		                        			ObjectiveTo investigate the effect of Dendrobium officinale polysaccharide (DOP)on CCl4-induced hepatic fibrosis(HF)and its mechanism. MethodsA total of 56 male SD rats were randomly divided into seven groups: normal group(NG),model group(MG),colchicine group(CG, 0.1 mg/kg), Fuzheng Huayu group(FG, 0.45 g/kg),low-dose DOP group(LDG, 0.05 g/kg),middle-dose DOP group(MDG, 0.1 g/kg)and high-dose DOP group(HDG,0.2 g/kg),with 8 rats in each group. HF rat model was established by subcutaneous injection with 40% CCl4 olive oil mixture, every 3-day for 10 weeks. At the end of the sixth week, the drug groups were treated with colchicine, Fuzheng Huayu and DOP solution by gavage respectively, once a day for 4 weeks. NG and MG groups were similarly handled with an equal amount of 0.9 % normal saline. Liver histopathology was detected using hematoxylin-eosin (HE), Masson and Sirius red staining; blood biochemistry was tested for liver function and four indicators of HF; RT-qPCR and Western Blot were used to measure the expression of α-SMA, Col-I, E-cadherin, and ZEB1 genes and proteins in the liver tissues of rats, respectively. ResultsHE, Masson, and Sirius red staining showed that the liver tissue of MG rats had typical pathologic features of HF, and the degree of HF was alleviated in LDG, MDG, and HDG rats, respectively. Liver function test results showed that the serum AST, TBIL, and AKP levels were significantly lower in LDG, MDG, and HDG, compared with those of the MG (P < 0.05 or < 0.01). Meanwhile, ALT levels in serum deceased remarkably except in LDG (P < 0.05 or < 0.01). The four results of HF showed that the serum HA, LN, PC-Ⅲ, and COL-Ⅳ levels in LDG, MDG, and HDG rats were significantly decreased compared with those of the MG (P < 0.05 or < 0.01). The relative expressions of α-SMA, COL-I, and ZEB1 genes and proteins were significantly decreased in the liver tissues of LDG, MDG, and HDG (P < 0.05 or < 0.01), and the relative expression of E-cadherin gene and protein increased (P < 0.05 or < 0.01). In addition, the expressions of HA, α-SMA, COL-I, ZEB1 and E-cadherin were dependent on the dose of DOP. ConclusionDOP alleviated the degree of CCl4 induced HF in rats by inhibiting the epithelial-mesenchymal transition in liver tissue.

		                        			ObjectiveTo investigate the effect of Dendrobium officinale polysaccharides (DOP) in reversing carbon tetrachloride (CCl4)-induced hepatic fibrosis (HF) in rats via the Notch signaling pathway and evaluate the therapeutic effect of DOP by ultrasound elastography. MethodFifty-six male SD rats were randomized into normal, model, colchicine (1×10-4 g·kg-1), Fuzheng Huayu powder (0.45 g·kg-1), and low-, medium-, and high-dose (0.05, 0.1, 0.2 g·kg-1) DOP groups (n=8). The rats in the model group and each treatment group were injected subcutaneously with a mixture of CCl4-olive oil (2∶3) once every 3 days for 10 weeks. After 6 weeks of modelling, the rats were administrated with corresponding drugs once a day for 4 weeks. Hematoxylin-eosin (HE) staining and Masson staining were employed to observe the pathomorphological changes of the liver tissue. An automatic biochemical analyzer was used to measure the serum levels of alanine aminotransferase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and total bile acids (TBA). Enzyme-linked immunosorbent assay (ELISA) was employed to measure the serum levels of hyaluronic acid (HA), laminin (LN), type Ⅲ precollagen (PC-Ⅲ), and type Ⅳ collagen (Col-Ⅳ). The mRNA and protein levels of α-smooth muscle actin (α-SMA), Notch1, Jagged1, and Hes1 in the liver tissue were determined by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot, respectively. The Young's modulus (YM) of the rat liver was measured by acoustic radiation force impulse (ARFI) elastography before and after treatment. Then, the correlations of YM with the serum levels of HA, LN, PC-Ⅲ, and Col-Ⅳ and the protein levels of α-SMA and Notch1 signaling pathway-related factors in the liver tissue were analyzed. ResultCompared with the normal group, the model group showed disordered arrangement of liver cell cords, obvious infiltration of inflammatory cells, appearance of a large number of fat vacuoles, and fibrous proliferation, elevated levels of ALT, AST, TBA, ALP, HA, LN, PC-Ⅲ, and Col-Ⅳ in the serum, and up-regulated mRNA and protein levels of α-SMA, Notch1, Jagged1, and Hes1 in the liver tissue (P<0.01). Compared with the model group, drug interventions alleviated the pseudolobule formation and the collagen deposition in confluent areas. Except that the serum level of ALT in the low-dose DOP group had no significant changes, drug interventions, especially high-dose DOP, lowered the levels of ALT, AST, TBA, ALP, HA, LN, PC-Ⅲ, and Col-Ⅳ in the serum and down-regulated the mRNA and protein levels of α-SMA, Notch1, Jagged1, and Hes1 in the liver tissue (P<0.05, P<0.01). The results of ARFI and correlation analysis showed that the YM of the liver tissue was increased in the model group (P<0.01) compared with that in the normal group, Compared with the model group, drug interventions decreased YM (P<0.01). YM was positively correlated with the expression levels of HA, LN, PC-Ⅲ, α-SMA, Notch1, Jagged1, and Hes1s (r=0.754, 0.734, 0.801, 0.885, 0.896, 0.757, and 0.800, respectively, P<0.01), and it had a moderate correlation with Col-Ⅳ (r=0.688, P<0.01). ConclusionDOP can reverse HF by down-regulating the Notch1/Jagged1/Hes1 signaling pathway. YM can be used as an indicator in the assessment of the efficacy of DOP against HF.

		                        			Objective: Compare and analyze the results of the domestic Lanyi AH600 glycated hemoglobin analyzer and other different detection systems to understand the comparability of the detection results of different detectors, and establish the best cut point of Lanyi AH600 determination of haemoglobin A1c (HbA1c) in the diagnosis of diabetes. Methods: Multi center cohort study was adopted. The clinical laboratory departments of 18 medical institutions independently collected test samples from their respective hospitals from March to April 2022, and independently completed comparative analysis of the evaluated instrument (Lanyi AH600) and the reference instrument HbA1c. The reference instruments include four different brands of glycosylated hemoglobin meters, including Arkray, Bio-Rad, DOSOH, and Huizhong. Scatter plot was used to calculate the correlation between the results of different detection systems, and the regression equation was calculated. The consistency analysis between the results of different detection systems was evaluated by Bland Altman method. Consistency judgment principles: (1) When the 95% limits of agreement (95% LoA) of the measurement difference was within 0.4% HbA1c and the measurement score was≥80 points, the comparison consistency was good; (2) When the measurement difference of 95% LoA exceeded 0.4% HbA1c, and the measurement score was≥80 points, the comparison consistency was relatively good; (3) The measurement score was less than 80 points, the comparison consistency was poor. The difference between the results of different detection systems was tested by paired sample T test or Wilcoxon paired sign rank sum test; The best cut-off point of diabetes was analyzed by receiver operating characteristic curve (ROC). Results: The correlation coefficient R2 of results between Lanyi AH600 and the reference instrument in 16 hospitals is≥0.99; The Bland Altman consistency analysis showed that the difference of 95% LoA in Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180) was -0.486%-0.325%, and the measurement score was 94.6 points (473/500); The difference of 95% LoA in the Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant II) was -0.727%-0.612%, and the measurement score was 89.8 points; The difference of 95% LoA in the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT) was -0.231%-0.461%, and the measurement score was 96.6 points; The difference of 95% LoA in the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT) was -0.469%-0.479%, and the measurement score was 91.9 points. The other 14 hospitals, Lanyi AH600, were compared with 4 reference instrument brands, the difference of 95% LoA was less than 0.4% HbA1c, and the scores were all greater than 95 points. The results of paired sample T test or Wilcoxon paired sign rank sum test showed that there was no statistically significant difference between Lanyi AH600 and the reference instrument Arkray HA8180 (Z=1.665,P=0.096), with no statistical difference. The mean difference between the measured values of the two instruments was 0.004%. The comparison data of Lanyi AH600 and the reference instrument of all other institutions had significant differences (all P<0.001), however, it was necessary to consider whether it was within the clinical acceptable range in combination with the results of the Bland-Altman consistency analysis. The ROC curve of HbA1c detected by Lanyi AH600 in 985 patients with diabetes and 3 423 patients with non-diabetes was analyzed, the area under curve (AUC) was 0.877, the standard error was 0.007, and the 95% confidence interval 95%CI was (0.864, 0.891), which was statistically significant (P<0.001). The maximum value of Youden index was 0.634, and the corresponding HbA1c cut point was 6.235%. The sensitivity and specificity of diabetes diagnosis were 76.2% and 87.2%, respectively. Conclusion: Among the hospitals and instruments currently included in this study, among these four hospitals included Nanjing Maternity and Child Health Care Hospital in Jiangsu Province (reference instrument: Arkray HA8180), Tibetan Traditional Medical Hospital of TAR (reference instrument: Bio-Rad Variant Ⅱ), the People's Hospital of Chongqing Liang Jiang New Area (reference instrument: Huizhong MQ-2000PT), and the Taihe Hospital of traditional Chinese Medicine in Anhui Province (reference instrument: Huizhong MQ-2000PT), the comparison between Lanyi AH600 and the reference instruments showed relatively good consistency, while the other 14 hospitals involved four different brands of reference instruments: Arkray, Bio-Rad, DOSOH, and Huizhong, Lanyi AH600 had good consistency with its comparison. The best cut point of the domestic Lanyi AH600 for detecting HbA1c in the diagnosis of diabetes is 6.235%.

		                        			Objective: To investigate the safety, feasibility and short-term efficacy of total laparoscopic loop ileostomy reversal in patients after resection of rectal cancer. Methods: The clinical data of 20 patients who underwent total laparoscopic loop ileoscopic loop ileostomy after radical resection of rectal cancer at Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, or Beijing Chaoyang District Sanhuan Cancer Hospital from October 2019 to June 2020 were collected and retrospectively analyzed. Results: All patients had successfully underwent total laparoscopic ileostomy reversal without conversion to open surgery or discontinued operation. No perioperative related death cases were found. In the whole group, the median operation time was 97 (60-145) minutes and the median intraoperative blood loss was 20 (10-100) milliliters. The median Visual Analogue Scale (VAS) score was 1.9 (1-5) one day after the operation. Nobody needed to use additional analgesic drugs. The median time to grand activities was 25 (16-42) hours, the median time to flatus was 44 (19-51) hours, and the median hospitalization after operation was 6.9 (5-9) days. No patients underwent operation related complications such as operative incision infection, abdominal and pelvic infection, intestinal obstruction, anastomotic leakage, bleeding and so on. Conclusions: Total laparoscopic loop ileostomy reversal appears to be safe, feasible and with promising efficacy for selected patients.

		                        			 Background:
		                        			As the survival rate of cancer patients increases, the clinical importance of rehabilitation provided by healthcare professionals also increases. However, the evidence supporting the relevance of rehabilitation programs is insufficient. This study aimed to review the literature on effectiveness in physical function, quality of life (QOL) or fatigue of supervised physical rehabilitation in patients with advanced cancer. 
		                        		
		                        			Methods:
		                        			A systematic review and meta-analysis was conducted following the Cochrane guidelines. We narratively described the results when meta-analysis was not applicable or appropriate. Literature databases including Ovid-MEDLINE, Ovid-EMBASE, and the Cochrane Library, as well as several Korean domestic databases, were searched up to June 2017 for studies that investigated the effectiveness of supervised physical rehabilitation programs on physical function, QOL or fatigue in patients with advanced cancer. The quality of the selected studies was evaluated independently by paired reviewers. 
		                        		
		                        			Results:
		                        			Eleven studies with 922 participants were finally selected among 2,459 articles. The meta-analysis revealed that after physical exercise, the physical activity level and strength of patients with advanced cancer increased significantly. The QOL showed a statistically significant improvement after physical rehabilitation according to the European Organization for Research and Treatment of Cancer version C30. Though some of measurements about cardiovascular endurance or strength in several studies were not able to be synthesized, each study reported that they were significantly improved after receiving rehabilitation. 
		                        		
		                        			Conclusion
		                        			Supervised physical rehabilitation for patients with advanced cancer is effective in improving physical activity, strength, and QOL. However, more trials are needed to prove the effectiveness of supervised exercise and to strengthen the evidence.

		                        			Supercritical fluid chromatography (SFC) meets with great favor due to its high efficiency, low organic solvent consumption, and the specialty for the identification of the isomeric species. This review de-scribes the advances of SFC in targeted and untargeted lipid profiling. The advancement of the SFC in-struments and the stationary phases are summarized. Typical applications of SFC to the targeted and untargeted lipid profiling are discussed in detail. Moreover, the perspectives of SFC in the lipid profiling are also proposed. As a useful and promising tool for investigating lipids in vitro and in vivo, SFC will predictably obtain further development.

		                        			PURPOSE: Internal mammary lymph node (IMN) involvement is associated with poor prognosis in breast cancer. This study investigated the treatment outcomes of initial clinically IMN-positive breast cancer patients who received adjuvant radiotherapy (RT), including IMN irradiation, following primary breast surgery. MATERIALS AND METHODS: We retrospectively reviewed data of 95 breast cancer patients with clinically detected IMNs at diagnosis treated with surgery and RT between June 2009 and December 2015. Patients received adjuvant RT to the whole breast/chest wall and regional lymph node (axillary, internal mammary, and supraclavicular) areas. Twelve patients received an additional boost to the IMN area. RESULTS: The median follow-up was 43.2 months (range, 4.5 to 100.5 months). Among 77 patients who received neoadjuvant chemotherapy, 52 (67.5%) showed IMN normalization and 19 (24.6%) showed a partial response to IMN. There were 3 and 24 cases of IMN failure and any recurrence, respectively. The 5-year IMN failure-free survival, disease-free survival (DFS), and overall survival (OS) were 96%, 70%, and 84%, respectively. IMN failure-free survival was significantly affected by resection margin status (97.7% if negative, 87.5% for close or positive margins; p = 0.009). All three patients with IMN failure had initial IMN size ≥1 cm and did not receive IMN boost irradiation. The median age of the three patients was 31 years, and all had hormone receptor-negative tumors. CONCLUSION: RT provides excellent IMN control without the support of IMN surgery. Intensity-modulated radiotherapy, including IMN boost for breast cancer patients, is a safe and effective technique for regional lymph node irradiation.

		                        			BACKGROUND: Strategically improving health-related quality of life (HRQOL) should be discussed among overweight middle-aged women who are vulnerable to low HRQOL. We examined firstly if overweight middle-aged women would have significantly lower levels of HRQOL and health-promoting behaviors than normal-weight middle-aged women, and to examine secondly if health-promoting behaviors would be significantly associated with generic and obesity-specific HRQOLs within the overweight middle-aged women. METHODS: We conducted a cross-sectional, comparative study. Participants were 119 women aged 30–49 years who were recruited from a community in Seoul, South Korea; 63 women for the overweight group who were recruited from a baseline sample of the Community-Based Heart and Weight Management Trial, while 56 for the normal-weight group who were recruited separetely. Health Promoting Lifestyle Profile II (HPLP II), World Health Organization Quality of Life-brief version (WHOQOL-BREF) of a generic HRQOL measure, and Impact of Weight on Quality of Life-Lite (IWQOL-Lite) of an obesity-specific HRQOL measure were used. RESULTS: Compared to the normal-weight group, the overweight group showed significantly lower scores of total WHOQOL-BREF as well as some HPLP II subscales including stress management (P=0.029). Among the HPLP II subscales, stress management was significantly and positively associated with total WHOQOL-BREF (β=1.58, P=0.003) and self-esteem IWQOL-Lite (β=11.58, P=0.034) among the overweight group. CONCLUSIONS: Among middle-aged overweight women, low levels of health-promoting behavior for stress management were shown, which should be strategically increased for improving their generic and obesity-specific HRQOLs.

		                        			Patients who have a lower facial asymmetry with compensatory head posture (developmental facial asymmetry) may have minor temporomandibular (T-M) joint problems and tend to mask their asymmetry by tilting the head for camouflage of their chin deviation. However, this compensatory head posture can give the impression of orbital dystopia and c spine deviation. When these patients undergo bimaxillary orthognathic surgery, orbital canting and head tilting improves gradually without the need for camouflage, and bleary eyes become clearer. We evaluated 13 patients who underwent LeFort I osteotomy combined with bilateral sagittal split osteotomy of the mandible for developmental facial asymmetry to quantitatively observe whole facial postural changes after surgery. Pre-operative and post-operative 1:1 full-face photographs of the patients were analyzed to compare the degrees of head tilting and orbital canting and the sizes of the eye opening. After bimaxillary orthognathic surgery, eye canting decreased from 2.6° to 1.5°, eye and lip lines came closer to parallel, and the degree of head tilting decreased from 3.4° to 1.3°. The eyes also appeared to open wider. Correction of lower facial skeletal asymmetry through bimaxillary orthognathic surgery improved head tilting and orbital canting gradually by eliminating the need of compensatory head posture. Facial expressions also changed as the size of the eyes increased due to the reduction of facial muscle tension caused by T-M joint dysfunction.
