OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

OBJECTIVE: Varied acupoint selections represent a potential cause of the uncertainty surrounding the efficacy of acupuncture for knee osteoarthritis (OA). Skin temperature, a guiding factor for acupoint selection, may help to address this issue. This study explored thermal sensitization of acupoints used for the treatment of knee OA. METHODS: This cross-sectional case-control study enrolled cases aged 45-75 years with symptomatic knee OA and age- and gender-matched non-knee OA controls in a 1:1 ratio. All participants underwent infrared thermographic imaging. The primary outcome was the relative skin temperature of acupoint (STA), and the secondary outcome was the absolute STA of 11 acupoints. The Z test was used to compare the relative and absolute STAs between the groups. Principal component analysis was used to extract the common factors (CFs, acupoint cluster) in the STAs. A general linear model was used to identify factors affecting the STA in the knee OA cases. For the group comparisons of relative STA, P < 0.0045 (adjusted for 11 acupoints through Bonferroni correction) was considered to indicate statistical significance. For other analyses, P < 0.05 was used as the threshold for statistical significance. RESULTS: The analysis included 308 participants, consisting of 151 cases (mean age: [64.58 ± 6.67] years; male: 25.83%; mean body mass index: [25.70 ± 3.16] kg/m²) and 157 controls (mean age: [63.37 ± 5.96] years; male: 26.11%; mean body mass index: [24.47 ± 2.84] kg/m²). The relative STAs of ST34 (P = 0.0001), EX-LE2 (P < 0.0001), EX-LE5 (P = 0.0006), SP10 (P < 0.0001), BL40 (P = 0.0012) and GB39 (P = 0.0037) were higher in the knee OA group. No difference was found in the STAs of ST35, ST36, SP9, GB33 and GB34. Four CFs were identified for relative STA in both groups. The acupoints within each CF were consistent between the groups. The mean values of the relative STAs across each CF were higher in the knee OA group. In the knee OA cases, no factors were observed to affect the relative STA, while age and gender were found to affect the absolute STA. CONCLUSION Among patients with knee OA, thermal sensitization occurs in the acupoints of the lower extremity, exhibiting localized and regional thermal consistencies. The thermally sensitized acupoints that we identified in this study, ST34, SP10, EX-LE2, EX-LE5, GB39 and BL40, may be good choices for the acupuncture treatment of knee OA.

Cellulose synthase (CesA), one of the key enzymes in the biosynthesis of cellulose in plants, plays an important role in plant growth and plant resistance. In this study, a total of 21 AsCesA genes from Aquilaria sinensis were systematically identified and the physico-chemical characteristics were analyzed based on genome database and bioinformatical methods. The phylogenetic tree was constructed and the gene location on chromosome, cis-acting elements in the 2 000 basepairs upstream regulatory regions and conservative motifs were analyzed. The AsCesA proteins were mainly located on the plasma membrane. The number of amino acids of the proteins ranged from 390 to 1 261. The isoelectric point distributed from 5.67 to 8.86. All of the 21 AsCesA proteins possessed the transmembrane domains, the number of which was from 6 to 8. The genes were classified into 3 groups according to the phylogenetic relationship. Obvious differences were observed in motif composition in genes from different groups. However, motif2, motif6, motif7 and motif10 were observed in all of AsCesA proteins. Analysis of cis-acting elements indicated that AsCesA genes family has cis-acting elements related to plant hormones, abiotic stresses, and biological processes. Seven AsCesA genes with differential expression were selected according to the calli transcriptome data induced by NaCl at different times and their expression levels under different abiotic stresses were analyzed by quantitative real-time PCR. The results indicated that salt, low temperature, drought, and heavy metal stresses could affect the expression level of AsCesA genes, and the abundance of AsCesA1, AsCesA3 and AsCesA20 showed a significant change, implying their potential important roles to the abiotic stresses. The accumulation pattern of cellulose content under different abiotic stresses was similar to the expression trend of AsCesA genes. Our results provide valuable insights into the role of cellulose synthase in A.sinensis in plant defense.

BACKGROUND: Liver biopsy for the diagnosis of non-alcoholic steatohepatitis (NASH) is limited by its inherent invasiveness and possible sampling errors. Some studies have shown that cytokeratin-18 (CK-18) concentrations may be useful in diagnosing NASH, but results across studies have been inconsistent. We aimed to identify the utility of CK-18 M30 concentrations as an alternative to liver biopsy for non-invasive identification of NASH. METHODS: Individual data were collected from 14 registry centers on patients with biopsy-proven non-alcoholic fatty liver disease (NAFLD), and in all patients, circulating CK-18 M30 levels were measured. Individuals with a NAFLD activity score (NAS) ≥5 with a score of ≥1 for each of steatosis, ballooning, and lobular inflammation were diagnosed as having definite NASH; individuals with a NAS ≤2 and no fibrosis were diagnosed as having non-alcoholic fatty liver (NAFL). RESULTS: A total of 2571 participants were screened, and 1008 (153 with NAFL and 855 with NASH) were finally enrolled. Median CK-18 M30 levels were higher in patients with NASH than in those with NAFL (mean difference 177 U/L; standardized mean difference [SMD]: 0.87 [0.69-1.04]). There was an interaction between CK-18 M30 levels and serum alanine aminotransferase, body mass index (BMI), and hypertension ( P  < 0.001, P  = 0.026 and P  = 0.049, respectively). CK-18 M30 levels were positively associated with histological NAS in most centers. The area under the receiver operating characteristics (AUROC) for NASH was 0.750 (95% confidence intervals: 0.714-0.787), and CK-18 M30 at Youden's index maximum was 275.7 U/L. Both sensitivity (55% [52%-59%]) and positive predictive value (59%) were not ideal. CONCLUSION This large multicenter registry study shows that CK-18 M30 measurement in isolation is of limited value for non-invasively diagnosing NASH.

Objective: To examine the clinical value of fluorescence-guided indocyanine green (ICG) laparoscopic anatomical hepatectomy in the treatment of primary hepatocellular carcinoma. Methods: Data from patients diagnosed with hepatocellular carcinoma and who underwent laparoscopic hepatectomy with ICG fluorescence navigation in the Department of Liver Surgery and Liver Transplantation Center of West China Hospital between September 2020 and May 2022 were retrospectively collected. There were 53 males and 19 females, with an age of (55.5±12.9)years(range:42.6 to 68.4 years). Among them, 13 of the cases underwent laparoscopic anatomical liver resection(LALR) guided by tans-arterial ICG,43 of the cases received LAIR guided by portal vein negative ICG, and 16 of the cases received LALR positive by portal vein. Comparison among the three groups was performed by one-way ANOVA; and the rank sum test was used for comparison between groups. The counting data was expressed as percentage,and the χ² test or Fisher's exact probability method was used for comparison between groups. Results: (1) Postoperative pathology: Resection R0 was achieved in all operations. The maximum tumor diameter of the patients in the arterial staining group, the reverse staining group, and the positive staining group(M (IQR)) was 2.5 (2.4) cm, 3.0 (2.5) cm and 3.0(2.4) cm,respectively. There were no statistically significant differences in the maximum tumor diameter between the three groups (P=0.364). The minimum tumor margin was 1.1 (1.1) cm, 1.0 (1.0) cm, 1.1 (1.6) cm in the the arterial staining group, reverse staining group and the positive staining group, respectively. There was no significant difference in the margin among the three groups (P=0.878). (2) Operation conditions: the operation time of the arterial staining group, the negative staining group, and the positive portal staining group was (348±93)minutes,(277±112)minutes,and (295±116)minutes,respectively. There were no significant differences in operation time among the three groups (P=0.134). The intraoperative blood loss of the three groups was 80(150)ml,200(350)ml,and 100(150)ml,respectively. There was no statistically significant difference in intraoperative bleeding volume between the three groups(P=0.743). All cases were not transfused during the operation and were not converted to laparotomy. ALT in the arterial staining group was higher than in the negative staining group in the first two days after the operation ((559±398)IU/L307(257) IU/L, q=235.5,P=0.004;(611±389)IU/L(331±242) IU/L, q=265.2, P=0.002). There was only one case of a grade III complication (Clavien-Dindo grading system) postoperative complication in the negative and positive staining group of the portal vein, respectively. Tumor markers in all patients decreased to the normal range after 2 months of operation. Conclusion: Laparoscopic anatomical hepatectomy guided by ICG fluorescence through arterial staining and portal vein staining is safe and feasible for primary hepatocellular carcinoma treatment.

Objective:To compare the in vitro susceptibility of fluconazole-resistant Candida albicans strains from superficial and deep infections to 8 antifungal drugs, and to compare drug resistance mutations in these strains. Methods:According to the Clinical and Laboratory Standards Institute (CLSI) protocol M27-A4, 26 deep infection-derived and 33 superficial infection-derived drug-resistant Candida albicans strains were tested for in vitro susceptibility to 8 antifungal drugs (fluconazole, voriconazole, itraconazole, posaconazole, amphotericin B, fluorocytosine, terbinafine, and micafungin) alone or in combination. DNA was extracted from all drug-resistant strains, and mutations in 3 drug resistance genes, including ERG3, ERG11 and FUR1, were detected by PCR. Normally distributed measurement data with homogeneous variance were compared between two groups by using two-independent-sample t test, non-normally distributed measurement data with non-homogeneous variance were compared using Mann-Whitney U test, and enumeration data were compared using chi-square test. Results:The minimum inhibitory concentrations (MICs) of fluconazole, itraconazole, voriconazole, posaconazole and fluorocytosine all significantly differed between the superficial infection group and deep infection group (all P < 0.05) , while there was no significant difference in the MIC of amphotericin B or micafungin between the two groups (both P > 0.05) . The MIC of terbinafine was >64 μg/ml in 96.6% of the above strains, so could not be compared between groups. As combination drug susceptibility testing revealed, the combination of terbinafine with azoles (fluconazole, voriconazole, itraconazole or posaconazole) showed synergistic inhibitory effects against 15 Candida albicans strains (7 strains from deep infections, 8 strains from superficial infections) , with fractional inhibitory concentration (FIC) indices being 0.033 to 0.187; no marked synergistic effect was observed in the combinations between fluorocytosine and azoles, between fluorocytosine and amphotericin B, or between amphotericin B and fluconazole, with the FIC indices being 0.56 to 1.125. The missense mutation V351A in the ERG3 gene was identified in all the 33 (100%) superficial infection-derived strains, as well as in 13 (50%) deep infection-derived strains, and the mutation A353T in the ERG3 gene was identified in 4 (15%) deep infection-derived strains; as for the ERG11 gene, missense mutations identified in the superficial infection-derived strains included I437V (32 strains, 97%) , Y132H (23 strains, 70%) , T123I (16 strains, 48%) , K128T (6 strains, 18%) , D116E (5 strains, 15%) , A114S (4 strains, 12%) , E266D (2 strains, 6%) , G448E (2 strains, 6%) , and G465S (2 strains, 6%) , while missense mutations identified in the deep infection-derived strains included I437V (23 strains, 88%) , E266D (13 strains, 50%) , E260G (5 strains, 19%) , and V488I (4 strains, 15%) ; the missense mutation R101C in the FUR1 gene was identified in 11 (33%) superficial infection-derived strains, but not identified in deep infection-derived strains. Conclusion:The drug susceptibility and drug resistance mutations differed to some extent between superficial infection- and deep infection-derived fluconazole-resistant Candida albicans strains.

Objective To establish serum NGAL reference range of healthy populations in Xi'an Area.Methods 2 665 cases (aged 6 to 95 years old,male 1 370,female 1 295) of health-check people were collected from March 2014 to October 2016 in Medical Examination Center of Shaanxi Provincial People's Hospital,and 682 cases (aged 0 to 6 years old,male 356,female 326) were collected from preschool children of prevention.Serum NGAL concentration of them were analysed by immunoturbidimetry method with the Automatic Biochemical Analysis Assembly Line of Beckman-AU5800,and the detection data for statistical analysis.Then established the reference range of serum NGAL population of different age and different sex in Xi'an.Results The serum NGAL levels in healthy subjects showed a skewed distribution,which were preschool children under 6 years of age 37.66±23.12 ng/ml,6～15 years 39.25±25.34 ng/ml,16～49 years 46.68±27.06 ng/ml,and 50～ 69 years 57.82±29.13 ng/ml.Compared the first two with the latter,there was a significant difference (t=0.589,P＜ 0.05).The serum NGAL levels of over 70 years were 61.87 ± 32.64 ng/ml,and there was a significant difference between the ages of 15 and 49 and over 70 years (t=8.529,P＜0.01).At the same time,the serum NGAL was closely correlated with age (r=0.298,P＜0.01).But there was no significant difference in serum NGAL level between male and female (t=0.263～0.542,all P＞0.05).87ng/ml was the upper limit of the reference value for the age of 50 years.Conclusion The level of serum NGAL was related to age and increased with age,but not with gender.
