This article systematically reviews and examines the historical evolution of Bambusae Succus as a medicinal material， covering aspects such as nomenclature， origin， geographical distribution， harvesting and processing methods， quality assessment， therapeutic effects and indications， by consulting ancient herbal texts， medical compendia， and modern literature. The aim is to provide a reference for the development and utilization of famous classical formulas containing this herb. Research indicated that Bambusae Succus was first documented in the Shennong Bencaojing during the Han dynasty， with Zhuli being the standard name used throughout history， alongside aliases like Zhuzhi， Zhuyou and Huoquan. Historically， the primary source of Bambusae Succus has been Phyllostachys nigra var. henonis（Danzhu）， although other species such as Pleioblastus amarus and Bambusa emeiensis have also been used medicinally. Ancient records predominantly noted its origin in Yizhou（present-day Chengdu and surrounding areas in Sichuan） and the Wuling region（between present-day Hunan， Guangdong， Guangxi and Jiangxi provinces）， while contemporary sources are mainly from regions south of the Yangtze River and southwestern China. Traditionally， Bambusae Succus was harvested from bamboo that had grown for exactly one year， today， it can be collected year-round without strict age requirements. Ancient preparation methods included direct fire roasting or dry distillation， whereas modern industrial production employs dry distillation， reflux extraction， and percolation. In terms of quality evaluation， ancient texts considered a sweet taste to be superior， while today， clarity and transparency are prioritized. Historically， Bambusae Succus was characterized as sweet and cold nature， targeting the lung and stomach meridians， with uses evolving from clearing heat and resolving phlegm to nourishing Yin， moistening dryness， and relaxing tendons and unblocking meridians. Modern descriptions classify it as sweet， bitter， and cold in nature， affecting the heart， liver， and lung meridians， with functions including clearing heat， resolving phlegm， and facilitating orifices. It is indicated for conditions such as stroke with phlegm confusion， lung heat with phlegm congestion， convulsions， epilepsy， excessive phlegm in febrile diseases， high fever with thirst， irritability during pregnancy， and tetanus， with more clearly defined applications. Based on the results of the research， it is recommended that when developing and utilizing famous classical formulas containing Bambusae Succus， the one-year-old Phyllostachys nigra var. Henonis， which has been highly praised throughout history， should be selected as the source material. Industrial production should adopt the dry distillation method. Furthermore， in-depth research should be conducted on the modern technological characterization of the traditional quality control indicator of sweet taste， and reasonable modern quality control standards should be established.

Objective:To investigate the effect of DExH-box helicase 9(DHX9)O-linked N-acetylglucosamine(O-GlcNAc)modifi-cation(O-GlcNAcylation)on the proliferation of hepatitis B virus(HBV)-associated hepatoma cells.Methods:The pAdTrack-TO4-DHX9-3Flag recombinant adenovirus plasmid was constructed by molecular cloning and transfected into HEK293 cells for packaging and amplification of the recombinant adenovirus AdDHX9.The interaction between DHX9 and O-GlcNAc transferase(OGT)was con-firmed using co-immunoprecipitation.The co-localization between DHX9 and OGT was measured by immunofluorescence.The level of DHX9 O-GlcNAcylation was determined using succinylated wheat germ agglutinin(sWGA)and glycosylated immunoprecipitation(IP).The effect of DHX9 O-GlcNAcylation on the proliferation of HBV-associated hepatoma cells was assessed using the colony-forming assay and cell growth curves.Results:The recombinant adenovirus AdDHX9 was successfully obtained,and DHX9 expression was confirmed by Western blot.DHX9 interacted with OGT,and the two proteins were co-localized on the nucleus.The sWGA and gly-cosylated IP experiments showed that DHX9 underwent O-GlcNAcylation,which was further enhanced by HBV infection.The colony-forming assay demonstrated that the number of cell clones was increased in the AdDHX9 group(386.667±15.630)compared with the AdGFP control group(142.667±7.572,P<0.001).Moreover,cell growth curves demonstrated that the overall cell growth rate was en-hanced in the AdDHX9 group(22.860±0.770)compared with the AdGFP control group(13.670±0.517,P<0.001).Conclusion:HBV infection promotes DHX9 O-GlcNAcylation,which enhances the proliferation of HBV-associated hepatoma cells.

Objective To analyze the development of nuclear medicine services in Hunan Province and to assess internal radiation doses among the nuclear medicine workers (NMWs) involved in iodine-131 radionuclide therapy. Methods Based on a survey of nuclear medicine institutions in Hunan Province, a total of 61 NMWs from seven hospitals providing iodine-131 therapy for thyroid cancer were selected as the study subjects by convenience sampling method. Thyroidal iodine-131 activity was measured using a portable gamma spectrometer to estimate internal dose and total annual effective dose. Results A total of 47 nuclear medicine institutions were reported in Hunan Province by 2023, most of which were public and tertiary hospitals, accounting for 38. Iodine-131 therapy was performed in 30 institutions, including nine for thyroid cancer. A total of nine participants had detectable thyroidal iodine-131 activity among 61 workers involved in iodine-131 thyroid cancer treatment, with the detection rate of 14.8%. Their internal radiation annual committed effective doses ranged from 0.100 to 1.584 mSv, with a mean of 0.499 mSv and median of 0.426 mSv. Except for one cleaner, the remaining eight physicians and nurses had the total annual effective doses ranging from 0.311 to 3.007 mSv, with a mean of 1.305 mSv, all below the annual dose limit of 20.000 mSv among radiation workers specified in national standard. Conclusion Internal exposure to iodine-131 among the NMWs should not be neglected. Standardized procedures and strengthened internal dose monitoring are recommended.

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Objective To explore the computed tomography angiography(CTA)and clinical features of Takayasu's arteritis(TA)with peripheral artery involvement.Methods In this retrospective study,CTA scan was performed in a total of 184 TA patients.TA patients were divided into two groups:60 patients within peripheral artery involvement(peripheral artery involvement group)and 124 patients without peripheral artery involvement(peripheral artery non-involvement group).The difference in comparison of clini-cal data and CTA findings were analyzed.Results A total of 194 peripheral arteries were involved in 60 patients.The most suscep-tible peripheral artery were axillary artery(52,26.8％),middle cerebral artery(26,13.4％)and femoral artery(22,11.3％).In the peripheral artery involvement group,the most common CTA manifestation was luminal stenosis(141,72.7％).The lumen dilata-tion,lumen stenosis with dilatation and wall calcification were not easy to be observed.The age and duration of disease in peripheral artery involvement group were significantly greater than those in peripheral artery non-involvement group(P＜0.05).The proportion of the peripheral artery involvement group in the active phase was significantly lower than that of the peripheral artery non-involvement group(P＜0.05).The incidence of pain in the limbs in peripheral artery involvement group was significantly higher than that in peripheral artery non-involvement group(P＜0.05).The utilization rate of tocilizumab in the peripheral artery involvement group was significantly higher than that in the peripheral artery non-involvement group(P＜0.05).Conclusion TA involving peripheral arteries is more common in patients with a long course of disease and in the inactive phase.Patients are prone to pain in their limbs.The CT A manifestations of these patients are also special,that is,the involved peripheral arteries are not prone to lumen dilatation and wall calcification.

Objective:To study the role and mechanism of heat shock protein 70 (HSP70) in apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3B (APOBEC3B)-mediated inhibition of hepatitis B virus(HBV) replication.Methods:The interaction between HSP70 and APOBEC3B was analyzed by co-immunopreciptation (Co-IP) and GST pull-down. After treating Huh7 cells with siHSP70 or HSP70 inhibitor VER155008 or overexpressing HSP70 in Huh7 cells, changes in the antiviral effect of APOBEC3B were detected by Southern blot and real-time PCR; the deaminase activity of APOBEC3B was tested by differential DNA denaturation PCR(3D-PCR) and clone sequencing.Results:HSP70 could bind to APOBEC3B. Overexpression of HSP70 promoted the deaminase activity and anti-HBV activity of APOBEC3B. On the contrary, knockdown of HSP70 or using HSP70 inhibitor VER155008 would attenuate the deaminase activity and anti-HBV activity of APOBEC3B.Conclusions:HSP70 could promote the anti-HBV activity of APOBEC3B by enhancing the deaminase activity of APOBEC3B.

Chronic hepatitis B virus (HBV) infection is one of the leading causes of hepatocellular carcinoma (HCC). Ubiquitin-proteasome system (UPS) mediates the post-translational modification and degradation of protein in eukaryotic cells. Recent studies have revealed that UPS plays an important role in HBV infection and hepatocarcinogenesis. Targeting HBx to intervene in the progression of HBV infection or HBV-related HCC has become a research hotspot both domestically and internationally in recent years. This article reviewed the progress in HBx promoting HBV infection and hepatocarcinogenesis through UPS.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Objective To analyze the immunological effect and its influencing factors of HAART on HIV/AIDS with a baseline CD4 of less than 350 cells/mm³ in Hubei Province during 2011-2020. Methods The treatment information of people living with HIV/AIDS (PLWH) was collected through China Disease Control and Prevention Information System, and the change of CD4 mean value was analyzed by Wilcoxon sign rank sum test. Chi square test and multivariate logistic regression were used to analyze the factors influencing the immunological effect. Results The mean value of CD4 cell count at baseline was (172.78±107.65) cells/mm3 before treatment and (398.85±206.71) cells/mm³ in the fifth year after treatment. Patients with baseline CD4<50 /mm3 had the largest increase in CD4 mean value after treatment (P<0.05). Multivariate logistic regression analysis showed that Age ≥35 years, heterosexual transmission, time interval from diagnosis to treatment≥1 month, baseline CD4<50 /mm3, treatment time 7-<18 months, and drug failure were the risk factors for the success of antiviral therapy(P<0.05). Conclusion The immunological effect of HIV/AIDS antiviral therapy in Hubei Province is affected by many factors. It is necessary to strengthen the implementation of early detection and early treatment strategy and promote treatment compliance education for patients aged ≥35 years.
