Platycodonis Radix is the dry root of Platycodon grandiflorum of Campanulaceae, which has a variety of pharmacological effects and is a commonly used bulk Chinese medicine. In this study, the chloroplast genome sequences of six P. grandiflorum from different producing areas has been sequenced with Illumina HiSeq X Ten platform. The specific DNA barcodes were screened, and the germplasm resources and genetic diversity were analyzed according to the specific barcodes. The total length of the chloroplast genome of 6 P. grandiflorum samples was 172 260-172 275 bp, and all chloroplast genomes showed a typical circular tetrad structure and encoded 141 genes. The comparative genomics analysis and results of amplification efficiency demonstrated that trnG-UCC and ndhG_ndhF were the potential specific DNA barcodes for identification the germplasm resources of P. grandiflorum. A total of 305 P. grandiflorum samples were collected from 15 production areas in 9 provinces, for which the fragments of trnG-UCC and ndhG_ndhF were amplificated and the sequences were analyzed. The results showed that trnG-UCC and ndhG_ndhF have 5 and 11 mutation sites, respectively, and 5 and 7 haplotypes were identified, respectively. The combined analysis of the two sequences formed 13 haplotypes (named Hap1-Hap13), and Hap4 is the main genotype, followed by Hap1. The unique haplotypes possessed by the three producing areas can be used as DNA molecular tags in this area to distinguish from the germplasm resources of P. grandiflorum from other areas. The haplotype diversity, nucleotide diversity and genetic distance were 0.94, 4.79×10^-3 and 0.000 0-0.020 3, respectively, suggesting that the genetic diversity was abundant and intraspecific kinship was relatively close. This study laid a foundation for the identification of P. grandiflorum, the protection and utilization of germplasm resources, and molecular breeding.

Methods: This study established the MFSM method. To demonstrate its effectiveness, we applied this novel approach to analyze Danxi Granules (丹膝颗粒, DXG) and its constituent herbal materials. To begin with, the ultra-performance liquid chromatography (UPLC) was applied to obtain the chromatographic fingerprints of DXG and its constituent herbal materials. Next, the MFSM was leveraged to compress and integrate them into a new fingerprint with fewer analytical units. Then, we characterized the properties and variability of both the original and integrated fingerprints by calculating total quantum statistical moment (TQSM) parameters, information entropy and information amount, along with their relative standard deviation (RSD). Finally, we compared the TQSM parameters, information entropy and information amount, and their RSD between the traditional and novel fingerprints to validate the new analytical method. Results: The chromatographic peaks of DXG and its 12 raw herbal materials were divided and integrated into peak families by the MFSM method. Before integration, the ranges of the peak number, three TQSM parameters, information entropy and information amount for each peak or peak family of UPLC fingerprints of DXG and its 12 raw herbal materials were 95.07 − 209.73, 9390 − 183064 μv·s, 5.928 − 21.33 min, 22.62 − 106.69 min2, 4.230 − 6.539, and 50530 − 974186 μv·s, respectively. After integration, the ranges of these parameters were 10.00 − 88.00, 9390 − 183064 μv·s, 5.951 − 22.02 min, 22.27 − 104.73 min2, 2.223 − 5.277, and 38159 − 807200 μv·s, respectively. Correspondingly, the RSD of all the aforementioned parameters before integration were 2.12% − 9.15%, 6.04% − 49.78%, 1.15% − 23.10%, 3.97% − 25.79%, 1.49% − 19.86%, and 6.64% − 51.20%, respectively. However, after integration, they changed to 0.00%, 6.04% − 49.87%, 1.73% − 23.02%, 3.84% − 26.85%, 1.17% − 16.54%, and 6.40% − 48.59%, respectively. The results demonstrated that in the newly integrated fingerprint, the analytical units of constituent herbal materials, information entropy and information amount were significantly reduced (P < 0.05), while the TQSM parameters remained unchanged (P > 0.05). Additionally, the RSD of the TQSM parameters, information entropy, and information amount didn’t show significant difference before and after integration (P > 0.05), but the RSD of the number and area of the integrated analytical units significantly decreased (P < 0.05). Conclusion The MFSM method could reduce the analytical units of constituent herbal materials while maintain the properties and variability from their original fingerprint. Thus, it could serve as a feasible and reliable tool to reduce difficulties in analyzing multi-components within CMMs and facilitating the evaluation of their quality.

italic>Acanthopanax senticosus is one of the genuine regional herb in Northeast China. In this study, we identified the germplasm resources of commercial A. senticosus samples based on atpI and atpB_rbcL according to the previous chloroplast genome sequencing results, and determinated the content of syringin by HPLC to evaluated the quality of commercial samples. A total of 80 A. senticosus samples were collected from 47 cities in 24 provinces. DNA was extracted to amplify the products of atpI and atpB_rbcL by PCR. The results showed that 7 haplotypes (H2, H5, H8, H10, H12, H14, H23) were formed by the combined analysis of the two gene fragments. H2 from Yichun in Heilongjiang, Shangzhi in Harbin, Suihua in Heilongjiang, Fushun in Liaoning, Benxi in Liaoning, Changbai in Jilin and Jingyu in Jilin were the dominant genotype, representing 58.75% of the total samples. H14 and H23 were the unique haplotypes of the producing area. It is speculated that the commercial A. senticosus samples with haplotypes of H14 and H23 are from Raohe, Shuangyashan, Heilongjiang and Mingshui, Suihua, Heilongjiang, respectively. HPLC analysis indicated that the content of syringin in 73.96% of the samples met the Pharmacopoeia standards. There was a significant difference in the content of syringin among the samples, ranging from 0.003 7% to 0.524 5%, with a difference of 0.520 8%, indicating that the quality of the samples in the market of A. senticosus was uneven. However, there were no significant differences in the contents of syringin in the commercial A. senticosus among different haplotypes. The content of syringin in the haplotype H23 in the market sample is relatively high, so it may be a germplasm with better quality. This study researched the germplasm resources and medicinal materials quality of commercial A. senticosus samples and will help guide the commercial circulation, reasonable medication of A. senticosus, and the screening of excellent germplasm.

Objective To compare the clinical efficacies of video-assisted thoracoscopic segmentectomy versus lobectomy for early-stage non-small cell lung cancer.Methods The clinical data of 234 patients with stage ⅠA non-small cell lung cancer and undergoing different surgical methods under video-assisted thoracoscopy admitted to Chongqing Dianjiang General Hospital were retrospectively analyzed,and the patients were divided into the lung segment group and the lung lobe group according to their surgical methods.The clinical characteristics of the patients in the two groups were balanced by a 1-to-1 ratio matching through the propensity score matching method,and each group finally included 63 cases.The perioperative indicators containing operation time,intraoperative blood loss,postoperative thoracic drainage tube indwelling time,thoracic drainage volumes 24 hours and 48 hours after operation and postoperative hospital stay were compared of patients between the two groups.The incidence of postoperative complications such as air leakage>6 days,pulmonary infection,atelectasis,hemoptysis,and hoarseness in the two groups was collected.Results There was no significant difference in the operation time,intraoperative blood loss,thoracic drainage volumes 24 hours and 48 hours after operation,postoperative thoracic drainage tube indwelling time or incidence of postoperative complications of patients between the two groups(P>0.05).The postoperative hospital stay of patients in the lung segment group was shorter than that in the lung lobe group,with statistically significant difference(P=0.003).Conclusion For patients with stage ⅠA non-small cell lung cancer,video-assisted thoracoscopic segmentectomy has similar perioperative efficacy to lobectomy,while segmentectomy has a more significant advantage in shortening the hospital stay.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective To investigate the clinical efficacy and safety of Yiqi Huatan Tongluo Prescription(mainly composed of Fici Simplicissimae Radix,Notoginseng Radix et Rhizoma,Pinelliae Rhizoma Praeparatum,Poria,Nelumbinis Folium,and Glycyrrhizae Radix et Rhizoma,etc.)combined with drug-coated balloon(DCB)in the treatment of coronary heart disease(CHD)and to observe its effect on low-shear related serological indicators.Methods A total of 106 patients with CHD of qi deficiency and phlegm stasis obstructing collateral type who were scheduled to undergo percutaneous coronary intervention were randomly divided into a treatment group and a control group,with 53 cases in each group.The control group was treated with drug-eluting stent implantation,and the treatment group was treated with DCB.After the operation,the control group was given conventional antiplatelet aggregation drugs,and the treatment group was given oral administration of Yiqi Huatan Tongluo Prescription.The medication for the two groups lasted for 12 weeks.The changes in the serum levels of monocyte chemoattractant protein 1(MCP-1),interleukin 1 β(IL-1β)and vascular endothelial growth factor(VEGF)in the two groups were observed before and after treatment.Moreover,the traditional Chinese medicine(TCM)syndrome efficacy after treatment and the incidence of adverse events one year after operation were compared between the two groups.Results(1)After 12 weeks of treatment,the total effective rate for TCM syndrome efficacy of the treatment group was 88.68％(47/53),and that of the control group was 75.47％(40/53).The intergroup comparison(tested by chi-square test)showed that the TCM syndrome efficacy in the treatment group was significantly superior to that in the control group(P＜0.05).(2)The analysis of indicators related to endothelial dysfunction in the blood flow with low shear stress showed that after treatment,the levels of serum MCP-1,IL-1βand VEGF in the control group presented no obvious changes(P＞0.05),but the serum levels of MCP-1 and IL-1β in the treatment group were significantly lowered compared with those before treatment(P＜0.05).The intergroup comparison showed that the decrease of serum MCP-1,IL-1β and VEGF levels in the treatment group was significantly superior to that in the control group(P＜0.05).(3)The one-year follow-up after the operation showed that the total incidence of adverse events in the treatment group was 18.87％(10/53),and that in the control group was 20.75％(11/53).There was no significant difference between the two groups(P＞0.05).Conclusion Yiqi Huatan Tongluo Prescription combined with DCB has definite action on the targets related to endothelial dysfunction in coronary blood flow with low shear stress,which is conducive to reducing inflammatory response,improving the symptoms of angina pectoris and enhancing clinical efficacy.The incidence of adverse events did not increase one year after operation,indicating good safety and effectiveness.

Objective To elucidate the molecular genetic etiology of patients with disorders of sex development(DSD)using whole exome sequencing(WES),thereby enhancing our understanding of the underlying mechanisms of sexual development abnormalities.Methods Retrospective analysis was conducted on clinical data of 60 DSD patients diagnosed in the First People's Hospital of Yunnan Province between March 2008 and August 2021,with an additional family study for one proband.Genomic DNA was extracted from patients for WES analysis.Single nucleotide polymorphism(SNP)and insertions/deletion(InDel)tests were identified using SAMtools software in conjunction with established SNP and InDel databases.Copy number variations(CNVs)at the exon level were detected using ExomeDepth,while the potential pathogenicity of mutations was predicted with PolyPhen-2,Mutation taster and PyMol software,with Sanger sequencing employed for confirmation.Results The study included 22 patients with 46,XX DSD and 38 with 46,XY DSD.Among the 46,XX DSD patients,the SRY gene was detected in 14 patients.In the remaining 8 patients and a proband's families,single nucleotide site variations(SNVs)of NR5A1,PROKR2 and ANOS1 genes were identified in 2 patients,and CNVs in CYP21A2 gene were found in 4 patients.The pathogenicity of CYP21A2 EX1 Dup has been previously reported,while the remaining 3 CNVs were of uncertain significance,and no DSD-related mutations were detected in 2 patients.In the WES analysis of 46,XY DSD patients,10 pathogenic or likely pathogenic SNVs across 5 genes(SRY,AR,SRD5A2,CYP17A1,and NR5A1)were identified in 14 patients.Additionally,5 likely pathogenic CNVs involving the CYP21A2,AKR1C2,CBX2,and NR5A1 genes were detected in 5 patients,comprising 3 deletions and 2 duplications.Novel SNVs in NR5A1(c.722G>T,c.48C>G)and ANOS1 c.564A>T were identified,with no prior reports in relevant databases.The pathogenicity of CYP21A2 EX1 Dup is documented in related databases,while the remaining CNVs have not been previously reported.Conclusion The utilization of WES technology has enhanced the diagnostic potential for DSD,broadened the spectrum of known DSD-related gene mutations,and deepened our comprehension of DSD pathogenesis,offering valuable support for genetic counseling.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To observe the clinical efficacy of meridian massage in the treatment of cervical spondylotic radicu-lopathy.Methods Sixty-four patients with cervical radiculopathy treated from March 2020 to June 2023 were divided into the observation group and the treatment group,with 32 cases in each group.The observation group received conventional treat-ment,including 14 males and 18 females with an average age of(41.34±7.23)years old ranging from 32 to 55 years old;the disease duration ranged from 9 to 17 months with an average of(14.23±3.56)months;C5 and C6 nerve root compression oc-curred in 12 cases,C7 nerve root compression occurred in 17 cases,C8 nerve root compression occurred in 3 cases.The treat-ment group received massage therapy on the basis of conventional treatment,including 17 males and 15 females with an aver-age age of(40.86±6.97)years old ranging from 30 to 54 years old;the disease duration ranged from 8 to 18 months with an av-erage of(15.43±3.48)months;C5 and C6 nerve root compression occurred in 14 cases,C7 nerve root compression occurred in 16 cases,C8 nerve root compression occurred in 2 cases.The clinical efficacy was evaluated by visual analogue scale(VAS),neck disability index(NDI)and clinical assessment scale for cervical spondylosis(CASCS)before and after 2-week treatment,and the range of motion of cervical spine was compared before and after treatment.Results After 2-week treatment,the VAS and NDI scores of the treatment group and the observation group decreased,while the CASCS scores increased(P＜0.001).Af-ter 2-week treatment,the VAS and NDI scores were lower and the CASCS scores were higher in the treatment group than those of the observation group(P＜0.001).Comparing with those before treatment,the range of motion of flexion,extension,left flex-ion,right flexion,left rotation and right rotation after 2-week treatment increased in two groups(P＜0.05).Comparing with the observation group,the range of motion of flexion,extension,left flexion,right flexion,left rotation and right rotation increased more significantly in the treatment group(P＜0.05).Conclusion Meridian massage is effective in the treatment of cervical Spondylotic radiculopathy,which can effectively relieve neck pain,improve clinical symptoms and improve patient satisfaction.
