Total knee arthroplasty has become one of the effective operation methods on end-stage knee osteoarthritis. However,the postoperative pain has been plaguing the clinicians. The cause of postoperative pain can be divided into iatrogenic, prosthesis and patient. Pain treatment in perioperative period includes preoperative education, analgesia in advance, and the selection and design of reinforcement; during operation mainly includes the appropriate surgical approach, keep the balance of soft tissue around the knee joint, cocktail analgesia pain around the knee joint; after operation mainly includes oral analgesic drugs, femoral nerve tissue and patient controlled analgesia. And the multimodal analgesi.a which is the analgesic methods combined application in perioperative period raised in resent years fully intervene the pain in perioperative period,so that it can effectively reduce the pain of patients after knee replacement, promote the patients do functional exercise more better and get better operation result.

OBJECTIVETo find out an appraisal method of temperature on the first appearance date of Culex tritaeniorhynchus in spring.

METHODSWhole night collection of mosquitoes mosquitoes (from 18:00 hours to 06:00 hours of the following day) with light traps had been carried out in pig sties every night since 1 March in 1982 - 1992 and 2001 - 2002 in Fengxian area Shanghai. The adult mosquitoes caught were anaesthetized, then identified and counted. The density of mosquitoes was calculated by the average number of mosquitos per one trap and one night. Comparative analysis of the mean daily air temperature at 7 days before, the first appearance date and 1 day after, the first appearance date of Culex tritaeniorhynchus.

RESULTSData of the first appearance data of Culex tritaeniorhynchus were judged to mean daily air temperature and cumulative temperature on the day of the first appearance of Culex tritaeniorhynchus and the day before appearance, or 3 days on the day of the first appearance of Culex tritaeniorhynchus and the two days before appearance and the day since appearance with a difference less than 1 - 2 day (91.7%).

CONCLUSIONThe first appearance of Culex tritaeniorhynchus in spring accompanied with a course of influence by the severe warm air advection from south of China, and lowest mean daily air temperature of the first appearance was 11 degrees. Thus the first appearance data of Culex tritaeniorhynchus could be deduced and rehabilitated from observed values of mean daily air temperature or its forecasting values.

Objective To study the early diagnostic predictors and key follow-up parameters for girls with rapidly progressive central precocious puberty (RP-CPP). Methods A total of 260 girls with CPP participated in a prospective, nonrandomized, multi-center, nested case control study. After follow-up six months without any therapy, 114 girls were divided into RP-CPP (n=70) and slowly progressive CPP (SP-CPP) (n=44) groups. Results The basal serum LH and insulin-like growth factor Ⅰstandard deviation score (IGF-ⅠSDS) were the important risk factors of RP-CPP (OR 4.04, 1.578), especially the former. The receiver operating characteristic (ROC) curve revealed that the areas under the ROC curve of basal LH and IGF-ⅠSDS were 0.83 and 0.807, respectively. The levels of basal LH and IGF-ⅠSDS were at 0.52 mIU/ml and 0.35 respectively for the accuracy diagnosis of RP-CPP with the maximum Youden indexs. After follow-up for six months, the change levels of height, breast stages, bone age/chronological age ratio, serum LH, uterine and ovarian volume in RP-CPP group were significantly higher than those in SP-CPP group (all P<0.05). Conclusions The level of basal serum LH and IGF-ⅠSDS may be used as the risk predictors for early diagnosis for girls with RP-CPP. The change levels of basal LH, progress rates of gonad and sex character, height, and impaired growth potential seem to be the key follow-up parameters for CPP progress.

UNLABELLEDobjective: To investigate effects of buyang huanwu decoction (BYHWD) on the rats' myocardial hypertrophic model induced by abdominal aortic constriction, and to clarify the molecular regulatory mechanisms for sarcoplasmic reticulum calcium uptake.

METHODSHypertrophic myocardium rat model was induced by abdominal aorta constriction (AAC). Four weeks after modeling, rats were randomly divided into the sham-operation group (Group S), the AAC model group (Group M), the Enalapril group (Group E), and the BYHWD treatment group (Group BYHWD), respectively. The left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), + dp/dtmax,-dp/dtmax, cardiac output (CO), heart mass index (HMI), and left ventricular mass index (LVMI) were observed in each group after 12-week medication. The serum contents of the atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were detected using ELISA. The SERCA2a activity, the ex- pressions of SERCA2a, phospholamban (PLN), and PLN phosphorylation were observed finally.

RESULTSCompared with Group S, LVSP and LVEDP significantly increased,-dp/dtmax and CO obviously decreased, the myocardial tissue was obviously thickened, the serum contents of ANP and BNP increased, the activity and expression of SERCA2a decreased, the SERCA2a/PLN ratio and PLN phosphorylation degree decreased in Group M (all P <0.05). Compared with Group M, LVEDP obviously decreased, -dp/dtmax and CO obviously increased, the hypertrophy myocardial tissue was obviously lessened, the serum contents of ANP and BNP decreased, the activity of SERCA2a increased, the relative expression contents of SERCA2a, Ser16, and Thrl7 were elevated in Group BYHWD (all P <0.05). BYHWD had significant roles in elevating the SERCA2a/PLN ratio and PLN phosphorylation degree (P <0.05).

CONCLUSIONBYHWD could significantly improve hemodynamics of heart failure rats, elevate CO, lessen cardiac hypertrophy, and improve the capabilities for sarcoplasmic reticulum calcium uptake.

OBJECTIVETo study on growth characteristics of Curcuma wenyujin, and provide theoretical basis for the development of high-quality and high-yield medical material.

METHODThe morphological change of the plant was observed periodically, the content of volatile oil and dry matter in leaves, rhizome, root tuber was determine.

RESULTThe growth of C. wenyujin could be divided into 5 stages, i. e. seed germination, seedling, leaf growth, rhizome expansion, accumulation of dry matter, respectively. Before the stage of rhizome expansion, over 70% dry matter was accumulated in the aerial part of the plant, and during the stage of leaf growth, the maximum increase rate of dry matter in aerial part was 3.90 g/p/d. During the stage of rhizome expansion, the ratio of dry matter of rhizome increased quickly and reached above 33% , and the increase rate of dry matter of rhizome rise up to 3.83 g/p/d, in the end of the stage, the content of volatile oil in the rhizome also rose up to 1.20 mL x 100 g(-1).

CONCLUSIONDuring the whole growth stage, there are two growth centers, when the two curves of dry matter increase of aerial part and rhizome intersect, it is regarded as a signal that the growth transformed form the aerial part to rhizome. When the rate of dry matter from rhizome rise, the content of volatile oil in rhizome rises quickly with the increase of dry matter in rhizome. The optimal harvest time is in mid-December.

Objective:To survey the status quo of family doctor work mode in Shanghai Xuhui district.Methods:Semi-structured and structured in-depth interviews were conducted in Shanghai Xuhui district from April to June 2021, 11 directors, 12 deputy directors in charge and 30 family doctors from 12 community health service centers participated in the survey and completed two stages and four sessions of interviews on the development of the integrated and high-quality family doctor work mode and the ways to realize and the challenges to face. The records of interviews were transcribed, sorted and analyzed using the Colaizzi 7-step analysis method.Results:The survey showed that the family doctor contracting was carried out in a large team mode in the whole district, mainly for the elderly, and most of contracted residents were not included in health management and follow-up services. The team was composed of family doctors and assistants, and the routine outpatient service was the main work pattern, and the regular services also included the chronic disease follow-up and health check-up for elderly. On the issue of how to output high-quality integrated services, the majority of doctors (12/13) believed that the contracted individual should be taken as the unit of fine service, carrying out overall health assessment, optimizing medication plan, lifestyle guidance, one-stop service in hospital, etc.; only one doctor suggested that the family should be the management unit. For upgrading the working mode and service quality, insufficient time and energy were the main obstacle. Public health work occupied a lot of working time, but it seemed not be transformed into favorable resources and conveniences in health management and services. The professional assistants should carry out some responsibility to save family doctor′s time. The survey suggests that informatization, service space, and sufficient drug supply are the keys for ensuring high-quality and high-efficiency integrated services.Conclusion:The organizational structure of the family doctor team in Shanghai Xuhui district is relatively mature, but the integrated and high-quality service output has not yet reached. It is necessary to make regional overall planning and increase efforts to achieve the integration of medical treatment and prevention, so as to gain time for family doctors to carry out high-quality services. At the same time, it is also necessary to cultivate effective family doctor assistants, provide an information work platform that matches the work attributes and goals of family doctors, open up an integrated health management service space, and ensure the full range supply of drugs.

Objective:To observe any effect of supplementing head-eye movement with repeated transcranial magnetic stimulation (rTMS) on the lower limb movement and balance of hemiplegic stroke survivors.Methods:Forty stroke survivors with hemiplegia were divided at random into a control group and an observation group, each of 20. Both groups received conventional medication and head-eye movement rehabilitation training, while the observation group was additionally provided with rTMS daily for 20 days. The head-eye movement training involved one minute for each movement, twice a day, five days a week for 4 weeks. Before and after the treatments, both groups were assessed using the Fugl-Meyer Assessment Scale for the Lower Extremities (FMA-LE), the Berg Balance Scale (BBS), timed up and go tests (TUGs), and the Modified Barthel Index (MBI).Results:The treatment improved both groups′ average FMA-LE, BBS and MBI scores significantly, and significantly shortened their average TUG times. The observation group showed significantly greater improvement than the control group, on average.Conclusion:Combining rTMS with head-eye movement can significantly improve the lower limb movement and balance of hemiplegic stroke survivors.

OBJECTIVETo investigate the value of in vivo proton magnetic resonance spectroscopy (MRS) in the assessment of hepatocellular carcinoma (HCC) and monitor its metabolic change shortly after transcatheter arterial chemoembolization (TACE).

METHODSIn this prospective study, 28 consecutive patients with large HCC (> or = 3 cm in diameter) confirmed by fine needle aspiration biopsy were recruited. The 1H MRS of all hepatic lesions and some uninvolved liver parenchyma were performed with 1. 5T whole body MR scanner. Among them, 15 cases were evaluated again about one week after TACE. The main metabolites such as choline and lipid before and after interventional therapy were measured to assess the early response of the tumor.

RESULTSThe technical success rate of 1H MRS in liver was high (33/41, 80%), closely related to breath motion, location of lesion, and size of voxel. In spectra, the choline compound peak of HCC elevated compared with uninvolved liver parenchyma. After TACE, both the amplitude and the area of choline resonance peak significantly descended (choline-to-lipid ratios from 0.352 +/- 0.080 to 0.167 +/- 0.030, P = 0.026; from 0.205 +/- 0.060 to 0.070 +/-0.020, P = 0.042, respectively); yet lipid resonance peak ascended.

CONCLUSIONSIn vivo 1H MRS is technically feasible for the evaluation of large focal hepatic lesions, however, the reproducibility and stability are not as good as routine MR scan. 1H MRS can monitor the early stage metabolic changes of HCC after TACE but limitation like quantification still exists.
