OBJECTIVE:To explore the ideas for the prescription comment of TCM injections,and provide reference for clini-cal rational use. METHODS:Totally 9 457 prescriptions in PIVAS and 400 hospitalized medical records in our hospital in 2015 were collected. The prescriptions and hospitalized medical records which contained TCM injections were retrospectively commented in aspects of indications,usage and dosage,drug combination,solvent selection and repeat medication,and analysis of typical case. RESULTS:In 2015,there were 2 544 prescriptions(26.90%)in PIVAS and 195 medical records(48.75%)that used TCM injections;the irrational use was mainly inappropriate solvent selection(50.70%),inappropriate usage and dosage(27.00%),inap-propriate indications (10.33%),inappropriate combination therapy (7.51%) and repeat medication (4.46%). CONCLUSIONS:Prescription of TCM injections should be commented with the medical records and individual analyzed;in terms of unreasonable prescriptions and medical records TCM clinical pharmacists should actively intervene unreasonable prescriptions by the bed.

Objective To assess the incidence and prognosis of the bronchial anastomosis complications following lung transplantation.Methods Between January 2003 and July 2016,all 81 cases after lung transplantation at Department of Thoracic Surgery of Shanghai Pulmonary Hospital,Tongji University were retrospectively analyzed.We analyzed the incidence and prognosis of postoperative complications of bronchial anastomosis in lung transplant recipients.Results The overall incidence of bronchial anastomotic complications was 30.9％,including anastomotic infection (18.5 ％),anastomotic fistula (4.9 ％),stenosis (6.2 ％),and bronchomalacia (1.2 ％).One case died of infection,and 3 cases died of anastomotic fistula.Conclusion The main bronchial anastomosis complications occurred early,and the prognosis was acceptable.

The incidence of lung cancer in China ranks first and second among men and women respectively .Meanwhile, lung cancer is also the leading cause of death in malignant tumors in China .Surgical treatment is of great significance in impro-ving the prognosis of patients with lung cancer, and the number of related clinical trials is increasing year by year.Through a retrospective review of clinical trials in the field of lung cancer and thoracic surgery on the Clinicaltrials .gov platform, this arti-cle finds that relevant clinical trials focus on treatment , perioperative management and basic research.Although the clinical tri-als in China started late, they have developed rapidly and the number of clinical trials ranked second.In addition, there are some shortcomings in the clinical trials of China in terms of trial design and research scope , and there is still a gap between Chinese and foreign trials.

Objective This study aims to analyze the clinical epidemiology,diagnostic and treatment characteristics of minor patients with maxillofacial fracture and provide a reference for the prevention and treatment.Methods The clinical data of minor patients with maxillofacial fracture in Department of Traumatic and Plastic Surgery,West China Hospital of Stomatology,Sichuan University,from January 1,2015 to December 31,2020 were retrospectively studied and statistically analyzed in terms of age,gender,etiology,anatomic sites and treatment modalities.Results The mean age of the patients was(10.65±5.15)years,and the male-to-female ratio was 1.91∶1.High fall was the primary cause of maxillofacial fractures in minors aged 0-6 years.Traffic accident injuries were the main cause of maxillofacial fractures in minors aged 7-12 and 13-17 years.About 65.13%of the midface and 83.08%non-condylar fractures were mainly treated by surgery,and condylar fractures were treated conservatively in 74.73%and by surgical treatment in 25.27%.Conclusion The etiology of maxillofacial fractures in minors differs at different ages,so prevention strategies should be adjusted according to age.Surgical treatment has become the preferred treatment modality for midface and non-condylar fractures.Conservative treatment is still the main treatment method for condylar fractures,but the proportion of surgical treatment increases.

Currently, cell transplantation in combination with scaffold materials are one of the main strategies in periodontal bone tissue engineering. In periodontal bone tissues, the stiffness and spatial structure of tissues such as alveolar bone and cementum differ, and the difference in mechanical properties of scaffolds also has disparate effects on the proliferation and differentiation of stem cells. Accumulating evidence shows that mechanical stimulating factors such as matrix stiffness and scaffold topography modulate biological behaviors of various seeding cells, including adipose-derived stem cells and periodontal ligament stem cells. A hard matrix can promote cytoskeletal stretching of stem cells, leading to nuclear translocation of Yes-associated protein (YAP) and promoting osteogenic differentiation by upregulating alkaline phosphatase (ALP) and osteocalcin (OCN) via the Wnt/β-catenin pathway. The topologic structure of scaffolds can affect cell adhesion and cytoskeletal remodeling, increase the hardness of cells and promote the osteogenic differentiation of stem cells. In this paper, the effects of mechanical stimulation on the differentiation of stem cells in periodontal bone tissue engineering are reviewed.

Voluntary contribution has become the only source of donor lungs in China since 2015. To elaborate the outcomes of patients awaiting lung transplantation (LTx) after the implementation of donation after brain death, we performed a retrospective study that encompassed 205 patients with end-stage lung disease who registered for LTx at Shanghai Pulmonary Hospital from January 1, 2015 to January 1, 2021. A total of 180 patients were enrolled in the study. The median waiting time was 1.25 months. Interstitial lung disease (ILD) (103/180, 57.2%) and chronic obstructive pulmonary disease (COPD) (56/180, 31.1%) were the most common diseases in our study population. The mean pulmonary artery pressure (mPAP) of patients in the died-waiting group was higher than that of the survivors (53.29±21.71 mmHg vs. 42.11±18.58 mmHg, P=0.002). The mortality of patients with ILD (34/103, 33.00%) was nearly twice that of patients with COPD (10/56, 17.86%) while awaiting LTx (P=0.041). In the died-waiting group, patients with ILD had a shorter median waiting time than patients with COPD after being listed (0.865 months vs. 4.720 months, P=0.030). ILD as primary disease and mPAP > 35 mmHg were two significant independent risk factors for waitlist mortality, with hazard ratios (HR) of 3.483 (95% CI 1.311-9.111; P=0.011) and 3.500 (95% CI 1.435-8.536; P=0.006). Hence, LTx is more urgently needed in patients with ILD and pulmonary hypertension.

ObjectiveBased on ultra-performance liquid chromatography-quadrupole-electrostatic field orbitrap high resolution mass spectrometry（UPLC-Q-Orbitrap-MS）， the chemical constituents of Qili Qiangxin capsules was identified， and their distribution in vivo was analyzed. MethodsUPLC-Q-Orbitrap-MS was used to detect the sample solution of Qili Qiangxin capsules， as well as the serum， brain， heart， lung， spleen， liver and kidney tissues of mice after oral administration. Using the Thermo Xcalibur 2.2 software， the compound information database was constructed， and the molecular formulas of compounds corresponding to the quasi-molecular ions were fitted. Based on the information of retention time， accurate relative molecular mass and fragments， the compounds and their distribution in vivo were analyzed by comparing with the data of reference substances and literature. ResultsA total of 233 compounds， including 70 terpenoids， 60 flavonoids， 23 organic acids， 17 alkaloids， 20 steroids， 7 coumarins and 36 others， were identified or predicted from Qili Qiangxin capsules， 73 of which were identified matching with standard substances. Tissue distribution results showed that 71， 17， 38， 33， 32， 58 and 43 migrating components were detected in blood， brain， heart， lung， spleen， liver and kidney， respectively. Thirty-seven components were absorbed into the blood and heart， including quinic acid， benzoylaconitine benzoylmesaconine and so on. Fourteen components were absorbed into the blood and six tissues， including calycosin， methylnissolin， formononetin， alisol B， alisol A and so on. ConclusionThis study comprehensively analyzes the chemical components of Qili Qiangxin capsules and their distribution in vivo. Among them， astragaloside Ⅳ， salvianolic acid B， ginsenoside Rb₁， ginsenoside Rb₃， ginsenoside Rd， ginsenoside Rg₃， calycosin-7-glucoside， and sinapine may be the important components for the treatment of heart failure， which can provide useful reference for its quality control and research on pharmacodynamic material basis.
