Objective To explore the symptom prevalence in the patients with pulmonary nodules in Lingnan area and to investigate the influencing factors,thus to provide data support for the construction of differentiation and treatment system of symptoms-syndrome elements-syndromes-constitutions for patients with pulmonary nodules,and to promote the establishment of secondary prevention system of lung cancer with the in-depth participation of traditional Chinese medicine(TCM).Methods A cross-sectional study was adopted to investigate patients with pulmonary nodules who admitted in the First Affiliated Hospital of Guangzhou University of Chinese Medicine from August 2023 to January 2024.Data collection covered the basic information,clinical characteristics and symptoms of the patients.Likert four-level scale was used for the grading of the severity of the symptoms,multivariate linear regression was adopted to construct three regression models,and then the factors influencing the severity of symptoms of patients with pulmonary nodules were explored.Results(1)A total of 274 patients were enrolled in the analysis,including 160 females and 114 males,with a mean age of(54.44±12.00)years old and the symptom scores averaging(3.97±3.80)point.The included patients with pulmonary nodules were characterized by females outnumbering males,a higher proportion of middle-aged and elderly people,multiple pulmonary nodules being more common.(2)The analysis of the symptoms of the 274 patients showed that symptoms with an incidence over 30%were fatigue(116 cases,42.34%),cough(105 cases,38.32%),expectoration of white sputum(89 cases,32.48%),and irritability and distress(87 cases,31.75%).(3)Multivariate linear regression analysis after variable adjustment suggested that the overall symptomatic severity in the male was milder than that in the female[β=-1.67,95%CI(-2.67,-0.68),P<0.001],and symptom score was positively correlated with age[β=0.07,95%CI(0.03,0.10),P<0.001],history of exposure to secondhand smoke[β=1.27,95%CI(0.26,2.27),P=0.015],history of exposure to other hazardous substances[β=1.96,95%CI(0.39,3.53),P=0.015],and history of allergy[β=2.38,95%CI(1.22,3.54),P<0.001]significantly.Conclusion The overall symptoms of patients with pulmonary nodules in Lingnan area are mild,and the high prevalence of symptoms are fatigue,cough,expectoration of white sputum,and irritability and distress.The symptom severity is correlated with gender,age,history of exposure to secondhand smoke,history of exposure to other hazardous substances,and history of allergy.

This article summarizes Professor Li Ziyong's clinical experience with the round-sharp needle.As one of the core needle types in the Huang Di Nei Jing(The Yellow Emperor's Inner Classic)nine-needle system,the round-sharp needle has long been marginalized in clinical practice due to historical discontinuities in its transmission and insufficient research on its morphological characteristics,resulting in its unique therapeutic value remaining largely unrecognized.Through nearly three decades of clinical practice,Professor Li innovatively proposed the acupuncture concept of"unblocking passages and guarding the pivotal mechanism",guided by the Yellow Emperor's Inner Classic principle that"ordinary practitioners focus on the joints,while superior practitioners focus on the pivotal mechanisms".Under this theoretical framework,he has extensively applied the round-sharp needle in clinical settings.With its unique design combining rounded and sharp features,the round-sharp needle demonstrates remarkable clinical efficacy by intervening at the fascial layer and releasing local fascial adhesions.It exhibits rapid onset and stable therapeutic outcomes.This article systematically reviews Professor Li's understanding of the round-sharp needle,its key operational techniques,and clinical case studies,aiming to establish a replicable paradigm for its modern application and promote the clinical translation of classical acupuncture theory.

The view of"inferior practitioner guarding the gate while the superior practitioner keeping the trigger"during the clinical practive was recorded in in Huang Di Nei Jing(Huangdi's Cannon of Medicine).This paper probes into the diagnosis and treatment of bi-syndrome from the perspecitve of"guarding the gate"and"keeping the trigger".It is proposed that the lesion of five body constituents(i.e.,skin,vessel,muscle,tendon,and bone)constitutes the injured"gate"of bi-syndrome,and the disharmony of qi and blood constitutes the"trigger"of the onset of bi-syndrome.The location of lesions will be found through examining the gate,and the state of qi and blood will be confirmed after checking the trigger.For the treatment of bi-syndrome,"guarding the gate"is to enable the normality of five body constituents,and"keeping the trigger"is to maintain the abundance and harmony movement of qi and blood,which cover the consideration of focal lesions and the regulation of holistic qi and blood."Guarding the gate"is as important as"keeping the trigger",and the two are interrelated.Only by carefully examining the gate of the lesions and strictly checking the trigger of qi-blood movement,it is possible to identify the deficiency of healthy qi and the excess of the pathogens,the nature of the pathogens and the severity of illness of bi-syndrome,and then the corresponding therapeutic methods can be performed to achieve the efficacy.The view of"guarding the gate"and"keeping the trigger"expands the clinical approach to the diagnosis and treatment of bi-syndrome.

Objective:To investigate the application value of digital X-ray radiotherapy and single photon emission computed tomography(SPECT)radionuclide bone imaging in the diagnosis of intertrochanteric fracture of femur.Methods:A total of 70 patients who were diagnosed as intertrochanteric fracture of femur in Shijiazhuang People's hospital from January 2017 to December 2020 were selected,and they were divided into study group and control group according to random number method,with 35 cases in each group.Digital X-ray radiography combined with SPECT radionuclide bone imaging was used in the study group,and digital X-ray radiography was used in the control group.And then,the accuracy of the diagnostic results between the two groups were compared.Results:The radiographic examination indicated that 31 cases(88.6%)of 35 cases in the study group were confirmed,and 24 cases(68.6%)of 35 cases in the control group were confirmed.The diagnostic accuracy rate of the study group was significantly higher than that of the control group,and the difference was statistically significant(x2=4.158,P<0.05).The preoperative imaging diagnosis indicated that diagnosed number of fracture blocks in the study group was(3.57±0.50),which was significantly higher than that(2.67±0.40)in the control group,and the difference of that between two groups was statistically significant(t=8.315,P<0.05).In the actual intraoperative examining for bone continuity,5 cases were continuity and 30 cases were non-continuity.In the bone stability,13 cases were stability and 22 cases were non-stability.The study group was closer to intraoperative bone continuity and bone stability,and the differences of them between two groups were statistically significant(x2=12.857,4.644,P<0.05),respectively.Conclusion:The combination of digital X-ray radiography and SPECT radionuclide bone imaging has higher diagnostic value for intertrochanteric fracture of femur,which can provide important reference for clinical diagnosis.

【Objective】 To explore the effectiveness and safety of polyglycolic acid (PGA) and hydroxypropyl methylcellulose (HPMC) composite materials in distal pancreatectomy postoperative suturing. 【Methods】 We selected 36 healthy adult beagles and divided them randomly into observation group and control group, with 18 distal pancreatectomy surgeries in each group. The observation group used PGA+HPMC composite materials for incision reinforcement while the control group used NEOVEIL for incision reinforcement. 3 days before surgery, 3 days after surgery, and before dissection, blood routine tests were performed on each group of experimental dogs. Observation periods of 2-week, 4-week and 8-week were set, and six animals at each observation point were evaluated for histological examination of heart, liver, spleen, lung, and kidney tissues, hard tissue slice pathological diagnosis, and safety evaluation. 【Results】 There was no significant difference between the observation group and the control group in the preoperative blood routine test. Repeated measures ANOVA results showed differences in the mean values of white blood cell count (WBC) ( F=14.875, P=0.001), mean corpuscular hemoglobin concentration (MCHC) (F=5.049,P=0.009), neutrophil percentage (Neu%) (F=4.794, P=0.011), red blood cell count (RBC) (F=6.591, P=0.002), hemoglobin (HGB) (F=8.154, P=0.001), hematocrit (HCT) (F=5.281, P=0.007), platelet count (PLT) (F=6.560, P=0.014), red blood cell distribution width coefficient of variation (RDW-CV) (F=33.950, P=0.039), or lymphocyte percentage (Lym%) (F=3.299, P=0.043) at different time points. However, the observation group and the control group did not differ, and the interaction between time and group had no significant effect on the above indicators, suggesting that both groups of dogs had inflammatory response or surgical stress. For the 8-week postoperative hard tissue pathological section score, there was no significant difference between the observation group and the control group in the inflammation and necrosis related score, fibrosis, repair or other related scores and total score (P>0.05). In the dissection at 8 weeks after surgery, no obvious damage to the heart, liver, spleen, lung, kidney, or other organs was found in both groups, nor was there any residual suture material, pancreatic fistula, or pancreatitis, indicating that the suture materials in both groups had been completely absorbed and metabolized, and the incision healed well without causing adverse effects on the visceral organs. 【Conclusion】 PGA and HPMC are effective and safe postoperative suture materials, with good biodegradability, biocompatibility, suture strength, and wound healing quality. They can be comparable to traditional absorbable reinforcement materials in distal pancreatectomy postoperative suturing, thus providing scientific basis for their clinical application.

Inducing durable and effective immunity against severe acute respiratory syndrome Coronavirus 2 (SARS-CoV-2) via vaccination is essential to combat the current pandemic of coronavirus disease 2019 (COVID-19). It has been noticed that the strength of anti-COVID-19 vaccination-induced immunity fades over time, which calls for an additional vaccination regime, as known as booster immunization, to restore immunity among previously vaccinated populations. Here we report a pilot open-label trial of a third dose of BBIBP-CorV, an inactivated SARS-CoV-2 vaccine (Vero cell), on 136 participants aged between 18 to 63 years. Safety and immunogenicity in terms of neutralizing antibody titers and cytokine/chemokine responses were analyzed as the main endpoint until day 28. While systemic reactogenicity was either absent or mild, SARS-CoV-2-specific neutralizing antibody titers rapidly arose in all participants within 4 weeks, surpassing the peak antibody titers elicited by the initial two-dose immunization regime. Broad increases of cellular immunity-associated cytokines and chemokines were also detected in the majority of participants after the third vaccination. Furthermore, in an exploratory study, a newly developed recombinant protein vaccine, NVSI-06-08 (CHO Cells), was found to be safe and even more effective than BBIBP-CorV in eliciting humoral immune responses in BBIBP-CorV-primed individuals. Together, these results indicate that a third immunization schedule with either homologous or heterologous vaccine showed favorable safety profiles and restored potent SARS-CoV-2-specific immunity, providing support for further trials of booster vaccination in larger populations.

The morbidity and mortality of lung cancer were the highest in malignant tumors. In recent years, with the update of clinical assistant examination technology and the popularization of physical examination, especially the development of CT examination, more and more lung cancer in early stage are found in the form of pulmonary nodules. Surgery treatment should be considering as the first choice for early lung cancer. At present, various 3D technologies have been widely used in the field of medicine, leading the thoracic surgery to the direction of minimal invasion and precision. This review focuses on the current application of 3D technology in the perioperative period of early lung cancer.

Objective:To explore the effects of Carolina care model in standardized training of nurses.Methods:Convenience sampling was used to select 35 nurses who entered the Department of Cardiology for standardized training (referred to as training nurses) from October 2018 to March 2019 in a Class Ⅲ Grade A hospital in Changchun as control group, and 37 nurses who entered the Department of Cardiology from May to October 2019 were selected as observation group. Control group carried out routine training, and observation group implemented a training plan based on the Carolina care model. Training effects were evaluated with the Nursing Caring Characters Assessment Tool, Clinical Communication Competence Scale and Patient Satisfaction Questionnaire.Results:After training, the scores of all dimensions of the Nursing Caring Characters Assessment Tool of nurses in observation group were higher than those in control group with statistically significant differences ( P<0.05) . After training, the scores of all dimensions of the Clinical Communication Competence Scale of nurses in observation group were higher than those in control group, and the differences were statistically significant ( P<0.05) . In observation group, patients' satisfaction with training nurses was higher than that in control group with a statistically significant difference ( P<0.05) . Conclusions:The application of Carolina care model in standardized training of nurses can not only improve nurses' humanistic care and communication competence, but also improve patient satisfaction.

Objective: To evaluate the clinical efficacy of percutaneous tibial nerve electrical stimulation in the treatment of chronic pelvic pain syndrome. Methods: The clinical data of 28 patients with chronic pelvic pain syndrome from January to November 2018 in Dalian Third People′s Hospital were retrospectively analyzed. The patients were treated with percutaneous tibial nerve stimulation. The number of urination in 24 h, number of nocturnal urination, urine volume per urination, quality of life (QOL) score and digital pain intensity score before treatment and after treatment were compared; the patients were followed up for 3 months, and the recurrence and adverse reaction were observed. Results: Compared with those before treatment, the number of urination in 24 h and number of nocturnal urination after treatment were significantly lower: (11.6 ± 6.4) times vs. (20.6 ± 7.8) times and (2.5 ± 1.2) times vs. (5.2 ± 2.6) times, and the urine volume per urination increased significantly: (181.2 ± 65.6) ml vs. (125.4 ± 58.2) ml, the QOL score and digital pain intensity score decreased significantly: (2.6 ± 1.4) scores vs. (5.1 ± 0.8) scores and (2.9 ± 1.3) scores vs. (6.9 ± 1.4) scores, and there were statistical differences (P<0.05). During the follow-up period, none of the patients had recurrent symptoms and obvious adverse reaction. Conclusions Percutaneous tibial nerve stimulation is an effective way to treat chronic pelvic pain syndrome.
