Gastric cancer with peritoneal metastasis (GCPM) is a common and lethal manifestation of advanced gastric cancer, with a median survival of only 5-11 months. This consensus was developed by 30 experts from Asia (China, Japan, Korea, and Singapore) using the Delphi method and the GRADE evidence grading system. A total of 29 statements were formulated, covering the diagnosis and assessment of GCPM, indications for laparoscopic exploration and NIPS (normothermic intraperitoneal and systemic treatment), treatment regimens, prevention and management of complications, criteria for conversion surgery, and postoperative intraperitoneal therapy. The consensus aims to standardize clinical practice and improve the prognosis of patients with GCPM.

Objective : To identify the main components in the extracts of different parts of Juandan Baihe (Lilium lancifolium) by ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF-MS) technology and investigate their hypoglycemic activities. Methods: The MS fragmentation pathways of the main types of compounds in Juandan Baihe (Lilium lancifolium) were studied, and the main components in the extracts were systematically identified using MS fragmentation pathways combined with MS mining technology. Based on the hyperglycemia male mouse model [specific pathogen free (SPF)-grade Kunming mice] induced by streptozotocin (intragastric administration of 80 mg/kg for 3 d), the hypoglycemic effects of extracts of Juandan Baihe (Lilium lancifolium) roots, stems, corms, leaves, and flowers were evaluated by measuring the changes of blood glucose, daily water consumption, daily food intake, and body weight. Result: The MS fragmentation pathways of regalosides, dioscins, phenylpropanoids, flavonoids, and chlorogenic acids in Juandan Baihe (Lilium lancifolium) were clarified, and a mining method for compounds in this plant was constructed. A total of 58 compounds, including 6 chlorogenic acids, 14 regalosides, 13 phenylpropanoids, 5 flavonoids, and 20 dioscins, were identified from the roots, stems, corms, leaves, and flowers of Juandan Baihe (Lilium lancifolium). Among them, 30 compounds were reported for the first time from this plant. The root and corm extracts demonstrated significant hypoglycemic activities by reducing blood glucose levels from 23.76 ± 1.21 and 24.29 ± 1.35 mmol/L to 17.21 ± 1.23 and 18.78 ± 1.49 mmol/L, respectively (P < 0.05). The roots and corms extracts could also attenuate the symptoms of polydipsia (P < 0.01), polyphagia (P < 0.05), and weight loss caused by diabetes. Conclusion This study clarifies that the roots of Juandan Baihe (Lilium lancifolium) are rich in regalosides and dioscins for the first time, and have significant hypoglycemic activities, providing the foundation for the comprehensive utilization of this plant and the development of hypoglycemic drugs.

Objective:To explore the effect of different HER2 expression levels and gene amplification on the efficacy of immunotherapy in metastatic urothelial carcinoma (UC).Methods:The clinical data of 77 patients with metastatic UC who received immunotherapy from June 2017 to April 2021 after failure to the previous chemotherapy were analyzed retrospectively, including 49 males and 28 females with the median age of 62 years. The primary tumors located in bladder in 28 cases (36.4%), renal pelvis in 25 cases (32.5%) and ureter in 24 cases (31.2%). The common metastatic sites included: lymph nodes (n = 45, 58.4%), lung (n = 40, 51.9%), bone (n = 20, 26.0%) and liver (n = 16, 20.8%). 27 patients with bladder UC received surgery on the primary tumors including radical cystectomy (n = 18), partial cystectomy (n = 4) and transurethral resection (n = 5). 43 patients with renal pelvis or ureteral UC received surgery on the primary tumors including radical nephroureterectomy (n = 38), local resection (n = 3) and palliative resection (n = 2). Postoperative intravesical chemotherapy was performed in 15 cases, adjuvant radiotherapy was performed in 6 cases. 3 patients who emerged postoperative bladder recurrence received local radiotherapy. 7 patients received radiotherapy and 1 case received microwave ablation to their metastatic sites. All patients had received first-line chemotherapy and 30 patients (40.0%) had received at least second-line treatment including 70 cases (90.9%) with platinum containing chemotherapy. All 77 patients received anti-PD-1 treatment. 38 patients received sequential regimen after failed to the anti-PD-1 therapy, including antibody-drug conjugate (n = 17), chemotherapy (n = 18) and chemotherapy combined with anti-angiogenesis drugs (n = 12). Immunohistochemical (IHC) staining was used to detect the expression level of HER2 protein in the tumor tissues (74 cases from primary tumors and 3 cases from metastatic tumors) obtained from the initial diagnosis. For patients with HER2 IHC (+ + ), the copy number (CN) of HER2 gene was detected by next-generation sequencing (NGS). HER2 copy number amplification [CN (+ )] was defined as CN ≥ 4, and HER2 copy number non-amplification [CN(-)] was defined as CN < 4. HER2 IHC (0) was defined as HER2 negative, IHC (+ ) or IHC (+ + ) / CN (-)was defined as HER2 low expression, while IHC (+ + ) / CN(+ ) and IHC (+ + + ) were defined as HER2 high expression. Chi-square test or Fisher exact test were used to evaluate the correlation between HER2 expression and objective response rate (ORR) after anti-PD-1 treatment. Kaplan-Meier method and log-rank test were used to compare the differences of median progression free survival (PFS) and overall survival (OS) under different HER2 expression status.Results:All the 77 patients received a median of 11 (range: 2 - 45) doses of anti-PD-1 treatment with a median duration of treatment of 6.4 (range: 1.5 - 47.8) months and the ORR was 33.8% (26/77). The median follow-up time was 30.9 months. The overall median PFS time was 5.8 (95% CI: 3.0 - 8.6) months and the median OS time was 23.6 (95% CI: 8.5 - 38.7) months. HER2 IHC tests were performed in 77 patients. HER2 IHC levels of (0), (+ ), (+ + ) and (+ + + ) were found in 33 (42.9%), 19 (24.7%), 20 (26.0%) and 5 (6.5%) patients, respectively. HER2 copy number was detected in 20 patients with IHC (+ + ), while 1 CN(+ ) and 19 CN(-) were found. The ORR of HER2 negative, low expression and high expression patients were 42.4% (14/33) vs. 31.6% (12/38) vs. 0 (0/6) ( P = 0.08), respectively. The median PFS of the three groups were 11.0 months, 3.7 months and 1.8 months, respectively, with significant differences in overall and pairwise comparison( P=0.001). The median OS of patients with HER2 negative and low expression after anti-PD-1 treatment were 23.6 months and 22.7 months, respectively, while the median OS of patients with HER2 high expression had not been reached, with no significant difference in the overall comparison ( P=0.623). Conclusions:For patients with metastatic UC received anti-PD-1 treatment, the PFS of patients with high HER2 expression was significantly worse than that of patients with low or negative HER2 expression. HER2 expression may have potential value in predicting the efficacy of immunotherapy for metastatic UC who failed the previous chemotherapy, which needs further research.

Objective:To investigate the effects of anterolateral wide pedicled double dynamic flap of the calf in repair of soft tissue defects of mid-and forefoot.Methods:From September 2015 to Septemler 2020, 15 cases with severe soft tissue defects of mid-and forefoot were repaired with the anterolateral wide pedicled double dynamic flap of the calf. There were 11 males and 4 females with an average age of 37(range, 22-53)years old. Of the 15 cases, the defects were caused by traffic accident in 6 cases and objects smash in 9 cases. Three cases were simple soft tissue defect, and 12 cases combined with fracture or dislocation and bone defect. The size of soft tissue defects ranged from 4 cm×5 cm to 7 cm×12 cm. All wounds of donor sites were repaired by skin grafting. All patients entered follow-ups at the outpatient clinic or through WeChat. The appearance of flaps and limb recovery were recorded after surgery.Results:All cases followed-up for 6-24 (mean, 16) months. Two days after surgery, 1 case had flap swelling and cyanosis, which was improved after pedicle suture removal and surface bloodletting. The pedicle of the flap was slightly bloated in 4 cases, and the texture and appearance were good in 11 cases. The ankle function of all cases recovered satisfactorily. The ranges of ankle motion were 15°-20° for dorsiflexion and 30°-40° for plantar flexion. The donor site healed well and all the skin grafts survived.Conclusion:The anterolateral wide pedicled double dynamic flap of the calf is one of the ideal flaps for repairing the soft tissue defects of the mid-and forefoot with reliable blood supply, sufficient venous return, simple operation and no require a vascular anastomosis.

BACKGROUND: The femoral intramedul ary guides in total knee arthroplasty require high precision, complex operation, it is very important for prosthesis and joint function to choose more precise positioning method and determine the correct needle point. OBJECTIVE: To study the effect of needle point position on prosthesis arrangement when applying different femoral intramedul ary guides methods in total knee arthroplasty. METHODS: Total y 80 patients who received the treatment of total knee arthroplasty in Changshu No.1 People’s Hospital from January 2012 to July 2015 were selected and divided into test and control groups according to random number table (n=40/group). The patients in the test group accepted CT scan for femoral intramedul ary guides. The theoretical position of femoral intramedul ary guides entry point was marked using radiographic parameters. In the control group, the traditional total knee arthroplasty technology was used to mark the entry point of femoral intramedul ary guides. The needle point position when applying different femoral intramedul ary guide methods was observed. The effect of femoral intramedul ary guides on prosthesis arrangement in total knee arthroplasty was discussed. RESULTS AND CONCLUSION: Compared with the control group, the distance from entry point to femoral anatomic line on positive and lateral X-ray film in the test group was shorter, femoral prosthesis lateral angle and physiological valgus angle were closer to the theoretical value, distance from intersection of femur axis and femoral condyle to block center was shorter; the differences were statistical y significant (P < 0.05). These results demonstrate that compared with the traditional two-dimensional intramedul ary positioning, the needle point position of three-dimensional CT scan stimulative positioning is more accurate. The location more concentrates on within intercondylar fossa 2-5 mm, more front of intercondylar fossa 3-10 mm, three-dimensional CT scan stimulative positioning is a reliable choice for femoral intramedul ary guides.

There are 13 members of the Let -7 miRNAs family which is regarded as tumor suppressor gene, locating in nine different chromosome loci. Lin28 acts as negative regulatory factor of miRNA biological recurrence. By selectively blocking the processing synthesis of the Let-7 miRNAs family, Lin28 block the inhibition effect of miRNA of proto-oncogenes and interact with RNA helicase to enhance gene translation at the same time. By not quite clear mechanism, an up-regulation of Let-7 inhibits the expression and function of Lin28. In more and more studies of human tumor, Lin28/Let-7 axsis was proved to be important significance of the tumor's occurrence and development. In this paper, we research briefly the recent progress of the molecular mechanism and related influence factors of ILin28/Let-7 axsis.

BACKGROUND:Total knee arthroplasty mainly used fixed platform, but more and more movable platform was selected year by year in the clinic. Rotary platform theoretical y can apparently improve the curative effects, but it has not been verified in the clinic.
OBJECTIVE:To summarize the design characteristics and clinical results of Gemini MKII (Link, Germany) rotary platform.
METHODS:From January 2004 to January 2009, 108 patients (119 knees) including 31 males and 77 females were treated with total knee arthroplasty by using Gemini MKII system. There were 97 unilateral cases and 11 bilateral cases at the first stage of replacement. Preoperative diagnosis:1 case of hemophilic arthritis, 1 case of venereal Charcot’s disease, 8 cases of post-traumatic arthritis, 11 cases of rheumatoid arthritis, and 87 cases of degenerative osteoarthritis. The prosthesis was fixed with bone cement. None received patel ar replacement. RESULTS AND CONCLUSION:None experienced infection, femoral condyle fracture or nerve and vascular damage. Except bilateral replacement, the average operation time of unilateral replacement was (56±13) minutes. Average postoperative hemoglobin decreased (25±5) g/L. After replacement, hemoglobin maintained over 100 g/L in 83 patients (86%), without blood transfusion. Knee joint score and function score recovered to (92.0±4.7) points and (90.3±6.8) points at half years after replacement, and became (94.4±3.2) points and (91.6±5.9) points during final fol ow-up, which was significantly improved as compared with that pre-replacement (P<0.01). No revision surgery should be done for lining prolapse or spin out, osteolysis and prosthesis loosening. These results indicated that the early and midterm results of Gemini MKII rotating-platform prosthesis were satisfactory, but the long-term results remain to be confirmed.

Objective To analysis the malignant performance characteristics of tumor stem cell-like side popula-tion cells in patients with cervical cancer. Methods The cervical cancer cells were obtained from surgical resection tumor tissue. The tumor stem cell-like side population cells were isolated by flow cytometry. The cell growth curve was drawn by MTT assay. The invasion ability of tumor cells was compared by transwell assay. The clonogenic capacity was detected by clone formation in soft agar. The expression level of ABCG2 protein, a drug-resistant gene, was detected by immunofluores-cence method. Finally, these cells were transplated into the subcutaneous of de thymus mice. The rate of tumor formation was compared between groups. Results The results from flow cytometry assay showed the percentage of cervical cancer stem cell-like side population cells was 1.39%. Compared with the non-side population cells, the side population cells grow quickly, showed the enhanced invasion ability and colony forming ability. There was more high expression level in ABCG 2 protein of side population cells. The tumor form rate was 100%(10/10) in the side population cells and the non-side popula-tion cells was 20%(2/10). Conclusion The cervical cancer stem cell-like side population cells have more malignant perfor-mance characteristics than that of non-side population cells, which maybe a core target for cancer gene therapy in the future.
