OBJECTIVETo study the effect of different composition structures of total paeony glycoside (TPG) component and total phenolic acid of Ligusticum chuanxiong ( TLPA) on sodium dithionite (Na2S2O4) -induced human umbilical vein endothelial cells (HUVEC) hypoxic injury. The baseline geometric proportion was used to design different components structure. And then the best structure of components by cell injury model were optimized.
METHODA HUVEC hypoxic injury model was established by being induced of Na2S2O4. Cell viability was measured by MTI colorimetric method, intracellular superoxide dismutase (SOD) activity, malondialdehyde (MDA), lactate dehydrogenase( LDH) levels, nitric oxide (NO) contents were measured by kits. At last, Western blot analysis was used to detect the expression of two proteins, Bcl-2 and Bax.
RESULTCompared with the model group, TPG component, TLPA component at different composition structures can significantly increase SOD activity and decrease MDA, LDH, NO levels (P < 0.01, P < 0.05). Paeoniae Radix Rubra and Chuanxiong Rhizoma components can downregulate the expression of Bax protein and upregulate the expression of Bcl-2 protein. The ratio of Bcl-2 and Bax was significantly increased (P < 0 01, P < 0 05), it means that cell apoptosis was inhibited. The results indicate that among all the component composition structures, TPG and TLPA component at the proportion of 8: 2 had the best protection on hypoxic injury of endothelial cells.
CONCLUSIONTPG component and TLPA component can resist HUVEC hypoxia injury, the protective effect was the most evident under the structure of 8: 2, which may be due to the inhibition of intracellular lipid peroxidation and cell apoptosis.

OBJECTIVETo analyze the neglected hidden blood loss before and after operations in the elderly patients with intertrochanteric fractures and strengthen the treatment and clinical nursing in the perioperative period in order to ensure clinical effects.
METHODSThe clinical data of 99 patients with intertrochanteric fracture treated with intramedullary nailing from January 2010 to January 2014 were retrospectively analyzed (47 males and 52 females). Forty-seven cases got blood transfusion supporting and 52 cases were not (blood transfusion group and no-blood transfusion group respectively). According to the Gross equation, the average hemoglobin (Hb) and hematocrit (HCT) were used to analyze blood loss in perioperative period and assess the patients' hidden blood loss situation.
RESULTSThere were 22 males and 30 females in blood transfusion group. The average operative time was (62.13±4.01) min; intraoperative visible blood loss and postoperative drainage were 215 ml, totally; preoperative Hb was (103.22±9.01) g/L and postoperative was (81.13±6.20) g/L; preoperative HCT was (96.93±3.38) I/L and postoperative was (308.00±11.81) I/L. There were 25 males and 22 females in no-blood transfusion group. The average operative time was (60.12±3.27) min; intraoperative visible blood loss and postoperative drainage were 196 ml, totally; the average blood transfusion were 621 ml; preoperative Hb was (92.15±5.46) g/L and preoperative was (95.20±8.93) g/L; preoperative HCT was (96.52±3.63) I/L and preoperative was (392.70±14.03) I/L. According to the Gross equation, the blood loss of no-blood transfusion group and blood transfusion group in peroperative period were (937.29±63.04) ml and (706.43±35.02) ml, respectively. The hidden blood loss was dominant. At 1, 3 months after operation, Harris score of blood transfusion group was better than that of no-blood transfusion group, and 12 months after operation, there was no significant difference between two groups.
CONCLUSIONThe hidden blood loss of intramedullary nailing for intertrochanteric fracture should be emphasized in perioperative period, it can avoid the perioperative complications caused by anemia and affect the prognosis of patients.

OBJECTIVETo evaluate the technique and therapeutic effect of sternoclavicular hook plate fixation in treating sternoclavicular joint (SCJ) dislocation.
METHODSFrom January 2010 to March 2014,6 patients with SCJ dislocation were treated with sternoclavicular hook plate fixation in our hospital. Among the 6 patients, 5 patients were male and 1 patient was female, and the average age was 34 years, ranging from 26 to 48 years. The course of the disease ranged from 3 to 20 days. All the SCJ dislocations were caused by external injury and accompanied with the symptoms of swelling pain and obvious shoulder joint activity restricted in affected side. All SCJ dislocations were anterior dislocation by the diagnosis of X-ray and CT scan. The postoperative curative effect was evaluated according to Rockwood score.
RESULTSAll the patients' operative incision were healed well and in good appearance. X-ray showed that the dislocated SCJ was well reduced and the plate was on right position. All the 6 patients were followed up for 4 to 18 months, with an average of 12 months. The results were evaluated according to Rockwood score, 4 got excellent results, 1 good and 1 fair. No fixation loosening, redislocation or side injury such as vessel, nerve or pleura injury were found.
CONCLUSIONWith sternoclavicular hook plate fixation, SCJ dislocation could be reduced while keeping its amphiarthrodial function and the completeness of the cartilage surface. Sternoclavicular hook plate fixation has advantages of safety and stabilization in fixation, and patients can begin function exercises earlier.

Academic Journal of Second Military Medical University 2019;40(4):377-380
Objective To analyze the correlation between adjacent segment disease (ASDis) after lumbar fusion and spinopelvic sagittal parameters, and to explore the risk factors. Methods From Jan. 2013 to Oct. 2017, the patients undergoing revision surgery for ASDis after lumbar fusion in Changhai Hospital of Naval Medical University (Second Military Medical University) were enrolled as ASDis group, and the patients who did not have ASDis after lumbar fusion during the same follow-up period were taken as controls. The clinical data of the patients in the two groups were retrospectively analyzed. The differences of the general data (age, gender, body mass index [BMI], follow-up time and the etiology of the first operation) and the spinopelvic sagittal parameters (thoracic kyphosis [TK], sagittal vertical axis [SVA], lumbar lordosis [LL], segmental lumbar lordosis [sLL], pelvic incidence [PI], pelvic tilt [PT] and sacral slope [SS]) were compared between the two groups. Results There were 25 patients in the ASDis group and 50 patients in the control group. There were no significant differences in the age, gender, BMI, follow-up time or the etiology of the first operation between the two groups (all P>0.05). Compared with the control group, the LL, sLL and SS were significantly lower in the ASDis group (36.00°±5.44°vs 43.88°±10.62°, 17.80°±5.79°vs 27.62°±6.74°, 27.50°±5.30°vs 31.06°±7.48° all P<0.05), while the PT was significantly greater (26.12°±8.24°vs 18.80°±7.67°, P<0.01). There were no significant differences in the TK or PI between the two groups (both P>0.05). Meantime, the proportion of patients with SVA>50 mm, the difference of PT and LL (PT-LL)=10°, and the ratio of sLL to LL (RL)<60% were significantly higher in the ASDis group than those in the control group (18/25 vs 21/50, 16/25 vs 11/50, 21/25 vs 17/50; all P<0.05). Conclusion The sagittal imbalance after lumbar fusion is closely associated with ASDis, and compensatory kyphosis of adjacent lumbar segments due to surgical segmental lordosis may be one of the causes of ASDis after lumbar fusion.
8. Clinical application of bone morphogenetic protein 2: Adverse reaction
Academic Journal of Second Military Medical University 2019;40(9):1010-1014
Bone morphogenetic protein 2 (BMP2) is an active protein inducing bone formation, and it can regulate the proliferation of mesenchymal stem cells into osteoblasts. In 2002 BMP2 was approved by the US Food and Drug Administration for single-segment anterior lumbar intervertebral fusion surgery. However, during the clinical application, BMP2 was found to have the following adverse reactions: heterotopic ossification, osteolysis and graft sinking, formation of bone cysts, inflammation-related complications, radiculitis, retrograde ejaculation and carcinogenesis. These adverse reactions may be due to the off-label use of BMP2 and use of off-physiological dose. This review mainly sums up the adverse reactions in the clinical application of BMP2, hoping to provide reference for safer and more effective clinical medication.
9. Role of bone morphogenetic protein 2 in occurrence and development of ligamentum flavum ossification
Academic Journal of Second Military Medical University 2018;39(4):428-432
The ossification of ligamentum flavum (OLF) is a major cause of thoracic spinal stenosis. Due to insidious onset, OLF usually results in severe compression of spinal cord when discovered, and the clinical outcomes are poor. Therefore, novel and effective diagnostic and therapeutic approaches for OLF are greatly needed. Bone morphogenetic protein 2 (BMP-2), a member of the transforming growth factor β family, possesses a critical role in the differentiation of mesenchymal stem cells towards osteoblastic lineage and endochondral ossification in the early stage of embryonic development. Increasing researches revealed that OLF, especially the continuous multilevel ossification, correlates closely with BMP-2. In this review, we summarized the advances on the role of BMP-2 in the occurrence and development of OLF, and prospected the application of BMP-2 as a potential target in the diagnosis, therapy and prognosis monitoring of OLF.

OBJECTIVETo investigate the changes in the quantity of colonizing Streptococcus mutans(S. mutans) and Actinomyces on the root surface plaque before and after post-core crown restoration of the mandibular first molars in the elderly patients.
METHODSA total of 30 elderly patients, each with one post-core crown restoration of the mandibular first molar, were randomly chosen to participate in the studies. Patients with mandibular first molars with post-core crown restoration and those with healthy contralateral mandibular first molars were divided into the test and control groups, respectively. Root surface plaques of the two groups were collected before tooth preparation, 72 h after preparation, one week after preparation, and one month after restoration. S. mutans, Actinomyces naeslundii (A. naeslundii) and Actinomyces viscosus (A. viscosus), were identified using colony morphology, biochemical techniques, and polymerase chain reaction (PCR). Plaque count was measured using microbial colony count.
RESULTSThe number of S. mutans and A. viscosus and A. naeslundii in the test group, which was statistically significant (P<0.05), increased 72 h after preparation. The quantities of S. mutans, A. viscosus, and A. naeslundii one week after preparation were significantly different (P<0.05). The plaque count of S. mutans, A. viscosus, and A. naeslundii in the test group decreased one month after restoration (P<0.05).
CONCLUSIONThe quantities of S. mutans, A. viscosus and A. naeslundii increase one week after preparation but decrease one month after restoration. The finding suggests that dentists should educate patients about plaque control during the early period after tooth preparation.
