Objective To investigate the clinical efficacy of Xuanfei Yipi Formula,a prescription derived from modified Jianpi Pill recorded in Yi Fang Ji Jie(A Collection of Prescriptions with Expositions),in treating senile sarcopenia with spleen-stomach weakness type,and to observe its effect on chronic low-grade inflammation of the patients.Methods Seventy cases of senile sarcopenia patients of spleen-stomach weakness type were randomly divided into an observation group and a control group,with 35 cases in each group.The control group was given exercise and nutritional guidance,while the observation group was treated with Xuanfei Yipi Formula orally on the basis of the control group,and the intervention time of both groups was eight weeks.The changes of traditional Chinese medicine(TCM)syndrome scores,appendicular skeletal muscle mass index(ASMI),grip strength,6-meter walking pace,and the serum levels of C-reactive protein(CRP),interleukin 6(IL-6),tumor necrosis factor α(TNF-α)in the two groups before and after treatment were observed.After treatment,the clinical efficacy and safety of the patients in the two groups were evaluated.Results(1)After eight weeks of treatment,the total effective rate in the observation group was 94.29%(33/35),and that in the control group was 77.14%(27/35),the intergroup comparison(by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the TCM syndrome scores in the two groups were significantly lower than those before treatment(P＜0.05),and the decrease of TCM syndrome score in the observation group was more obviously than that in the control group(P＜0.01).(3)After eight weeks of treatment,the ASMI,grip strength and 6-meter walking pace in the two groups were significantly higher than those before treatment,and the increase of ASMI and grip strength in the observation group was more obviously than that in the control group(P＜0.05).(4)After eight weeks of treatment,the levels of serum CRP,IL-6,and TNF-α in the two groups were decreased significantly compared with those before treatment(P＜0.05),and the decrease of serum CRP level in the observation group was more obviously than that in the control group(P＜0.05).(5)During the treatment,no obvious adverse reactions occurred in both groups,and the safety indexes of liver and kidney functions of the patients were all within the normal range.Conclusion Xuanfei Yipi Formula can improve the clinical symptoms of senile sarcopenia patients,and its mechanism is probably related with the regulation of chronic low-grade inflammation.

The third-generation epidermal growth factor receptor (EGFR) inhibitor osimertinib (OSI) has been approved as the first-line treatment for EGFR-mutant non-small cell lung cancer (NSCLC). This study aims to explore a rational combination strategy for enhancing the OSI efficacy. In this study, OSI induced higher CD47 expression, an important anti-phagocytic immune checkpoint, via the NF-κB pathway in EGFR-mutant NSCLC HCC827 and NCI-H1975 cells. The combination treatment of OSI and the anti-CD47 antibody exhibited dramatically increasing phagocytosis in HCC827 and NCI-H1975 cells, which highly relied on the antibody-dependent cellular phagocytosis effect. Consistently, the enhanced phagocytosis index from combination treatment was reversed in CD47 knockout HCC827 cells. Meanwhile, combining the anti-CD47 antibody significantly augmented the anticancer effect of OSI in HCC827 xenograft mice model. Notably, OSI induced the surface exposure of "eat me" signal calreticulin and reduced the expression of immune-inhibitory receptor PD-L1 in cancer cells, which might contribute to the increased phagocytosis on cancer cells pretreated with OSI. In summary, these findings suggest the multidimensional regulation by OSI and encourage the further exploration of combining anti-CD47 antibody with OSI as a new strategy to enhance the anticancer efficacy in EGFR-mutant NSCLC with CD47 activation induced by OSI.

Described as a "don't eat me" signal, CD47 becomes a vital immune checkpoint in cancer. Its interaction with signal regulatory protein alpha (SIRPα) prevents macrophage phagocytosis. In recent years, a growing body of evidences have unveiled that CD47-based combination therapy exhibits a superior anti-cancer effect. Latest clinical trials about CD47 have adopted the regimen of collaborating with other therapies or developing CD47-directed bispecific antibodies, indicating the combination strategy as a general trend of the future. In this review, clinical and preclinical cases about the current combination strategies targeting CD47 are collected, their underlying mechanisms of action are discussed, and ideas from future perspectives are shared.

Diabetic nephropathy(DN) is a kind of severe diabetes mellitus(DM) complications,which is one of the most common cause of end-stage renal failure.The incidence of DN increases with the increase of the number of DM patients,and early prevention is the key.DM and DN are characteristic advantages of Tibetan medicine,the "holistic view" of dynamic balance based on the three major factors in the body(Sanyin,included rlung,mkhris-pa and bad-gan) is a unique understanding of DM and DN among Tibetan medical practitioners,and which has rich and unique clinical and medication experiences in DN treatment.This paper discussed the medical theory "holistic view" on the Tibetan medicine for DM and DN,dug commonly used Tibetan drugs and Tibetan medical prescriptions for clinical treatment of DN,in order to provide new ideas for the treatment of DN and the discovery of new drugs for DN, and give full play to the unique advantages of Tibetan medicine.

Objective To explore the correlation among farnesoid X receptor (FXR), clinical stage and survival time of patients with pancreatic cancer. Methods The total protein and mRNA were extracted from cultured 8 pan-creatic cancer cell lines,and the expression level of FXR in pancreatic cancer cells was detected by Western bolt and real-time PCR. We collected 5 cases of normal pancreatic tissue and 50 cases of pancreatic cancer tissues,and used immunohistochemistry method to detect FRX expression in normal pancreatic tissue and pancreatic cancer. Ac-cording to the different expression level of FXR,these 50 patients were divided into low expression group and high expression group, the correlation of clinical data and FRX expression level was analyzed. Furthermore, Kaplan-Meier and log-rank analysis of prognostic factors was assessed in a multivariable analysis using a Cox proportional hazards model. Results FXR was differently expressed in 8 pancreatic cancer cell lines and pancreatic cancer tis-sues. FXR was closely related to the pathological G stage of pancreatic cancer(P＜0.05). FXR and pathological G stage were significantly correlated with the patients' survival time. The survival time of the patients with high FXR expression was significantly longer than that of patients with low FXR expression (P＜0.05). Conclusions The expression of FXR is closely related to the pathological G stage in patients with pancreatic cancer. Both FXR expression and pathological G stage are independent prognostic factors in patients with pancreatic cancer.

Objective To explore the survival time and its influencing factors of patients in Guizhou Province after they received antiretroviral therapy(ART)for treating human immunodeficiency virus (HIV)infection and acquired immunodeficiency syndrome (AIDS).Methods A retrospective cohort analysis was conducted to analyze survival time of AIDS patients who received ART in Guizhou Province in 2005-2016,life table method was used to calculate the survival probability,Cox proportional hazards regression model was used to analyze the influencing factors of survival time.Results A total of 15921 patients were included in the study,the median age at the beginning of therapy was(42.13±14.40)years old,58.61% of patients were married/housemate.The length of ART follow-up was (median[P 25 -P 75 ]:15.96[6.00 - 33.00])months.9.77% of the follow-up cases died,59.29% of the deaths occurred within 12 months of initiation of treatment;survival rates in the first,fifth,and tenth year were 93.00%,82.00%,and 74.00% respectively.Cox proportional hazards regression model analysis showed that fe-male patients were 0.58 times more likely to die than male patients(95% CI :0.49-0.68);the risk of death in-creased with increase of ages;the higher the baseline CD4+ T lymphocyte count,the lower the risk of death;the risk of death in patients without symptoms or signs before therapy was 0.70 times than those with symptoms or signs(95% CI :0.60-0.81).Conclusion The antiviral therapy of AIDS patients in Guizhou Province is generally well,patients with high risk factors for death should be paid high attention,it is suggested that medical level and service quality should be improved when patients are treated.

OBJECTIVETo investigate the clinical effect of fast-track surgery combined with Chinese medicine treatment in devascularization operation for cirrhotic esophageal varices.

METHODSSeventy-two patients with cirrhotic esophageal varices were selected from January 2009 to June 2013, and randomly assigned to a conventional group and a fast-track group (fast-track surgery combined with Chinese medicine treatment) using a randomized digital table, 36 cases in each group. Operation and anesthesia recovery time, postoperative hospitalization and quality of life were recorded and compared between groups during the perioperative period.

RESULTSCompared with the conventional group, the fast-track group had longer operation time (253.6±46.4 min vs. 220.6±51.0 min) and anesthesia recovery time (50.5±15.9 min vs. 23.5±9.6 min; P<0.01); less bleeding (311.3±46.8 mL vs. 356.2±57.5 mL; P<0.01) and less transfusion (1932.3±106.9 mL vs. 2045.6±115.4 mL; P<0.01); as well as faster recovery of gastrointestinal function, shorter postoperative hospitalization and higher quality of life. There were no serious postoperative complications and no further bleeding occurred.

CONCLUSIONFast-track surgery combined with Chinese medicine treatment is a safe and feasible approach to accelerate the recovery of patients with cirrhotic portal hypertension in perioperative period of devascularization operation.

OBJECTIVEThe aim of this study was to investigate the association between urinary cadmium and clinicopathological characteristics of breast cancer.

METHODSThe clinicopathological characteristics of 240 patients with breast cancer were obtained and urine specimens were collected from October 2009 to July 2010. The concentration of urinary cadmium was determined by inductively coupled plasma mass spectrometry (ICP-MS). χ(2) test and Wilcoxon rank sum test were used to analyze whether urinary cadmium is associated with clinicopathological characteristics of breast cancer.

RESULTSThe median concentration of urine cadmium of 240 patients was 1.99 µg/g (25th percentile, 1.32 µg/g; 75th percentile, 2.88 µg/g). HER-2 positive rate, regional/distant metastasis rate, and advanced stage rate in patients with the highest tertile of cadmium concentration were significantly higher than those in the patients with second and lowest Cd tertiles (P = 0.042, P = 0.028 and P = 0.017, respectively), and 28.2% vs. 16.5% for HER-2 and 47.2% vs. 32.0% for regional/distant metastasis, respectively. There were still significant associations between urinary cadmium levels and these clinicopathological parameters after being adjusted in age by unconditional logistic regression model, respectively (P < 0.05).

CONCLUSIONSThe results of this study suggest that urinary cadmium levels are associated with the HER-2 status, regional/distant metastasis status and stages of breast cancer, respectively. Cadmium may induce highly aggressive breast cancer in humans.

OBJECTIVETo describe the temporal trends in the mortality rate of gastric cancer during the period of 1988 and 2010, and to predict the gastric cancer mortality between 2016 - 2020.

METHODSThe data of gastric cancer mortality in Linzhou city between 1988 and 2010 was extracted from the cancer registry, including a total of 11 714 cases, covering 22 447 073 person-years. The mortality rate of gastric cancer of each 5-year period was calculated by sub-site and gender. Age-standardized rate (ASR) was calculated using the Chinese standard population in 1982. Intrinsic estimator (IE) model was used to fit the mortality trend by sub-site and gender, and to predict the mortality of gastric cancer in Linzhou city between 2016 and 2020.

RESULTSFrom 1988 to 2010, the gastric cancer mortality in Linzhou city was 52.18/100 000 (11 714/22 447 073) with the ASR at 49.23/100 000; the mortality in male was 67.02/100 000 (7678/11 455 512) with ASR at 68.68/100 000 while the mortality in female was 36.72/100 000 (4036/10 991 561) with ASR at 32.12/100 000. The mortality of cardia carcinoma was 27.87/100 000 (6257/22 447 073) with the ASR at 26.37/100 000; while the mortality of non-cardia carcinoma was 24.31/100 000 (5457/22 447 073) with the ASR at 22.86/100 000. The ASR of gastric cancer during 1988 - 1990 was 63.37/100 000 (1653 cases) and decreased by 28.34%, to 45.41/100 000 (2622 cases) during 2006 - 2010. The IE model showed that the birth cohort effect decreased greatly. The mortality risk of cardia carcinoma in population born after 1950s, decreased significantly; and the mortality risk of non-cardia carcinoma in population born in 20 century continually decreased. The death of gastric cancer among the population over 30 years old was predicted to be 3626 cases, increasing by 40.60% compared with the number between 2006 and 2010 (2579 cases). Among them, the mortality of cardia carcinoma increased by 51.89% (predicted number between 2016 and 2020 was 2456 cases, and 1617 cases between 2006 and 2010), and the mortality of non-cardia carcinoma increased by 21.62% (predicted number between 2016 and 2020 was 1170 cases, and 962 cases between 2006 and 2010).

CONCLUSIONThe mortality rate of gastric cancer in Linzhou city showed a decreasing trend during the period of 1988-2010, being mainly attributed to the cohort effect. However, the mortality will still increase in the future, between 2016 and 2020.

Chronic inflammation is thought to be the leading cause of colorectal cancer, and interleukin-10 (IL10) has been identified as a potent immunomodulatory cytokine that regulates inflammatory responses in the gastrointestinal tract. Although several single nucleotide polymorphisms (SNPs) in IL10 have been associated with the risk of colorectal cancer, their prognostic significance has not been determined. Two hundred and eighty-two colorectal cancer patients were genotyped for two candidate cancer-associated SNPs in IL10. The associations of these SNPs with distant metastasis-free survival and overall survival were evaluated by Kaplan-Meier analysis and Cox regression model. The minor homozygote GG genotype of IL10 rs3021094 was significantly associated with a 3.30-fold higher risk of death compared with the TT+TG genotypes (P=0.011). The patients with IL10 rs3021094 GG genotype also had a poorer overall survival in Kaplan-Meier analysis (log-rank P=0.007) and in multivariate Cox regression model (P=0.044) adjusting for age, gender, carcinoembryonic antigen levels, tumor differentiation, stage, lymphovascular invasion, and perineural invasion. In conclusion, our results suggest that IL10 rs3021094 might be a valuable prognostic biomarker for colorectal cancer patients.
