Objective To analyse the pathogeny of pregnancy with virus hepatitis,the change of index of hepatic function and the clinical pathogenetic characteristic,and to explore the relationship between pregnancy and hepatitis.Methods The clinical datas of 96 pregnant patients with virus hepatitis were retrospectively analyzed,and compared with non-pregnancy during the reprodective age in the corresponding period.The pathogeny,index of hepatic function and clinical pathogenetic characteristic were compared.Results Virus hepatitis in the pregnancy were mostly type B hepatits,the morbility of hepatitis increased gradually along with the progress of pregnant weeks,the prothrombin time(PT) significantly prolonged in pregnancy with virus hepatitis,and the albumin decreased significantly,the complications of hepatocerebral disease and hepatorenal syndrome were more than non-pregnancy with virus hepatits,the incidence rate of serious hepatiti was higher than non-pregnancy with virus hepatitis(P

OBJECTIVETo investigate the facial aging analysis of 1200 Han adult people in Dalian with iris diameter, so as to provide reference for facial rejuvenation in Han people.

METHODS1200 facial digital photographs from the second-generation ID card of China were stratified randomly selected as the research sample, excluding facial deformity, tattooing eyebrow, tattooing lid margin, ptosis, lip grain and eyebrow deformity cases, as well as the cases whose join point of upper eyelid and lower eyelid not exposed at the nasal side. These photos were divided into six cohorts: female aged 18, 38, and 68 years old; and male aged 18, 38, and 68 years old, with 200 cases in each cohort. The individual iris diameter was divided into 20 equal parts in each photograph, with each part marked one unit as individual iris diameter ruler. Ten values were made from a horizontal plane between the medial canthus to ten points at one face ( the line between two medial canthus is used as the horizontal line, circumocular and facial soft tissue were measured with individual iris diameter ruler on the photographs), then the results were analyzed with Adobe Photoshop software.

RESULTSThere are statistically significant differences in eyebrow height (36.42 ± 4.22 unit in 18 years old male group, 40.22 ± 6.90 unit in 38 years old male group, 34.83 ± 9.39 unit in 68 years old male group; 37.59 ± 6.72 unit in 18 years old female group, 41.09 ± 5.15 unit in 38 years old female group, 36.84 ± 9.45 unit in 68 years old female group), palpebral fissure height, physiognomic external canthus height, palpebral fissure width, pupil height and other items (P < 0.05).

CONCLUSIONS(1) The brow position rises to the peak level at middle age (38 years old group), then drops down gradually with aging. (2) The physiognomic external canthus moves towards the nasal side and caudal side with aging. (3) Eyeball moves towards caudal side with aging. (4) The soft tissue around bilateral angle of mouth, nasal tip and submaxilla moves towards caudal side with aging. (5) The measurement of individual iris diameter ruler can apply to analyze the aging changes of facial soft tissue, and is more suitable for the case when facial photographs are taken at different distances.

Objective To investigate the effect of platelet-rich plasma(PRP) on starting of AnxA1 gene and PPARγ gene of adipose-derived stem cells (ADSCs) in rabbit.Methods Epididymal adipose tissue stem cells from New Zealand white rabbits,and the cells identified by morphology and inducing differentiation,the cells were cultured to the fourth generation,PRP and PPP (platelet-poor plasma) were prepared by traditional centrifugal method from abdominal aortic of rabbit;ADSCs were cultured in culture medium containing PRP (experimental group),PPP (control group) and all medium (blank group) for each 5％ for 24 h,48h and 72 h.Cells of each group were dissociated and total RNA extracted.AnxA1 gene and PPARγ gene were detected by RT-PCR.Results Primary ADSCs of rabbit grew in the way of long spindle swirly.The results of oil red O and alizarin red staining of the ADSCs were positive.AnxA1 gene and PPARγ gene of experimental group significantly increased from the result of RT-PCR (P＜0.05).Conclusions PRP can promote proliferation of the ADSCs of rabbit and increase the expression of AnxA1 gene and PPARγ gene significantly.

Objective To evaluate the clinical value of a new optic puncture needle designed by our department for renal calculi treatment. Methods There were 8 patients undergoing micro-PCNL with the new device from June 2016 to February 2017. Values of basic demographic data ,operation time ,pain score ,drop in hemoglobin and complications were recorded. Results The mean stone size,operation time,pain score,drop in hemoglobin,and in-hospital time was(21.9 ± 7.3)mm,(43.6 ± 13.6)min,2.8 ± 1.3,7.0 g/L[(133.2 ± 10.3 g/L vs.(123.2 ± 13.9)g/L,P>0.05]and(3.1 ± 1.0)d,respectively. No patient required blood transfusion. Stone-free rate at 1 and 3 months post-operation were 87.5%(7/8)and 100%(8/8),respectively. One suffered urinary tract infections( ClavienⅠ)and was treated with antibiotics. There were no major complications. Conclusion The new device for treatment of renal calculi is feasible and effective.

Objective:To investigate the correlation between hyponatremia and the severity of coronavirus disease 2019 (COVID-19).Methods:Clinical data of 12 patients with COVID-19 admitted to Shantou Central Hospital from January 23 to February 5 in 2020 were retrospectively analyzed, including gender, age, symptoms, lab test and clinical outcomes, to analyze the change trend of blood Na + level in the patients with COVID-19. Results:Among the 12 patients with COVID-19, there were 8 males and 4 females with the mean age of (38.0±16.3) years old, most of them were admitted to the hospital with cough and/or fever. All patients had a positive nucleic acid test for 2019 novel coronavirus (2019-nCoV), and were discharged after clinical treatment with oxygen therapy, antiviral, antibacterial, anti-inflammatory, and nutritional support. All patients were of ordinary type when they were admitted to the hospital. Among them, 1 patient turned into a severe case during the course of the disease, and 1 patient showed a tendency to become severe case. It was found that 10 patients without severe conversion had an average blood Na + of (138.3±1.3) mmol/L at admission, and the lowest blood Na + during the course of disease was (135.9±3.1) mmol/L. However, 2 patients who became severe and had a tendency to become severe disease (Na + levels at admission were 140.0 mmol/L and 138.0 mmol/L, respectively) experienced hyponatremia during the course of the disease (the lowest blood Na + levels were 129.0 mmol/L and 122.0 mmol/L). Further analysis showed that the lower serum Na + level, the higher level of white blood cell count (WBC) and C-reactive protein (CRP), but serum Na + level was consistent with the change trend of lymphocytes, suggesting that hyponatremia was closely correlated with severe inflammation reaction. Conclusions:Serum Na + showed decreasing tendency during the development of COVID-19, and hyponatremia was closely related to the severity of COVID-19. It was necessary to pay great attention to the change trend of blood Na + level. However, further research was needed to obtain more reliable conclusions and explorer the pathophysiological mechanisms.
