ObjectiveTo study the characteristics of imprinting template of flavonoid clusters in four Chinese medicines attributed to the lung meridian， and to establish an in vitro experimental approach for the study of the attribution of Chinese medicines to the lung meridian. MethodBased on 13 Chinese medicines， including Xanthii Fructus， Houttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and so on， which only belong to the lung meridian in Chinese Materia Medica（the 13th Five-Year planning textbook of general higher education）， we identified four representative Chinese medicines， namely Houttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and Mori Cortex， and set up their fingerprints by high performance liquid chromatography（HPLC） and calculated the molecular connectivity indices of various components in the four Chinese medicines， the similarity to their mean value was calculated by included angle cosine method， so as to establish the quantitative relationship of construction versus imprinting ability， and to determine the order of each component in the lung meridian. A total of 7 reference substances， including chlorogenic acid， rutin， quercetin， isoquercitrin， hyperoside， epicatechin， and iridin， were selected to validate the overall conformational relationships of flavonoids of the model， as well as its predictive ability. ResultHouttuyniae Herba， Fagopyri Dibotryis Rhizoma， Belamcandae Rhizoma and Mori Cortex contained a total of 437 chemical components with an average molecular connectivity index similarity of 0.995 6. The four Chinese medicines contained a total of 204 flavonoids with an average molecular connectivity index similarity of 0.978 0， which was second only to the alkaloids with 0.985 1. The retention time（tR） of the 7 reference substances showed a good conformational relationship with the similarity of the molecular connectivity index（tR=831.4×S-790.3， r=0.861 4， P<0.01）， which was applicable to the in vitro attribution study of the position， similarity， and relative similarity with tR of the cluster of 98.04% of flavonoids. Accordingly， the 1st position was kuwanon D， with a similarity of molecular connectivity index of 0.987 7 and a tR of 30.88 min， the 200th position was chlorogenic acid， with a similarity of molecular connectivity index of 0.958 2 and a tR of 6.36 min. The total first-order moment of the four Chinese medicines calculated by total statistical moment method of fingerprint was 24.26 min， ranked 21， which could characterize 99.19% of the whole， and the total first-order moment of the total peak area of the 7 reference substances in the four Chinese medicines was 20.00 min， with a rank of 46， which could characterize 98.68% of the whole. ConclusionFlavonoid clusters are suitable probes for the characterization of imprinting template for the study of the lung meridian， which can be established a quantitative imprinting method for meridian tropism of Chinese medicines in vitro.

Myocardial fibrosis （MF） is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells， the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself， and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research， scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system （RAAS） system and the inflammatory process， repairing the extracellular matrix， managing oxidative stress， and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process， macrophage activation is beneficial， but excessive activation will be harmful. In the early stage of MF， appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF， appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient， or the balance of M1/M2 macrophage polarization is broken， the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin， as well as regulating Qi and activating blood， but there are also some heat-clearing， dampness-drying， and detoxification products. Therefore， the occurrence of MF may be caused by Qi and Yin deficiency， damp heat accumulation， and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF， this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF， so as to provide a reference for the treatment of MF with traditional Chinese medicine.

Triple-negative breast cancer (TNBC) is a type of breast cancer that is difficult to treat, has a poor prognosis, and is prone to recurrence and metastasis in the early postoperative period. The age of patients is tending younger, and the racial difference is large. It is also related to family history, and genetic susceptibility is obvious. So, elucidating the genetic risk factors of TNBC and obtaining precise therapeutic targets are urgent tasks. Obtaining reliable characteristic genes and their polymorphisms between TNBC of different subtypes is difficult. This review summarizes the susceptibility genes and the polymorphisms of TNBC susceptibility genes of different molecular subtypes, in order to develop effective TNBC prevention strategies and find effective therapeutic targets. This review provides a theoretical basis for promoting the study of TNBC from the perspective of genetics.

Objective:A novel bile duct end-to-end anastomosis and percutaneous transhepatic cholangial drainage (PTCD) were designed to treat iatrogenic bile duct injuries, and the clinical efficacy and technical advantage of this combined treatment were analyzed.Methods:Clinical data from 11 patients with iatrogenic bile duct injuries treated between February 2012 to July 2021 was retrospectively analyzed. There were 4 females and 7 males, with age of (47.5±15.3) years old. The types of bile duct injuries were: Bismuth type 1 ( n=7), Bismuth type Ⅱ ( n=1), Bismuth type Ⅲ type ( n=1), combined Bismuth type 1 and type 2 ( n=1), and Bismuth type Ⅳ ( n=1). Repair operations were performed at the time of the initial surgical procedures in 8 patients. The remaining 3 patients had their repair done 2 days, 9 days and 5 months, respectively, after the initial operations. All patients underwent successful bile duct end-to-end anastomosis and PTCD without use of T-tubes. Results:All biliary injuries were successfully repaired with no operative mortalities. Two patients who underwent end-to-end anastomosis of common hepatic duct developed anastomotic bile leakage. The amount of bile leakage was small and bile leakage resolved with conservative treatment in 1 patients 3 days after surgery, and was treated successfully by percutaneous peritoneal drainage for 2 weeks in the other patient. There were no other complications, including stricture formation or cholangitis which developed in other patients. All patients’ liver functions recovered well. The percutaneous biliary drainage tube was removed 6 months after operation in 1 patient. The remaining patients had their drainage tubes removed 3 months after operation. On follow-up, all patients had no history suggestive of cholangitis, jaundice and other symptoms. The liver functions were normal on laboratory examinations. No stricture or dilatation of intrahepatic bile ducts were detected on imaging examinations. The cure rate was 100% (11/11).Conclusion:Surgical repair of biliary tract injuries should aim to preserve sphincter of Oddi function and maintain normal physiological pathway of bile excretion. PTCD helped smooth recovery of an end-to-end anastomosis, lowered severity of physical disability of patients and minimized occurrence of medical disputes.

Polyhydroxyalkanoate (PHA) is a family of biodegradable polyesters synthesized by microorganisms. It has various monomer structures and physical properties with broad application prospects. However, its large-scale production is still hindered by the high cost. In the past 30 years, metabolic engineering approach has been used to tune the metabolic flux, engineer and introduce pathways. The efficiency of PHA synthesis by microorganisms has been significantly improved, and the diversity of PHA monomer, structure and substrate have also been enriched. Meanwhile, by changing cell morphology and PHA particle size, more efficient downstream production process has achieved and PHA production costs have been reduced. In recent years, "Next generation industrial biotechnology" (NGIB) based on extremophiles, especially halophilic Halomonas spp., has been rapidly developed. NGIB has achieved the opening and continuous production of PHA, which simplifies the production process and saves energy and fresh water. Combined with metabolic engineering, Halomonas spp. can be transformed into low-cost production platform of numerous PHA. It is expected to improve the market competitiveness and promote the commercialization of PHA.

Objective:To investigate the impact of low level viremia (LLV) on the prognosis of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients received anti-retroviral therapy (ART).Methods:From January to December 2015, the HIV/AIDS patients with LLV received ART over one year were recruited in Guangzhou Eighth People′s Hospital, Guangzhou Medical University (LLV group). Patients with viral load (VL) less than 50 copies/mL were matched at ratio of 1∶1 according to gender, age and the transmission route were included in the control group (suppression group). The LLV group was divided into three subgroups according to VL (LLV-1 subgroup was 50-200 copies/mL, LLV-2 subgroup was 201-400 copies/mL, and LLV-3 subgroup was 401-1 000 copies/mL). The influence of LLV on the antiviral response during the following three years was investigated.The Wilcoxon signed rank test, Kruskal-Wallis test and chi-square test were used for statistical analysis.Results:One hundred and thirty-seven patients were enrolled in the LLV group, of whom 111 were males and 26 were females, with age of (39.5±13.5) years old. At the same time, 137 patients were included in the suppression group. There were 93 cases in LLV-1 subgroup, 25 cases in LLV-2 subgroup and 19 cases in LLV-3 subgroup. There were no significant differences in the CD4 + T lymphocyte counts and CD4 + /CD8 + T lymphocyte counts ratios between LLV group and suppression group before ART (both P>0.05). During the three-year follow-up, the cumulative number of viral failures in LLV group (7.3%(10/137)) was significantly higher than that in the suppression group (1.5%(2/137)) ( χ2=5.578, P=0.018). Virological failure occurred in eight patients (8.6%) in the LLV-1 subgroup, two patients (8.0%) in the LLV-2 subgroup, and no patients in the LLV-3 subgroup. There was no statistical significance in the incidence of virological failure among all the subgroups ( P>0.05). At one, two, three years follow-up, the CD4 + T lymphocyte counts increased in both LLV group and suppression group without statistical differences (all P>0.05), and the CD4 + /CD8 + T lymphocyte counts ratios in each LLV group were lower than that in the suppression group ( Z=-3.183, -2.094 and -2.312, respectively, all P<0.05). At one, two, three years follow-up, There were no significant differences in CD4 + /CD8 + T lymphocyte counts ratios among the LLV-1, LLV-2 and LLV-3 subgroups (all P>0.05). Conclusion:HIV/AIDS patients with LLV having received ART over one year are more likely to develop virological failure and delay the recovery of immune function, which requires early relevant interventions.

Objective@#To evaluate the effect of long-chain non-coding RNA TUG1 on the radiosensitivity of cervical cancer cells and explore its underlying mechanism.@*Methods@#The expression of TUG1 and miR-145 in cervical cancer cells XB1702 and normal endometrial stromal cells (ESCs) was detected by qRT-PCR. The transfected si-NC, transfected si-TUG1, transfected si-NC combined with irradiation, transfected si-TUG1 combined with irradiation, si-TUG1 and anti-miR-NC co-transfected and, si-TUG1 and anti-miR-145 co-transfected groups were established, which were transfected into XB1702 cells by liposome method. The survival fraction of each group was detected by colony formation assay. The cell apoptosis of each group was detected by flow cytometry. The fluorescence activity of each group was assessed by dual luciferase reporter gene assay.@*Results@#Compared with the normal ESCs, the expression of TUG1 was significantly up-regulated, whereas that of miR-145 was significantly down-regulated in the cervical cancer cells XB1702. Silencing TUG1 significantly increased the survival fraction of XB1702 cells, promoted cell apoptosis and enhanced the radiosensitivity of irradiation to XB1702 cells. TUG1 could target and regulate the expression of miR-145. Suppressing miR-145 reversed the silencing effect of TUG1 on inhibiting proliferation, accelerating apoptosis promotion and enhancing sensitization of XB1702 cells.@*Conclusions@#Silencing long-chain non-coding RNA TUG1 can enhance the radiosensitivity of cervical cancer cells. The mechanism may be related to targeting miR-145, which will provide a target for radiotherapy of cervical cancer.
