Haematitum and Limonitum are two iron-containing mineral medicines included in the 2020 edition of the Chinese Pharmacopoeia. They have similar main components and major differences in their property, flavor, channel tropism, and clinical uses. In this study, we investigated the surface properties, mineral composition, mineral dissociation, elemental composition, and iron state of Haematitum and Limonitum to explore their mineralogical differences. Scanning electron microscopy(SEM), specific surface and porosity analyzer, X-ray diffractometer(XRD), X-ray photoelectron spectrometer(XPS), and advanced mineral identification and characterization system(AMICS) were used to analyze the mineralogy of Haematitum and Limonitum. The results showed that Haematitum had an angular surface with granular attachments and a specific surface area of 17.04 m~2·g~(-1). In comparison, Limonitum had a smooth and flat surface with a bundled acicular crystal structure and a specific surface area of 46.29 m~2·g~(-1). Haematitum consists of 31 detectable minerals containing 18 elements, with the major element, iron(44.5% Fe~(2+) and 55.5% Fe~(3+)) distributed in 17 minerals, including hematite, iron oxide, knebelite, siderite, and magnesioferrite. Limonitum consists of 32 detectable minerals containing 17 elements, with the major element, iron(14.5% Fe~(2+) and 85.5% Fe~(3+)) distributed in 19 minerals, including limonite, iron oxide, chlorite, and knebelite. In summary, the elemental composition of Haematitum and Limonitum does not differ greatly, but there are large differences in the mineral composition and iron state. The large specific surface area and strong adsorption capacity of Limonitum may be one of the mechanisms of its anti-diarrheal action. The Fe_2O_3 and illite contained in Haematitum and Limonitum may be the key substances for their hemostasis effects. The mineralogical differences are expected to provide a reference for explaining the scientific connotation of mineral medicine and laying a material foundation for studying its mechanism of action.

OBJECTIVE: To explore clinical efficacy of membrane-induced technique combined with gastrocnemius muscle flap transposition in treating traumatic osteomyelitis of the upper tibia. METHODS: A retrospective analysis was conducted on 7 patients with traumatic osteomyelitis of the upper tibia who were treated with membrane-induced technique combined with gastrocnemius muscle flap transposition from January 2022 to December 2023. Among them, there were 4 males and 3 females; aged from 29 to 57 years old; 4 patients were treated after open fracture, 2 patients were treated after closed fracture, and 1 patient was treated after scalding; the courses of disease ranges from 2 weeks to 8 years; sinus tracts were present in all patients, and the lesion range of the tibia ranged from 5 to 9 cm. The results of deep tissue bacterial culture showed that 2 patients were negative, 3 patients were staphylococcus aureus, 1 patient was methicillin-resistant staphylococcus aureus, and 1 patient was pseudomonas aeruginosa and 1 patient was klebsiella pneumoniae. After debridement, the range of bone defect ranged from 8 to 12 cm, and the cortical defect accounted for approximately 30% of the circumference. The area of soft tissue defect ranged from 8.0 cm×2.0 cm to 10.0 cm×6.0 cm. At the first stage, vancomycin-loaded/meropenem/gentamicin-loaded bone cement was implanted. The gastrocnemius muscle flap was repositioned to cover the wound surface and free skin grafting was performed. After an interval of 7 to 10 weeks, the stageⅡsurgery was performed to remove bone cement. Autologous iliac bone mixed with vancomycin/gentamicin and calcium sulfate artificial bone was transplanted, and the wound was sutured. One patient retained the original internal plants, one patient removed the internal plants and replaced them with steel plate external fixation, one patient replaced the internal plants and added steel plate external fixation, and three patients were simply fixed with steel plate external fixation. One year after operation, the recovery of knee joint and ankle joint functions was evaluated by using Hospital for Special Surgery (HSS) knee joint score and Kofoed ankle joint function score respectively. RESULTS: All patients had their wounds closed simultaneously with bone cement implantation and healed well. All patients were followed up for 12 to 17 months after operation, and satisfactory bone healing was achieved at 6 months after stageⅡsurgery. Twelve months after operation, all patients had good bone healing without obvious limping was observed when walking. At 12 months after operation HSS knee joint score ranged from 93 to 100 points, and Kofoed ankle function score ranged from 96 to 100 points. CONCLUSION For traumatic osteomyelitis of the upper tibia, a staged treatment plan combining membrane-induced technique and gastrocnemius flap transposition on the basis of thorough debridement could safely cover the wound surface, effectively control bone infection and achieve satisfactory bone healing, without adverse effects on limb function.

OBJECTIVES: To investigate the clinical features of children with STAT gene mutations, and to explore corresponding immunotherapy strategies. METHODS: A retrospective analysis was performed for the clinical data of 10 children with STAT gene mutations who were admitted to the Department of Pediatrics of the First Affiliated Hospital of Guangzhou Medical University, from October 2015 to October 2024. Exploratory immunotherapy was implemented in some refractory cases, and the changes in symptoms, imaging manifestations, and cytokine levels were assessed after treatment. RESULTS: For the 10 children, the main clinical manifestations were recurrent rash since birth (7/10), cough (8/10), wheezing (5/10), expectoration (4/10), and purulent nasal discharge (4/10). Genotyping results showed that there was one child with heterozygous loss-of-function (LOF) mutation in the STAT1 gene, four children with heterozygous LOF mutation in the STAT3 gene, and five children with heterozygous gain-of-function (GOF) mutation in the STAT3 gene. Two children with LOF mutation in the STAT3 gene showed decreased interleukin-6 levels and improved clinical symptoms and imaging findings after omalizumab treatment. Three children with GOF mutation in the STAT3 gene achieved effective disease control after treatment with methylprednisolone (0.5 mg/kg per day). Two children with GOF mutation in the STAT3 gene received treatment with JAK inhibitor and then showed some improvement in symptoms. CONCLUSIONS STAT gene mutation screening should be considered for children with recurrent rash and purulent respiratory tract infections. Targeted immunotherapy may improve prognosis in patients with no response to conventional treatment.

Objective:To explore the application value of right-opening single flap valvuloplasty based on tubular stomach in gastrointestinal reconstruction after laparoscopic proximal gastrectomy.Method:Use a linear cutting stapler to make a parallel curve from the angle of the stomach to the junction of the gastric fundus to remove the lesser curvature of the stomach, and detach the gastric body about 5 cm away from the tumor to create a tubular stomach. Use a marker pen to draw a C-shaped seromuscular flap area with a width of 2.5 cm and a height of 3.5 cm 1.5 cm below the residual stomach closure nail, and create a free muscle flap in the gap between the plasma muscle layer and the submucosal layer. Make a transverse incision of 3 cm at the lower edge of the mucosal bed, and intermittently suture the entire lower edge of the gastric wall with 3 stitches. Under laparoscopy, use 4-0 barbed wire to suture the 1 cm wide muscular layer at the top of the tubular stomach and the posterior wall of the esophagus about 5 cm away from the esophageal stump with 3 stitches. Push the upper end of the tubular stomach into the mediastinum, and then tighten the barbed wire to ensure a tight fit between the stomach and the posterior wall of the esophagus. Use an ultrasonic scalpel to remove the esophageal stump, suture the entire posterior wall of the esophagus with the gastric mucosa, and use barbed wire to suture the anterior wall from left to right. The anastomotic site is completely covered with a free muscle flap, and the barbed line is used to continuously suture the muscle flap along the C-shaped line to the gastric pulp muscle layer at the edge of the mucosal bed, embedding the anastomotic site and completing the reconstruction of the digestive tract.Results:Clinical data of 23 patients (18 from the First Affiliated Hospital of Wenzhou Medical University and 5 from the Quzhou Hospital affiliated with Wenzhou Medical University) who underwent laparoscopic proximal gastrectomy, tubular gastroesophageal anastomosis, and pure manual right flap reconstruction surgery for esophagogastric junction adenocarcinoma and proximal gastric cancer from October 2023 to August 2024. There were 15 males and 8 females, with an age of (65.3±7.7) years, the BMI was (22.9±2.8) kg/m 2. All patients in the group successfully completed the surgery, with a surgery time of (218.5±38.1) minutes, including (73.5±19.2) minutes for anastomosis, intraoperative blood loss of (64.5±15.4) ml, postoperative passage of gas on (3.4±0.5) days, first consumption of liquid food after surgery of (3.9±1.1) days, and postoperative hospital stay of (9.1±0.8) days. One patient developed anastomotic stenosis (grade I) after surgery, presenting with mild swallowing obstruction, which returned to normal after dietary adjustment, and there were no cases of secondary surgery. The median follow-up time for the entire group was 4.0 (0.7-7.0) months, during which there were no deaths or tumor recurrence or metastasis, no complications such as anastomotic stenosis or gastric emptying disorders, and no complaints of acid reflux or heartburn. At one month of postoperative follow-up, the reflux symptom index (RSI) score was (3.1±2.9) points, and at three months, the RSI score was (2.4±1.4) points. Conclusions:The application of right-opening single flap valvuloplasty based on tubular stomach for gastrointestinal reconstruction after laparoscopic proximal gastrectomy is safe,feasible,and has satisfactory short-term efficacy.
