There were 65 males and 71 females with an average age of 46.07±13.37 years (range 13-73 years). There were 120 primary cases and 16 secondary cases, of which 109 cases were ordinary chondrosarcoma (7 cases with pathological differentiation grade I, 83 cases with grade II. There were 109 cases of common type chondrosarcoma (7 cases of pathological differentiation grade I, 83 cases of grade II, 19 cases of grade III), 21 cases of dedifferentiated chondrosarcoma, 3 cases of mesenchymal type, 2 cases of clear cell type, 1 case of mucinous type; 12 cases of malignant degeneration of multilocular chondrosarcoma of bone; 104 cases of Enneking staging stage IB, 32 cases of stage IIB. According to the pelvis zone classification, there were 14 cases of pelvic zone I, 1 case of zone II, 13 cases of zone III, 16 cases of zone I+II, 16 cases of zone I+IV, 47 cases of zone II+III, 25 cases of zone I+II+III, 25 cases of zone I+II+III, 4 cases of zone I + II + III + IV. All cases were classified as intracapsular, marginal, or wide resection according to the resection boundary classification. There were 45 cases in computer-navigated surgery (navigated group) and 91 cases in non-navigated surgery group. The demographic data, preoperative tumor staging, surgical characteristics, surgical boundary classification, oncological indexes, reconstruction methods, postoperative complications, and bone and soft tissue tumor function score (Musculoskeletal Tumor Society score, MSTS) were compared between the two groups.Results:No surgical complications related to the computerized navigation system occurred in the navigation group. The postoperative follow-up time was 68.56±37.82 months (range 6-197 months) and 76.85±52.60 months (range 5-225 months) for the navigation and non-navigation groups, respectively. The MSTS was 25.43±2.85 and 24.56±4.19 points in the navigation and non-navigation groups, respectively, with no significant difference ( t=1.191, P=0.237). There were 10 cases of marginal resection and 35 cases of wide resection in the navigation group, and 12 cases of intracapsular resection, 32 cases of marginal resection and 47 cases of wide resection in the non-navigation group with significant difference (χ 2=10.977, P=0.004). There were 4 cases (8.9%, 4/45) of local recurrence after surgery in the navigation group and 20 cases (21.9%, 20/91) in the non-navigation group, with significant difference (χ 2=4.040, P=0.046). There were 2 cases of final amputation and 2 cases of re-excision with recurrence in the navigation group and 6 cases of final amputation and 14 cases of re-excision in the non-navigation group. Distant metastases occurred in 3 cases (7%, 3/45) in the navigation group and 18 cases (20%, 18/91) in the non-navigation group wtih significant difference (χ 2=4.478, P=0.034). The five-year postoperative survival rates of the navigation and non-navigation groups were 93.3% and 72.6%, and the three- and five-year progression-free survival rates were 91.1% and 84.4% and 74.8% and 62.7%, respectively, with significant differences (χ 2=5.081, P=0.024; χ 2=6.800, P=0.009). The five-year survival rate of stage IB tumors was 96.7% in the navigation group and 84.5% in the non-navigation group with significant difference (χ 2=3.897, P=0.048); the five-year survival rate of stage IIB tumors was 75.0% in the navigation group and 35.0% in the non-navigation group with no significant difference ( P>0.05). Postoperative complications included 15 cases of postoperative infection, 16 cases of deep vein thrombosis, 14 cases of double lower limb inequality, 2 cases of prosthesis dislocation, 2 cases of lymphedema, 1 case of hernia and 1 case of allograft bone resorption. There was no significant difference of complication rates between the two groups ( P>0.05). Conclusion:Computer navigation-assisted resection of pelvic chondrosarcoma was better in obtaining a safe surgical border of the tumor compared with traditional surgery, reducing the rate of local recurrence of the tumor and thus effectively improved the survival and prognosis of patients.

OBJECTIVE: To investigate short-term effectiveness and clinical application advantages of orthopedic robot-assisted resection for osteoid osteoma compared with traditional open surgery. METHODS: A retrospective analysis was conducted on clinical data of 48 osteoid osteoma patients who met the selection criteria between July 2022 and April 2023. Among them, 23 patients underwent orthopedic robot-assisted resection (robot-assisted surgery group), and 25 patients received traditional open surgery (traditional surgery group). There was no significant difference ( P>0.05) in gender, age, disease duration, lesion location and size, and preoperative visual analogue scale (VAS) score, and musculoskeletal tumor society (MSTS) score between the two groups. The surgical time, intraoperative blood loss, intraoperative lesion localization time, initial localization success rate, infection, and recurrence were recorded and compared. VAS scores before surgery and at 24 hours, 1, 3, 6, and 9 months after surgery and MSTS score before surgery and at 3 months after surgery were assessed. RESULTS: All patients completed the surgery successfully, with no significant difference in surgical time between the two groups ( P>0.05). Compared to the traditional surgery group, the robot-assisted surgery group had less intraoperative blood loss, shorter lesion localization time, and shorter hospitalization time, with significant differences ( P<0.05). The initial localization success rate was higher in the robot-assisted surgery group than in the traditional surgery group, but the difference between the two groups was not significant ( P>0.05). All patients in both groups were followed up, with the follow-up time of 3-12 months in the robot-assisted surgery group (median, 6 months) and 3-14 months in the traditional surgery group (median, 6 months). The postoperative MSTS scores of both groups improved significantly when compared to those before surgery ( P<0.05), but there was no significant difference in the changes in MSTS scores between the two groups ( P>0.05). The postoperative VAS scores of both groups showed a gradually decreasing trend over time ( P<0.05), but there was no significant difference between the two groups after surgery ( P>0.05). During follow-up, except for 1 case of postoperative infection in the traditional surgery group, there was no infections or recurrences in other cases. There was no significant difference in the incidence of postoperative infection between the two groups ( P>0.05). CONCLUSION Orthopedic robot-assisted osteoid osteoma resection achieves similar short-term effectiveness when compared to traditional open surgery, with shorter lesion localization time.

Objective:To compare the clinical efficacy and safety of Shuo Tong ureteroscopy(ST-URS) and flexible ureteroscope(FURS)combined with holmium laser lithotripsy in the treatment of upper ureteral calculi with CT numerical value ≥ 1000 HU.Methods:A retrospective analysis of the clinical data of patients of upper ureteral calculi with CT numberical value≥1000 HU in the First Affiliated Hospital of Xiamen University was made from January 2018 to November 2020.There were 61 cases treated with ShuoTong ureteroscopy holmium laser lithotripsy (ST-URS group), including 45 males and 16 females, with 40 on the left and 21 on the right, age of(48.3±12.7) years, body mass index of(24.7±2.7)kg/m 2, the diameter of stone of(1.50±0.45)cm, and the CT numberical value of(1 288.8±179.0)(1 017-1 738)HU. There were 87 cases were treated with flexible ureteroscopy holmium laser lithotripsy (FURS group), including 58 males and 29 females, with 56 on the left and 31 on the right, age of(48.5±13.0) years, body mass index of(24.1±3.8)kg/m 2, the stone diameter of(1.45±0.40)cm, and the CT numberical value of(1 311.3±188.9)(1 009-1 817)HU. There were no significant differences in gender, age, body mass index, the location of stone, the diameter of stone and the CT numberical value of stone( P>0.05)between the two groups. For ST-URS group, a rigid ureteral channel sheath and standard mirror(F7.5/11.5)were placed under direct vision, exiting the standard mirror, leaving the channel sheath, inserting a lithotripsy mirror(F4.5/6.5)and a holmium laser[Power: 8-30 W(0.4-1.0 J/20-30 Hz)], and withdrawing the stone fragments after crushing the stone by "nibbling method" . For FURS group, a hard ureteroscope(F8/9.8)was used to explore the lesion side of the ureter, inserting a guide wire and placing a soft ureteral sheath, then inserting a flexible ureteroscope(F8)for holmium laser lithotripsy, and useing a stone basket to remove larger stone fragments. Ureteral stent was routinely indwelled after the operation. On the day 1 and 1 month after the operation, imaging examinations were performed to evaluate the stone-free rate. No residual stones or the diameter of stone was ≤0.4 cm and no urinary tract infection or any symptoms were defined as stone free. The operation time, blood loss, success rate of stage Ⅰ ureteral access sheath placement, incidence of postoperative complications, stone-free rate(SFR) at 1 day after operation, SFR at 1 month after operation, postoperative hospital stay and hospitalization costs were compared between the two groups. According to the size of calculi, the 2 groups were divided into 2 subgroups(≥1.5 cm and <1.5 cm)in order to make further analysis. The operation time, stone-free rate(SFR) at day 1 after operation and SFR at 1 month after operation were compared between the two groups. Results:The operation time of the ST-URS group was shorter than the FURS group(40.10 min vs. 49.43 min, P=0.020), and the incidence of postoperative complications was lower than the FURS group[3.28%(2/61)vs. 13.79%(12/87), P=0.031]. The SFR at day 1 after operation was significantly higher than the FURS group[60.7%(37/61)vs. 25.3%(22/87), P<0.01], and the hospitalization cost was lower than that of the FURS group(27 686 yuan vs. 32 281 yuan, P<0.010). There were no significant differences in the blood loss[(4.92±9.51)ml vs.(3.95±6.04)ml, P=0.452], success rate of stageⅠureteral access sheath placement[ 96.7%(59/61)vs. 96.6%(84/87), P=1.000], SFR at 1 month after operation[81.97%(50/61) vs. 75.86%(66/87), P=0.375] and postoperative hospital stay[(2.5±1.4)d vs.(2.4±0.8)d, P=0.543] between the two groups. When the size of calculi was ≥1.5cm, the operation time of the ST-URS group was shorter than the FURS group (43.67 min vs 55.00 min), the SFR at 1 day after operation was higher than the FURS group[40.00%(12/30)vs. 9.38%(3/32)], and the above differences are all statistically significant ( P<0.05). Conclusions:Compared with the FURS, for the treatment of upper ureteral calculi with CT numerical value ≥1000 HU, the ST-URS has shorter in operative time, lower in hospitalization cost and incidence of postoperative complications and higher SFR at day 1 after operation. The ST-URS is a safe and effective surgical technique, which is superior in the treatment of larger(≥1.5 cm) stones.

Objective:To construct a scientific and feasible index system for nurses′ ability to cope with new infectious diseases based on ability-based education theory, so as to provide reference for the training of nurses′ ability to cope with new infectious diseases.Methods:After consulting domestic and foreign literaturesuch as China National Knowledge Internet, Wanfang, VIP, PubMed, Web of Science, etc. from the establishment of the database to October 2020, based on the theory of "ability-based education", taking the action framework of the theory of "life cycle of emergency" and "sudden infectious disease events proposed" by WHO as the structural framework, the index items were preliminarily constructed, and the Delphi expert consultation method was used to conduct two rounds of expert consultation for 15 experts, so as to finally establish the index system of nurses′ ability to cope with new infectious diseases.Results:The effective recovery rate of the two rounds of expert consultation questionnaires was 100.00%, and the authority coefficient was 0.930. Kendall′s concordance coefficients of two rounds of consultation experts in the tertiary indicators were 0.363, 0.304 and 0.269, respectively, with statistically significant differences (all P<0.01), and the coefficient of variation of each index was 0.000-0.167. The index system of nurses′ ability to cope with new infectious diseases included 3 primary indicators, 12 secondary indicators and 44 tertiary indicators. Conclusions:The index system of nurses′ ability to cope with new infectious diseases based on ability-based education theory is scientific, reliable and practical, which can provide reference for the training and assessment of new infectious diseases coping ability of nurses.

Objective:To observe any effect of a half palm ankle-foot orthosis and a hollow-heel ankle-foot orthosis on the gait of stroke survivors.Methods:The walking of twenty-five stroke survivors was quantified using a gait analysis system. They walked barefoot, wearing a half palm ankle-foot orthosis and wearing a hollow-heel ankle-foot orthosis. Walking speed, step frequency, duration of the swing phase on the healthy and affected sides, risk of falling and Timed Up and Go (TUG) test times were recorded and analyzed.Results:The average gait frequency when wearing the hollow-heel ankle-foot orthosis was significantly faster than that in the other two conditions. The gait asymmetry coefficient was significantly different when the subjects wore the hollow-heel ankle-foot orthosis compared with walking barefoot. Compared with being barefoot, the average TUG time was significantly shorter when wearing either orthosis and the risk of falling was significantly less. The fall risk was significantly lower when wearing the hollow-heel orthosis compared to the half palm orthosis.Conclusion:Wearing either ankle-foot orthosis can significantly correct the gait of stroke survivors and lower their risk of falling, with better effect when wearing the hollow-heel ankle-foot orthosis.

ObjectiveTo investigate the therapeutic effect of Gexia Zhuyutang on rats with endometriosis （EMT） with Qi stagnation and blood stasis syndrome and its mechanism. MethodSix female unpregnant healthy SD rats of SPF grade were randomly selected as a blank group. The rest were treated with the compound factor method to induce EMT with Qi stagnation and blood stasis syndrome in rats. After successful modeling， 30 rats from 36 rats were randomly divided into a model group， a medroxyprogesterone （0.416 mg·kg^-1） group， and low， medium， and high-dose Gexia Zhuyutang groups （4.063， 8.125， 16.25 g·kg^-1）， with 6 rats in each group. Each group was given corresponding drugs， once a day for 4 consecutive weeks. The effect of Gexia Zhuyutang on rats with EMT was observed by the pathological changes and the volume of ectopic foci. The endometrial tissues of each group were taken for hematoxylin-eosin （HE） staining to observe histopathological changes. Enzyme-linked immunosorbent assay （ELISA） was used to determine the content of interleukin （IL）-10 and IL-6 in the serum supernatant of each group. Immunohistochemistry （IHC） was used to determine the protein expressions of nuclear factor kappa B （NF-κB）， matrix metalloproteinase-9 （MMP-9）， vascular endothelial growth factor （VEGF）， and Bcl-2 related X protein （Bax） in the tissues of rats in each group. Real-time fluorescence quantitative reverse transcription polymerase chain reaction （Real-time PCR） was used to determine the mRNA expressions of NF-κB， MMP-9， VEGF， and Bax. ResultAfter treatment， the volume of ectopic foci in the low， medium， and high-dose Gexia Zhuyutang groups and the medroxyprogesterone group was significantly reduced. The pathological observation under the microscope showed that the endometrial structure of rats in the sham-operated group and the blank group was intact， glands and mesenchymal cells grew well， glandular epithelial cells were arranged tightly and neatly， the cytoplasm was abundant and highly columnar， the interstitial cells were evenly distributed， and the blood vessels were abundant and spindle-shaped. Compared with the blank group and the sham-operated group， the model group was dominated by columnar epithelium and cubic epithelium. In the model group， ectopic endometrial epithelial cells were short columnar， some were pseudo-lamellar， the cell morphology was incomplete， the number of interstitial cells and glands was reduced， some glands were round， and degenerative dysplasia was formed. Compared with the blank group， the serum content of IL-10 in the model group was decreased （P<0.05）， and the content of IL-6 was increased （P<0.05）. The model group increased the protein expressions of NF-κB， VEGF， and MMP-9 （P<0.05） and decreased the protein expression of Bax in eutopic and ectopic endometrial tissues. Compared with the model group， the serum content of IL-10 in the medium and high-dose Gexia Zhuyutang groups was increased （P<0.05）， and the content of IL-6 was decreased （P<0.05）. The protein expressions of NF-κB， VEGF， and MMP-9 in eutopic and ectopic endometrial tissues of rats in the low， medium， and high-dose Gexia Zhuyutang were decreased （P<0.05）， and the protein expression of Bax was increased （P<0.05）. Compared with the ectopic endometrium of the model group， the mRNA expressions of NF-κB， MMP-9， and VEGF in the ectopic endometrium of the medium and high-dose Gexia Zhuyutang groups were decreased （P<0.05）， and the mRNA expression of Bax was increased （P<0.05）. ConclusionGexia Zhuyutang has the effect of inhibiting the invasion of ectopic foci in rats with EMT with Qi stagnation and blood stasis syndrome， and its mechanism may be related to the intervention of immunosuppression mediated by overactivation of the NF-κB signaling pathway， the improvement of the inflammatory response， and the blocking of microvascular regeneration function.

【Objective】 To analyze the data of non-small cell lung cancer (NSCLC) gene chip using the bioinformatics method, screen differential expression genes (DEGs), and explore the biomarkers related to the prognosis of NSCLC so as to provide a new target for the treatment of NSCLC. 【Methods】 The NSCLC gene chip data were downloaded from the GEO database and the common DEGs in the two datasets were screened by GEO2R tool and FunRich3.1.3 software. The DAVID database was used in GO analysis and KEGG analysis of the DEGs. The protein-protein interaction (PPI) network was constructed using the STRING database; Cytoscape 3.8.0 software was used to select the top 20 hub genes. Then Kaplan-Meier plotter was used to analyze the prognosis of the identified hub genes, and multiple external databases were used to verify the expressions of the hub genes and their relationship with prognosis. 【Results】 A total of 159 intersect DEGs were screened from the two datasets. A total of 20 hub genes were identified via PPI network. Survival analysis and validation results from multiple external databases showed that SPP1 was highly expressed in NSCLC tumor tissues and was significantly correlated with the patients’ poor prognosis (P<0.05). The subgroup analysis showed that SPP1 might cause the poor prognosis by affecting lymph node metastasis. 【Conclusion】 SPP1 may be a biomarker for evaluating the prognosis of NSCLC patients, providing a new idea for the targeted therapy of NSCLC.

OBJECTIVE: To evaluate the efficacy and safety of hydroxychloroquine (HCQ) in the treatment of patients with moderate coronavirus disease 2019 (COVID-19). METHODS: We prospectively enrolled 30 treatment-naïve patients with confirmed COVID-19 after informed consent at Shanghai Public Health Clinical Center. The patients were randomized 1：1 to HCQ group and the control group. Patients in HCQ group were given HCQ 400 mg per day for 5 days plus conventional treatments, while those in the control group were given conventional treatment only. The primary endpoint was negative conversion rate of SARS-CoV-2 nucleic acid in respiratory pharyngeal swab on days 7 after randomization. This study has been approved by the Ethics Committee of Shanghai Public Health Clinical Center and registered online (NCT04261517). RESULTS: One patient in HCQ group developed to severe during the treatment. On day 7, nucleic acid of throat swabs was negative in 13 (86.7%) cases in the HCQ group and 14 (93.3%) cases in the control group (>0.05). The median duration from hospitalization to virus nucleic acid negative conservation was 4 (1,9) days in HCQ group, which is comparable to that in the control group [2 (1,4) days, Z=1.27, >0.05]. The median time for body temperature normalization in HCQ group was 1 (0,2) day after hospitalization, which was also comparable to that in the control group [1 (0,3) day]. Radiological progression was shown on CT images in 5 cases (33.3%) of the HCQ group and 7 cases (46.7%) of the control group, and all patients showed improvement in follow-up examinations. Four cases (26.7%) of the HCQ group and 3 cases (20%) of the control group had transient diarrhea and abnormal liver function (>0.05). CONCLUSIONS The prognosis of COVID-19 moderate patients is good. Larger sample size study are needed to investigate the effects of HCQ in the treatment of COVID-19. Subsequent research should determine better endpoint and fully consider the feasibility of experiments such as sample size.
