Chronic prostatitis is a process of kidney deficiency and blood stasis mixed with various pathological factors involving the essence chamber,which is manifested as kidney deficiency and blood stasis.Based on the concept of the"brain-heart-kidney-es-sence chamber"axis of medication,Xiongji Formula is applied to the treatment of chronic prostatitis,due to its"simultaneous holistic and local action"and effects of tonifying the kidney yang and assisting the systemic yang,acting on the brain,heart and kidney as a whole,and meanwhile activating blood circulation,eliminating blood stasis and restoring the function of the essence chamber.This pa-per discusses the etiology and pathogenesis of chronic prostatitis with kidney deficiency and blood stasis in Chinese medicine,expounds the significance of"brain-heart-kidney-essence chamber"axis of medication,and explores the specific value and clinical application of Xiongji Formula.

Objective:To investigate the intervention effects and influencing factors of family management intervention on parents' disease management ability, family function of children with coronary artery lesions in Kawasaki disease.Methods:This was a quasi experimental study. Conveniently, 88 parents of children with Kawasaki disease coronary artery lesions from the Children's Hospital of Chongqing Medical University from March 2020 to June 2021 were selected for the study, and they were divided into the control group and the intervention group according to the order of the first consultation with 44 cases in each group. In the control group, conventional care and health education were used, while in the intervention group, a 6-month family management intervention was implemented on the basis of the control group. Family Management Measure (FaMM), Family Assessment Device (FAD) were used to assess the parents' disease management ability, family function before and after the intervention, respectively.Results:A total of 88 study subjects completed the pre-intervention survey in this study, and a total of 79 study subjects were surveyed when they returned to the hospital for review at the end of 6 months of intervention, including 40 in the intervention group and 39 in the control group, with a missed rate of 10.23% (9/88). There was no significant difference in the score of FAD, FaMM, Kawasaki disease knowledge questionnaire before the intervention between the two groups ( P>0.05). The scores of FAD in the intervention group was (21.58 ± 4.60) points, which was lower than that in the control group (24.62 ± 5.28) points, and the difference was statistically significant ( t=2.73, P <0.05). The scores of FaMM in the intervention group was (46.83 ± 6.02) points, which was higher than that in the control group (42.72 ± 6.09) points, and the differences was statistically significant ( t=-3.01, P <0.05). The age of the child, and whether the child was an only child were the influencing factors of the difference in disease management ability, and the difference in the family function of the parents of the child, respectively (all P<0.05). Conclusions:Family management intervention can improve the disease management ability of the parents of children with coronary artery lesion, improve family function. In the future, targeted interventions can be conducted according to different ages of children, and different family members' composition in order to obtain better intervention effects.

Danshen, the dried roots and rhizomes of Salvia miltiorrhiza Bunge (S. miltiorrhiza), is widely used in the treatment of cardiovascular and cerebrovascular diseases. Tanshinones, the bioactive compounds from Danshen, exhibit a wide spectrum of pharmacological properties, suggesting their potential for future therapeutic applications. Tanshinone biosynthesis is a complex process involving at least six P450 enzymes that have been identified and characterized, most of which belong to the CYP76 and CYP71 families. In this study, CYP81C16, a member of the CYP71 clan, was identified in S. miltiorrhiza. An in vitro assay revealed that it could catalyze the hydroxylation of four para-quinone-type tanshinones, namely neocryptotanshinone, deoxyneocryptotanshinone, and danshenxinkuns A and B. SmCYP81C16 emerged as a potential broad-spectrum oxidase targeting the C-18 position of para-quinone-type tanshinones with an impressive relative conversion rate exceeding 90%. Kinetic evaluations andin vivo assays underscored its highest affinity towards neocryptotanshinone among the tested substrates. The overexpression of SmCYP81C16 promoted the accumulation of (iso)tanshinone in hairy root lines. The characterization of SmCYP81C16 in this study accentuates its potential as a pivotal tool in the biotechnological production of tanshinones, either through microbial or plant metabolic engineering.

Sepsis is characterized by a severe and life-threatening host immune response to polymicrobial infection accompanied by organ dysfunction.Studies on the therapeutic effect and mechanism of immunomod-ulatory drugs on the sepsis-induced hyperinflammatory or immunosuppression states of various im-mune cells remain limited.This study aimed to investigate the protective effects and underlying mechanism of artesunate(ART)on the splenic microenvironment of cecal ligation and puncture-induced sepsis model mice using single-cell RNA sequencing(scRNA-seq)and experimental validations.The scRNA-seq analysis revealed that ART inhibited the activation of pro-inflammatory macrophages recruited during sepsis.ART could restore neutrophils'chemotaxis and immune function in the septic spleen.It inhibited the activation of T regulatory cells but promoted the cytotoxic function of natural killer cells during sepsis.ART also promoted the differentiation and activity of splenic B cells in mice with sepsis.These results indicated that ART could alleviate the inflammatory and/or immunosuppressive states of various immune cells involved in sepsis to balance the immune homeostasis within the host.Overall,this study provided a comprehensive investigation of the regulatory effect of ART on the splenic microenvironment in sepsis,thus contributing to the application of ART as adjunctive therapy for the clinical treatment of sepsis.

The potential medicinal value of Ma bamboo (Dendrocalamus latiflorus), one of the most popular and economically important bamboo species in China, has been underestimated. In the present study, we found that D. latiflorus leaf extract (DLE) reduced fasting blood glucose levels, body weight, and low-density lipoprotein cholesterol with low liver toxicity in db/db mice. In addition, gene expression profiling was performed and pathway enrichment analysis showed that DLE affected metabolic pathways. Importantly, DLE activated the AKT signaling pathway and reduced glucose production by downregulating glucose-6-phosphatase (G6PC) and phosphoenolpyruvate carboxykinase 1 (PCK1) expression. Moreover, network pharmacology analysis identified rutin as an active component in DLE through targeting insulin growth factor 1 receptor (IGF1R), an upstream signaling transducer of AKT. Due to its hypoglycemic effects and low toxicity, DLE may be considered an adjuvant treatment option for type 2 diabetes patients.

Objective To improve vibration resistance of conventional blood transportation kits and mitigate hemolysis during transportation.Methods The structure of a blood transportation kit was modified.We installed a suspension brac-kets within the kit,added buffer material between the brackets,and tested the vibration-suppressing effect compared with the conventional blood transportation kit.Results Rubber and plastic materials between brackets were added,and double membrane suspension brackets were installed.After 4 and 6 min of vibration,free hemoglobin(FHb)[(1559.7 ±1038.5) and(1886.2 ±1023.8)mg/L],lactic dehydrogenase levels[(135.3 ±67.7)and(195.7 ±123.6)U/L]and hemolysis rate[(0.35 ±0.34)%and(0.42 ±0.38)%]in the conventional transportation kit were significantly higher than in the vibration-suppressing kit.K+did not change significantly,and was comparable in both groups at each time point.After 4 and 6 min of vibration, FHb in the conventional transportation kit exceeded the standard.However, after 12 min of vibration,FHb[(560.1 ±342.3)mg/L]in the vibration-suppressing kit were within the standard range.No bacterial growth was detected in either group.Conclusion The vibration-suppressing kit under research shows a better 1986vibration-suppressing effect,which could improve blood support capability in case of emergency.

Objective To evaluate the clinical significance of direct trocar insertion using optical trocar in the establishment of the primary port during trans-peritoneal laparoscopic surgical procedures.Methods A prospective study was conducted by collecting the data of 120 patients who should be performed abdominal laparoscopic surgery from April 2015 to December 2015.The 120 patients were randomly divided into a research group and a control group.The research group consisted of 34 male patients and 26 female patients,mean age was (52.0 ± 11.9) years and mean BMI was (24.9 ± 2.9) kg/m2.In research group,patients were positioned laterally with the flank padded and elevated.A predetermined position was drawn prior to surgery between the umbilicus and lateral rectus abdominis,for the creation of the primary laparoscopic trocar port.The predetermined point was incised,and then the method of direct trocar insertion using the optical access trocar was used for establishment of the primary port.After this maneuver was completed the surgery continued as indicated.The control group consisted of 36 male patients and 24 female patients,whose mean age was (52.9 ± 11.4) years and mean BMI was (25.2 ± 2.4) kg/m2.This group underwent the traditional method of port construction by incision into the abdomen.The time of constructing the passage,leakage rate,bleeding rate,and injury rate of abdominal organs were compared.Results In research group,the time of building primary port was clearly shorter than that in control group (2.7min vs.15.9min,P ＜ 0.05),the leakage rate was also obviously reduced compared to that in control group (0 vs.30％,P ＜ 0.05).Neither groups observed any significant bleeding nor visceral organ damage throughout the study.Conclusion Direct trocar insertion using optical trocar to establish observation port is a highly efficient and safe method in trans-peritoneal laparoscopic operation,which should be research thoroughly in clinical practice.

OBJECTIVETo study the role of proximal nerve stimulation at Erb point in the early diagnosis of Guillain-Barré syndrome (GBS) in children.

METHODSThirty-two children who were diagnosed with GBS between October 2013 and December 2014 received neurophysiological examination. Thirty healthy children were used as controls. Compound muscle action potentials and distal motor latency of the median and ulnar nerves were determined and analyzed after nerve stimulation at the wrist, elbow, and Erb point in the two groups. Moreover, F-wave latency of the median nerve and H-reflex latency of the tibial nerve were measured and analyzed in the two groups.

RESULTSThe F-wave and H-reflex latencies were significantly longer in the patient group than in the control group (P<0.05). In thirty-two patients, the numbers of patients with abnormal amplitude, abnormal latency, and conduction block at Erb's point were 24 (75%), 22 (69%), and 20 (62%), respectively. The patient group had significantly lower amplitudes but significantly longer latencies of the ulnar and median nerves at Erb point than the control group (P<0.05). There were no significant differences in the amplitudes and latencies at the wrist and elbow between the two groups (P>0.05).

CONCLUSIONSThe nerve stimulation at Erb point holds promise as a routine examination for the early diagnosis of GBS.

OBJECTIVETo prepare and characterize rabbit polyclonal antibodies against Toxoplasma gondii vacuolar proton pyrophosphatase type I (TgVP1).

METHODS AND RESULTSTwo synthesized peptides TgVP1-1 and TgVP1-2 as the haptens were conjugated with KLH to immunize rabbits. Indirect ELISA showed that the titers of rabbit anti-TgVP1-1 polyclonal antibody and rabbit anti-TgVP1-2 polyclonal antibody reached 1:128 000. Western blotting results revealed that both purified polyclonal antibodies could specifically bind to a purified 85 kD T. gondii protein predicted as TgVP1. The protein detected by these two polyclonal antibodies was distributed in the cytoplasm of T. gondii tachyzoite, and this distribution pattern was consistent with that of acidocalcisome.

CONCLUSIONThe peptide-based method of antibody generation is efficient and the obtained TgVP1 polyclonal antibodies possess a high specificity to facilitate further study of T. gondii acidocalcisome and the diagnosis of toxoplasmosis.
