This paper introduces Professor HUANG Jinchang's experience in treating low anterior resection syndrome (LARS) of rectal cancer. Based on the clinical experience in treating fecal incontinence after rectal cancer surgery, Professor HUANG Jinchang proposes that the primary pathogenesis of LARS is spleen-kidney yang deficiency with internal obstruction of damp turbidity. The treatment approach should focus on strengthening the spleen, warming the kidney, and eliminating turbidity. The Baliao acupoints are specifically selected to eliminate turbidity, promote yang , facilitate the qi flow of the viscera, and regulate the opening and closing of the anus. Emphasis is placed on deep needling at the Baliao acupoints, with flexible acupoint selection based on accompanying symptoms. Additionally, moxibustion and bloodletting cupping are used to restore regular bowel movements and improve the quality of life for patients who have undergone anus-preserving surgery for rectal cancer.

Background Few studies have been conducted on the associations of dietary habits with the risks of high normal blood pressure and hypertension in employees of chemical companies in northwest China. Objective To understand the excess intakes of red meat, offal, and salt, the current status of high normal blood pressure and hypertension detection among employees of a large chemical company in Gansu, China, and to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension. Methods A large state-owned chemical enterprise in Gansu Province was selected and 914 employees were recruited by age-stratified random sampling. A set of questionnaires and health examination were adopted for the survey. χ² test was used to compare dietary habits. A logistic regression model was used to analyze the relationships between different dietary habits and the risks of high normal blood pressure and hypertension in the chemical enterprise employees after including the factors significantly different in the χ² test. Results A total of 914 workers completed the survey. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by gender, age, body mass index (BMI), and family history of hypertension (P < 0.001). The excess intake rates of red meat, offal, and salt were 25.4%, 29.0%, and 62.1%, respectively. Significant differences were found in the distribution of normal blood pressure, high normal blood pressure, and hypertension among the participants grouped by intakes of meat, offal, and salt (P < 0.001). The highest positive rate of high normal blood pressure was detected in the workers with excess intakes of offal and salt (P < 0.001). The prevalence rate of hypertension increased with higher intakes of red meat, offal, and salt (P < 0.001). After adjusting for gender, age, BMI, family history of hypertension, and other factors, the results of logistic regression showed that the risks of high normal blood pressure and hypertension in workers with excess red meat intake were 1.55 (95%CI: 1.00, 2.38) times and 2.88 (95%CI: 1.63, 5.07) times higher than those in workers with low red meat intake respectively. The risks of high normal blood pressure and hypertension in workers with excess offal intake were 1.75 (95%CI: 1.12, 2.72) times and 1.87 (95%CI: 1.01, 3.44) times higher than those in workers with no offal intake respectively. The risks of high normal blood pressure and hypertension in workers with excess salt intake were 1.80 (95%CI: 1.22, 2.65) times and 2.59 (95%CI: 1.63, 4.11) times higher than those in workers with moderate salt intake, respectively. Conclusion Excessive intakes of red meat, offal or salt are common among the chemical enterprise workers. Excess intakes of red meat, offal, and salt are risk factors for both high normal blood pressure and hypertension. The northwest chemical enterprise should further advocate a healthy and reasonable diet among employees, and propose to reduce the intakes of red meat, offal, and salt.

Objective:To explore the technical points and efficacy of gradual traction-unlocking closed reduction technique (GT-UCRT) for Tile C old pelvic fractures.Methods:From August 2012 to June 2021, 6 patients with Tile C old pelvic fracture were treated and followed up at Department of Orthopedics, The Fourth Medical Center, General Hospital of Chinese PLA. They were 4 males and 2 females with an age of (35.8±10.5) years. By Tile classification: 4 cases of type C1.2, 1 case of type C1.3, and 1 case of type C2; time from injury to surgery: 153.8 (64.3, 204.8) days. The 6 patients were treated with GT-UCRT. The time for gradual traction reduction, operation time, hospital stay, intraoperative blood loss and complications were recorded. The modified Matta score was used to evaluate the reduction quality of pelvic fractures, and the Majeed score was used to evaluate the pelvic function at the last follow-up.Results:The 6 patients were followed up for (40.3±22.9) months (from 12 to 72 months) after surgery. The time for gradual traction reduction was (26.7±4.6) days, operation time (119.2±4.6) minutes, hospital stay (11.5±2.9) days, and intraoperative blood loss (533.3±189.6) mL. By the modified Matta score, the pelvic reduction after surgery was rated as satisfactory in 5 cases and as unsatisfactory in 1 case. The length disparity between both lower limbs in the 6 patients was (6.9±1.6) cm before surgery and (1.0±0.4) cm immediately after surgery, showing a statistically significant difference ( t=11.135, P<0.001). One fracture healed 3 months after surgery and 5 fractures 6 months after surgery. The Majeed pelvic score at the last follow-up was (80.8±9.0) points for the 6 patients, yielding 2 excellent cases, 3 good cases and 1 fair case. Delayed wound healing was reported in 1 patient, calf intermuscular venous thrombosis in 2 cases, and emotional anxiety and sleep disorder in 1 patient. No new lumbosacral plexus injury was found in any patient. Conclusions:In the treatment of Tile C old pelvic fractures, since our self-designed GT-UCRT combines the advantages of Ilizarov technique and unlocking closed reduction technique, it can not only protect the lumbosacral plexus but also obtain satisfactory reduction of the fracture.

Objective:To evaluate the safety and efficacy of the technique of minimally invasive separation surgery with small incision and free hand screw placement in patients with spinal metastases.Methods:Retrospectively reviewed the clinical data of 49 consecutive patients from May 2019 to December 2019 who underwent minimally invasive separation surgery with small incision and free hand screw placement for metastatic spinal tumors. Among them, there were 21 males with an average age of 55.62±2.97 years (range: 26-75 years) and 28 females with an average age of 52.50±1.76 years (range: 34-72 years). For patients who have primary tumor history with multiple metastases, routine pre-operative biopsy is not required; but for patients whose primary tumor is unknown and who have no history of tumor, pre-operative biopsy diagnosis is required. Before operation, Karnofsky Performance status (KPS) scoring system was used to evaluate the general condition of patients, Spinal Instability Neoplastic Score (SINS) scoring system was used to evaluate the spine stability, epidural spinal cord compression (ESCC) grading system was performed to access the degree of spinal cord nerve compression, and Frankel grading system was used to evaluate the neurological function. For patients who meet inclusion and exclusion criteria ware performed for decompression and internal fixation by a minimally invasive separation surgery with small incision and free hand screw placement. The demographic, neurological function, complications and perioperative data were collected and analyzed, including pre-operation neurological function, operation time, intraoperative blood loss, postoperative suction drainage, drainage tube extraction time, complications rates, hospital stay, and assessment of neurological recovery at 4 weeks after surgery.Results:Preoperative coil embolization was performed in 1 patient with kidney cancer. The mean intraoperative blood loss was 748.60±79.39 ml. Comparison of intraoperative blood loss of 12 rich blood supply (liver cancer, kidney cancer, thyroid cancer) and 37 poor blood supply spine metastases (970.80 ml vs 676.50 ml) was not statistically significant ( P>0.05). The average operation time was 213.40±9.87 min. The operation involved 1 segment was performed in 41 patients (83.67%) and 8 patients had separation of 2 or more segments. The post-operative drainage before discharge was 494.02±63.30 ml. The average drainage tube retention time was 4.50±0.26 d and the average length of hospital stay was 7.35±0.38 d. The post-operative hospitalization was 5.31±0.29 d. 79.59% of patients had the neurological functions of Frankel grade C and D before surgery and 95.92% of patients exhibited stable and improved function at 4 weeks after surgery which was significantly improved comparing with that before surgery ( P<0.05). The complications occurred were dural rupture (1 case), infection (1 case) and hematoma (1 case). Comparison:The minimally invasive separation surgery with small incision and free hand screw placement could achieve less trauma, low complications rate, rapid postoperative recovery. It is also comparable to the traditional open separation surgery in terms of spinal stability and improvement of neurological functions. It is an excellent alternative for patient with spinal metastases.

Objective: To explore the association between fatty liver and type 2 diabetes mellitus (T2DM) in the baseline-population of Jinchang cohort study. Methods: Data from all the participants involved in the baseline-population of Jinchang cohort study was used, to compare the risks of T2DM in fatty liver and non fatty liver groups and to explore the interaction between family history or fatty liver of diabetes and the prevalence of T2DM. Results: Among all the 46 861 participants, 10 574 were diagnosed as having fatty liver (22.56%), with the standardized rate as 20.66%. Another 3 818 participants were diagnosed as having T2DM (8.15%) with standardized rate as 6.90%. The prevalence of T2DM increased in parallel with the increase of age (trend χ(2)=2 833.671, trend P<0.001). The prevalence of T2DM in the fatty liver group was significantly higher than that in the non-fatty liver group, both in men or women and in the overall population. Compared with the group of non-fatty liver, the risks of T2DM in fatty liver group were seen 1.78 times higher in males, 2.33 times in women and 2.10 times in the overall population, after adjustment for factors as age, levels of education, smoking, drinking, physical exercise, BMI, family history of diabetes and some metabolic indicators (pressure, TC, TG, uric acid, ALT, AST, gamma-glutamyl transferase). Date from the interaction model showed that fatty liver and family history of diabetes present a positive additive interaction on T2DM (RERI=1.18, 95%CI: 0.59-1.78; AP=0.24, 95%CI: 0.14-0.34; S=1.43, 95%CI: 1.21-1.69). Conclusions: Fatty liver could significantly increase the risk of T2DM and a positive additive interaction was also observed between fatty liver and family history of diabetes on T2DM. It was important to strengthen the prevention program on T2DM, in order to effectively control the development of fatty liver.

OBJECTIVETo detect the expression of SCUBE3 in human osteosarcoma cell lines and surgical specimens of osteosarcomas and investigate its association with the patients' prognosis.

METHODSThe expression of SCUBE3 protein was detected in 5 osteosarcoma cell lines using Western blotting. CCK8 assay was used to assess the effect of SCUBE3 suppression mediated by two specific small interfering RNAs (siRNAs) on the proliferation of U2OS osteosarcoma cells, and the cell cycle changes were detected using flow cytometry. Immunohistochemistry was performed to detect the expression of SCUBE3 in 60 osteosarcoma tissues, and Kaplan-Meier method was performed for survival analysis of the patients.

RESULTSCompared with osteoblast hFOB1.19 cells, the osteosarcoma cell lines all showed significantly higher expressions of SCUBE3. In U2OS cells, suppression of SCUBE3 expression by siRNA significantly inhibited the cell proliferation (P<0.05). Kaplan-Meier survival analysis indicated that patients with high SCUBE3 expression had worse prognosis than those with low SCUBE3 expression (P=0.036).

CONCLUSIONSCUBE3 is up-regulated in the 5 osteosarcoma cell lines and in primary osteosarcoma tissues to promote the proliferation of osteosarcoma cells. A high SCUBE3 expression in osteosarcoma tissues is associated with a poor prognosis of the patients, suggesting that SCUBE3 can serve as a potential therapeutic target for osteosarcoma.

OBJECTIVETo detect the expression of CXCL14 in human osteosarcoma cell lines and tissues and investigate its association with the prognosis of the patients.

METHODSRT-PCR, enzyme-linked immunosorbent assay (ELISA) and real-time PCR were used to detect the expression of CXCL14 in 4 osteosarcoma cell lines and in 40 pairs of osteosarcoma tissues and adjacent muscular tissues. CCK8 assay and colony formation assay was used to assess the effect of CXCL14 suppression mediated by two specific siRNAs on the proliferation of U2OS osteosarcoma cells. Immunohistochemistry was performed to detect the expression of CXCL14 in 58 osteosarcoma tissues, and Kaplan-Meier method and log-rank test were performed for survival analysis of the patients.

RESULTSSignificant up-regulation of CXCL14 expression was found in the osteosarcoma cell lines and in osteosarcoma tissues compared with the adjacent muscles (P<0.01). In U2OS cell, suppression of CXCL14 expression by siRNA significantly inhibited the cell proliferation (P<0.01) and colony formation rate (P<0.05). Kaplan-Meier survival analysis indicated that patients with high CXCL14 expression had worse prognosis than those with low CXCL14 expression (P=0.02).

CONCLUSIONCXCL14 is up-regulated in both osteosarcoma cell lines and primary osteosarcoma tissues to promote the proliferation of osteosarcoma cells. A high CXCL14 expression in osteosarcoma tissues is associated with a poor prognosis, suggesting the that CXCL14 serve as a potential therapeutic target for osteosarcoma.
