The effects of intestinal factor on pulmonary lesion during shock were investigated. Anesthetized rabbits were dividcd at random into SMAO shock group(n=11) and sham shock group (n=8). Occlusion of SMA for 60 min followed by reperfusion produced a significant elevation of pulmonary capillary permeability index (PCPI), an increase of MDA in lung tissue, ultrastructural damage of type Ⅱ pneumocytes, and hyperemia, edema and haemorrhage in alveoli or bronchioli. There was a positive correlation between intestinal mucosal lesion and pulmonary lesion. However, PaO_2 showed no significant declination in this shock model. In vitro, the plasma collected from SMV blood of cats, which had been subjected to SMAO for 90 min, exerted a deleterious effect on isolated perfused rat lungs, characterized by elevation of pulmonary arterial perfusion presure and PCPI, increase in LDH and MDA in the perfusate. These results suggest that the humoral factors released from ischemic intestine into circulation may be, at least partially, accounted for the pulmonary damage during shock.

Objective To investigate the clinical value of wire-guided tubal recanalization under hysteroscope combined with laparoscope for the treatment of occluded oviduct infertility.Methods A total of 63 cases of infertility were diagnosed by hysterosalpingography(HSG) as having bilateral oviduct obstruction,of which at least one side of oviduct was proximally occluded.After laparoscopic exploration and hysteroscopic hydrotubation were performed for clarifying the diagnosis and managing related pelvic lesions,wire-guided tubal recanalization was conducted under hysteroscope combined with laparoscope for the treatment of proximal oviduct obstruction.Results Out of the 63 cases,a total of 118 oviducts were involved(eight oviducts had been previously resected).Of the 118 oviducts,59 were proximally occluded,45 were distally occluded or blinded,and 14 were proximally and distally occluded.After the surgery 99 oviducts were unobstructed.Intrauterine pregnancy was obtained within 1 year in 23 cases(36.6%).There were 25 cases of unpregnancy within 1 year,which were re-examined with HSG,presenting a re-obstruction in 7 cases.Conclusions Wire-guided tubal recanalization under hysteroscope combined with laparoscope is an ideal option for the treatment of occluded oviduct infertility.

Pedicle screw fixation is widely applied to spinal surgery owing to its advantages of maitaining the stability of spine,promoting the bone graft fusing and so on. Remarkably implantation accu-racy is not only closely related to ultimate fixation,but also can affect the incidence and the severity of complications. Consequently,to improve screw implantation accuracy is one of the goals that spinal sur-geons always pursue. In recent years,newly-developed techniques have been preliminarily used in clinic. An overview on the progresses of these techniques in China and overseas is presented here.

The general practice team of the Affiliated Hospital of Hangzhou Normal University and its medical consortium conducted health education for 73 diabetic patients from January to December 2019. The education was dealing with the knowledge and techniques of standardizing insulin administration, including the manipulations, rotation of injection sites and replacement of injection needles, etc. The questionnaire surveys on the knowledge of diabetic management and insulin administration were conducted before and after education. After education the number of patients who knew the injection site and skin disinfection increased from 68 and 69 to 73 and 73, respectively ( P>0.05); the number of patients who knew the injection depth and length of the needle used increased from 33 and 24 to 73 and 73, respectively ( P<0.05); the number of patients who knew pinching the skin, the angle of needle insertion increased from 30 and 44 to 73 and 73 ( P<0.05). After education the number of patients with pinch time>10 sec increased from 0 to 68 cases ( P<0.05); with needle stay>10 sec increased from 0 to 71 ( P<0.05); with rotation in the same area increased from 58 to 73 ( P<0.05); with repeated needle use decreased from 73 to 70 ( P>0.05). After education the blood glucose control of diabetic patients was improved: the glycosylated hemoglobin [(8.3±1.3)% vs. (6.8±0.5)%, t=9.00, P<0.05], fasting blood glucose [(7.7±0.8)mmol/L vs. (6.9±0.5)mmol/L, t=7.90, P<0.05] and 2-hour postprandial blood glucose[(11.4±2.1)mmol/L vs. (9.6±0.8)mmol/L, t=7.00, P<0.05] were significantly decreased. It is suggested that health education provided by the general practice team can standardize the insulin administration in diabetic patients and improve blood sugar control.
