Hepatocellular carcinoma (HCC) is an aggressive human cancer with increasing incidence worldwide. Multiple efforts have been made to explore pharmaceutical therapies to treat HCC, such as targeted tyrosine kinase inhibitors, immune based therapies and combination of chemotherapy. However, limitations exist in current strategies including chemoresistance for instance. Tumor initiation and progression is driven by reprogramming of metabolism, in particular during HCC development. Recently, metabolic associated fatty liver disease (MAFLD), a reappraisal of new nomenclature for non-alcoholic fatty liver disease (NAFLD), indicates growing appreciation of metabolism in the pathogenesis of liver disease, including HCC, thereby suggesting new strategies by targeting abnormal metabolism for HCC treatment. In this review, we introduce directions by highlighting the metabolic targets in glucose, fatty acid, amino acid and glutamine metabolism, which are suitable for HCC pharmaceutical intervention. We also summarize and discuss current pharmaceutical agents and studies targeting deregulated metabolism during HCC treatment. Furthermore, opportunities and challenges in the discovery and development of HCC therapy targeting metabolism are discussed.

ObjectiveTo explore the role of transient receptor potential vanilloid 1 (TRPV1) channel in reducing cardiomyocyte toxicity of Aconiti Kusnezoffii Radix processed with Chebulae Fructus. MethodH9c2 cardiomyocytes cultured in vitro were used as a model to assess cell viability by methyl thiazolyl tetrazolium (MTT) assay, the expression of TRPV1 mRNA was detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), and the leakage rate of lactate dehydrogenase (LDH), the changes of nucleus, reactive oxygen species (ROS), mitochondrial membrane potential and Ca2+ contents were detected by enzyme linked immunosorbent assay (ELISA). ResultCompared with the blank group, when the concentration was ≥0.5 g·L-1, the cell viability was significantly decreased (P<0.01), the leakage rate of LDH, the release of ROS and Ca2+ were increased, the mitochondrial membrane potential was decreased, and the nucleus was pyknosis or even broken in raw Aconiti Kusnezoffii Radix and Aconiti Kusnezoffii Radix processed with Chebulae Fructus groups. When the concentration was ≥0.5 g·L-1, compared with the same mass concentration of raw Aconiti Kusnezoffii Radix group, the cell viability increased significantly (P<0.01), the leakage rate of LDH, the release of ROS and Ca2+ decreased, the mitochondrial membrane potential increased, and the nuclear morphology improved in Aconiti Kusnezoffii Radix processed with Chebulae Fructus group. Application of the same mass concentration of raw Aconiti Kusnezoffii Radix to H9c2 cardiomyocytes pretreated with the TRPV1 inhibitor BCTC significantly increased cell viability, decreased leakage rate of LDH, ROS and Ca2+ release, increased mitochondrial membrane potential and improved nuclear pyknosis compared with untreated H9c2 cardiomyocytes. Application of the same mass concentration of Aconiti Kusnezoffii Radix processed with Chebulae Fructus to H9c2 cardiomyocytes pretreated with BCTC decreased cell viability, increased LDH leakage rate, ROS and Ca2+ release, reduced mitochondrial membrane potential compared with untreated H9c2 cardiomyocytes. Real-time PCR results showed that both raw Aconiti Kusnezoffii Radix and Chebulae Fructus decoction could increase the expression of TRPV1 mRNA in cardiomyocytes in a concentration dependent manner. ConclusionRaw Aconiti Kusnezoffii Radix can induce cardiomyocyte apoptosis and cardiotoxicity by activating TRPV1 channel, while Aconiti Kusnezoffii Radix processed with Chebulae Fructus can attenuate the toxicity through TRPV1 channel, which may be related to the synergistic effect of acid components in Chebulae Fructus and alkaloids in Aconiti Kusnezoffii Radix on TRPV1 channel.

Journal of Peking University(Health Sciences) 2022;54(5):954-960
OBJECTIVE:
To analyze the disease spectrums underlying orthostatic intolerance (OI) and sitting intolerance (SI) in Chinese children, and to understand the clinical empirical treatment options.
METHODS:
The medical records including history, physical examination, laboratory examination, and imagological examination of children were retrospectively studied in Peking University First Hospital from 2012 to 2021. All the children who met the diagnostic criteria of OI and SI were enrolled in the study. The disease spectrums underlying OI and SI and treatment options during the last 10 years were analyzed.
RESULTS:
A total of 2 110 cases of OI and SI patients were collected in the last 10 years, including 943 males (44.69%) and 1 167 females (55.31%) aged 4-18 years, with an average of (11.34±2.84) years. The overall case number was in an increasing trend over the year. In the OI spectrum, postural tachycardia syndrome (POTS) accounted for 826 cases (39.15%), followed by vasovagal syncope (VVS) (634 cases, 30.05%). The highest proportion of SI spectrum was sitting tachycardia (STS) (8 cases, 0.38%), followed by sitting hypertension (SHT) (2 cases, 0.09%). The most common comorbidity of OI and SI was POTS coexisting with STS (36 cases, 1.71%). The highest proportion of treatment options was autonomic nerve function exercise (757 cases, 35.88%), followed by oral rehydration salts (ORS) (687 cases, 32.56%), metoprolol (307 cases, 14.55%), midodrine (142 cases, 6.73%), ORS plus metoprolol (138 cases, 6.54%), and ORS plus midodrine (79 cases, 3.74%). The patients with POTS coexisting with VVS were more likely to receive pharmacological intervention than the patients with POTS and the patients with VVS (41.95% vs. 30.51% vs. 28.08%, χ2= 20.319, P < 0.01), but there was no significant difference in the proportion of treatment options between the patients with POTS and the patients with VVS.
CONCLUSION
POTS and VVS in children are the main underlying diseases of OI, while SI is a new disease discovered recently. The number of children with OI and SI showed an increasing trend. The main treatment methods are autonomic nerve function exercise and ORS. Children with VVS coexisting with POTS were more likely to take pharmacological treatments than those with VVS or POTS only.

OBJECTIVE:
Improvement in the quality of life is reflected in the narrowing of the gap between health-adjusted life expectancy (HALE) and life expectancy (LE). The effect of megacity expansion on narrowing the gap is rarely reported. This study aimed to disclose this potential relationship.
METHODS:
Annual life tables were constructed from identified death records and population counts from multiple administrative sources in Guangzhou, China, from 2010 to 2020. Joinpoint regression was used to evaluate the temporal trend. Generalized principal component analysis and multilevel models were applied to examine the county-level association between the gap and social determinants.
RESULTS:
Although LE and HALE in megacities are increasing steadily, their gap is widening. Socio-economic and health services are guaranteed to narrow this gap. Increasing personal wealth, a growing number of newborns and healthy immigrants, high urbanization, and healthy aging have helped in narrowing this gap.
CONCLUSION
In megacities, parallel LE and HALE growth should be highly considered to narrow their gap. Multiple social determinants need to be integrated as a whole to formulate public health plans.

Lower respiratory tract infection (LRTI) induced by respiratory syncytial virus (RSV) is an important cause of hospitalization for infants. Compared with adults, infants are more likely to cause serious respiratory diseases after RSV infection due to the specific immature airway structure and immune system. The balance of immune resistance and immune tolerance of the host is critical to effective virus clearance and disease control. This paper reviews the relationship between RSV infection and respiratory diseases in infancy, the influence factors of the high pathogenicity of RSV infection in early life, as well as the research progress of anti-RSV therapy, and expands the specific molecular events regulating immune resistance and immune tolerance. We expect to present new ideas for the prevention and treatment of RSV-related respiratory diseases in clinical practice.

Aurantii Fructus is a commonly used qi-regulating medicinal herb in China. Both traditional Chinese medicine theory and modern experimental research demonstrate that Aurantii Fructus has dryness effect, the material basis of which remains unclear. In recent years, spectrum-effect relationship has been widely employed in the study of active ingredients in Chinese medicinal herbs, the research ideas and methods of which have been constantly improved. Based on the idea of spectrum-effect study, the ultra-high perfor-mance liquid chromatography-quadrupole-time of flight mass spectrometry(UHPLC-Q-TOF-MS) fingerprints of different fractions of Aurantii Fructus extract were established for the identification of total components. Then, the dryness effects of the fractions on normal mice and gastrointestinal motility disorder(GMD) rats were systematically compared. Finally, principal component analysis(PCA), Pearson bivariate correlation analysis and orthogonal partial least squares analysis(OPLS) were integrated to identify the dryness components of Aurantii Fructusextract. The results showed that narirutin, naringin, naringenin, poncirin, oxypeucedanin, and eriodictyol-7-O-glucoside had significant correlations with and contributed to the expression of AQP2 in kidney, AQP3 in colon, and AQP5 in submandibular gland, which were the main dryness components in Aurantii Fructus.

Objective:To investigate the effect of repetitive transcranial magnetic stimulation (rTMS) on the cognition of patients with mild cognitive impairment (MCI).Methods:The PubMed, Cochrane Library, Embase, Web of Science, CNKI, Wanfang, and VIP databases were searched for randomized controlled trials of rTMS treating MCI patients before March 2019. After screening the literature, extracting the data and two independent reviewers evaluating the quality of the included studies, the meta-analysis was conducted using version 5.3 of the RevMan software.Results:Nine studies covering 368 patients were included. The pooled results showed that compared with sham stimulation, rTMS treatment could effectively improve the cognitive ability (assessed using the Montreal instrument), episodic memory, verbal fluency and the amplitude of MCI patients′ P300 signals. P300 latency was also reduced. However, there was no significant difference, on average, in memory quotient or P300 latency between patients given rTMS plus donepezil hydrochloride and those given donepezil hydrochloride alone. Compared with the control groups, the rTMS treatment groups displayed slightly more frequent adverse reactions, mainly mild dizziness and scalp pain which disappeared within 1-2 hours without obvious residual effects.Conclusions:TMS treatment can effectively improve cognitive and memory function.

To investigate the effects of miR-31 on TLR4/NF-κB signaling pathway and apoptosis-related proteins in dextran sulfate sodium (DSS) induced mouse colon colitis. Methods: ① Mouse model of colon colitis: 1% DSS was used to induce mouse ulcerative colitis (UC). Fourteen FVB non-transgenic mice were randomly divided into control group (n= 6), DSS group (n= 8), and 16 FVB miR-31 transgenic mice were randomly divided into miR-31 overexpression group (n= 8), miR-31 overexpression +DSS group (n= 8). DSS was dissolved in water and administered to mice by drinking water. The DSS group and miR-31+DSS group drank 1% DSS water in the first week, normal sterilized water in the second week, and 1% DSS water in the third week, after 5 weeks, the modeling was completed, then the colon tissues of the mice were collected. Western blot and IHC were used to detect the expressions of NF-κB p65, TLR4, Bax and Bcl-2 proteins in mouse colon tissue, TUNEL was used to detect apoptosis of mouse colon tissues. ② Cell culture experiments: Transfection of miR-31mimic and inhibitor by lipofectamine resulted in overexpression or knockdown of miR-31 in human colon epithelial cell line HCT 116 cells, each group was repeated three times and cells were collected 48 h later, Western blot was used to detect the expressions of NF-κB p65 and TLR4 protein. ① In animal experiments, compared with the control group, the expression levels of NF-κB p65, TLR4 protein and apoptotic cell index in the DSS group and miR-31 overexpression group in mouse colon tissue were significantly increased (P<0.05 or P<0.01), and the Bcl-2 / Bax ratio was significantly reduced (P<0.05 or P<0.01); and compared with the DSS group, the expression levels of NF-κB p65, TLR4 protein and apoptotic cell index in the miR-31+DSS group were significantly increased (P<0.01), while the Bcl-2/Bax ratio was significantly decreased (P<0.01). ② In cell experiments, compared with the control group, the expression levels of NF-κB p65 and TLR4 protein in the over-expressed miR-31 group of HCT 116 cells were significantly increased (P<0.05 or P<0.01), the expressions of NF-κB p65 and TLR4 protein in miR-31 knockdown group were decreased (P<0.05). miR-31 promotes the development of colitis by promoting TLR4/NF-κB signaling pathway and mediating apoptosis of intestinal epithelial cells.

Objective:
Moxifloxacin (MFX) shows good activity against and can be a possible antibiotic therapy to treat infection; however, other studies have shown a lower or no activity. We aimed to evaluate MFX activity against using zebrafish (ZF) model .
Methods:
A formulation of labeled with CM-Dil was micro-injected into ZF. Survival curves were determined by recording dead ZF every day. ZF were lysed, and colony-forming units (CFUs) were enumerated. Bacteria dissemination and fluorescence intensity in ZF were analyzed. Inhibition rates of MFX and azithromycin (AZM, positive control) were determined and compared.
Results:
Significantly increased survival rate was observed with different AZM concentrations. However, increasing MFX concentration did not result in a significant decrease in ZF survival curve. No significant differences in bacterial burdens by CFU loads were observed between AZM and MFX groups at various concentrations. Bacterial fluorescence intensity in ZF was significantly correlated with AZM concentration. However, with increasing MFX concentration, fluorescence intensity decreased slightly when observed under fluorescence microscope. Transferring rates at various concentrations were comparable between the MFX and AZM groups, with no significant difference.
Conclusion
MFX showed limited efficacy against using ZF model. Its activity needs to be confirmed.

This paper was aimed to observe the effect of anemoside B4(hereinafter referred to as B4) on cisplatin-induced acute kidney injury in mice, and to investigate its possible mechanism in renal protection from inflammation and apoptosis aspects. Mice were divided into normal group, model group, dexamethasone positive group and B4 high, middle and low dose groups(5, 2.5, and 1.25 mg·kg~(-1 )doses). All the other mice groups except normal group were given with tail vein injection of cisplatin(15 mg·kg~(-1)) to induce acute kidney injury models. The drug administration was started on the day of modeling, and lasted for 4 days. After 1 hour of the last injection, orbital blood was collected. After the serum was separated, serum urea nitrogen(BUN), creatinine(Cre), total protein(TP), and albumin(ALB) were tested by using an automatic biochemical analyzer; the changes of kidney pathological morphology were observed by PAS staining; the protein expression levels of inflammatory factors including nucleotide binding oligomerization domain-like receptor(NLRP3), cysteinyl aspartate specific proteinase 1(caspase-1), interleukin-18(IL-18), interleukin-1β(IL-1β), tumor necrosis factor(TNF-α), and interleukin-6(IL-6) and apoptosis factors including p53, caspase-3, cleaved-caspase-3, Bcl-2 associated X protein(Bax), and B-cell lymphoma-2(Bcl-2) were analyzed by Western blot. The results showed that B4 significantly reduced the serum BUN and Cre contents, and alleviated pathological changes in renal tissues, such as the shedding and degeneration of renal tubular epithelial cells, tubulin tubule type. B4 significantly down-regulated the protein expressions of p53, Bax, cleaved-caspase-3 in the kidney and up-regulated the expression of Bcl-2/Bax. In model group, however, no significant up-regulation was observed in the protein expression levels of inflammatory cytokines(NLRP3, pro-caspase-1, IL-18, IL-1β, TNF-α, IL-6). The results suggested that B4 had a certain protective effect on cisplatin-induced acute kidney injury, and could activate p53 signaling pathway related apoptotic factors. B4 renal protective effect was mainly related to the regulation of p53 signaling pathway, while NLRP3 inflammasome and related inflammatory factors had no obvious response in this model.
