Abstract
BACKGROUND Upadacitinib, a novel and selective inhibitor of Janus kinase 1, has demonstrated promising efficacy in managing inflammatory bowel disease (IBD). In this systematic review and meta-analysis, our primary aim was to comprehensively assess the therapeutic effectiveness and safety profile of upadacitinib in the treatment of patients with IBD. METHODS We conducted an extensive literature search across prominent databases, including Medline, Embase, Web of Science, and Cochrane Central, to identify pertinent studies providing insights into the efficacy and safety of upadacitinib in IBD. The primary endpoint was the achievement of clinical remission, while secondary endpoints encompassed clinical response, endoscopic response, endoscopic remission, and the evaluation of adverse events (AEs). RESULTS In this meta-analysis of nine studies, we categorized results by study type. Clinical remission rates were: RCTs 36 % (95 % CI = 30-42 %), real-world studies 25 % (95 % CI = 1-49 %), retrospective studies 40 % (95 % CI = 24-56 %), cohort studies 55 % (95 % CI = 25-85 %). Clinical response rates were: RCTs 61 % (95 % CI = 55-67 %), real-world studies 42 % (95 % CI = 14-70 %), cohort studies 65 % (95 % CI = 57-73 %). Endoscopic remission rates were: RCTs 19 % (95 % CI = 15-24 %), cohort studies 29 % (95 % CI = 5-52 %). Endoscopic response rates were: RCTs 41 % (95 % CI = 36-47 %), cohort studies 57 % (95 % CI = 31-83 %). Incidence rate for any AEs: IBD 69 % (95 % CI = 63-76 %), UC 65 % (95 % CI = 57-74 %), CD 75 % (95 % CI = 67-82 %). CONCLUSION Cumulative data from real-world studies and trials confirm the efficacy of upadacitinib in IBD induction and maintenance, with consistent safety. However, further long-term studies are needed to understand its sustained effectiveness and safety.

Abstract
Objective: To investigate the clinical effectiveness of super pulsed carbon dioxide fractional laser debridement surgery on the treatment of chronic wounds. Methods: From December 2018 to May 2019, 37 patients with chronic wounds who met the inclusion criteria were admitted to the Affiliated Hospital of Southwest Medical University for a prospective randomized controlled study. Using the random number table, the patients were divided into surgical debridement group (19 patients, 4 males and 15 females, aged (58±16) years, 25 wounds) and laser debridement group (18 patients, 9 males and 9 females, aged (58±10) years, 23 wounds). In patients of surgical debridement group, oedematous and aging granulation tissue was scraped from the wound by scalpel handle or curet, and the residual necrotic tissue was removed by sharp surgical instruments. In patients of laser debridement group, oedematous and aging granulation tissue and necrotic tissue was removed by super pulsed carbon dioxide fractional laser therapeutic machine, laser gasification debridement was performed repeatedly till fresh normal tissue layer observed. In patients of the two groups, according to the wound in the first 3 d after the first debridement, debridement dressing was performed twice at least as before, then wound debridement dressing was performed once every 1 to 4 days as before according to the wound conditions. The wound healing rates on 7, 14, 21, and 28 d after the first debridement were calculated. The positive rates of bacterial culture of wounds before and after the first debridement were calculated. The color and texture of the wound granulation tissue before the first debridement and on 7, 14, and 28 d after the first debridement were observed and scored. The pain scores before every debridement, during every debridement, and after every debridement dressing change were evaluated by visual analogue scale. The times of debridement dressing change were recorded. Data were statistically analyzed with two independent sample t test, analysis of variance for repeated measurement, Fisher's exact probability test, Mann-Whitney U test, and Bonferroni correction. Results: (1) On 7, 14, 21, and 28 d after the first debridement, the wound healing rates of patients in laser debridement group (29.5% (24.1%, 36.0%), 47.1% (42.7%, 62.4%), 71.4% (62.2%, 76.8%), and 88.6% (79.2%, 96.3%) were significantly higher than those of surgical debridement group (1.6% (1.0%, 12.8%), 12.7% (2.0%, 16.6%), 24.5% (8.9%, 45.5%), 43.9% (23.2%, 70.8%), Z=3.477, 3.553, 2.721, 2.193, P<0.05 or P<0.01). (2) Before the first debridement, the positive rates of bacterial culture of wounds in patients of laser debridement group and surgical debridement group were 92% (23/25) and 91% (21/23), respectively, which were similar (P>0.05). After the first debridement, the positive rate of bacterial culture of wounds of patients in surgical debridement group was 64% (16/25), which was significantly higher than 13% (3/23) of laser debridement group (P<0.01). (3) On 7, 14, and 28 d after the first debridement, the scores of color and texture of wound granulation tissue of patients in laser debridement group were significantly higher than those of surgical debridement group (Z=3.420, 5.682, 6.142, 4.461, 5.337, 4.458, P<0.01). (4) The pain scores during every debridement and after every debridement dressing change in patients of laser debridement group were significantly lower than those of surgical debridement group (t=2.847, 5.046, P<0.05 or P<0.01). (5) The time of debridement dressing change in laser debridement group was 8.0 (7.0, 10.0) times, which was significantly less than 10.0 (9.5, 12.5) times in surgical debridement group (Z=2.261, P<0.05). Conclusions: Compared with traditional surgical debridement method, super pulsed carbon dioxide fractional laser debridement surgery is more effective in treating patients with chronic wounds. Laser debridement makes the wound healing more efficiently with reduced pain and better infection control; significantly reduces the number of dressing changes, and is especially suitable for the wound treatment in outpatients.

Abstract
Objective: To evaluate the clinical efficiency of an iris hook combined with a modified double-eyelet capsular tension ring (MCTR) in the treatment of serious lens subluxation. Methods: Retrospective case series. A total of 16 patients (20 eyes) with serious lens subluxation were enrolled in Zhongshan Ophthalmic Center from March 2016 to December 2016. All the patients had an iris hook inserted to support the capsule during the phacoemulsification. Then an MCTR was implanted and sutured onto the sclera. Both intraoperative and postoperative complications, such as posterior capsular opacification and macular edema, were recorded. The postoperative examinations included visual acuity, intraocular pressure, slit-lamp examination, and Pentacam for evaluation of the positions of the capsule and the intraocular lens(IOL). The best corrected visual acuities before and after operation were compared with the matched t test. Results: There were 11 males(12 eyes) and 5 females (8 eyes) among the 16 patients (20 eyes) aged (36±16) years, including 5 cases of Marfan's syndrome (7 eyes), spontaneous ectopia lentis in 7 patients (9 eyes), and traumatic lens dislocation in 4 patients (4 eyes). All the MCTRs were successfully implanted into the capsule. The best corrected visual acuity ranged from 0.3 to 1.0, with 0.5 or higher accounting for 90% (18 eyes). It was 0.20±0.14 and 0.21±0.13, respectively, at 3 and 6 months, which was significantly better than the preoperative best corrected visual acuity (logarithm of the minimal angle of resolution) (0.74±0.51;t=5.302, P<0.001; t=5.131;P<0.001). One eye had macular edema 3 months after surgery, and then was treated by conservative management. Two eyes(2 case) developed mild posterior capsular opacification 6 months after operation. No intraocular hypertension was persistently observed. All IOLs and capsular bags were in the expected position without an obvious tilt or displacement. Conclusion: The surgical strategy of iris hooks combined with MCTRs in the treatment of serious lens subluxation could maintain long-term stability of the capsule.

Abstract
In Weifang Prefecture, Shandong Province, and Wenshan Prefecture, Yunnan Province of China, leprosy was highly prevalent in the 1950s. Due to differences in geographical conditions and socioeconomic development, the decline in leprosy prevalence between 1955 and 1993 was 99.5% (10.1 to 0.05/10,000) in Weifang and 93.9% (19.7 to 1.2/10,000) in Wenshan. The decrease in the detection rate was 99.9% (35.2 to 0.05/10,000) in Weifang and 91.7% (69.9 to 5.8/10,000) in Wenshan. The decrease was more apparent in these two prefectures since the implementation of multidrug therapy (MDT) in 1986. Findings such as specific detection rates by age, sex and type, as well as the multibacillary, child, and deformity rates of patients detected since 1980 were studied. Using the detection and prevalence rates between 1980 and 1993, the number of patients until the year 2000 is extrapolated for these two prefectures.

Abstract
In order to confirm the existence of insulin resistance in spontaneously hypertensive rat (SHR), rich musculature glucose tolerance test (GTT) and histological method examination of the insulin receptor were carried out in SHR and the normotensives (WKY). The basal serum insulin level was higher and the area under insulin curve during GTT was also higher in SHR than those in WKY, while the basal serum glucose level and the area under glucose curve during GTT in SHR were similar to those in WKY. As compared with WKY, SHR displayed a significantly lower percentage of insulin sensitive slow-twitch fiber of plantaris and medial head of gastrocnemius (type I fiber). There were strong positive correlations between blood pressure (BP) and insulin as well as between BP and the area under insulin curve, but the correlation between insulin and percentage of type I fiber was negative. In conclusion, the present study provides both functional and structural evidence of insulin resistance in SHR.

Abstract
Previous studies have shown the effects of atrial natriuretic factor (ANF) on rats with renovascular hypertension (RVH). In the present study low dose alpha-hANF (0.025 microgram/kg/min) was administered intravenously for 60 minutes to seven RVH patients. Results demonstrated an inhibition of renin-angiotensin-aldosterone system (RAAS), reduction of plasma catecholamine and arginine vasopressin(AVP), diuresis and natriuresis, increase of hematocrit and creatinine clearance, and slight decrease of blood pressure. These results showed that most factors involved in the establishment and maintenance of RVH are affected by ANF infusion.

Abstract
Five hundred patients with aortoarteritis were studied in this series. The long-term administration of small dosage of corticosteroid is effective in treating this disease in its active stage. The patients with renal vascular hypertension should be treated by percutaneous transluminal renal angioplasty or by surgery if indicated. About one third of the pulsations of the involved arteries were improved. The incidence of complications was 17% and the mortality rate was 11% in this series. Cerebral thrombosis was found as a common complication and hemorrhage as a common cause of death. Three patients died of heart failure without aortic regurgitation. Five-year and ten-year survival rates were 93.1% and 91.1% respectively.

Abstract
The causes of elevated intra-erythrocyte calcium in the offspring of essential hypertensive patients are unknown. Fourteen children with and without a family history of essential hypertension were chosen to compare erythrocyte membrane Ca2(+)-Mg2(+)-ATPase activity (Rbc-M Ca2(+)-Mg2(+)-ATPase activity) measured by biochemical methods. We found that Rbc-M Ca2(+)-Mg2(+)-ATPase activity was lower in children with family history of hypertension compared with children with no family history (2.16 +/- 1.10 vs 3.36 +/- 1.19 microM Pi/mg protein/hour P less than 0.01). These results suggest that the reduced Rbc-M Ca2(+)-Mg2(+)-ATPase activity may be one of the mechanisms causing the high erythrocyte calcium levels in the offspring of essential hypertensive patients.

Abstract
We report 480 patients with aorto-arteritis studied in our group. Among 320 patients, who were diagnosed by aortography the female to male ratio was 2.8:1, and the age of onset ranged from 5-45 years. The patients were followed for 1-27 years (average 6.8 years). Two hundred and eighty-six (59.6%) patients with renovascular hypertension were found in the group. All patients were treated with medical or surgical procedures. One hundred and thirty patients with renovascular hypertension were operated upon by revascularisation or uninephrectomy and 11 patients with renal artery stenosis were subjected to percutaneous transluminal renal angioplasty. There were 55 deaths (11.5%) in the group, cerebral haemorrhage being the major cause of death. Five year and ten year survival rates were 93.1% and 91.1% respectively.

Abstract
This study on the thymus and spleen development and ADA activity was done in young rats with zinc deprivation and supplementation. The serum zinc level, body weight, absolute and relative weight, and ADA activity of the thymus and spleen were compared between the experimental rats and the control group. Above indications were all decreased; especially both the thymus weight and the thymus ADA activity were markedly decreased in the zinc deficient group. The averages of thymic absolute weight, relative weight and ADA activity were dropped by 61.32%, 54.54% and 47.59%, respectively. After zinc supplementation for one month, all the body weight, weight of the thymus and spleen, and ADA activity of the spleen were recovered to the control group's level, while ADA activity of the thymus was 33.03% higher than that of the control group. Our data suggested that zinc was not only an important trace element in maintaining the growth of the body, the development of the thymus and spleen, but it may be an important agent to activate the ADA or to prompt synthesis of ADA.

Abstract
Mixed longitudinal data of length and weight growth from 595 rural and 337 urban infants were analysed. Count models were fitted to the means of length and weight in different ages, sexes and feedings separately. The curve fitting to the data was rather satisfactory. Comparison of model parameters between urban and rural infants suggested that rural infants had a higher length level at birth but lower accelerative growth afterwards than urban ones, which was even more obvious in breast-fed infants. The difference in birth weight between them was not significant; and the urban infants had a faster linear growth velocity than rural ones. These results might be caused by the fact that food supplementing in urban infants was significantly earlier and better than in rural ones.

Abstract
Ten cases of aortic regurgitation in the patients with aortoarteritis in our group were studied during the period 1958-1988. Nine out of 10 patients with aortoarteritis were performed by aortography. The incidence of aortic regurgitation is 2.2 per cent in 450 patients with aortoarteritis. In all the patients with aortic regurgitation diastolic murmurs were heard in the aortic valves. X-ray findings showed dilatation of ascending aorta with aortic regurgitation in 10 patients and enlargement of left ventricle in 7 patients. Subclavian artery and carotid artery were involved in all patients. Descending aorta or abdominal aorta were also involved in 6 of them. Two patients with angina pectoris were studied by coronary arteriography and the coronary arteries were normal. Clinically, these cases should be differentiated from aortic regurgitation of other etiology.

Abstract
Variability of urine sodium (Na), potassium (K) and sodium/potassium (Na/K) excretion was studied in a sample of 50 employed normotensive male health professionals aged 27-50 in Beijing, China. Six 24-h urine specimens were collected from each participant during night-time (12-h) and daytime (12-h) fractions. The estimated ratio of intra- to inter-individual variances was 2.12 for night-time and 1.48 for 24-h urine Na, and 1.85 and 1.54, respectively, for urine K. Based on these values, six night-time and four 24-h urine specimens are necessary to reduce to 15% the diminution of a correlation between urine Na and another physiological variable. The corresponding numbers are five and four, respectively, for urinary K measurement. These data suggest that the ratio of within-person variation to between-person variation in Na excretion is smaller in these Chinese men than in Americans. The dietary Na intake of Chinese men can therefore be characterized with fewer urine specimens than are required for western populations. Night-time urinary Na and K showed good concordance with those from 24-h specimens in distinguishing high or low Na and K intake. These findings indicate that in large-scale epidemiological studies, overnight specimens may be adequate for classifying individuals with regard to Na and K intake.
