BACKGROUND: The minimal latency and conduction velocity of F-wave have been widely used for the detection of varied neurological disorders,whereas the significance and the diagnostic value for the other parameters of F wave are seldom reported. How sensitive are these parameters in the earlier evaluation of diabetic peripheral neuropathy (DPN) ?OBJECTIVE: To investigate the evaluating value of F-wave parameters for the earlier DPN, providing references for earlier clinical rehabilitative intervention.DESIGN: Case-control study with type 2 diabetic patients and health people as subjects.SETTING: The wards and outpatients in the Departments of Neurology and Endocrinology, Renmin Hospital of Wuhan University.PARTICIPANTS: Between January 1999 and December 2000, there were totally 106 patients with type 2 diabetic mellitus(DM) at the wards and outpatients in the department of neurology and endocrinology in Renmin Hospital of Wuhan University, including 64 males and 42 females, with the average age of (55 ± 13) years and the average DM course of (10.2 ± 4. 8)years. Meanwhile, 75 healthy volunteers were enrolled in the control group,including 45 males and 30 females, with the mean age of(54 ± 12) years.Two groups were matched in age and leg length( P ＞ 0. 05).INTERVENTIONS: Using Nicolet Viking-Ⅳ, F wave and M-wave parameters of tibial nerve stimulation were analyzed.MAIN OUTCOME MEASURES: The minimum latency (Fmin), duration (Fdur), amplitude(Famp) and area(Farca) of F wave; and the amplitude (Mamp)and aera(Marea) of M-wave.neuropathy( n = 30), there were 8 cases(the abnormal rate being 27% ) with increased Fdur, 4(13% ) with prolonged Fmin and 2(7% ) with increased F/Mamp and F/Marea increased significantly in the patients with DPN( n = 76).mality rate of Fdur was significantly higher (96% vs 21%, P ＜0.01), the abnormality rate of Fmin was significantly lower(51% vs 76%, P ＜ 0.05 ) and there were no significant difference of other parameters( P ＞ 0.05) in the patients with mild DPN subgroup ( n = 47).diagnostic parameter for earlier DPN, and therefore detect the sub-clinical DPN, and the proximal may be earlier involved than the distal.

Objective To evaluate the effects of the serum of patients with obstructive jaundice on myogenic differentiation of human pulmonary microvascular endothelial cells (PMVECs). Methods Hu?man PMVECs were isolated and then subcultured. The cultured PMVECs were incubated with the serum of patients with obstructive jaundice or with the serum of healthy volunteers. At 24, 48 and 72 h of incubation (T1?3), the inverted microscope was used to observe the morphology of primary PMVECs. The expression of muscular proteins ( alpha?smooth muscle actin [α?SMA ] , smooth muscle?mysion heavy chain [ SM?MHC] , capolnin) in PMVECs was detected using Western blot analysis. Results The expression of cal?ponin andα?SMA was negative, and a few SM?MHC proteins were expressed when PMVECs were incubated with the serum of healthy volunteers; the expression of calponin, α?SMA and SM?MHC was positive when PMVECs were incubated with the serum of patients with obstructive jaundice. Compared with the serum of healthy volunteers, the expression of SM?MHC was significantly up?regulated when PMVECs were incubated with the serum of patients with obstructive jaundice (P<0.05). The expression of calponin, α?SMA and SM?MHC was significantly up?regulated at T2,3 compared with that at T1 , and at T3 compared with that at T2 when PMVECs were incubated with the serum of patients with obstructive jaundice ( P<0.05) . Conclusion The serum of patients with obstructive jaundice promotes myogenic differentiation of human PMVECs, which is probably one of the mechanisms underlying intrapulmonary microvascular dilatation.

Objective:To explore the effect of early quantitative pulmonary rehabilitation assessment in adult Intensive Care Unit (ICU) patients with mechanical ventilation in high altitude area.Methods:From March 2019 to October 2021, convenience sampling was used to select 287 adult ICU patients with mechanical ventilation of Qinghai Red Cross Hospital as the research object. According to the time of admission, the patients were divided into the control group (142 cases) and the experimental group (145 cases) . The control group was given the routine pulmonary rehabilitation, and the experimental group received the early pulmonary rehabilitation based on quantitative assessment. The Acute Physiology and Chronic Health EvaluationⅡ (APACHEⅡ) score and the Intensive Care Units Mobility Scale (IMS) score were compared between the two groups before enrollment, on the eighth and sixteenth days of pulmonary rehabilitation. The oxygenation index of the two groups of patients before enrollment and on the first, fourth, sixth, eighth and sixteenth days of pulmonary rehabilitation, the time of ICU stay, the time of mechanical ventilation, the success rate of ventilator removal and the complications of the two groups of patients with mechanical ventilation were also compared.Results:On the eighth and sixteenth days of pulmonary rehabilitation, the APACHE Ⅱ score of the experimental group was lower than that of the control group, and the IMS score was higher than that of the control group, with statistical differences ( P<0.05) . On the sixth, eighth and sixteenth days of pulmonary rehabilitation, the oxygenation index of the experimental group was higher than that of the control group, and the difference was statistically significant ( P<0.05) . The ICU stay time and mechanical ventilation time in the experimental group were lower than those in the control group, and the success rate of ventilator removal in the experimental group was higher than that in the control group, with statistical differences ( P<0.05) . Conclusions:Implementing early pulmonary rehabilitation for adult ICU patients with mechanical ventilation in high altitude area is conducive to promoting pulmonary rehabilitation of patients, improving the success rate of ventilator removal, and reducing patients' ICU stay time, mechanical ventilation time and the occurrence of complications.
