OBJECTIVETo explore the effect of Peitu Shengjin Recipe (PSR) on nutritional states and immune functions of stable phase chronic obstructive pulmonary disease (COPD) patients.
METHODSTotally 62 stable phase COPD patients were randomly assigned to the treatment group (30 cases) and the control group (32 cases). All patients inhaled Seretide (50/500 µg), twice per day. Besides, patients in the treatment group additionally received PSR, one dose per day. After three months of treatment, the COPD assessment test (CAT) score, the index of nutritional states [including body mass index (BMI) , thickness of skin fold (TSF), mid-arm muscle circumference (MAMC), serum albumin, serum prealbumin], and immune functions (including IgA, IgM, and IgG) were compared between the two groups.
RESULTSBy the end of the treatment, the CAT score decreased more obviously in the treatment group than in the control group (P < 0.05). The improvement of BMI, TSF, MAMC, serum albumin, and serum prealbumin was better in the treatment group than in the control group (P < 0.05). IgM and IgG also increased more in the treatment group (P < 0.05). There was no statistical difference in IgA between the two groups (P > 0.05).
CONCLUSIONSAdditionally use of PSR could improve nutritional states and immune functions of stable phase COPD patients to some extent. Meanwhile, it also could improve their health related quality of life.

ObjectiveTo determine whether antibiotic prophylaxis can reduce the risk of postoperative infective complications in men undergoing transrectal prostatic biopsy (TPB) who had sterile preoperative urine.MethodsMEDLINE, EMBASE, Cochrane Collaboration Reviews, Chinese Medical Current Contents (CMCC), and National Knowledge Infrastructure (CNKI) were searched for rando-mized controlled trials that compared the effect of antibiotic prophylaxis with placebo or active controls for men undergoing TPB with preoperative sterile urine. Two reviewers independently extracted the data of patient characteristics and outcomes based on a prospectively developed protocol.ResultsA total of 12 trials (3 placebo controlled, 3 non-treatment controlled, and 6 activly controlled) involving 1 987 patients, met the inclusion criteria. Prophylactic antibiotic use in patients at low risk undergoing TPB significantly decreased bacteriuria and middle degree fever incidence, but could not decrease the incidence of bacteremia. The relative risk for post-TPB bacteriuria, middle degree fever, and bacteremia were 0.32 (95% CI 0.23 to 0.46), 0.37 (95% CI 0.17 to 0.77), and 0.96 (95% CI 0.61 to 1.50), respectively. Effective antibiotic classes included quinolone, co-quinolone and nitroimidazole, and co-trimethoprim and sulfamethoxazole. Treatment protocols of any duration were effective.ConclusionAntibiotic prophylaxis obviously decreases the incidence of bacteriuria and middle degree fever but not bacteremia in men with preoperative sterile urine undergoing TPB. A significant decrease in bacteriuria incidence can be achieved with a range of antibiotic agents, including quinolones and co-quinolone and nitroimidazole. Treatment protocols of any duration are effective with no heterogeneity.

The silent cerebral infarct is an clinic symptom that is so slight or transitory as to be easily neglected. There are only neural symptoms and signs,but irresponsible infarct focus can be seen on image. The risk factors of silent cerebral infarct may be the same as those of symptomatic cerebral infarct. Such infarct is likely to influence the course, clinic symptom and prognosis of acute cerebral infarct and may foretell symptomatic cerebral infarct and deteriorate into pseudo-global paralysis or multi-infarcted dementia. Therefore elder who suffer from hypertension or diabetes and experience vertigo, headache, language barrier but without apparent signs and symptoms should receive cerebral CT or MRI. Minor or third-degree precautionary measures can be taken as a chief therapy for cerebral infarct. Alternatively vitamines B_6,B_(12) and folic acid can be supplied to reduce the chance of hyperhomocysteinemia. Headache is the initial symptom in silent brain infarct. Magnesium is effective when dehydration does not work.

Asteroid Hyalosis (AH) is a common clinical disease,which has been considered a benign disorder as it rarely impairs visual acuity.It was often discovered when the patient was treated for other eye diseases.The mechanism was unclear.Its characteristic B-ultrasound property makes the B-ultrasound a very helpful diagnostic technique.In the case of the patients with other fundus diseases associated with AH,optical coherence tomography (OCT) and fluorescein angiography (FA) may be used to reduce the interference from asteroid bodies,therefore improve the fundus visibility.Recent studies have shown that AH can incorporate with many other eye diseases.For example,in patients with cataracts,asteroid hyalosis can cause surface calcification of silicone plate intraocular lenses,which in most cases may lead to the need for explantation of the calcified intraocular lenses.The efficacy of pars plana vitrectomy (PPV),the removal of some,or all,of the eye`s vitreous humor for AH remains controversial.In this paper,we provide a review of the recent literature on AH disease: the etiology,diagnosis and treatment.We hope to thus improve the awareness and outcomes of AH disease.

Using the high efficient copper-adsorbing yeast strain Y17 as absorbing material, the major affect factors including pH, original concentration of Cu2+, cell biomass, adsorption time and temperature were examined, and then the absorbing sites of the Y17 was determined. The results showed that the solution pH was the most dominate factor which affected the biosorption of Cu2+, the other affecting factors were the ini- tial concentration of Cu2+, the cell biomass added, and adsorption time, respectively; the temperature had lit- tle effect on the rate of biosorption. The orthogonal experiment showed that the optimal absorption condition was as follow: the solution pH was 5.0, the absorption time was 40 min, the cell biomass of Y17 added was 5.0 g/L, and the concentration of Cu2+ was 8 mmol/L; the highest adsorbing rate was up to 82.7% at this condition. Based on the results of different pretreatments and the desorption of Cu2+, the cell wall of Y17 was identified as the main place occurring boisorption process, and the -NH2 group, -COOH group on the surface of the yeast cells played an important role on the boisorption process.

Abstract: Objective To explore the clinical characteristics of nucleic acid negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicron variant BA. 5.1.3) in Sanya area, and to provide evidence for understanding its clinical characteristics. Methods A retrospective analysis was performed on 14 neonates with negative nucleic acid delivered by pregnant women who tested positive for SARS-CoV-2 (Omicron variant BA.5.1.3) in Sanya Central Hospital (the Third People's Hospital of Hainan Province) from June 2022 to September 2022 (observation group, n=14). The corresponding nucleic acid-negative newborns delivered by pregnant women detected negative with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) were set as the control group (n=56), and the general data and clinical characteristics of neonates in the two groups were compared. Results There was no significant difference between the observation group and the control group in pregnancy diabetes, pregnancy induced hypertension, gestational pre-eclampsia, fetal intrauterine distress, premature rupture of membranes (P>0.05); there was no significant difference between the observation group and the control group in terms of sex, gestational age, birth weight, age, mode of delivery, birth Apgar score, heart screening, pulmonary disease, glucose 6-phosphate dehydrogenase (G6PD) deficiency, thalassemia, breast milk jaundice, hemolytic jaundice (P>0.05). The bilirubin level, blue light irradiation cases and the duration of blue light irradiation of the newborns in the observation group at 7 days after birth were higher than those in the control group (P<0.05); the ratio of blood oxygen saturation ≥ 90% in the observation group was lower than that in the control group (21.43% vs 89.29%, P<0.05), and the ratio of blood oxygen saturation occasionally<90% was higher than that in the control group (57.14% vs 10.71%, P<0.05). The ratio of blood oxygen saturation<90% had no significant difference compared with that in the control group (7.14% vs 0, P>0.05), and the ratio of blood oxygen saturation reduced to the required oxygen uptake was higher than that in the control group (14.29% vs 0, P<0.05). Conclusions The jaundice manifestation of the nucleic acid-negative newborns delivered by pregnant women infected with SARS-CoV-2 (Omicronon variant strain BA.5.1.3) in Sanya area is relatively obvious, with blood oxygen saturation easily lower than 90% and even requiring oxygen inhalation in severe cases.

Abstract: Objective To understand the clinical manifestations, symptoms, treatment and recovery of neonates infected with Omicron variant (BA.5.1.3) of SARS-CoV-2, and provide a certain reference for subsequent diagnosis and treatment of related diseases. Methods The clinical manifestations, epidemiology, auxiliary examinations, and treatment processes of the neonate aged 4-day-old who was community-acquired infection of variant BA.5.1.3 in Sanya was retrospectively analyzed. Results The neonate's mother was identified as a close contact with patients with coronavirus disease 2019 (COVID-19) one hour before delivery, and tested positive for nucleic acid within 24 hours after delivery. But her breast milk, amniotic fluid, placenta, and umbilical cord were not detected for nucleic acid test after delivery. The nucleic acid test of the neonate was negative within 24 hours after birth. Then he was transferred to the hotel for isolation. Before the transfer, the mother and baby stayed in the same room and ate breast milk but the mother did not wear any mask. The neonate didn't have nucleic acid test on the second and third days of his life, and the nucleic acid test of the neonate was positive on the fourth day, negative on the fifth day, and positive on the sixth day. Then he was transferred to the designated hospital of COVID-19 for treatment. The neonate had no cough, no fever, yellow skin, abdominal distension, general breast feeding, and good reaction. On admission, the laboratory examination showed that blood routine examination and electrolyte were normal, and the myocardial enzyme and liver and kidney functions were normal. The bilirubin was significantly increased (449.3 μmol/L). The nucleic acid test of the neonate was positive and his chest imaging results were normal. The treatment measures were mainly isolation, feeding, blue light fading, close monitoring of vital signs, and antiviral drugs were administered. Jaundice subsided and abdominal distension was relieved after 6 d of treatment, and the treatment process was smooth without complications. Conclusions The results suggest that the neonates are susceptible to Omicron variant BA.5.1.3 and prone to aggregation. The evidence of vertical transmission is insufficient and the clinical symptoms of neonates infected with Omicron variant BA.5.1.3 are mid, with no involvement of organ damage of the heart, liver, kidney, brain, and other organs.

Examination reform was explored in Introduction to clinical medicine, and a new evaluation system was constructed which included the combination of formative assessment and sum-mative assessment as well as content system, operation system and monitoring system. The feedback mechanism of formative assessment was put into a full use to improve the teaching effect in this new evaluation system. At the same time, the method of summative assessment was substituted from the traditional closed-book exam to literature translation and presentation carried out by groups. The com-bination of summative assessment and formative assessment could evaluate the teaching efficiency of introduction to clinical medicine more comprehensively and objectively. In addition, it played an ac-tive role in improving students' comprehensive ability and their learning enthusiasm.
