The ossification and development of the spinal column in 194 Chinese fetuseswere studied with radiographic method.Fetal age ranged from 12-35 weeks weredivided into 20 groups.The results were as follows:1.A series of data of longitu-dinal growth of cervical,thoracic,lumbar,sacral and coccygeal regions in differentfetal age groups was obtained,and the regression equations were presented.It ispossible to estimate the length of various regions of vertebral column accuratelyaccording to fetal-age.2.The sequence of development of the primary ossificationcentres in sacral and coccygeal regions was found.The regular pattern will be help-ful to determine the fetal-age and the development of bone.It is confirmed thatthe appearance of ossification centres is earlier in female than that in male.Thereis an existence of sexual difference.3.The total length of the thoracic region isalways the longest while that of the lumbar,cervical and sacral being progressivelyshorter.In comparison with the length of average“vertebral unit”,the lumbar isthe longest,cervical the shortest,thoracic is longer than sacral.During the period of12-35 weeks,the sequence of the length increased is lumbar,thoracic,cervical,andsacral,and comparing with original length,it is also lumbar,thoracic,cervical,andsacral.

The testis and its relative structures of 101 normal male fetuses (fetal-age 12-33 weeks) have been studied in this paper. The results were as follows: 1. The data of fetal growth of testis, epididymis and gubernaculum were given. 2. It has been found that there is no scrotum ligament existed. The gubernaculum is a mesenchyme tissue and is cylindrical pyramid in shape. Objectively, we cannot find any anatomical structure acted as a tractor in testis descending. 3. It has been found that the testis descends in chinese fetus between the 21th and the 25th week of fetal-age. It was completed in all of them after the 26th week. The time is more advanced than that of the traditional conception which referred to be between 7 th and 8 th month. 4. It has been confirmed that once the descent started, the testis run through inguinal canal rapidly. Generally, it seems that the testicular descent in left side is earlier than that in the right. From the above findings, the author suggests that it be necessary to correct the traditional conception in the Chinese anatomy book.

L in ulna and radius.In other long bones.most cases are asymmetrical.This means that the side-difference has been existedduring the fetal life.2.The sex-difference is non-significant during the fetal lifeat the age before 35th week.3.It has been found that the growing speed of limblong bones are different during the different periods of fetal live.It is suggestedthat the growth of fetal limb long bones be divided into two stages:(1)12th-13thweek is a high-speed synchronism stage,the length increased fast and generally theupper limb bones are longer than the relevant lower l(?)mb bones;(2)19th-35thweek is a reduced-speed divergent stage,the growing speed decreased relatively,helower limb long bones are over the upper in length.

The femurs of 98 Chinese fetuses were observed and measured with radiographic method. A series data of femur-length and -width of different fetal-age groups was obtained. Calculated femur index (width/length?100)showed that the proportion between the femural length and the femural width remained considerably constant dur- ing the development of the fetus. The positive correlation between the length of the femur and the C-R length was revealed by statistical analysis; a regression equation was obtained. The authors suggest that it is possible to take the femural length as a criterion parameter to estimate the fetal age.

Objective Three-dimension (3D) cell matrix adhesion in vivo is fundamentally important for a wide variety of cellular physiological and pathological phenomena, however, the cell-matrix 3D adhesion is hardly observed in vitro. We present the human foreskin fibroblasts (HFF) formed 3D adhesion complexes on the thoroughly acellular human amniotic matrix (TAHAM). Methods TAHAM were produced by suspending digestion with trypsin. The HFF were seeded on 6 well plate, matrigel and TAHAM individually.The light microscope, scanning electronic microscope, immunohistochemistry and immunofluorescence were used to observe the micro-structures and detect the type Ⅰ , Ⅲ, Ⅳ, Ⅵ collagen, laminin, fibronectin, TGF-β1, TGF-β2, FGF of the TAHAM. Phase contrast microscope was engaged to observe the morphology of HFF. The time-lapse CCD and the trace analysis software were employed to prescribe the cell migration. The 3D adhesion foci were identified by the laser confocal microscope. The strain of the TAHAM was tested by the universal mechanical testing instrument. Results The fibers of the TAHAM were intact, type Ⅰ , Ⅲ,Ⅳ, Ⅵ collagen, laminin, fibronectin were positive, TGF-β1, TGF-β2, FGF were negative. HFF had a bipolar extension to form multilayer cell clusters networks and grew into the matrix. All of the seeded cells survived three weeks under regular culture without transfer. On TAHAM, HFF moved in a straight line with a speed of 12 μm/h. α5 integrin (green), paxillin (red) and fibronectin (blue) co localized to form 3D adhesion complexes (white). Conclusion The main molecular components and biomechanical properties is preserved in TAHAM. HFF forms 3D adhesion complexes on TAHAM. Cell morphology and migration of HFF on TAHAM correspond to that under 3D adhesion behavior.

Objective To identify Anaplasma species circulating among livestock and rodents from Xitianmu Mountain area in Zhejiang province , Southeastern China and to analyze variations regarding to their 16S rRNA gene.Methods Samples of spleen, liver and blood were collected to extract DNAs .The 16S rRNA gene fragments of Anaplasma species were amplified by using a nested PCR and then sequenced .Ho-mology analysis was conducted by using BLAST program .The multiple sequence alignment and phylogenetic analyses comparing with the sequences of other Anaplasma species in GenBank were conducted by using MEGA 5.0 software.Results The 16S rRNA gene fragments of Anaplasma were detected in 1 cattle, 8 goats, 5 Rattus confucianus, 1 Apodemus agrarius, 1 Berylmys bowersi and 1 squirrel out of 129 animals. The natural infection rate of Anaplasma was 13.2% in animals from Xitianmu Mountain area in Zhejiang . The alignment and phylogenetic analyses indicated that there were at least four Anaplasma species prevalent in livestock and rodents from Xitianmu Mountain area , including Anaplasma phagocytophilum, Anaplasma marginale, Anaplasma centrale and Anaplasma bovis.Moreover, there was a variant that obviously differed from Anaplasmma bovis and other Anaplasma sp.in GenBank.Conclusion The Anaplasma infection was detected among livestock and rodents from Xitianmu Mountain area in Zhejiang province .A newly discovered variant in rodents was likely to be a novel species .More close attention should be paid to Anaplasma infec-tion among human in Xitianmu Mountain area .

Objective To explore the relationship between traditional Chinese medicine (TCM) syndromes of state of evil domination and clinical and laboratory indicators of IgA nephropathy. Methods A prospective study was used to collect data on clinical and laboratory examination of IgA nephropathy in multi clinical centers. Patients’ TCM syndrome types were determined according to the national diagnostic criteria at the same time. Totally 266 patients with IgA nephropathy were included in the study to establish a database for analyzing the relationship between TCM syndrome of state of evil domination and clinical and laboratory indicators. Results In the relationship between syndromes of state of evil domination distribution and clinical subtypes, patients of wind-heat syndrome had more macroscopic hematuria;patients of phlegm-damp syndrome had more nephrotic syndrome;patients of damp-heat syndrome had more chronic nephritis type Ⅰ;patients of blood stasis syndrome had more chronic nephritis type Ⅱ. In the relationship between syndrome of state of evil domination distribution and clinical manifestation, the incidence of hypertension was higher in patients of blood stasis syndrome than in other three types. It was more serious for hematuresis in the patients of wind-heat syndrome. For patients of phlegm-damp syndrome, the incidence of heave proteinuria was highest. In the relationship between syndrome of state of evil domination distribution and laboratory examination, 24-hour urinary protein quantification was higher than in patients of wind-heat and damp-heat syndrome, but the level of blood albumin was lowest. For patients of blood stasis syndrome, serum creatinine level was significantly higher than in other three types;the level of eGFR was just the opposite. The levels of blood cholesterol and triglyceride in patients of phlegm-damp syndrome were higher than in other three types. The activated partial thromboplastin time (APTT) levels in patients of blood stasis and phlegm-damp syndrome were lower than in other patients, but the FIB level was the exact opposite of APTT. In the relationship between syndrome of state of evil domination distribution and the stages of chronic kidney disease (CKD), patients of wind-heat syndrome were more in the first stage of CKD;patients of blood stasis syndrome were more in the third stage of CKD. Conclusion There is relative correlation between TCM syndromes of state of evil domination and clinical and laboratory indicators in IgA nephropathy, which would provide some reference to narrow the gap in the information of the four methods of TCM with clinical and laboratory indicators to enhance accurate diagnosis of TCM syndrome.

Objective    To study the clinical characteristics, therapy strategies and the outcomes of female patients with acute aortic dissection during late pregnancy and puerperal period. Methods    We retrospectively analyzed the clinical data of 7 patients with acute aortic dissection during late pregnancy and puerperal period in Shanghai Changhai Hospital between August 2012 and June 2017. Five of the 7 patients were late stage pregnancy, 2 were puerperal period (1 at the postpartum night, 1 in 18 days after delivery). There were 6 patients of Stanford type A aortic dissection (85.7%), and 1 patient of type B aortic dissection (14.3%). The age of the patients ranged from 26 to 34 (30.8±3.1) years. Cardiac ultrasonography of patients with type A showed that the maximum diameter of the ascending aortas was 4.2–5.7 (4.7±0.6) cm, of which 2 patients were aneurysm of aortic sinus, 3 patients were with Marfan syndrome. Bentall procedure was conducted in 1 patient, Bentall+Sun’s surgery in 2 patients, ascending aorta replacement+Sun’s+coronary artery bypass grafting surgery in 1 patient, aortic root remodeling+ascending aorta replacement+Sun’s surgery in 2 patients. One patient with Stanford type B acute aortic dissection was performed with thoracic endovascular aortic repair (TEVAR) after cesarean section. Results     Aortic blocking time ranged from 51 to 129 (85.5±22.9) min.  Cardiopulmonary bypass time was 75–196 (159.0±44.0) min. Moderate hypothermic circulation arrest with selective cerebral perfusion time was 20–30 (23.8±3.5) min. All maternal and fetuses survived. The infant whose mother received aortic repair in early stage and then received cesarean section was diagnosed with cerebral palsy. Maternal and fetuses were followed up for 9 months to 4 years. During the follow up period, all the fetuses grew well except the cerebral palsy one, and all maternal recovered well. The patient who received aortic repair in the early stage, had a sigmoid rupture during cesarean section and was treated with sigmoid colostomy. Another patient with Stanford type A dissection was diagnosed as left renal vein entrapment syndrome after 2 years. Conclusion    Type A aortic dissection is more common in late pregnancy and puerperal patients. And Marfan syndrome is a high-risk factor for acute aortic dissection in pregnancy women. Early and appropriate surgical treatment strategy based on the type of aortic dissection and gestational age are the key points to achieve good outcomes both for maternal and fetus.

We reported a 54-year-old female patient with severe tricuspid regurgitation, who received mechanic valve in the mitral position 15 years ago. The patient’s Society of Thoracic Surgeons score was 8.27%, and was intolerant to open heart surgery, so she was recommended for transcatheter tricuspid valve replacement via right vena jugularis interna. The procedures were guided by echocardiography and X ray fluoroscopy on November 13, 2021, the prosthesis was implanted successfully, and the patient was recoved without any adverse events. After 1 month follow-up, her general condition was apparently improved.
