Berberine (BBR) is the main pharmacological active ingredient of Coptidis, which has hypoglycemic effect, but its clinical application is limited due to its poor oral bioavailability. Polyphenols, derived from cinnamon, are beneficial for type 2 diabetes mellitus (T2DM). The combination of both may have an additive effect. The aim of this study was to investigate the hypoglycemic effect and mechanism of combined medication in diabetic rats. The modeling rats were randomly divided into 5 groups (berberine group, cinnamon group, combined group, metformin group, diabetic control group) and normal control group. The animal experiments were approved by the Animal Ethics Committee (approval number: HMUIRB2022003). The subjects were given orally, and the control group was given equal volume solvent and body weight was measured weekly. Thirty days after administration, oral glucose tolerance test and insulin sensitivity test were performed, and fasting blood glucose (FBG), glycated serum protein (GSP), and serum insulin (INS) levels were detected; high-throughput sequencing technology was used to detect intestinal microbiota structure; real-time quantitative PCR (RT-qPCR) and Western blot were used to detect G protein-coupled receptor 5 (TGR5) and glucagon-like peptide-1 (GLP-1) expression levels. The results showed that, compared with the diabetic control group, the levels of FBG (

Objective:
To assess the efficacy and safety of combining traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), with Western medicine (WM), compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis (BCET-OP) by meta-analysis.
Methods:
Thirty-eight randomized controlled trials involving 2170 participants were analyzed. Eight databases were searched for articles published between inception and December 2023. Quality assessment was performed using the Risk of Bias 2 tool.
Results:
Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density (BMD) (P < .001, mean difference (MD) = 0.07, 95% confidence interval (CI): 0.06 to 0.08), lumbar vertebrae T-score (P = .0005, MD = 0.21, 95%CI: 0.09 to 0.33) and collum femoris BMD (P = .01, MD = 0.10, 95%CI: 0.02 to 0.19). No significant difference was observed between the groups in the collum femoris T-score and estradiol levels. Bone gla-protein levels were significantly increased in the TCM-WM group (P = .0002, MD = 0.52, 95%CI: 0.25 to 0.79). Beta-CrossLaps decreased significantly in the TCM-WM group (P = .0008, MD = −0.10, 95%CI: −0.16 to −0.04). No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase, in procollagen type I N-terminal propeptide, and in the Kupperman index. The visual analog score (VAS) was decreased in the TCM-WM group compared to the WM group (P < .001, MD = −1.40, 95%CI: −1.94 to −0.87). No significant difference in adverse events was observed between the two groups.
Conclusion
Combining CHM with WM in patients with BCET-OP significantly improved BMD, T-score, and certain bone turnover markers and reduced the VAS score, indicating potential benefits for bone health and related pain. Adverse event analysis revealed no differences between the groups, supporting the feasibility of the combination therapy. However, further research, particularly in diverse populations, is required.

As a new transdermal drug delivery system, microneedles can significantly improve skin permeability, enhance drug transdermal delivery, and demonstrate unique advantages in breaking stratum corneum barrier of skin. This feature enables microneedles to demonstrate enormous potential in delivering biotechnology drugs. The traditional delivery method for biotechnology drugs is mainly injection, which brings problems such as pain and skin redness to patients, leading to poor patient compliance. In addition, the production, transportation, and storage of biotechnology drugs require strict low-temperature conditions to maintain their activity and increase cost output. Microneedles, by contrast, have many benefits, providing new avenues and solutions for biomolecular delivery. Accordingly, this review introduced the microneedle drug delivery system for delivery biotechnology drugs, and summarized the research progress of microneedle systems in biotechnology drugs.

The paper is to establish an UPLC-MS/MS method for the simultaneous determination of 19 components in Microctis Folium from different production areas. The 50% methanol was used as extraction solvent. The Agilent ZORBAX SB C18 (150 mm × 2.1 mm, 1.8 μm) column was used; mobile phase was acetonitrile - 0.1% acetic acid with gradient elution, flow rate was 0.3 mL·min-1, colume temperature was 30 ℃, and the injection volume was 2 μL; electrospray ionizaton source was used and detected in negative ion mode. The results showed that the established UPLC-MS/MS method could well separate the 19 components, and the methodological investigation results of 19 components were good. By means of orthogonal partial least squares discriminant analysis (OPLS-DA), 28 batches of Microctis Folium samples from different production areas can be divided into three categories, Guangdong, Guangxi and Hainan are each classified into one category, and 10 signature compounds which affecting the quality differences of different production areas were screened out. The established method is accurate, reliable, sensitive and reproducible. It can provide a basis for the establishment of the quality standard of Microctis Folium, as well as for safety and quality research.

ObjectiveTo explore the interaction between bruceoside B and gut microbiota and the inhibitory activity of its metabolites on human lung cancer A549 cells, and to explore the value of bruceoside B in the treatment of non-small cell lung cancer(NSCLC). MethodBruceoside B was co-incubated with the human gut microbiota under anoxic conditions in vitro, and ultra high performance liquid chromatography-quadrupole-time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to analyze the metabolic transformation products. Cell counting kit-8(CCK-8) assay was performed to determine the effects of bruceoside B and its metabolites on the proliferation of human lung cancer A549 cells and the half inhibitory concentration(IC50) was calculated. Five healthy male rats were gavaged with bruceoside B(2 mg·kg-1) for 7 days after adaptive feeding. The feces of rats were collected before and after administration. 16S rRNA sequencing was used to assess gut microbiota. ResultBruceoside B was mainly metabolized to brusatol by human gut microbiota, the IC50 of bruceoside B and the conversion product to A549 cells were 1 755.50, 19.57 μmol·L-1, respectively, and the conversion product had a better activity at inhibiting A549 cells proliferation than bruceoside B. Additionally, The results of intestinal flora analysis showed no significant differences in α diversity and β diversity of gut microbiota after administration. In terms of species abundance, at the phylum level, bruceoside B decreased the relative abundance of Actinobacteriota and Proteobacteria, increased the relative abundance of Firmicutes, Patescibacteria and Cyanobacteria. At the genus level, bruceoside B decreased the relative abundance of Staphylococcus, Aerococcus and Psychrobacter, increased the relative abundance of Romboutsia, Lactobacillus, Clostridium sensu stricto 1, Norank-f-norank-o-Clostridia-UCG-014, Turicibacter, Allobaculum and Candidatus Saccharimonas. The results of functional prediction showed that the gut microbiota functional compositions were relatively stable. ConclusionBruceoside B can be deglycosylated by intestinal flora and converted into brusatol, with a significant increase in antitumor activity. The administration of bruceoside B will not cause significant changes in the structure and function of the intestinal flora, resulting in intestinal microecological balance disorders, and the administration appears to be beneficial to the intestinal flora of NSCLC patients.

Objective:To study the clinical manifestations, genetic profiles and treatment of Kagami-Ogata syndrome (KOS).Methods:A neonate admitted to our hospital was genetically diagnosed of KOS from amniocentesis sampling. The phenotype, genotype and treatment of the neonate were analyzed. Multiple databases were searched using key words including "Kagami-Ogata syndrome", "14q32 microdeletion syndrome", "coat-hanger ribs", "paternal uniparental disomy (pUPD)(14) " from the inception of the databases to Jan. 23th 2023. The clinical features, genotype and treatment of patients from the literature were summarized.Results:The neonate in our hospital was born at 30 weeks gestational age with a birth weight of 2 035 g. Prenatal ultrasound indicated overgrowth, bilateral fetal renal pelvis dilatation (FRPD), dilatation of intestines in lower abdomen, clenched hands with overlapping fingers and polyhydramnios. After birth, the neonate showed progressively worsening respiratory distress, distinct facial features (small jaw, short neck, flat nasal bridge, upward-facing nostrils, small and malformed ears with auricular deformity and narrow external auditory canals), bell-shaped thorax, diastasis recti and abnormal posture (overlapping fingers, clenched fists), as well as feeding difficulties, recurrent fever and dependence of respiratory support. Whole exome sequencing (WES) revealed a 268.2Kb deletion (101034306_101302541) in 14q32.2 region on both the neonate and the mother and the father was otherwise normal. The prognosis was poor and the parents refused further treatment. The neonate died at one month of age after two days of palliative care. A total of 36 articles were identified in the literature review, including 78 KOS cases with complete clinical data (a total of 79 cases adding our case).The primary clinical manifestations included distinctive facial and thoracic abnormalities (79/79, 100%), polyhydramnios (71/75, 94.7%), feeding difficulties (55/63, 87.3%), abdominal wall defects (57/72, 79.2%), joint contractures (39/70, 55.7%) and dependence of respiratory support (29/56, 51.8%). Long-term follow-up revealed 86.8% (59/68) experienced physical, movement and intellectual development delay, 39.7% (25/63) died or gave up treatments within five years. Genetic testing showed pUPD in 44 cases (55.7%), maternal deletions in 23 cases (29.1%), epimutations in 8 cases (10.1%) and unreported variations in 4 cases (5.1%).Conclusions:KOS is a genetic imprinting disorder affecting multiple organs. Prenatal screening can detect abnormalities such as polyhydramnios. Specific clinical signs, radiological findings and 14q32 gene analysis are helpful for the diagnosis of the disease.

Objective:To study the clinical characteristics and risk factors of nephrocalcinosis in preterm infants.Methods:From March 2021 to August 2021, all preterm infants admitted to NICU of our hospital were retrospectively analyzed. The infants were assigned into nephrocalcinosis group and non-nephrocalcinosis group according to urinary tract ultrasound. Clinical data including gestational age, birth weight(BW), nutritional support strategy and complications were reviewed.Results:A total of 40 preterm infants (<34 weeks) were enrolled. 9 cases were in the nephrocalcinosis group and 31 cases in the non-nephrocalcinosis group. The nephrocalcinosis group had lower BW[(1 167±214) g vs.(1 586±215) g], higher calcium [6.9 (5.1, 8.7) g vs.3.3 (2.1, 6.8) g] and vitamin D intake [3.2(2.5, 4.2)×10 4U vs.1.7(1.1, 3.2)×10 4U] during hospitalization. No significant differences existed between the two groups on the following items:blood calcium and phosphate, 25-hydroxyvitamin D, feeding strategy, time to reach full enteral feeding(TFF), furosemide dosage and respiratory support duration ( P>0.05). In the nephrocalcinosis group, the median age of diagnosing nephrocalcinosis was 40.0(30.0, 52.5)d after birth. 5 cases showed bilateral nephrocalcinosis. 5 cases in the nephrocalcinosis group received renal tubule function examination,4 cases had increased urine β2 microglobulin and 2 cases had increased urine α1 microglobulin. 7 cases had elevated urine calcium in the nephrocalcinosis group. Follow-up showed that nephrocalcinosis disappeared 3-9 months after birth. Conclusions:BW, total calcium and vitamin D intake are risk factors for nephrocalcinosis in preterm infants. Increased urine β2 microglobulin and calcium levels are common co-morbidities in preterm infants with nephrocalcinosis.
