ObjectiveTo investigate the general situation， dietary factors， and clinical features of patients with recurrent primary common bile duct stones， and to provide a basis for effective prevention of stone recurrence. MethodsA retrospective analysis was performed for 23 730 patients who underwent cholecystectomy due to cholelithiasis in Department of Hepatobiliary， Pancreatic and Spleen Surgery， Inner Mongolia People’s Hospital， from January 2013 to December 2023， and according to the presence or absence of recurrence of primary common bile duct stones after surgery， 334 patients were divided into recurrence group. The recurrence group was further analyzed based on sex in terms of recurrence rate， recurrence cycle， recurrence age， recurrence type， and general， disease， imaging， and dietary factors. The independent-samples t test was used for comparison of continuous data between two groups， the chi-square test was used for comparison of categorical data between two groups. ResultsThere were 334 cases of recurrence of primary bile duct stones after cholecystectomy， with a recurrence rate of 1.41%， and the highest frequency of recurrence cycle was observed in 10 years after surgery， with a significant difference in recurrence cycle between the male and female patients （t=5.238， P<0.001）. There was a significant difference in the recurrence rate of stones after surgery between the patients with simple gallstones and those with gallbladder and common bile duct stones at initial diagnosis （1.23% vs 2.76%， χ²=42.104， P<0.001）. The patients with recurrence aged >60 years accounted for the highest proportion in the whole population and in both male and female populations， and 92% were Han residents； 10% of the patients with recurrence had a family history of gallstones， and as for comorbidities， the patients with hypertension accounted for the highest proportion. Among the patients with recurrence， the patients with smoking or drinking accounted for 76.7% and 10.3%， respectively. As for body weight， 63.8% of the patients with recurrence had a normal body mass index （BMI）， and 23.2% of the patients were overweight； compared with body weight at the time of the first gallbladder surgery， a reduction in body weight was observed in 60.1% of the patients with recurrence， while an increase in body weight was observed in 22.9% of the patients with recurrence. There were significant differences between the male and female patients with recurrence in age composition， ethnicity， the type of place of residence， comorbidities， smoking， drinking， BMI， and the change in body weight （all P<0.001）. As for the type of stone recurrence， the ratio of multiple stones， solitary stones， and muddy stones was 74∶15∶11， and the stone size of <1 cm， 1-2 cm， and >2 cm accounted for about 40.5%， 48.8%， and 10.6%， respectively. As for the surgical procedure， the patients undergoing laparotomy accounted for 66.1%， and those undergoing laparoscopy accounted for 33.9%. The patients with various types of dyslipidemia accounted for a percentage of<30%. There were significant differences between the male and female patients with recurrence in the type of stones at initial onset， the type and size of stones， and surgical procedure （all P<0.001）. Imaging data showed that 4 patients had an abnormal structure of the bile duct， manifesting as long and curve cystic ducts， and 73.1% of the patients had common bile duct dilatation after surgery. The follow-up of dietary factors showed irregular diets in 55.8% of the patients with recurrence. As for the dietary structure， meat and staple food accounted for 43.8% and 37.8%， respectively， which showed a sex difference， with meat in male patients and staple food in female patients； 64.1% of the patients with recurrence had a high-salt and high-oil diet； 59.8% of the patients had changes in diet after the first surgery for stones， among whom 80% were able to have a regular diet， and the patients with a regular diet accounted for 92%. ConclusionThere is a relatively low recurrence rate of primary common bile duct stones in this area， and there is no sex difference. The peak of recurrence is 10 years after surgery， and recurrence of stones is mainly observed in the population aged >60 years. The analysis of dietary and clinical features can help doctors and patients to further understand the characteristics of the recurrence of primary common bile duct stones and provide a basis for subsequent targeted prevention.

Objective:To analyze the efficacy and safety of nalbuphine for analgesia in patients with non-mechanical ventilation in intensive care unit (ICU).Methods:From December 2018 to August 2021, a multicenter randomized controlled clinical study was conducted to select non-mechanical ventilation patients with analgesic needs admitted to ICU of four hospitals in Henan Province and Guizhou Province. Patients were randomly assigned to nalbuphine group and fentanyl group. The nalbuphine group was given continuous infusion of nalbuphine [0.05~0.20 mg/(kg·h)], and the fentanyl group was given continuous infusion of fentanyl [0.5~2.0 μg/(kg·h)]. The analgesic target was critical-care pain observation tool (CPOT) score<2. The observation time was 48 hours. The primary endpoint was CPOT score, the secondary endpoints were Richmond agitation-sedation score (RASS), ICU length of stay, adverse events, and proportion of mechanical ventilation. The quantitative data of the two groups were compared by t test or Mann-Whitney U test. The enumeration data were compared by chi square test or Fisher exact probability method. The data at different time points between groups were compared by repeated measures analysis of variance. Results:A total of 210 patients were enrolled, including 105 patients in the nalbuphine group and 105 patients in the fentanyl group. There was no significant difference in baseline data between the two groups (all P>0.05). There was no significant difference in CPOT score between nalbuphine group and fentanyl group at each time point after medication ( P>0.05), the CPOT score of both groups at each time point after medication was significantly lower than that before medication, and the analgesic target could be achieved and maintained 2 hours after medication. There was no significant difference in RASS between the two groups at each time point after medication ( P>0.05), which was significantly lower than that before medication, and the target sedative effect was achieved 2 hours after medication. There was no significant difference in ICU length of stay between nalbuphine group and fentanyl group [5.0(4.0,7.5) d vs. 5.0(4.0,8.0) d, P=0.504]. The incidence of delirium, nausea and vomiting, abdominal distension, pruritus, vertigo and other adverse events in the nalbuphine group was lower than that in the fentanyl group (all P<0.05). There was no significant difference in the incidence of other adverse events such as deep sedation, hypotension and bradycardia between the two groups (all P>0.05). The incidence of respiratory depression in nalbuphine group was not significantly different from that in fentanyl group ( P>0.05), but the proportion of mechanical ventilation was significantly lower than that in the fentanyl group [1.9% (2/105) vs. 8.6%(9/105), P=0.030]. Conclusions:Nalbuphine could be used for analgesia in ICU patients with non-mechanical ventilation. The target analgesic effect could be achieved within 2 hours, and it had a certain sedative effect with a low incidence of adverse reactions.

Objective:To establish a predictive model for the progression of acute kidney injury (AKI) to stage 3 AKI (renal failure) in the intensive care unit (ICU), so as to assist physicians to make early and timely decisions on whether to intervene in advance.Methods:A retrospective analysis was conducted. Thirty-eight patients with AKI admitted to the intensive care medicine of the Third People's Hospital of Henan Province from January 2018 to May 2023 were enrolled. Patient data including acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) upon admission, serum creatinine (SCr), blood urea nitrogen (BUN), daily urine output during hospitalization, and the timing of continuous renal replacement therapy (CRRT) intervention were recorded. Based on clinically collected pathological data, standardized creatinine value ratio mean polynomial fitting models were established as the first criterion for judging the progression to stage 3 AKI after data cleansing, screening, and normalization. Additionally, standardized creatinine value ratio index fitting models were established as the second criterion for predicting progression to stage 3 AKI.Results:A total of 38 AKI patients were included, including 25 males and 13 females. The average age was (58.45±12.94) years old. The APACHEⅡ score was 24.13±4.17 at admission. The intervention node was (4.42±0.95) days. Using a dual regression model approach, statistical modeling was performed with a relatively small sample size of statistical data samples, yielding a scatter index non-linear regression model for standardized creatinine value ratio data relative to day " n", with y = 1.246?2 x1.164?9 and an R2 of 0.860?1, indicating reasonable statistical fitting. Additionally, a quadratic non-linear regression model was obtained for the mean standardized creatinine value ratio relative to day " n", with y = -0.260?6 x2+3.010?7 x-1.612 and an R2 of 0.998?9, indicating an excellent statistical fit. For example, using a baseline SCr value of 66 μmol/L for a healthy individual, the dual regression model predicted that the patient would progress to stage 3 AKI within 3-5 days. This prediction was consistent when applied to other early intervention renal injury patients. Conclusion:The established model effectively predicts the time interval of the progression of AKI to stage 3 AKI (renal failure), which assist intensive care physicians to intervene AKI as early as possible to prevent disease progression.

Objective:To analyze the histopathological characteristics of peri-implant soft tissue in re-constructed jaws and the changes after keratinized mucosa augmentation(KM A)with free gingival graft(FGG).Methods:Twenty patients were enrolled in this study.Five patients of them,who were perio-dontal and systemic healthy and referred for crown lengthening before restoration with healthy keratinized gingiva collected were enrolled as healthy controls.15 patients of them were with fibula or iliac bone flaps jaw reconstruction(10 with fibula flap and 5 with iliac flap),who were referred to FGG and implant exposures before restoration.Soft tissue was collected before FGG in reconstructed jaws,and in 5 patients(3 with fibula flap and 2 with iliac flap)8 weeks after FGG if a second surgery was conducted.Histologi-cal analysis with hematoxylin-eosin stain and immunological analysis to interlukin-1(IL-1),interlukin-6(IL-6)and tumor necrosis factor-α(TNF-α)were performed.Results:Thickness from the bottom of stratum basale to the top of stratum granulosum and thickness of keratinized layer in reconstructed jaws were significantly lower compared with that of natural healthy keratinized gingiva[0.27(0.20,0.30)mmvs.0.36(0.35,0.47)mm,P＜0.05;16.49(14.90,23.37)μm vs.26.37(24.12,31.53)μm,P＜0.05].In the reconstructed area,thickness from the bottom of stratum basale to the top of stra-tum granulosum increased after KMA with FGG[0.19(0.16,0.25)mm vs.0.38(0.25,0.39)mm,P=0.059]and the thickness of keratinized layer significantly increased after KMA with FGG[16.42(14.16,22.35)μm vs.28.57(27.16,29.14)μm,P＜0.05],which was similar to that in the con-trol group.Furthermore,the number of positive cells of IL-1,IL-6 and TNF-α significantly increased after KMA[0.67(0.17,8.93)vs.11.00(9.16,18.00);13.00(8.50,14.14)vs.21.89(15.00,28.12);0.22(0.04,0.63)vs.2.83(1.68,5.00),respectively,P＜0.05]as well as the average optical density value[0.15(0.14,0.17)vs.0.18(0.17,0.21);0.28(0.26,0.33)vs.0.36(0.33,0.37);0.23(0.22,0.29)vs.0.30(0.28,0.42),respectively,P＜0.05],which was similar to that in the healthy keratinized gingiva.Conclusion:The lack of rete pegs and inflammato-ry factors were common in soft tissue with jaw reconstruction.FGG can improve the quality of the epithe-lium and may improve the stability of the mucosa around implants.

Objective:To analyze the concentration of formic acid,propionic acid and butyric acid in gingival crevicular fluid(GCF)of patients with stages Ⅲ and Ⅳ periodontitis,and their relationship with periodontitis.Methods:The study enrolled 37 systemically healthy patients with periodontitis and 19 healthy controls who visited Department of Periodontology,Peking University School and Hospital of Sto-matology from February 2008 to May 2011.Their GCFs were collected from the mesial-buccal site of one molar or incisor in each quadrant.Periodontal clinical parameters,including plaque index(PLI),probing depth(PD),bleeding index(BI),and attachment loss(AL).Concentrations of formic acid,propionic acid and butyric acid in the supernatant of the GCFs were analyzed by high-performance capil-lary electrophoresis(HPCE).The prediction ability of formic acid,propionic acid and butyric acid with the risk of periodontitis and the differences between grade B and grade C periodontitis were analyzed.Results:In this study,32 patients with stage Ⅲ and 5 patients with stage Ⅳ were enrolled,including 9 patients with grade B and 28 patients with grade C.Clinical periodontal variables in the patients with pe-riodontitis were significantly higher than those in the control group(P＜0.001).Formic acid was signifi-cantly lower in periodontitis than that in the control group[5.37(3.39,8.49)mmol/L vs.12.29(8.35,16.57)mmol/L,P＜0.001].Propionic acid and butyric acid in periodontitis were significantly higher than those in the control group:Propionic acid,10.23(4.28,14.90)mmol/L vs.2.71(0.00,4.25)mmol/L,P＜0.001;butyric acid,2.63(0.47,3.81)mmol/L vs.0.00(0.00,0.24)mmol/L,P＜0.001.There was no significant difference in formic acid,propionic acid and butyric acid concentrations between grade B and grade C periodontitis(P＞0.05).Propionic acid and butyric acid in the deep pocket were significantly higher than in the shallow pocket,while the concentration of formic acid decreased with the increase of PD.Propionic acid(OR=1.51,95％CI:1.29-1.75)and butyric acid(OR=3.72,95％CI:1.93-7.17)were risk factors for periodontitis,while formic acid(OR=0.87,95％CI:0.81-0.93)might be a protective factor for periodontitis.Propionic acid(AUC=0.852,95％CI:0.805-0.900),butyric acid(AUC=0.889,95％CI:0.841-0.937),f(formic acid,AUC=0.844,95％CI:0.793-0.895)demonstrated a good predictive capacity for the risk of periodontitis.Conclusion:The concentration of formic acid decrease in the GCF of periodontitis patients,which is a protective factor for periodontitis,its reciprocal have good predictive capacity.However,propionic acid and butyric acid increase,which are risk factors for periodontitis and have good predictive capacity.The concentration of formic acid,propionic acid,and butyric acid vary with probing depth,but there is no significant difference between grade B and grade C periodontitis.

Objective: To determine the active components of Eupolyphaga sinensis Walker (Tu Bie Chong) and explore the mechanisms underlying its fracture-healing ability. Methods: A modified Einhorn method was used to develop a rat tibial fracture model. Progression of bone healing was assessed using radiological methods. Safranin O/fast green and CD31 immunohistochemical staining were performed to evaluate the growth of bone cells and angiogenesis at the fracture site. Methylthiazoletetrazolium blue and wound healing assays were used to analyze cell viability and migration. The Transwell assay was used to explore the invasion capacity of the cells. Tubule formation assays were used to assess the angiogenesis capacity of human vascular endothelial cells (HUVECs). qRT-PCR was used to evaluate the changes in gene transcription levels. Results: Tu Bie Chong fraction 3 (TF3) significantly shortened the fracture healing time in model rats. X-ray results showed that on day 14, fracture healing in the TF3 treatment group was significantly better than that in the control group (P = .0086). Tissue staining showed that cartilage growth and the number of H-shaped blood vessels at the fracture site of the TF3 treatment group were better than those of the control group. In vitro, TF3 significantly promoted the proliferation and wound healing of MC3T3-E1s and HUVECs (all P < .01). Transwell assays showed that TF3 promoted the migration of HUVECs, but inhibited the migration of MC3T3-E1 cells. Tubule formation experiments confirmed that TF3 markedly promoted the ability of vascular endothelial cells to form microtubules. Gene expression analysis revealed that TF3 significantly promoted the expression of VEGFA, SPOCD1, NGF, and NGFR in HUVECs. In MC3T3-E1 cells, the transcript levels of RUNX2 and COL2A1 were significantly elevated following TF3 treatment. Conclusion TF3 promotes fracture healing by promoting bone regeneration associated with the RUNX2 pathway and angiogenesis associated with the VEGFA pathway.

Objective To explore effect of Wenyang Qudu formula on serum inflammatory factors and immune index in patients with severe infections.Methods A total of 86 severe infection patients admitted to the Third People's Hospital of Henan Province from January to December 2023 were selected as the research subjects.According to the patient file order,odd numbers were the study group,and even numbers were the control group,with 43 cases in each group.The control group was treated with cefoperazone sulbactam sodium,while the study group was treated with Wenyang Qudu formula in addition to the control group[drug composition:Prepared aconite(first decocted)30 g,Poria cocos 30 g,White peony 15 g,Red peony 15 g,Stir fried atractylodes macrocephala 30 g,Dried ginger 9 g,Roasted licorice 9 g,Cassia twig 15 g,Semen lepidii 15 g,Dragon's bone 15 g,Raw oyster 15 g,Codonopsis pilosula 12 g,Angelica sinensis 12 g,Asarum 3 g,Schisandra chinensis 6 g,and Jujube 12 g].Brew in water,and took one dose daily,once in the morning and once in the evening,for a continuous period of 7 days.The differences in the scores of traditional Chinese medicine symptoms such as fever,dyspnea,frequent urination,urgency,and degree of sputum production,serum levels of interleukin-10(IL-10),C-reactive protein(CRP),eosinophils(EOS),and immune function indicators[immunoglobulin E(IgE),CD3+,CD4+,CD8+,CD4+/CD8+]were compared between two groups after treatment,and observed the occurrence of adverse reactions.Results After treatment,the traditional Chinese medicine symptom scores(fever,dyspnea,frequent urination and urgency,degree of sputum production),as well as IL-10,CRP,EOS levels,IgE,and CD8+ were significantly reduced in both groups compared to before treatment,CD3+,CD4+,and CD4+/CD8+ were significantly increased compared to before treatment.In addition,the study group had significantly lower scores of fever,dyspnea,frequent urination and urgency,degree of sputum production,IL-10,CRP,EOS levels,IgE,and CD8+ compared to the control group(fever score:1.36±0.30 vs.2.57±0.46,dyspnea score:1.22±0.31 vs.2.26±0.75,urinary frequency and urgency score:1.30±0.39 vs.2.33±0.82,degree of sputum production:1.19±0.77 vs.2.51±0.85,IL-10(ng/L):9.03±1.67 vs.10.51±2.40,CRP(mg/L):4.68±1.33 vs.7.82±2.53,EOS(×109/L):0.30±0.04 vs.0.46±0.10,IgE(mg/L):104.62±10.73 vs.135.68±14.64,CD8+:0.228±0.016 vs.0.258±0.020,all P<0.05],the levels of CD3+,CD4+,and CD4+/CD8+ were significantly higher than those in the control group(CD3+:0.636±0.044 vs.0.567±0.055,CD4+:0.537±0.054 vs.0.397±0.045,CD4+/CD8+:1.76±0.51 vs.0.55±0.39,all P<0.05].After treatment,it was discovered that the study group had not experienced any adverse reactions,while the control group had 1 case of nausea and vomiting and 1 case of chest tightness.There was no statistically significant difference in the incidence of adverse reactions between the study group and the control group[0(0/43)vs.0.05%(2/43),P>0.05].Conclusion The Wenyang Qudu formula can reduce the serum factor levels of IL-10,CRP,and EOS in critically infected patients,and improve immune function with good safety.

We conducted a prospective study to assess the non-inferiority of adjuvant chemotherapy alone versus adjuvant concurrent chemoradiotherapy (CCRT) as an alternative strategy for patients with early-stage (FIGO 2009 stage IB-IIA) cervical cancer having risk factors after surgery. The condition was assessed in terms of prognosis, adverse effects, and quality of life. This randomized trial involved nine centers across China. Eligible patients were randomized to receive adjuvant chemotherapy or CCRT after surgery. The primary end-point was progression-free survival (PFS). From December 2012 to December 2014, 337 patients were subjected to randomization. Final analysis included 329 patients, including 165 in the adjuvant chemotherapy group and 164 in the adjuvant CCRT group. The median follow-up was 72.1 months. The three-year PFS rates were both 91.9%, and the five-year OS was 90.6% versus 90.0% in adjuvant chemotherapy and CCRT groups, respectively. No significant differences were observed in the PFS or OS between groups. The adjusted HR for PFS was 0.854 (95% confidence interval 0.415-1.757; P = 0.667) favoring adjuvant chemotherapy, excluding the predefined non-inferiority boundary of 1.9. The chemotherapy group showed a tendency toward good quality of life. In comparison with post-operative adjuvant CCRT, adjuvant chemotherapy treatment showed non-inferior efficacy in patients with early-stage cervical cancer having pathological risk factors. Adjuvant chemotherapy alone is a favorable alternative post-operative treatment.

The reconstruction effect of peri-implantitis bone defects depends on their morphological characteristics. This paper reviews the morphological classification and treatment of peri-implantitis bone defects. A literature review shows that the morphological classification of bone defects in peri-implantitis includes morphology classification and clinical classification. At present, the Renvert classification is more commonly used in the clinic and is divided into four-wall bone pockets, three-wall bone pockets, two-wall bone pockets, one-wall bone pocket and dehiscence according to the number of bone walls. This has guiding significance in the treatment plan of peri-implantitis. The treatment of peri-implantitis depends on the severity of peri-implant bone defects. Peri-implantitis with mild bone defects is treated by nonsurgical treatment, peri-implantitis with severe bone defects is recommended to remove the implant, and peri-implantitis with moderate bone defects is further judged according to the shape of the bone defects. Four-wall bone pockets, three-wall bone pockets and dehiscence are mostly treated by bone regenerative surgery. For shallow two-wall bone pockets, one-wall bone pockets and horizontal bone resorption, bone resection is often used. However, most peri-implantitis has a variety of bone defect forms at the same time, which need to be treated with bone regenerative surgery and bone resection surgery.

A male patient aged 1 year and 8 months with type 2 spondyloepimetaphyseal dysplasia with joint laxity (SEMDJL2) was reported. The clinical characteristics included short stature, flat middle face, hypotonia, limb joint relaxation, hyperextension of metacarpophalangeal articulation, etc. In addition, the patient had a history of congenital laryngeal stridor. Thus, SEMDJL2 was determined according to the above symptoms and medical history. Sanger sequencing showed that the child carried a c.443C>T missense mutation in the KIF22 gene, which resulted in an amino acid variation namely p.Pro148Leu. This phenotype was preliminarily determined as a pathogenic mutation. Therefore, it is suggested that next-generation sequencing genetic testing could be helpful for genetic diagnosis in children with congenital laryngeal stridor, systemic joint relaxation, and excessive joint extension.
