Objective:To explore influencing factors of the self-reported brief life quality satisfaction score(Brief-QoL) in patients with acromegaly and understand the persistent low Brief-QoL scores in cases achieving biochemical remission.Methods:This study included 836 acromegaly patients who were hospitalized at Peking Union Medical College Hospital between January 2012 and December 2020. We retrospectively examined how clinical characteristics, biochemical parameters, comorbidities, and symptoms influenced Brief-QoL. Among patients who achieved biochemical remission, differences in clinical symptoms and comorbidities were analyzed between the high and low quality of life groups.Results:Patients with well-controlled biochemical indicators at the last follow-up had generally high Brief-QoL. However, patients with symptoms such as headaches (47.8% in the low-score group vs 14.9% in the high-score group, P<0.001) and joint pain (69.6% in the low-score group vs 19.0% in the high-score group, P<0.001) had low Brief-QoL despite biochemical remission. Receiving combined treatment(52.4% in the low-score group vs 27.5% in the high-score group, P=0.030) and having comorbid diabetes or hyperlipidemia were significant factors leading to decreased quality of life. Conclusion:Brief-QoL is suitable for follow-up of outpatient patients. Early identification of factors affecting quality of life and timely intervention can facilitate the realization of standardized management.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

BACKGROUND: Management of gastric leak after sleeve gastrectomy (SG) is challenging due to its unpredictable outcomes. We aimed to summarize the characteristics of SG leaks and analyze interventions and corresponding outcomes in a real-world setting. METHODS: To retrospectively review of 15,721 SG procedures from 2010 to 2020 based on a national registry. A cumulative sum analysis was used to identify a fitting curve of gastric leak rate. The Kaplan-Meier method and log-rank tests were performed to calculate and compare the probabilities of relevant outcomes. The logistic regression analysis was conducted to determine the predictors of acute leaks. RESULTS: A total of 78 cases of SG leaks were collected with an incidence of 0.5% (78/15,721) from this registry (6 patients who had the primary SG in non-participating centers). After accumulating 260 cases in a bariatric surgery center, the leak rate decreased to a stably low value of under 1.17%. The significant differences presented in sex, waist circumference, and the proportion of hypoproteinemia and type 2 diabetes at baseline between patients with SG leak and the whole registry population ( P = 0.005, = 0.026, <0.001, and = 0.001, respectively). Moreover, 83.1% (59/71) of the leakage was near the esophagogastric junction region. Leakage healed in 64 (88.9%, 64/72) patients. The median healing time of acute and non-acute leaks was 5.93 months and 8.12 months, respectively. Acute leak (38/72, 52.8%) was the predominant type with a cumulative reoperation rate >50%, whereas the cumulative healing probability in the patients who required surgical treatment was significantly lower than those requring non-surgical treatment ( P = 0.013). Precise dissection in the His angle area was independently associated with a lower acute leak rate, whereas preservation ≥2 cm distance from the His angle area was an independent risk factor. CONCLUSIONS Male sex, elevated waist circumference, hypoproteinaemia, and type 2 diabetes are risk factors of gastric leaks after SG. Optimizing surgical techniques, including precise dissection of His angle area and preservation of smaller gastric fundus, should be suggested to prevent acute leaks.

Objective To establish and validate the nomogram prediction model of degenerative lumbar disc disease in young and middle-aged people.Methods From January 2020 to March 2022,232 young and middle-aged people who were examined with MRI of lumbar intervertebral disc and standard standing position lumbar anteroposterior and lateral X-ray films in Suzhou Ninth Hospital Affiliated to Soochow University were selected as the study subjects.Collecting the factors that may affect the occurrence of degenerative lumbar disc disease in young and middle-aged people,the people were divided into degenerative disease group(n=78)and non-degenerative disease group(n=154)according to the presence or absence of degenerative lumbar disc disease.Influencing factors were compared between the two groups,the independent influencing factors screened out by multifactor logistic regression,the nomograph model was constructed by R software,and the model verified.Results Among 232 young and middle-aged people included in this study,78(33.6%)had degenerative lumbar disc diseases.The results of multivariate logistic regression analysis showed that the increase of BMI,sedentariness,the increase of IL-1β level were the risk factors of degenerative lumbar disc disease in young and middle-aged people;the increase of pelvic incidence angle and the increase of miRNA-142-3p level were protective factors for degenerative lumbar disc disease in young and middle-aged people(P<0.05).The nomogram model was constructed according to the results of multifactor analysis.ROC results showed that AUC was 0.889(95%CI 0.844-0.933,P<0.05),the average absolute error of internal validation was 0.017,the prediction curve was basically fitted with the standard curve,and the H-L goodness of fit test showed that the model was consistent(P>0.05).The decision curve shows that the clinical benefit rate is the highest when the model prediction probability threshold is 0.16-0.80.Conclusions Degenerative lumbar disc disease in young and middle-aged people is affected by such factors as BMI,sedentariness,and incidence angle of pelvis,and the nomogram model established based on this has high differentiation and accuracy of prediction.

Objectives: To summarize the clinical phenotypes and the variation spectrum of ATP7B gene in Chinese children with Wilson's disease (WD) and to investigate their significance for early diagnosis. Methods: Retrospective analysis was performed on the clinical data of 316 children diagnosed as WD in Guangzhou Women and Children's Medical Center during the period from January 2010 to June 2021. The general situations, clinical manifestations, lab test results, imaging examinations, and ATP7B gene variant characteristics were collected. The patients were divided into asymptomatic WD group and symptomatic WD group based on the presence or absence of clinical symptoms at the time that WD diagnosis was made. The χ² test, t test or Mann-Whitney U test were used to compare the differences between groups. Results: Among the 316 children with WD, 199 were males and 117 were females, with the age of 5.4 (4.0, 7.6) years at diagnosis; 261 cases (82.6%) were asymptomatic with the age of 4.9 (3.9, 6.4) years; whereas 55 cases (17.4%) were symptomatic with the age of 9.6 (7.3, 12.0) years. The main symptoms invloved liver, kidney, nervous system, or skin damage. Of all the patients, 95.9% (303/316) had abnormal liver function at diagnosis; 98.1% (310/316) had the serum ceruloplasmin lever lower than 200 mg/L; 97.7% (302/309) had 24-hour urine copper content exceeding 40 μg; only 7.4% (23/310) had positive corneal K-F rings, 8.2% (23/281) had abnormal MRI signals in the lenticular nucleus, and all of them had symptoms of damage in liver, kidney or nervous system. Compared with the group of symptomatic WD, asymptomatic group had higher levels of serum alanine aminotransferase and lower levels ceruloplasmin and 24-hour urine copper [(208±137) vs. (72±78) U/L, (55±47) vs. (69±48) mg/L, 103 (72, 153) vs. 492 (230, 1 432) μg; t=9.98, -1.98, Z=-4.89, all P<0.001]. Among the 314 patients completing genetic sequencing, a total of 107 mutations in ATP7B gene were detected, of which 10 are novel variants, and 3 cases (1.0%) had large heterozygous deletion (exons 10 to exon 11) in ATP7B gene. The percentage of missense mutation in asymptomatic WD children was significantly higher than that in symptomatic WD (81.5% (422/518) vs. 69.1% (76/110), χ²=8.47, P<0.05). WD patients carrying homozygous variant of c.2 333G>T had significantly low levels of ceruloplasmin than those not carrying this variant ((23±5) vs. (61±48) mg/L, t=-2.34, P<0.001). Conclusions: The elevation of serum ALT is an important clue for early diagnosis of WD in children, while serum ceruloplasmin and 24-hour urine copper content are specific markers for early diagnosis of WD. In order to confirm the diagnosis of WD, it is necessary to combine the Sanger sequencing with multiplex ligation-dependent probe amplification or other testing technologies.

Colorectal cancer (CRC) is a common malignancy burdening people globally, with increasing morbidity and mortality nowadays, due to the alternation in the diet type and lifestyle in modern society. Berberine, a type of benzylisoquinoline alkaloid, is widely present in numerous medicinal plants, particularly including Coptidis Rhizoma. Mounting evidence reveals that berberine possesses an array of pharmacological effects, such as anti-inflammation, anti-bacterium, anti-cancer, anti-diabetes mellitus and so on. In particular, berberine exhibits substantial inhibition on various types of cancers including CRC. Hereby, we sought to systematically review the suppressive effect of berberine on CRC through the diminishment of the proliferation and metastasis, induction of apoptosis, arrest of cell cycle, regulation of inflammatory reaction, the reverse of chemotherapeutic resistance and restoration of gut microbiota in CRC, so as to shed light on the in-depth mechanisms underlying the treatment of CRC with berberine in the clinical setting.

To prove that ursolic acid(UA)could activate the autophagy of colorectal cancer HCT116 cells by inhibiting hedgehog signaling pathway. The effect of UA on the viability of HCT116 cells was determined by MTT assay. The effect of UA on the proliferation and migration of HCT116 cells was detected by crystal violet staining and scratch test. In the study on autophagy, the time points were screened out first: the autophagy fluorescence intensity of UA acting on HCT116 at different time points were detected by Cell Meter~(TM) Autophagy Assay Kit; Western blot was used to detect the expression of autophagy protein P62 at different time points. Then, Cell Meter~(TM) Autophagy Assay Kit was used to detect the effect of UA on autophagy fluorescence intensity of HCT116 cells. The effect of different doses of UA on the expressions of LC3Ⅱ and P62 proteins in HCT116 cells were detected by Western blot. Further, AdPlus-mCherry-GFP-LC3 B adenovirus transfection was used to detect the effects of UA on autophagy flux of HCT116 cells; UA combined with autophagy inhibitor chloroquine(CQ) was used to detect the expression of LC3Ⅱ by Western blot. In terms of mechanism, the effect of UA on hedgehog signaling pathway-related proteins in HCT116 cells was detected by Western blot. The results showed that UA inhibited the activity, proliferation and migration of HCT116 cells. UA enhanced the fluorescence intensity of autophagy in HCT116 cells, while promoting the expression of LC3Ⅱ and inhibiting the expression of P62, in a time and dose dependent manner. UA activated the autophagy in HCT116 cells, which manifested that UA resulted in the accumulation of fluorescence spots and strengthened the fluorescence intensity of autophagosomes; compared with UA alone, UA combined with autophagy inhibitor CQ promoted the expression of LC3Ⅱ. UA reduced the expressions of PTCH1, GLI1, SMO, SHH and c-Myc in hedgehog signaling pathway, while increased the expression of Sufu. In conclusion, our study showed that UA activated autophagy in colorectal cancer HCT116 cells, which was related to the mechanism in inhibiting hedgehog signaling pathway activity.

OBJECTIVE To investigate the therapeutic effect of scutellarin on colitis-associated cancer (CAC) and its underlying mechanism based on Wnt/β-catenin signaling pathway. METHODS The mouse model of CAC was estab?lished by azomethane oxide (AOM) and sodium dextran sulfate (DSS), followed by scutellarin treatment, with recording the body weight, diarrhea and hematochezia. After sacrificing the mice, the colorectal length and colorectal tumor were assessed. The levels of pro-inflammatory factors TNF-α and IL-6 in mice's sera were measured by the enzyme-linked immunosorbent assay (ELISA). The colorectal lesions were appraised by hematoxylin and eosin (H&E) staining. Theβ-catenin level in CAC tissues was probed by immunofluorescent analysis. The apoptosis-related genes Bax and Bcl-2, and Wnt signaling pathway-related genes β-catenin, GSK-3β, TCF4, c-Myc and cyclin D1 were detected by real-time quantitative RT-PCR (RT-qPCR). Finally, Western blotting analysis (WB) was employed to examine the expressions of the apoptosis and Wnt signaling pathway-related proteins. RESULTS Scutellarin significantly improved AOM/DSS-caused weight loss, colorectal length shortening, and tumor growth in mice (P<0.01). Meanwhile, colorectal lesions could be substantially alleviated by scutellarin. ELISA results showed that the levels of pro-inflammatory factors TNF-αand IL-6 were drastically lessened (P<0.01). Scutellarin also sharply inhibited the nuclear translocation of β-catenin, as evidenced by the reduction in the nuclear level ofβ-catenin protein. In addition, scutellarin attenuated the mRNA expres?sion of Wnt signaling pathway-relatedβ-catenin, TCF4, c-Myc and cyclin D1, whereas it heightened GSK-3βmRNA level. These results were consolidated by WB analysis, which indicated that scutellarin could mitigate the protein levels of phospho-GSK-3β,β-catenin, TCF4, c-Myc and cyclin D1, with the increase in GSK-3β protein in CAC tissue. Moreover, scutellarin could induce the apoptosis of CAC, demonstrated by enhanced expression of Bax and diminished expression of Bcl-2 in both mRNA and protein levels. CONCLUSION Scutellarin may ameliorate colitis-associated colorectal cancer by weakening Wnt/β-catenin signaling cascade.

OBJECTIVE To identify the inhibitory effect of ursolic acid on the colorectal cancer HCT116 cells in vitro and in vivo, and to explore the underlying mechanism. METHODS The smoothened (SMO) gene-silenced human colorectal cancer HCT116hSMO- cell line was established by transfection with the lentivirus carrying SMO shRNA. The cytotoxic effect of ursolic acid on HCT116hSMO-cells was determined by MTT assay. The effect of ursolic acid on the migration of HCT116hSMO- cells was studied by wound healing assay. The effect of ursolic acid on apoptosis of HCT116hSMO-cells was explored by Hoechst33342/PI double staining and flow cytometry. The effects of ursolic acid on the expressions of apoptotic marker gene Bcl-2, Bax, caspase-3 and caspase-9 were measured by real-time quantitative RT-PCR (RT-qPCR) and Western blotting (WB) analysis. RT-qPCR and WB were used to examine the relationship between GLI1, c-Myc expression and PI3K/Akt pathway to further investigate the mechanism of GLI1 activation in HCT116hSMO- cells. The effects of ursolic acid on the expressions of GLI1, p-Akt, Akt, c-Myc, SHH and SUFU of nonca?nonical Hedgehog pathway were evaluated by RT-qPCR and WB assays. Xenograft nude mouse model bearing HCT116hSMO- cells was established and intraperitoneally treated with ursolic acid to investigate the effect on tumor growth in vivo. The body weight and tumor size of mice were assessed regularly every 2 d. The effect of ursolic acid on the apoptosis of tumor tissue was determined by TUNEL assay. The expressions of Bcl-2, Bax, GLI1, p-Akt, Akt, c-Myc, SHH, SUFU mRNA and proteins were measured by RT-qPCR and WB. The levels of Bcl-2, Bax, GLI1, p-Akt, c-Myc and SHH proteins in tumor tissues were also evaluated by immunohistochemistry. RESULTS Ursolic acid significantly inhibited the growth and migration of HCT116hSMO-cells in vitro, compared with the control (P<0.05). Meanwhile, ursolic acid also induced apoptosis of HCT116hSMO- cells in vitro (P<0.05). Furthermore, SC79 (Akt activator) enhanced the expressions of p-Akt, GLI1 and c-Myc, which could be abolished by ursolic acid, and the effect was equal to Akt inhibitor LY294002. The expressions of Bcl-2, GLI1, p-Akt, c-Myc, SHH mRNA and proteins were reduced by ursolic acid, while the levels of Bax and SUFU were increased. Ursolic acid could inhibit the growth and induce the apoptosis of colorectal cancer xeno?graft in vivo. Similarly, lower levels of Bcl-2, GLI1, p-Akt, c-Myc and SHH, and higher expression of Bax and SUFU were noted in ursolic acid-treated mice. CONCLUSION Ursolic acid can inhibit the growth and induce apoptosis of HCT116hSMO- cells both in vitro and in vivo. And the mechanism is related to the suppression of PI3K/Akt-mediated noncanonical Hedgehog signaling pathway.

Pulsatilla chinensis is a widely used traditional Chinese herb, which contains 56 types of chemical constit?uents, mainly including triterpenoid saponins, organic acids, coumarins and lignans. The largest portion of the ingredi?ents in Pulsatilla chinensis is the family of triterpenoid saponins, in which anemoside B4 is the major effective compound and indexing component. The main components of Pulsatilla chinensis can metabolize into a vast array of active prod?ucts in vivo, which play vital roles in its biological activity. Mounting evidence reveals that Pulsatilla chinensis exerts a wide range of therapeutic activities, such as anti-cancer, immunoregulation, anti-inflammation and anti-schistosome, with fewer adverse reactions, via various signaling pathways and multiple targets. It was documented that the active ingre?dient of Pulsatilla chinensis can lessen the drug resistance and synergize the effects of other natural products includ?ing paclitaxel, as well as ameliorate the clinical efficacy of chemical drugs, such as adriamycin. However, Pulsatilla chi?nensis was also reported to be possibly the main cause of hemolysis and chronic liver injury. The efforts should be made to deeply investigate the pharmacological actions and underlying mechanisms of Pulsatilla chinensis, with a focus on the anti-cancer efficacy, and develop new drugs based on the components of Pulsatilla chinensis for future utilization in the clinical setting.
