[Objective] To investigate the theory of"Treat Pre-disease"about intermenstrual bleeding from TCM constitution. [Methods] Intermenstrual bleeding is a disease of the gynecology, and it is more likely to relapse. Constitution theory of TCM holds that people's physique has the character of separable, adjustable and physique relating to disease. [Results] The interphase bleeding in patients with often clinical performance for yin deficiency constitution,qi deficiency constitution, damp heat constitution, blood-stasis constitution. [Conclusion] We can use the "Treat Pre-disease" thought to correct the physical deviation of the patients with intermenstrual bleeding, preventing the disease and preventing its recurrence after cure.

Objective To study the effects of Panax Notoginseng Saponins (PNS) on the damaged expression of ZO-1 of brain microvascular endothelial cells caused by Aβ42.MethodsBrain microvascular endothelial cells were divided into normal control group, model group, PNS low-, medium- and high concentration groups. They were incubated for 24h in 5% CO2 incubator at 37℃ . Then cell vitality was detected by MTT colorimetric method and ZO-1 protein expression was tested by Western blot.Results Stimulation of Aβ42 reduced the activity of microvascular endothelial cells (P<0.01) and suppressed the expression of ZO-1 protein (P<0.01). Compared with the model group, the activity of microvascular endothelial cells of PNS groups, especially the high and medium dose groups (P<0.05), and increased the ZO-1 protein expression. Conclusion PNS can partly recover the barrier function of blood brain barrier through inhibiting the decrease of the activity of microvascular endothelial cells caused by Aβ42.

Objective:Human leukocyte antigen(HLA)B27 is a susceptibility allele of ankylosing spondylitis(AS),and HLA-B27 antigen typing is an important indicator for clinical diagnosis of AS,but current typing methods such as sequence specific primer polymerase chain reaction(PCR-SSP)still possess limitation.Therefore,this study aims to analyze the correlation between B27 subtypes and susceptibility to AS in Hunan Province by applying high-resolution polymerase chain reaction-sequence-based typing(PCR-SBT). Methods:Peripheral blood of 116 patients with suspected AS(suspected AS group)and 121 healthy volunteers(control group)admitted to the Second Xiangya Hospital from January 2020 to December 2020 were collected for HLA-B genotyping by PCR-SBT.Among the patients in the suspected AS group,23 patients were finally diagnosed with AS(confirmed AS group),and the remaining 93 undiagnosed patients served as the non-confirmed AS group.PCR-SBT and PCR-SSP were used to detect HLA-B27 typing in 116 patients with suspected AS,and the results of the 2 methods were compared. Results:The HLA-B27 allele frequency in the suspected AS group was significantly higher than that in the control group[11.63%vs 2.48%;P<0.001,odds ratio(OR)=5.18,95%confidence interval(CI)2.097 to 12.795].B*27:04,B*27:05,B*27:06,and B*27:07 were detected in the suspected AS group and the control group.The frequency of the B*27:04 allele in the suspected AS group was significantly higher than that in the control group(9.48%vs 1.24%;P<0.001,OR=8.346,95%CI 2.463 to 28.282).The positive rate of B27 in the suspected AS group and the confirmed AS group(B27+/+ and B27+/-)was significantly higher than that in the control group(χ2=16.579,P<0.001;χ2=94.582,P<0.001,respectively).Among the confirmed AS group,21 were HLA-B27 carriers,and the B27 positive rate in the confirmed AS group was 91.3%.PCR-SBT could achieve high resolution typing of the HLA-B gene locus,with higher sensitivity,specificity,positive predictive value,negative predictive value,and accuracy than PCR-SSP. Conclusion:PCR-SBT typing analysis shows a strong correlation between HLA-B * 27:04 and AS in Hunan province.The PCR-SBT method can be used as the preferred option for the auxiliary diagnosis of clinical AS.

Objective:To investigate the advantages and disadvantages and clinical effects of integrated acetabular quadrilateral surface buttress plate in the treatment of acetabular both column fractures.Methods:From September 2017 to March 2019, 14 patients with acetabular both column fractures were treated with integrated quadrilateral acetabular buttress plate and were followed up. The clinical data were retrospectively analyzed. There were 10 males and 4 females with an average age of 53.2 years (range, 26-75 years). Fracture classification were both column fractures according to the Letournel-Judet classification system, including 11 cases of combined posterior wall without posterior dislocation. The time from injury to operation was 8-19 days, with an average of 10.3 days. All operations were performed with a supra-ilioinguinal approach. After satisfactory reduction, the integrated acetabular quadrilateral surface buttress plate was used to fix the anterior and posterior column and quadrilateral fractures at the same time. After operation, Matta criteria was used to evaluate the quality of fracture reduction on postoperative images, and modified Merle d'Aubigné-Postel score to evaluate hip joint function.Results:The average operation time was 180 min (range, 120-320 min), and the intraoperative average blood loss was 980 ml (range, 700-1 600 ml). Operations were performed successfully with none intraoperative reshaping conducted, and the plate could fit into the bone surface well. All 14 patients were followed up with an average of 15.6 months (range, 9-20 months). During the follow-up, all fractures healed with an average of 3 months (range, 2.5-5 months). The reduction quality evaluated by the Matta criteria were 7 anatomical, 5 satisfactory, and 2 unsatisfactory, with an excellent and good rate of 85.7% (12/14). The hip joint function at the last follow-up was in accordance with the modified Merle d'Aubigné-Postel score was 12-18 points, with an average of 16.9 points, of which 8 excellent, 4 good, and 2 fair. The excellent and good function rate was 85.7% (12/14). During the operation, 1 patient had a rupture of about 1 cm of the peritoneum during the separation of the spermatic cord, which was immediately sutured and repaired. One patient had obturator nerve paralysis after the operation, without special treatment, and the paralysis symptoms were relieved during the 6th-month follow-up. There were no other operation-related complications.Conclusion:For both-column fractures characterized by central dislocation of the femoral head, the integrated acetabular quadrilateral buttress plate can simultaneously fix the anterior and posterior columns and quadrilateral surface at the same time. Satisfactory reduction and functional outcomes could be achieved by the novel plates.

Methylmalonic acidemia (MMA) is a rare autosomal recessive disorder, with the manifestation of recurrent and severe episodes of acute metabolic decompensation or a variety of long-term complications that require timely treatment.As liver transplantation (LT) developing widely, it has become an effective treatment for patients with severe MCM deficiency.Although LT does not solve the fundamental problem of gene defect, it can prolong survival, improve the quality of life of patients and reduce recurrent hospitalization rate, as well as lower urine, plasma MMA and propionyl carnitine levels and prevent metabolic stroke.After LT, the metabolism-correcting medications are still partially needed.Neurological symptoms of some patients can be alleviated but renal damage may remain irreversible.The domestic liver transplantation in the treatment of methylmalonic acidemia is being carried out, but there is still a lack of research on the effect of LT on MMA.The paper is to make a review of the clinical value of liver transplantation in the treatment of methylmalonic acidemia in recent years in hope of sharing the information on this issue with more people.

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). It is highly aggressive, easy to relapse, and chemotherapy remains its mainstay treatment due to the lack of therapeutic targets. In recent years, many advances have been made in the development of immunotherapy for TNBC. This review summarizes the primary modalities of immunotherapy for TNBC, including immune checkpoint inhibitors, adoptive immune cell therapy, tumor vaccines and oncolytic virus. We present the latest research progress on each treatment from the perspective of clinical study and fundamental research, while introducing the potential predictive biomarkers and resistance mechanisms of immunotherapy for TNBC.
