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.

Objective: To investigate the correlation between CLOCK and BMAL1 genes and MEN2 medullary thyroid carcinoma (MTC). Methods: Thirteen cases with MEN2 MTC and thirteen cases with non-MEN2 MTC were selected who were treated in the Yantai Yuhuangding Hospital between January 2013 and September 2021. Clinical indicators such as blood calcitonin level, tumor diameter and metastatic lymph node of patients were collected. The expression differences of CLOCK and BMAL1 between MEN2 MTC and para-carcinoma tissue as well as between MEN2 MTC and non-MEN2 MTC were detected by immunohistochemistry and qPCR. The correlation between lymph node metastasis and CLOCK or BMAL1 expression was analyzed. Protein-protein interaction (PPI) network analysis combined with qPCR and correlation analysis was used to explore the expression regulation relationship between RET and circadian clock genes. The rhythm disorder of MEN2 cells was verified by lipopolysaccharide cell stimulation experiment after dexamethasone rhythm synchronization. Results: MEN2 MTC exhibited typical RET gene mutation. The mean blood calcitonin level, the tumor diameter and the number of metastatic lymph nodes of patients with MEN2 MTC were higher than those of patients with non-MEN2 MTC (t value was 2.76, 2.53, 2.26, all P<0.05). Immunohistochemical results showed that the expression levels of CLOCK and BMAL1 in MEN2 MTC were higher than those in non-MEN2 MTC, while negatively expressed in para-cancerous thyroid follicle. qPCR displayed that the expression of CLOCK gene in cancer tissues was higher than that in non-MEN2 MTC and para-cancerous tissues (t value was 2.68 and 2.86, all P<0.05); the expression of BMAL1 gene in MEN2 MTC was higher than that in non-MEN2 MTC and para-cancerous tissues (t value was 2.21 and 2.35, all P<0.05). Correlation analysis showed that the expression levels of CLOCK and BMAL1 genes were positively correlated with the number of lymph node metastases in patients with MEN2 MTC (r=0.65, P<0.001; r=0.52, P=0.005). PPI network analysis indicated that the expression of CLOCK gene was positively correlated with the abnormal expression of RET gene (r=0.96, P<0.001). With lipopolysaccharide to stimulate cultured cells in vitro after dexamethasone rhythm synchronization, the expressions of CLOCK and BMAL1 in MEN2 MTC cells (0.47±0.22 and 2.60±1.48) at 12 hours of synchronization were significantly lower than those in para-cancerous tissues (1.70±1.62 and 8.23±2.52), the difference was statistically significant(t=5.04, P=0.007; t=3.34, P=0.029). Conclusion: CLOCK and BMAL1 are correlated with the occurrence and development of MEN2 MTC, and may be potential targets for the development of new therapeutic strategies for MEN2 MTC.

Objective To observe the clinical efficacy of Huajian-Badu membrane in the treatment of moderate and severe cancer pain. Methods The 80 malignant tumor patients with moderate to severe cancer pain from January 2016 to June 2017 in Tianjin University of Traditional Chinese Medicine First Teaching Hospital were recruited and randomly divided into the observation group and the control group, each of 40 cases. The control group were treated with Oxycodone Hydrochloride Prolonged-release Tablets, while the treatment group were treated with Huajian-Badu membrane on the basis of the treatment in control group. The pain relief, pain frequency, morphine consumption and quality of life (Karnofsky score), adverse reaction were evaluated between two groups before and after treatment. Results Compared with the control group, the total efficiency in the observation group was significantly higher (95.0％ vs. 80.0％, χ2=4.114, P=0.043). The frequency of breakthrough pain of two groups increased on the seventh and fourteenth treatment days(0.3 ± 0.6 times vs. 0.8 ± 0.7 times, t=-3.430 and 0.4 ± 0.6 times vs. 0.9 ± 0.8 times, t=-3.162), but the number of outbreaks of pain in the observation group significantly less than the control group (P<0.05 or P<0.01). The morphine injection dosage increased on the seventh and fourteenth treatment days (3.01 ± 4.28 g vs. 5.62 ± 6.37 g, t=-2.151 and 3.21 ± 4.32 g vs. 7.84 ± 7.76 g, t=-3.297), but the amount of the observtation group was significantly lower than that of control group (P<0.05 or P<0.01). The KPS score in the observation group increased significantly, and significantly higher than the control group on the seventh and fourteenth treatment days (73.0 ± 15.0 vs. 66.0 ± 12.0, t=2.305 and 77.0 ± 13.0 vs. 70.0 ± 15.0, t=2.230, P<0.05). The adverse reaction rate of the control group was 25％, while the the observation group was 20％. The difference between two groups was significant (χ2=0.287, P=0.592). Conclusions The Huajian-Badu membrane combined Oxycodone Hydrochloride Prolonged-release Tablets can improve the total effective rate of pain relief, reduce the number of outbreaks, reduce morphine consumption, improve patient KPS score of the patients with cancer pain.

Objective To observe the effect of Kidney-nourishing, Blood-activating, Phlegm-resolving and Resuscitation-inducing Decoction(KBPRD)on the expression of N-methyl-D-aspartate(NMDA)receptor subtype 1,2A,2B(NR1,NR2A,NR2B)in the cochlear spiral ganglion neurons(SGN)of tinnitus rats and to explore its mechanism, thus to provide experimental evidence for the treatment of tinnitus with KBPRD. Methods Sixty rats were randomly divided into normal group,model group,western medicine group,and low-,middle-,and high-dose Chinese medicine groups, 10 rats in each group. Rats were given intraperitoneal injection of sodium salicylate combined with water deprivation to induce tinnitus model. After successful establishment of the model, the rats in low-,middle-,and high-dose Chinese medicine groups were given gastric administration of KBPRD in the dosage of 5.5, 11, 22 g·kg-1·d-1 respectively, the rats in western medicine group were given gastric administration of 5 mg·kg-1·d-1 of carbamazepine,and rats in the model group and normal group were given gastric administration of 2 mL of normal saline,once every day,treatment time covering 8 weeks. The expression levels of NR1,NR2A,and NR2B in the cochlear SGN was detected by immunoblotting and real-time quantitative reverse transcription-polymerase chain reaction(qRT-PCR)after 8 weeks of treatment. Results Compared with the normal group,the expression levels of NR1, NR2A and NR2B in the model group were increased, the difference being significant (P < 0.05). Compared with the model group,the expression of NR1,NR2A and NR2B in low-,middle-,and high-dose Chinese medicine groups were significantly decreased(P<0.05).Conclusion KBPRD is effective on relieving tinnitus of rats, and its mechanism is correlated with lowering the increased expression of NR1,NR2A and NR2B in SGN of tinnitus rats.

BACKGROUNDThough trabeculectomy is often performed on patients with medically refractive pigmentary glaucoma (PG), the clinical outcomes of surgical treatment on PG remain unknown. The aim of this study was to summarize the long-term efficacy and safety of trabeculectomy on PG.

METHODSThis was a prospective case series observational study. Eighteen consecutive PG patients were followed up for 8 years after trabeculectomy from May 2006 to April 2007. Visual acuity (VA), best-corrected visual acuity (BCVA), slit lamp biomicroscopy, intraocular pressure (IOP) measurement, Humphrey visual field analysis (VFA), and stereoscopic funduscopy were performed on admission and every 6 months after the surgery. Postoperative IOP, VA, BCVA, VFA, adjunctive anti-glaucoma medication, treatment-related side-effects, changes in blebs, and main clinical findings in the anterior segment of PG were recorded and compared with the baseline.

RESULTSEighteen PG eyes from 18 patients, with average preoperative IOP of 34.5 ± 4.7 mmHg (range: 21-47 mmHg, 1 mmHg=0.133 kPa) were enrolled in this study. All enrolled patients completed the follow-up visits and required examinations. Eight years after trabeculectomy, all surgical eyes (18/18) had satisfactory IOP control with an average of 13.7 ± 2.5 mmHg (range: 9-19 mmHg), which was significantly lower than baseline (P = 0.001). Majority (15/18) of the PG eyes had stable VA, BCVA, VFA, and optic disc cupping parameters. Functional blebs still existed in 12/18 of the PG eyes at the last follow-up visit. Unanimously, pigmentation in the anterior segment attenuated with time after surgical treatment. No severe side-effects were recorded in any of the surgical eyes.

CONCLUSIONSAll surgical PG eyes in this study had satisfactory IOP control 8 years after the surgery with well-preserved visual function. The long-term efficacy and safety of trabeculectomy are promising in PG patients.

OBJECTIVETo explore the molecular mechanism of erythrocyte pyruvate kinase deficiency (PKD).

METHODSTargeted sequence capture and next-generation sequencing (NGS) were used to detect the regions of exon and exon-intron boundarie of PKLR gene in a clinical suspected PKD patient. The protein function of mutant gene was forecasted by the SIFT and PolyPhen-2 databank, after the mutation of PKLR gene in the patient was detected by the NGS technology, its genotype was confirmed by Sanger sequencing.

RESULTSThe patient was found to have peculiar double heterozygous mutations: 661 G>A (Asp221Asn) of exon 5 and 1528 C>T (Arg510Ter) of exon 10, resulting in amino acid substitution Asp221Asn and Arg510Ter, these mutations were also further confirmed by Sanger sequencing. The complex mutations were infrequent and each of them was able to cause diseases.

CONCLUSIONThe complex mutations of both 661 G>A and 1528 C>T of PKLR gene are the molecular mechanism of PKD. Simultaneous existance of above-mentioned complex mutations in PDK patient was never been previously reported at home and abroad.

BACKGROUNDA multi-center large scale study is needed to confirm the efficacy and safety of domestic peritoneal dialysis (PD) solutions. Some researchers believe that 6 L/d is enough for adequate dialysis, but there is no multi-center prospective study on Chinese population to confirm this. In this study, we evaluated the efficacy and safety of domestic PD solution (Changfu) and its difference between 6 L and 8 L dosage.

METHODSAdult PD patients who had taken PD therapy for at least one month were selected and divided into four groups according to two dialysis solution brands and two dialysis dosages, i.e., 6 L dose with Changfu dialysis solution, 6 L dose with Baxter dialysis solution, 8 L dose with Changfu dialysis solution, and 8 L dose with Baxter dialysis solution. After 48 weeks, the changes of primary and secondary efficacy indices were compared between different types and different dosages. We also analyzed the changes of safety indices.

RESULTSChanges of Kt/V from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of creatinine clearance rate (Ccr). Normalized protein catabolic rate (nPCR) from baseline to 48 weeks between Changfu and Baxter showed no statistical differences; so did those of net ultrafiltration volume (nUF) and estimated glomerular filtration rate (eGFR). Changes of nPCR from baseline to 48 weeks between 6 L and 8 L showed no statistical differences; so did those of nUF and eGFR. The decline of Kt/V from baseline to 48 weeks in 6 L group was more than that in 8 L group. Change of Ccr was similar. During the 48-week period, the mean Kt/V was above 1.7/w, and mean Ccr was above 50 L×1.73 m(-2)×w(-1). More adverse events were found in Changfu group before Changfu Corporation commenced technology optimization, and the statistical differences disappeared after that.

CONCLUSIONSThe domestic PD solution (Changfu) was proven to be as effective as Baxter dialysis solution. During 48-week period, a dosage of 6 L/d was enough for these patients to reach adequate PD. Clinical study promotes technological optimization, further helps to improve the safety indices of the medical products.

OBJECTIVETo explore the relationship between Chinese medicine (CM) constitutive susceptibility and syndrome diversity in diabetic nephropathy (DN).

METHODSEpidemiologic investigation on constitution adopting the "Constitution in Chinese Medicine Questionnaire" (CCMQ), and survey on syndrome type by CM syndrome scale (preliminary) were carried out in 180 DN patients. Cluster analysis on symptom items was used to determine the syndrome type, and canonical correlation analysis was used to analyze the relationship between patients' constitution and syndrome.

RESULTSBaseline levels in all enrolled patients were not different statistically. Cluster analysis showed 8 syndromes existed in DN patients, namely: I, qi-yin deficiency with qi-stagnancy type; II, yin-yang deficiency with heat-water-blood stasis type; III, qi-yin deficiency with dampness-heat type; IV, yin-yang deficiency with blood-stasis and heat type; V, qi-yin deficiency with stagnant heat type; VI, yin-yang deficiency with inner dampness-heat stagnancy type; VII, yin deficiency with heat stagnancy type; and VIII, Kidney (Shen)-Spleen (Pi) deficiency with stagnant heat type. Correlation analysis on the 8 syndromes and the 9 constitutions showed statistical significant correlations between syndrome III and dampness-heat constitution (P=0.0001); syndrome IV and blood-stasis constitution (P=0.0001); and syndrome VII and yin-deficiency constitution (P=0.0180).

CONCLUSIONCertain relationship revealed between CM constitutions and syndrome types; constitution decides the disease genesis, its syndrome type and prognosis, as well as the change of syndromes.

OBJECTIVETo explore the association of Chinese medicine constitution susceptibility to diabetic nephropathy (DN) and transforming growth factor (TGF)-β1 (T869C) gene polymorphism.

METHODSTGF-β1 gene polymorphism detected with polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was screened for 180 DN cases and 180 type 2 diabetic mellitus (T2DM) cases without combined DN. Patients with DN were surveyed epidemiologically with constitution in the Chinese medicine questionnaire (CCMQ). Binary logistic regression analysis was utilized to study the correlation between nine types of Chinese medicine constitution and TGF-β1 (T869C) gene polymorphisms.

RESULTSThe DN group has a higher frequency of TGF-β1 (T869C) gene polymorphism than the T2DM group, and CC/CT genotypes than the T2DM group [CC, CT, TT (DN group): 88, 87, 5 (cases) versus (T2DM group) 71, 73, 36 (cases), P<0.05]. The phlegm-dampness constitution, damp-heat constitution, and blood stasis constitution have correlations with TGF-β1 (T869C) gene polymorphism.

CONCLUSIONChinese medicine constitutions were associated with TGF-β1 (T869C) gene polymorphism, a potential predictor of susceptibility to DN in T2DM patients.
