This article summarizes Professor SHAN Zhaowei's clinical experience in treating chronic atrophic gastritis based on the "three-unblocking method". It is believed that spleen and stomach qi deficiency， qi stagnation and blood stasis is the core pathogenesis of chronic atrophic gastritis， with the key lying in the dysfunction of spleen and stomach transportation and descending. Therefore， the "three-unblocking method" was proposed， namely promoting the flow of yang and and removing turbidity to restore spleen transportation， unblocking the bowels to resolve stagnation and benefit qi movement， unblocking the meridians to resolve stasis and eliminate masses. In clinic， it is often combined with microscopic syndrome differentiation via gastroscopy. For those with spleen deficiency and damp obstruction， or yang qi failing to transport， the treatment should unblock yang to transform turbidity； for those with food retention and bowel obstruction， or stagnant qi movement， the treatment should unblock bowels to resolve stagnation； for those with blood stasis and meridian obstruction， or internal masses retention， the treatment should unblock the collaterals and dissolve stasis. The prescription can choose self-formulated Ershen Sancao Decoction （二参三草汤） and combine modification， showing good clinical effectiveness.

Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2＜BMI≤23 kg/m2), a group B (23 kg/m2＜BMI≤29 kg/m2) and a group C (BMI＞29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

Objective To evaluate the association between paroxetine exposure and breast cancer risk by using a multi-omics approach and to elucidate the underlying molecular mechanisms. Methods A cross-sectional analysis was conducted using NHANES data from 2005 to 2016 to assess paroxetine exposure and breast cancer prevalence. Network pharmacology was employed to identify common targets and pathways, followed by Mendelian randomization analysis to validate causal relationships and molecular docking to further verify key interactions. Results Among 5520 participants, paroxetine users showed a 270% increased risk of breast cancer after multivariate adjustment (adjusted OR=3.70, 95%CI: 1.15-11.99, P=0.032). Network pharmacology identified 92 overlapping targets, with mTOR emerging as a central hub (IVW OR=1.09, 95%CI: 1.06-1.13, P=6.67×10⁻⁷). Molecular docking confirmed a high-affinity binding between paroxetine and mTOR (binding energy: −8.3 kcal/mol). Pathway enrichment analysis indicated that the PI3K-Akt signaling pathway, endocrine resistance, and chemical carcinogenesis were key mechanisms. Conclusion Paroxetine use may be linked to an increased risk of breast cancer, possibly mediated through the mTOR pathway.

Objective:To develop and validate the Pain nursing Competency Evaluation Questionnaire for Nursing Students to provide an effective tool for measuring the pain management competency of nursing students in China.Methods:The questionnaire was constructed through literature review, semi-structured interviews, focus group discussions, Delphi expert consultation, and a pre-survey.

It can be used as a tool to assess nursing students′ competency in pain care and provides a reference for the design and optimization of pain care courses and clinical practice programs for nursing students in undergraduate institutions.

Objective To investigate the influence of body mass index(BMI)on individualized analgesic effect,inflammatory factors and safety of sufentanil in elderly patients after proximal femoral nail anti-rotation(PFNA)surgery.Methods A total of 161 elderly patients who received PFNA surgery in Nanjing Drum Tower Hospital Group Suqian Hospital from January 2022 to December 2023 were selected as study subjects.Patients with BMI<18.5 kg/m2 were set as Group A,patients with BMI ranging from 18.5 kg/m2 to 23.9 kg/m2 were set as Group B,patients with BMI ranging from 24.0 kg/m2 to 35.0 kg/m2 were set as Group C.After operation,individualized analgesia was performed with an intravenous patient-controlled analgesia pump of 2 μg/kg sufentanil based on body weight,and the postoperative pain degree,inflammatory factors,analgesia condition and adverse reactions of patients in the three groups were compared.Results At 8 hours,12 hours,24 hours and 48 hours after surgery,the pain visual analogue scale(VAS)scores of patietns in group B and group C were significantly lower than those in group A(P<0.05).At 12 hours,24 hours and 48 hours after surgery,the pain VAS scores of patients in group C were significantly lower than those in group B(P<0.05).The levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),and interleukin-6(IL-6)1 day after surgery of patients in group B and group C were significantly lower than those in group A(P<0.05).The pressing times of analgesia pump and the duration of obvious pain within 48 hours after surgery of patients in group A were significantly more/longer than those in group B and group C(P<0.05),and the analgesic satisfaction score was significantly lower than those in group B and group C(P<0.05).The total incidence of analgesic adverse reactions in group C was significantly higher than those in group A and group B(P<0.05).Conclusion BMI may affect the individualized analgesic effect,inflammatory factors and safety of sufentanil in elderly patients undergoing PFNA surgery.Underweight patients may have insufficient analgesia,while overweight or obese patients may have excessive analgesia,which may affect the analgesic safety.

Objective To explore the correlation between the expression level of serum fibrinogen-like protein 1(FGL1)and the indexes of metabolism and renal function in patients with diabetic nephropathy(DN)and diabetes mellitus(DM),and provide reference for clinical diagnosis and treatment.Methods From January 2017 to April 2023,30 patients with DM and treated in Jiangsu Province Hospital of Chinese Medicine were selected as the DM group,68 patients with DN were selected as the DN group,and 36 healthy subjects were selected as the control group.The DN group was further divided into the early DN(DN-E)group(n=38)and the late DN(DN-A)group(n=30)according to whether there was a large amount of proteinuria and the severity.Clinical data such as serum albumin(ALB),estimated glomerular filtration rate(eGFR)and albumin-to-creatinine ratio(ACR)were collected.Serum FGL1 level was detected by enzyme-linked immunosorbent assay(ELISA).Pearson linear correlation was used for correlation,the diagnostic value was analyzed by ROC curve.Results Compared with the control group,the levels of ACR,FGL1 in patients with DM group increased,the levels of eGFR decreased,and the differences were statistically significant(t=5.686,4.336,-4.683,all P<0.05).Compated with the DM group,the levels of ACR,FGL1 in patients with DN-E group was increased,and the level of eGFR was decreased,and the differences were statistically significant(t=5.275,3.454,-4.969,all P<0.05).Compared with the DN-E group,the levels of ACR,FGL1 in the DN-A group were increased,the levels of eGFR were decreased,and the differences were statistically significant(t=7.881,7.051,-5.596,all P<0.05).Serum FGL1 level was negatively correlated with ALB and eGFR(r=-0.638,-0.547,all P<0.05),and positively correlated with ACR(r=0.691,P<0.05).The AUC(95%CI),specificity and sensitivity of serum FGL1 level in the diagnosis of DN were 0.947(0.908～0.987),100%and 82.4%,respectively.Conclusion The level of serum FGL1 in DN and DM patients is high,and the level of serum FGL1 is closely related to the common metabolic indexes such as ALB,eGFR and ACR in the diagnosis of DN,which may have certain clinical diagnostic value.

Objective To explore the effects of different CO2 pneumoperitoneum pressures during surgery on overweight or obese patients with laparoscopic panhysterectomy in Trendelenburg position.Methods A total of 88 overweight or obese patients who underwent laparoscopic panhysterectomy were selected and randomly divided into the low-pressure group and the high-pressure group according to random number table method,with 44 patients in each group.All patients used CO2 as the pneumoperitoneum medium during surgery,with 10 mmHg of CO2 pneumoperitoneum pressure in the low-pressure group and 15 mmHg of CO2 pneumoperitoneum pressure in the high-pressure group.The operation-related indexes,respiratory indicators,nasopharyngeal temperature and adverse reactions of patients were compared between the two groups.Results There was no significant difference in the surgical time,blood loss,intraoperative infusion volume,incidence of organ injury,and laparotomy rate between the two groups(P>0.05).The recovery time of anesthesia of patients in the low-pressure group was shorter than that in the high-pressure group(P<0.05).At 30 minutes after the establishment of pneumoperitoneum,the peak airway pressure(Ppeak)and plateau pressure(Pplat)of patients in the high-pressure group were significantly higher than those in the low-pressure group(P<0.05),while the dynamic lung compliance(Cdyn)of patients in the high-pressure group was significantly lower than that in the low-pressure group(P<0.05).At 60 minutes after the establishment of pneumoperitoneum and the end of pneumoperitoneum,the nasopharyngeal temperature of patients in the high-pressure group were significantly lower than those in the low-pressure group(P<0.05).The incidences of intraoperative hypothermia and shivering in the high-pressure group were significantly higher than those in the low-pressure group(P<0.05).Conclusion Compared with 15 mmHg of CO2 pneumoperitoneum pressure,10 mmHg of CO2 pneumoperitoneum pressure on overweight or obese patients with laparoscopic panhysterectomy in Trendelenburg position does not increase surgical difficulty,and the patients has lower airway pressure,better lung compliance,fewer adverse reactions,and faster recovery,which can also avoid intraoperative hypothermia.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Cervical cancer is a common gynecological malignancy, and radiotherapy plays a crucial role in its treatment. However, conventional radiotherapy for cervical cancer often leads to bone marrow damage, considerably affecting patients’ quality of life and treatment outcomes. In recent years, the application of intensity-modulated radiotherapy (IMRT) and magnetic resonance imaging (MRI) technologies has provided novel solutions to this issue. IMRT optimizes dose distribution, minimizing radiation exposure to surrounding normal bone marrow tissues and thus considerably reducing damage. MRI allows for accurate tumor localization and monitoring, including organs at risk, such as the bone marrow, and providing precise guidance for radiotherapy. This article analyzes the feasibility and potential benefits of MRI-guided pelvic IMRT for bone marrow protection in cervical cancer, aiming to offer a basis for precise and effective bone marrow protection strategies in cervical cancer radiotherapy.
