Objective To investigate the effect of angiotensinogen (AGT), angiotensin-converting enzyme (ACE) and AngII receptor (ATR) gene polymorphisms combined with climatic factors on the incidence of essential hypertension (EH) in Tibetan population in Gannan area. Methods A follow-up study was conducted to select 671 Tibetan people in Gannan area who were physically examined in April 2019 at the Health Management Center of the Second Hospital of Lanzhou University and agreed to be enrolled as a fixed cohort, and the blood pressure values of the enrolled subjects were measured after 3.5 years of follow-up, and a total of 501 cases were obtained. At the same time, the peripheral blood of all subjects was collected and the polymorphisms of AGT, ACE and ATR genes were detected by gene chip technology, and the possible interactions were analyzed by logistic regression model, fork generation method and multifactor-dimensionality reduction (MDR). Results Sunshine time was a protective factor for the incidence of hypertension in the Tibetan population of Gannan (OR=0.781), while relative humidity (OR=1.182), air pressure (OR=1.338) and temperature (OR=1.449) were the risk factors for the incidence of hypertension. According to the results of partial correlation analysis, temperature had no effect on the incidence of hypertension after controlling air pressure. There was an additive interaction between high air pressure and the polymorphisms of rs699 (OR=1.650, 95%CI: 1.293-2.399, P<0.001) and rs5049 (OR=1.711, 95%CI: 1.337-4.920, P<0.001) genes of AGT gene; there was a multiplicative interaction between relative humidity and rs699 (OR=0.472, 95%CI: 0.120-0.783, P<0.05);there was a multiplicative interactions between the altitude ≥ 3000m and rs699 (OR=1.503, 95%CI: 1.220-3.174, P<0.01), rs5049 (OR=1.673, 95%CI: 1.380-3.961, P<0.001) or rs2148582 (OR=0.519, 95%CI: 0.284-0.716, P<0.05).However, there was no interaction between climatic factors and ACE or ATR gene polymorphisms on the incidence of hypertension. Conclusion Climatic factors and altitude ≥3 000 m are closely related to the incidence of hypertension in the Tibetan population of Gannan area, and the interaction between AGT gene polymorphisms and climatic factors affects the incidence of hypertension in the population of this area.

OBJECTIVE To explore the characteristics and influential factors of pharmaceutical clinic service demands， providing evidence for optimizing pharmaceutical service models and facilitating pharmaceutical service models of pharmacist role transformation. METHODS A cross-sectional survey design was adopted， and 410 outpatient participants were selected from Fudan University Shanghai Cancer Center through convenience sampling for questionnaire administration from February to May 2025. Kano model was applied to analyze the demand attributes of 25 pharmaceutical services， while questionnaires were used to assess patients’ awareness and demand status. Subgroup analyses were conducted based on key demographic variables such as gender， age， educational attainment， and economic burdens， to SACA- systematically examine the differences in Kano attribute classification among patients in each subgroup. RESULTS The awareness rate of pharmaceutical outpatient services among patients was only 14.63%， yet those who were aware demonstrated a significantly higher demand rate for such services compared to those who were unaware （P＜0.001）. The demand for pharmaceutical clinic services exhibited a hierarchical characteristic： twelve items were identified as attractive attributes （e. g.， providing suggestions for more affordable treatment options， offering online consultation services， etc.）， five items as expected attributes （e.g.， having a good attitude and being able to patiently answer your questions， etc.）， three items as must-have attributes （e.g.， providing guidance on medication dosage and usage， providing guidance on medication precautions， etc.）， five items as indifferent attributes （e.g.， providing treatment plan recommendations based on the patient’s condition）. There were zero items classified as reverse attribute. Subgroup analysis revealed that female patients showed greater concern for “neat and clean attire of medical staff” than male patients （P＜0.001）； patients under 60 years of age demonstrated stronger demand for “providing treatment plan recommendations based on patients’ conditions” compared to patients aged 60 or above （P＝0.016）； those with below high school education placed greater emphasis on “providing guidance on medication precautions” compared to those with a high school education or above （P＝0.011）； patients with lower economic burdens exhibited stronger preferences for “neat and clean attire of medical staff ” （P＝0.002）. CONCLUSIONS The public awareness rate of pharmaceutical clinic services is considerably low； however， those who are aware of such services demonstrate significantly higher demand. The medication safety-related services and convenience-oriented demands should be prioritized in the development of pharmaceutical clinics. Moreover， the study also revealed that factors such as gender， age， educational level， and economic burdens exert significant influences on patients’ service demands.

BACKGROUND:Studies have shown that chronic apical periodontitis is one of the common inflammatory bone destruction diseases.Icariin can promote osteogenic differentiation,inhibit bone resorption,and may play a protective role in bone destruction caused by chronic apical periodontitis. OBJECTIVE:To investigate the effect of icariin on the proliferation and differentiation of MC3T3-E1 cells in the inflammatory environment stimulated by lipopolysaccharides. METHODS:Lipopolysaccharides were used to stimulate MC3T3-E1 cells to establish an inflammatory environment in vitro,and cell counting kit-8 was used to detect the best concentration and optimal action time of lipopolysaccharides.Cell counting kit-8 was used to detect the optimal concentration of icariin under the stimulation of lipopolysaccharides at a concentration of 1 μg/mL.Alkaline phosphatase detection,Real-time PCR and western blot assay were used to detect the effect of icariin on osteogenic differentiation of MC3T3-E1 cells in the inflammatory environment.Real-time PCR and western blot were used to detect the effects of icariin on the expression of interleukin-1β and interleukin-6 in MC3T3-E1 cells in the lipopolysaccharide-stimulated inflammatory environment. RESULTS AND CONCLUSION:Cell counting kit-8 results showed that the optimal concentration of icariin was 0.1 μg/mL.In the inflammatory environment,icariin enhanced the expression of alkaline phosphatase and promoted osteoblast differentiation.Compared with the lipopolysaccharide group,the expression of osteogenesis-related factors alkaline phosphatase and Runx2 was increased in the lipopolysaccharide+icariin group.Compared with the lipopolysaccharide group,the expression levels of inflammation-related factors interleukin-1β and interleukin-6 decreased in the lipopolysaccharide+icariin group.To conclude,lipopolysaccharides weaken the osteogenic ability of MC3T3-E1 cells and aggravate the inflammatory response,but icariin has a protective effect on them.

ObjectiveTo adapt the Stanford Expectations of Treatment Scale（SETS） into Chinese（C-SETS） and test the feasibility， validity and reliability of its application in patients with diarrhea-predominant irritable bowel syndrome（IBS-D） with liver-constraint and spleen-deficiency syndrome treated with traditional Chinese medicine（TCM）. MethodsWe obtained authorisation from the developer of the SETS， and followed the principle of "two-way translation" to translate the SETS by literal translation and back translation to form the C-SETS. Ninety-six IBS-D patients with liver-constraint and spleen-deficiency syndrome were enrolled as respondents and filled out C-SETS before receiving treatment； the feasibility was assessed by the recall rate， completion rate and the duration of filling out the scale； the reliability was assessed by Cronbach's α； the structural validity was assessed by exploratory and confirmatory factor analysis， and the content validity was assessed by correlation analysis. ResultsThe C-SETS consists of 10 items， with the 1st， 3rd， and 5th rating items constituting the Positive Expectations subscale， and the 2nd， 4th， and 6th rating items constituting the Negative Expectations subscale， each of which is rated on a 7-point Likert Scale. The recall of C-SETS was 100%（96/96）， the completion rate was 89.58%（86/96）； Cronbach's α for the Positive and Negative Treatment Expectations subscales were 0.845 and 0.854， respectively； exploratory factor analysis showed that the coefficient of commonality for all six entries was larger than 0.4， and that the six entries could be used by both factors to explain 77.092% of the total variance； validation factor analysis showed that the goodness-of-fit index， comparative fit index， root mean square of approximation error， canonical fit coefficient， and chi-square degrees of freedom ratio took the values of 0.943， 1.003， 0， 0.943， and 0.626， respectively； and the results of Spearman's analysis suggested that the C-SETS had good content validity. ConclusionThe C-SETS has well feasibility， reliability， and validity， which initially proves that it can be used as a tool to assess the treatment expectation of patients with IBS-D with liver-constraint and spleen-deficiency syndrome before receiving TCM treatment.

Objective:To explore the value of jellyfish sign, an abnormal ultrasonographic sign, in predicting adverse perinatal outcomes of women with complete placenta previa combined with placenta accreta spectrum disorders (PAS).Methods:This retrospective study analyzed the ultrasound images of 72 singleton gravidas, diagnosed with complete placenta previa combined with PAS, who underwent cesarean section at the First Affiliated Hospital of Nanjing Medical University between January 2020 and February 2023. Based on the presence and absence of the jellyfish sign in ultrasound images, these gravidas were divided into the jellyfish-sign group (15 cases, 20.8%) and the non-jellyfish-sign group (57 cases, 79.2%). The clinical data and perinatal outcomes of the two groups were analyzed. The adverse perinatal outcomes encompassed conditions such as abdominal aorta balloon block, uterine artery embolism, hysterectomy, postpartum hemorrhage, and neonatal intensive care unit (NICU) admission of their neonates. Statistical analysis was performed using two independent samples t-test, the Mann-Whitney U test and the Chi-square (or Fisher's exact) test. Results:(1) The jellyfish-sign group exhibited a higher parity [(1.6±0.7) times vs (1.2±0.6) times, t=2.01] and higher prenatal scores of placenta accreta [(12.3±1.5) scores vs (8.6±2.9) scores, t=6.59] than those in the non-jellyfish-sign group (both P<0.05). Among the 57 cases in the non-jellyfish-sign group, there were 14 cases of placenta creta (24.6%), 40 cases of placenta increta (70.2%), and three cases of placenta percreta (5.3%). Among the 15 cases in the jellyfish-sign group, nine cases were diagnosed with placenta increta, six with placenta percreta, and none with placenta creta. The difference in distribution between the two groups was statistically significant (Fisher's exact test, P<0.001). (2) Intraoperative blood loss [(for those who accepted abdominal aorta balloon block, 1 973±1 057) ml vs (1 211±576) ml, t=2.55], red blood cells transfused [4.0 U (2.0-23.0 U) vs 2.5 U (0.0-11.0 U), Z=－2.53], postoperative hospitalization time [(9.7±2.4) vs (7.5±2.2) d, t=3.36], the incidence of abdominal aorta balloon block [15/15 vs 38.6% (22/57), χ2=17.92], uterine artery embolism [for those who accepted abdominal aorta balloon block, 3/15 vs 1.8% (1/57), Fisher's exact test], and requiring blood transfusion [15/15 vs 63.2% (36/57), Fisher's exact test] were higher in the jellyfish-sign group than those in the non-jellyfish-sign group. However, the non-jellyfish-sign group had lower gestational age at delivery [(33.6±1.5) weeks vs (35.2±1.8) weeks, t=－3.24], and lower neonatal Apgar score at 1 min and 5 min [1 min: 8 scores (3-10 scores) vs 9 scores (4-10 scores), Z=－2.46; 5 min: 9 scores (7-10 scores) vs 10 scores (6-10 scores), Z=－2.02] (all P<0.05). There were no significant differences in emergency surgery rate, 24 h postoperative blood loss, neonatal birth weight, and proportion of NICU admission between the two groups. Additionally, no cases of hysterectomy or death were observed in the two groups. Conclusions:Ultrasound examination revealing jellyfish signs in patients with complete placenta previa and PAS is associated with an increased likelihood of adverse perinatal outcomes. Consequently, the management of these patients should be given greater attention.

Patients with hepatocellular carcinoma (HCC) and bone metastasis (BM) suffer from greatly reduced life quality and a dismal prognosis. However, BM in HCC has long been overlooked possibly due to its relatively low prevalence in previous decades. To date, no consensus or guidelines have been reached or formulated for the prevention and management of HCC BM. Our narrative review manifests the increasing incidence of HCC BM to sound the alarm for additional attention. The risk factors, diagnosis, prognosis, and therapeutic approaches of HCC BM are detailed to provide a panoramic view of this disease to clinicians and specialists. We further delineate an informative cancer bone metastatic cascade based on evidence from recent studies and point out the main factors responsible for the tumor-associated disruption of bone homeostasis and the formation of skeletal cancer lesions. We also present the advances in the pathological and molecular mechanisms of HCC BM to shed light on translational opportunities. Dilemmas and challenges in the treatment and investigation of HCC BM are outlined and discussed to encourage further endeavors in the exploration of underlying pathogenic and molecular mechanisms, as well as the development of novel effective therapies for HCC patients with BM.

Objective:To investigate the effect of three-dimensional printing technique assisted knee arthroplasty in the treatment of knee osteoarthritis with extraarticular deformities.Methods:Twelve patients with knee osteoarthritis and extraarticular deformities in the Sixth People's Hospital of Fuyang were selected as the study subjects from January 2016 to June 2018, and all patients were treated with total knee arthroplasty assisted by 3D printing.The operation time, intraoperative blood loss, preoperative simulated osteotomy value, intraoperative osteotomy value, postoperative drainage volume, joint activity score and Hospital for Special Surgery (HSS) score before treatment, 6 months after replacement and at the last follow-up were observed.Results:The intraoperative blood loss of patients was an average of (389.9±32.6)mL, and the drainage volume of patients was an average of (405.2±85.4)mL.There were no statistically significant difference between preoperative analogue value and intraoperative osteotomy value (all P>0.05). The HSS score ( P<0.001) and knee joint mobility ( P<0.001) were significantly higher at 6 months after operation and the last follow-up, and the mechanical axis deviation of lower limbs was significantly lower than that before operation ( P<0.001). Conclusion:Treatment of knee osteoarthritis with extra-articular deformity by using 3D printing assisted technique can restore the lower limbs and promote the recovery of knee joint function, which has satisfactory short-term effect and deserves further study and discussion.

Irreversible destruction of bronchi and alveoli can lead to multiple incurable lung diseases. Identifying lung stem/progenitor cells with regenerative capacity and utilizing them to reconstruct functional tissue is one of the biggest hopes to reverse the damage and cure such diseases. Here we showed that a rare population of SOX9 basal cells (BCs) located at airway epithelium rugae can regenerate adult human lung. Human SOX9 BCs can be readily isolated by bronchoscopic brushing and indefinitely expanded in feeder-free condition. Expanded human SOX9 BCs can give rise to alveolar and bronchiolar epithelium after being transplanted into injured mouse lung, with air-blood exchange system reconstructed and recipient's lung function improved. Manipulation of lung microenvironment with Pirfenidone to suppress TGF-β signaling could further boost the transplantation efficiency. Moreover, we conducted the first autologous SOX9 BCs transplantation clinical trial in two bronchiectasis patients. Lung tissue repair and pulmonary function enhancement was observed in patients 3-12 months after cell transplantation. Altogether our current work indicated that functional adult human lung structure can be reconstituted by orthotopic transplantation of tissue-specific stem/progenitor cells, which could be translated into a mature regenerative therapeutic strategy in near future.
