Yellowish sweating disease is one of the fluid-retention diseases recorded in Jin Gui Yao Lve(Synopsis of the Golden Cabinet).The symptoms of yellowish sweating disease are complex,involving multiple visceral lesions,which are caused by interior heat and exterior deficiency,together with the concurrent invasion of pathogens of wind and water.Huangqi Shaoyao Guizhi Kujiu Decoction(mainly composed of Astragali Radix,Paeoniae Radix Alba,Cinnamomi Ramulus and vinegar)and Guizhi Plus Huangqi Decoction(mainly composed of Cinnamomi Ramulus and Astragali Radix)are the classical formula for the treatment of yellowish sweating disease.Both of the formulas have the actions of warming defensive qi and dredging yang,removing fluid retention and resolving dampness.Usually suffering heat in the spleen and stomach,together with carelessness in daily living and wind-water pathogens attacking the exterior,contributes to the key pathogenesis of diabetes mellitus.The clinical manifestations,etiology,occurrence and progression,and prognosis of yellowish sweating disease are similar to those of diabetic complications.Therefore,the treatment of diabetes complications such as diabetic kidney disease,diabetic cardiomyopathy,diabetic peripheral neuropathy,diabetes mellitus complicated with liver dysfunction,diabetic foot,and diabetic retinopathy can follow the therapeutic principles of yellowish sweating disease,and can be achieved by the therapies of clearing heat and purging fire,dispelling cold and removing dampness,and nourishing nutritive yin and harmonizing defensive qi with the appropriate formulas.The exploration of the treatment of diabetes mellitus and its complications from the pathogenesis and symptom characteristics of yellowish sweating disease will expand the thoughts for treating diabetic complications with traditional Chinese medicine.

ObjectiveThis study aimed to analyze the difference in setup error before and after correction of systematic error. To determine the most appropriate image-guided strategy during HT treatment, we use different scanning ranges and image-guidance frequencies in patients with nasopharyngeal carcinoma (NPC) treated with helical tomotherapy (HT). MethodsFifteen patients with NPC who received HT treatment in Sun Yat-sen University Cancer Center from October 2019 to February 2020 were selected. Megavoltage computed tomography (MVCT) scanning was performed before each treatment. After five times of radiotherapy, system-error correction was performed to adjust the setup center. The setup errors before and after the correction of systematic errors, as well as the setup errors of different scanning ranges and different scanning frequencies, were collected for analysis and comparison. ResultsWhen comparing the setup errors before and after the correction of systematic error, the differences in setup errors in the left–right (LR), superior–inferior (SI), and anterior–posterior (AP) directions were statistically significant (P<0.05).The different scanning ranges of "nasopharynx + neck" and "nasopharynx" were compared, and a statistically significant difference was found in yaw rotational errors (P<0.05). In the comparison of daily and weekly scan frequency after system-error correction, a significant difference was found in AP direction (P<0.05). ConclusionDuring radiotherapy for NPC, the systematic error can be corrected according to the first five setup errors, and then small-scale scanning was selected for image-guided radiotherapy every day.

Objective: To evaluate the efficacy of supraclavicular fasciocutaneous island flap (SIF) for repairing the defect of parotid or auricle regions after tumor resection. Methods: From February 2019 to June 2021, 12 patients (11 males and 1 female, aged 54-77 years old), of whom 4 with parotid adenoid cystic carcinoma and 8 with auricular basal cell carcinoma underwent reconstruction surgery for postoperative defects in the parotid gland area and auricular area with SIF in the Department of Otorhinolaryngology Head and Neck Surgery, the Second Xiangya Hospital of Central South University and their clinical data were retrospectively analyzed. Size of the SIF, time for harvesting SIF, neck lymph node dissection and postoperative complications were recorded. Results: The flap areas were (6-9) cm × (8-13) cm, and the harvesting time for SIF ranged from 40 to 80 min, averaging 51.7 min. The donor sites were directly closed. All patients underwent ipsilateral levels Ⅰ-Ⅲ neck dissection, with 4 cases undergoing additional level Ⅳ neck dissection and 2 cases undergoing level Ⅳ-Ⅴ neck dissection. Of the 12 SIF, 10 were completely survival and 2 had flap arterial crisis with partial flap necrosis, in addition, 1 had donor site wound dehiscence. With follow-up of 10-42 months, there were no tumor recurrences in 10 patients, 1 patient was lost to follow-up at 10 months postoperatively, and 1 patient experienced local tumor recurrence at 11 months after surgery and died 15 months later. Conclusion: SIF is an easily harvested flap with good skin features matching the skin in parotid and auricle regions and less damage to donor site, and this flap has no need for microvascular anastomosis technique. SIF is feasible and effective for repairing defects in parotid and auricle area.

This study aims to investigate the expression, prognosis, and clinical significance of C5orf46 in gastric cancer and to study the interaction between the active components of C5orf46 and tarditional Chinese medicine. The ggplot2 package was utilized for differential expression analysis of C5orf46 in gastric cancer tissues and normal tissues. The survival package was used for survival analysis, univariate regression analysis, and multivariate regression analysis. Nomogram analysis was used to assess the connection between C5orf46 expression in gastric cancer and overall survival. The abundance of tumor-infiltrating lymphocytes was calculated by GSVA package. Coremine database, Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) database, and PubChem database were used to search the potential components corresponding to C5orf46 gene and tarditional Chinese medicine. Molecular docking was performed to explore the binding affinity of potential components to C5orf46. Cell experiments were performed to explore the expression of C5orf46 gene in cells of the blank group, model group, and drug administration groups. As compared with normal tissues, C5orf46 expression was higher in gastric cancer tissues, which had more significant predictive effects in the early stages(T2, N0, and M0). The more advanced the tumor node metastasis(TNM) stage, the higher the C5orf46 expression and the lower the probability of survival of patients with gastric cancer. The expression of C5orf46 positively correlated with the helper T cells1 in gastric cancer and the macrophage infiltration level in gastric cancer, and negatively correlated with B cells, central memory T cells, helper T cells 17, and follicular helper T cells. Seven potential components of C5orf46 were obtained, and three active components were obtained after the screening, which matched five tarditional Chinese medicines, namely, Sojae Semen Nigrum, Jujubae Fructus, Trichosanthis Fructus, Silybi Fructus, and Bambusae Concretio Silicea. Molecular docking revealed that sialic acid and adeno-sine monophosphate(AMP) had a good binding ability to C5orf46. The results of real-time quantitative polymerase chain reaction(RT-qPCR) and Western blot showed that, as compared with the model group, the mRNA and protein expression levels of C5orf46 were significantly lower in the drug administration groups. The lowest expression level was found at the concentration of 40 μmol·L~(-1). The results of this study provide ideas for the clinical development of traditional Chinese medicine compounds for the treatment of gastric cancer as well as other cancers.

Purpose:
Capecitabine is an extensively used oral prodrug of 5-fluorouracil in treatment of colon cancer and is known to cause hand-foot syndrome (HFS). As the target enzyme for capecitabine, thymidylate synthase (TYMS) plays a key role for 5-fluorouracil metabolism and has been associated with some side effects caused by capecitabine. The aim of our study is to identify the possible genetic predictors of capecitabine-induced HFS (CAP-HFS) in Chinese colorectal cancer patients.
Materials and Methods:
Whole exons of TYMS were sequenced for 288 extreme phenotype HFS patients, including 144 severe or early-onset (first 2 cycles) moderate HFS extreme cases and 144 extreme controls with no reported HFS. The associations between polymorphisms and CAP-HFS were analyzed using logistic regression under an additive model.
Results:
We identified a novel risk mutation (c.1A>G, chr18:657743), was associated with severe HFS in an extreme case who was affected during the first cycle of treatment. Moreover, we identified three new variants, rs3786362, rs699517, rs2790, and two previously reported variants, 5’VNTR 2R/3R and 3′-untranslated region 6-bp ins-del, which were significantly associated with CAP-HFS (p < 0.05). In silico analysis revealed that the effect of these polymorphisms in the TYMS region on the development of HFS might not be restricted solely to the regulation of TYMS expression, but also the TYMS catalytic activity through the indirect effect on ENOSF1 expression.
Conclusion
This study identified new polymorphisms in TYMS gene significantly associated with CAP-HFS, which may serve as useful genetic predictors for CAP-HFS and help to elucidate the underlying mechanism of HFS.

Objective To evaluate the methodological quality of clinical practice guidelines of rehabilitation using Appraisal of Guidelines for Research and Evaluation (AGREE) II.Methods Clinical practice guidelines of rehabilitation were searched in databases such as PubMed, EMBASE, Wanfang database, CNKI, China Biology Medicine disc and related websites from medlive.cn, National Institute for Health and Care Excellence, National Guideline Clearinghouse, Scottish Intercollegiate Guidelines Network, World Health Organization, and Guidelines International Network from establishment to January 11, 2020. Two researchers reviewed literatures and assessed the methodological quality of the guidelines independently by using AGREE II; any disagreements needed to be discussed in a consensus meeting.Results A total of 84 guidelines were included in the study, with 67 foreign guidelines and 17 domestic guidelines. The average score rate for all the guidelines was 48.1%, in which 49.9% for the foreign guidelines and 40.7% for the domestic guidelines. In the six areas of AGREE II, the average score rate of the foreign guidelines was higher than that of domestic ones (|Z| > 2.034, P < 0.05), expect applicability; the average score rate of clarity and independence improved with the launch of AGREE Ⅱ ( Z > 2.130, P < 0.05). The average scores rate ranged from high to low followed as range and purpose (41.6%), clarity (39.9%), participants (24.5%), rigor (23.2%), independence (15.5%) and applicability (12.9%). Conclusion Clinical practice guidelines of rehabilitation is mainly of low quality by AGREE II. Guideline developers need to work after AGREE Ⅱ standard in the future.

OBJECTIVE:
This study was conducted to investigate the regulation of endoplasmic reticulum stress on Nrf2 signaling pathway in the kidneys of rats.
METHODS:
Rats were divided into twelve groups of six animals each. Some groups were pre-administered with bacitracin or tauroursodeoxycholic acid (TUDCA), and all of them were treated with 5-20 μmol/kg cadmium (Cd) for 48 h. The oxidative stress levels were analyzed using kits. The mRNA and protein expression levels of endoplasmic reticulum stress-related factors and Nrf2 signaling pathway-related factors were determined using RT-PCR and western blot.
RESULTS:
Cd exposure resulted in oxidative stress in the kidneys of rats and upregulated the expression of endoplasmic reticulum stress (ERS)-related factors and Nrf2 signaling pathway-related factors, especially at doses of 10 and 20 μmol/kg Cd, and the expression changes were particularly obvious. Moreover, after pretreatment with bacitracin, Cd upregulated the expression of ERS-related factors to a certain extent and, at higher doses, increased the mRNA expression of Nrf2. After pretreatment with TUDCA, Cd reduced the level of ERS to a certain extent; however, at these doses, there were no significant changes in the expression of Nrf2.
CONCLUSION
Cadmium can result in ERS and oxidative stress in the kidneys of rats, activate Nrf2, and upregulate the transcriptional expression of phase II detoxification enzymes under these experimental conditions. ERS has a positive regulation effect on Nrf2 signaling pathway but has little effect on the negative regulation of Nrf2 signaling pathway in cadmium toxicity.

Objective:
To investigate the effects of melatonin on the oxidative stress and signaling pathways of apoptosis-related genes following testicular torsion/detorsion in male rats.
METHODS:
Twenty-four healthy male Sprague-Dawley rats were randomly divided into a control, a torsion and a melatonin group of equal number. The torsion model was made in the animals of the latter two groups by 720° torsion of the left testis for 2 hours. The rats of the torsion and melatonin groups received intraperitoneal injection of isotonic saline and melatonin (17 mg/kg) respectively at 15 minutes prior to detorsion. At 24 hours after modeling, testis tissues were collected from the rats for detection of the apoptosis of the germ cells by flow cytometry (FCM), analysis of the expressions of Fas, Fas ligand (FasL) and Bax mRNA by quantitative real-time PCR (qRT-PCR), measurement of the cytochrome C content released from the mitochondrion by Western blot, and determination of the total antioxidant capacity (T-AOC) and the levels of myeloperoxidase (MPO) and malodialdehyde (MDA) by spectrophotometry.
RESULTS:
Compared with the torsion group, the rats treated with melatonin showed significantly increased normal testicular cells ([77.81 ± 6.52]% vs [88.61 ± 7.93]%, P < 0.05), decreased early apoptotic germ cells ([16.74 ± 3.16]% vs [6.97 ± 1.65]%, P < 0.05), down-regulated expressions of Fas ([4.52 ± 0.29] vs [2.66 ± 0.37], P < 0.01), FasL ([2.82 ± 0.30] vs [1.73 ± 0.18], P < 0.01) and Bax mRNA ([2.39 ± 0.18] vs [1.50 ± 0.14], P < 0.01), reduced levels of cytochrome C ([1.40 ± 0.38] vs [0.67 ± 0.30], P < 0.01), MPO ([0.52 ± 0.15] vs [0.19 ± 0.10] U/g prot, P < 0.01) and MDA [6.37 ± 1.73] vs [3.98 ± 0.90] nmol/mg prot, P < 0.01) and elevated T-AOC ([0.76 ± 0.25] vs [1.55 ± 0.32] U/mg prot, P < 0.01).
CONCLUSIONS
Melatonin has a significant protective effect on spermatogenesis after testicular torsion by regulating the expressions of apoptosis-related genes and increasing T-AOC in the testis tissue.
