OBJECTIVETo provide a theoretical basis for designing of lumbar intervertebral disc prosthesis by collecting the data of the lumbar endplate morphology.
METHODSA total of 100 healthy adults were measured about the following parameters: lumbar lordosis, the Cobb angle of each segment, the concavity depth (ECD) of the endplate, the location of concavity apex (ECA) of the endplate. And a correlation analysis on lumbar lordosis and ECD, ECA was made, respectively.
RESULTSIn total, 100 volunteers were measured. The mean age of the volunteer was 40 years (range 20 - 50 years); the average depth of ECD was (2. 37 ± 1. 42) mm, the average location of ECA was (52. 21 ± 9. 70) %; the average depth of ECD of inferior endplate (IEP) was (2. 81 ± 1. 52) mm (0. 54 - 7. 60 mm), and the parameter of the superior endplate (SEP) was (1. 94 ± 1. 16)mm(0. 39 - 6. 10 mm). The average depth of ECD of the IEP was bigger than of the SEP for each lumbar vertebral body. Most of the location of ECA was at the back of the intervertebral body, the average location of ECA of IEP was (49. 60 ± 8. 78) % (22. 57% - 75. 58%), and the parameter of the SEP was (55. 03 ± 9. 90) % (16. 03% -75. 58%); the mean angle of lumbar lordosis was 39. 760 11. 25°(13. 8° - 72. 00°). There was no obvious correlation between the lumbar lordosis and the ECD (r -0. 193, P =0. 195), neither was the location of ECA(r =0. 080, P =0. 592).
CONCLUSIONMost of the location of ECA is at the back of the intervertebral body, the average depth of ECD is 2. 37 mm, the average location of ECA is 52. 21%.

Objective To investigate the effect of vitamin D (VD) on gastric cancer and its underlying mechanisms by detecting serum VD levels in gastric cancer patients and the expression of vitamin D receptor (VDR) in gastric tumor.Methods Serum VD levels was detected by enzyme linked immunosorbent assay,VRD expression of tumor tissue and normal mucosa were detected by immunohistochemistry.At the same time,relationships of VDR expression and the prognosis of the patients were analyzed.Results The serum levels of VD of gastric cancer patients were lower than that of healthy people (P<0.05),and they were negatively related to the degree of cell differentiation significantly (P<0.001).VDR expression in gastric tumor tissue significantly decreased compared to that of the normal mucosa (P<0.05).A significant correlation was found between the VDR expression and the differentiation grade of the carcinoma,with well differentiated carcinoma having the highest level of VDR expression (P<0.05).For patients with gastric cancer,those with positive VDR expression had significant longer progression-free survival (PFS) and overall survival (OS) than the patients with negative VDR expression (P<0.05).Conclusions VD may be a protecting factor of gastric cancer.VDR can be regarded as a marker of differentiation of gastric cancer and served as an effective prognostic factor in patients with postoperative gastric cancer.

Objective To investigate the effect of acupuncture combined with Shenfu injection on brain injury and hemodynamics after cardiopulmonary resuscitation in patients with cardiac arrest.Methods A total of 100 patients who underwent cardiopulmonary resuscitation after cardiac arrest admitted to 903rd Hospital of the Joint Support Force of PLA from May 2019 to May 2022 were selected as the research objects,and they were divided into acupuncture group and combined group,with 50 cases in each group according to the random number table method.The acupuncture group was given acupuncture therapy,and the combined group was injected Shenfu injection on the basis of acupuncture group.S100β,neuron specific enolase(NSE),National Institutes of Health stroke scale(NIHSS)score,mini mental status examination(MMSE)score,hemodynamic index,Glasgow coma scale(GCS)score,acute physiology and chronic health evaluation Ⅱ(APACHE Ⅱ)score and incidence of adverse reactions were compared between two groups.Results After treatment,S100β,NSE,NIHSS score,APACHE Ⅱscore,and heart rate(HR)of two groups were significantly lower than those before treatment,MMSE score,GCS score,cardiac output(CO),central venous pressure(CVP),mean arterial pressure(MAP)were significantly higher than those before treatment(P<0.05).S100β,NSE,NIHSS score,APACHE Ⅱ score and HR in combined group were significantly lower than those in acupuncture group,and MMSE score,GCS score,CO,CVP,and MAP were significantly higher than those in acupuncture group(P<0.05).The incidence of adverse reactions in combined group was significantly lower than that in acupuncture group(χ2=6.453,P=0.011).Conclusion Acupuncture combined with Shenfu injection treatment can improve brain injury and hemodynamics after cardiopulmonary resuscitation in patients with cardiac arrest,and the effect is significant.

Objective To apply real-time transperineal ultrasound ( TPUS) to monitor the intra-fractional prostate motion,collect and analyze the data of the prostate motion,aiming to provide evidence for the optimization of the target area and plan of radiotherapy for prostate cancer. Methods TPUS is a non-invasive monitoring technique that utilizes an automatic scanning ultrasound probe to dynamically monitor and correct the motion of organs during radiotherapy. In this study, TPUS was utilized to collect 1588 intra-fractional data of 70 patients with prostate cancer. Prior to each cycle of radiotherapy,CBCT was adopted to correct the errors between intra-factional data by using VMAT. During radiotherapy, real-time ( once per second) ultrasound images were acquired to monitor the 3D motion of the prostate on the x (left+,right-),y (cranial+, caudal-), and z ( abdominal+, dorsal-) axes, emphasizing the analysis of 4D motion of the prostate. Results All patients successfully completed the treatment and data collection. The median time of effective monitoring per faction was 179 seconds (132-286 seconds). During 95% of the monitoring time,the distance of prostate motion was 2. 22 mm in the left direction,2. 17 mm in the right,2. 08 mm in the cranial, 1. 98 mm in the caudal,2. 44 mm in the abdominal and 2. 97 mm in the dorsal direction,respectively. In the x,y and z axes,the percentage of time in which the distance of prostate motion less than 1 mm among the total time was 83. 07%,85. 46% and 78. 27%,respectively,whereas 97. 70%,97. 87% and 96. 45% for<3 mm, respectively. Conclusions TPUS is a non-invasive real-time monitoring technique,which can detect the 4D motion of the prostate during radiotherapy. By using VMAT,the range of prostate motion is relatively small, and the motion range is less than 3 mm in each direction within 95% of the time.

【Objective】 To explore the laboratory monitoring procedure and its clinical significance in patients with passenger lymphocyte syndrome after liver transplantation. 【Methods】 The Hb and bilirubin levels were monitored in one AB blood type patient post-liver transplantation. The ABO blood group type, unexpected antibody screening test, direct anti-globulin test and acid elution test were performed respectively in blood samples of the patient to identify the serum antibodies and erythrocyte membrane sensitized antibodies. 【Results】 The patent’s Hb level showed a decreasing trend on the day 11 post-operation, reaching the lowest level of 62 g/L on day 17, and his serum bilirubin increased. The patient’s ABO blood type was determined as AB while anti-B antibody was detected in the patient’s serum. The direct anti-globulin test was weakly positive, while the unexpected antibody screening test was negative. Anti-B antibody was detected in the elution and the patient’s serum. The patient′s serum was incompatible with type AB and type B erythrocytes in the cross-matching test, while it was compatible with type A and type O erythrocytes. 【Conclusion】 Through monitoring serum anti-A, anti-B and direct anti-human globulin test, the patients with passenger lymphocyte syndrome after liver transplantation can be early diagnosed and the prognosis can be improved.

【Objective】 To investigate and analyze the serological and molecular biological characteristics of B(A) subgroup in a tertiary hospital in Jiaozhou, Qingdao. 【Methods】 From November 2019 to February 2023, the samples of 12 patients were suspected to be AB subgroup by microcolumn glass bead method and saline test tube method. The exons 6 and 7 of ABO gene were further amplified, sequenced and analyzed to determine the ABO allele type. 【Results】 A total of 9 cases of B(A) subgroup were detected in 26 065 patients in Jiaozhou, with a detection rate of 0.345 ‰ ( 9/26 065 ). Among the 9 cases of B(A) subgroup, 8 cases of serological reaction showed A
