Objective To discuss different effect of periocular injection and subconjunctival injection in treatment of iridocyclitis. Methods Eighty people with iridocyclitis were divided into group A and group B according to their admission order. Group A adopted periocular injection and group B was given subconjunctival injection. The incidence of complication was compared between the two groups. Results Significant difference existed in complications and related factors between two groups after treatment, periocular injection proved to be superior to subconjunctival injection. Conclusions Periocular injection is a desirable treatment method for iridocyclitis. It is easy to operate, safe, rapid and with less pain, so it is worthy of clinical application.

Objective To compare the measured IOP values by non-contact tonometer and indentation tonometer in order to evaluate the non-contact tonometer in clinical application. Methods 320 eyes of 160 patients for screening of IOP in the clinic were included in the observation, by self-control study, the IOP value of the non-contact tonometer(abbreviated NCT) and the indentation tonometer was compared. Results IOP values measured by NCT was lower than that mesgured by indentation tonometer. Conclusions IOP values measured by NCT was lower than that measured by indentation tonometer, for IOP value around 2.67 kPa measured by NCT, it is best to use indentation tonometer to retest or coming again for subsequent visit.

Objective To investigate effects of α-crystallin on proliferation of lipopolysaccharide (LPS)-activated retinal microglia and bioactivity of iNOS.Methods The retinal microglial cells cultured in vitro were analyzed and their purity was identified by cell immunofluorescence and flow cytometry.After microglia cells being intervened using LPS and α-crystallin at various concentrations,influence of α-crystallin on activity of LPS-activated retinal microglia was detected by MTT method and level of NO was measured by RT-PCR to observe changes of iNOS expression in microglia.Results Purity of primary cultured microglial cells was 94.15％ by GSA-IB4 immunohistochemical identification and 93.34％ by CD11b flow cytometry.α-crystallin of 10-4g/L awakened activity of microglia induced by 10-6g/L LPS (P ＜ 0.01).Expressions of iNOS protein and mRNA showed significant decrease in combined treatment group (P ＜ 0.05).Conclusion In clinical condition,α-crystallin decreases the harm of microglial cells on retinal ganglial cells (RGCs) after optical nerve injury by inhibiting the microglia cells to produce NO and iNOS.

Objective To explore the relationship among depression,anxiety and social support in elderly patients in community outpatient clinic. Methods A total of 551 elderly outpatients from two com-munity health service centers of Hongkou District in Shanghai were evaluated with patient health question-naire-9 (PHQ-9),generalized anxiety disorder-7 (GAD-7),perceived social support scale( PSSS) for de-pression,anxiety,physical health and social support. Results The prevalence rates of depression and anxiety were 26. 1% and 17. 2%,respectively. The scores of PHQ-9 and GAD-7 were 2. 0(4. 0) and 1. 0(2. 0). There were statistically significant differences in the scores of family support,friend support,other support and social support among the elderly patients with different degrees of depression or anxiety (P<0. 01). Fam-ily support(B=-0. 196) and friend support(B=-0. 171) were protective factors of depression in elderly pa-tients in community outpatient clinic. Age,family support and friend support were protective factors of anxiety in elderly patients,while gender and fluctuation of physical diseases were protective factors of anxiety(P<0. 05). Con-clusions The depression and anxiety is intimately related to social support in elderly outpatients. Appropriate measures should be taken to optimize social support,mitigate bad mood negative improve their quality of life.

Objective:To discover the clinical features of nocturnal enuresis (NE) in adults and to detect factors that correlated with the symptom severity.Methods:This cross-sectional study recruited NE subjects from September 2017 through December 2020. All patients had experienced enuresis at least once per week and with a symptom duration of 3 months or longer. Followed by documentation of history and medical records, three-day bladder diary was adopted to assess their voiding pattern, and urodynamic parameters were obtained to evaluate lower urinary tract function.Results:A total of 106 NE patients (43 male and 63 female) were identified. There is no statistical difference regarding the average age (men: 57.8±15.6 vs. women: 56.1±14.0, P>0.05) and BMI (men: 23.9±3.4 vs. women: 23.3±4.3, P>0.05) between men and women. Comorbidities are extremely common in NE patients (n=85, 80.2%), with the incidence rate higher in men compared to women [88.4% (38/43)vs. 74.6% (47/63), P<0.05]. Hypertension (n=58, 54.7%), hyperlipemia (n=41, 38.7%), diabetes mellitus (n=38, 35.8%), coronary heart disease (n=22, 20.8%) were the most frequently reported conditions. On bladder diaries, subjects were frequently manifested nocturnal polyuria (NP, 47/106, 44.3%), reduced nocturnal bladder capacity (NBC, 74/106, 69.8%), or combination of both(33/106, 31.3%). Urodynamic studies suggested that the incidence of reduce bladder compliance, detrusor overactivity (DO), stress incontinence, bladder outlet obstruction(BOO), detrusor underactivity(DU)and detrusor hyperreflexia with impaired contractility(DHIC)was 27.4%(29/106), 39.6%(42/106), 17.9%(19/106), 9.4%(10/106), 25.5%(27/106)and 15.1%(16/106), respectively. Women were more likely to suffer from stress urinary incontinence [2.3%(1/43) men vs. 28.6% (18/63) women, P<0.01], while men were prone to have bladder outlet obstruction [ 23.3%(10/43) men vs. 0 women, P<0.01]. Correlation analysis demonstrated that obesity( r=0.63, P<0.01), systemic comorbidities( r=0.40, P<0.01), presence of NP( r=0.50, P<0.01) and NP+ NBC( r=0.47, P<0.01), post-void residual( r=0.53, P<0.01), reduced compliance( r=0.21, P=0.04), DU( r=0.28, P<0.01), stress incontinence( r=0.42, P<0.01)and DHIC ( r=0.35, P<0.01)are positively correlated with NE severity. Whereas, reduced Q max( r=-0.35, P<0.01), low capacity( r=0.21, P=0.03), and reduced bladder sensation( r=-0.21, P=0.03) correlate negatively with NE severity. Conclusions:The presence of NE is not only a sign of bladder dysfunction, but also an implication of obesity, systematic chronic diseases, urine production malfunctioning. Therefore, a thorough history regarding the lower urinary tract function and systemic comorbidities should be taken carefully, so that, an integrated and personalized treatment can be carried out.

OBJECTIVE: To explore the clinical characteristics and genetic etiology of a child with multiple pterygium syndrome (MPS). METHODS: A child with MPS who was treated at the Orthopedics Department of Guangzhou Women and Children's Medical Center Affiliated to Guangzhou Medical University on August 19, 2020 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and her parents were also collected. Whole exome sequencing (WES) was carried out for the child. Candidate variant was validated by Sanger sequencing of her parents and bioinformatic analysis. RESULTS: The child, an 11-year-old female, had a complain of "scoliosis found 8 years before and aggravated with unequal shoulder height for 1 year". WES results revealed that she has carried a homozygous c.55+1G>C splice variant of the CHRNG gene, for which both of her parents were heterozygous carriers. By bioinformatic analysis, the c.55+1G>C variant has not been recorded by the CNKI, Wanfang data knowledge service platform and HGMG databases. Analysis with Multain online software suggested that the amino acid encoded by this site is highly conserved among various species. As predicted with the CRYP-SKIP online software, the probability of activation and skipping of the potential splice site in exon 1 caused by this variant is 0.30 and 0.70, respectively. The child was diagnosed with MPS. CONCLUSION The CHRNG gene c.55+1G>C variant probably underlay the MPS in this patient.

OBJECTIVETo observe the impact of plant sterol esters (PSE) mixed in low fat milk powder (2.5 g of PSE/day) on plasma cholesterol levels in hypercholesterolemic subjects during a 6-week intervention period.

METHODSIn this double-blind, randomized, placebo-controlled study, 59 subjects (19 males, mean age (60.28 ± 6.98) years) with primary hypercholesterolemia (fasting LDL cholesterol between 3.4-6.0 mmol/L) were randomly divided into two groups (treatment group, 2.5 g of plant sterol esters a day, n = 30) and placebo group (n = 29). Blood samples were collected at week 0, 3 and 6. The primary outcome was change in plasma LDL-cholesterol (LDL-C). Secondary outcomes were changes in total cholesterol (TC), HDL cholesterol (HDL-C), triglycerides (TG), anthropometry and blood biochemistry.

RESULTSLDL-C significantly reduction from baseline (4.18 ± 0.54) mmol/L to (3.44 ± 0.61) mmol/L (-17.7%, P < 0.05) at week 3 and (3.35 ± 0.39) mmol/L (-19.9%, P < 0.05) at week 6 in the treatment group, whereas in placebo group from (4.11 ± 0.54) mmol/L at baseline to (3.47 ± 0.60) mmol/L (-15.57%, P < 0.05) and (3.61 ± 0.39) mmol/L (-12.17%, P < 0.05) at week 3 and week 6, respectively. TC was reduced from (6.30 ± 0.86) mmol/L at baseline to (5.92 ± 0.75) mmol/L (-6.03%, P > 0.05) at week 3 and (5.43 ± 0.77) mmol/L (-13.8%, P < 0.05) at week 6 in treatment group, from (6.20 ± 0.76) mmol/L at week 0 to (5.70 ± 0.76) mmol/L (-8.06%, P < 0.05) at week 3 and (5.84 ± 0.75) mmol/L (-5.81%, P < 0.05) at week 6 in placebo group. PSE-enriched milk did not affect plasma HDL-C level and TG level at both week 3 and week 6. After normalization to the placebo group, the treatment group showed significant reduction in LDL-C and total cholesteron after 6 weeks. The observed difference of reduction was 7.69% (-0.33 mmol/L, P < 0.05) for LDL-C and 8.00% (-0.51 mmol/L, P < 0.05) for TC between the two groups. There were no significant changes in safety parameters, including blood biochemistry tests during the study period.

CONCLUSIONPlant sterol ester enriched milk powder is effective in reducing LDL-C among Chinese hypercholesterolemic subjects at a dosage recommended by EFSA.

By combing the physiological characteristics of wind and fire， the article makes it clear that wind and fire are evils， and external wind is easy to attack and even worse when it encounters fire； burnt and moving fire evils set off internal winds； and the incitement of each other can lead to the occurrence of palpitations. From the perspective of the theory of "wind and fire inciting each other"， the clinical diagnosis and treatment of palpitation is discussed， which clarifies that there is an internal and external distinction between wind and fire， and there is an internal and external distinction between the real and the imaginary， which should be carefully distinguished in the diagnosis and treatment of palpitation. In the treatment， wind medicine can be skillfully applied to drive away the wind evil to calm the internal and external， and it is also necessary to clearly identify the source of the fire evil and properly choose the corresponding treatment for the fire evil in order to extinguish the burnt fire. As the positive qi exists and the evil will not dry up， we should not forget to take care of the heart in the treatment. An example of a medical case is attached in order to provide new ideas for the clinical treatment of palpitation.

OBJECTIVETo investigate the effect of melatonin (MT) on p38 mitogen-activated protein kinase (MAPK) signaling pathway in rats with phosgene-induced lung injury.

METHODSFifty specific pathogen-free male Sprague-Dawley rats were randomly divided into phosgene inhalation group, air control group, saline control group, MT treatment group, and SB203580 (specific inhibitor of p38 MAPK) group, with 10 mice in each group. All groups except the air control group were exposed to phosgene, and the animals were sacrificed 6 h later. Lung wet/dry weight (W/D) ratio and the content of malondialdehyde (MDA) and nitric oxide (NO) and activity of myeloperoxidase (MPO) in bronchoalveolar lavage fluid (BALF) were measured. The qualitative and quantitative expression of p38 MAPK and phospho-p38 MAPK (p-p38) was measured by immunohistochemistry (IHC) and Western blot, respectively. Inducible nitric oxide synthase (iNOS) level in lung tissue was determined by Western blot.

RESULTSCompared with the air control group, the phosgene inhalation group had significantly increased lung W/D ratio and neutrophil count in BALF (P < 0.01); the MT treatment group had significantly lower neutrophil count and lung W/D ratio than the phosgene inhalation group (P < 0.05). IHC demonstrated that the air control group had relatively weak expression of p-p38 in lung tissue; the expression of p-p38 was significantly up-regulated after phosgene inhalation, and it was mainly distributed in infiltrating inflammatory cells and vascular endothelial cells, positive in the cytoplasm and nucleus of many cells. The distribution of p-p38-positive cells in the MT treatment and SB203580 groups was similar to that in the phosgene inhalation group, but the MT treatment and SB203580 groups had a significantly reduced number of cells with p-p38-positive nuclei and a significantly reduced intensity of p-p38 expression signals. The phosgene inhalation group had significantly increased content of MDA and NO and activity of MPO compared with the air control group (P < 0.01); the MT treatment and SB203580 groups had significantly reduced content of MDA and NO and activity of MPO compared with the phosgene inhalation group (P < 0.05), but had higher content of MDA and NO and activity of MPO than the air control group. The Western blot showed that the phosgene inhalation group had significantly increased expression of iNOS and p-p38 compared with the air control group (P < 0.01); the MT treatment and SB203580 groups had lower expression of iNOS and p-p38 than the phosgene inhalation group (P < 0.05).

CONCLUSIONMT and SB203580 have a significant protective effect in rats with phosgene-induced lung injury, and the mechanism may be associated with scavenging free radicals and inhibiting activation of p38 MAPK and expression of iNOS.

Objective : To evaluate the clinical effect of endoscopic-assisted subgingival scaling and root planning (SRP) in the treatment of periodontitis. Methods: PubMed, EMBASE, The Cochrane Library, Web of Science, CNKI, WanFang Data, and VIP databases were searched for randomized controlled trials (RCTs) related to endoscopy-assisted SRP. The search time limit was from the establishment of the database to September 15, 2021. The outcome indicators included in the study included the plaque index (PLI), probing depth (PD), attachment loss (AL), and bleeding index (BI). Review Manager 5.4 and Stata 12.0 software were used for the meta-analysis. Results: A total of 111 studies were retrieved, and 5 quantitative studies were included after screening. Meta-analysis showed that for sites with 4 mm ≤ PD < 6 mm, 3 and 6 months after treatment, there was no significant difference in the PD value between the endoscope assisted group and the simple SRP group (P > 0.05); for sites with PD ≥ 6 mm, the PD value of the endoscope assisted group was smaller than that of the simple SRP group 3 and 6 months after treatment. The difference between the two groups was statistically significant (P < 0.05), but there was no significant difference in PLI, Al or BI between the two groups (P > 0.05). Conclusion Compared with simple SRP, the auxiliary use of endoscopy has a better effect on reducing PD in deep periodontal pockets (PD ≥ 6 mm). However, for clinical indicators such as PLI, AL, and BI, there was no difference between the therapeutic effects of the two methods.
