Objective To analyze the prescription patterns of Professor Huang Feng,a nationally renowned traditional Chinese medicine(TCM)practitioner,in treating osteomyelitis using data mining methods.Methods Prescription data from effective medical records of osteomyelitis treated by Professor Huang Feng between January 2018 and December 2022 were collected and screened.Microsoft Excel,SPSS Modeler 18.0,and SPSS Statistics 25 were used to analyze the frequency and the distribution of properties,flavors,and meridian tropism of prescribed medications,along with association rule analysis and cluster analysis of high-frequency drugs.Results A total of 137 prescriptions involving 86 Chinese medicinals were included.Eighteen high-frequency medicinals(frequency＞30 times)were identified,namely Glycyrrhizae Radix et Rhizoma,Astragali Radix,Coicis Semen,Angelicae Sinensis Radix,Smilacis Glabrae Rhizoma,Achyranthis Bidentatae Radix,Bletillae Rhizoma,Rehmanniae Radix,Paeoniae Radix Alba,Dendrobii Caulis,Polygalae Radix,Lablab Semen Album,Corydalis Rhizoma,Angelicae Dahuricae Radix,Drynariae Rhizoma,Sanguisorbae Radix,Poria,and Mume Fructus.Most of the prescribed medicinals were neutral in nature,sweet,bitter,and pungent in flavor,and had the meridian tropism of liver,spleen,and lung meridians.Association rule analysis yielded 67 drug association rules,and the high-support combinations were the drug combinations of Astragali Radix respectively with Coicis Semen,Angelicae Sinensis Radix,Smilacis Glabrae Rhizoma and Achyranthis Bidentatae Radix,reflecting the compatibility principles of supplementing and invigorating qi-blood,activating blood circulation to resolve stasis,and draining dampness to remove toxins.Cluster analysis revealed three core clusters:Cluster 1 consisted of Glycyrrhizae Radix et Rhizoma,Astragali Radix,Coicis Semen,Smilacis Glabrae Rhizoma,Angelicae Sinensis Radix,Bletillae Rhizoma,Paeoniae Radix Alba,Angelicae Dahuricae Radix,Mume Fructus,Polygalae Radix and Sanguisorbae Radix;Cluster 2 consisted of Rehmanniae Radix and Dendrobii Caulis;Cluster 3 consisted of Achyranthis Bidentatae Radix,Lablab Semen Album,Corydalis Rhizoma and Poria.Conclusion For the treatment of osteomyelitis,Professor Huang Feng follows the principle of combining supporting healthy qi with eliminating pathogens,focuses on clearing damp-heat and pathogenic toxins accompanied by activating blood circulation to resolve stasis,and lays stress on adaptation to local condition and activating spleen-stomach to reinforce vital qi.

Objective:To examine the funding landscape of the National Natural Science Foundation of China(NSFC)concerning research focused on the elderly as a specific demographic group.It seeks to analyze prevailing research hotspots and to offer insightful research ideas for scholars in this field.Methods:The study employed a retrospective research design.It involved retrieving data on approved projects related to the elderly from the NSFC's official database, covering the period from 2000 to 2020.The data set included variables such as funding year, project title, project category, supporting institution, and funding amount(application codes: H1901, H1902, H1903).Statistical analysis was conducted using Excel software, while visual analysis was performed using CiteSpace software.Results:Between 2000 and 2020, a total of 710 projects focused on geriatrics received funding, amounting to RMB 361, 032, 300, 000.This period exhibited a fluctuating upward trend in both the number of projects and the total funding amount.The primary funding categories were face-to-face projects and youth science fund projects, which together accounted for 44.4%(315/710), 34.4%(244/710)respectively.The distribution of project-relying units demonstrated significant regional imbalance, with Beijing, Zhejiang, Jiangsu, and Shanghai being the predominant areas.Notably, Nanjing Medical University, Peking University, and Shanghai Jiao Tong University ranked as the top three institutions, with funding percentages of 5.9%(42/710), 5.4%(38/710), and 4.5%(32/710), respectively.The research themes encompassed nucleoplasmic interactions, brain networks, and bioinformatics, among others.Conclusions:The NSFC has consistently provided funding for in-depth research in the critical field of geriatrics.The primary research directions focus on aspects such as the mechanisms of aging and the pathogenesis of neurological diseases associated with aging.With the application of innovative technologies and methodologies, significant breakthroughs and achievements are anticipated in geriatrics, contributing to the improvement of health outcomes and the enhancement of the quality of life for the elderly.

OBJECTIVE: To evaluate the clinical efficacy of ultrasound-guided needle knife release with different pathways for carpal tunnel syndrome (CTS). METHODS: Sixty CTS patients were randomly divided into a transverse group and a longitudinal group, with 30 patients in each group. The transverse group received the needle knife release under ultrasound above and below the median nerve along the short axis, while the longitudinal group received the needle knife release under ultrasound above the median nerve along the long axis. The patients' visual analogue scale (VAS) scores, Levine scores, and median nerve cross-section area (CSA) were assessed before treatment, on the 7th, 14th, and 30th days after treatment. The median nerve conduction indexes (motor conduction: latency [Lat], amplitude[Amp], motor conduction velocity [MCV]; sensory conduction: Lat, Amp, sensory conduction velocity [SCV]) were evaluated before treatment and on the 30th day after treatment. RESULTS: Compared before treatment, the VAS scores, Levine scores, and median nerve CSA were reduced in both groups on the 7th, 14th, and 30th days after treatment (P<0.05); the transverse group showed lower VAS and Levine scores and smaller CSA than those in the longitudinal group (P<0.05). On the 30th day after treatment, motor and sensory Lat was reduced (P<0.05), motor and sensory Amp was increased (P<0.05), and MCV and SCV were faster (P<0.05) in both groups. The transverse group had shorter Lat, higher Amp, and faster MCV and SCV than those in the longitudinal group (P<0.05). CONCLUSION The ultrasound-guided needle knife release with transverse and longitudinal pathways could both effectively alleviate pain and improve median nerve conduction in CTS patients, with the transverse pathway showing superior efficacy to longitudinal pathway.

Objective:To explore the antipyretic effect and partial mechanism of the pushing Tianheshui manipulation on lipopolysaccharide(LPS)-induced fever in young New Zealand rabbits. Methods:Thirty 50-day-old New Zealand rabbits were randomly assigned to five groups,including a normal group,a model group,a Tuina(Chinese therapeutic massage)group,a Tuina control group,and a drug group,with 6 rabbits in each group.All groups except for the normal group received LPS injections through the marginal ear vein to induce fever.One hour post-modeling,the Tuina and Tuina control groups received pushing Tianheshui manipulation and pushing manipulation on the medial middle of the hind limbs,respectively,administered every hour for a total of 3 interventions.The drug group was given acetaminophen oral liquid via gavage.Anal temperature was recorded every 30 min for 4.0 h to monitor temperature changes among groups.At 4.0 h post-modeling,hypothalamus samples from each group were analyzed using Western blotting(WB)and real-time quantitative polymerase chain reaction(RT-qPCR)to measure the relative expression levels of α-melanocyte-stimulating hormone(α-MSH),melanocortin 4 receptor(MC4R),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),nuclear factor-κB p65(NF-κB p65),and interleukin(IL)-1β proteins and their mRNAs. Results:Compared to the model group,the Tuina group showed a significant reduction in the anal temperature from 3.5 h to 4.0 h post-modeling(P<0.05).The Tuina control group did not show a significant temperature reduction from 0.5 h to 4.0 h post-modeling(P>0.05).The drug group exhibited a significant temperature reduction from 1.5 h to 4.0 h post-modeling(P<0.05).At 4.0 h post-modeling,compared to the model group,the Tuina group showed significantly increased relative expression of α-MSH and MC4R proteins and mRNAs(P<0.05)and significantly decreased relative expression of cAMP,PKA,NF-κB p65,and IL-1β proteins and mRNAs in the hypothalamus tissue(P<0.05).No significant differences were observed in these parameters in the Tuina control group compared to the model group(P>0.05). Conclusion:Pushing Tianheshui manipulation demonstrated a significant antipyretic effect,potentially linked to point specificity.Its mechanism may involve the α-MSH-mediated cAMP/PKA/NF-κB pathway.

Objective:This report presents the initial outcomes of endoscopic intermuscular dissection (EID), a novel technique introduced by our team for the diagnostic resection of early rectal cancer, focusing on the postoperative status of the vertical margins.Methods:On January 26, 2024, a patient with early rectal cancer (cT1-2N0M0) underwent Endoscopic Intermuscular Dissection. The EID procedure consists of six steps: (1) mucosal incision; (2) submucosal dissection; (3) superficial muscular layer incision; (4) intermuscular dissection; (5) complete tumor removal; (6) wound management.Results:The patient was a 70-year-old male with rectal cancer (cT1-2N0M0). The tumor was located on the left anterior wall of the rectum, approximately 9 cm from the anal margin, and measured 20mm in size. The dissection rate was 2.68 mm2/minute, and the total duration of the surgery was 109 minutes. The patient was successfully discharged on the fifth day after surgery. Pathological examination of the post-endoscopic surgery specimen revealed pT1b, with negative vertical margins. Follow-up after more than one month showed good recovery with no complications such as bleeding, perforation, infection, or stricture occurring. Colonoscopy indicated the presence of a granulation tissue suggestive of inflammation.Conclusion:Endoscopic Intermuscular Dissection for the diagnostic resection of early rectal cancer is potentially safe and may achieve negative vertical margins.

Purpose To evaluate the added value of time of flight(TOF)and point spread dispersion(PSF)reconstruction in mediastinal lymph node metastasis of lung cancer in 18F-FDG PET/CT imaging.Materials and Methods Sixty-eight lung cancer patients with mediastinal lymph node metastasis who underwent PET/CT examination in the First People's Hospital of Foshan from March 9,2020 to July 23,2021 were analyzed retrospectively.The different methods,including ordered subsets estimation maximization(OSEM),OSEM+TOF,OSEM+PSF,OSEM+TOF+PSF,were used to reconstruct the images.The resolution of different reconstruction algorithms for mediastinal lymph node metastasis of lung cancer,as well as the differences of signal-to-noise ratio(SNR)and standard uptake value(SUV)were compared,respectively.Results The highest values of SUVmean,SUVmax and SNR were obtained via OSEM+TOF+PSF method,which increased by 21.99%,22.86%and 60.14%,compared with conventional OSEM method(t=28.321,19.11,11.059,all P<0.01).The difference percentage in smaller lesions that diameter≤22 mm was significantly higher than that in larger lesions that diameter>22 mm(24.1%vs.21.1%,25.3%vs.19.3%,70.6%vs.63.3%;Z=-3.658,-4.313,-2.154,all P<0.05),and the difference percentage in low contrast lesions that SNR≤15.31 was significantly higher than that in high contrast lesions that SNR>15.31(23.6%vs.21.4%,25.3%vs.21.1%,85.7%vs.46.0%;Z=-3.519,-2.336,-5.106,all P<0.05).Among the evaluation results of lesion detectability of different reconstruction algorithms,OSEM+TOF+PSF image showed the mediastinal lymph node metastasis most clearly(87.4%of the lesions were clearly existing),which was significantly higher than that of OSEM image(73.1%of lesions were clearly existing)(χ2=11.704,P=0.001),however,the proportion of lesions clearly existing in OSEM+PSF image did not significantly increase compared with OSEM image(73.1%vs.75.8%;χ2=0.361,P=0.548).Conclusion The combination of TOF and PSF can significantly improve the detection ability,SNR and SUV of mediastinal lymph node metastasis of lung cancer,especially in small and low contrast lesions.

Objective:To investigate the effects of abdominal Tuina(Chinese therapeutic massage)on behavioral function,5-hydroxytryptamine 1A receptor(5-HT1AR),and synapsin-1(Syn1)in neonatal rats with hypoxic-ischemic brain injuries(HIBI). Methods:Forty healthy neonatal rats,born of 5 specific pathogen-free healthy pregnant rats,were randomly divided into a group for modeling(n=28)and a sham operation group(n=12)on the 7th day of birth.In the group for modeling,24 neonatal rats with HIBI successfully established by the Rice method were randomly divided into a model group(n=12)and an abdominal Tuina group(n=12).The abdominal Tuina group was given abdominal Tuina for 28 d from 24 h after modeling,and the other groups were put under the same conditions but without any treatments.Rats in each group were subjected to suspension tests on the 7th,14th,21st,and 28th days of intervention.After the intervention,the rat hippocampal tissue was collected and stained with hematoxylin-eosin to observe the pathological changes in the rat hippocampal CA1 region.The 5-HT1AR expression in rat hippocampal CA1 region was detected by immune-histochemistry.The Syn1 expression in rat hippocampus was measured by Western blotting method. Results:The cells were disordered,and edema and necrosis appeared in the hippocampal CA1 region of the model group.Cell arrangement was clear,and edema was improved obviously in the hippocampal CA1 region of the abdominal Tuina group.Compared with the sham operation group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression in the hippocampus decreased significantly in the model group after 21 d and 28 d of interventions(P<0.05).Compared with the model group,the suspension test scores,the number of 5-HT1AR positive cells,and Syn1 protein expression increased significantly in the abdominal Tuina group after 21 d and 28 d of interventions(P<0.05). Conclusion:Abdominal Tuina improves the behavioral function of upper limbs and up-regulates the expression levels of 5-HT1AR and Syn1 in the hippocampus of neonatal HIBI rats.

Objective:To investigate the feasibility of individualized primary clinical target volume (CTV) delineation in intensity-modulated radiotherapy for nasopharyngeal carcinoma (NPC).Methods:Clinical data of 87 consecutive patients newly diagnosed with lateralized NPC in Jiangsu Cancer Hospital between October 2016 and February 2018 were retrospectively analyzed. Lateralized NPC is defined as tumor invasion not exceeding the contralateral wall. According to the tumor spread, the primary CTV was optimized as follows: CTV2 only covered the medial part of the contralateral pterygopalatine fossa, whereas the contralateral foramen oval was not included; on the level of parapharyngeal space, the contralateral side of CTV only covered the posterior lateral lymph nodes, whereas the contralateral internal jugular vein was not regularly covered. Failure patterns and 5-year survival [local control rate (LCR), progression-free survival (PFS) and overall survival (OS)] were evaluated by Kaplan-Meier method. Paired t-test and rank-sum test were used to analyze the dose variation in the optimized region and adverse reactions. Results:The median follow-up time was 59.5 months. The 5-year LCR, PFS, and OS were 98.9%, 86.5% and 92.1%, respectively. There was no local recurrence in the optimized area of CTV. Dosimetric comparison results showed that the doses of parotid gland, temporal lobe, cochlea and middle ear on the contralateral side were reduced by 13.45%, 9.14%, 38.83%, and 29.36%, respectively. Four cases (4.6%) developed grade 3 hearing loss, all on the ipsilateral side. The optimized scheme significantly alleviated the hearing loss on the contralateral side compared to that on the ipsilateral side ( P<0.001). Other grade 3 late adverse reactions included cranial nerve injury, subcutaneous fibrosis in the neck and visual impairment, with 1 case each. Conclusion:Individualized primary CTV for lateralized NPC is feasible and safe, with obvious dosimetric advantages and reduced adverse reaction rate, which is worthy of clinical promotion.
