The anatomical features of the digestive system in 126 new-born cadavers were examined. In the oral cavity, the palatal ridges on the anterior part of the hard palate were very conspicous. The tongue, in most of the cases, was found to protrude out into the vestibule. This condition was contradictory to most of the textbooks, which state the tongue of the new born infant is short. The pharynx showed usual appearance as in the adult. Its lower end, taking the level of the lower border of the larynx as a land-mark, was at the level of the 4th or 5th cervical vertebra. The distance between the lower margin of the soft palate to the above mentioned level was 3—4 cm. The oesophagus showed no distinct constriction throughout its length. The distance between the upper alveolar process to the cardiac orifice of the stomach was 13—16 cm., being 15 cm. in average. In the majority of cases, the stomach assumed a "J" shape, and its general outline was very much like that of the adult. The liver was relatively large, its weight being 3—4% of that of the body. The umbilical vein when coursing in the left longitudinal fissure of the liver showed a dilation, from which 2—3 branches were given out to the left lobe; 1 or 2 branches to the caudate lobe; 1 to the right lobe after anastomosing with the portal vein. From this anastomotic branch, 1 twig was given to the quadrate lobe. The termination of this vein then became the ductus venosus, much diminished in size, before joining the inferior vena cava. The pancreas was 3—5 gms. in weight. Its course was in front of the left suprarenal gland instead of the left kidney. The small intestine appeared lengthy. No measurement was made on account of the embalmed bodies. A second duodenal papilla was found in 86% of the total cases. The caecum assumed a funnel-shape, lying above the iliac crest in most of the cases. In 3 cases the caecum was observed to be high up under the liver. The vermiform appendix was 3—5 cm. in length, and no valve was found at its orifice. A certain quantity of meconium was found in the lumen of the appendix. The position of the appendix was found to be variable. The taeniae coli were visible. In the majority of cases, neither sacculations nor ap- pendices epiploicae were present. The descending and sigmoid colon were largely distended by the meconium. No visible fat deposition was found in the omentum and mesentery in which the blood vessels and lymph nodes were clearly visible. The great omentum was rather short and extended only 2—3 cm. downwards from the great curvature of the stomach.

Objective: To evaluate the therapeutic effect of gamma knife on patients with intracranial cavernous angioma (CA). Methods: The medical records of 122 patients (134 lesions) who underwent radiosurgery were reviewed retrospectively. Results: hT e average follow-up period was 43 months. No patient died. One patient underwent CA resection. In patients with epilepsy, 83% patients showed alleviation of seizures. About 44% of the lesions shrank in size after treatment with gamma knife radiosurgery (59/134). Seven cases had hemorrhage again after radiosurgery, and the overall annual hemorrhage rate was 1.6%. Edema was found in 11.5% patients (14/122) and all patients showed improvement atf er treatment. Conclusion: Gamma knife is a safe treatment for CA, which could obviously improve the symptoms of epilepsy. Gamma knife radiosurgery is the if rst option for the treatment of cavernous sinus angiomas.

Objective To investigate the relationship between hypoxia and insulin resistance in males with metabolic syndrome ( MS ). Methods Parameters at physical, hematological, glucose metabolism, lipid metabolism, and insulin resistance were measured in 295 middle-aged men who took health examination. The trends of laboratory indexes grouped by hemoglobin quartile and MS components were compared. The correlation between hypoxia and insulin resistance was analyzed. Results With the increase of hemoglobin, the occurrence rates of MS, TG, INS, and HOMA-IR were also significantly increased ( P < 0. 05 ), while HDL-C and HOMA-IS reduced remarkably(P<0. 05). With the increase of MS components, hematological parameters(RBC, Hb, Hct), INS, and HOMA-IR were significantly increased( P<0. 05) while HOMA-IS were significantly decreased( P<0. 05). Blood lactate and HIF-1αwere significantly increased with the increase of hemoglobin as well as MS components(P<0. 05);Hematological parameters were positively correlated with blood lactate and HIF-1α, and Hypoxia related indicators including hematological parameters, Lac, HIF-1α showed a positive correlation with HOMA-IR and a negative correlation with HOMA-IS( P < 0. 05). Conclusion Chronic hypoxia does exist in metabolic syndrome, and the degree of hypoxia is associated with insulin resistance. Hematological parameters are also significantly correlated with insulin resistance which could be as a result of chronic hypoxia.

Objective:To investigate whether knee osteoarthritis has an impact on the patient′s depression and whether it′s progression will affect the patient′s depression, and to provide a reference for clinical work.Methods:Patients diagnosed with osteoarthritis in Dalian Central Hospital from 2016 to 2019 were divided into 4 groups according to Kellgren-Lawrence staging, and the patients were scored on WOMAC scale, AKSS clinical scale, and AKSS. The score of the scale and the score of the HAMD scale were collected and statistically analyzed using SPSS 17.0.Results:χ2 test was used to show that there was no difference in the gender composition of patients in different stages ( P<0.05). The AKSS clinical scale score, AKSS functional scale score, WOMAC scale score and HAMD scale score were statistically analyzed for each stage. The results showed that the average AKSS clinical scores of patients in each stage were as follows: stage Ⅰ: (90.01 ± 8.41) points; stage Ⅱ: (79.98 ± 10.93) points; stage Ⅲ: (71.78 ± 13.64) points; stage Ⅳ: (54.18 ± 12.58) points. The AKSS functional scores were as follows, stage Ⅰ: 100 points; stage Ⅱ: 80 points; stage Ⅲ: 70 points; stage Ⅳ: 45 points; the average WOMAC scale scores of patients in each stage were as follows, stage Ⅰ: (28.69 ± 19.22) points ; stage Ⅱ: (49.43 ± 22.69) points; stage Ⅲ (70.13 ± 24.84) points; stage Ⅳ: (107.79 ± 24.39) points. The average HAMD scale scores of patients in each stage were as follows, stage Ⅰ: (4.89 ± 3.42) points; stage Ⅱ: (7.65 ± 4.20) points; Stage Ⅲ: (9.05 ± 5.03) points; stage Ⅳ: (12.35 ± 5.41) points. The analysis showed that there were significant statistical differences in the scale scores between each period ( P<0.05). There was a correlation between the patient′s depression status and the patient′s age, pain, and joint function, and there were statistical differences ( P<0.05). Conclusions:There is a significant correlation between depression and pain and function in patients with knee osteoarthritis. The progress of the osteoarthritis course will aggravate the patient′s depression state. Conversely, the patient′s depression state can also aggravate the symptoms of osteoarthritis patients and affect the clinical efficacy of the patients.
