Genetic factors play an important role in the development of Alzheimer's disease (AD). This article mainly introduced some genes, which have been reported in recent years, predisposing to different aspects of AD. The occurrence and progress of the late onset Al-zheimer's disease (LOAD) can be better understood through further study of the susceptibility loci, especially by using the pathway analysis, and the important hub genes can be found so as to provide targets for clinical prevention, diagnosis and treatment. Due to the dispersion of genetic variant information, it needs detailed literature, online search and some bioinformatics methods to analyze the causative genes and signaling pathways related to LOAD. 3 databases were took as recourses, and they were analyzed with multi-means and multi-ways of analy-sis and data mining methods, in order to provide theoretical basis for further study and clinical treatment of AD genetics.

Objective To clarify the role of the known genes and new discovered genes, which were important to the pathogenesis of Alzheimer's disease (AD), in order to provide targets for clinical prevention, diagnosis and treatment. Methods In order to predict AD susceptible genes, the website databases (OMIM, AlzGene) and a variety of pathogenic gene prediction tools such as Endeavour, Gene Prospector, GLAD4U and ProphNet were used to make biological analysis. Results Disease-causing genes were directly obtained from the OMIM and Alzgene databases, and related genes were collected by 4 kinds of tools (select gene whose frequency was 3 or more). The data were shared and a list of 25 genes was gotten. These genes were CALHM1、 ABCA7、 A2M、 CLU、 SORL1、 HFE、 CD2AP、 APP、 ACE、 PICALM、 APOE、 NOS3、 MS4A6A、 PLD3、 CR1、 ADAM10、 MS4A4E、 BLMH、 PSEN1、 CD33、 PSEN2、 MPO、 APBB2、 BIN1 and PLAU. Conclusion CALHM1, ABCA7, A2M and CLU, etc., have a certain correlation with AD, which provide theoretical basis for further research of AD genics and clinical treatment.

Objective To analyze the possible reasons of failed surgical treatment of acetabular fractures. Methods Various methods were used for positive patient identification, including according to Matta's X-ray assessment and Merle d'Aubigne & Postel hip function score of clinical standards for classification of acetabular fracture reduction surgery were not satisfied or not carried out a reduction and fixation,the clinical evaluation of hip joint as a "bad", occurrence of femoral head subluxation or dislocation, femoral head necrosis and other serious complications. From February 2000 to February 2008, 22 patients including 14 males and 8 females with an average age of 38.6 years (range, 18-72 years) were considered as failed cases. Results 45.5% of these cases were posterior wall fractures which were not given any fixation, 27.3% of them were posterior column fractures which were not fixed, 13.6% of them whose reduction and fixation of anterior wall fractures were not satisfied, and 9.1% of them were anterior column fractures which needed fixation. One case should take open reduction and iternal fixation instead of THA. The rate of misdiagnosis and mistaken diagnosis were 90% if only X-ray evaluation was made and this rate decreased to 8.3% if computed tomography was taken. The rate of wrong selection of operative approach was 100% in 10 cases of misdiagnosis, and which was 58.3% in 12 cases of correct diagnosis. In the 5 patients with correct diagnosis and selection of operative approach, the reasons of failed surgical treatment were due to imperfect surgical skills in 3 cases, and inappropriate fixation patterns in 2 cases. Conclusion The causes of the failure of surgical treatment for acetabular fracture might include preoperative missed diagnosis and misdiagnose, inappropriate approach, and an unreasonable internal fixation with unskillful technique.

OBJECTIVES:
The main treatment for intrauterine adhesion (IUA) is hysteroscopic adhesiolysis (HA), which most of treatment frequently employs estrogen and progesterone cycle therapy. The growth and coverage of endometrium after operation is a difficult problem, and several hospitals in China have performed growth hormone (GH) in empirically treating IUA, which has achieved excellent curative effects. Unfortunately, the mechanism of action has not yet been clearly elucidated. In previous study, an IUA animal model after surgical abortion and curettage in pregnant rats has been successfully established. In this experiment, the IUA animal model after surgical abortion and curettage in pregnant rats, which is more in line with the mechanism of human intrauterine adhesion, was used for the first time to investigate the therapeutic effect of GH on IUA in the pregnant rat curettage model. The expression of signal transducers and activators of transcription 3(STAT3), phosphorylated STAT3 (p-STAT3), STAT5 and p-STAT5 content were detected by immunohistochemistry to preliminarily explore the possible mechanism of GH involving in promoting endometrial growth of IUA, and to provide a theoretical basis for clinical medication and treatment.
METHODS:
Pregnant rats were anesthetized, and the bilateral embryos were removed completely. Then the rat endometrium was scraped with a curette in 4 different directions (front, back, left, and right). After the IUA animal model was established, the rats were randomly divided into 3 groups (n=5): a control group, a GH group, and a GH + AG490 group. Normal saline (0.4 mL/100 g) was injected subcutaneously at the 7th day after curettage in the control group;0.15 U/100 g of GH was injected subcutaneously at the 7th day after curettage in the GH group; 0.15 U/100 g of GH was injected subcutaneously and 1 mg/100 g AG490 was injected intraperitoneally at the 7th day after curettage in the GH+ AG490 group. All the rats were injected continuously for 5 days. The rats in each group were sacrificed at the 14th day. The uterus of rats in each group was stained with HE staining to explore the endometrial morphology and the number of endometrial glands in each group, and Masson staining was utilized to observe the degree of endometrial fibrosis. The levels of STAT3, p-STAT3, STAT5 and p-STAT5 were detected by immunohistochemistry.
RESULTS:
1) The number of glands in the GH group was more than that in the control group on the 14th day, with statistical difference (P<0.05). However, the number of endometrial glands in the AG490+GH group was decreased compared with the GH group on the 14th day (P<0.05). 2) The fibrosis ratio in the GH group was less than that in the control group at the 14th day after operation (P<0.05). However, the area of endometrial interstitial fibrosis in the AG490+GH group was much higher than that in the GH group 14 days after operation (P<0.05). 3) Compared with the control group, there was not significant difference in the levels of STAT3 and STAT5 in GH group (both P>0.05), while the levels of protein p-STAT3 and p-STAT5 were increased in the GH group (both P<0.05). Compared with the GH group, there was not significant difference in the levels of STAT3 and STAT5 in the AG490+GH group (both P>0.05), while the levels of p-STAT3 and p-STAT5 were decreased in the AG490+GH group (both P<0.05).
CONCLUSIONS
GH can not only promote the growth of endometrial glands in the IUA model, but also reduce the degree of fibrosis and play a role in the treatment of IUA, which may be related to the activation of the Janus kinase (JAK), JAK/STAT3 and STAT5 signaling pathways.

Journal of Central South University(Medical Sciences) 2022;47(11):1479-1486
The septate uterus is the most common structural uterine anomalies and it is associated with the poor reproductive outcome. It is believed to be the result of the failure in resorption of the tissue connecting the 2 paramesonephric ducts prior to the 20th embryonic week. The true prevalence of uterine septum is difficult to ascertain, as many uterine septal defects are asymptomatic. The septate uterus is usually diagnosed during an infertility evaluation and affects reproductive health by impairing fertility and increasing adverse pregnancy outcomes. The variations in uterine and cervical/vaginal anomalies collectively referred to as Müllerian anomalies. No consistent gold standard for the diagnosis of Müllerian anomalies exists. The preferred diagnostic method for Müllerian anomalies is two-dimensional ultrasound, other methods such as three-dimensional ultrasound, magnetic resonance imaging, hysterosalpingo contrast sonography, hysterosalpingography, hysteroscopy, and laparoscopy are also used to improve accuracy.

Although there is insufficient evidence supporting the link between septate uterus and infertility, there are many studies demonstrated the effect of spetal incision on pregnancy in women diagnosed with septate uterus associated with infertility. Hysteroscopic metroplasty can significantly improve the reproductive performance of those with septate uterus. Some Müllerian malformations can be healed by surgery. The accurate diagnosis and appropriate therapeutic approch are fundamental for successful treatment. Any attempt at surgical correction of uterine abnormalities must be aimed at preserving or improving reproductive function. Among congenital uterine anomalies, septate uterus is the most amenable to simple hysteroscopic treatment. The resection of the septum is performed as standard treatment worldwide.

OBJECTIVES:
Hysteroscopic adhesiolysis (HA) remains the mainstay on treatment for intrauterine adhesions (IUA). The fertility outcome of patients with moderate and severe intrauterine adhesions after HA is still far from satisfactory. Estrogen combined with progesterone is the most common treatment; however, they do not help in improving the fertility rate to the maximum because of the limitations. This retrospective, non-randomized controlled study will assess the effects of traditional Chinese medicine Yangmo decoction after HA in restoration of the endometrium and improvement of the fertility rate.
METHODS:
A total of 427 patients, who met the inclusion criteria, aged between 20 and 45 years and diagnosed with moderate or severe IUA underwent HA at the Third Xiangya Hospital from January to August 2021, were enrolled for this study. Participants were assigned into 2 groups: A Yangmo decoction group (n=213, patients were given Yangmo decoction consisting of Ginseng flower, Sanchi flower, Daidai flower, Snow lotus, Licorice and so on after HA), and an estrogen and progesterone group (n=214, patients were given estrogen and progesterone after HA). The following basic information was collected retrospectively for both groups, including age, parity, history of abortion, menstrual status, and times of hysteroscopic interventions. American Fertility Society (AFS) score was used by a senior surgeon and the density of opening of endometrial glands was evaluated during HA. The parameters were obtained from three-dimensional transvaginal ultrasound (3D-TVUS) preoperatively and postoperatively, to evaluate the efficacy of Yangmo decoction, estrogen, and progesterone. All patients were followed up on telephone to determine the fertility rate until 6 months from the last HA.
RESULTS:
Based on the basic information collected preoperatively, there were no significant differences between the groups (all P>0.05). Postoperatively, patients in the Yangmo decoction group had a better surgical success rate with a more significant AFS reduction (P<0.001), better density of opening of endometrial glands in the uterine cavity (P<0.000 1) after HA, and a better fertility rate (40.4%) in the time of 6 months after the last HA than those of the estrogen and progesterone group.
CONCLUSIONS
Yangmo decoction has better therapeutic efficacy in the treatment of intrauterine adhesion after HA than the combined effect of estrogen and progesterone. Yangmo decoction helps restore the endometrium and improve the fertility rate, therefore, it can be adopted as a routine practice for IUA patients who have fertility requirements.
