OBJECTIVE: To compare the clinical efficacy of acupuncture, Chinese medication and combination of acupuncture and medication in the treatment of dry eye complicated with computer vision syndrome (CVS). METHODS: A total of 152 patients with dry eye complicated with CVS were randomly divided into an acupuncture-medication group (38 cases, 1 case was removed), an acupuncture group (38 cases, 1 case dropped off), a Chinese medication group (38 cases, 1 case was removed), and a western medication group (38 cases, 1 case dropped off). In the western medication group, sodium hyaluronate eye drop combined with esculin and digitalis glycosides eye drop were used. In the acupuncture group, acupuncture was applied at bilateral Taiyang (EX-HN 5)， Cuanzhu (BL 2), Fengchi (GB 20), Qimen (LR 14) , and Hegu (LI 4) etc., once a day. In the Chinese medication group, Yiqi Congming decoction formula ganule was given orally, one dose a day. In the acupuncture-medication group, acupuncture combined with Yiqi Congming decoction formula granule were used. All groups were treated for 14 d. The non-invasive first tear film break-up time (NIBUT f), non-invasive average tear film break-up time (NIBUT av), tear meniscus height (TMH), ocular surface disease index (OSDI) score, and CVS symptom score were compared between the patients of each group before and after treatment. RESULTS: After treatment, the NIBUT f, NIBUT av, and TMH were increased compared with those before treatment in the patients of the 4 groups (P<0.01); the NIBUT f and NIBUT av in the acupuncture-medication group and the acupuncture group were higher than those in the Chinese medication group and the western medication group (P<0.05), and the TMH in the acupuncture-medication group and the Chinese medication group were higher than those in the acupuncture group and the western medication group (P<0.05). After treatment, the OSDI scores, the various scores and total scores of CVS (except for head symptom score in the western medication group) were decreased compared with those before treatment in the patients of the 4 groups (P<0.01). The OSDI score, total score, eye symptom score, and body symptom score of CVS in the acupuncture-medication group were lower than those in the acupuncture group, the Chinese medication group, and the western medication group (P<0.01, P<0.05), the head symptom score of the acupuncture-medication group was lower than that in the western medication group (P<0.05), and the CVS physical symptom scores and mental cognitive symptom scores of the acupuncture-medication group and the acupuncture group were lower than those in the Chinese medication group and the western medication group (P<0.05). CONCLUSION Acupuncture has advantages in improving NIBUT f, NIBUT av, and CVS physical symptoms and cognitive symptoms, and the Chinese medication has advantage in improving TMH. The combination of acupuncture and Chinese medication has better effects compared with monotherapy.

Peritoneal ultrafiltration failure is a common reason for peritoneal dialysis (PD) withdrawal as well as mortality in PD patients. Based on the three-pore system, inter-cellular small pores and trans-cellular ultra-small pores (aquaporin-1) are mainly responsible for water transfer across the peritoneum. Both small and ultra-small pores-dependent water (free water) transport decline accompanied with time on PD, with more significant decrease in free water, resulting in peritoneal ultrafiltration failure. The reduction of free water transport is associated with fast peritoneal solute transfer, reduced crystalloid osmotic gradient due to increased interstitial glucose absorption, and declined osmotic conductance to glucose resulted from impaired aquaporin-1 function and peritoneal interstitial fibrosis. The decline of small pore-based water is mainly because of fast loss of crystalloid osmotic gradient, decrease of hydrostatic pressure mediated by peritoneal vasculopathy, as well as reduced absolute number of small pores. The current review discusses the advance on pathogenesis of acquired peritoneal ultrafiltration failure in long-term PD.

OBJECTIVE: To investigate the incidence and risk factors of hypothermia in patients with acute renal injury (AKI) receiving continuous renal replacement therapy (CRRT), and to compare the effects of different heating methods on the incidence of hypothermia in patients with CRRT. METHODS: A prospective study was conducted. AKI patients with CRRT who were admitted to the department of critical care medicine of the First Affiliated Hospital of Wannan Medical College (Yijishan Hospital) from January 2020 to December 2022 were enrolled as the study subjects. Patients were divided into dialysate heating group and reverse-piped heating group according to randomized numerical table method. Both groups were provided with reasonable treatment mode and parameter setting by the bedside physician according to the patient's specific condition. The dialysis heating group used the AsahiKASEI dialysis machine heating panel to heat the dialysis solution at 37 centigrade. The reverse-piped heating group used the Barkey blood heater from the Prismaflex CRRT system to heat the dialysis solution, and the heating line temperature was set at 41 centigrade. The patient's temperature was then continuously monitored. Hypothermia was defined as a temperature lower than 36 centigrade or a drop of more than 1 centigrade from the basal body temperature. The incidence and duration of hypothermia were compared between the two groups. Binary multivariate Logistic regression analysis was used to explore the influencing factors of hypothermia during CRRT in AKI patients. RESULTS: A total of 73 patients with AKI treated with CRRT were eventually enrolled, including 37 in the dialysate heating group and 36 in the reverse-piped heating group. The incidence of hypothermia in the dialysis heating group was significantly lower than that in the reverse-piped heating group [40.5% (15/37) vs. 69.4% (25/36), P < 0.05], and the hypothermia occurred later than that in the reverse-piped heating group (hours: 5.40±0.92 vs. 3.35±0.92, P < 0.01). Patients were divided into hypothermic and non-hypothermic groups based on the presence or absence of hypothermia, and a univariate analysis of all indicators showed a significant decrease in mean arterial pressure (MAP) in hypothermic patients (n = 40) compared with the non-hypothermic patients [n = 33; mmHg (1 mmHg ≈ 0.133 kPa): 77.45±12.47 vs. 94.42±14.51, P < 0.01], shock, administration of medium and high doses of vasoactive drug (medium dose: 0.2-0.5 μg×kg^-1×min^-1, high dose: > 0.5 μg×kg^-1×min^-1) and CRRT treatment were significantly increased [shock: 45.0% (18/40) vs. 6.1% (2/33), administration of medium and high doses of vasoactive drugs: 82.5% (33/40) vs. 18.2% (6/33), administration of CRRT (mL×kg^-1×h^-1): 51.50±9.38 vs. 38.42±10.97, all P < 0.05], there were also significant differences in CRRT heating types between the two groups [in the hypothermia group, the main heating method was the infusion line heating, which was 62.5% (25/40), while in the non-hypothermia group, the main heating method was the dialysate heating, which was 66.7% (22/33), P < 0.05]. Including the above indicators in a binary multivariate Logistic regression analysis, it was found that shock [odds ratio (OR) = 17.633, 95% confidence interval (95%CI) was 1.487-209.064], mid-to-high-dose vasoactive drug (OR = 24.320, 95%CI was 3.076-192.294), CRRT heating type (reverse-piped heating; OR = 13.316, 95%CI was 1.485-119.377), and CRRT treatment dose (OR = 1.130, 95%CI was 1.020-1.251) were risk factors for hypothermia during CRRT in AKI patients (all P < 0.05), while MAP was protective factor (OR = 0.922, 95%CI was 0.861-0.987, P < 0.05). CONCLUSIONS AKI patients have a high incidence of hypothermia during CRRT treatment, and the incidence of hypothermia can be effectively reduced by heating CRRT treatment fluids. Shock, use of medium and high doses of vasoactive drug, CRRT heating type, and CRRT treatment dose are risk factors for hypothermia during CRRT in AKI patients, with MAP is a protective factor.

Local inflammatory reaction and microcirculation disturbance are the early manifestations of acute pancreatitis (AP). Studies have shown that early and reasonable fluid resuscitation of patients with AP can reduce related complications and prevent the deterioration to severe acute pancreatitis (SAP). Traditional isotonic crystalloid (such as Ringer solution) is considered to be a safe and reliable resuscitation solution, but too much and too fast infusion in the early stage of shock will increase the risk of complications such as tissue edema and abdominal compartment syndrome (ACS). Many scholars have found that hypertonic saline resuscitation solution has the advantages of reducing tissue and organ edema, rapidly restoring hemodynamics, inhibiting oxidative stress and inflammatory signal transduction, thereby improving the prognosis of AP patients and reducing the incidence of SAP and mortality. This article summarizes the mechanisms of hypertonic saline in the resuscitation treatment of AP patients in recent years, in order to provide reference for the clinical application and research of AP patients.

Foam stability affects the efficacy and incidence of side effects of foam sclerotherapy. Exploring the relationship between foam pressure difference and foam stability can provide ideas and basis for obtaining more stable foam. In the experiment, sodium cod liver oleate foam was selected, and poloxamer 188 (concentration of 0%, 4%, 8%, 12%) was added to realize the change of foam pressure. By using the self-written program to process the foam pictures, the foam pressure difference and the relationship between the foam stability indicators (water separation rate curve, half-life) and the foam pressure difference were obtained. The results showed that at first the foam pressure increased with the increase of the concentration, and then it decreased with the increase of the concentration and reached a peak at the concentration of 4%. The foam pressure difference decreases continuously with the increase of decay time. When the additive concentration is low, the foam average pressure difference increases. And if the additive concentration is too high, the foam average pressure difference decreases. The smaller the foam pressure difference is, the better the foam stability is. This paper lays a foundation for the research on the stability of foam hardener.

Fluid resuscitation is an essential intervention in critically ill patients, and its ultimate goal is to restore tissue perfusion. Critical illnesses are often accompanied by glycocalyx degradation caused by inflammatory reactions, hypoperfusion, shock, and so forth, leading to disturbed microcirculatory perfusion and organ dysfunction. Therefore, maintaining or even restoring the glycocalyx integrity may be of high priority in the therapeutic strategy. Like drugs, however, different resuscitation fluids may have beneficial or harmful effects on the integrity of the glycocalyx. The purpose of this article is to review the effects of different resuscitation fluids on the glycocalyx. Many animal studies have shown that normal saline might be associated with glycocalyx degradation, but clinical studies have not confirmed this finding. Hydroxyethyl starch (HES), rather than other synthetic colloids, may restore the glycocalyx. However, the use of HES also leads to serious adverse events such as acute kidney injury and bleeding tendencies. Some studies have suggested that albumin may restore the glycocalyx, whereas others have suggested that balanced crystalloids might aggravate glycocalyx degradation. Notably, most studies did not correct the effects of the infusion rate or fluid volume; therefore, the results of using balanced crystalloids remain unclear. Moreover, mainly animal studies have suggested that plasma may protect and restore glycocalyx integrity, and this still requires confirmation by high-quality clinical studies.

OBJECTIVE: On the basis of sodium hyaluronate eye drops, to observe the clinical efficacy of acupuncture on dry eye and explore the effect mechanism of ocular surface protection. METHODS: A total of 80 patients with dry eye were randomly divided into an observation group and a control group, 40 cases in each group. The control group was treated with routine cleaning of eyelid margin, hot compress of eyes with warm towel, and external application of sodium hyaluronate eye drops for 5 weeks. On the basis of the treatment as the control group, the observation group was treated with acupuncture at Jingming (BL 1), Cuanzhu (BL 2), Chengqi (ST 1), Hegu (LI 4), Zusanli (ST 36), Sanyinjiao (SP 6), etc., once a day, 6 times a week for 5 weeks (30 times totally). Before and after treatment, SchirmerⅠtest (SⅠT), breaking up time (BUT), corneal fluorescent (FL) score, ocular surface disease index (OSDI) score, and the contents of IL-6 and TNF-α in tears were evaluated and the therapeutic effect was compared between the two groups. RESULTS: Compared with before treatment, SⅠT and BUT after treatment in the observation group were prolonged (P<0.05), the scores of FL and OSDI and the contents of IL-6 and TNF-α in tears were decreased (P<0.05). After treatment, SⅠT and BUT in the observation group were longer than the control group (P<0.05), and the scores of FL and OSDI and the contents of IL-6 and TNF-α in tears in the observation group were lower than the control group (P<0.05). The total effective rate in the observation group was 87.5% (35/40), which was higher than 45.0% (18/40) in the control group (P<0.05). CONCLUSION On the basis of sodium hyaluronate eye drops, acupuncture could improve the clinical symptoms of dry eye, promote the secretion of tears, prolong the tear film breaking up time, and reduce corneal damage, and effect mechanism may be related to the reduction of inflammatory response.

Objective: To determine the characteristics and progress of the visual acuity and refractive state of schoolchildren in Huangzhong District, Xining City, Qinghai Province in China. Methods: Cohort study. Department of Ophthalmology, Beijing Children's Hospital carried out a cohort study by collecting the visual acuity and refractive state of Grade 1-5 schoolchildren among 16 primary schools in Huangzhong District, Xining City, Qinghai Province in September 2020 and July 2021. Cycloplegic retinoscopy with eye drop which contained tropicamide (0.5%) and phenylephrine hydrochloride (0.5%) was performed in children with low vision(<1.0). Myopia was defined as the spherical equivalent (SE) ≤-0.5 D after cycloplegic retinoscopy. Measurement data was analyzed by t-test and enumeration data was analyzed by χ² test. Multiple linear regression was used to analyze the influencing factors. Results: The 2 489 individuals with repeated tests in two years were included in the follow-up study, among whom the prevalence of myopia was 26.24%(653/2 489) in 2020, while 32.94% (820/2 489)respectively in 2021. The incidence of myopia in one school year from grades 1 to 5 was 11.19%(47/420), 5.44%(21/386), 6.39%(25/391), 11.52%(44/382) and 11.67%(30/257). The average SE of children in all grades in 2021 increased negatively from the previous year (Grade 1 to Grade 5 increased respectively: 0.40 D, 0.69 D, 0.62 D, 0.52 D and 0.37 D). Conclusions: The prevalence of myopia among schoolchildren in Huangzhong District, Xining City, Qinghai Province was relatively high. There were two peaks of myopia incidence in the first, fourth and fifth grades. Female, age, and the baseline of SE were the related influencing factors for myopia progression.
