Community-acquired pneumonia （CAP） refers to an infectious inflammation of the lung parenchyma （including the alveolar wall，that is，the broad pulmonary interstitium） acquired outside the hospital. Its common pathogens include streptococcus pneumoniae，respiratory viruses， mycoplasma pneumoniae， and so on. The related factors for the occurrence and development of CAP include patient characteristics （immune function，mucus production and clearance function，coagulation function，physical condition， and comorbidity） and pathogen characteristics （susceptibility，virulence，and antibiotic resistance）. The pathogenesis of CAP lies in immune deficiency，pathogen invasion，inflammatory response disorder，mucus production and clearance disorder， coagulation disorder， and so on. The pathogenesis of CAP in traditional Chinese medicine can be described as "vital Qi deficiency and toxic stasis". Vital Qi deficiency （lack of immunity） is the potential pathogenesis of the disease and easy to be invaded by external pathogens （respiratory pathogens）. Toxic stasis （inflammatory disorder，mucus production and clearance disorder，and coagulation dysfunction） is the key pathogenic factor. Vital Qi deficiency and toxic stasis are intermingled in a state of deficiency and excess，which suggests that the treatment of CAP lies in strengthening vital Qi and eliminating pathogenic factors. This involves strengthening vital Qi in the whole process to consolidate body resistance and nourish promordial Qi. It also involves clearing heat，eliminating phlegm，removing dampness，and dispelling stasis to dispel pathogenic toxins based on the syndrome differentiation. Its action mechanism is to regulate immune and inflammatory responses，resist pathogens，and improve mucus production and clearance， as well as coagulation disorders. Starting from the key pathogenesis of CAP，"vital Qi deficiency and toxic stasis"， this paper discussed the pathogenesis of CAP and summarized the action mechanism of vital Qi strengthening for detoxification in its treatment. It is intended to complement the theoretical system by identifying "vital Qi deficiency and toxic stasis" as the key pathogenesis underlying CAP and the scientific connotation of treating CAP with vital Qi strengthening for detoxification，thereby providing insights for its clinical application.

OBJECTIVE: To evaluate the effects of acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) on pain, anxiety, intrapartum blood loss, labor stage, and neonatal outcomes in primiparas. METHODS: One hundred primiparas were randomly divided into an acupuncture group (50 cases, 1 case was eliminated) and a control group (50 cases). The conventional obstetrical nursing was given in the control group. On the basis of the intervention in the control group, acupuncture was applied at bilateral Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) in the acupuncture group. The delivery mode and labor stage, the scores of visual analogue scale (VAS) for uterine contraction pain and Hamilton anxiety scale (HAMA) before and after acupuncture, the intrapartum/postpartum blood loss and massive hemorrhage, as well as the neonatal Apgar score after 1, 5, and 10 min of birth, were compared in the two groups. RESULTS: The cesarean section rate was 4.1% (2/49) in the acupuncture group, which was superior to 10.0% (5/50) in the control group (P<0.05). In the acupuncture group, the time of latent phase of 2-cm cervical dilation, active phase, first and second stages of labor, and total labor stage was shorter than that in the control group (P<0.001), the intrapartum blood loss and massive hemorrhage rate were lower than those in the control group (P<0.001, P<0.05). After acupuncture, the VAS and HAMA scores were decreased compared with those before acupuncture in the acupuncture group (P<0.001), the VAS and HAMA scores were increased compared with those before acupuncture in the control group (P<0.001). In the acupuncture group, the VAS and HAMA scores after acupuncture were lower than those in the control group (P<0.001), the changes of the VAS and HAMA scores before and after acupuncture were larger than those in the control group (P<0.001). There were no statistical differences in neonatal Apgar scores between the two groups (P>0.05). CONCLUSION Acupuncture at Hegu (LI4), Taichong (LR3) and Sanyinjiao (SP6) can effectively alleviate the pain and anxiety, shorten the labor stage, reduce the intrapartum blood loss and incidence rate of massive hemorrhage, and promote spontaneous delivery, thereby enhancing maternal comfort and safety in primiparas.

The p21-activated kinase 4 (PAK4), a key regulator of malignancy, is negatively correlated with immune infiltration and has become an emergent drug target of cancer therapy. Given the lack of high efficacy PAK4 inhibitors, we herein reported the identification of a novel inhibitor 13 bearing a tetrahydrobenzofuro[2,3-c]pyridine tricyclic core and possessing high potency against MIA PaCa-2 and Pan02 cell lines with IC₅₀ values of 0.38 and 0.50 μmol/L, respectively. This compound directly binds to PAK4 in a non-ATP competitive manner. In the mouse Pan02 model, compound 13 exhibited significant tumor growth inhibition at a dose of 100 mg/kg, accompanied by reduced levels of PAK4 and its phosphorylation together with immune infiltration in mice tumor tissue. Overall, compound 13 is a novel allosteric PAK4 inhibitor with a unique tricyclic structural feature and high potency both in vitro and in vivo, thus making it worthy of further exploration.

Objective:To explore the association between serum 25-hydroxyvitamin D[25(OH)D]and handgrip strength in middle-aged and elderly people in 5 cities of Western China.Methods:Based on the data of a cross-sectional survey conducted in the 5 cities of Western China from February to July 2023,the relevant demographic characteristics of people were collected by questionnaire,handgrip strength was collected by physical examination,and serum 25(OH)D was detected by HPLC-MS/MS.The association between the serum 25(OH)D and handgrip strength was analyzed using Logistic regres-sion and Chi-square test for between-group comparisons models.Results:The prevalence of 25(OH)D deficiency and insufficiency among the middle-aged and elderly people in the 5 cities of Western China was 52.9％and 34.5％,respectively.The people who were older,female,and sampled in winter had lower serum 25(OH)D levels(P＜0.05).The prevalence of loss of handgrip strength among the mid-dle-aged and elderly people was 25.3％.The prevalence of handgrip strength loss was higher in the aged 65-80 participants with 25(OH)D deficiency(45.0％)than in those with 25(OH)D insufficiency(32.6％)and 25(OH)D sufficiency(20.6％).The highest prevalence of loss of handgrip strength was found in the aged 75-80 participants with 25(OH)D deficiency(62.1％),followed by the 25(OH)D insufficient group(11.1％,P＜0.05).The study found that middle-aged and elderly people with 25(OH)D deficiency had a 1.4-fold increased risk of handgrip strength loss compared with those with 25(OH)D sufficiency(OR=2.403,95％CI:1.202-4.804,P=0.013).No significant association was found between 25(OH)D insufficiency and handgrip strength status in the middle-aged and elderly people.For every 5 μg/L increase in total serum 25(OH)D,the risk of handgrip strength loss reduced by 13.1％(OR=0.869,95％CI:0.768-0.982,P=0.025).For every 5 μg/L increase in serum 25(OH)D2,the risk of handgrip strength loss reduced by 24.1％(OR=0.759,95％CI:0.582-0.990,P=0.042).No significant association was found between serum 25(OH)D3 levels and the risk of hand-grip strength loss.The risk of handgrip strength loss in middle-aged and elderly people was reduced by 25.2％for each incremental increase in the total serum 25(OH)D levels(deficient,insufficient and suf-ficient)(OR=0.748,95％CI:0.598-0.936,P=0.011).The risk of handgrip loss was reduced by 40.0％for each incremental increase in serum 25(OH)D levels in the aged 65-80 and aged 65-69 participants,and by 80.0％for each incremental increase in 25(OH)D levels in the aged 75-80 parti-cipants.Conclusion:Serum total 25(OH)D and 25(OH)D2 levels are associated with handgrip strength status in middle-aged and elderly people in the 5 cities of Western China.

Objective To evaluates the impact of early application of neuromuscular electrical stimulation(NMES)on muscle strength,clinical outcomes,and long-term quality of life improvements in patients with severe acute pancreatitis(SAP)complicated with acute respiratory distress syndrome(ARDS).Methods A total of 75 patients diagnosed with SAP and ARDS admitted in Department of Critical Care Medicine of our hospital from September 2022 to August 2023 were recruited and then randomly divided into NMES group(n=37)and control group(n=38).After 16 patients were excluded,including 8 died during treatment,3 discharged and 5 received palliative care,there were finally 29 patients in the NMES group and 30 in the control group.Within 48 h after ICU admission,the NMES group received NMES 1 h per day,for 7 d in addition to standard rehabilitation intervention.While,the control group were given conventional interventions for rehabilitation.Assessments at baseline and post-treatment included the incidence of ICU-acquired weakness(ICU-AW),Medical Research Council(MRC)score,duration of mechanical ventilation,lengths of ICU and total hospital stays,and activity,thickness and thickening fraction of the diaphragm.Mortality rates and Barthel index(BI)for self-care ability in 1,3 and 6 months after discharge were recorded for follow-up assessments.Results The NMES group had significantly lower incidence of ICU-AW(P＜0.05),higher upper and lower limb MRC scores and overall MRC score at ICU discharge(P＜0.05),shorter durations of mechanical ventilation,ICU stay,and total hospital stay when compared with the control group(P＜0.05).There was no statistical difference in the BI at 1 month post-discharge between the 2 groups,but the indexes at 3 and 6 months were notably higher in the NMES group than the control group(P＜0.05).No obvious differences were observed between the 2 groups in terms of diaphragm activity,thickness,or thickening scores at enrollment,ICU discharge,or hospital discharge,nor in mortality rates at 1,3,and 6 months after discharge.Conclusion Combined NMES and early rehabilitation therapy can improve muscle strength and reduce length of hospital stay in SAP patients complicated with ARDS,and may enhance long-term quality of life.However,it does not significantly affect diaphragm function or mortality rates.

Objective:To investigate the safety and efficacy of the TRIANGLE operation after neoadjuvant chemotherapy in locally advanced pancreatic cancer(LAPC).Methods:This study is a retrospective case series analysis. Between January 2020 and December 2022, a total of 103 patients were diagnosed as LAPC who underwent neoadjuvant chemotherapy at the Pancreas Center, the First Affiliated Hospital of Nanjing Medical University. Among them, 26 patients (25.2%) underwent the TRIANGLE operation. There were 15 males and 11 females,with a age of (59±7) years (range: 49 to 74 years). The pre-treatment serum CA19-9( M(IQR)) was 248.8(391.6)U/ml (range: 0 to 1 428 U/ml),and the serum carcinoembryonic antigen was 4.1(3.8)μg/L(range: 1.4 to 13.4 μg/L). The neoadjuvant chemotherapy regimens included: mFOLFIRINOX regimen in 6 cases(23.1%), GnP regimen in 14 cases(53.8%), and mFOLFIRINOX+GnP regimen in 6 cases(23.1%). The follow-up duration extended until June 2023 or until the occurrence of the patient′s death or loss to follow-up. The Kaplan-Meier method was employed to estimate the 1-year and 3-year overall survival rates. Results:After neoadjuvant chemotherapy,CA19-9 levels decreased by 92.3(40.1)%(range:2.1% to 97.7%). Evaluation of the response to treatment revealed 13 cases(50.0%) of stable disease,11 cases(42.3%) of partial response,and 2 cases(7.7%) of complete response. The surgical operation consisted of 12 cases(46.2%) of pancreaticoduodenectomy,12 cases(46.2%) of distal pancreatectomy,and 2 cases(7.7%) of total pancreatectomy. Margin determination was based on the “standardised pathology protocol” and the “1 mm” principle. No R2 and R1(direct) resections were observed,while the R0 resection rate was 61.5%(16/26), and the R1(1 mm) resection rate was 38.5%(10/26).The R1(1 mm) resection rates for the anterior margin,posterior margin,transected margin,portal vein groove margin,and uncinate margin were 23.1%(6/26),19.2%(5/26),12.5%(3/24),2/14, and 1/12, respectively. The overall postoperative complication rate was 57.8%(15/26),with major complications including grade B/C pancreatic fistula 25.0%(6/24,excluding 2 cases of total pancreatectomy),delayed gastric emptying in 23.1%(6/26),wound complications 11.5%(3/26),postoperative hemorrhage 7.7%(2/26), chylous fistula 7.7%(2/26) and bile fistula 3.8%(1/26). No reoperation was performed during the perioperative period(<90 days). One patient died on the 32 nd day postoperatively due to a ruptured pseudoaneurysm. A total of 25 patients were followed up,with a follow-up time of 21(24)months(range: 8 to 42 months). During the follow-up period,8 cases(32.0%) died due to tumor recurrence and metastasis,while 17 patients(68.0%) remained alive,including 11 cases of disease-free survival,5 cases of distant metastasis,and 1 case of local recurrence. The overall survival rates at 1- and 3-year after the initiation of neoadjuvant chemotherapy were 95.8% and 58.9%, respectively. The overall survival rates at 1- and 3-year after surgery were 77.7% and 57.8%, respectively. Conclusion:Performing pancreatoduodenectomy according to the Heidelberg triangle protocol in LAPC patients after neoadjuvant chemotherapy might increase the R0 resection rate without increasing perioperative mortality or the incidence of major postoperative complications.

Objective:To investigate the prevalence of hyperuricemia (HUA) in Bozidun Kirghiz township of Xinjiang Aksu region, and to explore the risk factors for the occurrence of HUA in the local area.Methods:A cross-sectional survey study was conducted by randomly selecting 9 villages in Bozidun Kirgiz Township by the whole-group sampling method and questionnaire were distributed to the households. The questionnaire included: demographic information, history of past illness, personal history, and all subjects were measured for height, weight, blood pressure, abdominal circumference, etc. The diagnostic of HUA if the serum uric acid (SUA) level >420 μmol/L in men or >360 μmol/L in women. The incidences of HUA in different age, sex, food type and life style behavior were analyzed. T test, non-parametric test and Chi-square test were used to analyze the differences among the groups, and logistic regression was used to analyze the risk factors. Results:①A total of 2 138 subjects were surveyed, among which 68 patients were with HUA, the prevalence of HUA in Bozidun Kirghiz township, Aksu region in the general population was 3.18%(68/2 138); the prevalence rate in men was 4.60%(45/978), 45 patients were identified; and the prevalence rate in women was 1.98%(23/1 160), 23 patients were identified. The peak age of HUA in male and female patients was 51~60 years old. ②The prevalence of HUA was lower in those who consumed dairy products ( χ2=6.91, P=0.017), nuts ( χ2=8.43, P=0.038) and eggs ( χ2=7.38, P=0.023), and lower in those who consumed more. Different intake of cereals ( χ2=0.87, P=0.647), meat( χ2=0.82, P=0.662), vegetables and fruits( χ2=5.22, P=0.073) had no effect on the prevalence of HUA.③In terms of different life behaviors, the prevalence of HUA in men who had been smoking was higher than those who had never smoked (57.78%, 28.89%, 13.33%, χ2=8.16, P=0.017). In the relationship between drinking and HUA, the prevalence rates of male always drinking, ever drinking and never drinking were 80.00%, 11.11% and 3.89%, respectively, the difference was statistically significant ( χ2=6.67, P=0.038). ④Multi-factor logistic regression analysis showed that high BMI, old age, high TG, increased Cr and increased WBC were risk factors for the occurrence of HUA [ OR(95% CI)=1.13(1.04, 1.23), 1.03(1.00,1.05),1.39(1.00, 1.93), 1.03(1.02, 1.05), 1.27(1.07, 1.49), all P<0.05]. Conclusion:The prevalence of HUA in Bozidun Kirgiz township in Aksu prefecture of Xinjiang is lower than that in other areas with continental climate. High BMI, old age, high TG, increased Cr and increased WBC count are risk factors for the development of HUA .

Objective:To investigate the resuscitation effect of sodium bicarbonate Ringer's solution on traumatic hemorrhagic shock in patients.Methods:A randomized controlled trial was conducted on 70 patients with traumatic hemorrhagic shock who were admitted to Yiwu Central Hospital between February 2021 and February 2022. The patients were randomly assigned to a control group ( n = 35) and an observation group ( n = 35) using the random number table method. Both groups received routine treatment. The control group was given adequate resuscitation by intravenous injection of a compound sodium chloride injection, while the observation group received restricted resuscitation with sodium bicarbonate Ringer's solution. Related clinical indicators, coagulation function, lactate levels, hemorheological indicators, and incidence of complications were compared between the two groups. Results:The blood oxygen saturation, shock index, pulse pressure difference, and urine output in the observation group were (76.53 ± 2.56)%, (0.43 ± 0.07), (38.56 ± 6.52) mmHg (1 mmHg = 0.133 kPa), and (35.62 ± 4.21) mL/h, respectively. These values were all superior to those in the control group [(65.32 ± 3.21)%, (1.21 ± 0.13), (23.56 ± 4.23) mmHg, (23.65 ± 5.68) mL/h, t = 16.15, 31.25, 11.42, 10.06, all P < 0.001]. The prothrombin time, fibrinogen, activated partial thromboplastin time, and thrombin time in the observation group were (17.65 ± 0.83) seconds, (1.69 ± 0.89) g/L, (39.68 ± 0.52) seconds, and (17.86 ± 0.74) seconds, respectively. These values were significantly superior to those in the control group [(14.56 ± 0.86) seconds, (1.32 ± 0.23) g/L, (35.26 ± 0.16) seconds, and (16.02 ± 0.05) seconds, t = 15.30, 2.38, 48.06, 14.68, all P < 0.05]. The lactate level in the observation group was significantly lower than that in the control group [(2.24 ± 0.53) mmol/L vs. (2.94 ± 0.78) mmol/L, t = 4.39, P < 0.05]. The platelet cohesion, red blood cell deformability, and blood viscosity in each group were significantly reduced, and these indices in the observation group were superior to those in the control group ( t = 13.71, 5.64, 5.67, all P < 0.001). The incidence of complications in the observation group was significantly lower than that in the control group (8.6% (3/35) vs. 60.0% (21/35), χ2 = 10.08, P < 0.05). Conclusion:Restricted resuscitation with sodium bicarbonate Ringer's solution can improve clinical indicators, coagulation function, and lactate levels in patients with traumatic hemorrhagic shock. It can effectively improve hemodynamic indicators and reduce the incidence of complications. It is worthy of clinical promotion.

Objective To explore the clinical effects of hypoglycemic drugs on depression degree in patients with type 2 diabetes mellitus(T2DM).Methods A total of 160 newly diagnosed T2DM patients or T2DM patients who have not used hypoglycemic drugs in the past 3 months with mild to moderate depressive episodes and visited our outpatient department were enrolled in this study from January to December 2022.All the participants HbA1c were ranged from 7%to 9%.They were randomly divided into four groups:Metformin treatment group(Met,n=40),Met combined with sulfonylurea treatment group(Met+SUs,n=40),Met combined with DPP-4i treatment group(Met+DPP-4i,n=40),and Met combined with GLP-1 receptor agonist treatment group(Met+GLP-1RA,n=40).All the patients were scored with the Hamilton Depression Rating Scale(HAMD)and the Hamilton Anxiety Rating Scale(HAMA)in each group.Results The Met+DPP-4i and Met+GLP-1RA groups showed the most significant decrease in HAMD and HAMA scores after treatment(P<0.05),while the proportion of moderate depression and significant anxiety in HAMD decreased(P<0.05).Pearson correlation analysis showed that?HAMD,?HAMA were positively correlated with ?HbA1c in the Met+GLP-1RA group(P<0.05).Conclusion The combination of Met with DPP-4i and GLP-1RA has the most significant effect on improving the degree of depression in patients with T2DM and depression.
