Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze epidemiology of gastric cancer five-year survival distribution in Zhejiang population-based cancer registration.Methods:The follow-up data of registrated gastric cancer cases diagnosed from 2008 to 2019 in 22 national cancer registry areas of Zhejiang Province were collected and divided into three diagnostic periods: 2008-2011, 2012-2015 and 2016-2019 to calculate five-year observed survival rates (OSRs), five-year relative survival rates (RSRs) and five-year age-standardized relative survival rates (ARSRs). The distribution of population characteristics (including gender, urban/rural, age group and occupation) and clinical characteristics (including the highest diagnostic institution, sub-site, pathological type and degree of differentiation) of gastric cancer survival rates in each period were analysed.Results:51 663 new cases of gastric cancer in 2008-2019 in the cancer registration area of Zhejiang Province were included in the analysis, and the ARSR of gastric cancer in 2008-2011, 2012-2015 and 2016-2019 showed an increasing trend (39.2%, 41.3% and 44.7%, respectively). In 2016-2019, the ARSR was similar across gender and urban and rural areas (44.4% for men and 45.7% for women; 44.9% in urban areas and 44.2% in rural areas); Among people with different occupations, the ARSR was highest among business and service workers (55.3%), the agriculture, forestry, animal husbandry and fisheries, water conservancy production workers and domestic workers were lower (41.5% and 43.2%, respectively). The highest diagnostic institution was the provincial hospital with a higher gastric cancer survival rate (47.0%) than the municipal (43.4%) and district (43.6%) levels. The ARSR for gastric cancer was relatively high in the lesser curvature (59.7%), pylorus (50.4%), antrum (49.3%), and greater curvature (48.7%), and lowest in cardia (38.9%). Among the major pathological types, adenocarcinoma (NOS) had an ARSR of 48.1%, mucinous adenocarcinoma 41.3%, imprinted cell carcinoma 39.4%, and squamous carcinoma 33.4%. The ARSR for highly differentiated, moderately differentiated, poorly differentiated and undifferentiated gastric cancers were 80.6%, 57.9%, 43.2% and 36.8%, respectively.Conclusion:The 5-year survival rate of gastric cancer in Zhejiang Province is high and on the rise, with similar survival rates in different genders, urban and rural areas, and significant differences in the survival rates of gastric cancer patients with different occupational groups, highest diagnostic institutions, tumour sub-sites, pathological types and differentiation degrees.

OBJECTIVE To investigate the effects and mechanism of atractylodin on inflammatory injury of periodontal tissue and alveolar bone loss in periodontitis rats. METHODS A total of 144 SD rats were divided into control group （intragastric and intraperitoneal injection of normal saline）， model group （intragastric and intraperitoneal injection of normal saline）， atractylodin low-dose， medium-dose and high-dose groups （intraperitoneal injection of 6.665， 13.33， and 26.66 mg/kg atractylodin）， metronidazole group （positive control group， intragastric injection of 0.05 g/kg metronidazole， intraperitoneal injection of normal saline）， AMD3100 [stromal cell-derived factor-1 （SDF-1）/CXC chemokine receptor-4 （CXCR4） pathway inhibitor] group （intragastric injection of 1 mg/kg AMD3100， intraperitoneal injection of normal saline）， atractylodin high-dose+AMD 3100 group （intraperitoneal injection of 26.66 mg/kg atractylodin， intragastric injection of 1 mg/kg AMD3100）， with 18 rats in each group. Except for the control group， all other groups of rats were inoculated with Porphyromonas gingivalis to construct a periodontitis model. After successful modeling， they were given relevant medicine or normal saline， once a day， for 4 consecutive weeks. The gingival index of rats was detected； the levels of interleukin-6 （IL-6） and tumor necrosis factor α （TNF-α） in rat serum were also determined； alveolar bone resorption， periodontal histopathologic changes and the number of osteoclasts were detected by methylene blue staining， HE staining and TRAP staining， respectively. The expressions of osteoprotegerin （OPG）， receptor activator of NF-κB ligand （RANKL）， SDF-1 and CXCR4 proteins were determined. RESULTS Compared with the control group， serious pathological injury of periodontal tissue was found in the model group， the gingival index， the levels of IL-6 and TNF- α， alveolar bone absorption value， the number of osteoclasts， and the expression of RANKL protein were all increased significantly （P＜0.05）， while the expressions of OPG， SDF-1 and CXCR4 proteins were decreased significantly （P＜0.05）. Compared with the model group， pathological injury of periodontal tissue in rats was reduced； the gingival index， the levels of IL-6 and TNF-α， alveolar bone resorption value， osteoclast number and RANKL protein expression were decreased significantly， while protein expressions of OPG， SDF-1 and CXCR4 were increased significantly in atractylodin low-dose， medium-dose and high-dose groups and metronidazole group （P＜0.05）. The change trend of corresponding indexes in the AMD3100 group was opposite to the above （P＜0.05）. AMD3100 attenuated the inhibitory effect of high-dose atractylodin on inflammatory response and alveolar bone loss in rats with periodontitis （P＜0.05）. CONCLUSIONS Atractylodin may improve the inflammatory response and alveolar bone loss in periodontitis rats by activating the SDF-1/CXCR4 signaling pathway.

OBJECTIVE:To explore clinical efficacy and safety of Ulinastatin injection combined with Xingnaojing injec-tion in the treament of severe craniocerebral injury(CCI). METHODS:A total of 120 severe CCI patients selected from our hospital during Sept. 2014-Nov. 2015 were divided into ulinastatin group,Xingnaojing group and combination group according to therapy plan,with 40 cases in each group. Three groups were given routine treatment timely after admission. On the basis of routine treatment,Ulinastatin group additionally received Ulinastatin injection 200 000 U,ivgtt,bid;Xingnaojing group addi-tionally received Xingnaojing injection 20 mL,ivgtt,qd;combination group additionally received Ulinastatin injection com-bined with Xingnaojing injection,same usage as above(with 1 h intervals). Three groups received therapy for consecutive 14 d. Serum inflammatory factors(CRP,IL-1,IL-6,TNF-α),serologic indexes of craniocerebral injury [neuron specific enolase (NSE),myelin basic protein(MBP),S100B protein(S100B)] and GCS scores before and after treatment as well as GOS scores after treatment were all observed in 3 groups. The occurrence of ADR was recorded during treatment. RESULTS:Before treatment,there was no statistical significance in serum inflammatory factors,serologic indexes of craniocerebral injury or GCS scores among 3 groups(P>0.05). Compared to before treatment,inflammatory factors of 3 groups were decreased signifi-cantly after treatment,the ulinastatin group was significantly lower than the Xingnaojing group,combination group was signifi-cantly lower than two single drug groups,with statistical significance(P<0.05). Levels of serologic indexes of craniocerebral injury and GCS scores of 3 groups were improved significantly,and the combination group was significantly better than the two single drug groups,with statistical significance(P<0.05). There was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). Six months after treatment,GOS score of combination group(4.17±0.81)was significantly better than those of ulinastatin group(3.05±0.97)and Xing-naojing group(2.97 ± 0.89),with statistical significance (P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). During treatment,the incidence of ADR in combination group(27.50%)was significantly lower than ulinastatin group(50.00%)and Xingnaojing group(42.50%),with statistical significance(P<0.05);there was no statistical significance between ulinastatin group and Xingnaojing group(P>0.05). CONCLUSIONS:Ulinastatin injection combined with Xingnaojing injection can sig-nificantly decrease serum inflammatory factor levels,relieve craniocerebral injury,protect cerebral tissue and improve short-term prognosis with good safety.

Objective To study the clinical efficacy of platelet-rich plasma (PRP) in the treatment of knee osteoarthritis (KOA) and evaluate whether the age,body mass index and grade of KOA are associated with the treatment outcomes.Methods Using the prospective,randomized,controlled study,100 KOA patients hospitalized between December 2013 and November 2014 were enrolled.Twentyeight patients were men and 72 were women.Mean age was 58 years (range,35-85 years).Degenerative arthritis occurred in 68 patients and traumatic arthritis in 32 patients.Kellgren-Lawrence (K-L) score was grade Ⅱ in 35 patients,grade Ⅱ in 46 and grade Ⅲ in 19.The patients were assigned to receive hyaluronic acid (HA) (HA group,n =50) and PRP (PRP group,n =50) by an intraarticular route once weekly for 3 weeks,according to the random number table.Between-group differences were insignificant in age,gender,body mass index (BMI) and K-L grade.Western Ontario and McMaster Universities Arthritis Index (WOMAC),visual analog scale (VAS) and cartilage lesions score (CaLs) were used for clinical and MRI evaluations.At follow-up evaluation,the effective rate was defined at least 36％ improvement from the baseline WOMAC score.Results All patients were followed up for 6 months.The effective rate in PRP group was 84％ versus 68％ in HA group after the last treatment (P ＞0.05),and was 60％ versus 36％ in HA group at the final follow-up (P ＜ 0.05).WOMAC score in both groups had significant improvement after operation,while VAS improved only in PRP group (P ＜ 0.01).In PRP group patients with K-L grade I had better VAS and WOMAC scores than those with grade Ⅱ (P ＜0.05),and patients with grade Ⅱ had better WOAMC score than those with grade Ⅲ (P ＜ 0.05).MRI findings showed seven patients in PRP group had similar CaLs before and after operation (P ＞ 0.05),and the area of abnormal signal in subchondral bone and the depth of cartilage lesion gradually decreased in one of them.Follow-up study showed the outcomes had negative correlation with age and K-L grade (P ＜0.05),but no certain correlation with BMI in PRP group (P ＞ 0.05).Clinical effects in both groups were decreased over time.Conclusions Intraarticular injection of PRP benefits to pain relief,decreased inflammation and tissue repair,and has much better outcome in patients with younger age and lower K-L grade.However,BMI is not associated with the outcome.

Objective To investigate the formation and special cell biological behavior of osteoclasts.Methods The live-cell imaging technology was adopted to consecutively and dynamically observe the whole process of multinuclear osteoclast formation induced by RANKL and M-CSF from rat peripheral blood monocyte.Meanwhile,the inverted phase contrast microscopy,TRAP staining,and scanning electron microscopy were also applied to identify the osteoclast.Results After 2-week cultivation,a great number of apocytes were found by the inverted phase contrast microscopy,and most apocytes and monocytes had positive reaction after TRAP staining.Moreover,many bone resorption lacunae in which osteoclasts were perhrming bone resorption function could be found in the bone slice under the scanning electron microscope.Live-cell imaging observation showed that the multinuclear osteoclasts were generated through self-fusion of monocytes,fusion of monocytes and apocytes,as well as fusion between apocytes.All fusion processes occurred under the condition of cell adherence.Time-lapse Microcinematography observation showed diverse shapes of osteoclasts and the cell division of multinuclear osteoclasts.Conclusion Rat peripheral blood monocyte can develop into osteoclast under induction of RANKL and M-CSF.Osteoclast can form gigantic apocyte via various types of cell fusion to increase its nucleus number and cell volume,vary its shape,and increase the area of plasma membrane.On the other hand,osteoclast can decrease its cell volume and nucleus number via cell division to adapt the needs of local morphology,biomechanics and bone resorption dynamics.It suggests that this non-mitosis cell division is a special cell biological behavior of osteoclast,which may be the basis of exerting its function and improving bone resorption efficiency.
