Matrine is an alkaloid compound isolated and extracted from the traditional Chinese medicinal plant Sophora flavescens, which has anti-tumor, anti-inflammatory, and anti-viral effects. However, its clinical application has been limited due to its low in vivo activity, short duration of efficacy, and significant toxic side effects. In response to this challenge，pharmaceutical experts modified the structure of Matrine to obtain derivatives that addressed its limitations. Currently, research on the anti-tumor effects of Matrine and its derivatives is more prevalent, while research in inflammatory-related diseases still needs further strengthening.The progress on the role and mechanism of Matrine and its derivatives in inflammatory diseases were summarized in this paper, which offered valuable insights for the development of therapeutic agents based on Matrine.

Objective To investigate the combined effect of berberine （BBR） and fluconazole （FLC） on FLC-tolerant Candida albicans in vitro. Methods The sensitivity of 8 strains of Candida albicans to FLC was assessed by determining their minimal inhibitory concentration （MIC） using broth microdilution method. FLC-tolerant strains were screened from FLC-sensitive strains by disk diffusion assay. The effect of BBR combined with FLC on FLC-tolerant Candida albicans was investigated by disk diffusion assay. Results All eight strains of Candida albicans exhibited sensitivity to FLC, with minimal inhibitory concentration （MIC₅₀） values below 0.5 μg/ml. Strains Y0109, 9821, 7879, 7654, and 9296 displayed colony growth in the inhibition zone after 48 h of constant temperature incubation, indicating FLC tolerance. When strains Y0109 and 9821 were subjected to a combination of BBR and FLC, the number of colonies within the inhibition zone decreased progressively with the increase of BBR concentration following a 48 h constant temperature culture. The inhibition zone became clear with the increasing of BBR concentration and increased with the increase of FLC loading, which showed a dose-dependent relationship. Conclusion The BBR combined with FLC demonstrated efficacy against FLC-tolerant strains.

Objective: To identify biomolecular markers closely related to the occurrence of kidney renal clear cell carcinoma (KIRC) and verify their expression levels in clinical samples. Methods: Stage Ⅰ KIRC mRNA sequencing data were obtained from The Cancer Genome Atlas (TCGA).Principal component analysis (PCA) was used for dimensionality reduction to screen differentially expressed genes (DEGs)，which then underwent GO and KEGG analyses.Weighted gene co-expression network analysis (WGCNA) was used to screen genes significantly related to KIRC，and a protein-protein interaction (PPI) network was constructed to screen hub genes.The diagnostic value of hub genes was evaluated with receiver operating characteristic (ROC) curve，and their prognostic value was analyzed using survival curve plots.The correlation between the mRNA expressions of hub genes and the pathological stages of KIRC was analyzed.Clinical samples of 20 patients with stage Ⅰ KIRC treated in our hospital were included，and the expressions of the hub genes in cancerous and adjacent tissues were detected with reverse transcription real-time quantitative polymerase chain reaction (RT-qPCR)，Western blotting，and enzyme-linked immunosorbent assay (ELISA). Results: A total of 8223 DEGs were screened out，including 4092 up-regulated ones and 4131 down-regulated ones.GO analysis showed that DEGs were related to bioadhesion，plasma membrane composition，and transporter activity.KEGG analysis showed that DEGs were related to pathways such as cell adhesion molecules，cytokine-cytokine receptor interactions，and interactions between viral proteins and cytokines and cytokine receptors.WGCNA analysis obtained 171 genes that were significantly related to stage Ⅰ KIRC.The hub gene，lymphocyte cytosolic protein 2 (LCP2)，screened out by the PPI network，was significantly related to stage Ⅰ KIRC.The area under the ROC curve was 0.96.The expression level was negatively correlated with the overall survival rate of patients.The expression of LCP2 was related to the stage and lymph node metastasis.Clinical verification showed that the mRNA and protein relative expressions of LCP2 in KIRC tissues were significantly higher than those in adjacent tissues (P<0.000 1). Conclusion: LCP2 is significantly up-regulated in stage Ⅰ KIRC tissues and can be used as a potential biomarker for the early diagnosis and treatment of KIRC.

Objective To observe the effects of ultrasound-guided serratus anterior plane block(SAPB)for pain relief in the acute phase of rib fractures and its impact on early rehabilitation.Methods This study included 160 patients from Taizhou Central Hospital with unilateral rib fractures undergoing conservative treatment.The patients were randomly divided into two groups,with 80 patients in each group.Group A received flurbiprofen alone for pain relief,while Group B received ultrasound-guided SAPB combined with flurbiprofen.Numerical rating scale(NRS)before treatment and at 1h,6h,12h,24h,and 48h after treatment,additional analgesic use,adverse reactions,functional recovery parameters(including vital capacity,peak expiratory flow,and walking distance),and hospital stay duration were recorded and compared between the two groups.Results The pain scores in Group B were significantly lower than those in Group A at 1h,6h,and 12h after treatment(P＜0.01),with no significant differences at 24h and 48h(P＞0.05).The use of additional analgesics and adverse reactions were significantly less in Group B compared to Group A(P＜0.01).Group B patients had significantly higher vital capacity,peak expiratory flow,and walking distance(P＜0.01).Additionally,the average hospital stay in Group B was significantly shorter than that in Group A(P＜0.01).Conclusion Ultrasound-guided SAPB combined with flurbiprofen is significantly more effective than flurbiprofen alone for treating rib fracture patients.SAPB provides more effective pain control,faster functional recovery,and has a high safety profile.

Purpose To explore the application of contrast-enhanced ultrasound in evaluating the local muscle microcirculation before and after acupuncture at Zusanli point in normal people.Materials and Methods A total of 72 healthy volunteers who visited the Department of Ultrasound,the Second Affiliated Hospital of Fujian Medical University from September 2018 to May 2020 were prospectively collected,all subjects performed ultrasound contrast before acupuncture,acupuncture with strongest deqi,and two hours after acupuncture to observe the blood flow perfusion of the microvessels in the tibialis anterior muscle.The pre-selected areas of interest the small arteries,muscle tissues and venules in the middle were analyzed to obtain the time-intensity curve and contrast transit time(CTTs)perfusion parameters.Needle sensation was evaluated using objective scoring criteria for acupuncture combined with moxibustion recipients.Gastrin,plasma gastrin,cholecystokinin,and secretin were measured in all subjects before acupuncture,when acupuncture had the strongest deqi,and two hours after acupuncture.Results ①CTTs of arterial-muscle,muscle-venous and arterial-venous of the tibialis anterior muscle at acupuncture with strongest deqi were significantly shorter than those at before acupuncture and two hours after acupuncture(all P<0.001),and there was no significant difference in CTTs before and after acupuncture and moxibustion(P>0.05);②when acupuncture deqi was strongest,serum gastrin,plasma prokinetics,cholecystokinin,and secretin were significantly increased compared with those before acupuncture and two hours after acupuncture,with statistically significant difference(all P<0.001),while there was no significant difference in these parameters between before acupuncture and two hours after acupuncture(P>0.05);③when acupuncture had the strongest deqi,there were positive correlations between gastrin,plasma prokinetic hormone,cholecystokinin,and secretin values and CTTs of arterial-muscle,muscle-venous,and arterial-venous(r=0.360-0.702,P<0.001).Conclusion Acupuncture of the Zusanli,when it gains the strongest deqi,can cause changes in the microcirculation around the skeletal muscle,leading to a significant shortening of CTTs,and also promotes the secretory function of the gastrointestinal tract.

Central precocious puberty (CPP) is an endocrine disease of children due to the early onset of hypothalamic-pituitary-gonadal axis function. This leads to increased secretion of gonadotropin release impulse, causing the development of internal and external genitalia and the presentation of secondary sex characteristics. Studies have found that the onset of CPP in children may be related to vitamin D deficiency. Vitamin D, affected by sunlight duration, acts on neurons and neurotransmitters in the hypothalamic-pituitary-gonadal axis, promotes obesity and affects the expression level of insulin-like growth factor-1, which are four factors involved in the occurrence and development of CPP. The overall effect of vitamin D combined with gonadotropin-releasing hormone analogues on CPP is significant. This article reviews the correlation between vitamin D deficiency and CPP, as well as the possible mechanism of action, in order to provide some theoretical basis for researchers.

Objective:To analyze the correlation between the muscle thickness (MT) and echo intensity (EI) of the medial head of gastrocnemius and muscle mass, strength and functional parameters, and to evaluate the diagnostic efficacy of MT and EI for decreased muscle mass.Methods:Fifty-two subjects who visited the Department of Ultrasound Medicine of the Second Affiliated Hospital of Fujian Medical University from March to December 2021 were collected.MT of the medial head of gastrocnemius was measured by two-dimensional ultrasound, and EI values in the region of interest were analyzed using Image J software. Twenty of the subjects were selected to assess the intra-observer and inter-observer agreements in measuring MT and EI values using the intraclass correlation coefficient (ICC) and Altman-Bland analysis was performed. The subjects were divided into healthy control group (30 cases) and decreased muscle mass group (22 cases) according to 2019 Asian Sarcopenia Working Group (AWGS) diagnostic criteria, the differences in MT and EI values between the two groups were compared, and the correlation between MT, EI values and muscle mass, strength, function were analyzed using Pearson correlation analysis. The diagnostic cutoff values of MT and EI values for decreased muscle mass were obtained using ROC curves, and the diagnostic efficacy was compared.Results:①The ICC of MT and EI in medial head of gastrocnemius detected by the same physician and different physicians were greater than 0.97, and the retest reliability was good. ②Compared with the healthy control group, the MT value in medial head of gastrocnemius decreased and the EI value increased in the decreased muscle mass group ( t=4.759, -3.789; all P<0.001). ③The MT value in medial head of gastrocnemius was positively correlated with appendicular skeletal muscle mass (ASM), appendicular skeletal muscle mass index (ASMI), lower limb skeletal muscle mass (LLSM), grip strength, and gait speed ( r=0.579, 0.568, 0.585, 0.495, 0.415; all P<0.001), of which, the correlation with LLSM was the best; ④EI in medial head of gastrocnemius was negatively correlated with ASM and ASMI, LLSM, grip strength, and gait speed, ( r=-0.583, -0.591, -0.590, -0.537, -0.455; all P<0.001), and among which the correlation with ASMI was the best. ⑤The medial head of gastrocnemius MT and EI were 14.33 mm and 58.85 for predicting decreased muscle mass, respectively, and there was no significant difference in the diagnostic performance of the two for decreased muscle mass ( Z=0.734 3, P>0.05). Conclusions:The MT and EI values of the medial head of gastrocnemius can accurately assess muscle mass and can be used in the evaluation of patients with decreased muscle mass.

ObjectiveTo determine the epidemiological characteristics of COVID-19 in Shaanxi Province. MethodsEpidemiological analysis was conducted on the confirmed cases of COVID-19 （n=245） from January 23rd， 2020 through February 21st， 2020 based on the official data announced by Shaanxi Province. The effects of local population migration， prevention and control measures on the epidemic were explored. ResultsAs of February 21st， 2020， a total of 245 COVID-19 cases had been notified in Shaanxi Province， with a cumulative incidence rate of 0.63 per 100 000， of which imported cases accounted for 47.34%. The high incidence was observed between January 31st and February 5th. Xi’an had the largest number of COVID-19 cases， followed by Ankang， Hanzhong and Xianyang， totally accounting for 81.20% of the cases in the province. In terms of social factors， daily morbidity was positively correlated with Baidu migration scale index 14 days before. On January 25th， the provincial health emergency response was launched， and on January 31st， it was further upgraded for quarantine. On February 20th， the provincial prevention and control system was implemented by classified areas. There were no emerging local cases after February 21st and no confirmed cases for 28th consecutive days as of March 19th. Local cases and close contacts were cleared to zero on March 27th. ConclusionThe COVID-19 epidemic in Shaanxi Province is mainly concentrated in Guanzhong area and southern Shaanxi， with a widespread pattern in all cities. The prevention and control measures have effectively contained the epidemic， with a declining incidence. However， quarantine of suspected cases and close contacts remains crucial for routine prevention and control strategy.

Objective:To compare the clinical effects of hip arthroplasty through direct anterior approach (DAA) in lateral decubitus in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia.Methods:The prospective study method was used to select the patients who needed hip arthroplasty in the Fourth Department of Orthopedics, the Second Affiliated Hospital of Harbin Medical University from January 2015 to December 2019. All of them were operated with lateral decubitus DAA. According to the inclusion criteria, they were divided into Kacshin-Beck disease hip osteoarthritis group (group A) and congenital acetabular dysplasia hip osteoarthritis group (group B). Hip Harris score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, visual analogue scale (VAS) score were conducted, and hip abduction angle and flexion angle were measured before surgery, 3, 14 days and 1, 3, and 12 months after surgery.Results:Nineteen and twenty-two patients were included in group A and group B, respectively. All patients successfully completed the surgery. There was no significant difference in Harris score between the two groups before surgery, 3, 14 days, and 1, 12 months after surgery ( P > 0.05). There were no significant differences in WOMAC score, VAS score, hip abduction angle and hip flexion angle between the two groups before surgery and each time point after surgery ( P > 0.05). In the same group, there were significant differences in Harris score, WOMAC score, VAS score, hip abduction angle and hip flexion angle at different time points ( P < 0.001). All postoperative indicators were significantly improved compared with those before surgery. Conclusions:There is no significant difference in the clinical effects of hip arthroplasty through lateral decubitus DAA in the treatment of hip osteoarthritis caused by Kaschin-Beck disease and congenital acetabular dysplasia. This surgical method has good therapeutic effect on both types of hip osteoarthritis.
