Objective:To analyze the medication law of Professor Liu Guangzhen in the treatment of diabetic nephropathy (DN) with qi-yin deficiency and blood stasis syndrome using data mining methods.Methods:From March 2023 to April 2024, the TCM outpatient prescriptions used by Professor Liu to treat DN with qi-yin deficiency and blood stasis syndrome were collected. The database was established by Excel 2019, and the property, taste, meridian, and use frequency of drugs were analyzed through the TCM inheritance assistance system V2.5. The Apriori algorithm in IBM SPSS Modeler 18.0 was used to analyze the association rules and draw the network diagram of high-frequency drugs, and the two-step hidden tree analysis algorithm (LTM-EAST) in the Lantern 5.0 was used to establish the hidden structure model of high-frequency Chinese materia medica. The obtained hidden variables were clustered and interpreted comprehensively, and scored by Bayesian information measure (BIC).Results:A total of 314 prescriptions were included, involving 182 kinds of Chinese materia medica, with a total frequency of 9 242 times. High frequency Chinese materia medica included Astragali Radix, Saposheikovize Radix, Atractylodis Macrocephalae Rhizoma fried with wheat bran, Litchi Semen, Hedyotis diffusa willd, Benincasae Exocarpium, Mori Folium, etc. The medicinal property was mainly warm, the tastes were mainly sweet, bitter and pungent, and the meridian tropism was mainly spleen, stomach, liver and kidney meridians. The efficacy classification was mainly tonic drugs, heat-clearing drugs, water-clearing and dampness-percolating drugs, and blood circulation-activating drugs. There were 150 association rules of high-frequency Chinese materia medica, including Astragali Radix-Saposheikovize Radix, Atractylodis Macrocephalae Rhizoma fried with wheat bran-Hedyotis diffusa willd, Saposheikovize Radix-Benincasae Exocarpium, etc. A total of 15 hidden variables, 30 hidden classes and 5 comprehensive clustering models were obtained by hidden structure model analysis.Conclusions:Professor Liu's treatment of DN withqi-yin deficiency and blood stasis syndrome is mainly based on tonifying qi and yin, tonifying spleen and kidney, removing dampness and turbidity and removing blood stasis. According to different conditions, the focus of medication has changed.

Objective To investigate the expression of YWHAQ protein in gastric adenocarcinoma tissues and its correlation with clinical pathological features and prognosis. Methods A total of 127 patients with gastric cancer who underwent radical surgery were enrolled. Clinical data and postoperative cancer tissue samples were collected from the patients. Immunohistochemistry was used to detect the protein expression of YWHAQ in gastric adenocarcinoma tissues. The relationship between YWHAQ expression and clinical pathological features and prognosis was analyzed. Bioinformatics prediction was performed to identify potential pathways regulated by YWHAQ in gastric adenocarcinoma. A protein-protein interaction network for YWHAQ was constructed using the STRING database. Results YWHAQ gene expression was significantly higher in gastric adenocarcinoma tissues than in normal tissues (P<0.05). The expression level of the YWHAQ protein was significantly correlated with age, tumor invasion depth, lymph node metastasis, and tumor stage (P<0.05). Kaplan-Meier survival analysis showed that patients with high YWHAQ expression had significantly poorer long-term survival than those with low expression (P<0.0001). Cox regression analysis revealed that high YWHAQ expression and distant metastasis were independent risk factors for gastric cancer (HR>1, P<0.05). Enrichment analysis indicated that YWHAQ positively regulated processes such as cell cycle, angiogenesis, and DNA damage repair. Conclusion YWHAQ is highly expressed in gastric adenocarcinoma tissues and may be associated with the occurrence, invasion, and metastasis of gastric adenocarcinoma. High YWHAQ expression and distant metastasis are independent risk factors for the prognosis of gastric adenocarcinoma patients.

In the earliest existing pharmacological monograph in China,Shennong Bencao Jing,there is a record of a parasitic plant known as"desert ginseng"——Cistanche deserticola.It exerts beneficial effects on the function of the heart,kidney,spleen,and lung.As research into its pharmacological properties has progressed,the active components of Cistanche deserticola also have shown promise for treating intestinal disorders.Due to the complex pathological mechanisms of sepsis,which often accompany multiple organ dysfunction,aligns closely with the multi-target pharmacological characteristics of Cistanche deserticola's.Furthermore,because Cistanche deserticola is both edible and medicinal,and exhibits a wide therapeutic window,it has a natural advantage in the clinical transformation and application after drug development.Currently,to expand its medicinal range,a review of the main active components of Cistanche deserticola and their related pharmacological effects is conducted,and combined with the specific characteristics of intestinal injury in sepsis,the potential value of Cistanche deserticola in intestinal barrier protection,microbial coordination,and intestinal motility regulation is further elaborated,providing new ideas and a theoretical basis for the application of Cistanche deserticola in sepsis-induced intestinal injury.

Objective:To analyze the genetic characteristics of hemagglutinin（HA）and neuraminidase（NA）of influenza A（H1N1）pdm09 viruses in Kunming during the 2022-2023 influenza season.Methods:A total of 15 strains of A（H1N1）pdm09 influenza virus isolated from sentinel hospital surveillance and from outbreaks from April 2022 to March 2023 in Kunming were chosen for sequencing. The genetic analysis，which included sequence alignment，homology analysis，construction of phylogenetic tree and amino-acid mutations analysis，was carried out using MAFFT version 7，MegAlign and MEGA 11.Results:Fourteen strains isolated during the 2022-2023 influenza season in Kunming belong to clade 6B.1A.5a.2a，and A/Kunming/284/2023 belonged to clade 6B.1A.5a.2a.1. They all diverged from the northern hemisphere vaccine strain A/Wisconsin/588/2019 in clade 6B.1A.5a.2 recommended by WHO during the 2022-2023 influenza season. Comparing with the HA of the vaccine strain：A186T and Q189E，which might cause the reduction of vaccine protection，were identified in Sb of 14 strains；P137S，K142R in Ca and A186T，Q189E in Sb were identified in A/Kunming/284/2023 and two strains isolated from Thailand. The four mutations at tow antigenic sites identified immune escape at the molecular level. Q189E in the 190-helix and E224A in the 220-loop，which might change the pathogenicity of A（H1N1）pdm09 viruses，were identified in 15 strains. Comparing with NA of the vaccine strain：S200N in 14 strains and S339L in 1 strain were identified in antigenic sites. The two mutations might reduce the protection of antibodies induced by NA.Conclusion:Strengthening influenza surveillance and timely detecting new variants in Kunming contributes to preventing the importation of foreign strains and issuing early warnings for influenza outbreaks.

Gastrointestinal polyposis syndromes are primarily characterized by multiple polyps in the gastrointestinal tract, with their pathogenic mechanisms largely related to genetic factors and involving multiple signaling pathways. Adenomatous polyposis syndromes are mainly associated with APC gene variants, while some cases may arise from MUTYH gene variants. Peutz-Jeghers syndrome is primarily linked to STK11 gene variants. Juvenile polyposis syndrome is mainly associated with variants in the SMAD4 and BMPR1A genes. PTEN hamartoma tumor syndrome is predominantly caused by PTEN gene variants. Hereditary mixed polyposis syndrome is primarily related to variants of the GREM1 and BMPR1A genes. This article systematically summarizes the advance in genetics research on Gastrointestinal polyposis syndromes to enhance clinicians′ understanding of these diseases and improve their diagnostic and therapeutic approaches.

Objective:To explore the advantages of robotic-arm assisted total hip arthroplasty (rTHA) in acetabular component positioning and lower limb length assessment in patients with severe pelvic coronal tilt.Methods:A retrospective analysis was conducted on the data of 122 patients with unilateral end-stage hip disease and coronal pelvic tilt angle >3° who underwent total hip arthroplasty (THA) at the First Medical Center of PLA General Hospital from June 2022 to December 2023. Among them, 44 patients underwent rTHA, and 78 underwent manual THA (mTHA). The rTHA group included 18 males and 26 females, with an average age of 60.5±9.3 years; the mTHA group included 41 males and 37 females, with an average age of 58.5±8.4 years. Compare the differences in the anteversion angle, abduction angle, pelvic tilt angle, leg length discrepancy (LLD) of the acetabular prosthesis, and the proportions of patients with LLD>0.5 cm and >1 cm between the two groups of patients after surgery. Calculate the proportion of outlier rates of acetabular abduction angle (<30° or >45°), and proportions within Callanan's safe zone. The early efficacy of the hip joint was evaluated by using the modified Harris score and joint range of motion.Results:All patients were followed up for 6 to 12 months, with an average of 8 months. All the surgical incisions of the patients achieved primary healing. Postoperative comparisons showed no statistically significant differences in acetabular abduction angle (39.5°±3.3° vs. 38.4°±7.3°) or anteversion angle (20.7°±1.6° vs. 19.7°±1.6°) between rTHA and mTHA groups ( P>0.05). However, pelvic tilt angle [2.5° (1.1°, 3.6°) vs. 3.5° (2.3°, 5.9°)] showed a statistically significant difference ( U=4.371, P=0.008). The rTHA group exhibited smaller absolute LLD [0.2 (0.1, 0.4) cm vs. 0.5 (0.2, 0.5) cm] and lower proportions of LLD >0.5 cm [14% (6/44) vs. 49% (38/78)] and >1 cm [2% (1/44) vs. 18% (14/78)], with statistical significance ( P<0.05). The rTHA group had a lower outlier rate for acetabular abduction angle (<30°or >45°) compared to the mTHA group [2% (1/44) vs. 33% (26/78)], with statistical significance (χ 2=10.388, P<0.001). Taking the Callanan safety zone as the standard, the proportion of acetabular cups within the safe zone was significantly higher in the rTHA group (98%, 43/44) compared to the mTHA group (67%, 52/78), with a statistically significant difference (χ 2=13.998, P<0.001). The modified Harris score and hip joint range of motion in the mTHA group increased from 47.6±6.6 points and 83° (73°, 88°) before the operation to 83.5±11.2 points and 118° (110°, 122°) at the last follow-up, respectively. The rTHA group increased from 46.5±9.2 points and 79° (71°, 90°) before the operation to 85.0±12.5 points and 124° (116°, 130°) at the last follow-up. The differences in the modified Harris score and hip joint range of motion between the two groups before the operation and at the last follow-up were statistically significant ( P<0.05). However, there was no statistically significant difference between the groups at the last follow-up ( P>0.05). No THA-related complications occurred during follow-up period. Conclusion:For patients with end-stage hip joint diseases with coronal tilt exceeding 3°, robotic-assisted technology significantly improves the accuracy of acetabular component placement during THA and offers better control of postoperative LLD.

Objective:To analyze the genetic characteristics of the prevalent strains of Varicella-Zoster virus (VZV) in the population of Dali, Yunnan, and to understand its evolutionary status in the population of Dali.Methods:Herpes fluid and 163 sera were collected from 249 patients clinically suspected to have varicella or herpes zoster in the Department of Dermatology of the Second People′s Hospital of Dali city, Yunnan province, China, from 2023 to 2024. The levels of VZV-specific IgG and IgM antibodies in serum were detected using enzyme-linked immunoassay. Viral DNA was extracted from the herpes fluid, and the cycle threshold ( Ct) of the samples was detected using quantitative real-time polymerase chain reaction (qPCR), and some samples with Ct ≦ 22 were selected for sequencing by next-generation sequencing technology (next-generation sequencing). Next-generation sequencing (NGS) was used to obtain 90 whole genome sequences of VZV, and the sequencing result were compared with the sequences of reference strains for multiple sequence comparison and evolutionary analysis. Snapgene was used to translate the nucleotides into amino acids, and the result were compared with the amino acid sequences of the reference strain. Results:Of the 90 VZV whole-genome sequences, one whole-genome sequence was from an adult varicella patient, and the remaining 89 whole-genome sequences were from herpes zoster patients. The serum-specific IgG antibody positivity rate was 99.4%, and the IgM antibody positivity rate was 52.8%. The result of both single nucleotide polymorphism (SNPs) site typing and genome-wide phylogenetic tree analysis showed that 83 of the 90 VZV whole-genome sequences in this study were on the same branch as Clade 2, and 7 VZV whole-genome sequences were on the branch of Clade 9.Conclusions:The main endemic branch in Dali region in 2023-2024 was Clade 2, with the emergence of Clade 9 branch; there were amino acid mutations in the proteins encoded by ORF22 and ORF68 in 83 VZV whole genome sequences of Clade 2 branch, and the mutations did not cause significant changes to the protein structure.
