OBJECTIVE To provide reference for improving the working efficiency of prescription review for pharmacists and ensuring the safe use of parenteral nutrition solution in patients.　METHODS The review module of parenteral nutrition prescription was developed with the pharmacy intravenous admixture services（PIVAS） MATE system. According to the instructions and relevant information of parenteral nutrition solution， the parameters to the review module for parenteral nutrition solution prescriptions were assigned， thresholds and calculation formulas were set， and the prescription was automatically determined by the system. The type and quantity of the inappropriate prescriptions of parenteral nutrition solution in our hospital from January to August 2020 and from January to August 2022 were counted， and the review efficiency of inappropriate prescriptions was compared before and after the application of the review module of parenteral nutrition solution prescription.　RESULTS The module realized the informatized review of basic attribute parameters and custom parameters of parenteral nutrition solution prescription， such as ion concentration， ratio of heat to nitrogen， ratio of sugar to lipid， glucose concentration， ratio of sugar to insulin， maximum dosage of compound preparation， necessary drug collocation， incompatibility， repeated drug use， age limit， etc. The module also shortened the review time greatly. It took about 33 minutes for two pharmacists to review 100 prescriptions， and only took 6 seconds after the module went online. Compared with January to August in 2020， the average approval rate of inappropriate prescriptions for parenteral nutrition solution increased from 0.582% to 1.416% during the corresponding period in 2022 （P＜0.05）.　CONCLUSIONS The review module of parenteral nutrition solution prescription established by parameter assignment method in our hospital can greatly reduce the phenomenon of missed and wrong review by pharmacists， reduce the risk of parenteral nutrition solution dispensing， reduces the work pressure of pharmacists reviewing prescriptions， and ensures the drug safety of patients.

Objective:To evaluate the strategy and skills of reoperation for recurrent carcinoma at the stoma of esophagojejunostomy after total gastrectomy.Methods:The management experience in 18 patients at the Department of General Surgery, Tumor Hospital of Zhengzhou University from Oct 2016 to Jul 2021 were analyzed retrospectively.Results:Thirteen patients underwent left thoracoabdominal combined incision to completely remove the tumor.One patient developed anastomotic leakage, two patients developed pulmonary infection, one patient developed costochondritis, all were cured and discharged after conservative treatment; Nine patients had no postoperative complications. Two patients abandoned surgery due to high position of the tumor, 3 patients due to poor cardiopulmonary function, and were given radiotherapy and chemotherapy.The postoperative follow-up period was 4.6 to 42.9 months. Four patients died of tumor recurrence, and the remaining patients survived until the end of the follow-up. The overall 1-and 3-year recurrence-free survival rates were 100% and 20%, respectively.Conclusion:Surgery on recurrent carcinoma at esophagojejunostomy stoma after total gastrectomy, although difficult and challenging,could still benefit most patients when at the hands of expertise.

Objective:To observe and analyze the clinical characteristics of children who died of intraocular retinoblastoma (RB).Methods:A retrospective clinical study. Fourteen children (23 eyes) with intraocular RB who died after receiving treatment in Beijing Children's Hospital from 2009 to 2017 were included in the study. Among the children, there were 7 males (10 eyes) and 7 females (13 eyes); 5 had unilateral and 9 had bilateral tumor. Age were 17.2±15.5 months. All children underwent RetCam examination. RB was staged according to the international intraocular RB classify. Among the 23 eyes, 1 eye was in stage B, 2 eyes were in stage C, 12 eyes in stage D, and 8 eyes in stage E. Treatment methods included a systemic (vincristine, etoposide and carboplatin) chemotherapy (VEC chemotherapy), enucleation surgery, and vitrectomy. The basic conditions including age, time of diagnosis, pathological diagnosis, treatment and main causes of death were retrospectively analyzed.Results:Among the 14 cases, the first symptom was leukemia in 12 cases, red eye in 1 case, and squintin in 1 case. Systemic VEC chemotherapy was used for 1-6 courses of treatment; 5 cases were enucleated, 3 cases underwent histopathological examination; 3 cases were treated with vitrectomy. Among the 3 cases who underwent histopathological examination, the sclera and optic nerve, optic nerve and optic disc were invasted respectively. Seven patients died of tumor metastasis and/or intracranial lesions (50.0%, 7/14); the median survival time was 19 months. Four patients died of treatment (28.6%, 4/14), including 3 patients died of chemotherapy-related side effects, and 1 died of organ failure after enucleation surgery (7.1%); the median survival time was 3.5 months. Early abandonment of treatment died in 3 cases (21.4%, 3/14); the median survival time was 15 months.Conclusion:Intracranial metastasis is the main cause of death in children with intraocular RB.

Objective:To investigate the effect of Suhuang Zhike Capsule on airway inflammation in patients with acute episode of allergic rhinitis and asthma syndrome.Methods:Eighty patients with allergic rhinitis and asthma syndrome were admitted to North China University of Science and Technology Affiliated Hospital from June 2016 to September 2017.A prospective cohort study was carried out and randomly divided into treatment group and control group with 40 patients in each group.The control group was treated with conventional anti-inflammatory, expectorant and antiasthmatic therapy, while the treatment group was treated with Suhuang Zhike Capsule.The changes of nasal symptoms and asthma clinical symptoms in the two groups were compared before and after treatment, and the changes of nitric oxide in exhaled air, eosinophils in blood and induced sputum were measured.Results:Compared with the control group, there was no significant difference in the number of eosinophils in the exhaled nitric oxide, eosinophil count in blood and induced sputum before treatment in the treatment group ((161.45±4.67)×10 -9 vs.(163.12±4.56)×10 -9, (1.59±0.53)×10 9/L vs.(1.60±0.51)×10 9/L, (1.11±0.06)×10 9/L vs.(1.18±0.09)×10 9/L; t values were 0.10, 0.44, 1.75, respectively, all P>0.05). After treatment, the exhaled nitric oxide, eosinophil count in blood and induced sputum in the treatment group were significantly lower than those before treatment((30.86±5.54)×10 -9 vs. (161.45±4.67)×10 -9; (0.32±0.05)×10 9/L vs. (1.59±0.53)×10 9/L; (0.06±0.02)×10 9/L vs. (1.11±0.06)×10 9/L, t values were 91.32, 41.63, 51.77, respectively, all P<0.01). In the treatment group, the effective rate of nasal symptom control was 85.0% (34/40) significantly higher than 62.5% (25/40) in the control group (χ 2=5.23, P<0.05), and the effective rate of asthma clinical symptom control was significantly higher than that in the control group(90.0%(36/40), 72.5%(29/40), χ 2=4.02, P<0.05). Conclusion:Suhuang Zhike capsule can obviously improve the airway inflammatory response of patients with allergic rhinitis asthma syndrome in the acute attack stage, and the combination of conventional treatment plan is helpful to improve the curative effect.

Objective:To investigate the optimal experimental conditions (including antigen retrieval time, antibody titers and antibody incubation time) for reliable detection of programmed death-ligand 1 (PD-L1) expression using PD-L1 (22C3) antibody concentrate, and to establish a laboratory developed test for PD-L1 detection.Methods:Using Dako PD-L1 IHC 22C3 pharmDX staining procedure and scoring guidelines as the standard reference (group A), the PD-L1 expression in 25 tissue specimens (including 15 lung cancer tissues, 5 tonsil tissues and 5 placenta tissues) was detected with Flex+/HRP detection kit (EnVision) under 8 different experimental conditions (groups B1 to B8). The staining results were then compared to those in group A.Results:In group B1, 3 tissue samples showed the percentages of PD-L1 positive tumor cells were similar to those in group A, while the percentages of PD-L1 positive tumor cells were lower than those in group A in the other samples. In group B7, two case showed a positive rate higher than that in group A that was also above the positive cut-off value, and the rest of the samples had a percentage of PD-L1 positive tumor cells slightly higher than that in group A, but still below the positive cut-off value. The staining results of group B8 were the closest to those of group A compared with the other groups. Although the percentages of PD-L1 positive tumor cells in the B2 to B6 groups were decreased in various degrees as compared with group A, they were still concordant with group A′s classification (positive vs. negative) and would not change the choice of clinical treatments.Conclusions:The experimental conditions are associated with detection rate of PD-L1 expression using 22C3 antibody. In the present study, the most-suitable alterative conditions in the PD-L1 detection using 22C3 antibody concentrate are those applied in the group B8 (including antigen retrieval in Dako PT Link tank at 97 ℃, pH 6.0 for 40 min and incubation with 22C3 antibodies (1∶100 dilution) at room temperature for 60 min, incubation with EnVision Flex+Linker at room temperature for 30 min, incubation with EnVision/HRP at room temperature for 30 min and DAB staining for 5 min), which could provide reliable results at minimum costs.

Objective:To study the clinicopathological characteristics and pathologic diagnosis of autoimmune gastritis.Methods:Fourteen biopsies of autoimmune gastritis were collected from January 2018 to March 2019 at Guangdong Provincial People′s Hospital. Their clinical data, histological features and immunohistochemical (IHC) results were analyzed, with review of relevant literature.Results:All 14 patients′ ages ranged from 41 to 79 years (mean 55 years). There were 12 females and 2 males. All patients had non-specific symptoms, but they all had positive serum anti-parietal cell antibody and/or anti-intrinsic factor antibody. Seven patients had variable degree of anemia. Two patients had concomitant H. pylori infection. Two patients presented with multiple protruding polyps in corpus/fundus, 0.2 to 0.9 cm in diameter, or multiple large lobulated and broad based polyps (0.8 to 3.5 cm in diameters). The former cases were diagnosed as type 1 neuroendocrine tumors, the latter were multiple hyperplastic polyps. Microscopically, autoimmune gastritis showed typical morphology, characterized by diffuse corpus-restricted atrophic gastritis with variable proportions of intestinal metaplasia, or pseudopyloric metaplasia, pancreatic, acinar metaplasia, foveolar hyperplasia and hyperplasia of the endocrine-like cells (ECL cells). Hyperplasia of ECL cells often needed IHC staining to confirm. CgA/Syn IHC stain highlighted linear and micronodular ECL cell hyperplasia. In the absence of concurrent or past H. pylori infection, the antrum was usually normal. Gastrin IHC stain showed hyperplasia of gastrin-producing cells (G cells) in the antrum. Two cases were in the early phase, six were in florid phase, and six were end phase.Conclusions:Most patients of autoimmune gastritis have non-specific symptoms or are asymptomatic and show various endoscopic findings. There are three histologic phases of autoimmune gastritis. Recognition of this entity would be beneficial for pathologists to avoid misdiagnosis. Pathologists can make preferred diagnosis of autoimmune gastritis depending on the histologic clues and prompt appropriate and timely management for the patients.

Objective: To evaluate the efficacy of articular compression molding techniques in the surgery for acetabular posterior wall fracture. Methods: A retrospective study was conducted of the 28 patients (28 hips) with fracture of acetabular posterior wall plus comminuted compression of articular surface who had been treated using the articular compression molding techniques at Department of Orthopedics, The Hospital of 81 Group Army of PLA from January 2014 to January 2018. They were 25 males and 3 females, aged from 26 to 63 years (average, 49.3 years). The time from injury to surgery ranged from 4 to 12 days (average, 7.8 days). According to the Letournel-Judet classification, all were single element (simple) posterior wall fractures combined with posterior dislocation of the femoral head and articular compression of different degrees; transient sciatic nerve injury was complicated in 12 cases. The posterior hip dislocations were timely and successful reset at emergency treatment. The compression fractures of the posterior wall and hip joint were treated by open reduction and internal fixation via the acetabular posterior (K-L) approach. The articular compression was treated by 4 stabilization techniques: absorbable screwing and blocking technique in 10 cases, indwelling screwing in 12 cases, indwelling Kirschner wiring in 2 cases and die push and squeeze tamping in 4 cases. The operation time, intraoperative bleeding and complications were recorded. The therapeutic efficacy was evaluated by the modified Merle d’Aubigne & Postel scoring criteria at the final follow-up. Results: The operation time lasted from 76 to 118 minutes (average, 94.2 minutes); the intraoperative bleeding ranged from 100 to 320 mL (average,220.8 mL). No incision liquefaction, infection or other complications occurred. The 28 patients were followed up for 10 to 36 months (average, 17.6 months). According to the Matta scoring criteria, 24 cases achieved anatomical reduction but 4 dissatisfactory reduction. By the modified Merle d’Aubigne & Postel scoring criteria at the final follow-up, the efficacy was evaluated as excellent in 26 cases and as good in 2. Heterotopic ossification was observed in 3 cases and microscopic free dense shadow in the joint cavity (about 2 mm in the round ligament) in 3 cases. There were no cases of obvious traumatic arthritis or osteoarthritis, femoral head necrosis, walking pain, lameness or hip abduction weakness. The 12 patients complicated with preoperative transient sciatic nerve injury recovered within 3 months after surgery. Conclusion The articular compression molding techniques can effectively treat severely comminuted articular compression in the acetabular posterior wall fracture and improve reduction of articular surface and hip joint matching, leading to stability and good joint function.

Objective: To study the clinicopathological characteristics, immunophenotype, pathologic diagnosis and differential diagnosis of diffuse pulmonary meningotheliomatosis (DPM). Methods: The clinical data, histological features and immunohistochemical results of three cases of DPM collected from January 2016 to May 2018 at Guangdong Provincial People′s Hospital were analyzed, and the relevant literature reviewed. Results: The three DPM patients age was 53, 69 and 74 years. The lesions consisted of multiple minute pulmonary meningothelial-like nodules profusely involving the lungs. Microscopically, they showed typical morphology, characterized by medium-sized elongated tumor cells resembling meningothelial cells with whorled/nested clusters. The cells were uniform and had abundant eosinophilic cytoplasm with oval nuclei with delicate chromatin. Immunohistochemical staining showed tumor cells were diffusely and strongly positive for EMA, vimentin and PR, but were negative for CAM5.2, CgA, Syn, CK7 and TTF1. Conclusions DPM is extremely rare, and may be confused with primary interstitial pulmonary processes and metastatic malignant tumors of lung. Recognition of this entity is essential for pathologists to avoid misdiagnosis and unnecessary treatment.
