OBJECTIVE To explore the role of clinical pharmacists participating in the standardized perioperative nutritional management process for pancreaticoduodenectomy （PD） on improving postoperative recovery in patients. METHODS The clinical data of 100 patients undergoing PD in the Department of Biliary and Pancreatic Surgery， Drum Tower Hospital Affiliated to Nanjing University School of Medicine from November 2019 to February 2021 were analyzed retrospectively. According to the different perioperative nutrition management plans， they were divided into clinical pharmacist intervention group （n＝51， clinical pharmacists intervened according to the standardized nutrition management process） and control group （n＝49， clinical pharmacists only performed preoperative nutrition evaluation， and clinical physicians took nutrition support according to the patient’s condition）. The differences in postoperative recovery index， economic evaluation index， hospitalization length， postoperative complications， and postoperative enteral nutrition support route were compared between 2 groups. RESULTS The time of postoperative diet， the first postoperative ventilation， the first postoperative defecation， and postoperative drainage time of abdominal drain were significantly earlier in the clinical pharmacist intervention group than in the control group （P＜0.05）； the hospitalization cost， medication cost， nutritional support cost， parenteral nutrition cost， albumin preparation cost， and the length of postoperative hospitalization were significantly lower/shorter in the clinical pharmacist intervention group than in the control group （P＜0.05）； there was no statistically significant difference in the incidence of postoperative complications between the two groups （P＞0.05）； there was statistically significant difference in the perioperative enteral nutrition support pathways between two groups （P＜0.05）. CONCLUSIONS Clinical pharmacists’ participation in perioperative nutritional management for PD can significantly reduce hospitalization costs and nutritional support costs， improve patients’ perioperative nutritional status， and shorten hospital stays. wanglina668@163.com

Objective Aberrant expression of ATP binding cassette subfamily B member 1(ABCB1)plays a key role in several cancers.However,influence of G protein coupled receptor family C group 5 type A(GPRC5A)-regulated ABCB1 expression on lung adenocarcinoma proliferation remains unclear.Therefore,this study investigated the effect of GPRC5A regulated ABCB1 expression on the proliferation of lung adenocarcinoma. Methods ABCB1 expressions in lung adenocarcinoma cell lines,human lung adenocarcinoma tissues,and tracheal epithelial cells and lung tissues of GPRC5A knockout mice and wild-type mice were analyzed with RT-PCR,Western blot,or immunohistochemical analysis.Cell counting kit-8 assay was performed to analyze the sensitivity of tracheal epithelial cells from GPRC5A knockout mice to chemotherapeutic agents.Subcutaneous tumor formation assay was performed to confirm whether down-regulation of ABCB 1 could inhibit the proliferation of lung adenocarcinoma in vivo.To verify the potential regulatory relationship between GPRC5A and ABCB1,immunofluorescence and immunoprecipitation assays were performed. Results ABCB1 expression was up-regulated in lung adenocarcinoma cell lines and human lung adenocarcinoma tissues.ABCB1 expression in the tracheal epithelial cells and lung tissues of GPRC5A deficient mice was higher than that in the wild type mice.Tracheal epithelial cells of GPRC5A knockout mice were much more sensitive to tariquidar and doxorubicin than those of GPRC5A wild type mice.Accordingly,28 days after injection of the transplanted cells,the volume and weight of lung tumor in ABCB1 knockout cell-transplanted GPRC5A-/-C57BL/6 mice were significantly smaller than those in wild type cell-transplanted mice(P=0.0043,P=0.0060).Furthermore,immunofluorescence and immunoprecipitation assays showed that GPRC5A regulated ABCB1 expression by direct binding. Conclusion GPRC5A reduces lung adenocarcinoma proliferation via inhibiting ABCB1 expression.The pathway by which GPRC5A regulates ABCB1 expression needs to be investigated.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

AIM: To evaluate the clinical efficacy of wearing base curve aspheric orthokeratology(OK)lens in the control of myopia.METHODS: A prospective study was conducted. A total of 94 cases(94 eyes)of myopia aged 8～13 years old who were fitted with orthokeratology(OK)lens in our hospital from January 2020 to July 2021 were selected(for patients who received OK lens in one eye, the eye is selected as the observation eye, and for patients who receive OK lens in both eyes, the right eye is used as the observation eye). Patients were divided into two groups according to the design of the OK lens, with 46 cases wearing base curve aspheric OK lens in study group and 48 cases wearing base curve spheric OK lens in control group. The study group and the control group were further divided into low myopia group(-3.00D< SE ≤-0.75D)and moderate myopia group(-6.00D< SE ≤-3.00D)according to the baseline spherical equivalent(SE), with 52 cases(52 eyes)in the low myopia group and 42 cases(42 eyes)in the moderate myopia group. Uncorrected visual acuity(UCVA)was evaluated at 1d, 1wk, 1, 3, 6 and 9mo after wearing lenses, and axial length were measured at 6mo and 1a after wearing lenses respectively.RESULTS: All patients completed follow-up, and there was no significant differences in UCVA(LogMAR)between the study group(-0.12±0.08)and the control group(-0.17±0.07)after wearing the OK lens for 1mo(P>0.05); the mean axial length elongation between the two groups had no significant differences after wearing lenses for 6mo and 1a(all P>0.05). In the low myopia group, the axial length elongation of the study group was 0.19±0.17mm after wearing OK lens for 1a, which was significantly lower than that of the control group(0.31±0.18mm; P<0.05); while in the moderate myopia group, the axial length elongation was 0.22±0.18mm, and it had no significant differences with that in the control group(0.19±0.12mm; P>0.05). There was no significant differences in axial length elongation between the low myopia group and the moderate myopia group in study group after wearing lenses for 6mo and 1a(P>0.05), while there was differences in axial length elongation between low myopia group and moderate myopia group in the control group after wearing lenses for 6mo(0.15±0.13 vs. 0.05±0.12mm)and 1a(0.31±0.18 vs. 0.19±0.12mm; all P<0.05).CONCLUSION: Wearing base curve aspheric OK lens can effectively improve the UCVA and control the elongation of axial length. For patients with low myopia, base curve aspheric OK lens had a better efficacy in controlling the elongation of axial length than the spheric OK lens.

ABSTRACT: Meningiomas are the most common primary intracranial neoplasm with diverse pathological types and complicated clinical manifestations. The fifth edition of the WHO Classification of Tumors of the Central Nervous System (WHO CNS5), published in 2021, introduces major changes that advance the role of molecular diagnostics in meningiomas. To follow the revision of WHO CNS5, this expert consensus statement was formed jointly by the Group of Neuro-Oncology, Society of Neurosurgery, Chinese Medical Association together with neuropathologists and evidence-based experts. The consensus provides reference points to integrate key biomarkers into stratification and clinical decision making for meningioma patients.

Objective To evaluate endoscopic ultrasonography (EUS) in diagnosis of gastric submucosal tumors (SMTs), and analyze the characteristics of gastric SMTs under EUS. Methods Clinical data of 614 patients with gastric SMTs, who were evaluated by EUS and underwent endoscopic submucosal dissection (ESD) from September 2008 to December 2016, were retrospectively analyzed. The golden standard for lession origins was the intraoperative diagnosis of ESD, and that for pathological types was the combination of postoperative pathological and immunohistochemical findings. The consistency of diagnosis of EUS was evaluated, and the characteristics of lesions under EUS were analyzed. Results The total consistency in diagnosing lesion origins was 91.25％ between EUS and intraoperative results of ESD, and the consistency in diagnosing lesion originated from the muscularis mucosa, submucosa and muscularis propria was 66.67％, 80.85％ and 94.50％, respectively. The total consistency in pathological types was 65.99％ between EUS and postoperative pathological results, and the consistency of gastrointestinal stromal tumor (GIST), leiomyoma, ectopic pancreas and lipoma was 91.85％, 18.56％, 79.76％ and 90.70％, respectively. Conclusion EUS can initially determine the origins and types of gastric SMTs, providing a more accurate basis for endoscopic treatment, but there were some limitations on the diagnosis of leiomyoma and some rare lesions such as hamartoma, inflammatory fibrous polyps, carcinoid, fibroma, etc. Thus, if necessary, the lesion should be removed so as to make a definite diagnosis and prevent malignant change.

Diabetic retinopathy (DR), one of the most serious complications of diabetes, has been associated with inflammatory processes. We have recently reported that interleukin (IL)-17A, a proinflammatory cytokine, is increased in the plasma of diabetic patients. Further investigation is required to clarify the role of IL-17A in DR. Ins2(Akita) (Akita) diabetic mice and high-glucose (HG)-treated primary Müller cells were used to mimic DR-like pathology. Diabetes induced retinal expression of IL-17A and IL-17 receptor A (IL-17RA) in Müller cells in contrast to ganglion cells. Further evidence demonstrated that retinal Müller cells cultured in vitro increased IL-17A and IL-17RA expression as well as IL-17A secretion in the HG condition. In both the HG-treated Müller cells and Akita mouse retina, the Act1/TRAF6/IKK/NF-κB signaling pathway was activated. IL-17A further enhanced inflammatory signaling activation, whereas Act1 knockdown or IKK inhibition blocked the downstream signaling activation by IL-17A. HG- and diabetes-induced Müller cell activation and dysfunction, as determined by increased glial fibrillary acidic protein, vascular endothelial growth factor and glutamate levels and decreased glutamine synthetase and excitatory amino acid transporter-1 expression, were exacerbated by IL-17A; however, they were alleviated by Act1 knockdown or IKK inhibition. In addition, IL-17A intravitreal injection aggravated diabetes-induced retinal vascular leukostasis, vascular leakage and ganglion cell apoptosis, whereas Act1 silencing or anti-IL-17A monoclonal antibody ameliorated the retinal vascular damage and neuronal cell apoptosis. These findings establish that IL-17A exacerbates DR-like pathology by the promotion of Müller cell functional impairment via Act1 signaling.

BACKGROUND:Integrated Traditional Chinese and Western Medicine minimaly invasive treatment for halux valgus based on wrapped curtain method with “8”-shaped bandage and sub toe pad external fixation has been used for a long time in the clinic. This method abandons the internal implant fixationandexternal plaster fixation. After surgery, patients could take care of themselves. However, theactivity of the broken end may cause fracture nonunion, which once aroused scholars’ question. Recently, with the continuous improvement of foot biomechanics research, foot finite element model and applications become a reality.
OBJECTIVE:To evaluate thestability of osteotomy after the operation of wrapped curtain method with“8”-shaped bandage and sub toe pad external fixation on the basis of static finite element method.
METHODS:A young female volunteer with halux valgus was selected, whose body weight was 58 kg, and right foot halux abductor valgus angle was 24°; intermetatarsal angle was 13°; proximal articulator set angle was 7°; distal articulator set angle was 7°. CT was used to scan the right foot. ABAQUS software was applied to establish a finite element model of right foot halux valgus bone, and model of the first metatarsal neck minimaly invasive osteotomy was simulated based on wrapped curtain method with external fixation. Von Mises stress and displacement at the osteotomy endwere calculated.
RESULTS AND CONCLUSION:(1) The maximum stress was 0.067 MPa without external fixation, and the maximum stress was 1.258 MPa with the external fixation. Stress was mainly distributed in the outer edge of the osteotomy. (2) The maximum absolute displacement was 0.363 mm without external fixation, and the maximum absolute displacement was 0.716 mm with external fixation. The two largest displacements were both in the Z-axis direction. Statistical analysis confirmed that the four nodes absolute displacement and stress were significantly different (P< 0.01). (3) The maximum relative displacement was 0.101 mm. The maximum relative displacement was 0.046 mm with external fixation. The maximum relative displacement without external fixation was-0.102 mm and occurred in the Z-axis. The maximum relative displacement with external fixation was 0.110 mm and occurred in the Y-axis. (4) One-way analysis of variance confirmed that the four nodes relative displacements were not statisticaly significant in X-axisand Y-axis (P> 0.05). The four nodes relative displacements were statisticaly significant in Z-axis (P< 0.05). (5) These findings suggest that the external fixation based on wrapped curtain method after halux valgus surgery could effectively reduce osteotomy displacement. The moderate stress and elastic fixation are conducive to fracture healing.

Objective To explore the applicability of 2 different models of occupational health risk assessment in wooden furniture manufacturing industry.Methods American EPA inhalation risk model and ICMM model of occupational health risk assessment were conducted to assess occupational health risk in a small wooden furniture enterprises,respectively.Results There was poor protective measure and equipment of occupational disease in the plant.The concentration of wood dust in the air of two workshops was over occupational exposure limit (OEL),and the CTWA was 8.9 mg/m3 and 3.6 mg/m3,respectively.According to EPA model,the workers who exposed to benzene in this plant had high risk (9.7×10-6～34.3×10-6) of leukemia,and who exposed to formaldehyde had high risk (11.4×10-6) of squamous cell carcinoma.There were inconsistent evaluation results using the ICMM tools of standard-based matrix and calculated risk rating.There were very high risks to be attacked by rhinocarcinoma of the workers who exposed to wood dust for the tool of calculated risk rating,while high risk for the tool of standard-based matrix.For the workers who exposed to noise,risk of noiseinduced deafness was unacceptable and medium risk using two tools,respectively.Conclusion Both EPA model and ICMM model can appropriately predict and assessthe occupational health risk in wooden furniture manufactory,ICMM due to the relatively simple operation,easy evaluation parameters,assessment of occupational-disease-inductive factors comprehensively,and more suitable for wooden furniture production enterprise.
