vs. 33.52% ± 3.95%, t=14.011) in the observation group was significantly higher, CD8⁺ (22.71% ± 2.83% vs. 26.65% ± 3.05%, t=10.061) was significantly lower than the control group, serum levels of IL-6 (28.13 ± 3.63 ng/L vs. 40.09 ± 4.61 ng/L, t=14.890) and IL-8 (21.41 ± 2.75 ng/L vs. 29.05 ± 3.61 ng/L, t=11.439) were significantly lower than the control group (P<0.01). Conclusions Massage combined with microwave therapy for the Children's bronchial pneumonia with deficiency of lung-spleen Qi syndrome can promote the improvement of symptoms, enhance the efficacy, increase the immune function and reduce inflammation level.

Objective To investigate the effect of the endoscopic surveillance system in irrigating fluid absorption and bleeding during transurethral resection of the prostate.Methods In vitro trials,we simulated the fluid absorption and bleeding in the operation by using self-developed endoscopic surveillance system from January 2013 to June 2013.Continuous irrigation of 5 ％ mannitol solution,we extracted 5 times irrigating fluid (each time 100 ml and a total of 500 ml) in the process of irrigation and recorded absorption measurements of every time extraction rinses.At the same time,we dripped human whole blood 5 times(each time 5 ml and a total of 25 ml) in the process of irrigation and recorded the bleeding measurements.The above process was repeated three times to detect the accuracy and consistency of the endoscopic surveillance system.In clinical trials,50 cases of BPH were monitored in surgery and the biochemical index,hemodynamics,irrigating fluid absorption and bleeding were compared from October 2016 to April 2017.The included criteria contained as follow:the age of patients should be more than 50 years.The transabdominal ultrasound showed that the volume of prostate should be more than 60 ml.The maximal uroflowmetry should be less than 15ml/s.The IPSS scores should be more than 8.Based on the operative time,two groups (＜60 min and ≥ 60 min) were classified.Results We developed the endoscopic surveillance system which is original in the world.In vitro trials,the average irrigating fluid were (100.60 ± 2.07) ml,(201.00±3.39) ml,(302.00±4.67) ml,(403.60±4.39) ml and (502.40 ±7.57) ml;and the average bleeding were (5.06 ± 0.11) ml,(10.10 ± 0.16) ml,(15.04 ± 0.15) ml,(20.06 ± 0.11) ml and (25.10 ± 0.16) ml.No significant difference was observed in all groups (P ＞ 0.05).In clinical trials,we compared some preoperative and postoperative indexes.The average blood oxygen saturation were (94.46 ± 2.49) ％ and (92.39 ± 2.77) ％ (P ＜ 0.01),the average Serum sodium ion concentration were (141.05 ± 2.52) mmol/L and (138.06 ± 4.27) mmol/L(P ＜ 0.01),the average HGB were (143.50 ± 13.43) g/L and (137.04 ± 14.25) g/L(P ＜ 0.01).The average HCT were (42.05 ± 4.09) ％ and (137.04 ± 14.25) ％ (P ＜ 0.01).The average HR were (77.9 ± 7.6) beats per minute and (77.93 ± 6.93) beats per minute (P＞0.05).The MAP were (90.32 ± 9.75) mmHg and (91.07±8.96)mmHg(P＞0.05).The average serum potassium ion concentration were (4.13 ± 0.53) mmol/L and (4.09 ± 0.37) mmol/L (P ＞ 0.05).The average irrigating fluid absorption of the group less than 60 minutes and the group equal or more than 60 minutes were (401.83 ± 279.23) ml and (885.25 ± 367.68) ml (P ＜ 0.01).The average blood loss were (64.10 ±47.47) ml and (158.40 ± 65.22) ml(P ＜0.01).The preoperative and postoperative hemodynamic,blood biochemical and hematology showed difference in our trials.Irrigating fluid absorption and blood loss were positively associated with operation time.Conclusions The endoscopic surveillance system was safety and accuracy.It can offer real-time monitoring data and alarm mechanism for the surgeons that possibly improve operation safety.

OBJECTIVETo compare the difference in CT manifestations between primary colorectal mucinous adenocarcinoma and signet ring cell carcinoma in order to improve radiologic diagnosis.

METHODSClinicopathological data and CT findings of 109 patients with colorectal mucinous adenocarcinoma and 46 patients with primary colorectal signet-ring cell carcinoma confirmed by surgery and pathology from March 2008 to February 2015 in the Tumor Hospital of Yunnan Province were retrospectively collected. Differences in age, gender, tumor location, length and thickness of the involved intestinal wall, thickening pattern of the intestinal wall, lesion density, calcification, contrast-enhanced form, peri-intestinal invasion, occurrence of intestinal obstruction and metastasis of other organs were compared between the two groups.

RESULTSAmong 109 patients with colorectal mucinous adenocarcinoma, 68 were men and 41 were women with a mean age of (56.8±15.4) years. Among 46 patients with primary colorectal signet-ring cell carcinoma, 26 were men and 20 were women with a mean age of (42.9±15.6) years. Compared with mucinous adenocarcinoma group, signet-ring cell carcinoma group showed more concentric bowel-wall thickening[93.5%(43/46) vs. 81.6%(89/109), χ=9.19, P=0.030], higher lesion density [(42.0±3.0) Hu vs. (28.5±1.5) Hu, t=37.30, P=0.000], more marked enhancement [54.3%(25/46) vs. 12.8%(14/109), χ=35.21, P=0.000], less vast-low-density region in enhanced CT imaging[2.2%(1/46) vs. 45.0%(49/109), χ=73.31, P=0.000] and more severe peri-intestinal invasion [41.3% (19/46) vs. 17.4%(19/109), χ=10.25, P=0.006]. Calcification was found in 18.3%(20/109) of mucinous adenocarcinoma cases, but was not found in signet-ring cell carcinoma cases (χ=9.69, P=0.002). Target ring sign in contrast-enhanced scan was observed in 15.2%(7/46) of signet-ring cell carcinoma cases, while in none of mucinous adenocarcinoma cases (χ=17.37, P=0.000). There were no statistically significant differences in lesion location, length and thickness of the involved intestinal wall, occurrence of intestinal obstruction, lymph node metastasis, liver or peritoneum metastasis between two groups(all P>0.05).

CONCLUSIONSSignet-ring cell carcinoma is often found in younger patients, whose CT manifestation is characterized by the target ring sign in contrast-enhanced scan, while primary colorectal mucinous adenocarcinoma is often in older patients, whose CT manifestation is characterized by calcification in unenhanced scan and low density region in enhanced CT show.
