Analyzing the spatial distribution pattern and formation factors of medicinal plant resources can provide a scientific basis for the protection and development of traditional Chinese medicine(TCM) resources. This study is based on the survey data of medicinal plant resources in 104 county-level administrative regions of Anhui province in the Fourth National Survey of TCM Resources. The global spatial autocorrelation analysis, trend surface analysis, local spatial autocorrelation analysis, hotspot analysis, and a geodetector were employed to analyze the spatial distribution pattern of medicinal plant richness, and its relationship with natural factors was explored. The results can provide a basis for the formulation of development strategies such as the protection and utilization of TCM resources, as well as offer a scientific foundation for the establishment of regional planning schemes for TCM resources in Anhui province. The results indicated that the richness of medicinal plant resources in Anhui province had significant spatial heterogeneity, exhibiting highly clustered distribution characteristics. Cold spots and hot spots presented clustered distribution patterns, with cold spots mostly located north of the Huaihe River and hot spots south of the Yangtze River. Overall, the distribution of medicinal plant resources in Anhui province showed an overall trend of high in the south and low in the north, which was consistent with the overall geomorphic trend of this province. In addition, natural factors such as altitude, precipitation, and vegetation type played an important role in the diversity and spatial distribution pattern formation of medicinal plant resources. The extraction and analysis of the spatial distribution characteristics of natural factors in cold and hot spot regions discovered that the heterogeneity of eco-environments constituted a fundamental condition for the formation of species diversity.

PURPOSE: The rate of complications among patients undergoing surgery has increased due to infection with SARS-CoV-2 and other variants of concern. However, Omicron has shown decreased pathogenicity, raising questions about the risk of postoperative complications among patients who are infected with this variant. This study aimed to investigate complications and related factors among patients with recent Omicron infection prior to undergoing orthopedic surgery. METHODS: A historical control study was conducted. Data were collected from all patients who underwent surgery during 2 distinct periods: (1) between Dec 12, 2022 and Jan 31, 2023 (COVID-19 positive group), (2) between Dec 12, 2021 and Jan 31, 2022 (COVID-19 negative control group). The patients were at least 18 years old. Patients who received conservative treatment after admission or had high-risk diseases or special circumstances (use of anticoagulants before surgery) were excluded from the study. The study outcomes were the total complication rate and related factors. Binary logistic regression analysis was used to identify related factors, and odds ratio (OR) and 95% confidence interval (CI) were calculated to assess the impact of COVID-19 infection on complications. RESULTS: In the analysis, a total of 847 patients who underwent surgery were included, with 275 of these patients testing positive for COVID-19 and 572 testing negative. The COVID-19-positive group had a significantly higher rate of total complications (11.27%) than the control group (4.90%, p < 0.001). After adjusting for relevant factors, the OR was 3.08 (95% CI: 1.45-6.53). Patients who were diagnosed with COVID-19 at 3-4 weeks (OR = 0.20 (95% CI: 0.06-0.59), p = 0.005), 5-6 weeks (OR = 0.16 (95% CI: 0.04-0.59), p = 0.010), or ≥7 weeks (OR = 0.26 (95% CI: 0.06-1.02), p = 0.069) prior to surgery had a lower risk of complications than those who were diagnosed at 0-2 weeks prior to surgery. Seven factors (age, indications for surgery, time of operation, time of COVID-19 diagnosis prior to surgery, C-reactive protein levels, alanine transaminase levels, and aspartate aminotransferase levels) were found to be associated with complications; thus, these factors were used to create a nomogram. CONCLUSION Omicron continues to be a significant factor in the incidence of postoperative complications among patients undergoing orthopedic surgery. By identifying the factors associated with these complications, we can determine the optimal surgical timing, provide more accurate prognostic information, and offer appropriate consultation for orthopedic surgery patients who have been infected with Omicron.

OBJECTIVES: To investigate the molecular epidemiology of children with phenylketonuria (PKU) in Gansu, China, providing foundational data for intervention strategies. METHODS: A retrospective analysis was conducted on 1 159 PKU families who attended Gansu Provincial Maternity and Child Care Hospital from January 2012 to December 2024. Sanger sequencing, multiplex ligation-dependent probe amplification, whole exome sequencing, and deep intronic variant analysis were used to analyze the PAH gene. RESULTS: For the 1 159 children with PKU, 2 295 variants were identified in 2 318 alleles, resulting in a detection rate of 99.01%. The detection rates were 100% (914/914) in 457 classic PKU families, 99.45% (907/912) in 456 mild PKU families, and 96.34% (474/492) in 246 mild hyperphenylalaninemia families. The 2 295 variants detected comprised 208 distinct mutation types, among which c.728G>A (14.95%, 343/2 295) had the highest frequency, followed by c.611A>G (4.88%, 112/2 295) and c.721C>T (4.79%, 110/2 295). The cumulative frequency of the top 23 hotspot variants reached 70.28% (1 613/2 295), and most variant alleles were detected in exon 7 (29.19%, 670/2 295). CONCLUSIONS Deep intronic variant analysis of the PAH gene can improve the genetic diagnostic rate of PKU. The development of targeted detection kits for PAH hotspot variants may enable precision screening programs and enhance preventive strategies for PKU.

OBJECTIVES: To evaluate whether adding Fuzheng Jiedu Xiaoji (FZJDXJ) therapy improves survival in advanced hepatitis B virus-related HCC (HBV-HCC) patients. METHODS: This prospective, randomized controlled study was performed at a major academic medical center in Beijing, China from October 2020 to October 2022. Eligible patients with advanced HBV-HCC were randomly divided equally (1:1) to receive either the combination of FZJDXJ and conventional Western medical therapy (63 cases, FZJDXJ group) or solely Western medicine (66 cases, control group). The study endpoints consisted of overall survival (OS) as the primary outcome, with progression-free survival (PFS), disease control rate (DCR), and adverse events (AEs) as secondary measures. RESULTS: The median OS was significantly prolonged in the FZJDXJ group at 8.9 months (95% CI: 6.0-11.9) vs. 4.4 months (95% CI: 3.2-7.3) in the control group (P<0.05). The hazard ratio for mortality in the FZJDXJ group was 0.59 (95% CI: 0.40-0.89), suggesting a 41% lower risk of death compared to the control group. The results revealed that patients receiving FZJDXJ therapy achieved a PFS of 5.1 months (95% CI: 4.1 to 7.2 months), compared to only 2.9 months (95% CI: 2.0 to 4.6 months) in the control group (P<0.05). Additionally, DCR was significantly elevated in the FZJDXJ group (20.6%) compared to the control group (10.6%, P<0.05). Subgroup analysis demonstrated that FZJDXJ significantly improved OS in patients with alpha-fetoprotein levels <400 ng/mL, age <60 years, Barcelona Clinic Liver Cancer (BCLC) stage C, and compensated liver function (Child-Pugh A and B, P<0.05). Multivariate analysis revealed that FZJDXJ therapy acted as an independent factor protecting against mortality within 1 year. Gastrointestinal symptoms are rare side effects, and no fatalities associated with the treatment were reported. CONCLUSION This randomized controlled trial demonstrated that FZJDXJ combined Western conventional therapy significantly improves OS and PFS in patients with advanced HBV-HCC.

OBJECTIVE: Huachansu injection (HCSI), a promising anti-cancer Chinese medicine injection, has been reported to have the potential for reducing the toxicity of chemotherapy and improving the quality of life for colorectal cancer (CRC) patients. The objective of this study is to explore the synergistic and detoxifying effects of HCSI when used in combination with irinotecan (CPT-11). METHODS: To investigate the effect of HCSI on anti-CRC efficacy and intestinal toxicity of CPT-11, we measured changes in the biological behavior of LoVo cells in vitro, and anti-tumor effects in LoVo cell xenograft nude mice models in vivo. Meanwhile, the effect of HCSI on intestinal toxicity and the uridine diphosphate-glucuronosyltransferase 1A1 (UGT1A1) expression was investigated in the CPT-11-induced colitis mouse model. Subsequently, we measured the effect of HCSI and its 13 constituent bufadienolides on the expression of UGT1A1 and organic anion transporting polypeptides 1B3 (OATP1B3) in HepG2 cells. RESULTS: The combination index (CI) results showed that the combination of HCSI and CPT-11 exhibited a synergistic effect (CI < 1), which significantly suppressing the LoVo cell migration, enhancing G2/M and S phase arrest, and inhibiting tumor growth in vivo. Additionally, the damage to intestinal tissues was attenuated by HCSI in CPT-11-induced colitis model, while the increased expression of UGT1A1 in HepG2 cells and in mouse was observed. CONCLUSION The co-therapy with HCSI alleviated the intestinal toxicity induced by CPT-11 and exerted an enhanced anti-CRC effect. The detoxifying mechanism may be related to the increased expression of UGT1A1 and OATP1B3 by HCSI and its bufadienolides components. The findings of this study may serve as a theoretical insights and strategies to improve CRC patient outcomes.

Objective:To investigate the early clinical efficacy of arthroscopic suture and transoral tunnel Versalok anchor fixation in the treatment of acute posterior cruciate ligament (PCL) femoral avulsion fractures in adults.Methods:A retrospective study was conducted to analyze the clinical data of 4 patients with acute PCL femoral insertion avulsion fracture who had been treated at Sports Medicine Center, Xi'an Honghui Hospital from January 2019 to June 2023. They were 1 male aged 49 years old and 3 females aged 39, 44, and 59 years old. Their time from injury to surgery was 3, 4, 9, and 12 days, respectively. All patients underwent arthroscopic suturing of the PCL femoral avulsion ligament junction. The sutures were pulled towards the medial femoral condyle through a bone tunnel created in the area of the medial femoral condyle ligament footprint and fixated with the Versalok anchor. Magnetic resonance imaging (MRI) was performed at 6 months postoperatively to assess union of the avulsion fracture and PCL continuity. The postoperative active knee flexion and extension, ligament tension, knee stability and knee functional recovery were recorded at the final follow-up.Results:One female patient sprained her knee while walking 6 months after surgery and then gradually developed knee pain and instability symptoms with a positive posterior drawer test (grade Ⅲ). She underwent PCL ligament reconstruction 7 months after surgery so that her follow-up was terminated. The remaining 3 patients were followed for 6, 12 and 13 months, respectively. Their active knee extension and flexion activities were comparable to those on the unaffected side and within the normal range at the last follow-up. Two patients had a negative posterior drawer test and 1 patient a positive posterior drawer test (grade I) but no symptoms of knee instability.Conclusion:Arthroscopic suture and bone tunnel Versalok anchor fixation technique in the treatment of acute femoral PCL avulsion fractures in adults is feasible and effective.

Objective:To investigate the early clinical efficacy of arthroscopic suture half-tie combined with Versalok anchor fixation in the treatment of avulsion fracture of the tibial insertion of anterior cruciate ligament (ACL) in adults.Methods:A retrospective study was conducted to analyze the clinical data of the 26 adult patients with avulsion fracture of the ACL tibial insertion who had been treated by arthroscopic suture half-tie combined with Versalok anchor fixation between June 2020 and December 2022 at Sports Medicine Center, Honghui Hospital, Xi'an Jiaotong University. This cohort consisted of 12 males and 14 females with an age of (26.6±7.5) years. According to the Meyers-McKeever classification, there were 9 cases of type Ⅱ, 12 cases of type Ⅲ, and 3 cases of type Ⅳ. The time from injury to surgery was (9.3±6.8) days. Follow-up evaluations were conducted at postoperative 3 days, 3 months, and 12 months, including imaging assessments for fracture healing, clinical examinations of knee flexion and extension, anterior drawer and Lachman tests to assess the ACL tension. At the last follow-up, KT-2000 test was performed to quantify ACL laxity, and visual analogue scale (VAS) and Lysholm knee score were used to assess postoperative pain and functional recovery.Results:Primary wound healing was achieved in all the 26 patients. One patient required ACL reconstruction due to laxity and mild extension limitation at postoperative 6 months. The other 25 patients were followed for (15.4±3.2) months. At postoperative 12 months, X-rays showed good bone healing at the fracture site of the tibial intercondylar eminence, and both the Lachman and anterior drawer tests were negative. At postoperative 3 months and the last follow-up, the active knee extension and flexion were 128.8° (121.2°, 138.3°) and 52.7° (38.2°, 63.2°), respectively, significantly better than the preoperative value [52.7° (38.2°, 63.2°)] ( P<0.05), and the KT-2000 test showed that the disparity between the affected and healthy sides were 2.5 (1.2, 4.2) mm and 1.2 (0.8, 3.4) mm, respectively, significantly smaller than the preoperative value [7.1 (5.2, 11.2) mm] ( P<0.05). At postoperative 3 and 12 months, the VAS pain scores were significantly decreased and the knee Lysholm scores were significantly improved compared with the preoperative values ( P<0.05). Conclusion:In the treatment of avulsion fracture of the ACL tibial insertion in adults, arthroscopic suture half-tie combined with Versalok anchor fixation is a minimally invasive, reliable, and straightforward technique, leading to excellent early clinical outcomes.

Objective To evaluate the efficacy and safety of transcatheter aortic valve implantation(TAVI)for the treatment of primary aortic valve regurgitation(NAVR)and to compare the difference in the choice of prosthetic valve size and the difference in complications with aortic stenosis(AS).Methods According to the definition of Valve Academic Research Consortium(VARC-3),143 patients with NAVR/AS treated with TAVI and patients with NAVR treated with surgical aortic valve replacement(SAVR)at Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology,China,from March 2019 to September 2024 were selected,and clinical data on baseline,perioperative,and primary endpoint events were were retrospectively collected and compared.Results Forty-three patients with NAVR were treated with TAVI,with a device success rate of 86.0％and a surgical success rate of 95.3％.Subgroup comparisons:(1)NAVR-TAVI group than NAVR-SAVR group:patients in the TAVI group had a significantly shorter operative time than those in the SAVR group(P＜0.001);complete left bundle branch block was more likely to occur after TAVI(P=0.042),and complete right bundle branch block was more likely to occur after SAVR(P=0.044).SAVR postoperatively The incidence of congestive heart failure was higher(P=0.013),and the mortality rate was significantly higher in the SAVR group than in the TAVI group(P=0.019).(2)NAVR-TAVI group than AS-TAVI group:the differences in access selection,THV size[28(22,34)mm vs.24(22,32)mm,P=0.044]and proportion of THV overdiameter[14％(7％,20％)vs.7％(3％,11％),P＜0.001]were statistically significant.patients in AS and NAVR groups had 1 case of permanent pacing after TAVI treatment.In the AS and NAVR groups,there was 1 case of permanent pacemaker implantation after TAVI.2 patients in the AS group were converted to surgical treatment,and 6 patients died.Conclusions The use of"off-label"(transfemoral)and"on-label"(transapical)TAVI devices(both from domestic sources)is safer than SAVR for the treatment of NAVR,especially in elderly and high-risk patients.Compared with patients with AS treated with TAVI,larger diameter annulas are usually selected for NAVR,with higher rates of valve migration,but overall safety and efficacy are comparable to AS.

Objective By observing and measuring the relevant data of the buccal branch of the facial nerve,the parotid duct and the facial artery,the positional relationship among the three was analyzed to avoid accidental injury to the buccal branch of the facial nerve and the parotid duct when ligaturing the facial artery during the operation.Methods Forty adult head and neck specimens were dissected to observe the relationship between the buccal branch of the facial nerve and the parotid duct,the course and positional relationship of the facial artery,and the relationship between the buccal branch of the facial nerve and the peripheral vascular network.The relevant diameters were measured with a vernier caliper.Results The buccal branch of the facial nerve was divided into the superior buccal branch and the inferior buccal branch,and there was no direct anastomosis or connecting fiber between the buccal branch of the facial nerve and the parotid duct.The superior buccal branch was relatively thick,and it has a relatively constant position,which was parallel to the parotid duct.The position of the inferior buccal branch was not constant and it ran on or slightly above the plane of angulus oris.The superior buccal branch was located(10.76±5.54)mm from the parotid duct,while the inferior buccal branch was positioned(6.84±4.06)mm away from the parotid duct.The course of the main trunk of the facial artery was relatively fixed.Moreover,if the branch of the facial artery was missing,other branches of the facial artery would extend to replace the missing branch artery.The main trunk of the facial artery had a diameter of(2.34±0.83)mm,and its branches formed anastomoses with the buccal branch of the maxillary artery,creating a vascular network in the parotid and buccal regions.There was a vascular network around the buccal branch of the facial nerve,which was mostly small branches of the facial artery and the superficial temporal artery.Conclusion The buccal branch of the facial nerve exhibits a consistent anatomic relationship with the parotid duct and the facial artery.During the ligation of the facial artery,the parotid duct can serve as a landmark to accurately locate the buccal branch of the facial nerve,thereby significantly reducing the risk of inadvertent injury to the buccal branch of the facial nerve and the parotid duct.
