ABSTRACT
ObjectiveTo investigate the prevalence of overweight or obesity in community patients with schizophrenia in Shanghai and to explore the related factors. MethodsStratified cluster sampling method was used and the general condition， physical examination and laboratory examination data of patients with schizophrenia who voluntarily participated in 2020 free health examination of National Basic Public Health Service were analyzed. ResultsA total of 3 200 patients were included into the study ，and the prevalence of overweight and obesity was 36.75% and 17.19%， respectively. Multivariate logistic regression analysis indicated that age between 40 and 60 （OR=1.333， 95%CI： 1.030‒1.724）， intake of first-generation antipsychotics （OR=1.413， 95%CI： 1.112‒1.796）， intake of second-generation antipsychotics （OR=1.573， 95%CI： 1.288‒1.921）， high-normal blood pressure （OR=1.549， 95%CI： 1.245‒1.927）， high-abnormal blood pressure （OR=2.824， 95%CI： 2.204‒3.619）， elevated ALT （OR=1.874， 95%CI： 1.386‒2.535）， elevated FBG （OR=1.270， 95%CI： 1.066‒1.513）， and elevated TG （OR=1.652， 95%CI： 1.335‒2.044） were the related factors that associated overweight or obesity in patients with schizophrenia. ConclusionOverweight and obesity are highly prevalent among community patients with schizophrenia in Shanghai. Age between 40 and 60， taking first-generation and second-generation antipsychotics， blood pressure higher than 120/80 mmHg， elevated ALT， elevated FBG， and elevated TG are associated with overweight or obesity in patients with schizophrenia. To provide personalized health guidance， medical staff in primary health care institutions should pay more attention to high-risk groups of overweight and obesity in schizophrenia patients at annual physical examination.
ABSTRACT
ObjectiveTo explore the relapse status based on the positive and negative syndrome scale （PANSS Scale） and related factors of schizophrenics in Shanghai communities， and to analyze the association between socio demographic characteristics， lifestyles， clinical characteristics and relapse. MethodsA dynamic cohort prospective study design was used in this study. From March 2018 to February 2019， a total of 189 schizophrenics in Xuhui， Hongkou， Changning， Jiading， Songjiang and Baoshan districts were enrolled successively. Baseline questionnaires were conducted through face-to-face interviews at baseline， which contained social demographic information， lifestyle information and clinical information. A follow-up was conducted every 2 weeks for a measurement of PANSS Scale for a total of 6 months. Relapse was assessed by a PANSS score increase of ≥25% from baseline （or an increase of 10 points or more if the baseline score was ≤40 points）. Univariate and multivariate Cox regression models were used to analyze the associations between relapse status （assessed by PANSS Scale） and socio demographic characteristics， lifestyles， and clinical characteristics， respectively. ResultsA total of 165 community schizophrenics completed baseline and follow-up surveys， with a loss to follow-up rate of about 12.7%. After exclusion of sociodemographic and clinical information deficits， 132 patients were included in the analysis totally， with an average age of 48.18±12.67 years， among whom 41.67% were male. Totally 33 patients relapsed during the 6-month follow-up period， with a relapse rate of 25.0%. After adjusting for gender， family history， age， employment， education， marital status， smoking， drinking， exercise frequency， medication compliance， insight， social function， violence history， stress recent events， adverse drug reactions and baseline scores of PANSS Scale， risk factors of relapse included the following four factors： age below 40 years （HR=4.47， 95%CI： 1.15-17.40）， primary school or below （HR=7.11， 95%CI： 1.54-32.83）， unemployed （HR=8.34， 95%CI： 1.78-38.98）， and adverse drug reactions （HR=5.02， 95%CI： 1.75-14.37）. ConclusionWe should pay attention to the risk factors such as age， education， employment and adverse drug reactions， in order to identify high-risk patients and to conduct timely interventions during the relapse management of schizophrenics in Shanghai community.
ABSTRACT
ObjectiveTo explore the effect of paliperidone palmitate treatment on schizophrenic patients in the community. Methods446 schizophrenic patients who used paliperidone palmitate injection were selected in Shanghai. Before and after the treatment， the disease family burden scale， the concise evaluation scale of drug treatment compliance， the VAS100 score of treatment satisfaction， the short form of quality of life measurement scale， and the screening scale of social function defects were used to evaluate the effects of paliperidone palmitate injection. The data were statistically analyzed using SPSS 26.0 software. ResultsAfter using paliperidone palmitate injection， the total score of family burden （13.94±12.17）， the score of daily family activities （3.26±2.74）， the score of family entertainment activities （2.21±2.30）， and the score of family relationship （2.79±2.76） were significantly higher than those before the treatment （14.98±12.64， 3.51±2.88， 2.48±2.38， 3.11±2.87， respectively， all with P<0.05）. The scores of the World Health Organization on quality of life brief scale （62.89±11.94） and the medication compliance scale （28.11±5.64） were better than those before treatment （60.67±12.62 and 27.37±6.96， all with P<0.05）. Compared with the prior treatment without paliperidone palmitate injection， the number of readmissions after treatment was significantly reduced （P<0.01）. ConclusionThe treatment of paliperidone palmitate injection has significant effect， which can effectively reduce the disease family burden of Schizophrenic patients， improve their quality of life， enhance their drug compliance， reduce the readmission rate of patients， ensure long-term treatment effect and promote disease recovery.

ABSTRACT
ObjectiveTo understand the stress level of people seeking psychological counseling under the coronavirus disease 2019 （COVID⁃19） pandemic and to explore its related factors. MethodsAn online survey was conducted on 1 194 people who sought psychological counseling in Shanghai through the “health cloud” psychological counseling service platform. The questionnaire included demographic information，lifestyle and stress during the COVID-19 pandemic. ResultsParticipants with low，medium，high and very high stress levels accounted for 33.1% （395/1 194），34.6% （413/1 194），25.4% （303/1 194） and 7.0% （83/1 194），respectively. Women and participants aged 18 to 30 years had higher stress levels（Z=-5.368，P<0.001； Z=35.822，P<0.001） compared with other groups. Factors contributing to the rise in stress included reading too much information about COVID-19 （OR=2.057，95%CI：1.012‒4.181），large changes in sleep state （OR=3.496，95%CI：1.669‒7.325），lack of hobbies and interests （OR=2.852，95%CI：1.252‒6.500），and prone to anxiety/irritability/sadness （OR=4.098，95%CI：1.772‒9.480）. Conclusionpeople who sought psychological counseling show high levels of psychological stress during the COVID-19 pandemic. We should pay more attention to the vulnerable groups with the following characteristics： women，18‒30 years old， residents who pay too much attention to the pandemic information，sleep less， and almost lose interest in hobbies， and easily become anxious/irritable/sad.
ABSTRACT
Objective:To investigate the effects of ulinastatin on liver function in patients with liver cancer after major hepatectomy.Methods:The clinical data of 232 patients with major liver resection due to liver cancer were retrospectively analyzed. According to whether ulinastatin was applied after operation, patients were divided into treatment group (105 cases) and control group (127 cases). The postoperative inflammatory factors, liver function, postoperative complications and hospital stay were compared.Results:The levels of CRP、IL-6 and TBIL、ALT、AST were significantly lower than the control group 3 days after surgery (CRP: t=4.520, P=0.000; IL-6: t=17.982, P=0.000; TBIL: t=9.843, P=0.000; ALT: t=11.913, P=0.000; AST: t=4.520, P=0.000). The incidence of massive ascites in the treatment group (χ 2=4.212, P=0.040) and the average postoperative hospital stay ( t=9.994, P=0.000) were significantly lower than that in the control group. Conclusion:Early application of ulinastatin effectively inhibits the inflammatory process, protects liver function, reduces the incidence of massive ascites, and shortens the postoperative hospital stay.
ABSTRACT
Objective To study the effect of the reinforcing and reducing method of acupuncture reported in first Chapter the Nine Needles and Twelve Yuan of the Miraculous Pivot on interstitial fluid pressure (IFP) in subcutaneous tissue of minipig, and to investigate its biomechanical mechanism of regulating the interstitial fluid. Methods Nine healthy minipigs were randomly selected for reinforcing method (pull or press) and reducing method (wave a big pinhole), and tested on soft skin tissues of the abdomen. The IFP in the normal state (NS), the low volume (LV) state (by extracting interstitial fluid) and the high volume (HV) state (by injecting saline solution) was measured before and after acupuncture. Results In the normal state, pulling and pressing the needle could obviously increase IFP, while reducing method could significantly decrease IFP, leading to a rapid decrease in 5 min after acupuncture. In the LV state, pulling and pressing the needle could increase IFP. However, in 10 min after acupuncture, the descend rates of IFP were relatively slower. In the HV state, the reducing method could significantly decrease IFP, and the changing trend in 5 min after acupuncture was different from that of the control group. Conclusions The reinforcing and reducing method of acupuncture could increase or decrease IFP, which proved that the acupuncture method could regulate IFP in the opposite direction. The research findings provide a new scientific basis for using reinforcing and reducing method of acupuncture in clinic.

ABSTRACT
<p><b>OBJECTIVE</b>To observe the impacts of the intervention with electric thermalstone and air suction cup on blood perfusion (BP) at meridian points and explore the approach of accurate measurement and regulation of meridianand blood balance in "precise acupuncture".</p><p><b>METHODS</b>The laser Doppler line scanner (LDLS) was used to measure BP at bilateraln-primary points at the pericardium meridian, the triple energizer meridian, the gallbladder meridian and the liver meridian (small cycle oftomeridians) at 31 healthy receptors. The bias ratio of blood perfusion (BPBR) deviated to the reference value was calculated. The electric thermalstone and air suction cup were used in the intervention at the-sea points of the affected meridians in which BPBR was relatively higher at the-primary points. The electric thermalstone therapy was used when BPBR was less than -30% and the air suction cupping therapy was used when BPBR was higher than 30%. BP was measured twice before intervention and it was measured separately at the moment after intervention and in 20 min after intervention. The means of BP before and after intervention and the change ratio of blood perfusion (BPCR) before intervention, at the moment after intervention and 20 min after intervention were calculated.</p><p><b>RESULTS</b>1. After the intervention of electric thermalstone, BP mean was increased from (103.51±41.21) PU to (121.97±56.22) PU (<0.05). Before intervention, at the moment after intervention and 20 min after intervention, separately, BRCR were (-0.58±16.18)%, (23.58±48.85) % and (25.62±65.89) %. BPCR at the moment after treatment was increased significantly as compared with that before intervention (<0.01). The difference was not significant in 20 min after intervention and before intervention (>0.05), but the change ratio was highly remained. 2. After intervention with air suction cup, BP mean was reduced from (194.83±81.14) PU to (173.88±88.26) PU. Before intervention, at the moment after intervention and 20 min after intervention, separately, BPCR were (7.62±30.49)%, (-12.12±18.20)% and (-14.35±21.25)%. BPCR at the moment after intervention and in 20 min after intervention were significantly different from that before intervention (both<0.01). .</p><p><b>CONCLUSION</b>The electric thermalstone increases the blood flow at the-primary point when acting on the-sea point of the same meridian. The influence of the air suction cup is opposite.</p>
ABSTRACT
Objective:To survey the status of anxiety/depression and lifestyle among junior high school students and explore their relation to put preference for psychological health education.Methods:Totally 1597 junior high school students aged 10 to 17 years in Shang Haicity were surveyed.The Generalized Anxiety Disorder-7 (GAD-7),Patient Health Questiormaire-9 items (PHQ-9) and Chinese Adolescent Lifestyle Scale (CALS),were used to assess anxious emotion,depressive emotion and lifestyle.Results:The rates of anxious emotion and depressive emotion were 16.4％ and 17.2％ respectively among students.Scores of GAD-7 and PHQ-9 were negatively correlated with all factor scores of CALS including eating habits,sleep status,health habits,learning habits,exercise,entertainment activities,interpersonal relationships,coping style and life satisfaction (-0.57 ≤ r ≤-0.15,Ps ＜ 0.01).Multivariate stepwise regression analysis showed that the sleep status factor scores,life satisfaction and exercise factor scores of CALS could negatively predict scores of GAD-7 (β3 =-0.17,-0.15,-0.05;Ps ＜ 0.05) and health habits positively predict scores of GAD-7 (β3 =0.08,P ＜0.001).Sleep status factor scores,life satisfaction factor scores and eating habits factor scores could negatively predict scores of PHQ-9 (β3 =-0.21,-0.16,-0.06;Ps ＜ 0.05).Conclusion:It suggests that the junior high school students'depression and anxiety are related to their lifestyle.The emotion of depression and anxiety of students may be predicted by some factors in the lifestyle.

ABSTRACT
<p><b>OBJECTIVE</b>To investigate the inhibition effect of dopamine on the activity of matrix metalloproteinases (MMP) and the effect of dopamine on degradation of dentin collagen for its potential use in caries treatment and dentin adhesive.</p><p><b>METHODS</b>In the experiment of MMP activity test, 2.0 g/L dopamine + 1.0 g/L highly purified collagenase type VIII from Clostridium histolyticum served as the experimental group, and deionized water + 1.0 g/L highly purified collagenase type VIII from Clostridium histolyticum served as the negative control group, and 2% chlorhexidine + 1.0 g/L highly purified collagenase type VIII from Clostridium histolyticum served as the positive control group, and the mixture volume ratio of the two ingredients in every group was 1:9. After 15 minutes, the enzyme activity of each sample was tested by MMP activity colerimetric quantitative detection kits, and the test was repeated 5 times in each group. In the experiment of collagen degradation, the dentin slices were demineralized with 37% phosphoric acid for 1 min. In sequence, 2 dentin slices were used to observe the morphology, and the remaining 30 dentine slices were randomly divided into three groups (n = 10) according to random number table: the negative control ones were stored in 100 µl deionized water and 900 µl collagenase (7 days, 37 °C), the positive control ones were stored in 100 µl chlorhexidine and 900 µl collagenase (7 days, 37 °C) and the experimental specimens were stored in 100 µl dopamine and 900 µl collagenase (7 days, 37 °C). The degraded collagen was investigated by assaying hydroxyproline. The framework of collagen was evaluated with field emission scanning electron microscope (FE-SEM).</p><p><b>RESULTS</b>The statistical results of completely random design ANOVA showed that the MMP activity and the amount of degraded collagen of the negative control group [(0.089 ± 0.011) µmol · min⁻¹ · mg⁻¹ and (2 837 ± 201) µg/cm²] were significantly higher than those of the positive control group [(0.038 ± 0.006) µmol · min⁻¹ · mg⁻¹ and (1 288 ± 172) µg/cm²] and the experimental group [(0.030 ± 0.009) µmol · min⁻¹ · mg⁻¹ and (1 389 ± 255) µg/cm²] (P < 0.05). SEM observation indicated that the structural integrity of the collagen network on dentin still existed in experiment samples and positive control groups, however, collagen fibrils were destructed and the structural integrity disappeared in the negative control groups.</p><p><b>CONCLUSIONS</b>Dopamine may inhibit MMP activity and reduce the amount of degraded collagen.</p>

ABSTRACT
Objective: To study the effects of Ruanmailing Oral Liquid, a compound traditional Chinese herbal medicine, on spatial learning and memory ability and expression of apurinic/apyrimidinic endonuclease/redox factor-1 (APE/Ref-1) in hippocampal CA1 region in rats with experimental vascular dementia (VaD). Methods: VaD was induced in rats by permanent occlusion of bilateral common carotid arteries. Forty-five VaD rats were randomly divided into untreated group, nimodipine group, low-dose Ruanmailing group and high-dose Ruanmailing group. Another 15 rats underwent a sham operation consisting of similar skin incision and manipulation but without occlusion of carotid arteries. From the next day after occlusion, the rats were intragastrically administered with normal saline, nimodipine suspension or Ruanmailing Oral Liquid respectively for 30 days. Morris water maze experiment was adopted to test learning and memory of rats in each group. Expression of APE/Ref-1 protein in the hippocampal CA1 region was measured by immunohistochemical method. Results: Escape latency was significantly shortened and number of entries in the target area of rats was significantly increased in the high-dose Ruanmailing group as compared with those in the untreated group (P<0.01). Compared with the untreated group, count of APE/Ref-1 positive cells was significantly increased in the hippocampal CA1 region in the high- and low-dose Ruanmailing groups (P<0.01). Compared with the low-dose group and the nimodipine group, the count of APE/Ref-1 positive cells was remarkably increased in the hippocampal CA1 region in rats of the high-dose Ruanmailing group (P<0.01). There was no statistical difference between the low-dose Ruanmailing group and the nimodipine group. Conclusion: Ruanmailing Oral Liquid can improve the learning and memory ability and enhance the lowered expression level of APE/Ref-1 in the hippocampal CA1 region of rats with VaD.
ABSTRACT
To study the role of meridians in the formation and development of diseases, a pathological model of obstructed channel was established by injecting polyacrylamide hydrogel. The effects of blocking low hydraulic resistance channel (LHRC), produced by injecting polyacrylamide hydrogel and by injecting normal saline, were compared by examining the change in transmission of interstitial fluid pressure wave. The results showed that there was significant decrease (P < 0.01) in interstitial fluid pressure wave after more than 0.5 ml polyacrylamide hydrogel was injected into the channel, whereas no significant changes were found after normal saline was injected or when the hydrogel was outside the channel. The above findings demonstrate that the low hydraulic resistance channel can be blocked by injecting certain amount of polyacrylamide hydrogel and a pathological model of obstructed channel has been established preliminarily.

Objective: To observe the influence of transcutaneous CO2emission (TCE) at points on the meridian or beside the meridian after different stimulations like acupuncture De-qi, sham acupuncture, study the correlation between acupuncture De-qi and local energy metabolism through TCE. Methods: Twenty healthy volunteers (male 8, female 12, average age 29 years old) were selected. Before, during and after five different acupuncture Neignan (PC 6), the TCE was measured at Quze (PC 3), point A [at the lower one fourth of line between Tianquan (PC 2) and Quze (PC 3)], point B [at the middle of line between Ximen (PC 4) and Quze (PC 3)], point C (2 cm ulnar side point A) and point D (2 cm ulnar side point B) with a high sensitive C02 instrument (Frewil-Q.F., made in China). The measure results were compared. Results: The comparison on value of TCE before and after the acupuncture, in Sham acupuncture and shallow acupuncture groups, it increased in all five points; in De-qi acupuncture group, there are significant increase on point A, point B, and Quze (PC 3), it has statistic significance, but there are no significant increase on point C and D. After Ximen (PC 4) or Daling (PC 7) were pressed to block Neiguan (PC 6), the value of TCE on Quze (PC 3), point A and point B were decreased during acupuncture Neiguan (PC 6), and increased after the block was removed, but there was no significant difference. Conclusion: Sham acupuncture has also some effects on body, it can increase energy metabolism of local skin, it may be the reason that shallow acupuncture without qi amving can obtain clinical efficacy. The operation method of traditional qi arriving acupuncture can increase energy metabolism of relevant meridian skin, mechanical press can reduce this effect.
ABSTRACT
Objective: In the authors' previous study, acupuncture had an effect along meridians. The effect ofacupuncture can be represented by local energy metabolism which can be expressed by transcutaneous CO2 emission (TCE). To study the transportation of the effect of acupuncture and the influence to the transportation when blocking the meridians, the following experiment was carried out. Methods: Twenty healthy volunteers (male 8, female 12, average age 29) were examined on pericardium meridian at points between Quze (PC 3) and Tianquan (PC 2) (Point a), between Ximen (PC 4) and Quze (PC 3) (Point b), two control points (c and d) beside a and b and Quze (PC 3). TCE was measured on these five points before, during and after acupuncturing Neiguan (PC 6) by a high sensitive CO2 instrument (Frewil-Q.F., made in China). Mechanical pressure of 1 kg (2 cm～ 1 cm area) was given on Ximen (PC 4) or Daling (PC 7) during the acupuncture and TCE were measured before acupuncture, during acupuncture and mechanical pressing, withdrawing acupuncture but keeping pressing and after withdrawing the pressure. Results: TCE increased significantly on point a, b and Quze (PC 3) during and after acupuncture without mechanical press. When mechanical press was given at Ximen (PC 4), no significantly increase was found on above three points during and after acupuncture. When pressing Daling (PC 7), there was still significant (P<0.05) increase at Quz～ (PC 3) and point during acupuncture and significant increase (P<0.05) at point b after acupuncuture while pressing was kept. Conclusion: Acupuncture can enhance the energy metabolism expressed by TCE along meridians and this effect can be eliminated by mechanical pressing along meridians on the way between acupuncture point and measured point.
ABSTRACT
OBJECTIVE: To observe whether injection of medicine into low hydraulic resistance point along meridian brings about higher medicinal effect and to explore the efficacy of the theory that meridians are made up of channels featuring low hydraulic resistance by observing the diuretic effect of injecting furosemide or saline into the low hydraulic resistance point Shuifen (CV 9), vein and Zusanli (St 36) respectively. METHODS: Acute edema was induced in pigs by rapid intravenous injection of 2 000 ml normal saline. The pigs were divided into four groups: Shuifen (CV 9) injection of half dose furosemide group (SFF group), intravenous injection of full dose furosemide group (VF group), Zusanli (St 36) injection of full dose furosemide group (ZSLF group), and Shuifen (CV 9) injection of half dose normal saline group (SFS group). The accumulated urine quantity and the urine quantity generated in every 15-minute period were measured in each group respectively, every 15 minutes after injection, and the measurement lasted for two hours at one experiment. Each group involved eight times of experiments with one pig used for one experiment, which means the whole observation involved 32 times of experiments. RESULTS: The accumulated urine quantities observed in both SFF group and VF group were higher than those in the ZSLF group and the SFS group all through the measurement, showing significant differences during the period from the 15th minute to the 45th minute (P0.05). Analysis of urine quantity generated in every 15-minute period showed that diuretic effect climaxed during the 15th minute to the 30th minute in both SFF group and VF group. By contrast, ZSLF group reached diuresis climax during the 45th minute to 60th minute and no diuresis climax was observed in the SFS group all through the measurement. CONCLUSION: Injection of medicine into low hydraulic resistance point along meridian generates faster and more powerful medicinal potency, and this is likely to be applied to clinical practice. The theory that meridians are channels featuring low hydraulic resistance is important to the elucidation of meridians.
